The New England Bee Hotel For Pollinators

A newly constructed “bee hotel” at the University of New Hampshire’s Woodman Farm isn’t much to look at — with its cinder block floors and pine cone-littered suites — but for the region’s pollinators, it’s as appealing as any five-star resort.

The bee hotel is at the center of the first-ever comprehensive study of New England’s bee population. The study, led by researchers at the University of New Hampshire’s New Hampshire Agricultural Experiment Station (NHAES), aims to assess the condition of the region’s estimated 250 species of bees.

“The study will establish the first complete diversity assessment of native bees in the region and also provide a better understanding of pollinator diversity and ecology,” Sandra Rehan, lead NHAES researcher and assistant professor of biological sciences at the University of New Hampshire’s College of Life Sciences and Agriculture (COLSA), said in a statement.

The study, called “Sustainable Solutions to Problems Affecting Bee Health,” was launched to coincide with National Pollinator Week (June 16-22), an annual event sanctioned by the U.S. Secretary of Agriculture that highlights the urgent issue of declining pollinator populations in the United States.

“Basic data on species diversity and habitat preferences will be fundamental to future studies to ameliorate declining bee populations and to target species at risk,” Rehan said.

In addition to helping protect native bees in New England, Rehan said the project is designed to raise awareness about how humans are affecting pollinator populations in the region, as well as across other areas of the country.

Bees, which play a critical role in the health of food crops and natural ecosystems, have experienced rapid declines in population and diversity over the past several years, research from NHAES shows.

And humans deserve at least part of the blame for this decline. Loss of habitat and agricultural environments, as well as the widespread use of pesticides and chemicals in farming, are believed to be contributing to the current bee crisis throughout the United States.

 

The value of pollination to agriculture is estimated at more than $200 billion each year worldwide, said Rehan, who oversees the University of New Hampshire’s Bee Lab.  This makes the university’s research into the subject even more pressing, and has led to the launch of a longer-term project to monitor the biodiversity of bees in New Hampshire. The bee hotel at Woodman Farm represents one part of this project, with other monitoring sites at NHAES facilities also contributing much-needed data.

“By documenting what species are abundant, common and rare to the area, we can track species habitat and floral preferences,” Rehan said.  “By further developing long-term monitoring, we can identify species at risk and changes in bee communities.”

The researchers plan to use genomic screening on the winged guests of the bee hotel to identify which species suffer low genetic variability. This trait, the researchers explained, may indicate certain genetic issues that can lead to the decline or even extinction of a species.

John Wraith, NHAES director and dean of the College of Life Sciences and Agriculture, expressed enthusiasm for the bee hotel project and its related studies, noting the impact that pollinators have in New Hampshire and its neighboring regions.

“These are critically important, time-sensitive issues that face our state and regional producers, gardeners, residents and visitors,” Wraith said in a statement.

“We’re excited to support this work within our engaged research portfolio.”

 

Rehan is equally excited about the studies, and hopes that continued research and education can help reverse the trend in declining bee populations in New England and other regions.

“By educating New Hampshire citizens, farmers and policymakers about native bees and habitat preferences, we can encourage the regional and national authorities to create and maintain native bee habitats,” Rehan said.

Meditation Found To Help With Anxiety And Depression?

According to recent research from John Hopkins Research, 30 minutes of meditation can possibly help ease the symptoms of anxiety and depression. asics onitsuka tiger donna But how exactly does it work?

The researchers evaluated the degree to which those symptoms changed in people who had a variety of medical conditions, such as insomnia or fibromyalgia, although only a minority had been diagnosed with a mental illness. Canotta Milwaukee Bucks MadhavGoyal, an assistant professor in the Division of General Internal Medicine at the Johns Hopkins University School of Medicine and his colleagues found that so-called “mindfulness meditation” — a form of Buddhist self-awareness designed to focus precise, nonjudgmental attention to the moment at hand — also showed promise in alleviating some pain symptoms as well as stress. New Balance 998 mujer The findings held even as the researchers controlled for the possibility of the placebo effect, in which subjects in a study feel better even if they receive no active treatment because they perceive they are getting help for what ails them.

To conduct their review, the investigators focused on 47 clinical trials performed through June 2013 among 3,515 participants that involved meditation and various mental and physical health issues, including depression, anxiety, stress, insomnia, substance use, diabetes, heart disease, cancer and chronic pain. Maglie New Orleans Pelicans

They found moderate evidence of improvement in symptoms of anxiety, depression and pain after participants underwent what was typically an eight-week training program in mindfulness meditation. Canotte Selección de USA They discovered low evidence of improvement in stress and quality of life. Trevor Siemian Jerseys There was not enough information to determine whether other areas could be improved by meditation. store locator for new balance shoes In the studies that followed participants for six months, the improvements typically continued.

Mindfulness meditation, the type that showed the most promise, is typically practiced for 30 to 40 minutes a day. Cheap Nike Trainers UK It emphasizes acceptance of feelings and thoughts without judgment and relaxation of body and mind. Nike Air Max Goedkoop He cautions that the literature reviewed in the study contained potential weaknesses.

Saturn’s Polar Hexagon Explained

This may seem like an odd thing for a bee-based skincare and honey site to be posting about, but we love all aspects of what makes up a beehive. One of those very important things is the shape of the honeycomb. fjallraven kanken classic 16 L A hexagon is the most erognomic shape and the perfect match for something as complex yet simple as a honeycomb. Adidas Pas Cher So whenever we see interesting news related to our favourite shape, we just have to share it, and what’s more fascinating than a naturally occurring hexagon on Saturn?

The unusual structure with a hexagonal shape surrounding Saturn’s north pole was spotted on the planet for the first time thirty years ago. Nothing similar with such a regular geometry had ever been seen on any planet in the Solar System. Womens Air Jordan 5 The Planetary Sciences Group has now been able to study and measure the phenomenon and, among other achievements, establish its rotation period. What is more, this period could be the same as that of the planet itself. Saturn is the only planet in the Solar System whose rotation time remains unknown. The research illustrates the front cover of the journal Geophysical Research Letters and has been highlighted by the publication’s editor.

In 1980 and 1981 NASA’s Voyager 1 and 2 space probes passed for the first time over the planet Saturn, located 1,500 million km from the Sun. Among their numerous discoveries they observed a strange, hexagon-shaped structure in the planet’s uppermost clouds surrounding its north pole. Air Jordan 2 Retro The hexagon remained virtually static, without moving, vis-à-vis the planet’s overall rotation that was not accurately known. Dennis Pitta Ravens Jerseys What is more, the images captured by the Voyager probes found that the clouds were moving rapidly inside the hexagon in an enclosed jet stream and were being dragged by winds travelling at over 400 km/h.

Thirty years later –the equivalent of one Saturn year, in other words, the time the planet takes to go all the way around the Sun– and over more than six consecutive years, researchers in the UPV/EHU’s Planetary Sciences Group, in collaboration with astronomers from various countries, were able to observe Saturn’s northern polar region in detail once again and confirmed that the hexagon continued in place.

  • Air Max 90 Floreale
  • After measuring the positions of the hexagon vertices with great precision, they determined that its movement remains extremely stable, and on the basis of the cloud movements, that the jet stream inside it remains unchanged. For this study the researchers used images taken from the Earth between 2008 and 2014; they used, among others, the astronomical cameras PlanetCam (developed by the Planetary Sciences Group itself) and Astralux, fitted to the telescopes of the Calar Alto Observatory in Almería (Spain); in addition, they used the very high resolution images obtained by t he Cassini spacecraft, which has been orbiting Saturn since 2004. New York Giants Jerseys

    Due to the tilt of approximately 27º of the planet Saturn, its polar atmosphere undergoes intense seasonable variations with long polar nights lasting over seven years, followed by a long period of 23 years of variable illumination. However, the seasonal variations do not affect the hexagon and its jet stream at all, so both are part of an extensive wave, deeply rooted in Saturn’s atmosphere. Fjallraven Kanken Kids UK The UPV/EHU researchers suggest that the hexagon and its stream are the manifestation of a “Rossby wave” similar to those that form in the mid-latitudes of the earth. On our planet the jet stream meanders from west to east and brings, associated with it, the system of areas of low pressure and anticyclones which we have been seeing regularly on weather maps.

    On Saturn, a hydrogen gas planet, ten times the size of the Earth, cold in its upper clouds, without a solid surface, and with an atmosphere as deep as that of an ocean, “the hexagonal wavy motion of the jet stream is expected to be propagated vertically and reveal to us aspects of the planet’s hidden atmosphere,” pointed out Agustín Sánchez-Lavega, Head of the Planetary Sciences research group. cheap jordans uk “The movement of the hexagon could therefore be linked to the depths of Saturn, and the rotation period of this structure, which, as we have been able to ascertain, is 10 hours, 39 minutes and 23 seconds, could be that of the planet itself,” he added.

    Radio Tagging Bees – For Science!

    Miniature radio tags, kind of like toll cards for cars, are being attached to the back of bees to help them survive the threat of exotic diseases.

  • ADIDAS ULTRA BOOST Uncaged
  • Five thousand tags are being fitted to bees in southern Tasmania. Justin Forsett Ravens Jerseys The information they generate will be used to learn more about bee movement and behaviour.

    CSIRO Science Leader Dr Paulo de Souza has been instrumental in developing the tiny radio frequency identification sensor. Yadier Molina Jersey He says the technology works because bees are social animals: “Because the communication range we have today is pretty short, we can read the data about 30 centimetres away. nike air max 1 pas cher So if we have an insect that passes a specific place that we can read the data, that will help us a lot.”

    Beekeeper Peter Norris is hopeful the technology can be used to eradicate the exotic Asian Honey Bee, found in Queensland. New Balance buty damskie “It’s fantastic for our industry, particularly if we can get to the point where we can take GPS readings.

  • NIKE AIR MAX 90 GOEDKOOP
  • It would be a real breakthrough from a pollination point of view for working out pollination densities.

    “But probably one of the major things I’d like to see it used for is eradicating Apis cerana, which was an incursion in Cairns in 2007. Scarpe Kobe 11 Unfortunately it wasn’t eradicated and it’s now moved to a management situation. adidas yeezy boost 750 męskie But with this chip, if we could trap Apis cerana at feeding stations, we could get GPS readings of where the nests are. Nike Air Max Flyknit Heren We would be in a position to eradicate it.”

    Dr de Souza says that, in the future, even smaller radio transmitters could be used to study Queensland fruit fly, an increasingly concerning issue in New Zealand.

    Honey Found To Help Antibiotic Resistance

    Medical professionals sometimes use honey successfully as a topical dressing, but it could play a larger role in fighting infections, researchers told a meeting of American Chemical Society recently.

    “The unique property of honey lies in its ability to fight infection on multiple levels, making it more difficult for bacteria to develop resistance,” said study leader Susan M. Kenley Jansen Authentic Jersey Meschwitz, Ph.D. That is, it uses a combination of weapons, including hydrogen peroxide, acidity, osmotic effect, high sugar concentration and polyphenols — all of which actively kill bacterial cells, she explained. The osmotic effect, which is the result of the high sugar concentration in honey, draws water from the bacterial cells, dehydrating and killing them.

    In addition, several studies have shown that honey inhibits the formation of biofilms, or communities of slimy disease-causing bacteria, she said. Nike Air Max 2016 Dames Zwart “Honey may also disrupt quorum sensing, which weakens bacterial virulence, rendering the bacteria more susceptible to conventional antibiotics,” Meschwitz said. Nike Air Max 95 męskie Quorum sensing is the way bacteria communicate with one another, and may be involved in the formation of biofilms. nike scarpe italia In certain bacteria, this communication system also controls the release of toxins, which affects the bacteria’s pathogenicity, or their ability to cause disease.

    Meschwitz, who is with Salve Regina University in Newport, R.I., said another advantage of honey is that unlike conventional antibiotics, it doesn’t target the essential growth processes of bacteria. adidas ultra boost hombre The problem with this type of targeting, which is the basis of conventional antibiotics, is that it results in the bacteria building up resistance to the drugs.

    Honey is effective because it is filled with healthful polyphenols, or antioxidants, she said. buty Asics Męskie These include the phenolic acids, caffeic acid, p-coumaric acid and ellagic acid, as well as many flavonoids. “Several studies have demonstrated a correlation between the non-peroxide antimicrobial and antioxidant activities of honey and the presence of honey phenolics,” she added. new balance 997 on sale A large number of laboratory and limited clinical studies have confirmed the broad-spectrum antibacterial, antifungal and antiviral properties of honey, according to Meschwitz.

    She said that her team also is finding that honey has antioxidant properties and is an effective antibacterial. Air Jordan 9 Retro “We have run standard antioxidant tests on honey to measure the level of antioxidant activity,” she explained. “We have separated and identified the various antioxidant polyphenol compounds.

    Honeybees Reveal That Evolution Is Stranger Than You Ever Realized

    Note: This article was first published in io9 on 3/6/14.

    Darwin’s idea of natural selection is simple. Good mutations are passed on, because the animals who have them will survive to reproduce. Philadelphia 76ers But how do you pass on those good mutations in honeybee colonies, where most bees are sterile workers who never have babies? A group of researchers decided to find out.

    York University biologist Amro Zayed worked with a team of Canadian and Saudi Arabian researchers to unravel a genetic mystery that has long intrigued evolutionary biologists. nike kd 9 pas cher Worker bees are the most important part of any bee colony, gathering food, building the hive, taking care of babies, and maintaining the temperature inside the hive at what Zayed calls a “balmy 33 degrees Celsius.” If a worker has a mutation that makes it better at finding food in a new region, evolutionary reason would predict that mutation ought to be passed along to the next generation of workers. But how can it be, if only the queen bee is having babies?

    In the 1960s, W.D. Hamilton first proposed a theoretical model that could explain how each generation of sterile bees contributed to the fitness of their species. The theory was called “kin selection,” and it suggests that non-reproducing animals still benefit when another member of their group is having babies. As the term “kin selection” suggests, a sterile bee is still helping natural selection along, even if it’s only by making it easier for her queen to lay eggs. After all, the queen is either mother or sister to every bee in her colony.

    For decades, kin selection was just a theory. New Balance Niño Recently, however, we’ve accumulated enough genetic information about honeybees that we’re able to analyze how they’re evolving at a DNA level. And a few years ago, Zayed and his colleagues wondered whether they could use genetic evidence to back up Hamilton’s fifty-year-old idea. First, they gathered 40 honeybee genomes from subspecies regions all over Africa, Asia, the Middle East and the Americas. “One researcher even risked great danger to get a honeybee in Syria,” Zayed said.

    After an intensive analysis, the team discovered that there are certain regions of the honeybee genome that are undergoing rapid positive selection. That means they found several relatively new mutations that have spread quickly throughout honeybee subspecies because they are so useful. And nearly all of those mutations were associated with honeybee workers’ ability to adapt their behavior to new environments and manage the worker division of labor. Maglie Los Angeles Lakers Essentially, all the most rapidly-changing parts of the honeybee genomes were selecting for traits that gave advantages to those sterile workers.

    If you think about a bee colony, the queen bee is living in an almost lab-like environment. She’s fed and groomed by workers. The temperature in the colony is 33 degrees Celsius for most of her life. She’s in this benign environment, afforded by the actions of workers who collect food and nurse the brood and thermo-regulate the hive. Air Jordan 3 Uomo Through their behavior they bear brunt of changes in environment. They have to cope with changes in environment. New York Giants Jerseys And they deal with changes in the environment with changes in worker behavior.“This is the first time anyone has shown workers contributing to adaptation,” Zayed told io9 by phone from Ontario, Canada. And he said it makes perfect sense, considering that workers are the front line when it comes to the colony’s survival in the environment. But the queen doesn’t need to adapt as much, because her environment is always stable. Canotte Boston Celtics Zayed continued:

    And indeed, as Zayed’s team found, the DNA regions that are evolving the most rapidly in honeybees are responsible for worker behavior.

    Again, we have to ask, how are these good traits being passed on from one sterile generation to the next? The answer takes us back to kin selection. The better the workers are, the more likely their queen’s hive environment will remain stable and benign. Canotte Charlotte Hornet And that means she’s more likely to have more children, many of whom will also have the good mutations that made her workers so adaptable in the first place. nike air max pas cher Among those children will be future queens, who will carry those genes with them when they found new colonies and birth new generations of workers.

    This also helps explain why there is such a huge amount of variation in honeybee behavior from subspecies to subspecies — and even from colony to colony. Zayed pointed out that the famously aggressive behavior of African honeybees is a direct result of adapting to an environment full of predators like the honey badger who attack hives. In other parts of the world, such as Yemen, bees have adapted to be excellent at air conditioning their hives in the hot desert air. And in Japan, bees have used the “hot defensive bee ball” to combat deadly wasps. All of these behavior modifications are the result of rapid changes under the pressures of natural selection.

    As a result of Zayed and his colleagues’ work, published last month in the Proceedings of the National Academy of Sciences, we have solid genetic evidence that even when animals don’t reproduce, they still contribute to the evolution of their species and their family lineage. Put another way, altruism pays off.

    Though humans are very different from social insects, there is still something poignant in the life cycles of honeybees for us city-dwelling Homo sapiens. It’s hard not to ponder the implications of those queens with their static, unchanging behavior inside the hive. Their evolution is entirely dependent on adaptable sisters and daughters, working in the dangerous world outside. And yet the workers can’t pass along the behaviors they’ve evolved without their queen. It sounds harmonious.

    Halloween Week: Help Scientists Battle Zombees

    Honey bee colonies are subject to numerous pathogens and parasites. Adrian Gonzalez Jersey Interaction among multiple pathogens and parasites is the proposed cause for Colony Collapse Disorder (CCD), a syndrome characterized by worker bees abandoning their hive. Last year scientists from the San Francisco State University provided the first documentation that the phorid fly Apocephalus borealis, previously known to parasitize bumble bees, also infected and eventually killed honey bees and may pose an emerging threat to North American apiculture.

    Scientists say the fly deposits its eggs into the bee’s abdomen, causing the insect to walk around in circles with no apparent sense of direction. The bee exhibits zombie-like behaviour, said lead investigator John Hafernik. Parasitised honey bees show hive abandonment behavior, leaving the hive at night and dying shortly thereafter. On average, seven days later up to 13 phorid larvae emerge from each dead bee and pupate away from the bee. Using DNA barcoding, the researchers confirmed that phorids that emerged from honey bees and bumble bees were the same species.

    Microarray analyses of honey bees from infected hives revealed that these bees are often infected with deformed wing virus and Nosema ceranae. Larvae and adult phorids also tested positive for these pathogens, implicating the fly as a potential vector or reservoir of these honey bee pathogens. Air Jordan 5 Uomo Phorid parasitism may affect hive viability since 77% of sites sampled in the San Francisco Bay Area were infected by the fly and microarray analyses detected phorids in commercial hives in South Dakota and California’s Central Valley.

    To learn more about how the parasitic fly affects the bees’ behavior, the scientists have built a system to track the movements of infected bees in and out of a hive. cheap fjallraven kanken Each bee has a set of tiny radio frequency trackers — each no bigger than a fleck of glitter — attached to the top of its thorax. Tennis Nike The bees leave and return to the hive through a small tube outfitted with dual laser readers that interact with the individual trackers.

    Knowing exactly when bees leave–and whether they come back–is important for understanding how and when the parasites might cause the bees to abandon their hives. The original study found bees disoriented and dying at night, for instance, but the researchers aren’t sure whether the infected bees only leave their hives to fly in the dark. adidas cloudfoam hombre The researchers hope to capitalize on the interest in the bees with a citizen science project called ZomBee Watch.

    ZomBee Watch has three main goals. nike air max nederland 1. To determine where in North America the Zombie Fly Apocephalus borealis is parasitizing honey bees. Under Armour Curry One 2. To determine how often honey bees leave their hives at night, even if they are not parasitized by the Zombie Fly. 3. To engage citizen scientists in making a significant contribution to knowledge about honey bees and to become better observers of nature. fjallraven kanken mochilas If you live in the United States, they need your help finding out where honey bees are being parasitized by the Zombie Fly and how big a threat the fly is to honey bees. So far, the Zombie Fly has been found parasitizing honey bees in California and South Dakota.

    The Science Behind Ancient Honey

    In 1905 when archaeologist James Quibell uncovered the tomb of Yuya and Tjuya, the parents of 18th dynasty Egyptian Queen Tiye, who was Great Royal Wife of the Egyptian pharaoh Amenhotep III, among the items he discovered was a jar of honey. It was noted as still being liquid, and even still preserving its characteristic scent, despite being 3,300 years old. Stephen Piscotty Authentic Jersey

    So how can honey remain perfectly edible for thousands upon thousands of years, seemingly without an expiry date? The Smithsonian Magazine endeavoured to find out, and came up with a very interesting – and very complex – answer. asics gel pulse 7 męskie It all boils down to the sugar in the honey, sugar that contains very little water in its natural state, therefore providing an impossible environment for any external bacteria to live in.

    As Amina Harris, executive director of the Honey and Pollination Center at the Robert Mondavi Institute at Univeristy of California explains;

    Honey in its natural form is very low moisture. San Antonio Spurs Very few bacteria or microorganisms can survive in an environment like that, they just die. They’re smothered by it, essentially.

    It has a pH that falls between 3 and 4.5, approximately, and that acid will kill off almost anything that wants to grow there.

    So what is it that honey bees do to the honey that makes it so apparently everlasting? The answer is in the nectar. sac kanken pas cher This first material collected by bees to make honey is naturally very high in water–anywhere from 60-80%. Canotte Los Angeles Clippers But through the process of making honey, the bees play a large part in removing much of this moisture by flapping their wings to literally dry out the nectar. Asics Gel Lyte 5 damskie On top of the behavior, the chemical makeup of a bee’s stomach also plays a large part in honey’s resilience. Bees have an enzyme in their stomachs called glucose oxidase. New Balance 530 męskie When the bees regurgitate the nectar from their mouths into the combs to make honey, this enzyme mixes with the nectar, breaking it down into two by-products: gluconic acid and hydrogen peroxide. Then hydrogen peroxide goes in to work against all other organisms that could possibly grow.

    A jar of honey’s seal, it turns out, is the final factor that’s key to honey’s long shelf life, as exemplified by the storied millennia-old Egyptian specimens. C.J. Mosley Ravens Jerseys As Harris explains, ”As long as the lid stays on it and no water is added to it, honey will not go bad.

  • Nike Air Max 2017 Dames
  • As soon as you add water to it, it may go bad. Or if you open the lid, it may get more water in it and it may go bad.”

    We’re assuming by “bad” Harris means “ready to spread on our toast or have in our tea”. Adidas buty sklep We estimate that since our Raw & Unheated Honey is as pure as honey can get, with as little processing as possible, this is the honey in our range most likely to be able to retain all its goodness for the longest.

    Pollinator-Friendly Plants Put To The Test For Science

    You hear a lot in the news about the decline of bees, and it’s the kind of issue that is easy to assume we can do nothing about. Asics Gel Quantum 360 Dames But one simple way people can help is via their gardens, by growing ornamental plants that are also attractive to flower-visiting insects. fjallraven kanken pas cher Although individual gardens are relatively small, collectively they comprise a substantial area. If public parks can get in on the act then the collective positive effects could be potentially staggering.

    Which plant varieties are attractive to flower-visiting insects? Given the great public interest, many lists of recommended plants have recently been produced. For example, in 2011, the UK’s Royal Horticultural Society produced a Perfect for Pollinators list. But where did this information come from? On closer inspection, it appears that these lists are based largely on personal experiences, opinions and anecdotes.

    Now a study by the University of Sussex researchers has attempted to put these recommendations on a firmer scientific footing. Air Jordan 2 Retro Scientists planted an experimental garden of summer-flowering garden plants on the university campus. Asics Gel lyte 3 Heren Thirty-two varieties were compared, each in two patches of 1×1m, in 2011 and 2012. fjällräven kånken Laptop 13 All varieties were easy to purchase and considered attractive to humans. Throughout both summers they made repeated counts of the numbers of insects on each patch. As they were counted the insects were also identified into nine categories (honey bee, 4 sub-categories of bumblebees, other bees, hoverflies, butterflies & moths, other insects).

    The most simple and striking result was that garden plants vary enormously, approximately 100-fold, in their attractiveness to insect flower-visitors. The most numerous insects by far were bees which comprised over 84% of all insects seen. Bumblebees 47-62% and honey bees 26-32% were the most numerous, with all other bees only 3-5%. nike free 5.0 hombre Their results did lead them to make some horticultural recommendations – Among honey bees, it seems borago (borage) came out on top, with origanum and a variety of different species of lavender also performing well, while overall the least attractive flowering plant for insects was the geranium. Colt McCoy – Texas Longhorns Marjoram, the researchers say, was probably the best “all-rounder”, attracting honey bees, bumble bees, other bees, hover flies, and butterflies. The team put a number of varieties of lavender to the test and found that highly bred hybrids, including some with novel colours – such as white or pink – that have been carefully bred into the plants proved the most attractive to insects.

     

     

    Dr Nigel Raine, from the Royal Holloway University of London, commented that with bee populations declining across the world, “we can all give bees a helping hand by planting the right flowers to give them the nectar and pollen they need. This study highlights that it’s important for bee-friendly gardeners to choose what you plant with care. Washington Wizards Gardeners and town planners should think carefully about the mixture of flowers they plant to ensure food is available for a wide range of bees and other important insect pollinators. asics gel stratus mujer It’s also important to cater for the needs of the rarer species and provide food at times when there might be fewer wild flowers in bloom.”

    Flowers attractive to bees and other insects are by and large also attractive to humans, and are no harder to grow or more expensive than any others. nike air max femme pas cher Therefore, choosing insect-attractive varieties over less attractive varieties is a zero cost option, and is a practical and simple way of helping bees and other flower-visiting insects in your own garden.

    Flight of the Bumblebee Studied for Science

    <span style="font-family: georgia, adidas chaussures femme palatino;”>Everyone is familiar with Rimsky-Korsakov’s famous interlude, however scientists from Harvard University have been studying an actual flight of the bumblebee in an effort to work out how the insects manage to remain steady in adverse weather conditions. Dr Sridhar Ravi filmed bumblebees as they flew in a wind tunnel allowing him and his team to control the airflow the bees had to contend with.

    <span style="font-family: georgia, Hogan Rebel palatino;”>Dr Ravi says “As we have all experienced, the wind speed and direction outdoors can be very variable, Nike Air Huarache [so] maintaining stable flight can be extremely challenging. The best micro air vehicles available today struggle to fly stably when there is even in a light breeze.”

    The team filmed the bees using high-speed cameras and replayed their flight in super slow motion, discovering how the insects adjusted their flight according to the airflow. Interestingly the footage revealed that the bees reduced their speed in unsteady winds, which seemed to allow them to expend more energy correcting their flight path.
    <span style="font-family: georgia, Billige Nike Sko palatino;”>“The bumblebees also seemed to be more susceptible to disturbances that pushed them sideways as opposed to up and down,” explained Dr Ravi. “The bees rolled considerably to change course and correct for the disturbances induced by the wind.”
