Local woman on cam nude for free Colony collapse disorderColony collapse disorder CCD is the phenomenon that occurs when the majority of worker bees in a colony disappear and leave behind a queen plenty of food and a few nurse bees to care for the remaining immature bees. While such disappearances have occurred throughout the history of apiculture and were known by various names disappearing disease spring dwindle May disease autumn collapse and fall dwindle disease1 the syndrome was renamed colony collapse disorder in late 20062 in conjunction with a drastic rise in the number of disappearances of western honey bee Apis mellifera colonies in North America.3 European beekeepers observed similar phenomena in Belgium France the Netherlands Greece Italy Portugal and Spain4 Switzerland and Germany albeit to a lesser degree5 and the Northern Ireland Assembly received reports of a decline greater than 50.Colony collapse disorder causes significant economic losses because many agricultural crops worldwide are pollinated by western honey bees.

Free fuck local slut no sign up Facts About Bumblebees January 13 2017 1057pm ETMORECredit Dan Mullen via Flickr Creative Commons licenseBumblebees are large fuzzy insects with short stubby wings. They are larger than honeybees but they dont produce as much honey. However they are very important pollinators. Without them food wouldnt grow.Twothirds of the worlds crop species depend on animals to transfer pollen between male and female flower parts according to ecologist Rachel Winfree an assistant professor in the department of entomology at Rutgers University. Many animals are pollinators including birds bats and butterflies but theres no question that bees are the most important in most ecosystems she said in a 2009 article in National Wildlife magazine.While other animals pollinate bumblebees are particularly good at it. Their wings beat 130 times or more per second according to the National Wildlife Federation and the beating combined with their large bodies vibrates flowers until they release pollen which is called buzz pollination. Buzz pollination helps plants produce more fruit.SizeThere are over 255 species of bumblebees according to the Integrated Taxonomic Information System ITIS so bumblebee

Yupik Eskimos who hunt the gray whale in Alaska and 19th century commercial whalers who hunted the gray whale in Mexico have each called it devil fish because of its reputation for fighting back and overturning boats when attacked.Today gray whales are protected by law and tourists who view them at their breeding and calving grounds in Mexico regard them as friendly. The whales seem to be curious about these tourists and frequently swim up to their boats and allow the visitors to touch their barnaclecovered backs. The experience is thrilling and many people believe the whales enjoy it too.The gray whale has the reputation as another kind of fighter a fighter against the forces that would bring about its extinction. The species has fought its way back from the brink of extinction on two occasions. Like other large whales gray whales were commercially hunted and their numbers were reduced to just a few hundred at two different times.The eastern Pacific population of gray whales has made a remarkable recovery as a result of legal protection. In 1995 this population was removed from the endangered species list. Unfortunately other species of whales have not been able to recover as quickly as the eastern gray and most remain highly endangered.Range and StatusThe gray whales range for

I dont know about you but I like to eat. In factit might be my favorite thing to do. So when something comes to my awareness that might impend that favorite activity I pay attention.In January of 2017 the Rusty Patch Bumble Bee was listed on the Federal Endangered Species List. It is my hope that this article like all the articles on Keeping Backyard Bees can help spread awareness understanding and action to help this little bug make a comeback. Its not just our food supply that is in danger but the variety beauty and diversity of our wildlife that is at stake.Bumblebees are the most effective pollinators due to their size fuzzy exterior and messier ways of plopping down on pollen and getting it all over themselves. Because of this they are better able to spread pollen from flower to flower.Honeybees which seem to get the most attention are not even native to the United States and dont hold a candle to some of the other native species where pollination is concerned.There are however around 250 species of bumble bees in the world and 47 live here in North America.Bumblebees do better in northe

Free nline housewife sex cams Why It Matters an Endangered Species Classroom TopicWHY IT MATTERSShould it matter to humans that other life forms are disappearing Many people think so. Human populations depend on plants and animals for much of their food medicines clothing and shelter.Perhaps even more important intact ecosystems perform many vital functions like purifying the air filtering harmful substances out of water turning decayed matter into nutrients preventing erosion and flooding and moderating climate. It is not known how many species can be eliminated from an ecosystem without its functioning being impaired.It is likely that an ecosystem with more species is more stable than one that has lost some species. For example research has shown that grassland plots with a greater number of plant species are better able to withstand drought than those with less species diversity. This stability may well be important in the future as changes in precipitation brought on by global warming stress ecosystems.Some species are particularly important to the health of their ecosystems. These are called keystone species because like the center stone in an arch their removal can greatly affect the entire system.A classic example of the consequences of removing a keystone species occurred when fur hunters eliminated sea otters from some Pacific kelp beds. Otters eat sea
