After a forest fire or other aspect that would bring an area back in succession, bees can help bring back the vegetation in that area faster by pollinating, than natural pollination would. In many areas, bees have been seen to protect new tree sapling from getting eaten by deer and other animals. Since they are such good pollinators, they provide other food sources for many different species so they don't have to eat the saplings. Honeybees have always been biological indicators, in other words, honeybee health helps us see the general health of the environment. A reduction in honeybees could surprisngly be positive because as stated before they are not native to North America and the native species could thrive because of this. Bees are vital to nature for their pollination rituals; it is estimated that one third of the human food supply depends on insect pollination, most of which is accomplished by bees. Bees either focus on gathering nectar or on gathering pollen depending on demand. Honeybees are not native to the U.S. and were brought here from Europe by the early settlers. Bees can collect up to 66 Ibs. of pollen per year per hive.This accounts for 80% of insect pollination. Over the last year one third of the world's bee population has disappeared. Over the next twenty years scientists speculate that bees will disappear altogether. This disappearance began in the United States and quickly made its way to Europe, Latin America, and Asia. Concern is rightly placed on their disappearance: scientists conclude that along with their disappearance pollination will cease to occur; resulting in the disappearance of plants and possibly threatening mankind. A large array of government officials met in October 2012 to outline the future US policy on bees. Pathogens have detrimental effects on bees, and we must do more research on how they contract disease and how to stop them. The EPA is using regulatory actions to protect them. creating warning labels on pesticides about when not to use them to avoid damaging bees. Working in joint agency projects to make the environment more suitable for bees. researching the issues the bees are facing and publishing online how dangerous the different pesticides are to try to be able to find a way to combat these problems. Without bees, life on earth would be much different and conditions for the development of humans may not have existed. Bees are pollinators that are important to our food chain. A third of all food we eat today would not be around without the help of bees. The importance of these native pollinators in the reproduction of flowering plants is just beginning to be understood. The flowers of different plant species often require different behavior by collecting bees. Importance of Bees Effects on Industry and Consumers The 3 Castes: Bibliography By: Madison Kazar, Ryan Pearce, Andrew McDonald, James Nicolucci, Anthony Schiano Counterpoints on the issue There are three castes of honey bees: The Queen: One queen in each hive which produces all eggs. The queen bee can live between 3-5 years and lays up to 2000 eggs per day. The Queen can lay up to 250,000 eggs per year and possibly more than a million in her lifetime. The second major function of a queen is producing pheromones that serve as a social “glue” unifying and helping to give individual identity to a bee colony. Workers: All workers are female but cannot reproduce. Nearly all bees in the hive are workers and get their name because they literally "work themselves to death". During the Winter months, workers live between 4-9 months and during the Summer only about 6 weeks. Interestingly, specific chores are assigned in sequential order consiting of construction workers, guards, nursemaids, and foragers to name a few. Drones: Their sole

Transcript: Honey bees are the only insects to make a human food. Honey bees in Danger!!! Honey bees are irreplaceable because no amount of human work can match the pollinating power of just a few hives. Muhammad Ali attributed all the honey he ate to the reason why he could "Sting like a bee." Prezi by: Courtney, Faryal, Jesse, and Summer. This means if the Bees are healthy, the environment is healthy. The same is true about the inverse. Most vegetables. Collony Collapse Disorder or CCD is a problem that many people blame on the usage of pesticides. Bees communicate by dancing certain ways. But direct human threats such as toxins are not the Honey Bees only problem. Bees Fertilize flowers, while flowers provide bees with necture for making honey! Bees are being helped! Nuts. Bee Pollination Fun Facts: The more Bees are helped the better the environment in a whole will be because Bees are a keystone indicator. Bee venom has shown to be a good treatment for Arthritis. As for Humans, Honey Bees are used for 30% of all crops that we consume. Bees will only fly to one species of flower per trip out of the hive. Efforts are being made to create more diverse crops in a single area. This will help the bee have more options when looking for necture. Bees never sleep. The Honey bee, in the area that it lives, pollinates up to 80% of all plants. Most fruits. These crops include.... Bees collect 66 pounds of pollen per year per hive. On average there are 17 different types of pesticides in a bee collony at one time. Body temperature stays at a constant 92-93 degrees F. regardless of surrounding temperature. Bees and Flowers have a mutualistic relationship. One ounce of honey has enough energy for a bee to fly around the world.

Transcript: The World Through the Eyes of a Honey Bee *honeybee is passive and will only sting when provoked or forced to defend the hive* How Do Their Eyes Work? Honey bees have COMPOUND EYES: Hundreds of SINGLE eyes next to each other ...each with its own lens....and each looking in a different direction! This does not mean, however, that the bee sees lots of little pictures,: each lens sees contributes to the overall image perceived by the compound eye. bees have a complex way of communicating to each other... their language is based upon characteristic dances, odor, and taste perception The language dance performed within a colony is based on the hive's relation to the sun For example: A dance straight up on the comb's vertical axis means towards the sun; to theright, means so many degrees to the right of the sun; and to the left, so many degrees to the left of the sun. A rapid dance means a short distance; a slower dance means increased distance. The bees do not actually HAVE to see the sun: they can perceive and interpret direction from the polarized light they receive from the sky they can also spot the food source through ODOR ASSOCIATION Worker bees respond to an intruder’s actions by secreting an alarm pheromone which acts as an odor signal to alert other workers When a bee stings, it is “marking” the surface with a STING PHEROMONE This results into a group stinging, of the intruder. When a honey bee stings, a barbere stringer remains in the victim. The stringer contains poison. Once they sting something, it will die shortly afterwards. Honey bees sting to defend their colony The Life of a Honey Bee... Yes, they sting. Let me tell you why. Let's Take a Look at How Honey Bees View the World... DEPENDS GREATLY ON SOCIAL STRUCTURE. There are three castes of honey bees: - Queens,which produce eggs - Drones or males, which mate with new queens and have no stinge - Workers, which are all non-reproducing females DUTIES: - the queen lays eggs singly in cells of the hive. - Larvae hatch from eggs in three to four days. - It is the job of the worker bees to feed and develop the larvae through stages The Hierachy: - Only one queen is usually present in a hive - New virgin queens develop in enlarged cells and get fed royal jelly by workers - When the existing queen dies or ages: a new queen is raised by the worker bees. The virgin queen takes several nuptial flights (mates with the drones) and starts laying eggs in the hive. Lifespan: - QUEENS usually live for three or four years - DRONES usually die during mating or they get expelled from the hive before hibernation - WORKERS die in 3 week in the summer and a few months in the winter how do they communicate?

Transcript: Stakeholder: Bees & The Environment (Maureen) General Bee Facts Bees feed on nectar and pollen Social vs. Solitary Bees Colonies are comprised of mostly workers Workers are females that are infertile because diet during development was insufficient to become a queen Bee colonies are often referred to as a "superorganism" Dependent on each other and don't last long outside colony Overall, bees are non-aggressive and only sting to protect the colony Foraging bees (ones seen at flowers) don't attack Honeybees die after using stinger once Bees in Colorado 946 documented bee species in our state More than all of the eastern half of the U.S. combined Jefferson County alone has 200+ species of bees Honeybee is not native to U.S. Purposefully introduced from Europe in 1600's What is killing the bees? Pesticides and Stress Virus Israeli Acute Paralysis Virus (IAPV) Transmitted by the Varroa mite Wasp control (Humans) Traps and insecticides Bees & the Environment In the last 30 years, more studies have been done on bees affecting ecology Focused on conservation of rare plants Important to crop growth, because of pollination Some plants can only be pollinated by bees "Usually a honeybee can visit between 50-1000 flowers in one trip, which takes between 30 minutes to four hours. In Europe, a bee can make between seven and 14 trips a day. A colony with 25,000 forager bees, each making 10 trips a day, is able to pollinate 250 million flowers." -FAO Want to avoid this: Stakeholder: Citizens (Mallory) Health Approximately 4% of allergy sufferers have insect allergies as their primary allergy (bee/wasp stings and venomous ant bites). Each year nearly 100 Americans die due to insect allergies. Direct costs of allergies accounted for nearly $6 billion ($5.7 billion in medications and $300 million in office visits) Video (3:50): Economic The decline in bee populations affects not only honey production but billions of dollars worth of crops that depend on bees for pollination. This means no honey, almonds, etc. food supply. Certain food prices, such as honey, could increase for citizens. Decrease in gardens due to lack of pollination of flowers. Stakeholder: Farmers (Krista) Pesticide Use neonicotinoids (nicotine based) imidacloprid used to keep harmful bugs away Costs $8-$12 Billion Dollars Loss of Fresh Fruits and Vegetables Cattle and other Farm Animals Crops Affected What we are doing Crop Rotation Ease the life of the bees Add flowers and "forest" areas around farms Stakholder: The Government (Jim) A few possible causes: increased losses due to the invasive varroa mite (a pest of honeybees); new or emerging diseases such as Israeli Acute Paralysis virus and the gut parasite Nosema; pesticide poisoning through exposure to pesticides applied to crops or for in-hive insect or mite control; bee management stress; foraging habitat modification inadequate forage/poor nutrition and potential immune-suppressing stress on bees caused by one or a combination of factors identified above. What is the EPA up to? Survey Data Collect samples HYPOTHESIS driven research Mitigative/preventive measures No reliably proven common strains between colonies which collapse Reevaluating the chemical Clothianidin Stakeholder: Beekeepers (Abigail) Keeping bees Honey production Pollination For industrial beekeepers, bees are their income Organic Beekeeping Organic beekeepers tend to keep smaller quantity of beehives Bees kept because they are good for the environment Losses According to USDA 2010/2011 winter loss survey, 61% of beekeepers have experienced losses greater than 13% What can beekeepers do? Food supplements for bees Stresses to the bees French beekeepers protested against Bayer's production of pesticides Questions? Any general questions? Things to think about: 1. Is CCD a real problem? 2. If so, who's responsible for fixing it? The EPA? Civilians? Beekeepers? Why? 3. How does toxic consciousness relate to CCD? 4. Should environmental justice be involved? Why or why not? 5. What can you do to help prevent CCD? The Guardian: A Brief Introduction Bee Disappearances in Colorado Scientists and citizens have been noticing a disappearance of bees in Colorado Known as "Colony Collapse Disorder (CCD)" Bee keepers across the country have reported a quarter of the 2.4 million commercial colonies have been lost since fall 2006 Possible reasons for CCD are: Pesticides Viruses Humans Stress Stakeholders: Bees & the Environment, Civilians, Farmers, Government (EPA), and Beekeepers
