Milkweed Effect

In “Why Bees Are Disappearing,” Marla Spivak, an American entomologist, sheds light on the importance of bees in the pollination process as well as the decline in bee population. Spivak claims that “bees are the most important pollinators” because over one third of crop production across the world depends on bee pollination. However, bee populations have decreased since the end of World War II due to “multiple, interacting causes of death.” These causes are monocultures, pesticides, diseases, and flowerless landscapes, and they all pose a threat to plant diversity and food production. In order to prevent significant consequences and reverse impacts already made, Spivak encourages the audience to plant bee-friendly flowers without pesticide contamination so that bees, and therefore people, have access to better nutrition.

     Three different things are endangering the monarch butterfly. First, is the deforestation of Mexico. Through illegal logging of the forests and the thinning of the canopy the monarchs are left vulnerable to the elements including frost and freezing rain (Wexler, 2004). Second, is a genetically engineered corn. The corn is engineered to be insect

Furthermore bees specifically are particularly efficient with it being estimated that they are the sole pollinators for 50% of the approximate 80% of flowering plants which rely on insects for pollination (Bradbear, 2009). Their efficiency is further illustrated by the fact that a single colony containing 25,000 forager bees is able to pollinate 250 million flowers per day (Bradbear, 2009). As a result of this it can be seen that bees are hugely important as pollinators with many species of flower being completely dependent on them. Furthermore, the importance of bees extends beyond ecological diversity; certain types of bees are hugely important economically. In addition to pollinating a large variety of fruit and vegetables, bees produce Honey; together this results in them having an estimated value of service of £200m a year in the UK (National Audit Office (NAO), 2009). Overall it can be seen that bees are of significant importance that any decrease in population should be treated with concern, as a result of this a large quantity of research has been conducted into identifying possible

Sadly, the monarch butterflies are drastically decreasing due to the fact that the plant they need to survive, the milkweed plant, is slowly but surely diminishing.

Now that you have considered the different habitats in which the white clover is found and the factors

In this chapter the author stresses the importance of creatures that pollinate such as insects, birds,

The article begins with the statement of how falling population in bees will lead to a decline is crop production for the united states of America. This statement was announced at the American Association for the Advancement of Science or for short the AAAS. The United States relies on these bees for pollination as it is a big part of the economy bringing in over 3 billion dollars annually. It is mention how it is possible to reverse the decline in wild bees by habitat restoration. Bees are a huge part of the crop production in the united states which helps with the income and rotation of crops. In the article maps of troubled zones where placed in over 139 counties in agricultural regions of California, Pacific Northwest, the upper Midwest and Great Plains, West Texas, and Mississippi River Valley. All those places are known for their specialty crops such as almonds blueberries and apples. Those specialty crops

In the article, “Loss of Dung Beetles Puts Ecosystems in Deep Doo-Doo”, the author discusses the effects dung beetles have on an ecosystem, and how these beetles cohabitate in their surrounding areas. The study was conducted to determine how dung beetles function in their environment, and what happens to them as a result. Additionally, researchers wanted to figure out if there was any loss of biodiversity or destruction of the ecosystem within the beetle population. Researchers placed a population of beetles in two different areas to observe their behaviors. One of the areas was a hydroelectric dam in a tropical forest of Venezuela, and the other was a much smaller island. The results indicated that the larger bees left the smaller islands

I enjoyed my many years of participation in the Monarch Larvae Monitoring Project. Milkweed is the larvae's host plant. Unfortunately common milkweed (asclepias syriaca) has not done well

Fish and Wildlife Service compiled some data that shows that close to a billion monarch butterflies have disappeared since 1990. A leading reason into the disappearance is thought to be because of the use of certain pesticides and herbicides used on the milkweed plants, the primary life source for the butterfly. Farmers in the Midwest use the chemicals to destroy the milkweeds around their crops. They also use seeds that have been modified to tolerate herbicides but also destroys the milkweed plants. To counteract the loss, environmentalists urge creating Monarch Waystations, gardens that include the milkweed plants the caterpillars eat and the nectar plants they feed upon as adults. There are also two species closely related to the milkweed plant that the monarch may mistakenly use to lay eggs on, Cyanchum louisae and Cyanchum rassicum. The poisons from these plants kill the caterpillar once it begins to feed upon their leaves unlike the milkweed leaves that the caterpillar can tolerate. The monarch is also captured and killed by collectors to be placed on

2.-transition-habitat loss, climate change, poaching and farming, pollution- the reasons for the decrease ar that their milkweed plants are decreasing, the climate can cause them to migrate at wrong times which causes many casualties, the large usage of pesticides are killing them off fast, and pollution in the air can also cost them their life.

Bees are important pollinators of many plants in the ecosystem (2). Recently, the decline in the number of bees in North America and Europe has shifted the research focus of many ecologists towards pesticide use (2). The impacts of pesticides on bees and other pollinators can have a major influence on honey production and biodiversity.

Kotliar, N. B. (1999) and Koford, C. B. (1958) also reported in their studies that grass abundance and plant species richness

Though it wants deer weed to reproduce and thrive, the organization pushes for cultivation of a widespread gamut of native plants. Most of these plants have not needed pesticides or herbicides, which lowers chemical imbalances in the environment and further reduces decimation of organic life (Palos Verdes Peninsula Land Conservancy, 2011b). So PVPLC has not focused on a single species or a handful of flora and fauna. The group includes all native species that support the diversity of life in and around the coastal region. It also grows deer weed in its nursery because of the plant’s symbiotic relationship with the PVBB, which has been declared as one of the region’s “four at-risk species.” The others at risk are the El Segundo blue butterfly, the coastal California gnatcatcher and the cactus wren (Palos Verdes Peninsula Land Conservancy,

The worry that is surrounding the spread of the Zika virus is spreading throughout the United States as the first cases of Zika have been discovered. Yet, the preemptive measures to ward off the disease are having costly back lashes. Florida, along with many other states, has begun aerial spraying to kill off mosquitoes on contact. Yet, this has had a costly effect on another population in the area…bees. The Social Environmental Impact Assessment will evaluate the long lasting affect that aerial spraying may have on the bee population of Florida and subsequent wildlife and plant life.
