In attempting to determine whether wild hummingbirds are able to learn the refill schedules of flowers based on facilitated colour cues, Samuels, Hurly & Healy (2014) found that hummingbirds in the cued conditions were better and faster at discriminating between the refill intervals. They performed this study since there are not many studies which look at interval timing outside a controlled laboratory environment, as well as not many which remove other cues that may facilitate learning in the…
According to Atkins, Walmart had discussed its bee activities in the 2015 Global Responsibility Report stating: “We have been working hard to [lower the cost of our goods] in a way that also lowers the true cost to society … while reducing GHG emissions and preserving natural capital (oceans, forests…
Drosophila melanogaster has been studied in genetic research laboratories for almost a century. Because the fruit fly has a short lifespan, a simple genome, and is easily made to reproduce in captivity it is a prime candidate for genetic research. (Patterson, et al., 1943) The major behavioral response noted in the fruit flies is that they tended to group together in clusters, as opposed to venturing off on their own into different sectors. D. melanogaster are attracted to food and will mate…
What Females Want To a female barn swallow (Hirundo rustica), darker colors on the males will be the preferred mate choice. Females judge males by their reddish colored breast and belly feathers. The reddish feathers indicate a males quality, health, their ability to raise young, and is linked to a signal of high testosterone. Kevin McGraw, Cornell Ph.D. an assistant professor at Arizona State University in Tempe. Conducted studies of barns wallows finding that "Factors like ultra violet…
The authors of this paper recognized a lack of literature on the indirect effect predators have on prey, and pondered that this perceived risk might have a greater influence on prey behavior and life history than direct predation. By consistently removing any possibility for potential predators to reach the nests of a population of song sparrows, as well as playing recordings of potential predators, the authors reported a 40% decrease in the number of offspring produced. They also report a…
to animal extinction, If honey bees go exctinct we will greatly louse our food suplies and our population will begin to decend downward. We would end up being stictly put on a diet of grains weats and oats. Since thouse food products are not pollinated by honey bees. Thoughes with gluton free diets or have alergies to specific foods such as grains, may possibly die off. Adapting to such a disaster would be difficult. Many animals who relie on specific foods produced by honey bees will die off,…
1. Give examples of plant responses that are normally associated with animals. In the words of Dr., Hilker “They respond to tactile cues, they recognize different wavelengths of light, they listen to chemical signals, they can even talk through chemical signals. Touch, sight, hearing, speech. These are sensory modalities and abilities we normally think of as only being in animals,” 2. Describe the response of plants to the deposition of insect egg Once a plant has detected an insect, laying…
can help and hurt you. They help by spreading pollen to let plants reproduce in different areas. Bee’s also help by making honey for us to eat. They are harmful because they sting us and hurt us. Bees do a lot for us humans but they are becoming extinct. Honey bees in California are nearly extinct. The honey production went under half in just six years. The reason for the honey bees going extinct is because…
continent has been facing highest death rate of bees. The entire world is facing the decline in wild bee population due to several reasons. The reasons may vary among these continents because of the diversity in agricultural procedures. The Washington Post (2013) reported the causes of bees dying in the United States and the European countries. The European Union has recognized that the major cause of bee deaths in Europe is a specific class of pesticides such as neonicotinoids. The EU health…
In Dr Deborah Gordon tech talk, “How Ant Colonies Get Things Done” she presents her findings from studying a collection of ant colonies in New Mexico for the past 25 years. More specifically, she focus on the Red Carpenter ant species. While colonies of ants may look at first glance like simply a bunch of ants running around aimlessly, a closer and more careful look shows substantial social organization. A colony can solve problems unthinkable for individual ants, such as finding the shortest…
