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…

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…

LET’S TAKE A LOOK AT CCD: COLONY COLLAPSE DISORDER POTENTIAL CAUSES FOR DISAPPEARING BEE COLONIES OVER THE LAST DECADE When you think of bees, you may first think of an annoyance. They want ruin your picnic, they might sting you, and many people are allergic to them. Take a closer look. Bees are a cornerstone in the production of many mass-produced foods. (Images from…

Evolution causes many changes in a species. Some species of animals develop thicker fur others have stronger muscles. Hummingbirds have to consume massive amounts of foods everyday in order to survive. One of their evolutionary traits is a mutated T1R1-T1R3 taste receptor. An experiment was conducted to test how hummingbirds detect sugars in nectar. The article “Evolution of sweet taste perception in hummingbirds by transformation of the ancestral umami receptor” (Maude W. Baldwin et al. science…

1 INTRODUCTION Drosophila Melanogaster, also known as the fruit fly, is a most valuable organism in biological research that has made significant contributions particularly in genetics and research. It is used as a model organism in research for several reasons viz. Easily handled, sexually dimorphic, cheap and easy to keep large numbers, care and culture requires little equipments and well understood because of its short life cycle of just two weeks and also Entire genome of drosophila…

Oak trees (genus Quercus) may possess a behavioral defense against acorn predators. Data collected from many oak species shows a common trend that several years of relatively low acorn production are followed by a year with an exceptionally large production of acorns. The term “mast” is used to refer to the amount of acorns produced per year, and the phrase “mast year” is used to describe the year in which acorn production is exceptionally high. Mast years seem to be synchronous within a given…
