The following mating behaviors were looked for during the observation: orienting, tapping, ‘singing’, licking, attempting copulation, copulation. Observations were recorded.…
The objective of the Isopods Lab was to figure out if the Pillbugs favored the wet environment or a dry environment. After reading the pre-lab report on Pillbugs, my hypothesis was that “If water is added to an Isopods environment, then the isopods will favor the wet environment.” By using two groups of Isopods, one group was put into a dry environment and the other had one drop of water into their dish. After ten minutes of observing the Isopods, the results showed that the Pill Bugs prefer the wet environment more. As time went on, the bugs in the wet environment survived longer than the Isopod in the dry environment.…
The Homarus americanus also known as the true lobster, the northern lobster, and the Maine lobster play a imperative role in the ecosystem. They are a ample source of food for America and all around the world because fishermen harvest such preponderant amounts lobster. Sometimes they are over fished so places such as the European Union, Canada, the U.S, and New Zealand are starting the manage the amount of lobsters harvested so that fishermen do not deplete the source. The reason they are so imperative is because lobsters are the cynosure of scarce fisheries all around the world and are frequently regional icons mainly because lobsters are some of the most researched animals on earth. Also research centers for lobsters have made enormous amounts…
The Effects of Phenotypes on Predatory Selection Pressure Faith Farmer BIOL 107-512 10/15/15 Introduction The purpose of this experiment is to evaluate how different phenotypes influence predation patterns in Dottus variegatus. In nature, observations of animals such as insects and predatory birds indicate that predators select against organisms with phenotypes that do not blend in with their environment. In this lab, dots and their colors represent the species Dottus variegatus and the different phenotypes.…
In many cases throughout the animal kingdom females run the mating game determining who they in turn want to mate with. One example of such depicted within the video was that of Barn Swallows. Barn swallows are sleek little song birds and are common throughout most of Central America. There was a theory that female Barn Swallows chose males with darker feathers more often to father their young. This was tested by darkening male Barn Swallow feathers with a marker and keeping track determining if they really indeed mate more then others.…
The results of our light and dark choice chamber experiment are ambiguous. The pillbugs appeared to be indifferent towards either the light or dark chambers. The pillbugs did not stay in one environment for a long period of time because they were active and constantly switched between the two habitats. This shows a lack of preference as well. Our data was fairly erratic as shown in figure 5, which is reflective of the pillbugs activity.…
Before an in depth analysis about the visual perceptions of both the common barn owl (Tyto alba) and the white-tailed deer (Odocoileus virgiriianus) can be provided, it is important for the reader to understand the environments of which these organisms can from. Unlike the Odocoileus, the Tyto genus are nocturnal, medium sized creatures with white-brown fur, and are found in almost all parts of the globe except Antarctica (Harris, 2002). In regards to the courtship ritual among these owls, it is the male species that must show-off their flight to the female by chasing after them (Harris, 2002). Once a couple is established, the Tyto owls tend to show fidelity and will not submit to another partner unless there is evidence that their original…
1. Interactions in which infants and their relationship partners together experience delight and other positive emotions, may create (or fail to create) expectations in that infant that people can experience positive feelings together. Some have argued that these expectations may come to act as an "internal working model" for later intimacy relating. Based upon your reading in this chapter (though you may also pull from latter chapters) do you agree or disagree? Explain.…
This article is interesting because it shows the biology and co-evolution between the male and female waterfowl. The male waterfowl has evolved to have forced copulation with the female. The male has a large corkscrew penis to efficiently penetrate and inseminate the female, but female evolved with the male to avoid unwanted insemination. The female can tighten her cloacal muscles to prevent fertilization of her eggs from an unwanted or undesirable male. The female's vagina has evolved to turn in the opposite direction of the male's penis and has dead end cavities inside.…
This predicted experimental design tested the hypothesis that male sea lions act differently alone then with a group of females. Results do support the hypothesis that male sea lions tend to interact more with each other compared to females. The data would inform the reader that these behaviors only would last for a short period. Sleeping and other aggressive behaviors would be at the same level. During the three days observing, there will be many times that there will be no display of various behaviors.…
Another behavior used is extra pair copulation which increases the likelihood of infant survival, since other males will be less likely to kill another's offspring if they think it may be their own. And as already established having more offspring increases the fitness of the…
Their two alternative hypotheses were: H1: They term it the “potentials-attract” hypothesis, “individuals relate self-perception on sex-specific indicators of reproductive potential to selectivity of mate preference for sex-specific indicators of reproductive potential in the opposite sex” (Buston and Emlen, 2003). H2: They term it the “likes-attract” hypothesis, “individuals relate self-perception on one trait to selectivity of mate preference in the same trait” (Buston and Emlen, 2003). They conducted this research on residents in Ithaca, New York. They were all heterosexual males and females, ages 18-24, there were 471 males and 507 females for a total of 978 participants. They had participants fill out the mate-preference survey which…
As a previously mention, various outlets have the power to influence our everyday life and it can also shape our courtship, marriage, and life choice. Mans are from mars women are from Venus. This ideology means that both sexes relationships communication and emotion are different. Nonetheless, when it comes to various outlets on masculinity; which is a combination of and biological sex factors socially defined between boys and men; these ads are puffery explicitly highlighted in Viagra pop-up ads on the Internet. Are they actually selling scams or are the selling us the need to dominate, attention and sex based on our emotional appeal.…
Introduction Oviposition is described as one of the final steps in reproduction in insects. It includes the deposition of mature eggs onto an object that is outside the body of the female insect (Saunders 2003). Where and how the organism oviposits depends on the behavioral aspects of different species. Another factor that can influence the oviposition of eggs involves the release of chemicals. The Diving Beetle chooses plants that have readily available food for their newly hatched young.…
Environmental-Dependent Sex Determination in Reptilians When we think of sex determination in organisms, we most often think of mitosis and the process of randomly receiving X and Y chromosomes from parent cells. This type of sex determination is known as genotypic sex determination (GSD), and it’s the most commonly found method of sex determination. However, this isn’t the only type of sex determination available to organisms. Some reptilians, for example, use environmental-dependent sex determination to determine the sex of newborns!…
