A niche is loosely defined as an organism's role in its environment, which can include factors like, feeding preference, nesting behaviors, mating behaviors, method of obtaining prey, and local habitats. Considering Gause's law, conduct research on the California Red Legged Frog and the Northern Pacific TreeFrog (use wiki or other google search). Create a chart that compares the two with regard to their niche or their lifestyle that may explain how these two native frogs have evolved to coexist in the same ecosystem.

In spadefoot toads there are two forms of the tadpoles: omnivores and carnivores. Environmental factors such as population density, oxygen concentration, and availability of food determine which form any particular tadpole takes. Consider the situation below. A single pair of toads produces a fertilized group of eggs in a pond. The pond dries a bit creating two separate ponds, one is deep and the other is shallow. All the tadpoles in the deep pond become omnivores and all the tadpoles in the deep pond become carnivores. There is a heavy rain and the ponds become connected again and the two groups of tadpoles mix together. The carnivores eat most of the omnivores and more of the carnivores become adult toads This is an example of Group of answer choices A. natural selection and evolution B. evolution only C. natural selection only
Do the following two hypothesis supports their graphs? Explain. Figure 1: The hypothesis for novice vs. experienced foraging is that animals who have been foraging for ages should have a greater chance of survival than beginner foragers since they are more skilled and invest less time looking for food. Figure 2: The hypothesis behind the impact of Prey camouflage is that if animals, especially novice foragers, take too much time searching, they are visible to predators for long durations, providing a better chance to attack.
Read this quote from Charles Darwin (from Origin of Species). What is he describing? "Thus, I can understand how a flower and a bee might slowly become, either simultaneously or one after the other, modified and adapted to each other in the most perfect manner, by the continued preservation of all the individuals which presented slight deviations of structure mutually favorable to one another." An interaction network. A predator/prey cycle. O Coevolution. An obligate mutualism.
Conservation biologists have altered the evolution of salmon populations in captive-breeding programs. Wild female salmon tend to produce fewer large eggs because the large eggs contain more nutrients for the off spring, giving each individual a greater chance to survive. After just a few generations, however, captive-bred females now lay greater numbers of small eggs. Suggest a possible adaptive advantage for many small eggs in the captive-bred environment. What would you predict regarding the reproductive success of captive-bred females released in the wild?
Use the following information to answer the next question. When intraspecific competition occurs within a species, some individuals may have a competitive advantage over others. For example, some members of a plant species may be able to grow longer roots and absorb more water. These individuals have an advantage over other members of the species during periods of drought, and are able to survive to pass this competitive trait to their offspring. From the information given above, one can conclude that intraspecific competition promotes O inbreeding O natural selection O artificial selection speciation
An insecticide is sprayed that kills the grass blackberry bushes.explain how each of the other populations of organisms will be affected If all the trees in the area were cut down,the energy supply of which population would be most directly affected?How would an increase in the oriole population affect the ecosystem? How would an increase in grasshoppers affect the rabbit population? Using evidence from the food web,explain why it is called a food"web"
A defence mechanism is how the sea cucumber fires its internal organs at attackers. How would this defence mechanism have evolved over time due to pressure from predation and/or competition? Please explain in details.
Studies of two species of blackbirds showed that red-winged blackbirds establish nests mostly on the edges of marshes, but also extend throughout the marsh if yellow-headed blackbirds are absent. Yellow-headed blackbirds can nest only in the middle of marshes, regardless of the presence of red-winged blackbirds, because they require wetter habitat. Based on this, which of the following statements are true? Select all that apply. The realized niches of the two species differ. The fundamental niche of red-winged blackbirds is larger than its realized niche. The fundamental niche of red-winged blackbirds is larger than the fundamental niche of yellow-headed blackbirds. O The fundamental and the realized niches of red-winged blackbirds are the same. The fundamental and the realized niches of yellow-headed blackbirds are the same.
Please choose on of the best answer that fits for this multiple choice question, Thank you 1)Consider a predator-prey relationship between crabs and sea snails. The crabs use their claws and jaws to crack open the shells of the sea snails, and so, by the principle of natural selection, any snail with a thicker shell would have an advantage and thicker shells would become more abundant. This in turn would create a selective pressure for stronger claws and jaws in the crabs, which in turn would give a selective advantage to snails with even thicker shells. This type of interaction between predators and prey is an example of A)secondary succession B) coevolution C)primary succession D)symbiosis E)competition
Behavior influences how organisms experience the environment and thus patterns of natural selection on behavioral traits. Which of the following examples is consistent with this statement? Some lizards in complex tropical forests prefer to hang out on tree trunks and branches, rather than the ground substrate, which has resulted in selection for shorter relative limb length and toe pads that can cling to bark. Ground-burrowing mammals experience greater exposure to dust and increased selection on their respiratory system to filter these particulates. Specialist parasitoids only target a handful of different host/prey types, resulting in a predictable resource and less selection on the ability to learn new resources All of the above Imagine that scientists have just discovered a weird new marine tunicate at extreme depths of the ocean. They have a novel kind of neurotransmitter – maritonin – that binds to the “maritonin” receptor, which is permeable to negatively charged iodine ions…
