Introduction:
Anoles are the largest and diverse group of lizards found in America. It is the most common topics for ecology and evolution studies. The two species Anolis carolinensis and the A. sagrei compete with each other and are aggressive. The species of anoles have a strong association of height and structure of toe pads, which the lizards use to climb. The researchers found that habitat of the lizards affected the evolution in the lizards.
When the A. sagrei was introduced on the islands the changes were seen. The islands, which did not support the A. sagrei and only had A. carolinensis did not see any changes. The researchers then collected samples of each type and also raised an offspring of lizard in the controlled environment and they researched about the differences in the genetic basis.

- WRITE ABOUT A THEME: INTERACTIONS In Batesianmimicry, a palatable species gains protection by mimickingan unpalatable one. Imagine that individuals of a palatable,brightly colored fly species are blown to three remote islands.The first island has no predators of that species; the second haspredators but no similarly colored, unpalatable species; and thethird has both predators and a similarly colored, unpalatablespecies. In a short essay (100–150 words), predict what mighthappen to the coloration of the palatable species on each islandthrough time if coloration is a genetically controlled trait.Explain your predictionsarrow_forwardity of 5000 trout.

Then, revise the model to consider harvesting the whales as a percentage of rM. Give various values for this percentage that lead to extinction and other values that lead to in- creases in the population. Estimate the maximum sustainable yield, or the percentage of rM that gives a constant population in the long term (Zill 2013). roto of 1500 m²/day clearing thearrow_forwardMimicry of yellowjacket wasps by clearwing moths is an example of a harmless species resembling a dangerous one.

- Predation is an interaction between two species best described how? One species benefits from the interaction at a cost to the other species. Both species benefit from the interaction. One species benefits from the interaction, and the other is unaffected. Neither species benefit from the interaction.arrow_forward. According to the video and the background information, what are the effects (direct and indirect) that elephants have on acacias? (Select all that apply.) Elephants can feed on and destroy individual acacia trees not protected by ants. Browsing by elephants induces the acacias to provide food and shelter to the ants. Loss of browsing by elephants eventually leads to the decrease of ant colonization of acacias. Reduced nutritional and physical support of ants by acacias due to loss of browsing by elephants allows other ant species and stem-boring beetles to inhabit the trees. video link : https://www.youtube.com/watch?v=s3blzcbll7Q&t=293sarrow_forwardThe Atlantic cod population is of primary economic importance to fishingcommunities throughout the maritime provinces in Canada. Unfortunately, thispopulation has underwent an extreme collapse in recent years due to overfishing.Some argue, however, that the collapse of the cod population may actually beattributed to an increase in the population of harp seals, a known predator ofcod. One suggestion to help cod stocks recover is therefore to permit the huntingof harp seals on a large scale. Suggest and explain one potentially negativeconsequence of limiting the harp seal population.arrow_forward
