Explain why there have been such drastic population declines in the collard lizards of the Ozark Mountains. Tie in as many different concepts that you learned in the class.
Homework Answers
Ans: There have been such drastic population declines in the
collard lizards (Crotaphytus collaris) of the
Ozark Mountains because of the following factors-
Habitat loss due to suppression of wild fires
Lizards being cold - blooded, need the sunlight to become active. However in Ozark Mountains initially it was open and sunny with herbaceous plants, grasses and wild flowers which supported Collard Lizards to reproduce is now full of vegetation with high density of canopies which resulted in low temperature and less exposure to rocks and light.
The possible reason for the Habitat loss is suppression of wild fires in that area because of that, there is less surface activity for the lizards.

please thoroughly explain, thank you.
B. Consider the following scenario. A large population of lizards occupies an extensive range that is rela-tively uniform ecologically (i.e., in terms of climate and co- occurring species). At a certain point in time, the ancestral population becomes divided down the middle into two similar-sized portions by a barrier that completely prevents the movement of lizards between the descendent populations. Around the same time, a major flood occurs, and a small number of individuals are...

Question 10: Anolis lizards are a genus of closely-related lizards that have evolved into many different morphs on various Caribbean islands and surrounding mainlands. Harvard scientist Jonathan Losos has classified these morphs into 6 types that specialize on and appear to be adapted to different microhabitats organized along vertical space. For example, "twig" (specializing on twigs) lizards have short legs with a slender body, whereas "trunk-ground" lizards have long hind legs with stockier bodies. Interestingly, similar patterns of morph diversification...

. Find a recent news article from a major news outlet about a business scandal in the last year. Summarize the news story and provide a web link to the news story. Then connect two different class concepts that we learned about this semester to the story. In doing this, explain the class concept and then show how it connects to or is relevant to that particular story. For instance, a story just broke about Ford and a problem with...
