The questions "What are species?" and "How do we identify species ... In this page, you will learn about variation within gene pools, as well as the ways in which this variation can be an ...

Learners will understand that variations can occur within a species. Learners will understand that changes in the environment can affect a species’ ability to survive and reproduce. Show your class ...

The variation within a single species has produced differences as large as those between two separate species. Some critics of the theory of evolution argue that it doesn't convincingly explain ...

Anatomical and hydraulic traits can indirectly and directly measure the transport capacity of a root, respectively. Exploring variation in root traits along topological orders within species is key to ...

Extensive genetic variation is contained within a population of any species and is clearly visible in the domestic dog species, as shown in the photograph below. For example, if a mutation led to ...

I focus on variation in reproductive strategies within and between sexes, and among species, viewed in the context of population biology and evolutionary ecology. I combine field observation, ...
