From the Field: An Exploration of Field Research

  About the blog author James Walts (He/Him/His) is an accelerated bachelor’s/master’s (ABM) student at the University of Alabama at Birmingham. He is currently studying the effects of phosphorylation of an essential to life protein (HP1a) in Drosophila melanogaster in Dr. Nicole Riddle’s lab. He is interested in exploring more aspects of research to better […]

Reproductive Isolation and the ‘Hockey Assist’ – How a shift to self-compatible mating systems can bring about reproductive isolation

The first steps in the process of speciation are a bit paradoxical when you think about it…how does one freely interbreeding species make the transition to two reproductively isolated, independent species? More specifically, how do intraspecific mating barriers become interspecific? And why even are there intraspecific mating barriers? Well, that last question is easier to […]

The difference 70 miles can make

Adapting to temperature is critical for any organism. Thus, many mammals, especially small, temperature-sensitive ones, have adaptations allowing them to modulate their metabolisms to adapt to their local winter temperatures, at an energetic cost (Chappell, 1980; Garcia-Elfring, Barrett, & Millien, 2019; Geiser & Ruf, 1995). The optimal metabolic modulation could be very precise, and would […]

Do marine species of a fin flock together?

In every biology textbook, Darwin’s finches remain a staple introduction to the concept of speciation and adaptive radiations.  Considered part of the tanager family, these fifteen species native to the Galapagos Islands evolved from a single ancestor 2 million years ago (Lamichhaney et al. 2015).  Since then, many examples of species flocks, or groups of […]
