What role do pedigrees play in the preservation of the Galapagos giant tortoise?
About the author: Angie Bradley wrote this post as part of Dr. Stacy Krueger-Hadfield‘s Principles of Scientific Investigation course. Angie is a student in the Accelerated Bachelor’s/Master’s of Biology Program at UAB. In her time at university, Angie has become passionate about genetics, aging, and molecular biology. She hopes to one day attend dental school and […]
Parasite Tagging: A Surprising Identification Strategy in Ecological Research
Say you are studying a population of anadromous fish. These fish live in the ocean and swim upriver to spawn, with each fish returning to the river in which it hatched. The different rivers wind up containing separate subpopulations, as fish from different rivers never interbreed. How can these distinct subpopulations be recognized when the […]
It’s all about scale – evolution’s predictability (or lack thereof) across different spatial scales
In the late 20thcentury, a popular science communicator named Stephen Jay Gould asked a deceptively simple question: If we turned back the tape of life to the very beginning and allowed it to repeat from the beginning, would we arrive at a similar endpoint? In other words, how predictable and repeatable is evolution, and to […]
To band or not to band: what drives the expression of fashion accessories in female pipefish?
“Tale as old as time. Female chooses male. Male is large in size. Male has weaponry. Unsurprisingly! Male’s ornamentation. Male’s behavior. Female makes the eggs. Takes care of the young. Male and female roles.”1 But not all the time! 1Adapted from Disney’s “Beauty and the Beast” written by Howard Ashman As the female is usually […]
Studying the genetics of migration using hybrids from a migratory divide
Every spring, nature enthusiasts are excited for another bird migration made evident by the countless posts on social media noting rare warblers spotted in backyards and high species counts on birding trips. And the excitement is warranted, as migration is an amazing feat, both ubiquitous and complex, requiring coordination of numerous adaptations for the birds […]
What happens when hunting history, whale culture, genetics, and an international collaboration work towards a common goal?
Right whales were given their name because they were the rightwhales to hunt: they swim slowly near the ocean’s surface and make predictable annual migrations to easily accessible bays along the coast. They were hunted to near extinction before international protections were enacted in 1935. As the species recovered, researchers have acquired a myriad of […]
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 […]
Jumping genes help resolve obscure species relationships
Figuring out evolutionary relationships between species is hard enough when they diversified recently, but what if they rapidly diversified many millions of years ago? A group of baleen whales, the rorquals (Balaenopteridae), for example, diversified starting about 10.5 million years ago (Figure 1; Árnason et al. 2018). Within this group, the evolutionary relationship of the […]
