Brendan J. Pinto (he/him) received a PhD in August (2020) in the Gamble Lab. Currently he is a research associate of zoology at the Milwaukee Public Museum and a postdoctoral research fellow at the University of Texas at Austin in the Kirkpatrick Lab where they aim, among many other things, to disentangle the selective forces […]

Habitat Fragmentation of the Catfish Hemibagrus spilopterus: Dammed If We Do
About the author: Rose Ferguson wrote this post as part of Dr. Stacy Krueger-Hadfield‘s Principles of Scientific Investigation course. She is currently a dual Bachelor’s and Master’s student through the Accelerated Bachelor’s to Master’s program at UAB. She is planning on conducting research in Dr. Dustin Kemp’s lab beginning spring of 2021. With COVID-19 safety […]
Swiss army knife genetics: Does pleiotropy do all the adaptation job in Mimulus guttatus?
It is not a simple task to adapt to a new environment. An organism needs to acclimate itself to multiple new conditions, from differences in climate to novel parasites and predators awaiting for a newcomer. Such adaptive multitasking might take a long time to form at the genetic level and as a consequence delay 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 […]
A horse of a different color patterning mutation
Connecting genotypes to the complex phenotypes they produce is a fundamental goal of genetics. Variation in coat color pigmentation, partly due to the relative ease at which different patterns can be identified, is one of the best-characterized traits at the genetic level, with examples from sheep (Zhang et al., 2017), cattle (Li et al., 2016), […]
Is European bison really back?
Humans constantly interact with their environment. They modify habitats, transfer species from one place to another, domesticate some species while contributing to the extinction of others. To reverse the process of extinction, we’ve been reintroducing taxa since the 1800s. Reintroduction refers to the action of establishing self-sustaining and healthy populations of extinct or critically endangered […]
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 […]
Surviving cyanide – one path or many?
Cyanide is deadly – to most things. In high enough doses it blocks the body’s ability to create energy by interrupting cellular respiration. But even at non-lethal doses it has knock-on effects throughout the body. Despite this, a few mammals eat it regularly. In my last post, I described how I found multiple ways in […]
