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 […]
Genetic and epigenetic relationships across evolutionary and ecological timescales in Icelandic stickleback
The ability of organisms to colonize or adapt to new and changing environments is of critical interest in biology, especially considering the threats and advances of human-induced environmental change. Certain traits may play a key role in determining population persistence or decline in the face of climate change, habitat fragmentation, and the like. In 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 […]
Revealing ancient hybridization’s role in diversification
Hybridization between closely related species is a rapidly emerging field of interest for evolutionary biologists, and the more scientists look for signals of hybridization (with ever fancier tools), the more we learn that hybridization is the norm rather than the exception (Payseur & Rieseberg 2016). While young species pairs tend to hybridize more readily than […]
