Certain populations of threespine stickleback fish have evolved over time to resist tapeworms found in freshwater lakes, but this resistance comes at a cost. Biological Sciences Asst. Prof. Natalie ...

UC Berkeley scientists studying stickleback fish published new research suggesting that changes in gene regulation may underlie the evolution of body patterns in nature. Researchers found that ...

Advanced Inquiry Program (AIP) graduate Bonnie May '23 of Oceanside, California, asks us to consider the three-spined stickleback fish when restoring ecosystems. In ...

Across rows of floor-to-ceiling shelves in the basement room of the Harvard Museum of Comparative Zoology, mason jars labeled with scraps of paper are filled to the brim with silver, finger-sized fish ...

Lugging around a tapeworm that’s one-third your body weight can be a real drag. So threespine stickleback fish evolved resistance to tapeworms — but resistance has costs of its own, a team of ...

The stickleback fish, Gasterosteus aculeatus, is one of the most thoroughly studied organisms in the wild, and has been a particularly useful model for understanding variation in physiology, behavior, ...

Stickleback fish are able to adapt their vision to new environments in less than 10,000 years, a blink of the eye in evolutionary terms, according to new research by University of British Columbia ...

How do animals make decisions when faced with competing demands, and how have decision making processes evolved over time? In a recent publication in Biology Letters, Tina Barbasch, a postdoctoral ...

You're likely familiar with the idea of the sterile mule: a hybrid animal born of a horse and a donkey that is unable to breed. But what about a fertile mule whose teeth just aren't right for chewing ...
