Sex chromosome transformation and the origin of a male-specific X chromosome in the creeping vole

Mystery solved? Chromosomal sex determination arises when an autosomal locus acquires a sex-determining function. In some taxa, this process occurs often. The XY system in mammals, however, has been evolutionarily stable across a wide array of species. Fifty years ago, a variation on this norm was described in the creeping vole (Microtus oregoni), but the...

$1 million project helps tribal nations adapt to climate change

UC Riverside ecologists are leading a $1 million plant protection project that will help Southern California’s tribal nations adapt to climate change. The goal of the project is to preserve plant species and ecosystems that enable the continuation of native tribal cultural practices. Currently, some of these species are facing threats including hotter temperatures, prolonged...

Professor’s own body becomes physiology lab during pandemic

Just call him Professor Guinea Pig. Adapting to remote learning this quarter, Professor Rich Cardullo is performing all the experiments for his human physiology laboratory course — on himself.

Rapidly Changing Flowering Times Imperil Pollinators

Plants are not simply flowering earlier with climate change, as is often reported in the media. Instead, they are responding to the changing climate in more complex ways. The rates at which communities of plants are shifting their flowering times differ greatly in different locations, even when those locations are only a couple hundred meters...

Katie Burnette Published in CourseSource

With the publishing of the Vision and Change report, we know it is best practice to include authentic research experiences in our undergraduate science lab classes. One big challenge in teaching so-called "wet lab" classes is figuring out a way to make sure students come to lab prepared to successfully complete their experiments. Molecular biology...

Guppies teach us why evolution happens

Guppies, a perennial pet store favorite, have helped a UC Riverside scientist unlock a key question about evolution: Do animals evolve in response to the risk of being eaten, or to the environment that they create in the absence of predators? Turns out, it’s the latter. David Reznick, a professor of biology at UC Riverside...

Ladies’ choice: What drives faster, flashier formation of new animal species

Evolution is actually a Sadie Hawkins dance, as new research shows females not only determine whether male animals develop bright colors, but also how fast new species develop. Research led by David Reznick, a UC Riverside biology professor, used fish often seen in pet stores, like guppies and swordtails, to test a hypothesis proposed by...

Snake attacking a kangaroo rat

High-speed videos capture how kangaroo rat escapes rattlesnake attack

Kangaroo rats are abundant and seemingly defenseless seed-eating rodents that have to contend with a host of nasty predators, including rattlesnakes — venomous pit vipers well known for their deadly, lightning-quick strikes. Research by a student-led team from UC Riverside, San Diego State University, and UC Davis now shows that desert kangaroo rats frequently foil...

Study finds natural selection favors cheaters

Mutualisms, which are interactions between members of different species that benefit both parties, are found everywhere — from exchanges between pollinators and the plants they pollinate, to symbiotic interactions between us and our beneficial microbes. Natural selection — the process whereby organisms better adapted to their environment tend to survive and produce more offspring —...
