Dr. Melinda Smith leads CSU ecologists launch study on droughts, deluges and carbon cycles in grasslands.
A $1 million DOE-funded study will combine field experiments and computer modeling to assess how extreme weather patterns brought on by climate change impact grasslands.

Welcome to the Department of Biology at Colorado State University. Our internationally-recognized research and education programs focus on organisms, diving into mechanistic detail about how they work, or stepping back to consider how they interact with each other and with their environment.  From cells to the biosphere, we make discoveries about fundamental questions in Biology, and we use this new knowledge to make the world a better place.  CSU Biology is a place where everyone is welcome to indulge their curiosity about the living world.

Why do salamanders have junk DNA? CSU’s Rachel Mueller wants to know

Rachel Mueller, a professor in the Department of Biology at CSU, studies salamanders and their cellular makeup. She’s found an interesting quirk in these species’ evolutionary histories – they’re full of “junk” DNA. 

CSU study finds disease-carrying tick populations expanding into Colorado

The study, funded by Bay Area Lyme Foundation, showed that American dog ticks are present in 16 counties in Colorado where they were not previously identified by the Centers for Disease Control and Prevention.

Biologists unveil clues to evolutionary origins of brown-colored algae for health, biofuels research

Brown algae are brown because they have evolved a special set of pigments that absorb even more light for photosynthesis than green plants and green algae do.

CSU offers new clues to how plants retain healthy genomes, avoid mitochondrial disease

A new study sheds light on how plants, however rarely, experience mutations in their mitochondrial genomes. Unlike humans, plants are able to quickly fix these mutations and not pass them on to their progeny.
