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.

Q&A with Boettcher Scholar and International Science and Engineering Fair participant Marissa Martinez

Marissa Martinez, a first-year biology student at CSU, recipient of the renowned Boettcher Scholarship and proud Hispanic student, arrived at CSU in the fall of 2023, bringing with her a wealth of cultural and scientific knowledge.

How can solar energy installations prioritize ecosystems?

Solar energy will be an important part of powering the future, and two CSU researchers have proposed a solution to make sure future installations are built with preserving our ecosystems in mind.

CSU biologists document genome-level climate adaptation in endangered bird species

A new study led by Colorado State University is one of the first to document climate adaptation at the genomic level in a wild population.

What deer mice can tell us about high-elevation pregnancies and fetal growth

CSU biologist Kate Wilsterman is working to understand how the physiology of pregnancy has evolved and diversified across mammals – in particular, she’s interested in species’ adaptive strategies for dealing with the effects of high elevations, where oxygen is less abundant.
