AMES, Iowa – The newly assembled genomes of 26 different genetic lines of corn illustrate the crop’s rich genetic diversity and could pave the way for a better understanding of what genetic mechanisms ...

In an article published in the Oct. 15 issue of Science, ecology and evolutionary biology professor Leonid Kruglyak ’87 and his collaborators — Sonja Skrovanek, a former researcher at the University’s ...

Differentiations in reproductive traits along climatic gradients can be substantial for a species to spread along a wide spatial range. We compared the reproductive effort allocated to first egg sacs ...

Plants rely on seed dispersal to track favorable habitats and escape unsuitable conditions in variable environments. One likely driver of phenotypic dispersal trait plasticity is the prevalence and ...

The genes of an organism play an important role in the development of characteristic traits. However, even the traits of genetically identical clones that grow up under the same environmental ...

Aim: To evaluate how environment and evolutionary history interact to influence global patterns of mammal trait diversity (a combination of 14 morphological and life-history traits). Location: The ...

Every ecosystem is shaped by billions of invisible battles: organisms competing for light, nutrients, space, or mates. These competitive interactions determine which species survive, how they evolve, ...

Behavioral geneticists study the genetic and environmental underpinnings of psychological and many other human traits. With a decades-long history and well-established research methods, the field has ...
