A century of theories of balancing selection
Biological Reviews, Volume 101, Issue 2, Page 804-825, April 2026.ABSTRACT Traits that affect organismal fitness are often highly genetically variable. This genetic variation is vital for populations to adapt to their environments, but it is also surprising given that nature – after all – ‘selects’ the best genotypes at the expense of those that fall short.

Ecosphere, Volume 17, Issue 3, March 2026.Abstract Long‐term studies of plant and animal populations are rare, particularly for long‐lived species with slow life histories. However, such studies are necessary to understand how population dynamics are affected by variation in vital rates. We used a large capture–recapture dataset spanning four decades (1983–2019) to estimate several population ...
