The MexMAGIC population mixes native maize varieties from across Mexico to study functional genetic diversity. Summary Defining the genetic basis of local adaptation is a key goal of evolutionary biology and crop improvement. Theory predicts that when selective pressures follow differences in the environment, a cline will be established.

From Policy Neglect to Research Agenda: Administrative Burdens and Donor‐Conceived Mobilization
ABSTRACT Donor‐conceived adults are a growing population, mobilizing against the very regulatory arrangements that determined the terms into which they were conceived. In Canada and the United States, where donor conception remains persistently under‐regulated, gamete donation policy has historically prioritized the presumed needs of donors, recipient ...

ABSTRACT Understanding the origins and determinants of biological complexity requires integrating theoretical and empirical perspectives across the tree of life. The present work discusses a recent theoretical proposal suggesting that the emergence of eukaryotes can be understood as an algorithmic phase transition governed by universal scaling laws in ...

Estimating the total mortality of seabirds following a marine heat wave
Abstract Marine heat waves detrimentally affect a range of marine species, including seabirds, and are increasing in frequency and severity. When thousands of dead seabirds wash up on beaches, the public becomes concerned. However, the number of dead birds recorded on beaches is only a fraction of the total mortality; most birds perish at sea.

Abstract Monitoring wildlife health is essential for conservation and management, wildlife and livestock welfare, and public health in a One Health framework. Yet, wildlife health monitoring often requires long‐term fieldwork and intensive sampling, which can be costly or logistically challenging, especially for remote, rare, or elusive populations. To

Habitat and spatial trends of U.K. wintering waterbird populations over 50 years
Abstract The United Kingdom is an important wintering ground for millions of waterbirds. Most U.K. wintering waterbird populations increased between 1970 and the mid‐1990s, but declined thereafter. We examined U.K. population indices in 46 wintering waterbird species in two 25‐year periods, 1970–1994 and 1995–2019, to identify which waterbird groups ...
