Global Ecology and Conservation, 2020 In response to encountering abiotic extremes, many organisms exhibit stress responses as measured by levels of corticosterone and heat-shock protein (e.g., HSP70) in the blood. Such responses can enhance organismal viability.

Dynamic environments generate geographic fluctuations in population structure of an inland shorebird
Ecosphere, Volume 16, Issue 6, June 2025.Abstract Species distributions depend on fine‐scale ecological processes and population growth trajectories and are influenced by climate and weather changes. However, the characterization of inter‐population dynamics underlying the geographic distributions of migratory organisms remains challenging.

prioriactions: Multi‐action management planning in R
Methods in Ecology and Evolution, Volume 16, Issue 6, Page 1028-1039, June 2025.Abstract Designing effective conservation strategies requires deciding not only where to locate conservation actions (i.e. which territorial units should be priortized), but also which type actions should be deployed. For most of conservation planning contexts, deciding where and what to do usually yields a complex and computationally challenging ...

Population Estimate and Spatial Distribution of Capybaras in Lake Paranoá, Brasília, Brazil
Biotropica, Volume 57, Issue 3, May 2025.Understanding the dynamics of capybara populations living in urban environments is relevant, especially given the conflicts observed between the species and humans in these environments. Here, we investigated the hypothesis of overpopulation of the capybara in Lago Paranoá, a lake in a large neotropical city, Brasília, Brazil.

Population Genetics Meets Ecology: A Guide to Individual‐Based Simulations in Continuous Landscapes
Ecology and Evolution, Volume 15, Issue 4, April 2025.This paper aims to be a practical guide to spatial simulation, helping researchers to implement realistic and efficient spatial, individual‐based simulations and avoid common pitfalls. We explore how mating, reproduction, density‐dependent feedback, dispersal, spatial and temporal heterogeneity, and natural selection affect population dynamics and ...

Global Ecology and Conservation, 2020 The population dynamics of an alien species can be heterogeneous across a geographically widespread invasion– and thus, the effectiveness of alternative control methods can vary.

Is “cooling then freezing” a humane way to kill amphibians and reptiles?
Biology Open, 2015 What is the most humane way to kill amphibians and small reptiles that are used in research? Historically, such animals were often killed by cooling followed by freezing, but this method was outlawed by ethics committees because of concerns that ice ...
