Taking the bait: Developing a bait delivery system to target free‐ranging crocodiles and varanid lizards with a novel conservation strategy

Ecology and Evolution, 2022
In tropical Australia, conditioned taste aversion (CTA) can buffer vulnerable native predators from the invasion of a toxic prey species (cane toads, Rhinella marina).

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.

Resting respiratory behavior in minimally instrumented toads - effects of very long apneas on blood gases and pH

Brazilian Journal of Biology, 2003
Resting respiratory behavior of Bufo marinus in minimally instrumented toads is described for a period of 24 hours in which the animals are left undisturbed.

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 ...

Long‐Term Declines in Body Size of the Invasive Rusty Crayfish (Faxonius rusticus) in Temperate Lakes

Freshwater Biology, Volume 70, Issue 1, January 2025.
ABSTRACT Invasive species often experience phenotypic change during the invasion process. For example, many invasive species are larger in their non‐native than native ranges, but some invasive species experience body size declines with time since invasion.

Pest control by the public: Impact of hand-collecting on the abundance and demography of cane toads (Rhinella marina) at their southern invasion front in Australia

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.

A biological invasion impacts ecosystem services: cane toads change the rate of scavenging and the suite of scavengers

Ecosphere, 2021
By affecting the abundance of key native species, invasive taxa may disrupt ecosystem services. In Australia, large monitor lizards (Varanus spp.) play critical roles as scavengers and apex predators.
