Artificial water points facilitate the spread of an invasive vertebrate in arid Australia [PDF]
, 2014 Summary: The spread of invasive species after their initial introduction is often facilitated by human actions. In some cases, invaders only become established in habitats where dominant native species have been displaced as a result of human actions or ...

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.

Ca2+-dependent changes in cyclic GMP levels are not correlated with opening and closing of the light-dependent permeability of toad photoreceptors. [PDF]
, 1982 We have measured the levels of 3',5'-guanosine monophosphate (cyclic GMP) in isolated retinas from toad to investigate their correlation to the opening and closing of the light-dependent permeability of photoreceptors. When Ca2+-induced changes in cyclic

Potential species distribution and richness of ixodidae ticks associated with wild vertebrates from Michoacán, Mexico [PDF]
, 2014 Ticks are regarded as the most relevant vectors of disease-causing pathogens in domestic and wild animals. The diversity of Ixodidae is known for a very small number of genera.

Osmotic Effects on Mitochondria from Two Species of Amphibian, Bufo marinus and Rana catesbeiana
, 1991 The effects ql ionic and/or osmotic change on skeletal muscle mitochondrial performance were investigated. Two substrates, pyruvate and glutamate, and variation in osmotic pressure from 205 to 360 mosm in KCl or mannitol/sucrose media had no effect on ...

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 ...

Time domains of the hypoxic ventilatory response in ectothermic vertebrates [PDF]
, 2011 Over a decade has passed since Powell et al. (Respir Physiol 112:123-134, 1998) described and defined the time domains of the hypoxic ventilatory response (HVR) in adult mammals.
