Antipoaching standards in onshore hydrocarbon concessions drawn from a Central African case study
Conservation Biology, Volume 31, Issue 3, Page 696-706, June 2017., 2017 Abstract Unsustainable hunting outside protected areas is threatening tropical biodiversity worldwide and requires conservationists to engage increasingly in antipoaching activities. Following the example of ecocertified logging companies, we argue that other extractive industries managing large concessions should engage in antipoaching activities as ...

Methods in Ecology and Evolution, Volume 16, Issue 6, Page 1136-1148, June 2025.Abstract One of the main limitations of phylogenetic comparative analyses is that associations between traits can only be interpreted as correlations. Here, we present a novel Bayesian structural equation model (PhyBaSE) which allows us to disentangle direct from indirect relationships among variables to propose potential causal hypotheses while ...

Sequential testing of complementary hypotheses about population density
Methods in Ecology and Evolution, Volume 16, Issue 6, Page 1228-1238, June 2025.Abstract Making inferences about population density is paramount in ecology and pest management for decision‐makers who often seek to determine how a population compares to a pre‐established static or dynamic threshold through sampling or monitoring. Sequential data analysis is appealing for monitoring and decision making as it is more cost‐efficient ...

Semina: Ciências Exatas e Tecnológicas, 2012 Para fazer inferências a respeito de uma população, métodos paramétricos são tradicionalmente utilizados para análises de dados amostrais supondo que estes são provenientes de populações normais, fato nem sempre ocorrido. Tal suposição induz muitas vezes

Methods in Ecology and Evolution, Volume 16, Issue 1, Page 170-182, January 2025.Abstract Harvest data have the potential to be used as an abundance index due to its widespread availability and long‐term collection across large geographical areas. However, challenges such as the lack of hunting effort information, varying data resolutions and reporting biases hinder its direct use as an abundance proxy.

An expert‐based system to predict population survival rate from health data
Conservation Biology, Volume 38, Issue 1, February 2024.Abstract Timely detection and understanding of causes for population decline are essential for effective wildlife management and conservation. Assessing trends in population size has been the standard approach, but we propose that monitoring population health could prove more effective.
