Estimating the cumulative impact and zone of influence of anthropogenic features on biodiversity

Methods in Ecology and Evolution, Volume 14, Issue 9, Page 2362-2375, September 2023., 2023
Abstract The concept of cumulative impacts is widespread in policy documents, regulations and ecological studies, but quantification methods are still evolving. Infrastructure development usually takes place in landscapes with preexisting anthropogenic features. Typically, their impact is determined by computing the distance to the nearest feature only,

Forest conversion into pasture selects dung beetle traits at different biological scales depending on species pool composition

Ecology and Evolution, Volume 13, Issue 4, April 2023., 2023
Briefly, we assess the impacts of forest conversion on the functional diversity of dung beetles in two different regions of Brazil, considering in particular intraspecific variation. To do this we conducted standardized surveys in seven forest fragments and adjacent pastures for every region and measured fourteen traits in individuals collected in each

Which traits optimize plant benefits? Meta‐analysis on the effect of partner traits on the outcome of an ant–plant protective mutualism

Journal of Ecology, Volume 111, Issue 1, Page 263-275, January 2023., 2023
Our results highlight that the selective pressures and evolutionary routes in ant‐plant protective mutualisms may depend on the pool of traits exhibited by partner species. Although some studies have already reported some impact of species traits on the outcome of ant‐plant mutualisms, this is the first time that a generalization about the role of ...

Detecting and reducing heterogeneity of error in acoustic classification

Methods in Ecology and Evolution, Volume 13, Issue 11, Page 2559-2571, November 2022., 2022
Abstract Passive acoustic monitoring can be an effective method for monitoring species, allowing the assembly of large audio datasets, removing logistical constraints in data collection and reducing anthropogenic monitoring disturbances. However, the analysis of large acoustic datasets is challenging and fully automated machine learning processes are ...

The ecology and evolution of human‐wildlife cooperation

People and Nature, Volume 4, Issue 4, Page 841-855, August 2022., 2022
Abstract Human‐wildlife cooperation is a type of mutualism in which a human and a wild, free‐living animal actively coordinate their behaviour to achieve a common beneficial outcome. While other cooperative human‐animal interactions involving captive coercion or artificial selection (including domestication) have received extensive attention, we lack ...

Influence of hospital size on antimicrobial resistance and advantages of restricting antimicrobial use based on cumulative antibiograms in dogs with Staphylococcus pseudintermedius infections in Japan

Veterinary Dermatology, Volume 32, Issue 6, Page 668-e178, December 2021., 2021
Background Antimicrobial resistance in Staphylococcus pseudintermedius (SP) and the prevalence of meticillin‐resistant SP (MRSP) is increasing in dogs worldwide. Objectives To evaluate the influence of hospital size on antimicrobial resistance of SP and whether restricted use of antimicrobials based on antibiograms could reduce the identification of ...
