Conserving the evolutionary history of birds

Conservation Biology, Volume 37, Issue 6, December 2023., 2023
Abstract In the midst of the sixth mass extinction, limited resources are forcing conservationists to prioritize which species and places will receive conservation action. Evolutionary distinctiveness measures the isolation of a species on its phylogenetic tree.

Does invasion by armored catfish shift trophic ecology of native fishes? Evidence from stable isotope analysis

Ecology, Volume 104, Issue 5, May 2023., 2023
Abstract Popular as aquarium fish, armored catfishes from South America (Pterygoplichthys spp.) have been introduced and become invasive in tropical and subtropical regions worldwide. These ecosystem engineers can deplete basal resources (e.g., periphyton and detritus), with potential negative effects for native fauna. We studied the trophic ecology of

Water use partitioning of native and non‐native tree species in riparian ecosystems under contrasting climatic conditions

Functional Ecology, Volume 36, Issue 10, Page 2480-2492, October 2022., 2022
Read the free Plain Language Summary for this article on the Journal blog. Abstract One of the suggested mechanisms behind the success of non‐native plants in recipient ecosystems is competition avoidance with natives by means of different resource‐use strategies, such as deeper water uptake under dry conditions.

A quantitative global review of species population monitoring

Conservation Biology, Volume 36, Issue 1, February 2022., 2022
Abstract Species monitoring, defined here as the repeated, systematic collection of data to detect long‐term changes in the populations of wild species, is a vital component of conservation practice and policy. We created a database of nearly 1200 schemes, ranging in start date from 1800 to 2018, to review spatial, temporal, taxonomic, and ...

Threats of illegal, unregulated, and unreported fishing to biodiversity and food security in the Republic of the Congo

Conservation Biology, Volume 35, Issue 5, Page 1463-1472, October 2021., 2021
Abstract Illegal, unregulated, and unreported (IUU) fishing poses a major threat to effective management of marine resources, affecting biodiversity and communities dependent on these coastal resources. Spatiotemporal patterns of industrial fisheries in developing countries are often poorly understood, and global efforts to describe spatial patterns of
