Hidden Losses: Assessing the Risk of Coextinction Among Ectoparasitic Flies and Their Bat Host Species in Brazil

Animal Conservation, EarlyView.
The potential impact of bat species extinction on the number of their ectoparasitic fly species, based on interaction data for Brazil. As bat host species are removed over time, more connected species (green) would experience steeper declines and lead to greater ectoparasite losses when compared to a random extinction model (gray).

Impact of global change on the distribution of mountain mammals and birds

Conservation Biology, EarlyView.
Abstract Climate change and land‐use changes are key drivers of global biodiversity loss. Many species are shifting to higher elevations or latitudes in response to global warming, often encountering unfavorable land‐use conditions during the shift. These changes can lead to reduced range size and increased extinction risks, particularly for mountain ...

O efeito do tratamento térmico a 300 ºC na conectividade da estrutura de poros de argamassas de cimento Portland reforçadas por fibras de polipropileno The effect of heat-treatment at 300 ºC on pore structure connectivity of Portland cement mortars reinforced by polypropylene fibers

Cerâmica, 2012
A degradação térmica a 300 ºC de argamassas de cimento Portland reforçada por fibras de polipropileno foi investigada. Foi proposto um modelo computacional para a avaliação qualitativa da conectividade da estrutura de poros.

Ecology of reintroduced Rocky Mountain bighorn sheep in Dinosaur National Monument La Ecología de Borrego Cimarron de las Montañas Rocosas Reintroducido en el Monumento Nacional de Dinosaurio

Wildlife Monographs, Volume 223, Issue 1, August 2026.
We synthesized GPS telemetry, genetic, and pathogen data to evaluate metapopulation processes in a reintroduced Rocky Mountain bighorn sheep (Ovis canadensis canadensis) population in Dinosaur National Monument. We estimated subpopulation‐specific abundances and found 4 small subpopulations with high genetic diversity, partial connectivity, and ...

Conseqüências genéticas da regeneração natural de espécies arbóreas em área antrópica, AC, Brasil Genetic consequences of tree species natural regeneration in an anthropogenic area, Acre State, Brazil

Acta Botânica Brasílica, 2008
O cedro (Cedrela odorata L.) e o ipê-amarelo (Tabebuia serratifolia Nichols.) são espécies arbóreas tropicais economicamente valiosas e que têm sido ameaçadas pela exploração madeireira predatória e pela fragmentação florestal. Ambas apresentam dispersão

Wood anatomical trait correlations with hydraulic efficiency and safety in an aseasonal wet tropical forest

Functional Ecology, Volume 40, Issue 8, Page 2701-2717, August 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Xylem anatomy underpins the capacity of trees to transport water while avoiding hydraulic failure, shaping species performance and resilience to climate change. However, the specific ways anatomical traits underpin hydraulic trade‐offs in tropical forests remain debated.

Assessing differences among elasmobranch nurseries to aid conservation based on a genomics framework

Conservation Biology, Volume 40, Issue 4, August 2026.
Abstract Elasmobranch nurseries often differ in environmental conditions, demographics, and use patterns. These differences affect the distribution of genetic variation among nurseries. However, conservation and management strategies often fail to account for such differences because they are difficult to characterize.
