Mutational load and adaptive variation are shaped by climate and species range dynamics in Vitis arizonica

New Phytologist, Volume 247, Issue 2, Page 998-1014, July 2025.
Summary Genetic load can reduce fitness and hinder adaptation. While its genetic underpinnings are well established, the influence of environmental variation on genetic load is less well characterized, as is the relationship between genetic load and putatively adaptive genetic variation.

Experimental Drought Suppresses Amphibian Pathogen Yet Intensifies Transmission and Disrupts Protective Skin Microbiome

Global Change Biology, Volume 31, Issue 6, June 2025.
This study used ecologically realistic enclosures with pumpkin toadlets to simulate short‐term drought conditions in Brazil's Atlantic Forest. Drought reduced the overall levels of a harmful amphibian fungus, but it also disrupted their protective skin‐associated bacteria and caused the toadlets to cluster in wet areas of the enclosures, which ...

Pyraloid Moth Assemblages Exhibit Complex Morphological Patterns Across an Ecuadorian Mountainous Forest

Biotropica, Volume 57, Issue 3, May 2025.
In this study, we examined how morphological traits and species diversity of Pyraloidea moths vary with temperature and vegetation cover along an Andean rainforest gradient in Ecuador. Using 4161 individuals (212 species) and cross‐validating with a larger dataset of 10,337 individuals (749 morpho‐species), we found a near‐linear decrease in diversity ...

Influence of the distance between projectiles in simultaneous multiple impacts on CFRP laminates

Polymer Composites, Volume 45, Issue 18, Page 17075-17087, 20 December 2024.
The influence of the distance between projectiles in the simultaneous multiple impact phenomenon on CFRP laminate plates was investigated using a numerical model. Abstract Composite structures in the aerospace and railway industries frequently experience single or multiple low‐ or high‐velocity impacts.

Constructal design aplicado a placas com furos elípticos sob flambagem

Vetor, 2013
Placas são elementos amplamente empregados na engenharia estrutural. Em muitas situações é necessária a existência de perfurações nestas placas. Sabe-se ainda que elementos estruturais esbeltos submetidos a cargas de compressão axial podem falhar de ...

Do sexual differences in life strategies make male lizards more susceptible to parasite infection?

Journal of Animal Ecology, Volume 93, Issue 9, Page 1338-1350, September 2024.
Sexual dimorphism in coadaptive host–parasite relationships are poorly understand. The comparative nature of the presented studied as well as the generalisation of the results for the geographic region sampled makes this study of general interest of ecologists, evolutionary biologists, physiologist and parasitologist, among others.

A nationwide assessment of microplastic abundance in agricultural soils: The influence of plastic crop covers within the United Kingdom

PLANTS, PEOPLE, PLANET, Volume 6, Issue 2, Page 304-314, March 2024.
Agricultural soils are substantial receptors of plastic pollution. Plastic crop covers, a facet of agriplastics, may represent an important contribution to microplastic load in agricultural soils. The authors present a nationwide study of agricultural soils in the United Kingdom, comparing microplastic load between sites where plastic crop covers are ...
