Long-range transport of air pollutants increases the concentration of hazardous components of PM_2.5 in northern South America [PDF]

Atmospheric Chemistry and Physics
Long-range transport (LRT) of air pollutants from a range of sources can substantially enhance background pollution levels, especially in urbanized regions, which can exacerbate high-pollution episodes.

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.

Uncovering correlates of decline and critical refuges for a threatened terrestrial mammal

Conservation Biology, Volume 40, Issue 4, August 2026.
Abstract Globally, the geographic ranges of numerous species are contracting. Identifying spatiotemporal patterns of threat impact can illuminate why species decline in some parts of their range but persist in others. We developed a correlative approach to identify species’ response thresholds and locate ecological refuge areas associated with ...

Spiders in the mosaic: How habitat heterogeneity and structure drive local spider diversity in a Mediterranean forest

Ecological Entomology, Volume 51, Issue 4, Page 810-826, August 2026.
We assessed alpha‐ and beta‐diversity patterns of spiders across different forests and across vegetation layers (ground, shrub, low canopy) at local spatial scales across various Mediterranean forest types. Across forests, alpha‐diversity increased with habitat heterogeneity, which also drove beta‐diversity patterns across plots .
