A distributed large‐volume soil sampling approach to address spatial heterogeneity in eDNA data collection

Methods in Ecology and Evolution, Volume 17, Issue 6, Page 1726-1734, June 2026.
Abstract Soil sampling for eDNA is a useful approach to assess ecological communities in specific locations, such as comparing community composition across different site treatments. However, species' dispersal abilities and habitat selection, among many other factors, drive the uneven distribution of organisms across the landscape. Thus, to accurately

Landscape features predict broad‐scale seed rain patterns across fragments of the Brazilian Atlantic Forest

Journal of Ecology, Volume 114, Issue 5, May 2026.
Along with precipitation, forest cover emerges as a fundamental driver of alpha and beta diversity in the seed rain. This highlights the role of habitat amount at the landscape level over patch‐level features, like patch size, for seed dispersal. However, increased seed density can be related to higher dispersal rates in forest borders.

Unraveling the effects of wet and dry areas on carbon emissions in an intermittent Mediterranean stream

Limnology and Oceanography, Volume 71, Issue 3, March 2026.
Abstract Stream hydrological regimes are increasingly altered by water extraction, land‐use change, and climate change, leading to prolonged streambed desiccation in many regions. These alterations significantly impact biogeochemical processes within stream networks.

A Novel Sampling Protocol for Fruit‐Feeding Butterflies in Grasslands and Open Habitats

Austral Ecology, Volume 51, Issue 1, January 2026.
This study proposed a novel sampling protocol for fruit‐feeding butterflies in grasslands and open areas in the subtropical region. The new method involves the use of Van Someren‐Rydon bait traps placed on specific supports closer to the ground, aiming to capture the true diversity of butterflies in these habitats.

Pathogenicity and Protein Expression Analysis of Macrophomina pseudophaseolina in Cucumis melo

Journal of Phytopathology, Volume 173, Issue 6, November/December 2025.
ABSTRACT Melon is a major crop cultivated in the Brazilian Semiarid region. Several soilborne fungal pathogens cause root rot and vine decline (RRVD) in commercial production areas. This study evaluated the pathogenicity of Macrophomina pseudophaseolina isolates in melon accessions and characterised their differentially expressed protein profiles using
