Differential effects of agricultural expansion on wild bee taxonomic and functional diversity

Functional Ecology, Volume 40, Issue 4, Page 878-892, April 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Pollinators, especially bees, are in global decline, threatening biodiversity and food security. While intensive agriculture is a primary driver, its impact on bee functional diversity—particularly in the diverse Mediterranean region—remains understudied.

Secrets within stems: The cryptic Apodanthes caseariae (Apodanthaceae), a rare neotropical holoendoparasite

PLANTS, PEOPLE, PLANET, Volume 8, Issue 2, Page 385-400, March 2026.
Holoendoparasites are extremely rare plants that live entirely hidden inside their hosts, with only flowers and fruits visible. We studied Apodanthes caseariae, found in central and South America, parasitizing Casearia sylvestris. Little is known about its life cycle.

Breeding seasonality in Charadriiformes on the Andean Altiplano is influenced by rain and possibly flood risk

Ecosphere, Volume 17, Issue 2, February 2026.
Abstract The Andean Altiplano in South America represents a remarkable mountain ecosystem with unique wildlife. However, knowledge of breeding ecology for birds inhabiting Andean Altiplano is scarce, relying mostly on anecdotal records, and drivers of breeding phenology remain unexplored.

Integrating terrestrial and canopy laser scanning for comprehensive analysis of large old trees: Implications for single tree and biodiversity research

Remote Sensing in Ecology and Conservation, Volume 12, Issue 1, Page 5-20, February 2026.
Canopy laser scanning (CLS) enhances 3D measurements of large trees by lifting laser scanners into the canopy. Combining CLS with terrestrial laser scanning improves point cloud precision, reduces occlusion and enables detailed assessments of tree architecture and canopy biodiversity, opening new opportunities for forest ecology.

A new phylogeny of Anastrepha (Diptera: Tephritidae) based on nuclear loci obtained by phylogenomic methods

Systematic Entomology, Volume 51, Issue 1, January‐March 2026.
We present an extensive phylogenetic analysis, based on 293 nuclear loci and 728 individuals representing 237 species of Anastrepha, the largest and most economically important New World genus of Tephritidae. The analysis strongly supports the monophyly of most Anastrepha species groups, also revealing previously unknown relationships among species and

Ecologic Traits Analysis for Identifying Rodent Hosts for Arenavirus and Hepacivirus in the Americas

Biotropica, Volume 57, Issue 6, November 2025.
Over half of emerging human pathogens originate from wildlife, with rodents serving as key zoonotic hosts. This study used ecological trait‐based models to identify rodent traits associated with arenavirus and hepacivirus infections and detect potential host species across the Americas, our models achieve high predictive accuracy (AUC = 0.92–0.96).
