Phylogenomics and biogeography of the cleptoparasitic bee genus Triepeolus Robertson (Hymenoptera: Apidae), with a revised subgeneric classification of Triepeolus and its sister genus, Epeolus Latreille Filogenómica y biogeografía del género de abejas cleptoparásitas Triepeolus Robertson (Hymenoptera: Apidae), con una clasificación subgenérica revisada para Triepeolus y su género hermano, Epeolus Latreille

open access: yesSystematic Entomology, Volume 51, Issue 1, January‐March 2026.
A subgeneric classification is proposed for Triepeolus—the second‐largest genus of cleptoparasitic apid bees in the world—and its sister genus Epeolus, with support from a newly presented dated phylogeny. Phylogenomic analysis based on ultraconserved elements revealed strong support for the monophyly of Triepeolus, which diverged from Epeolus sometime ...

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

open access: yesBiotropica, 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).

The influence of hydrological seasonality and land use and cover on the relationship between dissolved organic carbon and carbon dioxide along a karst‐draining large tropical river

open access: yesLimnology and Oceanography, Volume 70, Issue 10, Page 2858-2871, October 2025.
Abstract The partial pressure of carbon dioxide (pCO2) in rivers is influenced by carbonate weathering, soil CO2, photosynthesis, and the mineralization of dissolved organic carbon (DOC). In tropical regions, elevated temperatures intensify these processes. However, their seasonal dynamics remain poorly understood in large karst‐draining rivers.

Range‐restricted species are poor proxies for functional diversity in the world's largest avifauna

open access: yesConservation Science and Practice, Volume 7, Issue 9, September 2025.
We assessed the relationship between avian taxonomic richness (four metrics) and functional diversity (three metrics) across Colombia, the country with the most bird species. We found total species richness and threatened species richness to be suitable proxies for both functional richness and evenness. Protecting the eastern slope of the Eastern Andes

Above‐ground competition by Nephrolepis brownii inhibits tree seedling recruitment in a tropical restoration experiment

open access: yesJournal of Applied Ecology, Volume 62, Issue 8, Page 1968-1979, August 2025.
As Nephrolepis brownii primarily interferes through above‐ground competition, management of above‐ground tissues may mitigate its impact. However, additional research on the efficacy of this management strategy and potential allelopathic traits is needed.

High extinction risk of the endemic tree flora in a hyper‐diverse region of the Amazon

open access: yesPLANTS, PEOPLE, PLANET, Volume 7, Issue 4, Page 998-1010, July 2025.
The rapid global loss of biodiversity, especially in the Neotropics, underscores the need to understand how deforestation impacts endemic plant species' extinction risk and conservation status. Due to limited ranges and habitat specialization, endemics are particularly Vulnerable.

On the Lack of Domestic Dogs in Pre‐Columbian Lowland Amazonia and Their Deep History of Entanglements With Humans in South America

open access: yesThe Journal of Latin American and Caribbean Anthropology, Volume 30, Issue 2, June 2025.
ABSTRACT Data from archaeology, ethnography, and ethnohistory document entanglements of dogs among South American Indigenous societies during pre‐Columbian and colonial times. The prolific presence and uses of dogs in the Central Andes and in parts of the Paraná Basin, Patagonia, and Circum‐Caribbean regions contrast with the conspicuous lack of ...
