Dispersal and delimitation: Phylogenomics of Connaraceae prompts revised generic delimitation in Cnestideae and reveals global biogeographic patterns

open access: yesTAXON, Volume 75, Issue 2, April 2026.
Abstract The tempo and mode of assembly of the world's most diverse, tropical floras remain poorly known. Evolutionary relationships within pantropical plant clades such as Connaraceae (Oxalidales, ca. 220 species) offer an opportunity to address this issue.

Use of species’ responses to cryptic anthropogenic disturbances for monitoring biodiversity outcomes in tropical forests

open access: yesConservation Biology, Volume 40, Issue 2, April 2026.
Abstract Measuring area‐based conservation outcomes in tropical forests is challenging due to cryptic human disturbances (e.g., hunting). As a result, comparative studies of management strategies providing quantitative outcomes remain scarce, especially in the Neotropics.

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

open access: yesEcosphere, 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.

How many cows are in the desert? Molecular phylogeny and species delimitation of the genus Gyriosomus (Coleoptera: Tenebrionidae: Pimeliinae) from the Atacama Desert

open access: yesSystematic Entomology, Volume 51, Issue 1, January‐March 2026.
The newly systematic rearrangement of Gyriosomus recognizes 9 clades, validates 21 taxonomical species and suggests 12 synonyms and 12 species candidates. Three taxonomical species were not evaluated. Polymorphisms, convergences and crypsis have been detected, and therefore morphology‐based taxonomy should be approached with caution. Ecological drivers
