Assessing the evolutionary distinctiveness of a highly threatened plant group: The urgency to preserve a unique lineage of evolution in Brazil

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 4, Page 1223-1237, July 2026.
Brazil's diverse flora is under several threats, with many unique lineages facing extinction, particularly in biodiverse regions like the Cerrado and campo rupestre. This study sheds light on the conservation needs of Cambessedesia (Melastomataceae), an endemic genus with 95% of its species endangered, using an approach to rank and prioritise species ...

Digitising biological collections to advance National Species Inventories: A case study from the flora of Chile

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 4, Page 1210-1222, July 2026.
In response to Chile's public policy to establish a national biodiversity inventory and monitoring system, we launched the HerbarioDigital.cl portal. We have digitised over 120,000 specimens representing more than 3,900 species from two Chilean herbaria, integrating them through a curated local taxonomic index.

Exploring Costa Rica's fungal trends: Insights from digitized specimens

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 4, Page 1256-1274, July 2026.
Fungi are essential to tropical ecosystems but remain largely absent from conservation agendas. By analyzing over 78,000 fungal records from Costa Rica—a globally recognized biodiversity hotspot—this study reveals key patterns in fungal diversity, distribution, and seasonality.

Hummingbird interaction niche packing is influenced by species richness and resource availability in the southern tropical Andes

open access: yesFunctional Ecology, Volume 40, Issue 7, Page 2275-2285, July 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Niche partitioning is often considered an important mechanism promoting species co‐occurrence in species‐rich communities. As species richness increases, niche partitioning may lead to different niche structures, including increased packing of species niches when the ...

Integrating Megabarcoding and Metabarcoding to Unlock Diversity and Distribution Data Shortfalls in Dark Taxa

open access: yesMolecular Ecology Resources, Volume 26, Issue 5, July 2026.
ABSTRACT Persistent biodiversity data shortfalls undermine our capacity to detect species, map their distributions and characterize their spatial genetic structure, limiting robust biogeographic analyses and the development of effective conservation strategies.

Tropical Bee Assemblage Diversity Decreases With Elevation While Body Size Increases

open access: yesBiotropica, Volume 58, Issue 4, July 2026.
Photos of bee specimens collected in the Colombian Andes across a nearly 3000 m elevational cline. They are arranged to illustrate both the decline in richness with elevation and the increase in community average body size with elevation. ABSTRACT Elevation gradients are powerful drivers of changes in species composition, richness, and functional ...

Evolution of Crematogaster sordidula (Hymenoptera, Formicidae) Ants in the Mediterranean Region During Plio‐Pleistocene Climatic Changes

open access: yesZoologica Scripta, Volume 55, Issue 4, Page 615-638, July 2026.
ABSTRACT Understanding insect responses to global climate change involves identifying strategies used during past climate oscillations. Phylogeography offers a powerful framework to unravel how historical climatic and geological events have shaped the spatial genetic patterns of species, providing critical insights into evolutionary processes, whereas ...

Impacts of Deforestation‐Driven Rainfall Reductions on Amazonia Forest Stability

open access: yesGeophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract The stability of Amazonian vegetation is strongly influenced by land–atmosphere feedbacks. It has been hypothesized that deforestation‐induced precipitation decline may lead to widespread forest decline across the entire basin. Using a moisture‐tracking model, we quantify how deforestation across South America alters downwind rainfall and ...
