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.

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 ...

Seeing herbaria in a new light: leaf reflectance spectroscopy unlocks trait and classification modeling in plant biodiversity collections

open access: yesNew Phytologist, Volume 251, Issue 2, Page 811-829, July 2026.
Summary Reflectance spectroscopy is a rapid method for estimating traits and discriminating species. Spectral libraries from herbarium specimens represent an untapped resource for generating broad phenomic datasets across space, time, and taxa. We conducted a proof‐of‐concept study using trait data and spectra from herbarium specimens up to 179 yr old,

Unveiling the Global Linnean Shortfall in Leptophlebiidae (Ephemeroptera, Insecta): Historical Trends and Conservation Implications

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 6, June 2026.
ABSTRACT Understanding how many species exist on Earth is a fundamental yet challenging question in biology, with significant implications for biodiversity conservation. The Linnean shortfall, or the gap in taxonomic knowledge, remains a major obstacle, particularly in highly diverse groups like insects. This study focuses on the family Leptophlebiidae

BIODIVERSIDAD VEGETAL ASOCIADA A PLANTACIONES FORESTALES DE Pinus caribaea MORELET Y Eucalyptus pellita F. MUELL ESTABLECIDAS EN VILLANUEVA, CASANARE, COLOMBIA PLANT BIODIVERSITY ASSOCIATED TO FOREST PLANTATIONS WITH Pinus caribaea MORELET AND Eucalyptus pellita F. MUELL. ESTABLISHED IN VILLANUEVA, CASANARE, COLOMBIA

open access: yesRevista Facultad Nacional de Agronomía Medellín, 2012
Resumen. Se analizó en una plantación ubicada en el bosque húmedo tropical la posibilidad que tienen las especies nativas de formar un sotobosque bajo plantaciones de Pinus caribaea y Eucalyptus pellita. Se establecieron parcelas permanentes en las plantaciones por especie, edad y tratamiento silvicultural; parcelas similares se instauraron en bosque ...
