Estimación de la riqueza de especies de Asteraceae mediante extrapolación a partir de datos de presencia-ausencia

Botanical Sciences, 2005
Se estimaron los patrones de riqueza en México de cuatro tribus de la familia Asteraceae del país que recientemente han sido revisadas (Mutisieae, Senecioneae, Tageteae y Vernonieae) mediante extrapolación, utilizando datos de las etiquetas de ejemplares de herbario.

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

PLANTS, 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.

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

Functional 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 ...

Mothbox and Mothbot: Automated light trap and data processing system for scalable insect monitoring

Methods in Ecology and Evolution, Volume 17, Issue 7, Page 2082-2091, July 2026.
Abstract Insects represent the most diverse group of organisms on Earth and comprise the majority of known species; yet they are seldom accounted for in large‐scale biodiversity monitoring systems and conservation planning. We have developed the Mothbox—an open source automated light trap that makes insect monitoring accessible to non‐specialists and ...

Tropical Bee Assemblage Diversity Decreases With Elevation While Body Size Increases

Biotropica, 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 ...

Riqueza florística y recambio de especies en la vertiente orinoquense de los Andes, Colombia

Colombia forestal, 2017
El mecanismo de neutralidad propone que la diversidad beta es controlada por limitaciones de dispersión y que la similitud florística está correlacionada con la distancia geográfica. En este trabajo se evaluó dicha hipótesis y se comparó la riqueza de bosques subandinos de la Orinoquía con otras vertientes en Colombia, Ecuador y Perú. Se usó una prueba

Is There Life After Death? The Role of Standing Dead Phorophytes in Supporting Tropical Epiphyte Diversity

Biotropica, Volume 58, Issue 4, July 2026.
ABSTRACT Global increases in tree mortality from climate change and land‐use are altering forest structures, impacting canopy‐dwelling plants like vascular epiphytes, which depend on host trees (phorophytes). When a phorophyte dies standing, it becomes a snag, the local substrate conditions change and microclimatic exposure may increase, particularly ...

Riqueza y diversidad de las especies reportadas de Gongora (Orchidaceae: Stanhopeinae) en Colombia

Biota Colombiana
Las orquídeas son un grupo taxonómico muy diverso, dentro del cual, las especies del género Gongora tienen una alta relevancia debido a su relación con las abejas Euglossini, importantes polinizadoras en el neotrópico. Con el fin de conocer aspectos de la biología como la riqueza y diversidad del grupo, se revisó material vegetal en herbarios y bases ...

Reef fish assemblages impacted by sponges overgrowing corals

Ecosphere, Volume 17, Issue 6, June 2026.
Abstract Numerous stressors are driving long‐term declines in coral cover on coral reefs, significantly impacting reef fish biodiversity and community structure. The benthic space made available by declining coral cover is often occupied by increases in other organisms, including macroalgae, encrusting ascidians, and sponges.
