A striking new species of Pristimantis (Anura: Terrana: Strabomantidae) of the northwestern foothills of the Andes of Ecuador

ACI Avances en Ciencias e Ingenierías, 2010
We describe a new species of the diverse genus Pristimantis. The new species is characterized by having a green dorsum with reddish marks, acuminate snout with papilla at tip, conical ulnar and tarsal tubercles, and by lacking cranial crests.

Height and phytotelm size affect the invertebrate communities of epiphytic bromeliads in the Amazon rainforest

Ecological Entomology, Volume 51, Issue 2, Page 221-234, April 2026.
The height at which epiphytic bromeliads are found affects the invertebrate community composition within them. The size of epiphytic bromeliads is positively correlated with species richness of both aquatic and terrestrial invertebrates. Whether bromeliads were found in primary or secondary forest did not have a significant effect on the community of ...

Phylogenomics reveals the evolution of floral traits associated with pollinators and pollinator–prey conflict within the carnivorous Pinguicula subgenus Temnoceras

American Journal of Botany, Volume 113, Issue 2, February 2026.
Abstract Premise The carnivorous plant genus Pinguicula (Lentibulariaceae) exhibits remarkable floral diversity associated with pollination, particularly in the largest subgenus Temnoceras, which spans Mexico and Central America. Despite this diversity, the relationships between species and the evolution of key floral traits remain unresolved. Here, we

Estructura poblacional de dos especies de Dichotomius Hope, 1838 (COLEOPTERA: SCARABAEINAE) en un paisaje cafetero de los andes occidentales de Colombia, Risaralda

Boletín Científico Centro de Museos Museo de Historia Natural, 2017
Los escarabajos coprófagos son un grupo de insectos ampliamente reconocido como indicador ecológico de perturbación antrópica, por lo cual cuentan con una gran cantidad de información a nivel de los ensamblajes. En contraste, aún son escasos los estudios a nivel poblacional y apenas se ha empezado a entender cómo la fragmentación y transformación de ...

Species functional traits affect regional and local dominance across western Amazonian forests

Journal of Ecology, Volume 114, Issue 1, January 2026.
Dominant tree species in western Amazonian forests show distinct functional trait combinations linked to habitat type: conservative traits in stressful habitats and greater plant size in less stressful environments. Local dominants are defined by resource conservation strategies and widespread dominants are defined by resource acquisition strategies. A

Plant functional traits shape the provision of ecosystem services to Indigenous communities in western Amazonia

People and Nature, Volume 7, Issue 12, Page 3313-3329, December 2025.
Abstract Context. Exploring how Indigenous People interact with plants through their functional traits allows us to understand the ecological bases of plant selection. Functional traits can help explain why certain plants are consistently chosen for specific purposes across diverse cultural contexts.

New species and new records in Agarista (Ericaceae) from the Peruvian Andes

Nordic Journal of Botany, Volume 2025, Issue 9, September 2025.
Agarista (Ericaceae) is currently represented in Peru by three species. Here, we update this number to five, adding new taxa based on the recognition of a taxonomic novelty and new records. The new species Agarista eugeniifolia differs from all congeneric species by an abaxially sulcate midvein.
