Pollen, Tapetum, and Orbicule Development in Colletia paradoxa and Discaria americana (Rhamnaceae)
The Scientific World Journal, 2012 Tapetum, orbicule, and pollen grain ontogeny in Colletia paradoxa and Discaria americana were studied with transmission electron microscopy (TEM). The ultrastructural changes observed during the different stages of development in the tapetal cells and ...

Environmental DNA succeeds in detecting a low‐density population of endangered harlequin frogs
Conservation Science and Practice, EarlyView.This work evaluates the use of environmental DNA (eDNA) to detect the Critically Endangered Jambato Harlequin Frog (Atelopus ignescens)—an iconic species once thought extinct and now known only from a single locality in the Ecuadorian Andes. Our study demonstrates the effectiveness of eDNA in detecting the Jambato in a low‐density amphibian population,

Ibis, EarlyView.Climatic change and anthropogenic disturbances are reshaping animal populations. Habitat loss and extreme climatic events are particularly strong drivers of declines in species that depend on forested areas. For migratory songbirds, climate and the persistence of suitable habitat over time are fundamental to sustaining populations annually.

Functional Ecology, Volume 40, Issue 5, Page 1270-1285, May 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Plants are shifting their flowering phenology in response to climate change, but trends differ between species and communities. Functional traits can largely explain how different species respond to climate change by shifting their phenology, and can therefore help ...

Pollination ecology of Syagrus smithii (Arecaceae), a palm with cantharophily from Colombian Amazon
Revista Peruana de Biología, 2017 From the evaluation floral morphology, reproductive phenology, floral biology, floral visitors and pollinator’s definition, the reproduction strategy of a Syagrus smithii (Arecaeae) in a Colombian Amazonia region was described. Syagrus smithii palms grow

American Journal of Botany, Volume 113, Issue 2, February 2026.Abstract Premise Flowers that present their anthers and stigma in close proximity can achieve precise animal‐mediated pollen transfer, but risk self‐pollination. One evolutionary solution is reciprocal herkogamy. Reciprocity of anther and style positions among different plants (i.e., a genetic dimorphism) is common in distylous plants, but very rare in

Functional Ecology, Volume 40, Issue 2, Page 323-337, February 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Sexual conflict affects the amount and duration of offspring care each parent invests, resulting in multiple parental care strategies sometimes coexisting within a single population.

New Phytologist, Volume 249, Issue 4, Page 2140-2152, February 2026.Summary Ecological network approaches have advanced our understanding of how species interactions influence community and evolutionary dynamics. However, a key limitation is that most network analyses rely solely on visitation data, often overlooking functional aspects of interactions.
