DNA metabarcoding reveals greater plant diversity than morphological seed analysis of bird feces
Applications in Plant Sciences, Volume 14, Issue 1, January-February 2026.Abstract Premise Fruit‐eating birds drive seed dispersal in recovering tropical ecosystems, shaping forest regeneration. Molecular techniques, such as DNA metabarcoding, enable diet analysis from feces and can provide complementary frugivory data where dispersal is infrequent, as well as aid in seed identification in hyper‐diverse regions lacking ...

Taxonomy, natural history, and conservation ofParoaria baeri(Aves: Thraupidae) [PDF]
Tropical Zoology, 2013 Paroaria baeri (Crimson-fronted Cardinal) is a poorly known and uncommon species, inhabiting low vegetation growing along the edges of water bodies in central Brazil. Having collected new specimens along the Rio Araguaia, we revised the taxonomy of this species by examining plumage coloration and morphometric data of 36 specimens housed in Brazilian ...

Journal of Biogeography, Volume 53, Issue 1, January 2026.ABSTRACT Aim The study of the structure of species assemblages has typically assumed that similar environments share common species; however, interacting biogeographic and phylogenetic processes are equally important. The understanding that ecological processes operate at different spatial scales to shape species assemblages led to the concept of ...
