DNA metabarcoding reveals greater plant diversity than morphological seed analysis of bird feces

open access: yesApplications in Plant Sciences, EarlyView.
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 ...

Animal‐mediated seed dispersal: A review of study methods

open access: yesApplications in Plant Sciences, EarlyView.
Abstract By dispersing seeds, animals provide ecological functions critical for the ecology, evolution, and conservation of plants. We review quantitative and empirical approaches and emerging technologies to quantify processes and patterns of animal‐mediated seed dispersal (zoochory) across its phases: from predispersal to postdispersal.

Effect of Ramped Oxygen Flow During Magnetron Sputtering on the Structural, Optical, and Photoelectrochemical Properties of WO3‐x Thin Films

open access: yesAdvanced Physics Research, EarlyView.
A compositionally graded WO3‐x thin film was engineered through a controlled linear increase of oxygen flow during reactive magnetron sputtering. This deposition strategy yields a gradual transition from an oxygen‐deficient, conductive bottom layer to a more stoichiometric and crystalline surface layer, forming an intrinsic gradient homojunction.

Histovariability and fossil diagenesis of Pissarrachampsa (Pseudosuchia, Notosuchia, Baurusuchidae) from the Upper Cretaceous of Southeast Brazil

open access: yesThe Anatomical Record, EarlyView.
Abstract Notosuchians were key components of western Gondwanan Cretaceous ecosystems in terrestrial predator niches and exhibited remarkable taxonomic and ecological diversity. Previous research has explored their physiology, metabolism, and histology, revealing varied growth patterns and life history strategies.
