Phenological strategies of an evergreen tree in the Caatinga

PLOS ONE
Seasonally Dry Tropical Forests (SDTF) account for 40% of global tropical forests, with the Caatinga standing out as the largest continuous formation of this type. However, the region faces severe threats, such as deforestation and desertification, which require urgent conservation efforts.

The Role of Gene Flow in the Diversification of the Monkey Treefrog Complex Across the South American Dry Diagonal

Zoologica Scripta, Volume 55, Issue 4, Page 568-588, July 2026.
ABSTRACT Understanding Neotropical megadiversity remains challenging due to fundamental taxonomic issues, including identifying and describing cryptic species and their distribution, and the limited knowledge of key factors driving biological diversification. Such challenges are especially prominent in diverse clades with high levels of cryptic species,

Interplay Between River Formation and Historical Climatic Changes Drove Diversification of the Thamnomanes caesius and T. schistogynus (Passeriformes, Thamnophilidae) Species Complex Across Amazonian and Atlantic Forests

Zoologica Scripta, Volume 55, Issue 4, Page 555-567, July 2026.
ABSTRACT The Amazon and Atlantic forests harbour immense biodiversity shaped by complex evolutionary history with diverse processes leading to species build‐up. We investigated the Cinereous Antshrike species complex (Thamnomanes caesius and T. schistogynus) to disentangle the relative contributions of riverine barriers and historical climatic ...

Impacts of Deforestation‐Driven Rainfall Reductions on Amazonia Forest Stability

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract The stability of Amazonian vegetation is strongly influenced by land–atmosphere feedbacks. It has been hypothesized that deforestation‐induced precipitation decline may lead to widespread forest decline across the entire basin. Using a moisture‐tracking model, we quantify how deforestation across South America alters downwind rainfall and ...

Can I Have a Bite? The Influence of Infant Begging on Food Sharing in Capuchin Monkeys (Sapajus Libidinosus)

American Journal of Primatology, Volume 88, Issue 6, June 2026.
Food sharing between mother and offspring in capuchin monkeys is a response to the infant's begging. Infants solicit more frequently high‐quality and hard‐to‐process foods and they are more likely to succeed when they are older and if the food item is not a lizard. ABSTRACT In primates, food sharing from mothers to infants may serve two main functions:
