Gonadal development in scorpion mud‐turtles, Kinosternon scorpioides, in a controlled environment
The Anatomical Record, EarlyView.Stage 20 was identified as the critical point for gonadal differentiation in Kinosternon scorpioides, providing key insights into sex determination. These findings enhance conservation strategies by supporting reproductive management and population viability in both in situ and ex situ programs. Abstract Research on gonadal development including sexual

Tracing the origins and evolution of nymphalid butterflies (Lepidoptera) in the Atlantic Forest
Ecography, EarlyView.Understanding the relative roles of diversification and dispersal is key to explaining large‐scale biogeographical patterns. Although both processes are known to shape biodiversity, their relative contributions remain understudied for many organisms. Here, we examine how these processes have jointly contributed to the exceptional diversity and endemism

Heat and Cold Waves in Brazil: An ERA5‐Based Analysis of Trends and Seasonality (1980–2024)
International Journal of Climatology, EarlyView.This study uses ERA5 reanalysis data to assess changes in extreme heat and cold events across Brazil from 1980 to 2024. Results reveal a sharp increase in heatwave frequency and a general decline in coldwave occurrences, though regional variations are substantial.

Liana regeneration in secondary and primary forests of central Amazonia
Plant Ecology & Diversity, 2010 Background: Lianas are considered to be particularly abundant in tropical forests after disturbance; however, information on their regeneration by seedlings, saplings, and sprouts is scarce. Aim: We assessed how primary and secondary forest types with different land use history are related to the density and diversity of liana regeneration.
