Open Rivers Rethinking Water Place & Community, 2022 “Amazonia”—the word alone can conjure up a lot of images, some accurate and some wildly not. In truth, it has many definitions, ranging from a specific drainage basin to a tropical ecological world. For most of my childhood, such kinds of tropical “jungles” were places of peril to be avoided.

Rarity of monodominance in hyperdiverse Amazonian forests. [PDF]
, 2019 Tropical forests are known for their high diversity. Yet, forest patches do occur in the tropics where a single tree species is dominant. Such "monodominant" forests are known from all of the main tropical regions. For Amazonia, we sampled the occurrence

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
