Toward more inclusive governance and conservation in the urbanizing Amazon

Conservation Science and Practice, Volume 8, Issue 7, July 2026.
We propose two paths toward a more inclusive approach to governance and conservation in the urbanizing Amazon: (1) grounding natural resource management programs in local‐level realities and (2) accounting for flows and transformations of place‐based relationships across the rural–urban interface.

Beyond mammals: the evolution of chewing and other forms of oropharyngeal food processing in vertebrates

Biological Reviews, Volume 101, Issue 3, Page 1406-1462, June 2026.
ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...

Parasitic Fauna of Free‐Living Chelonoidis denticulatus From the Rio Acre Ecological Station and the Municipality of Cruzeiro do Sul, Western Amazon, Brazil

Veterinary Medicine International, Volume 2026, Issue 1, 2026.
Tortoises, such as Chelonoidis denticulatus, are described as hosts of many parasites, such as helminths and ticks of the genus Amblyomma, which are important vectors of rickettsial infection in Brazil. Additionally, the high consumption of meat from these animals in Acre results in a high risk of zoonotic outbreaks due to contact with the hosts and ...

Simple radiography of the coelomic cavity in Podocnemis expansa and Podocnemis unifilis: proposal for an illustrative atlas as a diagnostic tool

Brazilian Journal of Animal and Environmental Research
Testudines are among the most popular reptiles chosen as exotic pets and, as a result, are referred more frequently for veterinary evaluation. However, it is difficult to investigate pathologies in these individuals due to their body conformation, which prevents a detailed physical examination.
