Socioeconomic drivers of wild meat consumption in the city of Iquitos, Peru. [PDF]

Conserv Biol
Abstract Wild meat represents a vital source of micro‐ and macronutrients for forest‐dwelling people; however, city dwellers with access to animal protein from different animals may also consume large amounts of wild meat as part of their customs and traditions, to diversify their diets, to maintain connections to their rural kin, and to access meat ...

Refractometry as an alternative to the biuret method for measuring total serum proteins in Podocnemis expansa (Podocnemididae) and Phrynops geoffroanus (Chelidae) [PDF]

Acta Amazonica, 2017
Total serum protein is a significant indicator of health condition in animals. The aim of this study was to analyze the precision of the portable refractometer in determining the concentration of total serum proteins in Podocnemis expansa and Phrynops ...

Shell Constraints on Evolutionary Body Size-Limb Size Allometry Can Explain Morphological Conservatism in the Turtle Body Plan. [PDF]

Ecol Evol
Turtle body size and limb size scale nearly isometrically along the group's evolution, although major deviations are only seen in highly specialized ecological or morphological groups. The evolution of the shell constrained turtle body proportions, as they show lower rates of variance accumulation in these allometries than other more diverse and ...

Sincronia entre o regime de vazante do rio e o comportamento de nidificação da tartaruga da Amazônia Podocnemis expansa (Testudinata: Pelomedusidae) [PDF]

Acta Amazonica, 1982
Resumo Há uma sincronização entre a vazante e o desencadeamento do comportamento de nidificação da tartaruga da Amazônia Podocnemis expansa. O comportamento de nidificação só começa quando o nível da água se estabiliza em seu nível mais baixo.

Community-Based Conservation and Management of Chelonians in the Amazon

Frontiers in Ecology and Evolution, 2022
Chelonians represent an important resource in the Amazon, either as a source of protein at the base of the food chain of aquatic and transition ecosystems, or in the dispersion of seeds of plants from floodplains and flooded forests.

Detection of anti-Leptospira spp. agglutinins in captive South American river turtles, Podocnemis expansa [PDF]

Acta Amazonica, 2020
Leptospirosis is a zoonosis transmitted by contact with infected urine or water contaminated with the agent. Searches for Leptospira spp. in reptiles are scarce although most species have contact with aquatic environments.

Molecular detection of hemogregarines and haemosporidians in Brazilian free-living testudines

International Journal for Parasitology: Parasites and Wildlife, 2018
Morphological and molecular techniques were used to investigate the presence of hemogregarines and haemosporidians in biological samples of free-living Geoffroy's side-necked turtles (Phrynops geoffroanus) and Giant Amazon turtles (Podocnemis expansa ...

A systematic compendium of turtle mandibular anatomy using digital dissections of soft tissue and osteology

The Anatomical Record, Volume 306, Issue 6, Page 1228-1303, June 2023., 2023
Abstract Turtles are a charismatic reptile group with a peculiar body plan, which most notably includes the shell. Anatomists have often focused descriptive efforts on the shell and other strongly derived body parts, such as the akinetic skull, or the cervical vertebrae.
