1. The influence of season, environment, sex, and body mass on biochemical profile of the freshwater turtle Phrynops geoffroanus (Schweigger, 1812)
RESUMO Analisou-se a influência da estação, do ambiente e do sexo, assim como a relação da massa corporal (BM) nos níveis sorológicos de albumina (ALB), aspartato aminotransferase (AST), creatinina (C), creatina quinase (CK), fósforo (P), cálcio total (tCa), sólidos totais (TS), ureia (U), ácido úrico (UA), relação cálcio:fósforo (Ca:P), e do

2. Mercury and methylmercury in carapace of the marine turtle Caretta caretta, in northeastern Brazil and its potential for environmental monitoring
Abstract: The present work tests the use of carapace fragments of the marine turtle Caretta caretta as a tool for environmental biomonitoring of mercury (Hg) and to evaluate the influence of biological and ecological factors in Hg concentrations. Samples of carapace fragments were obtained during the nesting season of 2012 and 2016 and were analyzed for thei

3. The trophic niche of Mesoclemmys vanderhaegei (Testudines: Chelidae): evidence from stable isotopes
ABSTRACT Ecological niche is the multidimensional space comprising the resources used by an organism. Intraspecific variation in resource exploitation is common in reptile populations to maximize coexistence of individuals. The use of stable isotope analysis is an effective tool when there are variations in resource exploitation, since it can provide quantit

4. Influence of artificial lights on the orientation of hatchlings of Eretmochelys imbricata in Pernambuco, Brazil
ABSTRACT Sea turtle hatchlings, in natural abiotic conditions, emerge from their nests at night and go directly to the sea, following the moonlight’s reflection in the ocean. Increased human activities such as tourism and artificial lights on the coasts, however, have interfered with the ability of sea turtle neonates to find their correct destination, neg

5. Green turtle (Chelonia mydas) genetic diversity at Paranaguá Estuarine Complex feeding grounds in Brazil
Sea turtles are marine reptiles that undertake long migrations through their life, with limited information regarding juvenile stages. Feeding grounds (FGs), where they spend most of their lives, are composed by individuals from different natal origins, known as mixed stock populations. The aim of this study was to assess genetic composition, natal origins a

6. The lowest diploid number in Testudines: Banding patterns, telomeric and 45S rDNA FISH in Peltocephalus dumerilianus, 2n = 26 and FN = 52 (Pleurodira, Podocnemididae)
The karyotype of the big-headed Amazon River turtle, Peltocephalus dumerilianus, is characterized based on a sample of seven juveniles from Reserva Biológica do Rio Trombetas, Pará State, Brazil (1°30' S, 56°34' W). Here we present the first results on GTG and CBG-banding patterns, Ag-NOR staining and FISH, with telomeric and 45S rDNA sequences as probes

7. New record of Clypeasterophilus stebbingi (Rathbun, 1918) (Decapoda: Brachyura: Pinnotheridae) from the east coast of Nicaragua
The pinnotherid crab Clypeasterophilus stebbingi (Rathbun, 1918), previously known from Florida, USA, Colombia and Brazil, is reported for the first time from Central America, on the east coast of Nicaragua. A single female specimen was collected on the sand dollar Clypeaster subdepressus (Gray, 1825), at 4 m depth, among turtle grass on sandy bottom. The sp

8. Socio-economic and spatial determinants of anthropogenic predation on Yellow-spotted River Turtle, Podocnemis unifilis (Testudines: Pelomedusidae), nests in the Brazilian Amazon: Implications for sustainable conservation and management
Human expansion has drastically affected wildlife species across Amazonian waterways and the continued increase in rural populations across Amazonia is likely to increase pressure on widely exploited chelonian species. The lack of information evaluating determinants of human consumption patterns limits the effective implementation of conservation strategies.

9. Turtle ectoparasites from the Pacific coastal region of Colombia
This study provides an update on the ectoparasites (ticks and leeches) associated with Rhinoclemmys annulata and provides new accounts on the ectoparasites associated with R. nasuta, R. melanosterna andKinosternon leucostomum from the Pacific coast of Colombia. The presence ofAmblyomma sabanerae on R. nasuta and R. melanosterna provided two new host records

12. New turtle egg fossil from the Upper Cretaceous of the Laiyang Basin, Shandong Province, China
Uma nova espécie de ovo de tartaruga fóssil foi estabelecida: Emydoolithus laiyangensis oogen. et oosp. nov. Esta possui forma elíptica, uma casca rígida e outras características da casca que diferem dos demais ovos fósseis de quelônios conhecidos, todos de forma arredondada. Trata-se da segunda espécie de ovo fóssil de quelônio encontrado no Cret�
