The matamatas (Chelus fimbriata and the recently described Chelus orinocensis) are the largest species in the family Chelidae, easily identified by their distinct morphological characteristics. The matamatas have a wide distribution in South America, occurring in Bolivia, Brazil, Colombia, Ecuador, Guyana, French Guiana, Peru, and Venezuela, as well as Trinidad and Tobago. However, there are many gaps in the knowledge of its distribution. The objective of this study was to present new records of occurrence for the C. fimbriata species complex and describe the area of distribution. We compiled data from published papers, databases in museums and other scientific collections, and research institutes and conservation organizations. From these data we mapped the species distribution, considering 3 types of river drainages based on water color in the Amazon Basin. We added 182 new records in Brazil, Venezuela, Colombia, Bolivia, and Peru, demonstrating that the C. fimbriata species complex has a wide distribution, totaling 6,907,551 km2 across all 3 river types. Most records were concentrated in areas lower than 200 m above sea level.","PeriodicalId":126915,"journal":{"name":"Chelonian Conservation and Biology: Celebrating 25 Years as the World's Turtle and Tortoise Journal","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130962997","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With 6 subspecies described, the rough-footed mud turtle (Kinosternon hirtipes) has been considered a species with high morphological diversity. One subspecies, K. h. megacephalum, is already extinct. The remaining subspecies are poorly studied, with very limited information available only for K. h. murrayi (a widespread subspecies). The remaining taxa (K. h. tarascense, K. h. chapalense, K. h. magdalense, and K. h. hirtipes) are microendemic and restricted to endorheic valleys in the Mexican Transvolcanic Belt. Using baited fyke nets, hoop traps, and a seine, we surveyed for these microendemic subspecies for 3 yrs across their known distributions. With the data gathered in the field and published information, we conducted a population viability analysis (PVA) to model the minimum characteristics needed to improve population growth under 3 scenarios (optimistic, intermediate, and pessimistic). Very few K. hirtipes turtles were collected. No K. h. chapalense were located in Lake Chapala, but we did capture 4 individuals in Lake Zapotlan. Similarly, only 6 individuals of K. h. magdalense were captured. No K. h. hirtipes individuals were collected in the Valley of México. Two populations of K. h. tarascense were located in the Pátzcuaro basin: the first populations reported for that subspecies. The PVA showed that harvest on adults in populations with fewer than 200 turtles significantly compromises population persistence. However, a population size of 200 and limited or no harvest are enough to increase population size and persistence for at least 100 yrs. Assurance colonies and head-starting may be the only chance for long-term survival of some of these microendemic turtle lineages.","PeriodicalId":126915,"journal":{"name":"Chelonian Conservation and Biology: Celebrating 25 Years as the World's Turtle and Tortoise Journal","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132116124","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Sierra Box Turtle, Terrapene nelsoni, comprises 2 recognized subspecies that are distributed across the Sierra Madre Occidental mountain chain in western Mexico and little is known about their natural history. We present new information on the natural history of Terrapene nelsoni klauberi. Our study area was the Monte Mojino reserve located within the larger Sierra de Alamos–Río Cuchujaqui federal protected area in southeastern Sonora. We located 49 individuals in 3 different vegetation types: 4 were found at 600 m above sea level (masl) in the tropical dry forest, 4 at 1000 masl in grassy oak (Quercus spp.) savannah, and 41 at 1300 masl in pine(Pinus spp.)–oak forest. Seven turtles were monitored using radiotelemetry and have the average home range size of 1.7 ha. The areas we sampled appear to consist of mainly adults and the sex ratio is female-biased (1♂:1.5♀). Cloacal temperatures of active turtles and their immediate surroundings suggest that T. n. klauberi actively maintain their body temperature above the surrounding temperatures. Males also have higher average body temperatures than females (29.58°C ± 2.26°C vs. 27.35°C ± 2.71°C). We found no significant patterns of sexual dimorphism in carapace length (i.e., sexual size dimorphism) but did find sexual dimorphism in head size. We also found that 44% of males and 22% of females had severe damage to their marginal scutes, possibly from a local predator or from enduring bites over time from other turtles. Lastly, we observed T. n. klauberi foraging on beetles, mushrooms, grass, and wildflowers. These findings provide a first insight into the natural history of T. n. klauberi and how this species is distributed across different elevations and vegetation types. This information provides a starting point to assess the conservation status of this species. However, this species remains unstudied throughout the rest of its geographic range.","PeriodicalId":126915,"journal":{"name":"Chelonian Conservation and Biology: Celebrating 25 Years as the World's Turtle and Tortoise Journal","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128754954","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Vallarta Mud Turtle (Kinosternon vogti) was recently described based solely on morphological characters; therefore, an examination of molecular data to determine the validity of this species is warranted. Here, mtDNA barcodes, phylogenetic trees, and three Operational Taxonomic Unit (OTU) analyses offer new evidence to support K. vogti as a distinct lineage within the Kinosternon complex. We generated 1,237 base pairs of the mitochondrial cytochrome oxidase I and cytochrome b genes from two paratype specimens collected at the species' type locality in Puerto Vallarta, Jalisco, Mexico, and compared them with 20 other sequences from BLAST belonging to close relatives representing 16 species. From these sequence data, we estimated genetic p-distances, reconstructed phylogenetic relationships among taxa, and performed 3 different operational taxonomic unit analyses (CD-HIT-EST DNA, ABGD, and Bayesian Poisson Tree Processes). The mean genetic p-distances over all sequence pairs was 0.083 ± 0.00 substitutions per site, with the average number of base pair differences per site between K. vogti and all remaining sequences being 0.083 ± 0.009. The closest species to K. vogti were K. hirtipes (p-distances 0.057 ± 0.00) and K. scorpioides (p-distances 0.058 ± 0.00). Phylogenetic trees from maximum likelihood and Bayesian analyses of the concatenated data set showed the same topology with generally high node support. The 3 operational taxonomic unit analyses identified K. vogti as a distinct OTU and likely a distinct evolutionary lineage.","PeriodicalId":126915,"journal":{"name":"Chelonian Conservation and Biology: Celebrating 25 Years as the World's Turtle and Tortoise Journal","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126920697","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
