Relationship between Plastron Color and Nutrition in Pseudemys nelsoni Carr, 1938 [PDF]

, 2022
Body coloration of emydids can be triggered by different types of factors. Therefore, the current study aimed to investigate the changes in plastron color of Florida Red-bellied Turtle Pseudemys nelsoni (P. nelsoni Carr, 1938), an emydid of North America.

Gas film transportation on asymmetric superhydrophobic mesh surfaces for excellent drag reduction and antiscaling properties

Friction
Manipulation of gas in an aqueous environment is fundamental to both academic research and industrial applications. In particular, the gas film on a superhydrophobic surface, referred to as a plastron, has fascinated scientists due to its potential ...

Morphology and genetic variation in the endangered tortoise Manouria emys: distinct lineages or plastron anomalies?

Mitochondrial DNA. Part B. Resources, 2018
Anecdotal reports indicate the allopatric populations of two Manouria emys subspecies differ in colour variation and plastron pattern, intimating that these may constitute separate evolutionary lineages.

Measuring air layer volumes retained by submerged floating-ferns Salvinia and biomimetic superhydrophobic surfaces

Beilstein Journal of Nanotechnology, 2014
Some plants and animals feature superhydrophobic surfaces capable of retaining a layer of air when submerged under water. Long-term air retaining surfaces (Salvinia-effect) are of high interest for biomimetic applications like drag reduction in ship ...

Environmental Contaminant Accumulation in Freshwater Turtles Inhabiting Three Rivers of the Permian Basin, New Mexico, USA

Environmental Toxicology, EarlyView.
ABSTRACT Freshwater turtles are valuable sentinels of aquatic systems due to their long lifespans and resilience in environments impacted by contaminants. The Permian Basin, dominated by the oil and gas sector, spans western Texas and southeastern New Mexico, USA, including the Pecos River and its tributaries, the Delaware and Black Rivers.

Importance of woody patches and vegetation heterogeneity in Texas tortoise microhabitat use

Wildlife Biology, EarlyView.
Microhabitat sites provide important resources and thermal conditions to reptile species that can vary spatially and temporally. This study assessed Texas tortoise Gopherus berlandieri microhabitat use and its relationship with carapace temperature during their active (April–October) and inactive seasons (November–March) between January 2023 and ...

Movement and Space Use Patterns of the Beale's Eyed Turtle (Sacalia bealei) Suggest Sensitivity to Environmental Changes and Poaching 比氏眼斑龟 (Sacalia bealei) 的活动与空间利用模式揭示其对环境变化及盗猎的敏感性

Wildlife Letters, EarlyView.
Using radiotelemetry, we found that the movement and home range of the endangered Sacalia bealei varied significantly across reproductive classes and seasons, with males exhibiting greater movement than females during wet and mating seasons. The species exhibits strong aquatic dependence, favoring deep pools interspaced among riffle‐pool sequences ...
