Genetic Issues in Freshwater Turtle and Tortoise Conservation TURTLE CONSERVATION GENETICS WORKING GROUP
– Freshwater and terrestrial turtles are among the most imperiled biota on the planet, with nearly half of all extant taxa threatened with extinction. Active science-based management is required for the persistence of many species. Evolutionary genetic principles are often overlooked in the development of conservation and management plans, yet genetic data and theory can be critical to program ...
متن کاملPleated turtle escapes the box--shape changes in Dermochelys coriacea.
Typical chelonians have a rigid carapace and plastron that form a box-like structure that constrains several aspects of their physiology and ecology. The leatherback sea turtle, Dermochelys coriacea, has a flexible bony carapace strengthened by seven longitudinal ridges, whereas the plastron is reduced to an elliptical outer bony structure, so that the ventrum has no bony support. Measurements ...
متن کاملCoastal habitat degradation and green sea turtle diets in Southeastern Brazil.
To show the influence of coastal habitat degradation on the availability of food for green turtles (Chelonia mydas), we assessed the dietary preferences and macroalgae community at a feeding area in a highly urbanized region. The area showed low species richness and was classified as degraded. We examined stomach contents of 15 dead stranded turtles (CCL=44.0cm (SD 6.7cm)). The diet was compose...
متن کاملSpecies boundaries and phylogenetic relationships in the critically endangered Asian box turtle genus Cuora.
Turtles are currently the most endangered major clade of vertebrates on earth, and Asian box turtles (Cuora) are in catastrophic decline. Effective management of this diverse turtle clade has been hampered by human-mediated, and perhaps natural hybridization, resulting in discordance between mitochondrial and nuclear markers and confusion regarding species boundaries and phylogenetic relationsh...
متن کاملThe Roundtable
Is it possible to abstract a formal mechanism originating schisms and governing the size evolution of social conversations? In this work we propose a constructive solution to this problem: an abstract model of a generic N-party turn-taking conversation. The model develops from simple yet realistic assumptions derived from experimental evidence, abstracts from conversation content and semantics ...
