The conservation status of the world's reptiles
TLDR
The results provide the first analysis of the global conservation status and distribution patterns of reptiles and the threats affecting them, highlighting conservation priorities and knowledge gaps which need to be addressed urgently to ensure the continued survival of the world’s reptiles. Expand
HERITABILITY OF SEX RATIO IN TURTLES WITH ENVIRONMENTAL SEX DETERMINATION
TLDR
The question of adaptive sex ratio is addressed in much of the recent evolutionary literature and there is a growing concern that many species may lack the type of genetic variation for sex ratio on which these evolutionary models depend. Expand
SEX DETERMINING TEMPERATURES IN TURTLES: A GEOGRAPHIC COMPARISON
TLDR
Here, however, it is considered how the sex ratio evolves in response to the environment, rather than evolution of the sex de- evolution. Expand

TLDR
This study investigates the developmental period of temperature-sensitivity in two species of emydid turtles, using different combinations of incubation at a male-determining temperature (25 degrees C) and at a female-d determining temperature (31 degrees C). Expand
Temperature-dependent sex determination in turtles.
The sex of hatchling map turtles is determined by incubation temperature of eggs in the laboratory as well as in nature. Temperature controls sex differentiation rather than causing a differentialExpand
Global Conservation Status of Turtles and Tortoises (Order Testudines)
TLDR
The order Testudines is, on average, more imperiled than all other larger orders (≥ 20 species) of Reptilia, Amphibia, Mammalia, or Aves, but has percentages of CR+EN and Threatened species and an ATL similar to those of Primates and Caudata (salamanders). Expand
FOOD HABITS OF AN ASSEMBLAGE OF FIVE SPECIES OF TURTLES IN THE RIO GUAPORE, RONDONIA, BRAZIL
TLDR
The feeding habits of five species of turtles were studied from June-November 1989 and March-June 1990 in the Guapore River and its tributaries in Costa Marques, Rondonia, Brazil and found no seasonal differences in food consumed by P. unifilis; however, differences were found between the sexes.

Food Partitioning in Three Sympatric Species of Map Turtle, Genus Graptemys (Testudinata, Emydidae)
TLDR
Three species of map turtle, Graptemys geographica, G. ouachitensis and G. pseudo geo graphic a, inhabit the Mississippi River near Stoddard, Vernon Co., Wiscon- sin and in Arkansas, G pseudo geo graphica is a mollusk specialist. Expand
