Conservation implications of historic sea turtle nesting beach loss
Populations of endangered Caribbean sea turtles are far more depleted than realized because current conservation assessments do not reflect historic nesting data. We used historical sources to analyze changes in the numbers of nesting populations and population sizes for green and hawksbill turtles on all known nesting beaches in the Caribbean over the past millennium. We present the first maps...
متن کاملEarlier nesting by loggerhead sea turtles following sea surface warming
The onset of spring, noted by the timing of wildlife migratory and breeding behaviors, has been occurring earlier over the past few decades. Here, we examine 15 years of loggerhead sea turtle, Caretta caretta, nesting patterns along a 40.5 km beach on Florida’s Atlantic coast. This small section of beach is considered to be the most important nesting area for this threatened species in the west...
متن کاملSea turtle nesting distributions and oceanographic constraints on hatchling migration.
Patterns of abundance across a species's reproductive range are influenced by ecological and environmental factors that affect the survival of offspring. For marine animals whose offspring must migrate long distances, natural selection may favour reproduction in areas near ocean currents that facilitate migratory movements. Similarly, selection may act against the use of potential reproductive ...
متن کاملLong-Term Climate Forcing in Loggerhead Sea Turtle Nesting
The long-term variability of marine turtle populations remains poorly understood, limiting science and management. Here we use basin-scale climate indices and regional surface temperatures to estimate loggerhead sea turtle (Caretta caretta) nesting at a variety of spatial and temporal scales. Borrowing from fisheries research, our models investigate how oceanographic processes influence juvenil...
متن کاملEvaluation of hematological and plasma biochemical parameters in green sea turtle (Chelonia mydas Linnaeus, 1758) from nesting colonies of the northern coast the Sea of Oman
The green turtle (Chelonia mydas) has been a species of global concern for decades. As an attempt to study health status of nesting green turtles, Blood biochemistry and hematological values were obtained from 18 clinically normal, nesting female green sea turtles on the northern coast of the sea of Oman. Mean curved carapace length (CCL) was 111±4 cm with a range of 103—122 cm. Barnacles were ...
