Missing Data in Sea Turtle Population Monitoring: A Bayesian Statistical Framework Accounting for Incomplete Sampling

Frontiers in Marine Science, 2022
Monitoring how populations respond to sustained conservation measures is essential to detect changes in their population status and determine the effectiveness of any interventions.

Leatherback turtles: The menace of plastic [PDF]

Marine Pollution Bulletin, 2009
The leatherback, Dermochelyscoriacea, is a large sea turtle that feeds primarily on jellyfish. Floating plastic garbage could be mistaken for such prey. Autopsy records of 408 leatherback turtles, spanning 123 years (1885-2007), were studied for the presence or absence of plastic in the GI tract. Plastic was reported in 34% of these cases.

Increased captures of the critically endangered leatherback turtle (Dermochelys coriacea) around New Zealand: the contribution of warming seas and fisher behavior

Frontiers in Marine Science, 2023
Five species of sea turtles are known to occur in New Zealand waters, with the leatherback turtle (Dermochelys coriacea) being the most frequently reported.

Community Engagement: An Integral Component of a Multifaceted Conservation Approach for the Transboundary Western Pacific Leatherback

Frontiers in Marine Science, 2020
Bycatch in fisheries is one of the greatest threats to marine megafauna such as sea turtles, and the Biodiversity Impact Mitigation Hierarchy (BIMH) has been proposed as an improved and holistic approach for integrating fisheries management with sea ...

Interaction Between Age and Individual Heterogeneity Shapes Breeding Probability in a Long-Lived Marine Ectotherm. [PDF]

Ecol Evol
Using a 52‐year dataset on captive green turtles, our study reveals that individual quality and age are the primary drivers of reproductive patterns. We found that high‐quality turtles bred more consistently throughout their lives and that females maintained a high reproductive value into old age despite evidence of physical aging.

Interannual Differences for Sea Turtles Bycatch in Spanish Longliners from Western Mediterranean Sea

The Scientific World Journal, 2014
Recent studies showed that regional abundance of loggerhead and leatherback turtles could oscillate interannually according to oceanographic and climatic conditions. The Western Mediterranean is an important fishing area for the Spanish drifting longline

Are coastal protected areas always effective in achieving population recovery for nesting sea turtles? [PDF]

PLoS ONE, 2013
Sea turtles are highly migratory and usually dispersed, but aggregate off beaches during the nesting season, rendering them vulnerable to coastal threats.

Hierarchical state-space estimation of leatherback turtle navigation ability. [PDF]

PLoS One, 2010
Remotely sensed tracking technology has revealed remarkable migration patterns that were previously unknown; however, models to optimally use such data have developed more slowly. Here, we present a hierarchical Bayes state-space framework that allows us to combine tracking data from a collection of animals and make inferences at both individual and ...

Spatial ecology and conservation of leatherback turtles (Dermochelys coriacea) nesting in Bioko, Equatorial Guinea.

PLoS ONE, 2023
Bioko Island (Equatorial Guinea) hosts important nesting habitat for leatherback sea turtles, with the main nesting beaches found on the island's southern end.

Influence of incubation temperature on morphology and locomotion performance of Leatherback (Dermochelys coriacea) hatchlings [PDF]

, 2010
The journey of Leatherback (Dermochelys coriacea (Vandelli, 1761)) hatchlings from nest to the sea is a vulnerable life-history stage. Studies have shown that nest incubation temperatures influence hatchling morphology and locomotor performance, which ...
