  • Liles et al. 2018_Egg relocation and thermal sensitivities

    Scientific Research - November 14, 2019
    Potential limitations of behavioral plasticity and the role of egg relocation in climate change mitigation for a thermally sensitive endangered species Anthropogenic climate change is widely considered a major threat to global biodiversity, such that the ability of a species to adapt will determine its likelihood of survival. Egg‐burying reptiles that ...

  • Gaos et al. 2018_Prevalence of polygyny in hawksbills at Bahia de Jiquilisco, El Salvador (Íngles)

    Scientific Research - November 14, 2019
    Prevalence of polygyny in a critically endangered marine turtle population Genetic analyses of nuclear DNA (e.g., microsatellites) are a primary tool for investigating mating systems in reptiles, particularly marine turtles. Whereas studies over the past two decades have demonstrated that polyandry (i.e., females mating with multiple males) is common in marine ...

    Scientific Research - November 14, 2019
    Rookery contributions, movements and conservation needs of hawksbill turtles at foraging grounds in the eastern Pacific Ocean Understanding the spatial ecology of wide-ranging marine species is fundamental to advancing ecological research and species management. For marine turtles, genetic studies using mitochondrial DNA (mtDNA) markers have proven invaluable to characterize movement, particularly ...

    Scientific Research - October 16, 2017
    Natal foraging philopatry in eastern Pacific hawksbill turtles The complex processes involved with animal migration have long been a subject of biological interest, and broad-scale movement patterns of many marine turtle populations still remain unresolved. While it is widely accepted that once marine turtles reach sexual maturity they home to natal ...

    Scientific Research - August 5, 2017
    Distribution, size range and growth rates of hawksbill turtles at a major foraging ground in the eastern Pacific Ocean Hawksbill sea turtles (Eretmochelys imbricata) inhabiting the eastern Pacific Ocean are one of the world’s most threatened marine turtle management units. Despite the fact that knowledge about the status of sea turtles at ...

    Scientific Research - August 5, 2017
    Living on the Edge: Hawksbill turtle nesting and conservation along the Eastern Pacific Rim Prior to 2007, efforts to monitor and conserve hawksbill turtles (Eretmochelys imbricata) in the eastern Pacific Ocean were opportunistic and records were virtually non-existent. The first abundance estimates were published in 2010, but contained limited data on the ...

  • Zuñiga-Marroquin et al. 2017_Hawksbill genetics along Pacific Mexico

    Scientific Research - August 5, 2017
    Genetic characterization of the Critically Endangered hawksbill turtle (Eretmochelys imbricata) from the Mexican Pacific region The hawksbill turtle (Eretmochelys imbricata) is a Critically Endangered species and has been a species of interest for decades. Only in recent years attention has been focused on the populations of the Eastern Pacific Ocean. We ...

    Scientific Research - August 5, 2017
    Survival on the rocks: high bycatch in lobster gillnet fisheries threatens hawksbill turtles on rocky reefs along the Eastern Pacific coast of Central America Small-scale coastal fisheries can cause detrimental impacts to non-target megafauna through bycatch. This can be particularly true when high-use areas for such species overlap with fishing grounds, as ...

    Scientific Research - February 21, 2016
    First record of hybridization between green Chelonia mydas and hawksbill Eretmochelys imbricata sea turtles in the Southeast Pacific Hybridization among sea turtle species has been widely reported in the Atlantic Ocean, but their detection in the Pacific Ocean is limited to just two individual hybrid turtles, in the northern hemisphere. Herein, we report, ...

  • Gaos et al. 2016_Conservation genetics of eastern Pacific hawksbills

    Scientific Research - February 5, 2016
    Hawksbill turtle terra incognita: conservation genetics of eastern Pacific rookeries Prior to 2008 and the discovery of several important hawksbill turtle (Eretmochelys imbricata) nesting colonies in the EP (Eastern Pacific), the species was considered virtually absent from the region. Research since that time has yielded new insights into EP hawksbills, salient among ...
