Corrigendum to “Migratory corridors of adult female Kemp's ridley turtles in the Gulf of Mexico” [Biol. Conserv. 194 (2016) 158–167]

One Shell of a Problem: Cumulative Threat Analysis of Male Sea Turtles Indicates High Anthropogenic Threat for Migratory Individuals and Gulf of Mexico Residents

“…Species that conduct long migrations are particularly at risk, such as elasmobranchs [29,30], pinnipeds [31,32], cetaceans [33,34], and chelonids [27,[35][36][37]. To best protect migratory marine species, researchers rely on tracking individuals to better understand the threats they encounter within and en-route to their feeding and breeding locations [7,[29][30][31]35,36,[38][39][40][41][42][43][44]. Locations where species of interest aggregate can be used by managers to design strategies that protect them, for example by establishing or expanding marine protected areas (MPAs) [7,39,42].…”

“…Australian flatback turtles (Natator depressus) are Data Deficient [68]. During nesting years, adult female sea turtles will undergo migrations of up to thousands of kilometers to their natal beaches to nest, often traveling through areas with high human activity [7,44,[69][70][71]. Female turtles aggregate in the vicinity of nesting sites for the duration of the mating season, where they lay multiple clutches of eggs before returning to their foraging grounds [72,73].…”

“…However, due to differences in habitat, species may vary in the degree to which they encounter various threats [40]. Kemp's ridleys, for example, nest almost exclusively in Rancho Nuevo, Mexico, and are primarily found in the Gulf of Mexico, exposing them to a larger number of threats derived from oil pollution than hawksbill sea turtles, who are more confined to coral reefs and other tropical climates, at least within Caribbean, Southern Gulf of Mexico, and Atlantic populations [20,44,[80][81][82]. Another study found that female Kemp's ridleys have much larger foraging ranges than loggerhead turtles, and minimal overlap of foraging grounds within the Gulf of Mexico, exhibiting spatial partitioning of habitat, which could indicate different exposure to certain human threats [40].…”

“…The tracking of male sea turtles is important from a conservation standpoint, as they exhibit different movement patterns than females [42,44]. While some male sea turtles reside near nesting beaches year-round, others have been found to exhibit longdistance migrations between breeding and feeding grounds with unique timing compared to females [42,44,90].…”

“…The tracking of male sea turtles is important from a conservation standpoint, as they exhibit different movement patterns than females [42,44]. While some male sea turtles reside near nesting beaches year-round, others have been found to exhibit longdistance migrations between breeding and feeding grounds with unique timing compared to females [42,44,90]. Migrations often remove species from protected areas into locations that increase an individual's risk of mortality from human interaction, such as artisanal and benthic fishing fleets in international waters or boundaries of countries where protection is weak [35,91].…”
