Vulnerability of marine megafauna to global at‐sea anthropogenic threats

open access: yesConservation Biology, Volume 40, Issue 1, February 2026.
Abstract Marine megafauna species are affected by a wide range of anthropogenic threats. To evaluate the risk of such threats, species’ vulnerability to each threat must first be determined. We build on the existing threats classification scheme and ranking system of the International Union for Conservation of Nature (IUCN) Red List of Threatened ...

Are thermal barriers "higher" in deep sea turtle nests?

open access: yesPLoS ONE, 2017
Thermal tolerances are affected by the range of temperatures that species encounter in their habitat. Daniel Janzen hypothesized in his "Why mountain passes are higher in the tropics" that temperature gradients were effective barriers to animal movements

Ontogeny and ecological significance of metabolic rates in sea turtle hatchlings

open access: yesFrontiers in Zoology, 2022
Background Sea turtle hatchlings must avoid numerous predators during dispersal from their nesting beaches to foraging grounds. Hatchlings minimise time spent in predator-dense neritic waters by swimming almost continuously for approximately the first 24

Global analysis of the effect of local climate on the hatchling output of leatherback turtles [PDF]

open access: yes, 2016
Santidrián Tomillo, Pilar et al.The most recent climate change projections show a global increase in temperatures along with precipitation changes throughout the 21 century. However, regional projections do not always match global projections and species

Informing research priorities for immature sea turtles through expert elicitation

open access: yesEndangered Species Research, 2018
Although sea turtles have received substantial focus worldwide, research on the immature life stages is still relatively limited. The latter is of particular importance, given that a large proportion of sea turtle populations comprises immature ...

Crying a river: how much salt-laden jelly can a leatherback turtle really eat? [PDF]

open access: yes, 2017
Leatherback turtles (Dermochelys coriacea) are capital breeders that accumulate blubber (33 kJ g−1 wet mass) by hyperphagia on a gelatinous diet at high latitudes; they breed in the tropics.
