nest environments and egg physiology

making measurements of leatherback nest environment conditions

Sea turtle embryos are literally ‘buried alive’; they develop inside eggs while buried in 40-100 cm of sand. Characteristics of the nest environment (e.g. temperature, oxygen, number of eggs) influence development of embryos and hatching success of clutches, and thus reproductive success of female turtles.

My research has dealt with how biological and physical factors affect embryonic development, as well as how females invest in their eggs and thus in their offspring.

publications:

review of leatherback egg and nest traits

inferred sex ratios of leatherbacks over time

biotic and abiotic factors affect leatherback embryos

variation in leatherback nest environments

effects of egg location and respiratory gas concentrations

egg components, egg size, and hatchling size

maternal investment in reproduction by leatherbacks

environmental effects on leatherback hatching success
