A dynamic energy budget model to describe the reproduction and growth of invasive starfish Asterias amurensis in southeast Australia

The DEB model allowed us to characterise the ecophysiology of A. amurensis, providing new insights on the role of food availability and temperature on its life cycle and reproduction strategy, and is a powerful tool for risk management of already established invasive populations and of regions with a high invasion risk.

A dynamic energy budget model to describe the reproduction and growth of invasive starfish Asterias amurensis in southeast Australia

The introduction of alien species is a global phenomenon that alters ecosystems structure and functioning. Invasive species are responsible for substantial economic and ecological losses. Invasive

A Review of the Effects of Climate Change on Chelonians

Climate change is occurring at an unprecedented rate and has begun to modify the distribution and phenology of organisms worldwide. Chelonians are expected to be particularly vulnerable due to

Unusually Paced Life History Strategies of Marine Megafauna Drive Atypical Sensitivities to Environmental Variability

Understanding why different life history strategies respond differently to changes in environmental variability is necessary to be able to predict eco-evolutionary population responses to change.

Physiological performance of native and invasive crayfish species in a changing environment: insights from Dynamic Energy Budget models

Abstract Crayfish are keystone species important for maintaining healthy freshwater ecosystems. Crayfish species native to Europe, such as Astacus astacus and Austropotamobius torrentium, are facing

A Systematic Review of Metabolic Heat in Sea Turtle Nests and Methods to Model Its Impact on Hatching Success

Overall it is found metabolic heat increases throughout incubation in all seven species, and developing a generalisable mechanistic model that incorporates metabolic heat will be critical for predicting incubation success as the sand temperatures at sea turtle beaches increase due to anthropogenic climate change.



Inferring physiological energetics of loggerhead turtle (Caretta caretta) from existing data using a general metabolic theory

A full life cycle model based on the principles of energy acquisition and utilization embedded in the Dynamic Energy Budget (DEB) theory is constructed and physiological traits such as the capacity to withstand starvation, trade-offs between reproduction and growth, and changes in the energy budget throughout the ontogeny were inferred from the model.


Somatic growth functions of oceanic-stage loggerheads from the eastern Atlantic are evaluated for the first time in wild sea turtles and the time-dependent nature of somatic growth is evaluated by distinguishing among age, year, and cohort effects using a mixed longitudinal sampling design with assigned-age individuals.

Predicting the impacts of climate change on a globally distributed species: the case of the loggerhead turtle

The likely impacts of climate change on the biology of these species, which are likely centred upon the thermal ecology of this taxonomic group, are overview and how much progress has been made and how future experimental and ecological focus should be directed are described.

Climate change and marine turtles

Marine turtles occupy a wide range of terrestrial and marine habitats, and many aspects of their life history have been demonstrated to be closely tied to climatic variables such as ambient

Estimation of age at maturity of loggerhead sea turtles Caretta caretta in the Mediterranean using length-frequency data

The results indicate that turtles would take from 23.5 to 29.3 yr to reach 80 cm CCL, considered an approximation of the size at maturity, which integrates and confirms a previous estimate obtained using a different method.

Silver spoons and snake body sizes: prey availability early in life influences long-term growth rates of free-ranging pythons

These pythons displayed a strong ‘silver spoon’ effect, whereby favourable conditions in the first year of life exerted a long-term effect on growth trajectories and thus, adult body sizes, which were strongest in the faster-growing sex (females).

Somatic growth model of juvenile loggerhead sea turtles Caretta caretta: duration of pelagic stage

A growth model and estimates for duration of the pelagic juvenile stage for loggerhead sea turtles Caretta caretta in the North Atlantic based on length-frequency analyses and sizes of young-of-the-year stranded in the Azores are presented.


—The International Union for Conservation of Nature (IUCN) lists the Loggerhead Sea Turtle (Caretta caretta) as an endangered species. Therefore, its protection and recovery requires effective

Growth rates of juvenile loggerheads, Caretta caretta, in the southern Bahamas

Growth rates of these smaller loggerheads are more rapid than those reported for larger turtles and result in significantly shorter estimates for the time necessary for loggerheads to grow from 25 to 75 cm and, thus, for a younger age at sexual maturity.
