Foraging behavior of Critically Endangered North Atlantic right whales is associated with ambient noise, prey density, and the acoustic behavior of conspecifics

Robert S. Schick, Tina M. Yack, Enrico Pirotta, Charles A. Mayo et autres

The endangered North Atlantic right whale (NARW) faces threats from lethal and sublethal stressors. Prey limitation has been linked to reduced growth and fecundity, while anthropogenic noise has been associated with acoustic behavior changes and increased physiological stress. We combined disparate data …

Author response for "A synthesis of the effects of multiple stressors on a long-lived vertebrate population to inform effective conservation efforts"

An experimental approach to assess the combined effects of multiple stressors on a large vertebrate species

Enrico Pirotta, Catriona M. Harris, Lori H. Schwacke, Len Thomas et autres

The design of experiments to investigate the combined effects of multiple stressors requires exposing target organisms to multiple combinations of stressor doses. Concurrent manipulation of stressors is often infeasible with wildlife, but long-lasting health effects allow individual health to be used as …

Methods for analysing wildlife DNA methylation data

Theoni Photopoulou, Ian N. Durbach, Enrico Pirotta, Ashley Barratclough et autres

Abstract The analysis of DNA methylation data for wildlife conservation is gaining momentum as the technology for quantifying the methylome becomes mainstream. The use of epigenetic information extracted from tissue samples can be used for estimating chronological age, individual traits and phenotypic …

The combined effects of multiple stressors in an endangered, long‐lived species: Lessons learned and ways forward

Enrico Pirotta, Peter Lloyd Tyack, Jeffrey Adams, Michael J. Asaro et autres

Exploring solutions to expanding industrial activities and climate change requires assessments of the combined effects of multiple stressors on wildlife populations. We present a spatially explicit state-space model for the health, survival, reproduction, and somatic growth of individuals in a long-lived, wide-ranging …

A synthesis of the effects of multiple stressors on a long-lived vertebrate population to inform effective conservation efforts

Enrico Pirotta, Len Thomas, Peter Tyack, Catriona M. Harris et autres

This repository contains the code and data needed for the development of a population consequences of multiple stressors (PCoMS) model for the population of bottlenose dolphins in Barataria Bay, Louisiana USA

Decreasing body size is associated with reduced calving probability in critically endangered North Atlantic right whales

Enrico Pirotta, Peter Lloyd Tyack, John W. Durban, Holly Fearnbach et autres

Body size is key to many life-history processes, including reproduction. Across species, climate change and other stressors have caused reductions in the body size to which animals can grow, called asymptotic size, with consequences for demography. A reduction in mean asymptotic length …

Behavioural responses of fin whales to military mid-frequency active sonar

Brandon L. Southall, Ann N. Allen, John A. Calambokidis, Caroline B. Casey et autres

The effect of active sonars on marine mammal behaviour is a topic of considerable interest and scientific investigation. Some whales, including the largest species (blue whales, Balaenoptera musculus ), can be impacted by mid-frequency (1–10 kHz) military sonars. Here we apply complementary …

Continuous-time modelling of behavioural responses in animal movement

Théo Michelot, Richard Glennie, Len Thomas, Nicola J. Quick et autres

There is great interest in ecology to understand how wild animals are affected by anthropogenic disturbances, such as sounds. For example, behavioural response studies are an important approach to quantify the impact of naval activity on marine mammals. Controlled exposure experiments are …

Estimating the effects of stressors on the health, survival and reproduction of a critically endangered, long‐lived species

Enrico Pirotta, Robert S. Schick, Philip K. Hamilton, Catriona M. Harris et autres

Quantifying the cumulative effects of stressors on individuals and populations can inform the development of effective management and conservation strategies. We developed a Bayesian state–space model to assess the effects of multiple stressors on individual survival and reproduction. In the model, stressor …

Managing the effects of multiple stressors on wildlife populations in their ecosystems: developing a cumulative risk approach

Peter Lloyd Tyack, Len Thomas, Daniel Pereira da Costa, Ailsa J. Hall et autres

Assessing cumulative effects of human activities on ecosystems is required by many jurisdictions, but current science cannot meet regulatory demands. Regulations define them as effect(s) of one human action combined with other actions. Here we argue for an approach that evaluates the …
