The impacts of climate change and the socioecological challenges they present are ubiquitous increasingly severe. Practical efforts to operationalize climate-responsive design management in global network marine protected areas (MPAs) required ensure long-term effectiveness for safeguarding biodiversity ecosystem services. Here, we review progress integrating adaptation into MPA provide eight recommendations expedite this process. Climate-smart objectives should become default all areas,...
The endangered leatherback turtle is a large, highly migratory marine predator that inexplicably relies upon diet of low-energy gelatinous zooplankton. location these prey may be predictable at large oceanographic scales, given turtles perform long distance migrations (1000s km) from nesting beaches to high latitude foraging grounds. However, little known about the profitability this migration and strategy. We used GPS data video animal-borne cameras examine how characteristics (i.e., size,...
The use of small unoccupied aircraft systems (UAS) for ecological studies and wildlife population assessments is increasing. These methods can provide significant benefits in terms costs reductions human risk, but little known if UAS-based approaches cause disturbance animals during operations. To address this knowledge gap, we conducted a series UAS flights at gray seal breeding colonies on Hay Saddle Islands Nova Scotia, Canada. Using fixed-wing UAS, assessed both immediate short-term...
Optimal diving theory predicts that animals make decisions maximize their foraging profitability subject to the constraint of oxygen stores. We examined temporal pattern prey encounters within a dive from concurrently collected data and animal-borne video free-ranging pinniped test predictions optimal theory. Crittercams were deployed on 32 adult male harbour seals (Phoca vitulina concolor De Kay, 1842) at Sable Island, Nova Scotia, Canada, for 3 days each. Deployments resulted in...
Abstract Understanding habitat requirements for species at risk is crucial effective conservation management, even though the location and extent of vital habitats may be unknown rare or elusive species. In case marine species, determining important often relies on limited occurrence data extrapolation from distribution models (SDMs). SDMs predict by associating records with environmental variables, assuming a functional ecological relationship. This study focuses northern bottlenose whales...
Nine prey species (n = 7431) were fed to four captive female Steller sea lions ( Eumetopias jubatus (Schreber, 1776)) in 11 feeding trials over 75 days investigate the effectiveness of different methods used determine diet from hard remains. Trials aimed replicate short (1–2 days) and long bouts, consisted single mixed daily diets. Overall, 25.2% ± 22.2% (mean SD, range 0%–83%) otoliths recovered, but recovery rates varied by (ANOVA, P 0.01) linearly related otolith robustness (R 2 0.88)....
Marine Protected Areas (MPAs) have been adopted globally as a tool to combat biodiversity loss and restore marine ecosystems. Successful application of MPAs will be predicated on the ability monitor in synoptic noninvasive manner. Environmental DNA (eDNA) methods important advantages over traditional survey for monitoring conservation areas. To evaluate efficacy eDNA metabarcoding fish monitoring, we sampled 19 coastal eelgrass (Zostera marina) beds Canada, are known high significant value....
Reliable estimates of diets are vital to monitor impacts sea lion populations on their ecosystems and interactions with fisheries, understand the role food animal nutrition health. Approaches include using (1) prey remnants in stomach contents, spews scats; (2) DNA (3) fatty acid signatures blubber; (4) stable isotope ratios predator’s tissue. Each methodology has particular advantages limitations, many which can be assessed improved through controlled captive feeding trials. Analysis from...
Abstract Marine classification schemes based on abiotic surrogates often inform regional marine conservation planning in lieu of detailed biological data. However, these may poorly represent ecologically relevant patterns required for effective design and management strategies. We used a community‐level modeling approach to characterize delineate representative mesoscale (tens thousands kilometers) assemblages demersal fish benthic invertebrates the Northwest Atlantic. Hierarchical...

Although the use of animal-borne video cameras has brought great insight into lives animals, there are still several limitations in using them to record observational data. The ethical demand for reduced camera size limits battery capacity, which thus restricts recording duration. In addition design considerations, sampling options available extending duration following tag deployment. These include duty cycling (for at preset times), a depth trigger and varying interval between images. We...
