Marine protected areas (MPAs) are important conservation tools for safeguarding marine systems, yet they increasingly impacted by climate change. Connectivity is a fundamental aspect of MPA design and evaluation, but regional patterns ecological connectivity often not well understood, nor how may be affected Our objective was to assess between MPAs shift with projected ocean temperature changes in the Northern Shelf Bioregion British Columbia, Canada, demonstrate potential approach that can used other systems. We conducted case study Dungeness Crab (Metacarcinus magister) Shortspine Thornyhead (Sebastolobus alascanus) using benthic outputs from model hindcast (1981–2010) future (2041–2070) periods coupled species' environmental preference information. evaluated exposure suitability adult stage focal species. Using existing least-cost circuit theory-based more applied terrestrial we identified linkages via movement, simulating both optimal probabilistic paths, then compared interconnectedness time periods. There marked decrease under climates, while there increase minor interconnectedness. Given contrasting results when examining just two species, this highlights challenge building resilience network designs multispecies objectives.

Abstract Technological advancements in data collection and analysis are producing a new generation of ecological data. Among these, computer vision (CV) has received increased attention for its robust capabilities rapidly processing large volumes digital imagery. In marine ecosystems, the study fish connectivity provides fundamental information assessing fisheries stocks, designing implementing protected areas understanding impact habitat loss. While field benefited from technological advancements, extent to which novel techniques, such as CV, have been utilized not assessed. To inform future directions developments, this reviewed current use CV research, quantified how implementation technology research compared with other described could benefit CV.

Abstract Estimates of population structure and gene flow allow exploring the historical contemporary processes that determine a species’ biogeographic pattern. In mangroves, large-scale genetic studies to estimate have been conducted predominantly in Indo-Pacific Atlantic region. Here we examine diversity connectivity Rhizophora mucronata across > 3,000 km coastal stretch Western Indian Ocean (WIO) including WIO islands. Based on 359 trees from 13 populations using 17 polymorphic microsatellite loci detected breaks between (1) East African coastline, (2) Mozambique Channel Area (3) granitic Seychelles, (4) Aldabra northern Madagascar. Genetic structure, levels, patterns inferred connectivity, aligned with directionality major ocean currents, driven by bifurcation South Equatorial Current, northward into Coastal Current southward Area. A secondary break nearby Delagoa Bight coincided high inbreeding levels fixed loci. Results illustrate how oceanographic can connect separate mangrove regardless geographic distance.
