Article
Full-text available
To protect cold-water corals and sponges from fishing damage, management changes were made in 2012 to the groundfish bottom trawl fishery British Columbia, Canada. The Groundfish Trawl Habitat Agreement restricted the spatial footprint of the fishery and introduced a cold-water coral and sponge bycatch quota, which was among the world’s first. Usin...
Article
Full-text available
Conservation of marine biodiversity requires understanding the joint influence of ongoing environmental change and fishing pressure. Addressing this challenge requires robust biodiversity monitoring and analyses that jointly account for potential drivers of change. Here, we ask how demersal fish biodiversity in Canadian Pacific waters has changed s...
Article
Asteroids (sea stars) can be important predators in benthic communities and are often present in ecologically important and vulnerable deep-sea coral and sponge habitats. However, explicit studies on the trophic ecology of deep-sea asteroids are rare. We investigated the diets of seven species of deep-sea asteroid from the bathyal zone of Newfoundl...
Article
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 to monitor biodiversity in a synoptic and non-invasive manner. Environmental DNA (eDNA) methods have important advantages over traditional biodiversity survey...
Technical Report
Full-text available
The European Green Crab (EGC) is a high-risk global invader that can devastate coastal marine ecosystems by displacing native species, degrading and disturbing native habitats (including eelgrass), and altering food webs. EGC has recently been detected in the Canadian portion of the Salish Sea. As EGC continue to establish in the region, identifyin...
Technical Report
Full-text available
Canada has committed to establishing a well-connected system of Marine Protected Areas (MPAs) that protect at least 10% of coastal and marine areas by 2020. To advance that goal in the Pacific region, the Government of Canada, Government of British Columbia (BC), and 16 member First Nations are collaborating on marine planning in the Northern Shelf...
Technical Report
Full-text available
Canada is committed to maintaining biological diversity and productivity in the marine environment under the Oceans Act (Government of Canada 1997). Identifying Ecologically and Biologically Significant Areas (EBSAs) is a key component of this commitment. Fisheries and Oceans (DFO) and the Convention on Biological Diversity (CBD) have developed gui...
Article
Cold-water coral and sponge (CWCS) communities are important indicators of vulnerable marine ecosystems (VMEs) and are used to delineate areas for marine conservation and fisheries management. Although the northeast Pacific region of Canada (NEPC) is notable for having unique CWCS assemblages and is the location of >80% of Canadian seamounts, the e...
Technical Report
Full-text available
Conservation priorities (CPs) have been identified as part of systematic conservation planning processes, including Marine Protected Area (MPA) network design, to focus analyses on the most important features (species, habitats, and areas) within a planning area. In this paper, we develop and apply a framework to identify species- and area-based ec...
Article
Full-text available
The Offshore Pacific Bioregion off the west coast of British Columbia, Canada, is a mosaic of mountainous terrain, valleys, ridges, and basins that reflect its intense nearshore tectonic activity. The bioregion is thought to contain 52 underwater mountains (called seamounts) with elevations over 1,000 m, as well as hundreds of smaller knolls and hi...
Technical Report

Canada is committed to maintaining biological diversity and productivity in the marine environment under the Oceans Act (1997). Identifying Ecologically and Biologically Significant Areas (EBSAs) is a key component of this commitment and Fisheries and Oceans (DFO) and the Convention on Biological Diversity (CBD) have developed guidelines and criter...
Presentation
Full-text available
Summary of the cold-water coral and sponge (CWCS) species distribution modelling (SDM) efforts to date. Presents (1) niche separation among major biogenic habitat forming CWCS groups and uses SDM model outputs to spatially test for differences in CWCS habitat suitability among seamounts in the northeast Pacific region of Canada (inside and outside...
Technical Report
Full-text available
As part of the marine protected area (MPA) network planning process in the Northern Shelf Bioregion of B.C. (NSB), the MPA technical team is reviewing 114 existing and 1 proposed marine protected areas to evaluate the degree to which each protected area meets ecological objectives for the network. • Because protected areas vary in their degree of p...
Article
Full-text available
The “area–heterogeneity tradeoff” hypothesis predicts unimodal effects of habitat heterogeneity on species richness, implying that habitats with intermediate heterogeneity may be priority for spatial protection. Alternatively, if heterogeneity effects are positive, then protecting the most heterogeneous habitats may take precedence. We tested for u...

As a signatory to the Convention on Biological Diversity, Canada has committed to conserving 10% of coastal and marine areas into ecologically representative and well-connected marine protected areas (MPAs). The Government of Canada, the Province of British Columbia and 17 First Nations are working together to develop an MPA network in the Northern...
Article
Expansion of oxygen deficient waters (hypoxia) in the northeast Pacific Ocean (NEP) will have marked impacts on marine life. The response of the resident communities will be a function of their ecophysiological constraints in low oxygen, although this remains untested in the NEP due to a lack of integrative studies. Here, we combine in situ surveys...
Article
Data are from lab-based respirometry experiments designed to measure metabolic rates (oxygen consumption) and critical oxygen tensions (O2crit or Pcrit) for slender sole, spot prawn, and squat lobster. Data was collected as part of a PhD thesis (J.W.F. Chu).
Article
Full-text available
Accurate mapping of marine species and habitats is an important yet challenging component of establishing networks of representative marine protected areas. Due to limited biological data, marine classifications based on abiotic data are often used as surrogates to represent biological patterns. We tested the surrogacy of an existing physiographic...
Article
We report new geographical and bathymetric occurrence information for several species of brisingidan asteroids (Asteroidea: Brisingida) in eastern Canada. We recorded Brisinga costata, Freyella microspina and Novodinia americana in Newfoundland and Labrador (NL), extending the geographical ranges of these species northward. Brisinga costata and F....
Article
Although continental shelf and slope environments typically exhibit high epifaunal biomass and have been subjected to increasing fishing pressure, ecological information on assemblages of non-commercial invertebrate species from subtidal and bathyal areas remains limited. Sea stars (Echinodermata: Asteroidea), which are known to influence communiti...

Although they are among the most common mobile megafauna in deep-sea benthic communities, little is known about the ecology of most deep-water asteroids (sea stars). As a first step towards understanding the importance of asteroids in bathyal communities, we present data on the distributions and habitats of species from the continental slope (37-22...
