Semantic Segmentation of Coral Reefs Using Convolutional Neural Networks: A Case Study in Kiritimati, Kiribati Open
Habitat complexity plays a critical role in coral reef ecosystems by enhancing habitat availability, increasing ecological resilience, and offering coastal protection. Structure-from-motion (SfM) photogrammetry has become a standard approa…

Carbon pathways and trophic attributes are conserved in carnivorous reef fishes across a major human disturbance gradient Open
Habitat degradation and overexploitation are key drivers of biodiversity loss globally. Negative, human‐driven changes in habitat quality, species abundance, and community composition are well‐documented across systems. While it is underst…

Added value of a priori bias correcting dynamically downscaled data for application to species distribution models - a case study for coastal British Columbia Open
Predicting changes in species distributions under climate change relies on high-quality climate projections. In this case study of coastal British Columbia, we prepare and evaluate two sets of climate data - a priori bias corrected and non…

Testing the roles of local adaptation and genetic diversity to improve Giant kelp (<i>Macrocystis pyrifera</i>) restoration Open
Climate change is causing significant losses of coastal foundation species globally, heightening the need for their restoration. Despite the urgency, it remains unclear if enhancing genetic diversity by using distant source populations wil…

A blueprint for national assessments of the blue carbon capacity of kelp forests applied to Canada’s coastline Open
Kelp forests offer substantial carbon fixation, with the potential to contribute to natural climate solutions (NCS). However, to be included in national NCS inventories, governments must first quantify the kelp-derived carbon stocks and fl…

Impacts of a prolonged marine heatwave and chronic local human disturbance on juvenile coral assemblages Open
Coral reefs are threatened by climate change and chronic local human disturbances. Although some laboratory studies have investigated the effects of combined stressors, such as nutrient enrichment and heat stress, on growth and survival of…

Spatial variation in benthic community composition on a minimally disturbed coral reef in the years following a prolonged marine heatwave Open
With the increased frequency of marine heatwaves and related coral mass mortality events, it is imperative that we improve our understanding of coral reef recovery processes including how benthic community compositions can change over time…

Host traits and temperature predict biogeographical variation in seagrass disease prevalence Open
Diseases are ubiquitous in natural systems, with broad effects across populations, communities and ecosystems. However, the drivers of many diseases remain poorly understood, particularly in marine environments, inhibiting effective conser…

Impacts of Climate Change on Marine Foundation Species Open
Marine foundation species are the biotic basis for many of the world's coastal ecosystems, providing structural habitat, food, and protection for myriad plants and animals as well as many ecosystem services. However, climate change poses a…

Ocean weather, biological rates, and unexplained global ecological patterns Open
As on land, oceans exhibit high temporal and spatial temperature variation. This "ocean weather" contributes to the physiological and ecological processes that ultimately determine the patterns of species distribution and abundance, yet is…

Mobile bottom fishing in the Canadian Pacific and Atlantic causes disturbance and risk to remineralisation of seabed sediment carbon stocks Open
Mobile bottom fishing causes substantial disturbances to seabed sediments–one of the world’s largest organic carbon stores. We estimate that 2.1 and 32.0 Mt of carbon is disturbed by annual fishing activities in the Canadian Pacific and At…

Protection of seabed sediments in Canada's marine conservation network for potential climate change mitigation co-benefit Open
Marine conserved areas (MCAs) can provide a range of ecological and socio-economic benefits, including climate change mitigation from the protection and enhancement of natural carbon storage. Canada's MCA network is expanding to encompass …

Predation scars provide a new method to distinguish native and invasive crab predation on mollusc prey Open
Crab species are increasingly important socioeconomic resources that are threatened by human exploitation, climate change, and invasive species, such as European green crabs ( Carcinus maenas ). However, the continued health of their popul…

A framework for optimising opportunistic collaborative syntheses to propel ecological conservation Open
Ecological data are being opportunistically synthesised at unprecedented scales in response to the global biodiversity and climate crises. Such syntheses are often only possible through large-scale, international, multidisciplinary collabo…

Variation in estuary use patterns of juvenile Chinook salmon in the Fraser River, BC Open
Juvenile Pacific salmon ( Oncorhynchus spp.) use estuary habitats to varying degrees with some species and populations thought to rely heavily on these areas for early growth. In the Fraser River, British Columbia, there are 18 distinct co…
