Article
Full-text available
Connectivity underpins the persistence of life; it needs to inform biodiversity conservation decisions. Yet, when prioritising conservation areas and developing actions, connectivity is not being operationalised in spatial planning. The challenge is the translation of flows associated with connectivity into conservation objectives that lead to acti...

In order to help safeguard biodiversity from global changes, the Convention on Biological Diversity developed a Strategic Plan for Biodiversity for the period 2011-2020 that included a list of twenty specific objectives known as the Aichi Biodiversity Targets. With the end of that timeframe in sight, and despite major advancements in biodiversity c...
Article
Full-text available
Many marine benthic species undergo a pelagic larval stage during which larvae are transported by ocean currents over a broad range of spatial and temporal scales. Although metapopulation theory predicts how stochastic dispersal can alter the stability of metapopulations, little is known about how dispersal-related traits such as spawning time and...
Chapter
Marine protected areas are important tools for the conservation of marine biodiversity, providing refuge for harvested species and mitigating the negative impacts of human activities in marine ecosystems. However, delineating sites for protection within effective MPA networks is a formidable challenge. A primary objective of MPA planning is to opti...

A regional assessment of cumulative impacts is required for the Estuary and Gulf of St. Lawrence to facilitate ecosystem based management supported by evidence. The only currently available assessment was performed at the global scale using 19 drivers of anthropogenic stressors such as fisheries and pollution. While valuable, certain datasets inclu...
Presentation
Full-text available
Describing environmental and anthropogenic drivers of ecosystem change (e.g. hypoxia and fisheries) is largely relying on simplistic metrics that ignore dependencies and the potentially convoluted propagation of effects through complex ecological networks. While informative, such approaches are hardly conducive to robust inference on the impacts of...

Predatory open access (OA) journals can be defined as non-indexed journals that exploit the gold OA model for profit, often spamming academics with questionable e-mails promising rapid OA publication for a fee. In aquaculture-a rapidly growing and highly scrutinized field-the issue of such journals remains undocumented. We employed a quantitative a...
Article
A major objective of marine protected area (MPA) network design is to ensure the persistence of species with diverse life histories and functional traits. Considering how species differ in their propensity to move within and between MPAs is therefore a key consideration for multi-species MPA network design. Here, we propose a conceptual framework t...

Gathering data for large scale, systematic research initiatives such as regional multi-stressor analyses can be a very challenging - not to say painful - process. On one hand, there is an overwhelming wealth of data available, while on the other hand, some required data remain largely unavailable or inaccessible. Coupled with political intricacies,...

Around the world, governments are establishing Marine Protected Area (MPA) networks to meet their commitments to the United Nations Convention on Biological Diversity. MPAs are often used in an effort to conserve biodiversity and manage fisheries stocks. However, their efficacy and effect on fisheries yields remain unclear. We conducted a case-stud...
Article
The ocean provides many benefits, such as food provision, tourism opportunities, and coastal protection, to people around the world. To manage ocean uses in a sustainable way, managers need to limit some activities, but which benefits are most important to preserve? To answer this question, an opinion survey of 2000 Canadians was conducted, combini...

Thesis
Full-text available
This thesis aims to increase our understanding of mechanisms that influence larval dispersal in marine benthic invertebrates, particularly in the absence of strong oceanographic features (e.g. estuarine plumes, upwelling events, or markedly different water masses). Laboratory experiments identified behavioural mechanisms that regulate the vertical...
Article
Larval survival during planktonic dispersal is crucial to the connectivity among benthic populations. Although predation has been suggested as an important cause of larval mortality, this process has rarely been quantified in the field. We measured the abundance of various larval species in the water column in St George’s Bay, Nova Scotia, Canada,...
Article
We examined the effects of the presence of larval conspecifics on larval vertical distribution of four-arm and six-arm plutei of Strongylocentrotus droebachiensis and bipinnaria of Asterias rubens, in laboratory experiments, by manipulating population density. Larvae were introduced to experimental columns (10 × 10 × 30 cm) at one of two or three p...
