Scientists, policy makers and journalists are three key, interconnected players involved in prioritizing implementing solutions to mitigate the consequences of anthropogenic pressures on environment. The way which information is framed expertise communicated by media crucial for political decisions integrated management environmental issues. Here we present a comparative study scientific literature press articles addressing climate change biodiversity. We extensively scrutinized literature,...
Abstract Seaweeds are able to modify the chemical environment at their surface, in a micro‐zone called diffusive boundary layer (DBL), via metabolic processes controlled by light intensity. Depending on thickness of DBL, sessile invertebrates such as calcifying bryozoans or tube‐forming polychaetes living surface blades can be affected variations occurring this microlayer. Especially context ocean acidification (OA), these microhabitats might considered refuge from lower pH, because during...
Marine heatwaves are extreme events that can have profound and lasting impacts on marine species. Field observations shown seaweeds to be highly susceptible heatwaves, but the physiological drivers of this susceptibility poorly understood. Furthermore, effects in conjunction with ocean warming acidification yet investigated. To address knowledge gap, we conducted a laboratory culture experiment which tested growth responses Phyllospora comosa juveniles from southern extent its range...
Over the last few decades, there has been an increasing recognition for seagrasses' contribution to functioning of nearshore ecosystems and climate change mitigation. Nevertheless, seagrass have deteriorating globally at accelerating rate during recent decades. In 2017, research into condition eelgrass (Zostera marina) along eastern coast James Bay, Canada, was initiated in response reports decline by Cree First Nations Eeyou Istchee. As part this research, we compiled analyzed two decades...
Abstract A global decline in seagrass populations has led to renewed calls for their conservation as important providers of biogenic and foraging habitat, shoreline stabilization carbon storage. Eelgrass ( Zostera marina ) occupies the largest geographic range among species spanning a commensurately broad spectrum environmental conditions. In Canada, eelgrass is managed single phylogroup despite occurring across three oceans ocean temperatures salinity gradients. Previous research focused on...
Coralline algae are considered among the most sensitive species to near future ocean acidification. We tested effects of elevated pCO2 on metabolism free-living coralline alga Lithothamnion corallioides ("maerl") and interactions with changes in temperature. Specimens were collected North Brittany (France) grown for 3 months at 380 (ambient ), 550, 750, 1000 μatm (elevated ) successive temperatures 10°C temperature winter), 16°C summer), 19°C summer +3°C). At each temperature, gross primary...
Early life history stages of marine organisms are generally thought to be more sensitive environmental stress than adults. Although most invertebrates broadcast spawners, some species brooders and/or protect their embryos in egg or capsules. Brooding and encapsulation strategies typically assumed confer greater safety protection embryos, although little is known about the physico-chemical conditions within In context ocean acidification, protective role remains investigated. To address this...
The responses of macroalgae to ocean acidification could be altered by availability macronutrients, such as ammonium (NH4+). This study determined how the opportunistic macroalga, Ulva australis responded simultaneous changes in decreasing pH and NH4+ enrichment. was investigated a week-long growth experiment across range predicted future pHs with ambient enriched treatments followed measurements relative rates (RGR), uptake pools, total chlorophyll, tissue carbon nitrogen content. Rapid...
Intensified coastal eutrophication can result in an overgrowth of seagrass leaves by epiphytes, which is a major threat to habitats worldwide, but little known about how epiphytic biofilms affect the phyllosphere. The physico-chemical microenvironment Zostera marina L. with and without epiphytes was mapped electrochemical, thermocouple scalar irradiance microsensors as function four conditions (dark, low, saturating high light) two water flow velocities (approx. 0.5 5 cm s-1), resemble field...
Organisms inhabiting coastal waters naturally experience diel and seasonal physico-chemical variations. According to various assumptions, species are either considered be highly tolerant environmental changes or, conversely, living at the thresholds of their physiological performance. Therefore, these more resistant or sensitive, respectively, ocean acidification warming. Here, we focused on Crepidula fornicata, an invasive gastropod that colonized bays estuaries northwestern European coasts...
Bentho-pelagic life cycles are the dominant reproductive strategy in marine invertebrates, providing great dispersal ability, access to different resources, and opportunity settle suitable habitats upon trigger of environmental cues at key developmental moments. However, free-dispersing larvae can be highly sensitive changes. Among these, magnitude occurrence elevated carbon dioxide (CO2) concentrations oceanic is predicted exacerbate over next decades, particularly coastal areas, reaching...
In the current context of environmental change, ocean acidification is predicted to affect cellular processes, physiology and behaviour all marine organisms, impacting survival, growth reproduction. relation thermal tolerance limits, effects elevated pCO2 could be expected more pronounced at upper limits window. Our study focused on Crepidula fornicata, an invasive gastropod which colonized shallow waters around European coasts during 20th century. We investigated 10 weeks' exposure (380...
Indigenous-driven and community-partnered research projects seeking to develop salient, legitimate, credible knowledge bases for environmental decision-making require a multiple systems approach. When involving partners in addition communities, diverging perspectives priorities may arise, making the pathways engaging principled while generating actionable unclear disciplinarily-trained natural science researchers. Here, we share insights from Eeyou Coastal Habitat Comprehensive Research...
Eelgrass Zostera marina meadows provide valuable ecosystem services to coastal communities. These shallow-water ecosystems in Eeyou Istchee (eastern James Bay, Quebec, Canada) support Cree ways of life by providing waterfowl foraging habitat, fish nurseries, and natural storm buffers. In 2019-2021, eelgrass extent shoot size remained well below historical baseline levels following a major decline the late 1990s. We experimentally tested potential roles present-day nutrient light conditions...
Water quality deterioration is expected to worsen the light conditions in shallow coastal waters with increasing human activities. Temperate seagrasses are known tolerate a highly fluctuating environment. However, depending on their ability adjust some decline conditions, decreases daily quantity and could affect seagrass physiology, productivity, and, eventually, survival if Minimum Quantum Requirements (MQR) not reached. To better understand if, how, what extent photosynthetic adjustments...
