Few studies have evaluated the joint effects of elevated temperature and pCO2 on marine organisms. In this study we investigated interactive Intergovernmental Panel Climate Change predicted for end 21st century key aspects larval development American lobster, Homarus americanus, an otherwise well-studied, iconic, commercially prominent species in northeastern United States Atlantic Canada. Our experiments showed that larvae (stages I–III) postlarvae (stage IV) reared high treatments (19 °C)...
Abstract The American lobster (Homarus americanusMilne Edwards, 1837) is an ecologically and economically valuable invertebrate in the Northwest Atlantic. Its geographic range shifting northward due to ocean warming. While extensive research on thermal tolerance of this species has been performed adults postlarvae, there have few studies focused its multiple early developmental stages. We applied transcriptomics investigate transcriptional changes laboratory-reared stages I through V....
Physiological response to temperature stress defines the distribution of many marine invertebrates, and their thermal limits provide a foundation for understanding invertebrate climate change. In bottom dwelling species with free swimming planktonic larvae, such as American lobster (Homarus americanus), tolerance early life stages influences vertical in water, settlement patterns on bottom, ultimately species' range. We used measures scope activity, size, survivorship, molecular techniques...
Abstract The planktonic larvae of the American lobster (Homarus americanus H. Milne Edwards, 1837) in Gulf Maine typically hatch summer and are sensitive to conditions water column including temperature, salinity, prey availability. Their ability survive at this stage has both ecological economic impacts New England states disproportionately Maine. While monitoring surveys for all other life stages have occurred consistently throughout Maine, understanding density seasonality larval supply...
Abstract The Maine Department of Marine Resources (MEDMR) is a state agency tasked with developing, conserving, researching, and promoting commercial recreational marine fisheries across Maine’s vast coastline. Close collaborations industry members in each the 30 or more that support coastal economy are central to MEDMR’s efforts address this suite tasks. Here we reflect on recent decades MEDMR's work demonstrate how MEDMR research programmes preparing for an uncertain future through lens...
Abstract The carapace length (CL) at which American lobster (Homarus americanus) females reach maturity can be used to evaluate egg production, growth patterns, and the overall health of stocks. female datasets represent Gulf Maine (GOM) lobsters in 2015 Atlantic States Marine Fisheries Commission Lobster Stock Assessment were collected 1990s by Department Resources two coastal sites. Many studies have demonstrated an inverse relationship between temperature size lobsters, GOM waters warmed...
The most common biomineral produced in the contemporary ocean is calcium carbonate, including polymorph calcite by coccolithophores. surface waters of are supersaturated with respect to carbonate. As a result, particulate inorganic carbon (PIC), such as coccoliths, not expected thermodynamically dissolve above lysocline (~4500-6000 m). However, observations indicate that up 60-80% carbonate lost upper 500-1000 m ocean. This hypothesized occur microenvironments reduced saturation states,...
Abstract Anthropogenic carbon emissions released into the atmosphere is driving rapid, concurrent increases in temperature and acidity across world's oceans. Disentangling interactive effects of warming acidification on vulnerable life stages important to our understanding responses marine species climate change. This study evaluates these stressors acute response gene expression postlarval American lobster ( Homarus americanus ), a whose geographic range acidifying faster than most In...
The American lobster ( Homarus americanus ) is an economically important species in the western Atlantic and its climate-driven range shift northward along east coast of United States well documented. thermal tolerance lab-reared postlarvae this has been extensively investigated to better understand settlement recruitment dynamics. However, there have few studies focused on wild-caught postlarvae, even fewer that analyzed lab-rearing conditions context diet. In study, we gene transcriptional...
ABSTRACT The size at which female American lobsters Homarus americanus (H. Milne Edwards, 1837) reach maturity was determined for females collected from inshore (< 3 nautical miles, or 5.5 km) Boothbay Harbor (BBH), Maine, USA in 2018. A total of 272 were during a three-week period the spring and each assigned status (immature mature) based on ovarian staging. These determinations then compared to two similar female-maturity studies undertaken BBH by Maine Department Marine Resources over...
The degree to which human actions affect marine fisheries has been a fundamental question shaping people’s relationship with the sea. Today, divergences in stakeholder views about impacts of activities such as fishing, climate change, pollution, and resource management can hinder effective co-management adaptation. Here, we used surveys construct mental models Maine lobster fishery, identifying divergent held by two key groups: fishers scientists. groups were differentiated their perceptions...
