RUI: Collaborative Research: Linking physiological thermal thresholds to the distribution of lobster settlers and juveniles https://osprey.bco-dmo.org/project/845227 RUI: Collaborative Research: Linking physiological thermal thresholds to the distribution of lobster settlers and juveniles <p><em>NSF Award Abstract:</em><br /> Temperature is one critical factor that determines the distribution of marine organisms. However, in many cases temperature ranges (thermal tolerances) are only known for adults, but not for the immature stages that transition from the plankton to the bottom. This study is testing how temperature affects where larvae are settling. The American lobster (Homarus americanus) in the Gulf of Maine is serving as a model system to measure the thermal tolerance of the larvae and link this to the distribution of young lobsters in the field. Presently, lobster larvae are more likely to experience relatively cold temperatures than heat stress and larval settlement appears to be restricted to warmer shallow waters by a sensitivity to temperatures below 12°C. As water temperature has increased, settlement and juvenile distribution have expanded into deeper waters suggesting a release from cold stress. This project is advancing the understanding of shifting species distributions in response to increasing ocean temperatures by exploring thermal sensitivity in wild-caught larvae for the first time. This information is providing thermal thresholds for modeling larval viability in response to climate change scenarios. Understanding the larvae?s responses to temperature is fundamental to predicting the impact of climate change on one of the most valuable commercial fisheries in North America. The project is supporting training of undergraduate interns and a master?s student from small colleges (Hood College and University of New England) and connecting them with a research institution (Bigelow Laboratory for Ocean Sciences). Teacher training is occurring in collaboration with the Marine Science Center at the University of New England. Results from this study are being shared with stakeholders and contributing to science-based management of the lobster fishery.</p> <p>This project is the first to examine how thermal stress on a larval stage determines juvenile distributions using a combination of correlative and experimental approaches that includes measuring biochemical stress indicators in larvae deployed in natural field habitats. The central hypothesis is that the physiology of individual planktonic larvae controls meso-scale settlement patterns in the field. The goal is to ascertain if there is a causal relationship between the underlying physiology and thermal sensitivity of the organism and the distribution of early life stages. Larval supply, settlement and juvenile abundances will be assessed at different depths with temperatures above and below the proposed minimum temperature threshold of 12°C for larvae. Laboratory experiments using conventional methods are determining thermal tolerances in wild-caught larvae and how they change with ontogeny. The upper and lower thermal optima are being resolved using multiple physiological parameters such as measurements of oxygen consumption and aerobic scope, and biochemical assays of thermal stress (HSP70, AMPK, and SIRT). To link physiology to settlement patterns, caged stage IV larvae and V juveniles are being deployed in the field at sites with temperatures above and below 12°C. Lethal and sub-lethal effects on caged lobsters are being evaluated through measures of growth, mortality and biochemical markers of thermal stress. This is the first study to focus on the thermal tolerance of wild larvae, which has broad implications for understanding settling in marine invertebrate larvae.</p> Lobster Thermal Thresholds largerWorkCitation project eng; USA oceans -69.7615 -69.5025 43.6558 43.8453 2023-06-02 2023-09-29 Gulf of Maine 0 BCO-DMO catalogue of parameters from Water temperature data from temperature loggers attached to larval settlement collectors placed on the seafloor in the Gulf of Maine from from June to September 2023 (Lobster Thermal Thresholds project) Biological and Chemical Oceanography Data Management Office (BCO-DMO) Unavailable 508-289-2009 WHOI MS#36 Woods Hole MA 02543 USA info@bco-dmo.org http://www.bco-dmo.org Monday - Friday 8:00am - 5:00pm For questions regarding this resource, please contact BCO-DMO via the email address provided. pointOfContact http://lod.bco-dmo.org/id/dataset-parameter/957592.rdf Name: ISO_DateTime_UTC Units: unitless Description: <p>Date time of the sensor reading from the data collector in UTC.</p> http://lod.bco-dmo.org/id/dataset-parameter/957593.rdf Name: Ch1_Temperature Units: degrees C Description: <p>Temperature reading from the sensor of the data collector.</p> http://lod.bco-dmo.org/id/dataset-parameter/957594.rdf Name: Collector_ID Units: unitless Description: <p>Sequential number given to each larval settlement collector.  This corresponds to the collector number in the file name.</p> http://lod.bco-dmo.org/id/dataset-parameter/957595.rdf Name: Temperature_Logger_ID Units: unitless Description: <p>Serial number of the individual temperature logger in the collector.  It is also included in the file name in corisponding the Source_File value.</p> http://lod.bco-dmo.org/id/dataset-parameter/957596.rdf Name: Latitude Units: decimal degrees Description: <p>Latitude of logger deployment location in decimal degrees; a positive value indicates a northern coordinate.</p> http://lod.bco-dmo.org/id/dataset-parameter/957597.rdf Name: Longitude Units: decimal degrees Description: <p>Longitude of logger deployment location in decimal degrees; a negative value indicates a western coordinate.</p> http://lod.bco-dmo.org/id/dataset-parameter/957598.rdf Name: Datetime_deployed_UTC Units: unitless Description: <p>Date time the data collector was deployed for data collection.</p> http://lod.bco-dmo.org/id/dataset-parameter/957599.rdf Name: Date_Retrieved_UTC Units: unitless Description: <p>The date that the collector and teperature logger were retrieved from the bottom. &quot;LOST&quot; in this field indicates that the collector was not retrieved.</p> http://lod.bco-dmo.org/id/dataset-parameter/957600.rdf Name: Depth Units: meters (m) Description: <p>Deployments were made from a commercial fishing vessel; depth data were recorded in fathoms and converted to meters.</p> http://lod.bco-dmo.org/id/dataset-parameter/957601.rdf Name: Source_File Units: unitless Description: <p>Original file name from which the corresponding row of data was sourced.
