| log in | [Lobster Larvae Growth and Mortality Data] - Growth and mortality of lobster larvae at different temperatures for lobster larvae from Gulf of Maine near Boothbay Maine from 2021 and 2022 (Lobster Thermal Thresholds project) (RUI: Collaborative Research: Linking physiological thermal thresholds to the distribution of lobster settlers and juveniles) | We used the American lobster (Homarus americanus lsid:marinespecies.org:taxname:156134) in the Gulf of Maine as a model system to define thermal tolerance in larvae and establish mechanistic linkages between thermal tolerance of the individual larva and the patterns of settlement in the field. We assessed and compared the thermal tolerances of larvae reared in the laboratory using conventional methods with larvae captured in the wild, and examined ontogenetic changes in thermal tolerance. The upper and lower thermal thresholds larval stages I-IV and the first juvenile stage were defined in part by growth and mortality when subjected to chronic exposure to different treatment temperatures until they either molted to the next developmental stage or died. This data set includes individuals dying, the size after molting and the amount of time elapsed between the start of the treatment and either molting or death. These data were collected between 2021-2022 at Bigelow Laboratory for Ocean Sciences, led by Eric Annis.\n\ncdm_data_type = Other\nVARIABLES:\nLARVA_ID (unitless)\nTREATMENT_TEMPERATURE (degrees C)\nDIET (unitless)\nREARING_CONDITION (unitless)\nREARING_TEMPERATURE (degrees C)\nDEVELOPMENTAL_STAGE (unitless)\nINDIVIDUAL_LARVA_NUMBER (unitless)\nHATCH_OR_CAPTURE_DATE (unitless)\nTRANSFER_DATE (unitless)\nMOLT_DATE (unitless)\nTIME_UNTIL_MOLT (unitless)\nDEATH_DATE (unitless)\nTIME_UNTIL_DEATH (days)\nCARAPACE_LENGTH (millimeters (mm_)\nDRY_WEIGHT (grams (g))\nNOTES (unitless)\nSource_File (unitless)\n | BCO-DMO | bcodmo_dataset_939825_v1 | ||||||||||||
| log in | [Lobster Larvae Respirometry Data] - Oxygen consumption by lobster larvae at different temperatures using closed cell respirometry for lobster larvae from Gulf of Maine near Boothbay Maine from 2021 to 2023 (Lobster Thermal Thresholds project) (RUI: Collaborative Research: Linking physiological thermal thresholds to the distribution of lobster settlers and juveniles) | We used the American lobster (Homarus americanus lsid:marinespecies.org:taxname:156134) in the Gulf of Maine as a model system to define thermal tolerance in larvae and establish mechanistic linkages between thermal tolerance of the individual larva and the patterns of settlement in the field. We assessed and compared the thermal tolerances of larvae reared in the laboratory using conventional methods with larvae captured in the wild, and examined ontogenetic changes in thermal tolerance. The upper and lower thermal thresholds larval stages I-IV and the first juvenile stage were defined in part by oxygen consumption and scope for activity (defined as the difference in oxygen consumption between larvae at rest and larvae swimming actively). This data set includes the raw oxygen consumption data obtained through closed system microrespirometry and subsequently used to calculate scope for activity. These data were collected between 2021-2023 at Bigelow Laboratory for Ocean Sciences, led by Eric Annis.\n\ncdm_data_type = Other\nVARIABLES:\nLarva_ID (unitless)\nTreatment_Temperature (degrees C)\nDiet (unitless)\nRearing_Temperature (degrees C)\nDevelopmental_Stage (unitless)\nIndividual_Larva_Number (unitless)\nYear (unitless)\nHatch_or_Capture_Date (unitless)\nTrial_Date (unitless)\nTrial_Time_Local_EST (unitless)\ntime (Trial_datetime_utc, seconds since 1970-01-01T00:00:00Z)\nTreatment (unitless)\nO2_Slope (micromole per liter per hour (umol/l/h))\nChamber_Number (unitless)\nChamber_Volume (liters (l))\nTreatment_O2_Consumption (micromole per hour (umol/h))\nControl_O2_Consumption (micromole per hour (umol/h))\nControl_Corrected (micromole per larva per hour (umol/larva/h))\nDry_Weights (milligram (mg))\nO2_Consumption_Normalized (micromole per milligram of larva per hour (umol/mg larva/hr)\n | BCO-DMO | bcodmo_dataset_939782_v1 |
