However, algal performance is threatened by climate change and ocean acidification. Previous studies suggest that their photosynthetic performance will be compromised mainly at elevated temperatures. Understanding the impact of diverse climate change scenarios requires a clear and thorough comprehension of the photosynthetic response to temperature gradients. The objective of this study was to evaluate the short-term effect of temperature (10–35 °C) on the gross photosynthesis (GPS), respiration, and electron transport rates (ETRs) of 3 articulated coralline algae (Lithothrix aspergillum, Corallina officinalis, and Bossiella orbigniana) for a better understanding of their metabolism and to investigate the relationship between GPS and ETR as a function of temperature. The results showed that the coralline algal metabolism is highly sensitive to temperature, but responses were species-specific and can be related to their light adaptation/acclimation; the high-light-adapted L. aspergillum was least negatively affected. The photosynthesis to respiration ratio was optimal between 20 and 25 °C according to the local thermal regime but was significantly reduced toward higher temperatures, indicating strong carbon imbalances and highlighting the relevance of thermal stress for coralline algal performance. A strong correlation between GPS and ETR was found between 10 and 30 °C in all species, but both above saturation irradiances and at elevated temperatures (≥30 °C), a clear deviation from linearity occurred. This suggests that ETR is not a good proxy to estimate photosynthetic activity under light or thermal stress. This information should be useful for studies implementing global change scenarios and pulse amplitude modulated (PAM) fluorometry in coralline algae.","PeriodicalId":50702,"journal":{"name":"Ciencias Marinas","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2022-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46346507","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

En total, fueron procesados 1,541 ejemplares, los cuales presentaron una longitud media de 30.30 ± 0.10 cm y un intervalo de longitud de 19.80 a 38.00 cm.

Se encontró correlación significativa entre los valores medios mensuales del índice gonadosomático y el factor de condición relativo. Las gónadas en estadio maduro presentaron ovocitos en 6 fases de desarrollo diferentes y con diámetros de 14.30 a 417.40 µm, lo que supone que el desarrollo de los ovocitos es asincrónico.

A total of 746 spotted dolphin sightings were obtained with a survey effort of 31,695 km. Spotted dolphins in the MCP showed a predominantly coastal distribution regardless of environmental conditions. Significant differences were detected concerning regional seasonal variation, with higher mean sighting rate during the stratified periods and higher density/abundance estimates during the mixed periods. Spotted dolphins showed preference for warmer conditions, with higher mean sighting rate, abundance, and distance to coast during the neutral and warm interannual periods. During the coolest conditions (cold periods), mean sighting rate and abundance decreased and spotted dolphins were located closer to the coast, where Chla concentration increased. These results suggest that changes in the distribution/abundance of these dolphins could be associated with habitat quality related to tropical (El Niño/Southern Oscillation) and extratropical (The Blob) oceanographic phenomena, which could be modulating their foraging activities.","PeriodicalId":50702,"journal":{"name":"Ciencias Marinas","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2022-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43673484","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We developed a bioeconomic model that incorporated the uncertainty for the r and K parameters. We fit 3 models (Schaefer, Fox, and Pella–Tomlinson) to abundance index survey data and used the Akaike information criterion for model selection. The best fit corresponded to the Schaefer model. We built deterministic and stochastic versions of the Gordon–Schaefer model. Economic data (costs and prices) were determined from inter[1]views with fishermen. To estimate the posterior distributions of parameters and indicators, we used Bayesian methods with Markov chain Monte Carlo (MCMC) simulations. The deterministic results suggested that the maximum sustainable income was Mex$851.70 million, with a fishing effort of 3,650 fishing boats, while the maximum sustainable profit was $390.8 million, with a fishing effort of 2,472 fishing boats. The equilibrium point corresponded to an effort of 4,945 fishing boats. Regarding the stochastic model, the MCMC simulation results suggest that the maximum sustainable income distribution was not normal; its average was $856.1 million (SE 1.8) and the most likely value was $849.50 million. The most likely fishing effort at equilibrium was 4,970 fishing boats. Our results suggest the fishery could be operating close to the economic equilibrium point; if this is the case, fishing effort must decrease in order for annual profit to increase. Our approach will help make periodical re-evaluations of the fishery and establish management strategies to ensure the profitable and sustainable exploitation of the red octopus on the Yucatan Peninsula.","PeriodicalId":50702,"journal":{"name":"Ciencias Marinas","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2021-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42469311","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
