These include processing seafood products, harvesting or direct capture of species, and the sale of these products. In recent years, the decline of marine species has motivated them to also implement activities for the conservation of marine ecosystems such as reforestation, waste separation, and proper resource management, among others. Despite this, their work is little recognized and undervalued. Considering this, the objective of this work is to identify and describe the role of women in artisanal fishing in Celestún, Mexico. A qualitative methodology based on the application of semi-structured interviews was used for this purpose. In the fieldwork we observed that in Celestún, power relations influence access to marine resources, which directly impacts the economic and food security of families. Women are confronted with machista attitudes in the community, which limits them when carrying out different economic activities. This can affect their economic income and is detrimental to their families and the community in general. \u0000Keywords: woman, role of women, fishing, sustainability, artisanal fishing, gender equality, Celestún.","PeriodicalId":262347,"journal":{"name":"JAINA Costas y Mares ante el Cambio Climático","volume":"174 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133614710","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The presence of hard structures of anthropogenic origin along the coasts can also create static artificial margins between land and sea, restricting coastal habitats to a narrow area. Ground level rise with respect to the coastal plain, which can be caused by an interrupted hydro-sedimentary flow, can also form added natural barriers. In particular, the coast of Mexico is vulnerable to sea level rise, however, other faster processes could be inducing coastal oppression/squeeze to a greater extent, such as subsidence, extreme hydrometeorological phenomena, changes in land use and erosion derived from sediment retention in the upper coastal basins. The aim of this study is analyzed coastal oppression along the coast for Ciudad del Carmen, Campeche, Mexico, by finding its determining variables based on a literature review and analysis of open access databases. The processes analyzed correspond to changes in land use, the incidence of storms and the presence of hard structures, among other factors, which have increased rapidly in the study area in recent years and have caused the loss of coastal ecosystems. Ultimately, this work aims to generate a method that can quantitatively measure the effects of coastal oppression in different coastal areas.

The possible responses of these parasitic infections to changes in the aquatic ecosystems caused by anthropogenic climate change are described. By studying the intensity of infection of Argulus yucatanus (a case study of parasite crustaceans of fish), the response of infections to changes in water temperature can be detected. Into this context and based on previous investigations reviewed, it is highlighted the importance of monitoring for long-time the behavior of these parasites. Also, it is indicated that parasitic crustaceans represent a good study model as bioindicators of environmental changes because they are in direct contact or exposed to hazardous substances of the environment. Extensive and precise data on parasitic biodiversity along with their ecological and experimental information are necessary to understand the possible responses of the parasitic infections caused by crustaceans in the face of climate change. Based on this kind of information it would be possible to deal with issues on control strategies and prevention of parasitic infections caused by crustaceans in aquaculture as well as for the sustainable development of aquatic ecosystems.\u0000Keywords: Long-term monitoring, sentinel species, parasitic infections, parasitic crustaceans, climate change.","PeriodicalId":262347,"journal":{"name":"JAINA Costas y Mares ante el Cambio Climático","volume":"190 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124286840","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These events have been attributed to factors physical, chemical and biological. In addition, honey bee and their products are considered key tools in the evaluation of the health of ecosystems, since are a group of organism are in direct contact with environmental and anthropogenic factors such as pollutants. Pesticides like organochlorines (OCPs) are considered persistent organic pollutants, extremely toxic and dangerous for humans and bees, because can cause neurotoxicity and immunotoxicity, like as mutations, cancer and death. To mitigate the adverse effects of pollutants, vertebrates and invertebrates have detoxification systems conformed by various enzymatic pathways. However, in A. mellifera, the number of genes that involved these enzymes is limited. It has been documented, the suitable immune pathways activation of A. mellifera is essential to combat xenobiotics and pathogens such as viruses, bacteria, and protozoa. This activation starts when Pattern Recognition Receptors (PRRs) detect the Pathogen Associated Molecular Patterns (PAMPs) or Damage Associated Molecular Patterns (DAMPs). Signalling pathways include toll, JAK/STAT, RNAi, Imd, JNK, and melanization including prophenoloxidase (proPO). Few studies have been aimed at assessing the effects of OCPs on A. mellifera. Although pesticides are known to have genotoxic effect on immune system genes like AMPs, abaecin, hymenoptaecin, apisimin, defensin, lysozyme, TOLL, PCE, relish, hopscotch, domeless, NF-kB, spaetzle, cactus, dorsal, basket and proPO. Moreover, pathogenic infection showed alteration in the expression of the genes that code for JNK/bsk, p53, iap-2, caspase, NF-kB, Toll, Tube and Tep-B. In this sense, the identification of key genes alteration of the immune system as a response against pathogens would allow the determination of sensitive biomarkers of OCPs, as well as the evaluation of their impact on A. mellifera and the ecosystem health. Therefore, this review highlights the importance of the immune response of the honey bees A. mellifera, focused in the activation pathways and the genotoxic impact of the OCPs.\u0000Keywords: Apis mellifera, organochlorine pesticides (OCPs), genotoxicity, immunotoxicity.","PeriodicalId":262347,"journal":{"name":"JAINA Costas y Mares ante el Cambio Climático","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121820791","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, in the last 20 years it has been influenced by anthropic and natural impacts, which modifies the physicochemical characteristics of the water (temperature, salinity and pH) and changes in diversity species, being decisive in changes in regionalization. Therefore, in the present study, the spatio-temporal relationship of the physicochemical characteristics was analyzed, using geostatistics to characterize and predict possible new hydrological zones for Terminos lagoon. Samples were carried out monthly at 17 points, by zones and seasons (dry, rainy and wind/winter), in which significant differences were sought. To detect possible changes in regionalization, the GS+ software was used, where the values ​​of R2 were considered, defining the interpolation of Minimum Curvature (R2 <0.5). For the spatial distribution, the TNTmips program was used and to restructure the current zoning, a Cluster Analysis was applied. The results indicate for rainy season higher temperature values ​​(30.59 °C), higher salinity in dry (31.78 UPS), and higher pH in the wind/winter season (7.88). In the spatial distribution, the warmest areas were shown in the Candelaria River, the most saline areas by Isla de Carmen and the highest pH ranges near Pom-Atasta.

It is also the site of various anthropogenic activities in the lagoon as well as in its surroundings. In addition, in recent years this lagoon has showed variations in temperature and salinity as a result of global warming and/or watershed management. This has generated variations in the structure and function of fish communities, among other taxonomic groups. IIn this work, we analyze the changes in abundance and distribution associated with modifications in the salinity of fish species from two key families (Ariidae y Gerreidae) during the years 1980, 1998, and 2011. Salinity is analyzed in the three periods (ANOVA, Tukey (HSD); the abundance of species, environmental breadth according to salinity (Levins Index), environmental overlap (Pianka Index), and co-occurrence (C-score) are also analyzed. Statistical differences were tested using the null model. The results showed high variability in salinity, with a tendency to increase during the studied period with 24.7, 27.9, and 28.4 UPS for each year, respectively (p < 0.0001). The abundance of both families increased from 1980 to 1998 and decreased in 2011 (82% for Ariidae and 62% for Gerreidae). The C-score ranged from 1.07 in 1980 to 0.78 in 1998 and 2.71 in 2011. The observed averages were significantly lower than the simulated average (P <0.0001). In conclusion, the increase in salinity is probably one of the causes of a variation in the abundance of fish species.

The objective was to analyze the trophic role (amplitude, overlap and trophic level) through the stomach content and its possible relationship with the morphological aspects of L. rhomboides. and A. rhomboidalis during three climatic seasons (30 individuals per species per season). As results, 180 individuals were analyzed with an average total length of 14.0 ± 2.5 (cm) for both species. According to the Index Importance Geometric (IGI), Thalassia testudinum was the main item of L. rhomboides (IGI= 86.3) and A. rhomboidalis (IGI= 63.3), however, the secondary items for A. rhombiodalis (Brachidontes (Hormomya) exustus= 5.70) and L. rhomboides (Parvilucina (Parvilucina) multilineata= 16.80) were different. The trophic breadth (“Bi”) indicated that L. rhomboides. and A. rhomboidalis are specialists (BiLr= 0.02 and BiAr= 0.01). At the intraspecific level, there is high similarity (ANOSIM) in the diet of both Sparids between seasons (RLr= 0.03 and RAr= 0.05), however, at the interspecific level, low similarity was observed (Rg= 0.15), which was reflected in the NT of both Sparids (NTLr= 2.22 and NTAr= 3.71).
