El objetivo de este trabajo es estudiar los afloramientos localizados en el cerro El Yugo, ubicado en el municipio de Arivechi, noroeste de México, mediante bioestratigrafía de alta resolución basada en foraminíferos. La metodología consiste en la elaboración de secciones delegadas para microfacies así como estudio de óxidos mayores por medio de fluorescencia de rayos X (FRX), además de la extracción de conodontos mediante la disolución de caliza con ácido acético. El estudio documenta la biota presente en las rocas portadoras, lo cual permite realizar una correlación de microfacies, óxidos mayores y biota. Los resultados permiten identificar las biozonas de Nanicella gallowayi, Eogeinitzina devonica, Moravamminidae indet., Tikhinella measpis, Laxoendothyra parakosvensis y Stacheoides tenuis, lo cual permite datar la secuencia en un rango comprendido del Devónico Superior (Frasniano) al Misisípico Inferior-Medio (Tournaisiano-Viseano). El evento de extinción Kellwasser (LKW) del Devónico Superior es identificado en el presente estudio mediante la desaparición de T. measpis y E. devonica en el límite Frasniano-Famenniano. Posterior al Famenniano, la ausencia de biota fósil indica un período de recuperación de ésta.","PeriodicalId":49603,"journal":{"name":"Revista Mexicana de Biodiversidad","volume":" ","pages":""},"PeriodicalIF":0.9,"publicationDate":"2022-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42176150","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We hypothesized that the activity patterns of the jaguar and puma would be biased to the nocturnal period within the cattle ranch but not in the protected areas. We used data from camera traps analyzed through a non-parametric kernel density approach to explore interspecific and intraspecific temporal relationships between these species at both sites. We obtained 71 jaguar and 29 puma independent records at AMR, and 85 jaguar and 26 puma independent records at CR. Activity patterns of jaguars and pumas differed between sites, both being cathemeral in AMR, but nocturnal at CR with moderate to high overlaps, concordant with our hypothesis. Overall, our data suggest that the cattle ranching is not incompatible with the existence of jaguars and pumas but does shape their pattern of activities.","PeriodicalId":49603,"journal":{"name":"Revista Mexicana de Biodiversidad","volume":"1 1","pages":""},"PeriodicalIF":0.9,"publicationDate":"2022-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68149448","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The presence and diversity of testate amoebae were documented in surface sediments and sediment cores, dated with 210Pb, from the only 2 LAMs in Mexico (El Sol and La Luna), which have shown signs of recent human-induced changes. A total of 18 taxa were recorded and the main species observed in both lakes were Difflugia glans “glans” and D. globulosa. Specific richness and Shannon’s diversity index were higher in Lake El Sol than in the smaller, acidic and ultraoligotrophic Lake La Luna. The sediment cores recorded changes, during the last 20 to 25 years, in the composition of the testate amoebae communities (El Sol) and in their dominance (La Luna), as well as increased accumulation rate and concentrations of iron and organic carbon. These are signs of anthropogenic impact on the lakes, which should alert us to improve protection measures for these unique ecosystems, not only at the local (crater) level, but also with a more regional perspective.","PeriodicalId":49603,"journal":{"name":"Revista Mexicana de Biodiversidad","volume":" ","pages":""},"PeriodicalIF":0.9,"publicationDate":"2022-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46397965","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We built environmental layers for national, regional, and local scales, considering the different scales studies can have. We used a numerical classification of explicit spatial layers and performed a multivariate classification. Based on the domains obtained, we mapped the landscape’s climatic heterogeneity and identified a comprehensive set of environmental variables that defined the landscape matrix at each scale. We specifically tested our approach for its suitability to define a sampling strategy for a landscape genetics study, using as focal species the rodent Heteromys pictus. Namely, from the domains obtained at the local scale, we selected sampling localities that comprised the broadest habitat heterogeneity, which we corroborated in the field. The landscape matrix thus generated was used with genetic data previously obtained for H. pictus. Our approach allowed identification of environmental variables significantly associated with dispersal (gene flow) of H. pictus individuals in their natural habitat. We demonstrate its adequacy to efficiently determine sampling localities —or landscape sites— that encompass the highest environmental heterogeneity, in explored and unexplored landscapes, enabling rapid identification of localities and their environmental characteristics where in situ information is scarce.","PeriodicalId":49603,"journal":{"name":"Revista Mexicana de Biodiversidad","volume":" ","pages":""},"PeriodicalIF":0.9,"publicationDate":"2022-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48548833","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Se utilizaron 70 sitios de muestreo de 500 m2 distribuidos en 3 diferentes tipos de vegetación (encinar, pino-encino y matorral xérico). En cada sitio se inventariaron todos los árboles y arbustos > 1 m de altura. Se registraron 92 especies leñosas, incluidos 62 arbustos, 28 árboles y 1 especie de palmera del género Brahea. Los resultados indican que existe una estrecha asociación entre tipos de vegetación y especies con varios elementos de geodiversidad, principalmente temperatura, precipitación, altitud y factores de perturbación antrópica. Por otro lado, la composición florística está dominada por especies generalistas (70%), lo que sugiere una etapa sucesional secundaria y un ambiente antropizado.
