In this study, saprotrophic fungi from a disturbed Juniperus deppeana forest were isolated and identified for in vitro propagation. Thirty-one specimens were collected and propagated on malt extract agar (EMA), potato dextrose agar (PDA), Kraft lignin agar (A-L) and mineral medium (MM). Taxonomic identification was performed on the basis of macro- and micromorphological characters of the basidiomata, and was complemented by phylogenetic analysis of ITS sequences. Only 7 strains grew under in vitro conditions; they grew best in EMA and PDA media. Room temperature (~22 °C) and preservation at 4 °C were the best conditions to maintain the viability of the strains. After 6 months, strains preserved in glycerol (15%) at 4° and -20 °C were not viable. The isolated fungi belong to the genera Agrocybe, Byssomerulius, Coniophora and Gymnopus. Given the environmental conditions where the strains were isolated, they represent new research prospects for obtaining biomolecules of biotechnological interest.","PeriodicalId":49603,"journal":{"name":"Revista Mexicana de Biodiversidad","volume":"37 1","pages":""},"PeriodicalIF":0.9,"publicationDate":"2023-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138595578","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}

Para ésto, se caracterizaron las comunidades vegetales presentes y se generaron clasificaciones supervisadas de cobertura con imágenes satelitales de mediana y alta resolución para realizar un análisis cambio de la cobertura vegetal (2003-2018). Las precisiones generales de las clasificaciones fueron iguales o superiores a 0.75, valor que aumentó al utilizar imágenes de mayor resolución espacial. El uso combinado de diferentes resoluciones espaciales presentó ventajas para entender las transiciones de composición entre diferentes comunidades vegetales.

However, we lack information about the climatic conditions birds are tracking, especially in intratropical migrants, whose movements are contained inside the tropics. The Yellow-green Vireo Vireo flavoviridis is an intratropical migrant whose migration patterns remain only partially documented and understood. Using GBIF presence records and WorldClim monthly climatic layers, we reconstructed ecological niche for Yellow-green Vireo’ reproductive and non-reproductive seasons. Then, we used a niche overlap analysis, based on a PCA-env approach and similarity tests, to assess overlap in climatic niches between seasons. We also projected climatic niches onto their spring and fall migration to evaluate the climatic conditions tracked by the species in transitional months. Overall, models revealed significant geographic inter-prediction between seasons. Similarity analyses showed high niche overlap between seasons; however, they failed to reject the null hypothesis of niche similarity. As expected by the hypothesis of niche conservatism in the tropics, Yellow-green Vireo is a niche follower. This information will help to clarify evolution of intratropical migration and provide ecological information for future conservation plans.","PeriodicalId":49603,"journal":{"name":"Revista Mexicana de Biodiversidad","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135978875","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}

In the present paper, hypanthium trichomes of 24 species of Miconieae were investigated, 8 species of Miconia sensu stricto and 16 species of Leandra, as a contribution to the taxonomy of the tribe. Samples were obtained from herbarium and plant specimens collected in a state park in Paraná, Brazil. The hypanthium indumentum of the samples was analyzed using a scanning electron microscope. Our results revealed that long-peduncle stellate trichomes appear only within Miconias.s., while dendritic eglandular trichomes and glandular trichomes appear only in Leandra. Mixed trichomes with a lateral gland are less frequent and were found in both genera. It is not surprising, therefore, that the hypanthia of the investigated species possess indumentum of potential taxonomic significance. The characters of the indumentum of Miconia s.s., and Leandra may be useful in the infrageneric taxonomy of the new proposal for the tribe Miconieae.","PeriodicalId":49603,"journal":{"name":"Revista Mexicana de Biodiversidad","volume":"286 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135978877","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}
