The generated model defined a good fit with the training data(presence records), since its AUC value was greater than 0.90, implying that the model is better than a random estimate. Thepotential distribution of this species is mainly influenced by altitude (ELEV), so it is found in areas close to coastal regions.Likewise, annual precipitation (BIO12) stood out in the definition of distribution, as did evapotranspiration (ETP) and averageannual temperature (BIO1). This was independent of the three arrangements of environmental variables that were tested. In general,this species of bamboo is in the Gulf of Mexico area and in a smaller portion in the Pacific region. It is noted that the results of thiswork should be interpreted as a good separation between the ideal areas and the inadequate areas for this species of Guadua nativeto Mexico.","PeriodicalId":447849,"journal":{"name":"e-CUCBA","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126605423","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}

First, it is proved that growth rings are reliable sources ofecological processes faced by trees. Their temporal dissection has refined the understanding of climate responses, as well as theirpotential to reconstruct carbon stocks at tree level. The integration of these natural records with remote sensing techniques haselucidated the seasonal modification of climate. Unmanned aerial vehicle (UAV) monitoring offers a spatial and spectralperspective usually ignored, but with great potential in forest monitoring. We document the benefits in estimating aerial attributesof the canopy, as well as indices on foliar dynamics and mention areas of opportunity.
