However, the structure of its wood and the variability of microscopic characteristics between its biotypes is unknown. For this reason, this study seeks to fill th is gap with an anatomical analysis of the wood in its three planes (transverse, tangentia l, a n d radial) according to IAWA regulations in five biotypes of T. cocoa (aromático, criollo, forastero, trinitario y CCN51) from the Piuntza and Guayzimi sectors of the province of Zamora Chinchipe.

With this, it was shown that all the individuals analyzed, despite being of the same species, had anatomical differences, which shows that the microscopic study of woo d is a very useful tool for the identification of biotypes within a species.Keywords:Wood anatomy, cacao, biotype, IAWA, agrobiodiversity","PeriodicalId":118195,"journal":{"name":"Revista Investigación Agraria.","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116602924","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}

This document gives us a vision of the state of soil loss due to water erosion, framed in a set of selected ecosystem service indicators (ES) that include supply and demand indicators that represent the three main supplier, regulatory and sociocultural categories. The choice of appropriate indicators and their calculation is presented using the example of class ES \"massive stabilization and control of erosion rates\" and \"control of soil erosion water\". Nearly natural ecosystems often resist erosion to a greater extent than areas in use, whose erosion rates depend on natural parameters and factors related to use. The main indicator captures the protective effect of ecosystems against soil loss, calculated from the difference in annual losses and the rate of hypothetical erosion without vegetation. The objective is to show the development of indicators with a focus on stakeholder participation and adopt regulatory processes that help counteract the effects of soil erosion.
