El efecto de los disturbios humanos afecta diferencialmente a las especies con base en sus atributos morfo-funcionales para responder efectivamente a las presiones ambientales. En toda comunidad biologica se desarrollan especies que son muy abundantes y especies poco comunes o raras. Estas ultimas suelen considerarse mas vulnerables ante la transformacion de sus habitats debido a que generalmente tienen bajas densidades poblacionales, estan geograficamente restringidas y se encuentran en habitats especificos. Para probar esta nocion, se evaluo la respuesta funcional de especies arboreas raras y abundantes en los bosques de montana de la Altiplanicie Central, Montanas del Norte y Sierra Madre de Chiapas, Mexico. Se eligieron cinco rasgos funcionales que reflejan una asociacion con la captura de recursos, crecimiento y regeneracion de las especies (tamano del arbol, area foliar, tipo de diaspora, mecanismo de dispersion y afinidad sucesional). Un analisis de clasificacion basado en la similitud de rasgos funcionales y distribucion mostro que las especies consideradas raras se agrupan en tipos funcionales claramente discernibles de un grupo de especies comunes. El conjunto de especies registradas como raras corresponden a arboles de talla pequena y crecimiento lento, tolerantes a la sombra, producen frutos drupaceos con dispersion zoocora (aves y mamiferos pequenos) y tienen afinidad sucesional tardia. Lo anterior reconoce los riesgos de la transformacion de los bosques sobre estas especies poco comunes y aboga en favor de su conservacion.","PeriodicalId":30046,"journal":{"name":"Polibotanica","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46995700","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}

La ciudad de Mexico se promueve como una ciudad en transito a la sostenibilidad por lo que ha puesto en marcha distintos planes y acciones enfocados al cuidado ambiental, dentro de los que se encuentran las AVU. Debido a esto, el presente trabajo tuvo como objetivo principal comparar, usando sistemas de informacion geografica (SIG) y censos poblacionales de INEGI (Instituto Nacional de Estadistica y Geografia), la superficie de AVU existentes en dos alcaldias de la ciudad entre 1990 y 2015. La informacion de INEGI se utilizo para conocer la situacion social de cada alcaldia en las fechas de estudio. Los resultados muestran que, si bien, las brechas sociales han disminuido en este periodo, existen grandes diferencias en la superficie y calidad de AVU entre ambas alcaldias, por lo que el objetivo de ser una ciudad ambientalmente sustentable aun no se cumple en la CDMX.

Mexico City is promoted as a city in transit to sustainability, which is why it has launched various plans and actions focused on environmental care, including the AVU. Due to this, the main objective of this study was to compare, using geographic information systems (GIS) and population censuses of INEGI (National Institute of Statistics and Geography), the area of AVU existing in two city halls of the city between 1990 and 2015 The INEGI information was used to know the social situation of each mayor's office on the study dates. The results show that, although social gaps have decreased in this period, there are large differences in the surface and quality of AVU between both municipalities, so the goal of being an environmentally sustainable city is not yet met in the CDMX.","PeriodicalId":30046,"journal":{"name":"Polibotanica","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49401940","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}

Anthropological works, indicate that the Mayan groups located in the cultural region denominated Mayan Lowlands knew this orchid, naming it Sisbic.

The objective of this research was to collect the knowledge and current use of vanilla in 31localities of Yucatan and Quintana Roo belonging to the Maya Lowlands recognized in the extraction of chewing gum. A survey was applied to 130 midwives, 48% of them recognize vanilla with eleven vernacular names, among which the term Sisbic stands out and four main uses: medicinal, ritual, perfume and flavoring.

The goal of this study was to analyze the mangrove groups, including their structure and dominance pattern under the influence of eight environmental factors (salinity, flood level, pH, air temperature, soil temperature, relative humidity, and content of organic matter 0-30 cm, 0-60 cm). The characteristic physical features and caused by the impact were described for each group. Mangrove structure was evaluated considering a forest inventory conducted in 40 sampling units (300 m). Density of live and standing dead trees, stumps and seedlings was estimated for 1ha. The dominance for each species was determined using the relative Importance Value. The identification of groups was carried out with ordination and classification routines. The species with the highest Importance Values were Rhizophora mangle (29.68%) and Laguncularia racemosa (27.33%). Comparatively, the general structure of mangroves in Soconusco in terms of density (2 792 steams ha), basal area (36.5 mha) and height (15.5 m) is greater than in other areas of the Mexican Pacific coast. Classification of vegetation data, based on the Relative Importance Value Index, defined five mangrove groups. Outstanding is the presence of a community dominated by Pachira aquatica. The highest density of trees and stumps was recorded in Conocarpus erectus grouping, while the highest density of seedlings was in Avicennia germinans grouping. 86.3% of sampled trees present ≤ 17.7cm diameter at breast height. The variables that correlate significantly with the axis 2 of the ordination biplot were organic matter (30-60 cm), salinity and flood level. Canonical Discriminant Analysis corroborated the differences between mangrove groups, with the first two canonical axes explaining 89.05% of the variation in the data. The community composition varied associated with physical and environmental conditions, and were structurally defined by basal area, crown diameter, height and density, as well as by factors that can be associated with an anthropic impact such as stump and seedling densities. It is recommended to consider the characteristics of each mangrove group to plan their management.","PeriodicalId":30046,"journal":{"name":"Polibotanica","volume":"1 1","pages":"39-58"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67978841","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}
