Fitocenosis en las pluvisilvas sobre ofiolitas del Parque Nacional Alejandro de Humboldt, Cuba Oriental

Abstract: Se estudiaron las condiciones fisionómicas, ecológicas y fitosociológicas de las fitocenosis observadas en los dos tipos de pluvisilvas sobre ofiolitas presentes en el Parque Nacional Alejandro de Humboldt; ellas son las más desarrolladas, extensas, conservadas y típicas del archipiélago cubano. Algunas tienen tres estratos arbóreos y alcanzan hasta 45 m de altura. Se presentan desde cerca del nivel del mar hasta los 900 m, con precipitaciones de alrededor de 2000 mm a 3600 mm. Se describen por primera vez dos… Show more

“…For studied vegetal formation denomination previously exposed criterion were followed [1,10]. The vegetation inventories (stands, samples, relevés) were done by using the Braun Blanquet`s [11] method, following the experience of various authors [6,7,12]. These inventories have a minimal area of 625 m 2 [13] and the abundance-dominance, sociability, vertical structure, layer and synucia description were stablished [6,14].…”

In addition oecotope observations were made in stands and its surroundings; in inventories place inclination of slope, exposition, altitude (masl), general relief and nano and micro relief were measure or estimated.…”

“…These species were collected in the Seasonal Semideciduous Forest (grid B4). Rubiaceae was also cited in studies carried out in North America (Cuba) due to its low frequency in epiphytic vascular flora surveys (Reyes and Cantillo, 2017). In Brazil, H. parasitica Jacq.…”

“…En nuestras condiciones de vegetación tropical y de acuerdo a los análisis realizados a múltiples ecosistemas cubanos [5,13], se modifican las anteriores propuestas de Loidi, considerándose parte de los "criterios fundamentales": naturalidad (N), resiliencia (R), valor florístico -fitocenótico (F) y unicidad fitocenótica o territorialidad fitogeográfica (UT), las que de conjunto constituyen el "valor biológico" (B). Las amenazas al ecosistema (A), son siempre negativas a las fitocenosis, reduciendo, afectando y/o minimizando a su vez la integridad de su "valor biológico" (B), por lo cual se restan del mismo.…”
