Spatial variations of leaf morphometry in mangroves in La Havana, Cuba

Introduction: Mangroves represent 11 % of the emerged land of Cuba. There is no previous research describing foliar characteristics, but these variables can be used as health indicators in forest ecosystems. Objective: In the current study we describe folial morphometry in four mangroves around Hava...

No existen estudios previos que describan sus características foliares, a pesar de que estas variables pueden constituir indicadores del estado de los ecosistemas boscosos. Objetivo: En el presente trabajo se describen las características morfométricas de las hojas en cuatro manglares periurbanos de la ciudad de La Habana: Bajos de Santa Ana, Cojímar, Rincón de Guanabo y la laguna El Cobre-Itabo. Métodos: Se emplearon 1 472 muestras de hojas de Rhizophora mangle, Avicennia germinans y Laguncularia racemosa, recolectadas entre abril y julio 2019, a las cuales se les extrajeron ocho variables: largo de la lámina, ancho máximo, área, perímetro, asimetría lateral, ángulos interiores anterior y posterior y un índice de forma. Resultados: Se detectaron diferencias geográficas en varias de las dimensiones de las hojas en R. mangle y A. geminans, pero L. racemosa mostró características altamente constantes entre localidades. Las diferencias se relacionaron con las características geográficas y ambientales de las localidades. Las dimensiones de las hojas fueron consistentes con estudios realizados en otros países. Conclusiones: Es necesario continuar evaluando de forma precisa estos indicadores foliares para sustentar su uso en futuros monitoreos o investigaciones, y para ello el empleo de fotografías digitales presenta numerosas ventajas, que fundamentan su uso.

Objective: In the current study we describe folial morphometry in four mangroves around Havana city: Bajos de Santa Ana, Cojímar, Rincón de Guanabo and El Cobre – Itabo lagoon. Methods: We collected 1 472 leaves´ samples of Rhizophora mangle, Avicennia germinans and Laguncularia racemosa, between April and July in 2019, to extract eight foliar variables: length, width, area, perimeter, lateral asymmetry, inner angles and shape index. Results: Geographic differences several variables of leaves in R. mangle and A. germinans were detected, but L. racemosa showed high similarity among localities. Differences can be explained by environmental differences in localities. Conclusions: There is a need for more extensive research on these kinds of foliar indicators to support it use in future monitoring or researches, and for that using digital pictures fotografías pose many advantages.
