Information on mangrove stand development is rare because long-term monitoring data is often lacking. Such information is important in order to plan management measures effectively. Novel approaches based on existing datasets are required to bridge this gap of knowledge. This study uses a unique combination of field data analyses with simulation experiments in order to demonstrate how information on mangrove dynamics can be extracted if data are sparse. The paper provides a baseline characterization of stand development in a monospecific pioneer mangrove stand of Kandelia obovata. Point pattern analyses revealed that in the young stage, self-thinning has started but has not yet lead to a regularity of spatial tree distribution in the entire stand, and trees located in smaller clumps hinder each other in growth but do not lead to a significant size class differentiation. However, after ca. 2 decades the self-thinning and the size class differentiation start to become more visible. A mutual inhibition of growth was observed within 2 m circular distance (r) in the young stage and within 3 m distance after two decades of stand development as confirmed by the negative values of mark correlation function. As a stand grows older the spatial pattern of individuals become more regular from a clustered pattern. In order to understand and predict the future stand development, simulation experiments were carried out by means of the individual-based model KiWi

“…Others have suggested that the 'stranding' theory is more generally applicable, where larger propagules are stranded in deeper water and where only small propagules can successfully establish in shallow water i.e. high up in the intertidal zone (Rabinowitz, 1975;1978). Others argue that both strategies occur (Van Spreybroeck, 1992).…”

“…Entre los problemas más importantes a los que se han enfrentado los investigadores que se dedican al manejo y conservación del bosque de manglares y específicamente a la reforestación, es su reproducción por semilla (Vázquez, 1990). Se ha observado que la tasa de mortalidad de las semillas que produce el manglar es inversamente proporcional a su t amaño (Rabinowitz, 1978).…”

RESUMENCon el propósito de generar tecnología propia para el manejo agronómico en especies arbóreas de manglar, se inició un estudio que incluye la reproducción asexual de Laguncularia racemosa y Conocarpus erectus a través de acodos aéreos, usando como sustrato estopa de coco molida y aserrín, además de esquejes de dos edades ontogénicas (madera "blanda" y "semidura"). En el experimento se utilizó un diseño de bloques al azar. Entre los resultados destaca que el verano es la mejor época del año para la reproducción vegetativa y que el mejor medio reproductivo fueron los acodos aéreos con un 90% de enraizado. Los esquejes de madera "semidura" y de madera "blanda" de L. racemosa tuvieron un 50% y un 30% de éxito respectivamente, mientras que para Conocarpus erectus, tanto los esquejes jóvenes de madera "blanda" como los de madera "semidura", sólo lograron generar flujos vegetativos (retoños) aproximadamente a los tres meses de sembrados manteniéndolos de 6 a 12 meses, pero no presentaron raíces. PALABRAS CLAVE:Acodos aéreos, Conocarpus erectus, Laguncularia racemosa, esquejes, manglar, reproducción vegetativa. ABSTRACTThe obtention of new saplings through the induction of root formation in aerial shoots and conventional cuttings is a first, important step for agronomic management of mangrove forests. This possibility was studied with the species Laguncularia racemosa and Conocarpus erectus, with experiments carried out during four periods of the year, corresponding to the conventional four seasons of temperate climates. Root formation of aerial shoots on a substrate of ground coconut burlap and sawdust was 90% successful during summer (wet season). Conventional cuttings of young (soft) and older (semi-hard) wood were less successful. Only 50% and 30% of the semi-hard and soft cuttings of L. racemosa had rooted at the end of the trials. Those of C. erectus had few leaves and buds, which lasted between 6 and 12 months, but were unable to generate a functional root system.
