| description | The floristic composition and species abundance of the seed bank and the rain of seeds are described and compared in eight seral communities (1-40 years old) related to milpa agriculture in a pine-oak forest area in the Highlands of Chiapas, Mexico. Sticky traps were used to evaluate the rain of seeds throughout their major production period (August 1988-April 1989). That abundance of buried seeds in the milpa field (112 seeds/m2) and in the old-field (92) was significantly lower than in the mid-successional forest (698) and grassland (578) stands. The floristic composition of the seed bank and that of the standing vegetation were not closely related. Pioneer species accounted for >85% of germinated seeds. Seed banks from the edge of different seral stands were richest in species (74 and 65), and included more exclusive species (9-12) than any of the surrounding communities (1-3). The seed rain showed a broad production and dispersal peak in October-February, and most of the trapped seeds were of pioneer species. An increasing forest fragmentation is occurring in the Highlands of Chiapas as a result of the current land use patterns. This deforestation, together with the biological attributes of pioneer species, allow for their accumulation in the soil of the remnant forested stands, and increase the invasion potential of a weedy and exotic flora. |

The floristic composition and species abundance of the seed bank and the rain of seeds are described and compared in eight seral communities (1-40 years old) related to milpa agriculture in a pine-oak forest area in the Highlands of Chiapas, Mexico.

Se describen y se comparan la composición florística y la abundancia de especies en el banco y en la lluvia de semillas en 8 comunidades sucesionales (1-40 años de desarrollo) derivadas de la agricultura de milpa en un área de bosque de pino-encino de Los Altos de Chiapas. Las menores densidades de semillas se encontraron en el campo de cultivo (112 ind/m2) y el campo recién abandonado (92) y las más altas en el bosque medianamente maduro (698) y el pastizal (589). En todas las muestras predominaron las semillas de especies pioneras (>85%) y no se encontró relación entre la composición florística del banco de semillas y la de la vegetación. Los bordes entre condiciones sucesionales tuvieron la mayor riqueza de especies (74 y 65) e incluyeron el mayor número de especies exclusivas (9-12). La lluvia de semillas fue mayor de octubre a febrero. Se encontró mayor número de semillas de especies anuales en el pastizal y el matorral que en las comunidades arboladas. Se propone que la fragmentación creciente de los bosques que ocasiona el patrón regional de uso actual del suelo, junto con los atributos biológicos de las semillas de especies pioneras, permite su acumulación en el suelo de las comunidades arboladas remanentes. Esto representa un incremento potencial de una flora invasora de arvenses nativas y exóticas conforme se extiende la desforestación para el uso agrícola del suelo.
