Resprouting Ability

Abstract:Many plant species in tropical dry forests partly base their ability to persist after disturbance on resprouting. Yet little is known if this ability can be affected by the intensity and seasonality of disturbance and whether the amount of resources (starch, N, P) stored in the taproot may constrain this response. We investigated resprouting after experimental clipping or burning, applied before or after the dry season and repeatedly in Acacia pennatula individuals in wooded rangelands of North-West Nicaragua. Each treatment was applied to 12 trees and replicated in six plots. One year after the onset of the experiment, survival and biomass recovery were significantly lower in burned than in clipped individuals (78% ± 4% and 75.3 ± 8.0 g vs. 94% ± 2% and 79.1 ± 6.8 g; mean ± SE). Whatever the disturbance applied, trees disturbed after the dry season significantly showed the lowest survival, growth and concentration of N and P. These results suggest that resprouting in dry tropical species may be constrained by intense disturbances (e.g. burning) but especially if they occur towards the end of the dry season. This phenological constraint could be due to the reduced availability of N and P as this dry season progresses.

Se comunican cincuenta y cinco especies de briófitos (21 hepáticas, 34 musgos) de los bosques secos de bajura y húmedos de montaña en la Península de Santa Elena y las Islas Murciélago, Guanacaste, Costa Rica. Más del 50% de las especies recolectadas son de distribución neotropical, 16% son pantropicales y 12% anfiatlánticas (América-África). Nueve por ciento de las especies tiene una distribución limitada a áreas que potencialmente poseen bosque seco en México, Cuba y Costa Rica. Brachymenium spirifolium, Fissidens juruensis var. juruensis, F. radicans, F. yucatanensis, Gymnostomiella vernicosa y Rhodobryum grandifolium son nuevos registros de Costa Rica. Uleobryum peruvianum y Cephaloziella subtilis son nuevos registros de Centroamérica. La mayor diversidad de briófitos se encuentra por encima de 500 m de altitud, en el bosque húmedo de montaña de los Cerros Santa Elena, donde la mayor parte de las especies son cortícolas. En los bosques secos, suelo, troncos caídos y rocas son los hábitats briofíticos más importantes.

Se estudió el uso diurno por especies faunísticas p 1 3de un ojo de agua natural (QDl y otro artificial (AW ) a finales de la época seca de 1990 en el Area de Conservacion de Guanacaste, Costa Rica. En total 9 19 individuos (seis especies de mamíferos y una de ave cinegética) consumieron agua de QD y 7 13 individuos (cuatro especies de mamíferos) de AQ. Se estimó que en un dia, las especies de vida silvestre estudiados tomaron 29.7 1 y 27.3 1 de agua de QD y AW, respectivamente. El total de agua consumido o evaporado de cada ojo de agua durante 24-horas fue estimado en 44.6 1 en QD y 4 1 . 1 1 en AW, con base en: al agua bebida durante 12 h por las especies seleccionadas, b) agua bebida por todos los otros individuos durante 24 h (QD = 1 4.85 1, AW = 13.65 1) y c) evaporación diaria (QD = 0.04 1, AW = 0.0 1 1). Para abastecer AW durante una epoca seca de 120 días, la administración del parque debe proveer 4 932 1 de agua. Se discute las implicaciones de manejo en las regiones de bosque seco neotropical.

Figs are a remarkable food resource to frugivores, mainly in periods of general fruit scarcity. Ficus calyptroceras Miq. (Moraceae) is the only fig species in a type of dry forest in western Brazil. In this study I examined the fruiting pattern as well as fig consumption by birds in F. calyptroceras. Although rainfall was highly seasonal, fruiting was aseasonal, since the monthly proportion of fruiting trees ranged from 4% to 14% (N = 50 trees). I recorded 22 bird species feeding on figs. In the wet season 20 bird species ate figs, while in the dry season 13 did. Parrots were the most important consumers. This group removed 72% and 40% of the figs consumed in the wet and dry seasons, respectively. No bird species increases fig consumption from dry to wet season. However, a group of bird species assumed as seed dispersers largely increases fig consumption from wet to dry season, suggesting the importance of this resource in the period of fruit scarcity. The results of this study points out the remarkable role that F. calyptroceras plays to frugivorous birds, in such a dry forest, since its fruits were widely consumed and were available all year round.
