Efecto de la perturbación del bosque en la tasa de visitas de murciélagos polinizadores y sus consecuencias sobre el éxito reproductivo y sistema de apareamiento en árboles de la familia Bombacaceae.
(2007)
La fragmentación y la perturbación del bosque pueden tener efectos deletéreos sobre el éxito reproductivo y el sistema de apareamiento de los árboles tropicales, además de modificar el compartimiento de sus polinizadores. ...
Efectos de la Fragmentación del Bosque Tropical Seco Sobre el Éxito Reproductivo y la Estructura Genética del Arbol Samanea saman
Effects of Dry Tropical Forest Fragmentation on the Reproductive Success and Genetic Structure of the Tree Samanea saman
(2002)
Tropical trees are particularly vulnerable to forest fragmentation because of their low densities, self-incompatibilty system, and high rates of outbreeding. Forest fragmentation is likely to decrease gene flow, increase ...
Habitat fragmentation negatively affects effective gene flow via pollen, and male and female fitness in the dioecious tree, Spondias purpurea (Anacardiaceae)
(2021-03-01)
Habitat fragmentation is recognized as one of main threats to global biodiversity. Habitat fragmentation negatively affects population size and mutualistic interactions that directly impact plant fitness and genetic ...
Elevational and seasonal patterns of plant pollinator networks in two highland tropical ecosystems in Costa Rica
(2024-01-11)
Many plant species in high montane ecosystems rely on animal pollination for sexual repro- duction, however, our understanding of plant-pollinator interactions in tropical montane hab- itats is still limited. We compared ...
Effects of selective logging on the abundance, regeneration and short-term survival of Caryocar costaricense (Caryocaceae) and Peltogyne purpurea (Caesalpinaceae), two endemic timber species of southern Central America
(2007)
In this study, we determined the effects of selective logging on the abundance of the last remnant populations of two tropical timber species with a restricted distribution, Caryocar costaricense and Peltogyne purpurea. ...
Habitat fragmentation reduces plant progeny quality: a global synthesis
(2019-05-14)
Most of the world’s land surface is currently under human use and natural habitats remain as
fragmented samples of the original landscapes. Measuring the quality of plant progeny sired in
these pervasive environments ...
Efectos de la Fragmentación de Bosques y la Fenología de Floración sobre el Éxito Reproductivo y los Patrones de Apareamiento de Pachira quinata, un Árbol de Bosque Tropical Seco
Effects of forest fragmentation and flowering phenology on the reproductive success and mating patterns of the tropical dry forest tree Pachira quinata
(2003)
Los resultados de varios estudios sugieren que la fragmentación de bosques afecta los patrones deapareamiento y de éxito reproductivo de especies de árboles tropicales al reducir la actividad de poliniza-dores, la deposición ...
Factors affecting phenological patterns of bombacaceous trees in seasonal forests in Costa Rica and Mexico
(2003)
We compared phenological patterns of tree species of the family Bombacaceae in three seasonal forests in Mexico and Costa Rica whose dry seasons vary in duration and intensity. The objectives were to (1) determine intraspecific ...
Pollen load size, reproductive success and progeny kinship of natural pollinated flowers of the tropical dry forest tree, Pachira quinata (Bombacaceae)
(2001)
Several studies have demonstrated, using controlled pollinations, that the number and identity of pollen grains deposited onto a flower's stigma affect the reproductive success of plants. However, few studies have shown ...
