Pollination by nitidulid beetles in the hemi-epiphytic aroid Monstera lentii (Araceae: Monsteroideae)
Among aroids (Araceae family) with bisexual flowers, the reproductive biology of the neotropical genus Monstera (Subfamily Monsteroideae) is misunderstood. Nothing is known about the reproductive phenology and the sparse ...
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
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 ...
A New Quararibea (Malvaceae) from the Caribbean Lowlands of Costa Rica
We describe and illustrate a new species of Quararibea Aubl. from Costa Rica. Quararibea reflexipetalaCascante, J. Sánchez-Gonz. & W. S. Alverson is distinguished by its pleated petals with strongly reflexed and coiled ...
Evaluating factors that predict the structure of a commensalistic epiphyte–phorophyte network
A central issue in ecology is the understanding of the establishment of biotic interactions. We studied the factors that affect the assembly of the commensalistic interactions between vascular epiphytes and their host ...
Dispersal limitation in epiphytic bromeliad communities in a Costa Rican fragmented montane landscape
Transformation of tropical forests is likely to affect seed-dispersal patterns and influence the composition of epiphytic plant communities in human-altered habitats. We tested this hypothesis by carrying out a comparative ...
Matisia Tinamasiiana (BOMBACACEAE): una nueva especie arborescente del Pacífico Central de Costa Rica
El conocimiento de la Flora de Costa Rica ha sido, en gran parte, producto de la investigación y exploración botánica realizada principalmente dentro de las áreas protegidas estatales o privadas. Las áreas fuera de los ...
Additions to the Genus Bactris (Arecaceae)of Mesoamerica
Two new endemic species of Bactris, found in the understorey of humid forest on the Pacific Coast of Costa Rica, are described and illustrated. Bactris ana-juliae is 1.8-3.0 m tall, and B. herrerana is 2.0-3.0 m tall.
Association between rainfall seasonality and the flowering of epiphytic plants in a Neotropical montane forest
The association between the reproductive phenology of epiphytic communities with environmental and ecological factors remains largely unexplored. Because epiphytes depend on environmental moisture, seasonal changes in ...
A remarkable new species and additional novelties of Chamaedorea from Costa Rica and Panamá. Notables nuevas especies y novedades adicionales de Chamaedorea de Costa Rica y Panamá
Three of the four new spp. of Chamaedorea (Arecaceae) described here are endemic (as far as is known) to Costa Rica. The "remarkable" one is C. piscifolia Hodel, G. Herrera & Casc., with simple, apically bifid and long-caudate, ...
Genetic diversity and reproductive biology of the dioecious and epiphytic bromeliad Aechmea mariae-reginae (Bromeliaceae) in Costa Rica: implications for its conservation
Ecological traits and pollination mode associated with dioecious sexual expression in plants are likely to influence their reproductive success and levels of genetic diversity. Dioecy is an uncommon condition in Bromeliaceae. ...
