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.
Neither insects nor wind: ambophily in dioecious Chamaedorea palms (Arecaceae)
Pollination of Neotropical dioecious trees is commonly related to generalist insects. Similar data for non‐tree species with separated genders are inconclusive. Recent studies on pollination of dioecious Chamaedorea palms ...
Genetic Diversity and Spatial Genetic Structure of an Epiphytic Bromeliad in Costa Rican Montane Secondary Forest Patches
Information on genetic variation and its distribution in tropical plant populations relies mainly on studies of ground‐rooted species, while genetic information of epiphytic plants is still limited. Particularly, the effect ...
Complex phylogeographic patterns indicate Central American origin of two widespread Mesoamerican Quercus (Fagaceae) species
The northern Neotropical region is characterized by a heterogeneous geological and climatic history. Recent studies have shown contrasting patterns regarding the role of geographic elements as barriers that could have ...
Epiphytic bromeliad communities in secondary and mature forest in a tropical premontane area
We analyzed the differences in species richness, community composition, population structure and within-tree location of epiphytic bromeliads in contiguous secondary and mature forests in a premontane area in Costa Rica. ...
Establishment of Epiphytic Bromeliads in Successional Tropical Premontane Forests in Costa Rica
Plant community composition is the combined result of species‐specific competitive abilities and the availability of propagules. For epiphytic plants, current hypotheses consider that dispersal‐related factors are most ...
Reproductive Strategies and Colonizing Ability of Two Sympatric Epiphytic Bromeliads in a Tropical Premontane Area
Predispersal characteristics that affect the reproductive success in plants may influence their colonizing ability. We evaluated this hypothesis in two sympatric epiphytic bromeliads in Costa Rica, Guzmania monostachia and ...
La familia Bombacaceae (Malvales) en Costa Rica
General descriptions and taxonomic keys to the nine genera (Bernoullia, Ceiba, Huberodendron, Matisia, Ochroma, Pachira, Pseudobombax, Quararibea, and Spirotheca) and twenty-four species of Bombacaceae species known to ...
Las plantas vasculares de El Rodeo, Costa Rica
La documentación florística de El Rodeo se remonta a finales del siglo XIX y a la fecha se conocen 1 034 especies de plantas vasculares nativas o naturalizadas y 47 especies introducidas cultivadas (ornamentals o de interés ...
