Genetic Diversity and Spatial Genetic Structure of an Epiphytic Bromeliad in Costa Rican Montane Secondary Forest Patches
(2014)
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 ...
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 ...
Genetic diversity and reproductive biology of the dioecious and epiphytic bromeliad Aechmea mariae-reginae (Bromeliaceae) in Costa Rica: implications for its conservation
(2019)
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. ...
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 ...
The effect of conspecific density, herbivory, and bamboo on seedling dynamics of a dominant oak in a Neotropical highland forest
(2019-10-17)
Conspecific negative density dependence (CNDD) is one of the main mechanisms
influencing diversity maintenance in tropical forests. Tropical highland forests, in
contrast to most lowland forests, are commonly dominated ...
Neither insects nor wind: ambophily in dioecious Chamaedorea palms (Arecaceae)
(2014)
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 ...
Blooming plant species diversity patterns in two adjacent Costa Rican highland ecosystems
(2023-01-12)
The Costa Rican Paramo is a unique ecosystem with high levels of endemism that is geographically isolated from the Andean Paramos. Paramo ecosystems occur above Montane Forests, below the permanent snow level, and their ...
Complex phylogeographic patterns indicate Central American origin of two widespread Mesoamerican Quercus (Fagaceae) species
(2017)
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 ...
Isolation and characterization of microsatellites for the neotropical dioecious palm Chamaedorea tepejilote (Arecaceae) and cross‑amplification in other Chamaedorea species
(2020-06-18)
Palms are important components of tropical and subtropical ecosystems and have even been considered keystone plant resources that can support a large array of pollinators and frugivores. Palms are also economically important. ...
