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 ...

Genetic And Morphological Variation Of The Sooty-capped Bush Tanager (Chlorospingus Pileatus), A Highland Endemic Species From Costa Rica And Western Panama
(2010)
We examined the effect of geographic isolation on morphology, genetic structure, and abundance of the Sooty-capped Bush Tanager (Chlorospingus pileatus), an endemic species restricted to highlands of Costa Rica and western ...
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 ...

Phenology of tree species of the Osa Peninsula and Golfo Dulce region, Costa Rica
(2007)
Se presentan datos sobre fenología de hojas, flores y frutos de 74 especies de árboles de la Península de Osa y Golfo Dulce, al Sureste de Costa Rica. Los datos fueron obtenidos de observaciones directas de árboles no ...
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 ...
Mating system and pollen flow between remnant populations of the endangered tropical tree, Guaiacum sanctum (Zygophyllaceae)
(2011)
Tropical trees are generally long-lived making it difficult to assess the long-term effects of habitat fragmentation on genetic diversity. Maintenance of genetic diversity in fragmented landscapes is largely dependent on ...
The International Oryza Map Alignment Project (IOMAP): the Americas—past achievements and future directions
(2022-12-17)
The wild relatives of rice hold unexplored genetic diversity that can be employed to feed an estimated population of 10 billion by 2050. The Oryza Map Alignment Project (OMAP) initiated in 2003 has provided comprehensive ...
Canines as a measuring tool for leaf tent construction in Dermanura watsoni
(2013)
Many animals are capable of constructing structures to modify the environment for their own benefit. The design of these structures requires animals to perceive dimensions. However, how animals take measurements to achieve ...
