A Review of Breeding Systems in the Pineapple Family (Bromeliaceae, Poales)
Cascante Marín, Alfredo; Núñez Hidalgo, Stephanie María (2023-07-05)Breeding systems play an essential role in plant sexual reproduction and influence speciation and extinction processes. However, our understanding of the breeding systems for particular neotropical angiosperm families is ... -

Alta capacidad de autofecundación y baja visitación de polinizadores en la epífita polinizada por colibríes Pitcairnia heterophylla (Bromeliaceae) en un bosque montano en Costa Rica
Ríos Reyes, Luis Diego; Cascante Marín, Alfredo (2017)La subfamilia Pitcairnioideae es la segunda más diversa de las bromelias (Bromeliaceae), un grupo exclusivo de la región Neotropical. Las bromelias pitcairnioideas poseen rasgos florales que se asume promueven el exo-cruzamiento ... -
Association between rainfall seasonality and the flowering of epiphytic plants in a Neotropical montane forest
Cascante Marín, Alfredo; Trejos Hernández, Christian Fernando; Alvarado Barrantes, Ricardo (2017)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 ... -
Blooming plant species diversity patterns in two adjacent Costa Rican highland ecosystems
Cristóbal Pérez, Edson Jacob; Barrantes Montero, Gilbert; Cascante Marín, Alfredo; Madrigal Brenes, Ruth; Hanson Snortun, Paul; Fuchs Castillo, Eric J. (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
Rodríguez Correa, Hernando; Oyama, Ken; Quesada Avendaño, Mauricio; Fuchs Castillo, Eric J.; Quezada Aguilar, Maura Liseth; Ferrufino Acosta, Lilian; Valencia Ávalos, Susana; Cascante Marín, Alfredo; González Rodríguez, Antonio (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 ... -
Composición florística y estructura de un bosque húmedo premontano en el Valle Central de Costa Rica
Cascante Marín, Alfredo; Estrada Chavarría, Armando (2001)Se estudió la estructura y composición florística de un remanente de bosque húmedo premontano (BHP) en la Zona Protectora El Rodeo, Valle Central de Costa Rica. Se establecieron tres parcelas permanentes (1 ha. cada una) ... -
Dispersal limitation in epiphytic bromeliad communities in a Costa Rican fragmented montane landscape
Cascante Marín, Alfredo; von Meijenfeldt, N.; de Leeuw, Hanneke M. H.; Wolf, Jan H. D.; Oostermeijer, J. Gerard B.; Den Nijs, Joannes C. M. (2009)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 ... -
Distribución de las formas de vida en la flora costarricense
Nivia Ruiz, Angela; Cascante Marín, Alfredo (2008)La diversidad de plantas de un país o región se puede interpretar desde la perspectiva ecológica de las especies utilizando un sistema de clasificación por “formas de vida”. En este trabajo (1) se describe la diversidad ... -
Diversidad y vulnerabilidad de la flora orquideológica de un bosque montano nuboso del Valle Central de Costa Rica
Cascante Marín, Alfredo; Trejos Hernández, Christian (2019)Los Cerros de La Carpintera son una formación montañosa en el Valle Central de Costa Rica que alberga remanentes de bosque nuboso en sus partes altas y están rodeados por áreas urbanas y agrícolas. Con el interés de promover ... -
Efecto de la fragmentación del Bosque Seco sobre el éxito reproductivo de una especie de árbol maderable: Samanea saman (Mimosaceae)
Cascante Marín, Alfredo (1999) -
Efectos de la Fragmentación del Bosque Tropical Seco Sobre el Éxito Reproductivo y la Estructura Genética del Arbol Samanea saman
Cascante Marín, Alfredo; Quesada Avendaño, Mauricio; Lobo Segura, Jorge Arturo; Fuchs Castillo, Eric J. (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 ... -
Elevational and seasonal patterns of plant pollinator networks in two highland tropical ecosystems in Costa Rica
Cristóbal Pérez, Edson Jacob; Barrantes Montero, Gilbert; Cascante Marín, Alfredo; Hanson Snortun, Paul; Picado, Beatriz; Gamboa Barrantes, Nicole; Rojas Malavasi, Geovanna; Zumbado, Manuel A.; Madrigal Brenes, Ruth; Martén Rodríguez, Silvana; Quesada Avendaño, Mauricio; Fuchs Castillo, Eric J. (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 ... -
