Lack of early inbreeding depression and distribution of selfing rates in the neotropical emergent tree Ceiba pentandra: Assessment from several reproductive events 

Lobo Segura, Jorge Arturo; Jiménez, Dennis; Solís Hernández, Wendy; Fuchs Castillo, Eric J. (2015)
Premise of the study: Selfing and mixed mating systems are prevalent in many flowering plants. Purging of genetic load can occur in these species, reducing negative effects of selfing. Long‐term studies of the temporal and ...

Habitat fragmentation reduces plant progeny quality: a global synthesis 

Aguilar, Ramiro; Cristóbal Pérez, Edson Jacob; Balvino Olvera, Francisco Javier; Aguilar Aguilar, María de Jesús; Aguirre Acosta, Natalia; Ashworth, Lorena; Lobo Segura, Jorge Arturo; Martén Rodríguez, Silvana; Fuchs Castillo, Eric J.; Sánchez Montoya, Gumersindo; Bernardello, Gabriel; Quesada Avendaño, Mauricio (2019-05-14)
Most of the world’s land surface is currently under human use and natural habitats remain as fragmented samples of the original landscapes. Measuring the quality of plant progeny sired in these pervasive environments ...

Genetic Diversity and Spatial Genetic Structure of an Epiphytic Bromeliad in Costa Rican Montane Secondary Forest Patches 

Cascante Marín, Alfredo; Oostermeijer, J. Gerard B.; Wolf, Jan H. D.; Fuchs Castillo, Eric J. (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 ...

Population and genetic structure of two dioecious timber species Virola surinamensis and Virola koschnyi (Myristicaceae) in southwestern Costa Rica 

Riba Hernández, José Pablo; Lobo Segura, Jorge Arturo; Fuchs Castillo, Eric J.; Moreira, Juan (2014)
Selective logging regulations generally fail to account for sex ratios, sex size distribution, spatial patterns and genetic structure in dioecious timber species. Furthermore, sympatric congeneric dioecious tropical species ...

Genetic diversity and reproductive biology of the dioecious and epiphytic bromeliad Aechmea mariae-reginae (Bromeliaceae) in Costa Rica: implications for its conservation 

Cascante Marín, Alfredo; Trejos Hernández, Christian; Madrigal Brenes, Ruth; Fuchs Castillo, Eric J. (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. ...

Effective gene flow patterns across a fragmented landscape in southern Costa Rica for Symphonia globulifera (Clusiaceae); a species with mobile seed and pollen dispersers Patrones efectivos de flujo de genes a través de un paisaje fragmentado en el sur de Costa Rica para una especie con dispersores móviles de polen y semillas; Symphonia globulifera (Clusiaceae)
Patrones efectivos de flujo de genes a traves de un paisaje fragmentado en el sur de Costa Rica para una especie con dispersores moviles de polen y semillas; Symphonia globulifera (Clusiaceae) 

Solís Hernández, Wendy; Fuchs Castillo, Eric J. (2019-04)
In tropical trees, forest fragmentation has been shown to affect mating and gene flow patterns. Mobile dispersal vectors should be less sensitive to fragmented landscapes and may ameliorate the genetic effects of forest ...

Habitat fragmentation negatively affects effective gene flow via pollen, and male and female fitness in the dioecious tree, Spondias purpurea (Anacardiaceae) 

Cristóbal Pérez, Edson Jacob; Fuchs Castillo, Eric J.; Martén Rodríguez, Silvana; Quesada Avendaño, Mauricio (2021-03-01)
Habitat fragmentation is recognized as one of main threats to global biodiversity. Habitat fragmentation negatively affects population size and mutualistic interactions that directly impact plant fitness and genetic ...

Molecular characterization and genetic diversity of Jatropha curcas L. in Costa Rica 

Vásquez Mayorga, Marcela; Fuchs Castillo, Eric J.; Hernández Jiménez, Eduardo José; Herrera Murillo, Franklin; Hernández López, Jesús; Moreira González, Ileana; Arnáez Serrano, Elizabeth; Barboza Vargas, Natalia María (2017-02-09)
We estimated the genetic diversity of 50 Jatropha curcas samples from the Costa Rican germplasm bank using 18 EST-SSR, one G-SSR and nrDNA-ITS markers. We also evaluated the phylogenetic relationships among samples using ...

Effect of fragmentation on the Costa Rican dry forest avifauna 

Barrantes Montero, Gilbert; Ocampo Vargas, Diego; Ramírez Fernández, José Daniel; Fuchs Castillo, Eric J. (2016)
Deforestation and changes in land use have reduced the tropical dry forest to isolated forest patches in northwestern Costa Rica. We examined the effect of patch area and length of the dry season on nestedness of the entire ...
