Molecular characterization and genetic diversity of Jatropha curcas L. in Costa Rica
(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 ...
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 ...
Genetic structure in neotropical birds with different tolerance to urbanization
(2022)
Gene flow in birds can be affected by urbanization depending on natural history traits and adaptability
to habitat change. Contrasting results can be expected when comparing species with opposite
resilience to urbanization. ...

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 ...
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 ...
Spatial Distribution of Whitefly Species (Hemiptera: Aleyrodidae) and Identification of Secondary Bacterial Endosymbionts in Tomato Fields in Costa Rica
(2020-10-19)
In Costa Rica, tomato (Solanum lycopersicum Linnaeus) Linnaeus (Solanales: Solanaceae) is one of the crops most severely affected by the whiteflies (Hemiptera: Aleyrodidae) Trialeurodes vaporariorum (Westwood) and the ...
Genetic structure in two avian species with different tolerance to urbanization: Case of white-eared ground-sparrow and house wren across an urban gradient
(2022)
El flujo génico en aves puede verse afectado por la urbanización dependiendo de la
historia natural y adaptabilidad de la especie al cambio de hábitat. Se pueden
esperar resultados contrastantes cuando se comparan ...
Genetic diversity in Oryza glumaepatula wild rice populations in Costa Rica and possible gene flow from O. sativa
(2016-04-07)
Wild crop relatives are an important source of genetic diversity for crop improvement. Diversity estimates are generally lacking for many wild crop relatives. The objective of the present study was to analyze how genetic ...
