Habitat fragmentation reduces plant progeny quality: a global synthesis
(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 ...
Efectos de la Fragmentación de Bosques y la Fenología de Floración sobre el Éxito Reproductivo y los Patrones de Apareamiento de Pachira quinata, un Árbol de Bosque Tropical Seco
Effects of forest fragmentation and flowering phenology on the reproductive success and mating patterns of the tropical dry forest tree Pachira quinata
(2003)
Los resultados de varios estudios sugieren que la fragmentación de bosques afecta los patrones deapareamiento y de éxito reproductivo de especies de árboles tropicales al reducir la actividad de poliniza-dores, la deposición ...
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 ...
Effect of fragmentation on the Costa Rican dry forest avifauna
(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 ...
Population and genetic structure of two dioecious timber species Virola surinamensis and Virola koschnyi (Myristicaceae) in southwestern Costa Rica
(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 ...
Lack of early inbreeding depression and distribution of selfing rates in the neotropical emergent tree Ceiba pentandra: Assessment from several reproductive events
(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 negatively affects effective gene flow via pollen, and male and female fitness in the dioecious tree, Spondias purpurea (Anacardiaceae)
(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
(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 ...
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. ...
