(2018)The terciopelo (Bothrops asper), is one of the most important venomous snakes in Costa Rica and common on agriculture where insecticides are frequently used for pest control. To assess the exposure to organophosphates on ... -
Effect of foliar applications of phosphites on growth, nutritional status and defense responses in tomato plants
(2020)The use of phosphite (Phi)-containing products as foliar fertilizers is a common practice in food production systems, yet their actual contribution as a source of phosphorus (P) for plant nutrition has been object of debate. ... -
Effect of forest disturbance on myxomycete assemblages in the southwestern Peruvian Amazon
(2012-06-16)Although the effects of microenvironmental factors on distribution patterns in myxomycetes have been investigated, studies of the responses of this group of organisms to different regimes of forest disturbance are ... -
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 ... -
