Humanity is facing a rapid decline in global biodiversity, caused mainly by tropical deforestation through industrial and smallholder agriculture. However, smallholder agriculture landscapes host areas containing home ...
Shade tree traits and microclimate modifications: Implications for pathogen management in biodiverse coffee agroforests
(Wiley Biotropica, New Jersey (Estados Unidos), 2021-04)
Diversified coffee agroforests modify microclimate conditions in comparison with monocultures, impacting the success of significant plant pathogens, such as Hemileia vastatrix, which causes coffee leaf rust (CLR). However, ...
Soil-Co2 efflux in simple and diverse ecosystems on a volcanic soil in Costa Rica
(Instituto Interamericano de Cooperación para la Agricultura (IICA), 1985-01)
El flujo de CO2 de un suelo relativamente fértil fue medido en nueve ecosistemas. Los ecosistemas tenían de 0,8 a 10 años de edad e incluyeron un suelo libre de vegetación, monocultivos de melina (Gmelina arborea) y yuca ...
Electrophoretic patterns of some Meloidogyne spp. from Costa Rica
(Instituto Interamericano de Cooperación para la Agricultura (IICA), 1985-01)
Se comparó las características de diez poblaciones de Meloidogyne spp. de Costa Rica obtenidas mediante la técnica de electroforesis con gel de almidón. Se encontró que, con uas pocas excepciones, los patrones enzimáticos ...
Effects of acid and hot water pretreatments and seed burial on the germination of tropical moist forest seeds
(1986-10)
Para determinar si las cubiertas duras de algunas semillas del bosque tropical húmedo fueron un factor causante de las demoras largas en su germinación, se escogieron 39 especies de Panamá y Costa Rica y se suavizaron ...
Time-varying pricing may increase total electricity consumption: Evidence from Costa Rica
(Elsevier, 2020)
We study the implementation of a time-varying pricing (TVP) program by a major electricity utility in Costa Rica. Because of particular features of the data, we use recently developed understanding ofthe two-way fixed ...
