Stand dynamics in a logged and silviculturally treated Costa Rican rain forest, 1988-1996
(ELSEVIER, Ámsterdam (Países Bajos), 1999)
The lowland rain forests of Central America are poorly known from the standpoint of management for timber production. We studied the stand dynamics of a logged Costa Rican rain forest under three different regimes of ...
Above-ground biomass storage potential in primary rain forests managed for timber production in Costa Rica
(Elsevier, Ámsterdam (Países Bajos), 2021-07)
Tropical forests play a fundamental role in mitigating climate change through storage of carbon in above- and below- ground biomass. Their mitigation potential is, however, affected by significant greenhouse gas emissions ...
Shade tree Chloroleucon eurycyclum promotes coffee leaf rust by reducing uredospore wash-off by rain
(Elsevier, Ámsterdam (Países Bajos), 2020)
addition, may interact with environment. To better understand shade trees effects on coffee leaf rust (CLR), we
studied three disease stages separately: sporulation, uredospore wash-off by rain, and uredospore deposition ...
Identification and distribution of melon-infecting viruses and their vectors in two provinces of Costa Rica
(IICA, San José (Costa Rica), 1993-07)
El virus de la mancha anular de la papaya o "papaya ringspot virus" (PRSV), el virus del mosaico de la sandía II o "watermelon mosaic virus II" (WMV-II), el virus del mosaico del pepino o "cucumber mosaic virus" (CMV) y ...
Diversidade da comunidade de plantas invasoras em sistemas agroflorestais com café em Turrialba, Costa Rica
(CATIE, Turrialba (Costa Rica), 2008)
The objective of this work was to evaluate the floristic composition of spontaneous species in coffee (Coffea arabica L.) cultivated in full sun and in agroforestry systems, under organic and conventional management.Twenty ...
Effects of trees on infiltrability and preferential flow in two contrasting agroecosystems in Central America
(2014)
We tested the hypothesis that trees have measurable effects on infiltrability, macroporosity, and pref-erential flows in agrosilvopastoral systems. Managing agricultural systems for water conservation is acritical component ...
Available soil water in a Coffea arabica-Erythrina poeppigiana, C. arabica-Eucalyptus deglupta and C. arabica monoculture plantations
(1999)
Se evaluó el agua disponible en el suelo de 0-15, 15-30, 30-45 y 45-60 cm de profundidad, en parcelas de café sin sombra y con sombra de Eucalyptus deglupta o Erythrina poeppigiana, durante la estación seca en el Valle ...
