Cambios sinecológicos en una pradera permanente bajo influencia de talajeo, fertilización, quema y competencia interespecífica
(Instituto Interamericano de Cooperación para la Agricultura (IICA), 1974-07)In a permanent pasture, on trumao soil (flat land) some practices of common use were evaluated during a five years period. The evaluation was made using the frequency and botanical composition criteria. The treatments ... -
Shrunk coexistence: cattle exclusion and nutrient addition intensify competition between native and exotic grasses with low phenological overlap
(Pedro Peres-Neto, 2025-06-08)Exotic plants are becoming increasingly common worldwide, often driven by ecological factors such as domestic livestock grazing and soil fertilization. In temperate grasslands, native C4 and exotic C3 grasses are generally ... -
Potencial pod production and pod yields of F3 Amazon cacao budded of grafted on shoots regenerated from coppiced Amelonado trees
(Instituto Interamericano de Cooperación para la Agricultura (IICA), 1974-07)Árboles viejos de cacao Amelonado fueron sometidos a corte de rebrote (coppicing) mensualmente durante un año y los chupones regenerados fueron tanto injertados con yema o con púa con vástagos Amazonas F3, o dejados crecer ... -
Assessing land use effects on ecohydrological partitioning in the critical zone through isotope-aided modelling
(Wiley, 2023-09-11)The study examines how different land uses impact ecohydrological processes in the critical zone, focusing on water partitioning between evaporation, transpiration, and groundwater recharge. Using stable water isotopes and ... -
Active and passive chlorophyll fluorescence measurements at canopy level on potato crops. Evidence of similitude of diurnal cycles of apparent fluorescence yields
(Springer Nature Link, 2022-12-17)We performed active and passive measurements of diurnal cycles of chlorophyll fluorescence on potato crops at canopy level in outdoors conditions for 26 days. Active measurements of the stationary fluorescence yield (Fs) ... -
Crecimiento de terneros utilizando cantidades limitadas de leche y formulaciones con niveles proteínicos diferentes
(Instituto Interamericano de Cooperación para la Agricultura (IICA), 1974-07)A total of thirty male Holstein calves that had received colostrum were fed with limited amounts of milk for a five-week period. From the third week on, part of the milk was replaced by a calf starter diluted in water, and ... -

A scenario modelling approach to assess management impacts on soil erosion in coffee systems in Central America
(Elsevier, 2023-05-05)Soil erosion is one of the major causes of soil degradation worldwide, because it causes the depletion of soil organic carbon, nutrients, and water holding capacity. In Central America, coffee production is vulnerable to ... -
A global meta-analysis of soil organic carbon in the Anthropocene
(Nature, 2023-06-05)The study is a global meta-analysis on soil organic carbon in the Anthropocene, based on more than 25,000 primary studies. It examines how land-use change, land management, and climate change affect soil organic carbon ...
