Extinction filters mediate the global effects of habitat fragmentation on animals
(Science, 2019)
Habitat loss is the primary driver of biodiversity decline worldwide, but the effects of fragmentation (the spatial
arrangement of remaining habitat) are debated. We tested the hypothesis that forest fragmentation ...
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 ...
The positive association between natural vegetation, native coccinellids and functional diversity of aphidophagous coccinellid communities in alfalfa
(2021-01)
1. A greater taxonomic and functional diversity of natural enemies in agroecosystems is frequently positively associated with more effective pest control, due to the complementarity of species or traits. But this diversity ...
Measured ammonia emissions from tropical and subtropical pastures: A comparison with 2006 IPCC, 2019 Refinement to the 2006 IPCC, and EMEP/EEA (European Monitoring and Evaluation Programme and European Environmental Agency) inventory estimates
(American Dairy Science Association, Champaign, IL, EUA ; Elsevier, Ámsterdam, Países Bajos, 2020)
Agriculture is the largest source of ammonia (NH3) emissions. As NH3 is an indirect greenhouse gas, NH3 measurements are crucial to improving greenhouse gas emission inventory estimates. Moreover, NH3 emissions have wider ...
Good data are not enough: Understanding limited information use for climate risk and food security management in Guatemala.
(2020)
Climate extremes are one of the main drivers of acute food insecurity. In Guatemala, acute food insecurity reaches alarming levels when the usual dry period during the bimodal rainy seasons is extended or starts earlier ...
The effects of propagation environment and foliar area on the rooting physiology of Cordia alliodora (Ruiz & Pavon) Oken cuttings
(Springer, Berlín (Alemania), 1997)
Influence of topographic and edaphic factors on vulnerability to soil degradation due to cattle grazing in humid tropical mountains in northern Honduras
(2015-01-22)
Low altitude humid tropical mountains in Central America have experienced a process of livestock expansion during recent decades. However, the use of sloping areas for cattle grazingmay lead to significant soil degradation
and ...
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 ...
Experimental field exclosure of birds and bats in agricultural systems — Methodological insights, potential improvements, and cost-benefit trade-offs
(ELSEVIER, 2019)
Experimental exclosure of birds and bats constitutes a powerful tool to study the impacts of wildlife on pests and crop yields in agricultural systems. Though widely utilized, exclosure experiments are not standardized ...
Diverse farmer livelihoods increase resilience to climate variability in southern Colombia
(Elsevier, 2023)
Climate variability affects agricultural production systems and rural communities, generating risks to food security and increasing rural poverty. Therefore, improving the capacity of rural households to adapt to climate ...
