Proyecto BioPaSOS: el uso de árboles en los ranchos como estrategia viable para la ganadería sustentable
(2020)
Este artículo aborda la importancia de la ganadería sustentable, donde la importancia de los árboles y arbustos beneficia de manera económica y ambiental. A su vez se muestra un ejemplo de ganadería en México en el que se ...
Water use, leaf cooling and carbon assimilation efficiency of heat resistant common beans evaluated in western Amazonia
(2021)
In our study, we analyzed 30years of climatological data revealing the bean production risks for Western Amazonia. Climatological profiling showed high daytime and nighttime temperatures combined with high relative humidity ...
Validating South Sudan as a Center of Origin for Coffea arabica: Implications for Conservation and Coffee Crop Improvement
(Frontiers in Sustainable Food Systems, 2021)
Cultivated Arabica coffee outside Ethiopia is plagued by low genetic diversity, compromising disease resistance, climate resiliency and sensory potential. Access to the wider genetic diversity of this species may circumvent ...
Agricultural Production of Central America and the Caribbean: Challenges and Opportunities
(2019)
En este artículo se abarca la agricultura en Centroamérica y el Caribe (CAC) que ha desempeñado un papel estratégico en el trabajo creación, ingreso rural, exportación promoción y seguridad alimentaria.
Higher leaf nitrogen content is linked to tighter stomatal regulation of transpiration and more efficient water use across dryland trees
(New Phytologist Foundation, 2022-05)
The least-cost economic theory of photosynthesis shows that water and nitrogen are mutually substitutable resources to achieve a given carbon gain. However, vegetation in the Sahel has to cope with the dual challenge imposed ...
How Close Are We to Self-Provisioning? A Look at the Livelihood Strategies of Rural Households in the Southern Andean Region of Colombia
(MDPI, 2022-02-22)
Analyze the impact of livelihood strategies on self-sufficiency conditions in 162 rural households in the department of Huila, Colombia. Discuss: A. food source; B. composition of home gardens; C. push and pull factors ...
How Ecological Characteristics of Seasonal Migratory Species Influence Conservation Threats and Policy Needs
(University of Chicago Press Journals, 2023-03-08)
This article argues that effectively protecting migratory behavior and migratory species throughout their annual or life cycle habitats requires conservation policies that simultaneously consider the ecological, socioeconomic, ...
Active in situ and passive airborne fluorescence measurements for water stress detection on a fescue field
(Photosynthesis Research, 2022)
LEDFLEX is a micro-lidar dedicated to the measurement of vegetation fluorescence. The light source consists of 4 blue Light-Emitting Diodes (LED) to illuminate part of the canopy in order to average the spatial variability ...
Active and passive chlorophyll fuorescence measurements at canopy level on potato crops. Evidence of similitude of diurnal cycles of apparent fuorescence yields
(Photosynthesis Research, 2022)
We performed active and passive measurements of diurnal cycles of chlorophyll fuorescence on potato crops at canopy level in outdoors conditions for 26 days. Active measurements of the stationary fuorescence yield (Fs) ...
Effects of agro-forestry systems on the physical and chemical characteristics of green coffee beans
(Frontiers, 2023-07-12)
A study at CATIE, Costa Rica, examined 20 agroforestry systems for coffee plantations, testing different management practices and shade types. Physical and chemical attributes of green coffee beans were analyzed. Full sun ...
