Bee diversity in secondary forests and coffee plantations in a transition between foothills and highlands in the Guatemalan Pacific Coast.

PeerJ 2020 4;8:e9257. Epub 2020 Jun 4.

Instituto de Investigaciones en Ecosistemas y Sustentabilidad, Universidad Nacional Autónoma de México, Morelia, Michoacán, Mexico.

Background: Although conservation of pristine habitats is recognized in many countries as crucial for maintaining pollinator diversity, the contribution of secondary forest conservation is poorly recognized in the Latin American context, such as in Guatemala. San Lucas Tolimán (SLT) is a high-quality coffee production region from the Atitlan Province, which has the second highest deciduous forest cover in Guatemala and pristine forest is prioritized for conservation. In contrast, secondary forest protection is undetermined, since these forests are normally removed or strongly affected by coffee farming practices. Read More

Not so robust: Robusta coffee production is highly sensitive to temperature.

Glob Chang Biol 2020 06 17;26(6):3677-3688. Epub 2020 Apr 17.

Sustainable Management Services, ECOM Agroindustrial, Ho Chi Minh City, Vietnam.

Coffea canephora (robusta coffee) is the most heat-tolerant and 'robust' coffee species and therefore considered more resistant to climate change than other types of coffee production. However, the optimum production range of robusta has never been quantified, with current estimates of its optimal mean annual temperature range (22-30°C) based solely on the climatic conditions of its native range in the Congo basin, Central Africa. Using 10 years of yield observations from 798 farms across South East Asia coupled with high-resolution precipitation and temperature data, we used hierarchical Bayesian modeling to quantify robusta's optimal temperature range for production.

Negative plant-soil feedbacks are stronger in agricultural habitats than in forest fragments in the tropical Andes.

Ecology 2019 12 20;100(12):e02850. Epub 2019 Aug 20.

Smithsonian Tropical Research Institute, Balboa, Panama.

There is now strong evidence suggesting that interactions between plants and their species-specific antagonistic microbes can maintain native plant community diversity. In contrast, the decay in diversity in plant communities invaded by nonnative plant species might be caused by weakening negative feedback strengths, perhaps because of the increased relative importance of plant mutualists such as arbuscular mycorrhizal fungi (AMF). Although the vast majority of studies examining plant-soil feedbacks have been conducted in a single habitat type, there are fewer studies that have tested how the strength and direction of these feedbacks change across habitats with differing dominating plants.

Persistence of Coffea arabica and its relationship with the structure, species diversity and composition of a secondary forest in Brazil.

PLoS One 2018 14;13(3):e0194032. Epub 2018 Mar 14.

Institute of Biological Sciences, Federal University of Juiz de Fora, Juiz de Fora, Brazil.

Understanding the relationships between Coffea arabica L. and the native tree community of secondary forests regrowing after the abandonment of coffee plantations is important because, as a non-native species in the Neotropics, coffee can outcompete native species, reducing diversity and forests ecosystem services. We aimed to answer three questions: 1) Does coffee regeneration in secondary forests differ between shaded and unshaded abandoned plantations?; 2) How is coffee basal area related to structural attributes, species diversity and composition of the native community?; and 3) Do the relationships between coffee and native community differ between tree and sapling components? We sampled the tree and sapling components in a seasonal tropical dry forest that were previously used as shaded and unshaded coffee plantations. Read More

Floral resource availability from groundcover promotes bee abundance in coffee agroecosystems.

Ecol Appl 2017 09 10;27(6):1815-1826. Epub 2017 Jul 10.

School of Natural Resources and Environment, University of Michigan, 3541 Dana Building, 440 Church Street, Ann Arbor, Michigan, 48109, USA.

Patterns of bee abundance and diversity across different spatial scales have received thorough research consideration. However, the impact of short- and long-term temporal resource availability on biodiversity has been less explored. This is highly relevant in tropical agricultural systems for pollinators, as many foraging periods of pollinators extend beyond flowering of any single crop species. Read More

Does environmental certification in coffee promote "business as usual"? A case study from the Western Ghats, India.

Ambio 2016 Dec 21;45(8):946-955. Epub 2016 Jun 21.

Forest Management and Development (ForDev), CHN F 75.2, Universitaetstraase 16, 8092, Zurich, Switzerland.

Conservation initiatives are designed to address threats to forests and biodiversity, often through partnerships with natural-resource users who are incentivized to change their land-use and livelihood practices to avoid further biodiversity loss. In particular, direct incentives programmes that provide monetary benefits are commended for being effective in achieving conservation across short timescales. In biodiversity-rich areas, outside protected areas, such as coffee agroforestry systems, direct incentives, such as certification schemes, are used to motivate coffee producers to maintain native tree species, natural vegetation, restrict wildlife hunting, and conserve soil and water, in addition to encouraging welfare of workers.
