Shaded-Coffee: A Nature-Based Strategy for Coffee Production Under Climate Change? A ReviewBackgroundCoffee agroforestry systems are a natural climate solution that are used to reduce the impact of coffee cultivation on ecosystem health. Coffee generates over $200 billion in income globally each year, so ensuring the efficiency and success of cultivation is crucial for human livelihood. Coffee agroforestry systems are often variable, and there lacks a compiled knowledge base about these systems and practices. Open access copy available |
Bird Assemblages in Coffee Agroforestry Systems and Other Human Modified Habitats in IndonesiaBackgroundDeforestation in tropical regions such as Indonesia is mainly driven by need for agricultural expansion. Agroforestry systems for a major agricultural crop, coffee, are becoming increasingly popular as the need for forest restoration is more apparent. Coffee agroforestry provides benefits to biodiversity, though specific impacts of coffee shade trees on bird populations outside of the Neotropics and Africa are understudied. Birds are a highly important taxa and serve many vital ecological roles. Open access copy available |
Spatial patterns and drivers of smallholder oil palm expansion within peat swamp forests of Riau, IndonesiaBackgroundTropical peat swamps are a major carbon sink, and therefore critical for meeting global climate goals. There is also rapid loss of these ecosystem types due to agriculture practices and drainage. Oil palm (Elaeis guineensis) is often planted in drained peat swamps for production. Policies in Indonesia drive smallholder oil palm farms into peatlands and prevent their access to industrial fields. Open access copy available |
Fire and tree species diversity in tropical peat swamp forestsBackgroundIndonesia houses a large quantity of peat swamps, an ecosystem type that contains diverse plant species, and provides a habitat for endangered animals. Peat swamps are degraded due to logging and agriculture expansion, specifically with the use of fire. Peat swamps are highly susceptible to fires due to peat flammability. Peat swamps also house a large quantity of carbon, so restoration is a high priority. Available with subscription or purchase |
Tropical Forest Landscape Restoration in Indonesia: A ReviewBackgroundIndonesia has an exceptionally high amount of biodiversity and endemic species. As the timber industry has grown, deforestation and degradation drive biodiversity loss, air pollution, deteriorating water quality, and greater emissions. Restoration projects and policies are in place to balance ecological health and human livelihood across landscapes like the ones in Indonesia. Restoration projects are particularly complex in Indonesia due to land tenure clarity issues, disorganized institution, and other social aspects. The authors review forested landscape restoration progress in Indonesia and examines inhibiting factors in institution and policy as well as indicators of restoration benefits.

Tropical fruit production depends on wild insect communities: bees and lychees in ThailandBackgroundMost of the agricultural crops around the world depend on wild animal/insect pollination. Insect pollination is the most common in tropical regions, and is something that tropical tree fruits such as the native Asian lychee (Litchi chinensis). The roles of wild insects on lychee production in northern Thailand has not yet been evaluated. Available with subscription or purchase |
Drought reduces the growth and health of tropical rainforest understory plantsBackgroundPlant responses to drought are important to understand for agricultural practices and environmental stress. Susceptibility to drought varies among and between plant species. Most field studies on plant responses to drought in tropical rainforests ignore understory plant species such as saplings and shrubs. These species are important to understand because they are often more vulnerable to environmental stressors, and they contribute greatly to forest biodiversity. Open access copy available |
Density-dependent reproductive success among sympatric dipterocarps during a major mast fruiting eventBackgroundMasting or mast fruiting is the annual synchronous production of many seeds by a plant species. Masting is an important reproductive strategy that depends on the intensity of flowering and fruiting, as well as the seeds’ ability to survive herbivory and competition with other seeds. Southeast Asia, many tree species (particularly Dipterocarps) are known to synchronize their masting events and therefore, community-wide seed density is an important factor predicting successful reproduction.

Effects of plant species richness on the structure of plant-bird interaction networks along a 3000-m elevational gradient in subtropical forestsBackgroundThe structure and diversity of ecological communities is shaped by symbiotic plant and animal relationships. Some birds feed on fleshy fruit producing plants to disperse seeds and facilitate plant reproduction. Bird seed-dispersal networks are plant-animal assemblages that change with environmental conditions. Species richness and species specialization interact with elevation to result in unique assemblages. In this study, the authors examine how plant and bird interactions change with plant species richness along a 3000-meter gradient in a subtropical forest in China.

Forest ecosystem services at landscape level – Why forest transition matters?BackgroundForest transition theory describes patterns of forest decline and recovery. This theory explains what services change as forested landscapes shift in the three stages of recovery. This model covers both forest-type gradients (diversity and usage) and landscape gradients (connectivity and coverage). It is not yet understood how these forest transition stages influence the quantity and quality of ecosystem services. Open access copy available |
