Climate-Smart Conservation Agriculture, Farm Values and Tenure Security: Implications for Climate Change Adaptation and Mitigation in the Congo BasinBackgroundThe Congo Basin forest houses a high amount of biodiversity and is an important area to conserve in light of climate change. This region is also important for agriculture and local livelihoods, though current practices are degrading the forest. Certain policy issues surrounding land tenure and investments may be hindering climate smart agriculture. Open access copy available |
Lightly-harvested rustic cocoa is a valuable land cover for amphibian and reptile conservation in human-modified rainforest landscapesBackgroundTropical biodiversity is impacted by anthropogenic land covers such as agriculture. Land use has the ability to both negatively and positively impact tropical biodiversity. In the tropics, important crops are grown in tropical forested landscapes such as coffee and cocoa. These forest understories are also important habitats for highly sensitive and ecologically vulnerable amphibian species. Amphibians and reptiles are an understudied taxa in conservation ecology and targeted in this study. Open access copy available |
National parks and conservation concessions: a comparison between mammal populations in two types of tropical protected areas in Ucayali, PeruBackgroundPeru holds the second largest portion of the Amazon rainforest and is threatened by illegal logging and crop cultivation, as well as mining and other activities. Protected areas are one method of forest conservation, which can exist as conservation concessions. These areas of land granted for protection and rehabilitation area vital to maintaining the health and distribution of the forest. Biodiversity is understudied in many of these regions, especially about terrestrial mammals. Open access copy available |
Tree Canopy Management Affects Dynamics of Herbaceous Vegetation and Soil Moisture in Silvopasture Systems Using Arboreal LegumesBackgroundIt is important to understand how herbaceous and arboreal species interact with each other, specifically how shade effects understory plants. Silvopasture functions best when both strata of the forest are thriving. Silvopasture is impacted by species chosen, spacing of tree plantings, and other management practices. Tree legume species such as Gliricidia sepium and Mimosa caesalpiniifolia hold a potential value for commercial use while also fixing soil nitrogen in the soil. Open access copy available |
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 |
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.

Tropical surface gold mining: A review of ecological impacts and restoration strategiesBACKGROUNDOpen access copy available |
Filling a void: Analysis of early tropical soil and vegetative recovery under leguminous, post-coal mine reforestation plantations in East Kalimantan, IndonesiaBACKGROUNDSurface mining is a common practice for obtaining coal, the world’s leading energy source. Surface mining removes vegetation, soil, and rocks to extract resources. In Indonesia, the world’s fifth largest coal producer, coal mining companies are required to rehabilitate mined sites. Companies typically plant exotic legume tree species because they quickly achieve canopy closure, limit invasive weeds, improve soil nitrogen, and create a light environment that helps with the recruitment of woody plants. This article looks to see whether natural forest succession occurs under leguminous plantations at rehabilitated coal mines in East Kalimantan, Indonesia. Available with subscription or purchase |
Adopt a carbon tax to protect tropical forestsBackgroundInternational investments in natural climate solutions such as conservation, restoration and land management remain low in many tropical countries. The authors point to research which shows that only 3% of global finance for climate change mitigation went towards natural climate solutions in 2017-18. They recommend constituting a national level carbon tax on fossil fuel companies to generate revenue to fund natural climate solutions. Open access copy available |
Carbon-focused conservation may fail to protect the most biodiverse tropical forestsIntroductionThe authors examine the relationship between carbon and biodiversity at the landscape-level across four gradients of disturbances and offer insight on optimizing carbon conservation projects with biodiversity conservation.
