The political ecology playbook for ecosystem restoration: Principles for effective, equitable, and transformative landscapesBackgroundGlobally, land degradation and forest loss continue despite an increasing number of projects working towards ecological restoration. The authors of this paper argue that one of the reasons that restoration projects have been unable to achieve their goals and ensure ecological resilience is that they ignore the underlying issues of political inequity and injustice that drive ecological degradation.

Payments for ecosystem services and the fatal attraction of win-win solutionsBackgroundPayments for ecosystem services (PES) programs involve valuing and paying stewards of ecosystems for the services that these ecosystems create incentives for conserving them. These programs are sometimes characterized as ‘win-win’ solutions, with the potential to contribute to both biodiversity conservation and poverty reduction. The authors of this paper review the literature on PES programs and highlight some challenges of implementing them. Open access copy available |
Cash for conservation: Do payments for ecosystem services work?BackgroundPayments for ecosystem services (PES) programs make payments to land owners for the ecosystem services such as clean water or carbon storage that their land provides to create incentives to protect the land. One of the objectives of these projects is to promote local economic development along with conservation outcomes. Researchers have sought to critically assess the assumptions behind these programs and their implementation. Open access copy available |

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 |
Linking disturbance history to current forest structure to assess the impact of disturbances in tropical dry forestsBackgroundTropical dry forests are given less attention in studies compared to tropical humid forests, but they still experience high levels of disturbance, both natural and human-made. These disturbances heavily alter the characteristics of valuable remaining forest structures. There are gaps in knowledge about how the timing and type of disturbance affects forest structure in seasonally dry tropical forests. Open access copy available |
Old timber plantations and secondary forests attain levels of plant diversity and structure similar to primary forests in the West African humid tropicsBackgroundThere is a high rate of biodiversity loss and deforestation in tropical ecosystems. In order to maintain global biodiversity, it is necessary to conserve plant diversity in alternative forest landscapes such as secondary forests and plantations. Comparing conservation values and tradeoffs of different forest landscapes is important for sustainable forest management and conservation practices. Open access copy available |
Removing climbers more than doubles tree growth and biomass in degraded tropical forestsBackgroundTree climbing plants such as lianas are known to inhibit forest recovery by outcompeting trees after disturbances. The removal of climbers is recognized as a viable forest restoration management practice, however no best practices are established yet due to lack of research repetition and synthesis.

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.

Forest structure predicts species richness and functional diversity in Amazonian mixed-species bird flocksBackgroundSecondary forests between forest fragments are valuable sources of biodiversity during the regeneration process. In the Brazilian Amazon, understory birds are often an indicator of forest regeneration and overall health. Functional diversity is an important component of ecosystem health and services, yet little is known about the role it plays in the return of mixed-species bird flocks. Open access copy available |
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 |
Why bees are critical for achieving sustainable developmentBackgroundBees are the most dominant group of pollinators and they may hold a key to achieving the United Nation’s Sustainable Development Goals (SDGs). They have a great potential for promoting agricultural success, providing people with crop pollination services. However bee populations are declining due to habitat loss, pesticide use, and climate change. Knowing the extent to which bees contribute to SDGs and identifying their critical roles within SDGs is important for conservation targeting. Open access copy available |
Edaphic factors and initial conditions influence successional trajectories of early regenerating tropical dry forestsBackgroundEdaphic factors include soil characteristics and topography of a landscape. These factors are thought to have strong impacts on forest communities and can predict the trajectory of forest regeneration. Differing soil conditions and slopes result in varying species assemblages, growth rates, and overall tree cover. 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 |
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 |
