Ecosystem Services of Mangroves: A Systematic Review and Synthesis of Contemporary Scientific LiteratureBackgroundMangroves provide many ecosystem services, such as breeding grounds for aquatic organisms, sediment accumulation sites, coastal protection, nutrient cycling, and carbon sequestration. Beyond ecological functions, mangroves also sustain coastal livelihoods by providing natural resources and contributing to local economies. However, anthropogenic pressures from coastal development, agriculture, and aquaculture degrade mangrove ecosystems and the important ecosystem services they provide. Therefore, it is important to quantify and describe mangrove ecosystem services to better inform coastal policymakers and managers interested in mangrove conservation. Open access copy available |

People and Mangroves: Biocultural Utilization of Mangrove Forest Ecosystem in Southeast AsiaBackgroundMangrove forests in Southeast Asia are recognized as biodiverse ecosystems that offer ecological, social, and economic benefits. However, this region also experiences the highest global rates of mangrove loss. This is concerning because the decline of mangrove forests in Southeast Asia potentially leads to the loss of valuable indigenous and local knowledge systems (ILKS) and even the disappearance of ethnic cultures.

Basin-Wide Effects of Game Harvest on Vertebrate Population Densities in Amazonian Forests: Implications for Animal-Mediated Seed DispersalBackgroundTropical forest ecosystems rely heavily on animal-plant interactions, especially seed dispersal by vertebrates. In the Amazon, widespread hunting significantly reduces populations of many vertebrate species, particularly large-bodied frugivores that play a key role in dispersing seeds of large-seeded plants. Although some species show greater sensitivity to hunting than others, the overall impact of hunting across the Amazon basin remains poorly quantified. This study aims to understand how subsistence hunting affects vertebrate populations and, in turn, the ecological services they provide—most notably seed dispersal. Open access copy available |
Carbon Costs and Bushmeat Benefits of Hunting in Tropical ForestsBackgroundOverhunting in tropical forests depletes frugivorous animals that play a vital role in seed dispersal. This loss alters tree species composition and reduces forest carbon storage. While bushmeat hunting remains an important source of protein and income for local communities, its long-term impact on carbon stocks remains poorly understood. This study investigates the trade-offs between the economic benefits of bushmeat hunting and the potential carbon costs of defaunation-driven biomass loss. Understanding these dynamics is essential for integrating hunting management into climate mitigation strategies such as REDD+. Open access copy available |
Wild Meat Consumption in Tropical Forests Spares a Significant Carbon Footprint from the Livestock Production SectorBackgroundTropical forest communities widely consume wild meat, which provides essential protein and micronutrients. While most discussions around hunting emphasize its ecological impacts—such as defaunation and biodiversity loss—this study shifts focus to its potential climate benefits. It investigates the greenhouse gas (GHG) emissions avoided when people consume wild meat instead of livestock products, especially bovine beef, a major driver of deforestation and emissions. By quantifying the carbon footprint of substitution, the study explores how sustainable hunting could contribute to climate change mitigation. Open access copy available |
Quantifying the Impacts of Defaunation on Natural Forest Regeneration in a Global Meta-AnalysisBackgroundIntact forests provide critical ecosystem services like carbon storage and climate regulation, relying heavily on interactions between woody vegetation and animal species. However, defaunation alters these interactions on a global scale. While previous studies explore defaunation’s effects on individual ecosystems, no comprehensive global analysis quantifies its impact on natural forest regeneration. This study conducts a meta-analysis to assess how vertebrate loss influences forest regeneration across multiple regions and ecosystems, identifying key taxonomic groups and ecological processes most affected by defaunation.

Synergistic Effects of Seed Disperser and Predator Loss on Recruitment Success and Long-Term Consequences for Carbon Stocks in Tropical RainforestsBackgroundDefaunation—the loss of animal species due to hunting, habitat destruction, and other human activities—affects tropical forests profoundly. Large frugivores play a key role in seed dispersal, while seed predators influence recruitment success and plant population dynamics. Previous studies focus mainly on how defaunation impacts seed dispersal but often overlook the role of seed predators and potential compensatory ecosystem effects. This study examines how losing both seed dispersers and seed predators simultaneously affects tree recruitment and long-term carbon storage in tropical forests. Open access copy available |
