Seed Production and 22 Years of Climatic Changes in an Everwet Neotropical Forest

BACKGROUND:

Yasuní National Park in western Amazonia hosts one of the world’s most biodiverse and everwet tropical forests, with minimal seasonal variation in rainfall and temperature. Its stable climate and relative insulation from large-scale disturbances such as ENSO make it an ideal site to investigate long-term ecological responses to climate change. The forest’s biological richness and global conservation importance underscore the need to understand how shifting climatic conditions influence seed production and, by extension, forest regeneration and community dynamics.

Improving Sustainable Tropical Forest Management with Voluntary Carbon Markets

Background

Tropical forests play a vital role in global carbon sequestration, absorbing around 1 petagram (Pg) of carbon annually—more than any other terrestrial ecosystem. However, deforestation and forest degradation weaken their ability to mitigate climate change. While reduced-impact logging and sustainable forest management (SFM) aim to minimize damage, many SFM plans overlook differences in tree growth rates, species characteristics, and local site conditions. As voluntary carbon markets grow, they create new opportunities to fund improved forest practices through “carbon-focused sustainable forest management” (SFM + C), which integrates carbon sequestration goals into existing frameworks.

Could Payments for Forest Carbon Contribute to Improved Tropical Forest Management?

Background

This study addresses the ongoing debate over whether carbon finance can incentivize better logging practices, especially in areas where unregulated logging causes severe environmental degradation. Under the Kyoto Protocol’s Clean Development Mechanism (CDM), industrialized countries finance carbon sequestration projects in developing nations to help meet their emissions reduction targets. However, this approach raises concerns that such mechanisms may let developed countries delay cutting their own fossil fuel emissions. The paper investigates whether forest carbon payments can support improved natural forest management (NFM) in tropical regions.

Carbon Prospecting in Tropical Forests for Climate Change Mitigation

Background

Nature-based climate solutions—such as forest protection and restoration—play an increasingly central role in global climate mitigation strategies. However, the supply of high-quality carbon credits from forest protection projects fails to keep pace with rising demand. A major barrier is the lack of reliable data to guide investment decisions, particularly in pinpointing areas where forest carbon protection delivers both environmental and financial returns. This study evaluates the global potential of tropical forest conservation to generate investible carbon credits and quantifies the return on investment under current and projected carbon market conditions.

Carbon Costs and Bushmeat Benefits of Hunting in Tropical Forests

Background

Overhunting 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+.

Wild Meat Consumption in Tropical Forests Spares a Significant Carbon Footprint from the Livestock Production Sector

Background

Tropical 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.

Not Seeing the Forest for the Trees: The Oversight of Defaunation in REDD+ and Global Forest Governance

Background

REDD+ (Reducing Emissions from Deforestation and Forest Degradation) aims to mitigate climate change by preserving forest carbon stocks. Although REDD+ focuses mainly on reducing deforestation, it largely ignores defaunation—the loss of forest wildlife caused by unsustainable hunting. Many tropical forests suffer from "empty forest syndrome," where hunting removes large frugivores and seed dispersers, disrupting seed dispersal and carbon sequestration. This study highlights how REDD+ policies overlook the ecological role of forest fauna and argues that neglecting defaunation threatens the long-term success of forest conservation.

Synergistic Effects of Seed Disperser and Predator Loss on Recruitment Success and Long-Term Consequences for Carbon Stocks in Tropical Rainforests

Background

Defaunation—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.
