Refining the Global Estimate of Mangrove Carbon Burial Rates Using Sedimentary and Geomorphic SettingsBackgroundPrevious research has focused on calculating accurate estimates of global mangrove carbon stock, while lacking studies examining global patterns of organic carbon (OC) burial. Mangrove forests are naturally highly variable, existing in different sedimentary (i.e., terrigenous- or carbonate-dominant) and geomorphic (i.e., delta, estuary, lagoon, open coast) environments. In addition, different anthropogenic factors affect their structure. Therefore, it is necessary to examine how the spatial variability of mangrove sedimentary and geomorphic settings affects global OC burial estimates. Open access copy available |
The status of forest carbon markets in Latin AmericaBackground:Latin America (LATAM) hosts some of the world’s largest tropical forests, which provide significant carbon sequestration and a major share of global forest carbon credits. Despite these benefits, deforestation and forest degradation remain critical issues. Forest carbon markets, both compliance and voluntary, have emerged as key mechanisms to finance conservation, reduce emissions, and enhance climate resilience. Open access copy available |
Warming induces unexpectedly high soil respiration in a wet tropical forestBackgroundTropical forests play a key role in regulating the global carbon cycle, exchanging more carbon dioxide with the atmosphere than any other terrestrial biome. However, limited in situ experiments constrain understanding of their response to climate warming. Understanding these responses is crucial, as even small changes in soil respiration in tropical regions can substantially influence global carbon dynamics and climate feedbacks.

Putting seedlings on the map: Trade‐offs in demographic rates between ontogenetic size classes in five tropical forestsBACKGROUND:The study examines tropical forests in regions such as Panama, Puerto Rico, Malaysia, Taiwan, and Ecuador, which are characterized by their high biodiversity and significant environmental challenges like cyclonic storms. These forests are ideal for investigating demographic trade-offs due to their diverse coexisting tree species that align along growth, survival, and stature recruitment axes. The forests have experienced varying levels of disturbance from natural events, making them unique examples for studying tree species’ life-history strategies and the mechanisms that facilitate species coexistence.

Patterns and controls on island-wide aboveground biomass accumulation in second-growth forests of Puerto RicoBackgroundSecondary or second-growth forests after land abandonment are a valuable contribution to global carbon sinks. Approximately 70% of the world’s tropical forests are secondary growth, so understanding the carbon sequestration rates on a large scale is important. Sequestration rates are controlled by both abiotic and biotic factors in each region. Open access copy available |
Aboveground carbon responses to experimental and natural hurricane impacts in a subtropical wet forest in Puerto RicoBackgroundCarbon sequestration is a major climate mitigating process. Tropical forests in particular sequester high amounts of carbon, however disturbance events such as storms can alter the ability of forests to sequester more carbon. Hurricanes create forest gaps and increase ground debris which both provide resources that may promote plant recruitment and growth. Open access copy available |
Restoration of Degraded Tropical Forest LandscapesBACKGROUNDForest loss and degradation negatively affect rural communities whose livelihoods are dependent on forests for ecological goods and services. To address the challenge, three solutions have been proposed, expanding networks of protected areas, improving agricultural productivity on abandoned lands and reforestation. Of the three, new approaches to restoration have shown to have the potential to address forest degradation and rural poverty. Available with subscription or purchase |
Factors Affecting Mortality and Resistance to Damage Following Hurricanes in a Rehabilitated Subtropical Moist ForestBackgroundThis study was conducted in the Luquillo Experimental Forest (LEF), which was previously abandoned pastureland reforested through mixed planting and natural regeneration.

Shade-grown coffee in Puerto Rico: Opportunities to preserve biodiversity while reinvigorating a struggling agricultural commodityBackgroundCoffee has been a traditional crop in Puerto Rico since the mid-1700s. As the global market became more competitive in the 20th century, the Puerto Rican government provided subsidies and policies to protect the sector as well as promoted the transition to shade grown coffee for higher yields in the 1980s. The researchers surveyed 100 farms and 5 agronomists to determine attitudes about this transition. Open access copy available |
