Reflexiones sobre los sistemas silvopastorilesBackground:Los sistemas silvopastoriles (SSP) combinan árboles, pasturas, y ganado en un mismo espacio, promoviendo interacciones biológicas que maximizan el uso de la tierra. Representan una estrategia agroforestal para integrar la producción ganadera con la mitigación del cambio climático, al reducir gases de efecto invernadero y rehabilitar áreas degradadas por prácticas extensivas de baja productividad.

The soil organic carbon in particle-size separates under different regrowth forest stands of north eastern Costa RicaBACKGROUND:Costa Rica, having experienced significant deforestation from 1950 to 1984, now sees a rise in secondary forests due to land abandonment and reforestation efforts. These forests vary widely in soil carbon accumulation, influenced by the previous land use intensity and the age of the forest. The paper investigates the role of secondary forests in Costa Rica in soil organic carbon (SOC) sequestration, a critical component in understanding climate change mitigation potential.

The soil C pool in different agroecosystems derived from the dry tropical forest of Guanacaste, Costa RicaBACKGROUND:Seasonally dry tropical forests, constituting 42% of all tropical forests, are critically endangered, with less than 0.1% protected in Pacific Mesoamerica. The preservation of these forests is severely threatened by the invasive, highly flammable grass Hyparrhenia rufa, which has aggressively colonized the area since the 1940s. The paper focuses on examining soil carbon pools across various ecosystems derived from these forests in Guanacaste, Costa Rica, emphasizing the urgent need for comprehensive research on their soil carbon dynamics.

Restauración ecológica de bosques tropicales en Costa Rica: efecto de varios modelos en la producción, acumulación y descomposición de hojarascaBackground:La deforestación altera los ciclos de nutrientes y aumenta la fuga de nutrientes del ecosistema con altos costos ambientales y sociales. No obstante, la deforestación sigue siendo intensa en la mayoría de los países tropicales, especialmente en América Latina, donde los bosques son talados y rápidamente convertidos para la agricultura. Así, las estrategias de restauración en los trópicos son indispensables considerando la gran escala de degradación y la necesidad de mantener procesos ecológicos vitales.

Assisted restoration interventions drive functional recovery of tropical wet forest tree communitiesBackgroundIntegrating science and practice is one of the main goals of the U.N. Decade on Ecosystem Restoration. A variety of factors can influence the application of restoration treatments across tropical ecosystems. Deciding where to apply a restoration strategy on the spectrum between natural regeneration an active restoration planting can be challenging and there is not enough current knowledge that compares these methods.

Pollinator recognition by a keystone tropical plantBackgroundThe evolution of flowering plants is complex and has resulted in a great amount of diversity in species both genetically and structurally. Pollination is the key to providing this variability and is responsible for evolutionary patterns and trends in flowering plant species. Some flowering plants are generalists, allowing for many types of pollinators to visit, while others are highly specified. The mechanism for this specialization is not well understood.

How feasible are global forest restoration commitments?BACKGROUNDMany countries pledged large pieces of land for Forest Landscape Restoration to the Bonn challenge and the UNFCCC Paris Accords. The highest pledges came from the global South. Two countries have met their Bonn challenge so far. Some countries are facing challenges including deficit of the land committed, and there are competing land uses between FLR agricultural land. 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 |
Vulnerability of smallholder farmers to climate change in Central America and Mexico: current knowledge and research gapsBackgroundThis article recognizes that smallholder farmers are both critical to the global agricultural sector yet are one of the most vulnerable populations to climate change. Specifically, farmers in Central America and Mexico are experiences particularly high threats, thus the authors focus on this subgroup. Open access copy available |
The biogeochemical heterogeneity of tropical forestsBackgroundThis paper states that there has been a breadth of knowledge in relation to the biodiversity of tropical forests but limited about on the abiotic diversity, particularly biogeochemical effects. These later factors are becoming increasingly important to understand due to human perturbations in these forests. Open access copy available |
