Evaluating alder-endophyte (Alnus acuminata-Frankia-Mycorrhizae) interactionsBackgroundThe study examines the interactions between Alnus acuminata (a nitrogen-fixing tree), Frankia (a nitrogen-fixing actinomycete), and vesicular-arbuscular mycorrhizae (VAM), specifically Glomus intra-radices. These symbiotic relationships are significant in upland areas of Costa Rica, Colombia, and Venezuela, where A. acuminata grows alongside pastures. Frankia forms root nodules that fix atmospheric nitrogen, while VAM enhances phosphorus uptake, crucial for plant growth in nutrient-poor soils. The study aims to understand the effects of these interactions on nitrogen fixation and seedling development under varying phosphorus levels. Available with subscription or purchase |
Erythrina (Leguminosae: Papilionoideae): A Versatile Genus for Agroforestry Systems in the Tropics.BackgroundThe genus Erythrina (Leguminosae) plays a crucial role in tropical agroforestry systems. These trees are adaptable and widely distributed in tropical and subtropical regions, with over 100 species globally. Erythrina species are known for their rapid growth, nitrogen-fixing capability, and adaptability to various environments, including low-fertility soils. Historically, they have been integrated into agricultural systems as shade trees, live fences, and forage sources. The diverse ecological benefits of Erythrina highlight its importance in addressing food security, environmental conservation, and rural livelihoods in tropical regions. Open access copy available |

Understanding the importance of primary tropical forest protection as a mitigation strategyBackground:Primary tropical forests play a key role in the urgent task of mitigating climate change. Nevertheless, despite the recognition of forest-based mitigation strategies, the role of primary forest protection has not been explicitly considered in international policy negotiations. The authors aim to address this deficit by estimating primary tropical forest ecosystem carbon stocks and flows. Open access copy available |
Ecological filtering shapes the impacts of agricultural deforestation on biodiversityBackground:Deforestation for agriculture poses a significant threat to biodiversity. However, the severity of these impacts varies in agricultural landscapes. This study emphasizes the need to understand the factors underlying this variation to predict future biodiversity impacts of agricultural land use. While previous studies focused on landscape features and management regimes, this article introduces the concept of filtering, suggesting that natural and anthropogenic filtering may shape biodiversity responses at large geographical scales Available with subscription or purchase |
Global restoration opportunities in tropical rainforest landscapeBackground:The identification of restoration opportunities, focusing on areas with both high potential for socioenvironmental benefits and feasibility for restoration, emerges as a crucial tool in meeting the ambitious restoration commitments set for the near future. Recognizing these opportunities can be integrated with other decision-making factors to establish priorities for the implementation and financing of the global restoration agenda.

Forest Health and Global ChangeBackground:In addition to facing natural disruptions such as drought, windthrow, insect infestations, diseases, and fires, forests are increasingly grappling with intensified stressors of anthropogenic origin. These stressors arise directly through activities like logging and clearing or indirectly through climate change, air pollution, and invasive species. The pace of these human-induced disturbances surpasses the adaptability of evolutionary processes, thus shaping the future of global forests through intricate responses to multiple stressors spanning local to global scales.

Mapping carbon accumulation potential from global natural forest regrowthBackground:The authors note that previous studies have estimated the potential for carbon sequestration through afforestation and reforestation, but there has been less focus on the potential for natural forest regrowth. They also highlight the need for more accurate estimates of carbon accumulation rates in regrowing natural forests, as well as a better understanding of the factors that influence these rates.

Plant Respiration in a Warmer WorldBackground:It has been estimated that, globally, plants release 60 gigatons of CO2 during the respiration process. Many studies have shown that an increase in global temperature will increase leaves respiration rates, which in turn will decrease carbon uptake and increase atmospheric CO2 concentration (contributing even more to higher global temperature).

Restoration of plant-animal interactions in terrestrial ecosystemsBackgroundPlant-animal interactions are understudied within ecosystem restoration contexts. They are crucial to restoration success, with valuable processes like pollination, seed dispersal, and herbivory. The potential of animal reintroductions in restoration practices is understudied as well. Understanding these interactions is an important piece for future restoration efforts.
