Ecosystem Services and Ecological Processes
Divergent litterfall nutrient responses to rainfall seasonality revealed through long-term observations in a tropical dry forestBackgroundForest litterfall can provide important nutrients to the soil for ecosystem health such as Phosphorus and Nitrogen. In water limited ecosystems rainfall often controls forest nutrient cycling. It is not yet understood how nutrient uptake of these nutrients is influenced by seasonal rainfall and how these litter nutrient contents change from year to year. Open access copy available |
The association between rainforest disturbance and recovery, tree community composition, and community traits in the Yangambi area in the Democratic Republic of the CongoBackgroundForests in the Congo Basin are becoming increasingly threatened by human disturbances. These forests play a crucial role in global biodiversity, though understanding the full impact of forest degradation has been difficult due to the intact canopy cover. It is important to assess the extent that human activities have impacted these forests to make decisions on the forests’ conservation and management practices. Open access copy available |
The Effects of Prescribed Dry Season Burning on Woody Species Composition, Mole National Park, GhanaBackgroundSavannas are valuable ecological communities that support many species and are known to be heavily shaped by fire disturbances. Fire is a recognized tool for controlling excess fuel and improving habitat. However, it is thought that the timing and frequency of fire prescriptions may impact characteristics of savanna growth and composition. Open access copy available |
Lightly-harvested rustic cocoa is a valuable land cover for amphibian and reptile conservation in human-modified rainforest landscapesBackgroundTropical biodiversity is impacted by anthropogenic land covers such as agriculture. Land use has the ability to both negatively and positively impact tropical biodiversity. In the tropics, important crops are grown in tropical forested landscapes such as coffee and cocoa. These forest understories are also important habitats for highly sensitive and ecologically vulnerable amphibian species. Amphibians and reptiles are an understudied taxa in conservation ecology and targeted in this study. Open access copy available |
National parks and conservation concessions: a comparison between mammal populations in two types of tropical protected areas in Ucayali, PeruBackgroundPeru holds the second largest portion of the Amazon rainforest and is threatened by illegal logging and crop cultivation, as well as mining and other activities. Protected areas are one method of forest conservation, which can exist as conservation concessions. These areas of land granted for protection and rehabilitation area vital to maintaining the health and distribution of the forest. Biodiversity is understudied in many of these regions, especially about terrestrial mammals. Open access copy available |
Tree Canopy Management Affects Dynamics of Herbaceous Vegetation and Soil Moisture in Silvopasture Systems Using Arboreal LegumesBackgroundIt is important to understand how herbaceous and arboreal species interact with each other, specifically how shade effects understory plants. Silvopasture functions best when both strata of the forest are thriving. Silvopasture is impacted by species chosen, spacing of tree plantings, and other management practices. Tree legume species such as Gliricidia sepium and Mimosa caesalpiniifolia hold a potential value for commercial use while also fixing soil nitrogen in the soil. Open access copy available |
Edaphic factors and initial conditions influence successional trajectories of early regenerating tropical dry forestsBackgroundEdaphic factors include soil characteristics and topography of a landscape. These factors are thought to have strong impacts on forest communities and can predict the trajectory of forest regeneration. Differing soil conditions and slopes result in varying species assemblages, growth rates, and overall tree cover. Open access copy available |
Why bees are critical for achieving sustainable developmentBackgroundBees are the most dominant group of pollinators and they may hold a key to achieving the United Nation’s Sustainable Development Goals (SDGs). They have a great potential for promoting agricultural success, providing people with crop pollination services. However bee populations are declining due to habitat loss, pesticide use, and climate change. Knowing the extent to which bees contribute to SDGs and identifying their critical roles within SDGs is important for conservation targeting. Open access copy available |
Drought reduces the growth and health of tropical rainforest understory plantsBackgroundPlant responses to drought are important to understand for agricultural practices and environmental stress. Susceptibility to drought varies among and between plant species. Most field studies on plant responses to drought in tropical rainforests ignore understory plant species such as saplings and shrubs. These species are important to understand because they are often more vulnerable to environmental stressors, and they contribute greatly to forest biodiversity. Open access copy available |
Seed removal, seed dispersers, and the allocation of tissues in Myrtaceae seedsBackgroundPlants allocate resources to protective seed tissues in order to avoid seed death and ensure successful reproduction. Myrtaceae is an abundant plant family in the Brazilian Atlantic forest with many species producing fleshy fruits that are attractive to birds, rodents, and other mammals. Myrtaceae species may adapt seed characteristics to avoid predation. Available with subscription or purchase |
