Pollinator recognition by a keystone tropical plant

Background

The 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.

Cactus height increases the modularity of a plant–frugivore network in the Caatinga dry forest

Background

Seed dispersal plays an important role in maintaining ecosystem biodiversity. Disperser species with many plant interactions tend to be more abundant while species with fewer interaction tend to be rarer. Fruit accessibility is one plant factor that limits frugivore visits. Plant height is thought to affect fruit accessibility.

Human Persecution is An Important Threat to the Conservation of the Endangered Black-and-Chestnut Eagle in Northern Andes

Background

Human-wildlife conflicts are widespread and put threatened species at an even higher risk of extinction. Human persecution of threatened wild animals with the aim to protect domesticated animals contributes to the decline of threatened wild animals. The black-and-chestnut eagle is under threat in the northern Andes of Ecuador and Colombia due to efforts to protect domestic poultry.

Climate-Smart Conservation Agriculture, Farm Values and Tenure Security: Implications for Climate Change Adaptation and Mitigation in the Congo Basin

Background

The Congo Basin forest houses a high amount of biodiversity and is an important area to conserve in light of climate change. This region is also important for agriculture and local livelihoods, though current practices are degrading the forest. Certain policy issues surrounding land tenure and investments may be hindering climate smart agriculture.

Divergent litterfall nutrient responses to rainfall seasonality revealed through long-term observations in a tropical dry forest

Background

Forest 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.

The association between rainforest disturbance and recovery, tree community composition, and community traits in the Yangambi area in the Democratic Republic of the Congo

Background

Forests 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.

The Effects of Prescribed Dry Season Burning on Woody Species Composition, Mole National Park, Ghana

Background

Savannas 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.

Lightly-harvested rustic cocoa is a valuable land cover for amphibian and reptile conservation in human-modified rainforest landscapes

Background

Tropical 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.

National parks and conservation concessions: a comparison between mammal populations in two types of tropical protected areas in Ucayali, Peru

Background

Peru 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.

Tree Canopy Management Affects Dynamics of Herbaceous Vegetation and Soil Moisture in Silvopasture Systems Using Arboreal Legumes

Background

It 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.
