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.

Latitudinal trends in plant-pollinator interactions: Are tropical plants more specialised?BackgroundTaxon diversity often correlates positively or negatively with latitude. Though much is known about species trends, species interaction trends have not been studied as much. Specifically, plant pollinator interactions in the tropics are a lesser known topic that must be explored. Goals and MethodsThe authors conduct a literature review searching for information on the latitude of study sites, pollinator species diversity and abundance, plant species, and interactions.

Cactus height increases the modularity of a plant–frugivore network in the Caatinga dry forestBackgroundSeed 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. Available with subscription or purchase |
Frugivory and seed dispersal in the Cerrado: Network structure and defaunation effectsBackgroundSeed dispersal is an important process for ecosystem functioning. The Brazilian Cerrado, the world’s largest and most biodiverse savanna, contains a plethora of animal dispersed plant woody plant species. The Cerrado region is understudied and identifying species roles in ecosystem networks needs to be better understood for evolutionary and conservation purposes. Goals and MethodsThe authors conduct a systematic literature review to form a seed dispersal network of the Cerrado. Plant-frugivore interactions, plant and animal species studies, and dispersal network papers are examined and included in a matrix for analysis. Open access copy available |
Human Persecution is An Important Threat to the Conservation of the Endangered Black-and-Chestnut Eagle in Northern AndesBackgroundHuman-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. Open access copy available |
Climate-Smart Conservation Agriculture, Farm Values and Tenure Security: Implications for Climate Change Adaptation and Mitigation in the Congo BasinBackgroundThe 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. Open access copy available |
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 |
