The importance of insects on land and in water: a tropical viewBackgroundInsects provide a wide variety of ecosystem services such as pollination, nutrient cycling, and seed dispersal. The UN Sustainable Development Goals are thought to be supported by the conservation of diverse insect communities. The roles of tropical insects in ecosystem services and their contributions are summarized in this literature review. The authors identify research trends, knowledge gaps, and potential avenues for future investigations. Open access copy available |
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 |
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 |
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 |
Forest structure predicts species richness and functional diversity in Amazonian mixed-species bird flocksBackgroundSecondary forests between forest fragments are valuable sources of biodiversity during the regeneration process. In the Brazilian Amazon, understory birds are often an indicator of forest regeneration and overall health. Functional diversity is an important component of ecosystem health and services, yet little is known about the role it plays in the return of mixed-species bird flocks. Open access copy available |
