Ten principles for restoring campo rupestre, a threatened tropical, megadiverse, nutrient-impoverished montane grassland

Background

In the U.N. Decade on Ecosystem Restoration, one of the most overlooked ecosystem types is tropical grasslands. Studies on these ecosystems are lacking, as are the foundations for restoration. These foundational points of policy, practice, and governance in addition to science need to be addressed. The authors provide 10 principles to restore the campo rupestre, a tropical grassland that is threatened by human activities including mining.

Identifying hotspots for ecosystem restoration across heterogeneous tropical savannah-dominated regions

Background

In the U.N. Decade on Ecosystem Restoration, ecological restoration projects are a valuable tool for meeting global sustainability climate goals. Tropical regions are at the center of attention for their high biodiversity, carbon sink, and benefits to culture and human livelihood. Tropical dry savannahs are understudied even though they cover a large portion of tropical regions. Savannah dominated landscapes are valuable for their high plant diversity and vegetation type variation and high species turnover. Benefits to restoring these ecosystem types are also understudied.

Ecosystem restoration job creation potential in Brazil

Background

Ecosystem restoration is recognized globally for its environmental benefits. Other benefits from ecosystem restoration such as job creation may be of high interest to key stakeholders. The leverage of job creation may motivate additional investments and long-term commitment from stakeholders into restoration projects.

Goals and Methods

The authors aim to assess ecosystem restoration jobs in Brazil based on an online survey. Job structure, distribution, and abundance are measured. In total, the authors analyze results from 356 organizations’ responses covering almost the entirety of Brazilian estates.

The importance of insects on land and in water: a tropical view

Background

Insects 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.

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.

Frugivory and seed dispersal in the Cerrado: Network structure and defaunation effects

Background

Seed 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 Methods

The 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.

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.

Seed removal, seed dispersers, and the allocation of tissues in Myrtaceae seeds

Background

Plants 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.

Safeguarding sloths and anteaters in the future: Priority areas for conservation under climate change

Background

Sloths and anteaters come from the order Pilosa which has very little species richness and a high rate of species loss in recent years, making this order highly vulnerable to extinction. This order is distributed endemically in the Neotropics. Conservation concerns are high due to the high levels of habitat fragmentation and loss in Neotropical landscapes and conservation areas need to be prioritized to ensure Pilosa species survival.

Forest structure predicts species richness and functional diversity in Amazonian mixed-species bird flocks

Background

Secondary 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.
