Ten principles for restoring campo rupestre, a threatened tropical, megadiverse, nutrient-impoverished montane grasslandBackgroundIn 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. Available with subscription or purchase |
Listening for change: quantifying the impact of ecological restoration on soundscapes in a tropical dry forestBackgroundTropical forest host a large portion of global biodiversity and carbon reserves. Heavy loss of these landscapes calls for restoration projects to conserve biodiversity as well as other ecosystem services related to human livelihood. Tropical dry forests are understudied compared to tropical wet forests, though they contain similar quantities of biodiversity, carbon, and sources for livelihood. One threat to tropical forest restoration is species invasion, which is linked to reduced native vegetation and habitat. Open access copy available |
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 |
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 |
Spatial density patterns of herbivore response to seasonal dynamics in the tropical deciduous forest of central IndiaBackgroundStrong seasonality of dry tropical forests causes variations in vegetation and therefore food resources for animals. This study investigates the seasonal distribution patterns between summer and winter of four ungulate species (Rusa unicolor, Axis axis, Bocephalus tragocamelus, and Sus scrofa) in the Panna Tiger Reserve in India. Ungulates tend to gravitate towards areas that are cooler with more vegetation, and at higher elevations. Available with subscription or purchase |
Legacy effects of canopy gaps on liana abundance 25 years later in a seasonal tropical evergreen forest in northeastern ThailandBackgroundLianas or woody vine species are abundant in tropical forests. They depend on trees for stability to grow and climb to the canopy. While lianas depend on trees for growth, they also require canopy gaps at early growing stages to satisfy their high demand for sunlight. At times, lianas occupy new treefall gaps densely enough to prevent tree regeneration. Tree host ability may influence the abundance of lianas in Southeast Asian seasonally dry tropical forests.

Selecting tree species to restore forest under climate change conditions: Complementing species distribution models with field experimentationBackgroundClimate-based species distribution models are used as a strategy to decide on optimal tree species for forest restoration projects. The criteria in these models is based on species performance in local climates. The limitation of species distribution models is that they do not include recruitment. Including the species successful reproduction, recruitment and growth at an early stage is vital for successful reforestation efforts. In addition, the models are not calibrated to take into account future climatic conditions, making it difficult to plan long-term restoration projects. Available with subscription or purchase |
A cautionary note for forest landscape restoration in drylands: cattle production systems in northwest Madagascar’s dry forestsBACKGROUNDIt is evident that land tenure security is crucial for successful restoration. Unfortunately, in Madagascar, dry forests are considered unoccupied and unowned even when communities have long-established claims under customary tenure systems. The authors stated that collective tenure recognition efforts were underway in Madagascar, but limited knowledge of agropastoralist cattle production strategies impeded the efforts to develop tenure reforms. The authors examined how cattle raisers in the Boney Region in northwest Madagascar organize pastoral spaces and cattle production strategies in the area’s dry forest. Open access copy available |
