Short summary
We studied rates of litter decomposition in natural and disturbed vegetation on elevation gradients of Mount Kilimanjaro to disentangle effects of climate and disturbance. Decomposition was slower in disturbed than in natural forests, but we did not find a negative effect of disturbance for non-forest vegetation. Decomposition slowed down with increasing land-use intensity, but only in the warm wet season. Temperature and humidity were the most important drivers of decomposition in all analyses.

In our study, we included bioturbation into a soil erosion model and ran the model for several years under two conditions: with and without bioturbation. We validated the model using several sediment fences in the field. We estimated the modeled sediment redistribution and surface runoff and the impact of bioturbation on these along a climate gradient. Lastly, we identified environmental parameters determining the positive or negative impact of bioturbation on sediment redistribution.

Short summary
We investigate the effect of bioturbators on near-surface soil by measuring the physical properties clay, silt and sand and the chemical macronutrients C, N and P for soil samples taken from mounds created via bioturbation and soil samples from surrounding soil as controls in three different climatic regions (arid, semi-arid and Mediterranean) in coastal Chile. Our findings show that already minor input of especially C and N by bioturbators in arid climates can impact ecosystem functioning.

In our study, we developed, tested, and applied a cost-effective time-of-flight camera to autonomously monitor rainfall-driven and animal-driven sediment redistribution in areas affected by burrowing animals with high temporal (four times a day) and spatial (6 mm) resolution. We estimated the sediment redistribution rates on a burrow scale and then upscaled the redistribution rates to entire hillslopes. Our findings can be implemented into long-term soil erosion models.

In the absence of mosquitoes, diseases such as Malaria and Yellow fever will not exist. Although mosquito larvae have been identified to be a non-selective food to dragonfly larvae, it is unclear if the two naturally co-exist, hence reported as a non-viable strategy for controlling mosquito populations. However, a simple experiment in tropical Africa has shown a significant reduction in mosquitoes following colonization of mosquito larvae habitats by the dragonfly, Bradinopyga strachani.

Short summary
During early succession plant communities show a decrease in the initial species richness and a change in the phylogenetic structure from random or clustered to overdispersion. We tested this general model in two regional distinct sites. In one region we found the expected trajectory of species richness while phylogenetic structure did not follow the expected trend. In the other region species richness did not follow the expected trajectory and phylogenetic structure remained clustered.

Our work presents a novel set of analyses to understand the geographic distribution of the disease vector ticks Dermacentor marginatus and D. reticulatus and summarize model uncertainties for interpreting results and identifying appropriate public health actions. We estimate the current potential distribution of important disease vectors, D. marginatus and D. reticulatus, and more importantly the future potential distribution of the species in response to global climate change in coming decades.

Understanding the carbon cycle is critical for designing effective policies to mitigate climate change. Herein, I synthesized the state of knowledge of the carbon cycle in tropical upland ecosystems. From the 135 documents found in databases, estimations of carbon stocks comprised three-fourths of the total studies, while the remaining fraction focused on carbon fluxes. It is necessary to obtain information on the main carbon fluxes and integrate it into climate change mitigation plans.

Short summary
Short summary
Native invaders are species that become ``invasive'' in their own native range to the point of becoming a nuisance. This demographic disregulation presents management challenges, but we question the usefulness of this term on four grounds: it adds nothing to a well-known management problem, can bias the perception of management options, neglects different causes underlying the disregulation of native and non-indigenous species, and excludes species that can become antropogenically disregulated.

Short summary
Tropical forests are faced with a loss of forest cover with effects on ecosystem processes. We quantified decomposition within forest fragments and sites affected by increasing levels of agricultural land-use intensity. Mass loss increased with the area of forest fragments and decreased with land-use intensification. Fragmentation has negative effects on litter decomposition. However, the magnitude of this negative effect was not as large as expected.
