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.

Water resources are fundamental for social, economic, and natural development of (semi-)arid regions. Precipitation decreases due to climate change obligates us to find new water resources. Fog harvesting emerges as a complementary one in regions where it is abundant but untapped. This research proposes a model to estimate fog harvesting potential in coastal (semi-)arid regions. This model could have broader applicability worldwide in regions where fog harvesting could be a viable water source.

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.

The world is facing a critical issue of biodiversity loss and ecosystem degradation, despite efforts to address it. While positive steps are being taken in the adoption of comprehensive conservation policies, more effective science-for-policy approaches are necessary to foster connectivity, engage communities, and promote transformative change. This study outlines how scientists can drive impactful change within and beyond their communities to contribute to meeting global biodiversity targets.

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.

Marine stratocumulus clouds of the eastern Pacific play an essential role in the Earth's climate. These clouds form the major source of water to parts of the extreme dry Atacama Desert at the northern coast of Chile. For the first time these clouds are observed over a whole year with three remote sensing instruments. It is shown how these clouds are influenced by the land–sea wind system and the distribution of ocean temperatures.

Animal burrowing is important because it impacts the physical and chemical evolution of Earth’s surface. However, most studies are species specific, and compilations of animal community effects are missing. We present an inventory of the currently known 390 burrowing species for all of Chile along its climate gradient. We observed increasing amounts of excavated material from an area with dry conditions along a gradient towards more humid conditions.

In this study, we collected water from an Alpine catchment in Switzerland and compared the genetic information of eukaryotic organisms conveyed by eDNA with the hydrologic information conveyed by naturally occurring hydrologic tracers. At the intersection of two disciplines, our study provides complementary knowledge gains and identifies the next steps to be addressed for using eDNA to achieve complementary insights into Alpine water sources.

We explored what genetic material collected from water (eDNA) tells us about the flow of mountain streams, which are particularly valuable for habitat and water resources, but highly variable. We saw that when flow increased, more diverse eDNA was transported, especially in the main channel and tributaries. Whereas in the springs, we saw more diverse eDNA when the electrical conductivity of the water increased, likely indicating more underground surface contact.

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.

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.

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.

During an investigation on the effects of bottom trawling, we found that otter boards which keep nets open bury surface sediment at a few centimeters of sediment depth. This is also done by animals living in the sediment (bioturbation), a process that is considered very important for sediment ecosystem integrity. We try to differentiate between the two and estimate that natural bioturbation is much more likely than otter board sediment reversal in our investigation area.

Processes involved in the formation of deep-sea carbonate rocks remain controversial. It is reported in present study that macrofaunal burrowing may trigger the dissolution of the original calcite above the saturation horizon and thus drive deep-sea carbonate lithification on mid-ocean ridges. The novel mechanism proposed here for nonburial carbonate lithification at the deep-sea seafloor sheds light on the potential interactions between deep-sea biota and sedimentary rocks.

Plateau pika is common on the Qinghai-Tibet Plateau (QTP). Since pika dig burrows and graze on grassland to compete with yaks and sheep, they are believed to be a pest. They have been killed by humans since the 1950s. However, there are no serious studies that quantitatively evaluate the grazing and excavating effects of pika on grassland. With the advancement of UAV technology, we did a pilot study to evaluate the grazing and burying effects of pika.

In our study we propose new interpretation of commonly found trace fossil of genus Trichichnus which can be regarded as a fossilised bacterial mat system produced by giant sulphur bacteria related to genus Thioploca. We suggest that the bioelectrical processes may occur during some stages of live and/or post-mortem history of Thioploca-housed bacterial consortium. This greatly improves our understaniding of initial colonization of the marine sea floor after improvements of oxygenation.

Short summary
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.
In our study, we included bioturbation into a soil erosion model and ran the model for several...
