Summary: Boreal peatlands play a crucial role in the carbon cycle by storing a significant amount of terrestrial carbon. However, warming temperatures can decrease soil moisture and consequently reduce the richness and abundance of soil microarthropods. Moisture content is an important driver of community composition in soil microarthropods.

Summary: Climate change-induced drying threatens northern peatlands and impacts photosynthesis. Little is known about the photosynthetic responses of existing and invading plant species to drier conditions. This study quantifies the long-term consequences of climate change-induced drying on peatland photosynthesis at the individual species and vegetation community levels. Results indicate that vascular plants are the main drivers of site-level productivity changes.

Summary: The research compared microbial communities in planted and unplanted wetland soil in Alaskan bog, finding that plant roots influence populations and metabolisms of methanogens and methanotrophs. Roots create an environment favoring specialized microbial metabolisms, with both aerobic and anaerobic metabolisms present as a result of the oxygen input.

Summary: The increase in species diversity towards the tropics is a remarkable global phenomenon that has not been fully explained yet. Evidence from ocean microfossils suggests that this pattern emerged due to ancient climate cooling and polar-climate dynamics.

Summary: This study used bi-temporal airborne lidar data to compare changes in vegetation height near anthropogenic disturbances in the Oil Sands Region of Alberta, Canada. The results showed that up to 50% of wetlands were disturbed by anthropogenic activities, with bogs experiencing increased shrub growth and expansion, while fens and swamps showed varying responses to disturbances. Wetland shapes becoming elongated were associated with a decline in shrub prevalence between the two time periods.

Summary: Extreme heat events, which are increasing in frequency and intensity, can have varying consequences on insect communities depending on their timing. This study found that the timing of heat waves had multiyear, timing-specific effects on plant-insect communities, with early-season heat waves having more significant and persistent effects than late-season heat waves. The study also showed that heat waves following experimental herbivory had reduced consequences. Overall, the results highlight the complex and lasting ecological effects of extreme climate events, emphasizing the importance of considering timing.

Summary: Climate change can alter interactions within a community by changing the relative phenology of interacting species, with some interactions being more vulnerable to temperature shifts than others. The geographic variation in the phenological response of species suggests a genetic component in determining local population phenology, adding complexity to understanding community responses to warmer temperatures.

Summary: The study shows that the conversion from black spruce to deciduous forest is already occurring on a regional scale in interior Alaska. The boreal deciduous forest type is likely to persist as a resilient alternate state through the 21st century, which will have important implications for regional climate and disturbance regimes.

Summary: This study examined the impact of climate change and land use patterns on the biomass patterns of Collembola, focusing on different life forms. The results showed that the response of Collembola biomass to these changes varied among different life forms. Specifically, surface-dwelling Collembola experienced a significant decrease in biomass, while soil-living Collembola were less affected. The reduction in Collembola biomass was mainly due to climate change-induced body size shrinkage and intensive land use-induced density reduction.

Summary: Soil food web models are powerful tools for calculating carbon and nitrogen mineralization, but current models have limitations in fixed parameters and generic trophic species. A new method with varying production efficiency and diet based on resource stoichiometry was proposed. Differences in C:N ratio can significantly impact estimates of carbon and nitrogen mineralization when trophic species are lumped together.

Summary: The Rhodniini tribe, originating around 17.91 million years ago, includes various species with distinct bioclimatic niches. The oldest species, Rhodnius domesticus, dates back to approximately 9.13 million years. Most species exhibit clear allopatric distribution and colonization of specific trees and bird nests plays a key role in the speciation of these taxa.

Summary: Climate warming can affect predator-prey interactions and predator feeding behavior by increasing metabolic demands. This study found that predators changed their prey selection under warming conditions, favoring small-bodied prey over larger-bodied prey, despite the potential for greater energetic gains from larger prey. These findings suggest that predators balance their increased metabolic demands by minimizing energy lost during feeding. The changes in predator feeding behavior with climate warming may have implications for food web dynamics and ecosystem-level processes.

Summary: Boreal peatlands are important for carbon storage, and soil fauna have a crucial role in regulating carbon and nitrogen fluxes. Climate change in northern latitudes will impact temperature and moisture conditions, affecting decomposition and ecosystem functioning. This research investigates the effects of simulated future climate extremes on peatland soil fauna and carbon and nitrogen fluxes. Results show that temperature and soil saturation affect faunal biomasses and drive changes in carbon flux and mineralization. The study highlights the need for further research on the potential impact of warming and hydrological changes on boreal peatland dynamics.

Summary: The study investigated the Collembola communities in three coastal habitats of the Fernando de Noronha Archipelago in Brazil. The results showed the presence of a single endemic species in sandy beach environments, while slope forest and top forest environments harbored generalist fauna with wide distribution on the mainland. Moisture content and litter layer depth were identified as the most important environmental factors influencing the communities. The findings suggest the need for dedicated nature conservation policies focusing on sandy beaches and slope forests.

Summary: This study examined the impact of restoration practices on earthworm and mesofauna communities in landfill sites. The results showed that the stockpiling, reapplication, and revegetation of native topsoil accelerated the natural re-colonization of earthworms. The study also found that highly disturbed sites had lower soil biological quality, while less disturbed sites had higher mesofauna abundance and richness.
