Analyses of taxon-clusters in replicated networks to assess alternative microbiomes in corals

Coral reefs face unprecedented declines in diversity and cover, a development attributed largely to climate-change-induced bleaching and subsequent disease outbreaks. Coral-associated microbiomes may strongly influence the fitness of their hosts and alter heat tolerance and disease susceptibility of coral colonies. Here, we describe a new coral disease found in Micronesia …

Wetlands in Drylands: Hidden Hotspots of Carbon Sequestration and Storage?

Although the term ‘wetlands in drylands’ sounds like a contradiction, many drylands host a range of ephemeral wetlands. Pans, for example, are widespread features in many drylands, representing topographic depressions of varying size and shape that host ephemeral, sometimes saline, bodies of shallow water following infrequent precipitation or river flooding …

The Influence of Trees, Shrubs and Grasses on Micro-Climate, Soil Carbon, Nitrogen and CO2 Efflux: Potential Implications of Shrub Encroachment for Kalahari Rangelands

Shrub encroachment is a well-documented phenomenon affecting many of the world’s drylands. The alteration of vegetation structure and species composition can lead to changes in local microclimate and soil properties which in turn affect carbon cycling. The objectives of this paper were to quantify differences in air temperatures, soil carbon, …

Integrating microbiomics into peatland management and restoration

Peatlands are Important global carbon stores but are also sensitive climatically controlled ecosystems dependent on the maintenance of high water tables. Consequently they are under threat in warmer drier future climate conditions. The natural resilience of peatland systems and the potential to engineer resilience through peatland restoration are therefore important …

Microbial transport and soil integrity in drylands

Dryland soils are particularly vulnerable to erosion because of low plant cover and low organic matter which is linked with water availability and biological constraints. It is increasingly recognised that dryland soils can be managed to minimise erosion, which has benefits such as increasing soil fertility, carbon storage, and prevention …

Bacterial 16S diversity of basal ice, sediment, and the forefront of Svínafellsjökull glacier via isolation chips and classical culturing techniques

Sub-glacial microbes are receiving increased attention due to their central roles in storage and release of greenhouse gases, such as methane and CO2. Climate change driven warming and resulting glacier retreat exposes bedrock that can contribute to soil formation in which subglacial-released microorganisms may play a crucial role. Basal ice, …
