Soil bacterial depth distribution controlled by soil orders and soil forms

Australian terrestrial environments harbour extensive RNA virus diversity

“…Numerous novel RNA viruses have been identified in Australia’s unique ecosystems (Geoghegan et al ., 2021; Harvey et al ., 2018; Le Lay et al ., 2020; Mahar et al ., 2020; Mu et al ., 2018; Pyke et al ., 2021; Chang et al ., 2021; Van Brussel et al ., 2022; Wille et al ., 2018). While efforts have been made to characterise the overall microbial communities of Australian soils (Bowd et al ., 2022; Xue et al ., 2022; Pino et al ., 2023), little work has been done on the Australian soil virome. We generated meta-transcriptomic data on 26 libraries from 16 soil and sediment samples taken from eastern (NSW) and western (WA) Australia.…”

“…An estimated 10 10 microbes are present in one gram of soil, with species diversity up to the tens of thousands (Raynaud and Nunan, 2014). Microbial community compositions both affect and depend on factors such as the physicochemical properties of soil (Singh et al ., 2009; Dequiedt et al ., 2011), land use (Tian et al ., 2017), and depth (Xue et al ., 2022). The abundance and diversity of organisms in soil implies that there must also be abundant and diverse viruses infecting these hosts, which may play their own roles in soil cycles and maintenance.…”

Frugivore distributions are associated with plant dispersal syndrome diversity in the Caribbean archipelagos

“…The mechanisms that drive island biodiversity patterns is a question that has long intrigued natural history scientists (Chase et al, 2019; Kessler & Shnerb, 2015; Russell & Kueffer, 2019). While abiotic characteristics, such as climate, geology and topography, alongside the effects of island configuration and biogeography, have been considered strong drivers of archipelagoes biodiversity (Craine et al, 2013; Daly et al, 2012; Leão et al, 2020; MacArthur & Wilson, 1967; Vejre et al, 2003; Xue et al, 2020), the effect of biotic factors, particularly frugivorous seed dispersers, in structuring plant diversity has been neglected by the literature. Here, we provide the most comprehensive, regional overview on seed plant and frugivore characteristics and distributions in the Caribbean archipelagos.…”

“…Elevation is known to influence climatic and hydrologic conditions (Kenward et al, 2000) and have been highly correlated with plant species distributions (Oke & Thompson, 2015). Meanwhile, soil conditions influence plant development, acting as an important indicator of soil microbial diversity (Xue et al, 2020), nutrient availability (Vejre et al, 2003), and water retention (Leão et al, 2020). For elevation, we obtained 30m resolution data from the Advanced Land Observing Satellite (ALOS) World 3D (Takaku et al, 2014; Todono et al, 2014).…”
