Vegetation structure determines the spatial variability of soil biodiversity across biomes

Scientific Reports, 2020
The factors controlling the spatial variability of soil biodiversity remain largely undetermined. We conducted a global field survey to evaluate how and why the within-site spatial variability of soil biodiversity (i.e. richness and community composition)

Patterns of variability in early life traits of a Mediterranean coastal fish [PDF]

, 2013
Spawning dates and pelagic larval duration (PLD) are early life traits (ELT) crucial for understanding life cycles, properly assessing patterns of connectivity and gathering indications about patchiness or homogeneity of larval pools.

Multiscale Soil Investigations: Physical Concepts And Mathematical Techniques [PDF]

, 2008
Soil variability has often been considered to be composed of “functional” (explained) variations plus random fl uctuations or noise. However, the distinction between these two components is scale dependent because increasing the scale of ...

Simplified methods for deformation analysis of tunnel structures considering spatial variability of soil properties

Yantu gongcheng xuebao, 2022
The spatial variability of soil properties is widely accepted, and the response of a geo-structure can be significantly affected by the spatial variability of the surrounding soil mass.

Spatial variability of precipitation regimes over Turkey [PDF]

, 2010
Turkish annual precipitation regimes are analysed to provide large-scale perspective and redefine precipitation regions. Monthly total precipitation data are employed for 107 stations (1963–2002).

Spatial and temporal variability of iodine in aerosol [PDF]

Journal of Geophysical Research: Atmospheres, 2020
AbstractIn this work, we describe the compilation and homogenization of an extensive data set of aerosol iodine field observations in the period between 1963 and 2018 and we discuss its spatial and temporal dependences by comparison with CAM‐Chem model simulations. A close to linear relationship between soluble and total iodine in aerosol is found (∼80%

Climatic and oceanic associations with daily rainfall extremes over southern Africa [PDF]

, 2006
Changes in climate variability and, in particular, changes in extreme climate events are likely to be of far more significance for environmentally vulnerable regions than changes in the mean state.
