Seasonal facilitative and competitive trade‐offs between shrub seedlings and coastal grasses [PDF]

, 2020
Shrub expansion is occurring in grasslands globally and may be impacted by the balance of competition and facilitation with existing grasses. Along the mid‐Atlantic and Gulf coasts, the native shrub Morella cerifera (wax myrtle) is rapidly expanding and ...

FO-Definability of Shrub-Depth [PDF]

, 2020
Shrub-depth is a graph invariant often considered as an extension of tree-depth to dense graphs. We show that the model-checking problem of monadic second-order logic on a class of graphs of bounded shrub-depth can be decided by AC^0-circuits after a ...

Effects of habitat and livestock on nest productivity of the Asian houbara Chlamydotis macqueenii in Bukhara Province, Uzbekistan [PDF]

, 2016
To inform population support measures for the unsustainably hunted Asian houbara Chlamydotis macqueenii (IUCN Vulnerable) we examined potential habitat and land-use effects on nest productivity in the Kyzylkum Desert, Uzbekistan.

Computing Shrub-Depth Decompositions [PDF]

, 2020
Shrub-depth is a width measure of graphs which, roughly speaking, corresponds to the smallest depth of a tree into which a graph can be encoded. It can be thought of as a low-depth variant of clique-width (or rank-width), similarly as treedepth is a low ...

The Influence of the Long-Term Outdoor Storage of Rockrose (Cistus laurifolius L.) Shrub Biomass on Biofuel’s Quality, Pre-Treatment and Combustion Processes

Biology, 2023
Biomass storage is an essential requirement in the supply chain of bio-refineries and power plants. This research aims to evaluate the influence of long-term outdoor storage (1 year) of baled rockrose (Cistus laurifolius L.) shrub biomass on biofuel’s ...

Shrub expansion in tundra ecosystems: dynamics, impacts and research priorities [PDF]

, 2011
Part of Focus on Dynamics of Arctic and Sub-Arctic Vegetation Recent research using repeat photography, long-term ecological monitoring and dendrochronology has documented shrub expansion in arctic, high-latitude and alpine tundra ecosystems. Here, we (1)

Effects of salinity, organic acids and alkalinity on the growth of calcite spherulites: Implications for evaporitic lacustrine sedimentation

The Depositional Record, 2022
Lacustrine non‐skeletal carbonates exhibit a diversity of petrographies due to interactions between physico‐chemical and biologically influenced mechanisms. Despite the suggestion that evaporative concentration was involved in the formation of spherulite

Differences in Soil Reinforcement and Root Fatigue Properties of Typical Shrubs in Semi-arid Mining Areas

Shuitu baochi tongbao, 2022
[Objective] The effects of cyclic load on root tensile resistance characteristics of three typical shrubs, and the change of soil reinforcement efficiency of shrub roots after fatigue were determined in order to provide a scientific basis for plant ...

Exploration of Thermal Bridging Through Shrub Branches in Alpine Snow

Geophysical Research Letters, 2023
In the high Arctic, thermal bridging through frozen shrub branches has been demonstrated to cool the ground by up to 4°C during cold spells, affecting snow metamorphism and soil carbon and nutrients.
