Pattern avoidance in forests of binary shrubs [PDF]
We investigate pattern avoidance in permutations satisfying some additional restrictions. These are naturally considered in terms of avoiding patterns in linear extensions of certain forest-like partially ordered sets, which we call binary shrub forests.

Shrub and dwarf shrub communities of Sangilen Plateau [PDF]
The paper presents a detailed ecological and caenotic characteristic of dwarf shrub and shrub communities growing in the highmountain belt of the Sangilen Plateau. The communities investigated were referred to the class of Loiseleurio-Vaccinietea Eggler 1952.

Constraints on shrub cover and shrub–shrub competition in a U.S. southwest desert [PDF]
AbstractThe cover of woody perennial plants (trees and shrubs) in arid ecosystems is at least partially constrained by water availability. However, the extent to which maximum canopy cover is limited by rainfall and the degree to which soil water holding capacity and topography impacts maximum shrub cover are not well understood.

Immediate effects of microclimate modification enhance native shrub encroachment [PDF]
Shrubs have become more dense and expanded beyond their range all over the world for a variety of reasons including increased temperatures, overgrazing, and alteration of historical fire regime.

Shrubs indirectly increase desert seedbanks through facilitation of the plant community [PDF]
The mechanisms supporting positive ecological interactions are important. Foundation species can structure desert biodiversity by facilitating seedbanks of annual plants, but the direct and indirect mechanisms of shrub effects on seedbank have not been ...

A shrub bending model to calculate the albedo of shrub-tundra [PDF]
At high latitudes, the albedo and energy budget of shrub-tundra landscapes is determined by the relationship between the fractional snow cover and the fraction of vegetation protruding above the snowpack. The exposed vegetation fraction is affected by the bending and/or burial of shrubs in winter and their spring-up during melt.

Cyrtophora citricola (Araneae: Araneidae: Cyrtophorinae), a first record for Turkey [PDF]
We recorded the tent-web spider Cyrtophora citricola (Forsskål, 1775) (Araneidae: Cyrtophorinae) from Turkey for the first time at two sites. Body measurements and a brief description of the female are presented, as well as information on the sites ...

A Multi-Temporal Object-Based Image Analysis to Detect Long-Lived Shrub Cover Changes in Drylands [PDF]
Climate change and human actions condition the spatial distribution and structure of vegetation, especially in drylands. In this context, object-based image analysis (OBIA) has been used to monitor changes in vegetation, but only a few studies have ...

Shrub facilitation increases plant diversity along an arid scrubland-temperate rainforest boundary in South America [PDF]
Theoretical models predict nurse plant facilitation enhances species richness by ameliorating stressful environmental conditions and expanding distributional ranges of stress-intolerant species into harsh environments.

Copper Complexation by Dissolved Organic Matter in arid Soils: A Voltametric Study [PDF]
A voltammetric method was used to estimate the complexing capacity of water extracts from both desert soils sampled at the root zone of creosote and salt cedar plants, and in soils from interspace or background regions where no vegetative influence was ...
