The adaptation of plants to particular soil types has long intrigued biologists. Gypsum soils
occupy large areas in many regions of the world and host a striking biological diversity, but …

Linear structural equation modeling has become an indispensable methodology for
specifying, estimating, and testing hypothesized interrelationships among a set of …

In semiarid environments, surface soil properties play a major role in ecosystem dynamics,
through their influence on processes such as runoff, infiltration, seed germination, and …

Semiarid Mediterranean regions are highly susceptible to desertification processes. This
study investigated the influence of increasing climate aridity in explaining the decline in …

Structural equation modelling (SEM) is a powerful tool to explore and contrast hypotheses
on causal relationships among variables using observational data. It constitutes an …

Plant–plant interactions are largely influenced by both environmental stress and ontogeny.
Despite the effects of each of these factors on the overall outcome of these interactions has …

Abstract Background and Aims Plants from gypsum habitats are classified as gypsophiles
and gypsovags. The former include both narrow endemics limited to small gypsum areas …

The four o'clock family (Nyctaginaceae) has a number of genera with unusual morphological
and ecological characters, several of which appear to have a “tendency” to evolve …

The southeast of the Iberian Peninsula, more precisely, the province of Almería, has the
most important gypsum quarries in Spain. Despite the severe environmental impact of these …

Despite advancements in our knowledge on the importance of biological soil crusts (BSC) in
arid and semiarid environments, little is known on the effects of specific crust organisms on …
