Aim Potassium (K) is the second most abundant nutrient in plant photosynthetic tissues after
nitrogen (N). Thousands of physiological and metabolic studies in recent decades have …

The impact on nitrogen (N) and phosphorus (P) cycles of human activity is a growing
concern and has several causes and consequences (MacDonald et al., 2011; Peñuelas et …

Potassium, mostly as a cation (K+), together with calcium (Ca2+) are the most abundant
inorganic chemicals in plant cellular media, but they are rarely discussed. K+ is not a …

A significant increase in reactive nitrogen (N) added to terrestrial ecosystems through
agricultural fertilization or atmospheric deposition is considered to be one of the most …

Every living creature on Earth is made of atoms of the various bioelements that are
harnessed in the construction of molecules, tissues, organisms, and communities, as we …

Soil phosphatase levels strongly control the biotic pathways of phosphorus (P), an essential
element for life, which is often limiting in terrestrial ecosystems. We investigated the …

It has been recognized for a long time that the overstorey composition of a forest partly
determines its biological and physical–chemical functioning. Here, we review evidence of …

Studies on ecological stoichiometry (ES) have increased rapidly in number in recent years.
Continuous exploration of classical concepts such as the growth-rate hypothesis (GRH),) …

Abstract Background In the Mediterranean climate, plants have evolved under conditions of
low soil-water and nutrient availabilities and have acquired a series of adaptive traits that, in …
