Nutrient remobilization is a key process in nutrient conservation in plants and in nutrient
cycling in ecosystems. To predict the productivity of terrestrial ecosystems, we thus need to …

Stomata are central players in the hydrological and carbon cycles, regulating the uptake of
carbon dioxide (CO 2) for photosynthesis and transpirative loss of water (H 2 O) between …

ABSTRACT Limestone substrates cover 20–30% of the continents and are the habitat of
many calcareous fern species, which grow preferably or exclusively on this substrate. In this …

Plant uptake and biological cycling processes are commonly the largest flux of nutrients in
terrestrial ecosystems. Hydrologic and other losses are offset by inputs from atmospheric …

The distributions of plant species are affected by characteristics of their environment, most
importantly climate and soils. Ferns and lycophytes (hereafter pteridophytes) are no …

Plants that naturally accumulate aluminium (Al) may also inadvertently accumulate rare
earth elements (REEs) due to the similar chemical properties of Al and REE trivalent ions …

The evolutionary mechanisms underlying the biogeochemical niche conservatism in forests
remain incompletely understood. Here we aimed to determine how the strengths of …

Methods We sampled surface soils and leaves from herbs, ferns, deciduous woody species,
and evergreen woody species across four forest landscapes (montane, valley, karst, and …

Background and aims The drivers of variations in leaf nutrient concentrations in cave-
dwelling plants remain poorly understood. We aimed to explore the effects of light, soil …

We investigated the effects of historic soil chemistry changes associated with acid rain, ie,
reduced soil pH and a shift from nitrogen (N)-to phosphorus (P)-limitation, on the …
