Abstract:
... Tedera, (Bituminaria bituminosa C.H. Stirt var. albomarginata) a herbaceous deep rooted perennial legume is being evaluated as a summer-autumn feed for sheep production in South Western Australia (SWA). As soils of SWA are generally infertile it was necessary to determine the requirement of phosphorous (P), potassium (K) and sulfur (S) for growth of tedera compared with subterranean clover. This w ...

Abstract:
... Most invasive plants have been originally introduced for horticultural purposes. Still, most alien garden plants have not naturalized yet, probably due in part to inadequate climatic conditions. Climate change may alter this, but few experimental studies have addressed this for non‐naturalized alien garden plants, and those that have, addressed only singular aspects of climate change. In a greenho ...

Abstract:
... Herein we describe a new fertilizer delivery system made of a thermoplastic starch composite used to control the release of nitrogen in greenhouse trials. The innovative approach in this work is to use a natural matrix to disperse the N source using one extrusion processing step that is easily scalable. The extrudate was formed into a continuous strand using a rod die and was subsequently air-cool ...

Abstract:
... It is frequently assumed that species capable of fast nitrogen (N) acquisition under different N‐availability conditions should have a higher establishment success after their introduction into new regions. However, few experimental studies have explicitly tested this. Our multispecies experiment tested whether global naturalization success of plant species native to Central Europe is related to a ...

Abstract:
... Drought affects not only nutrient cycling but also the internal cycling in the plant. We conducted a greenhouse experiment with lucerne at low, moderate and high soil water levels (LW, MW and HW). Green-leaf N:P (N:Pgᵣ) decreased at squaring and flowering stages as water supply increased, while senesced-leaf N:P (N:Pₛₑₙ) increased mostly. N:Pgᵣ increased with the growth at LW and MW, while hardly ...

Abstract:
... The enormous variation in seed mass along gradients of soil resources has fascinated plant ecologists for decades. However, so far, this research has focused on the description of such variation, rather than its underlying mechanisms. Here we experimentally test a recent model relating such variation to two fundamental properties of plant growth: allometry of biomass growth and size‐asymmetry of l ...

Abstract:
... Herbivory is one of the most important threats that plants face during early stages of development. Previous studies have indicated that seed size and seedling ontogeny strongly influence the response to herbivory at the seedling stage. However, little is known about their interactive effect. We simulated herbivory on seedlings of the exotic Gleditsia triacanthos L. and evaluated the combined effe ...
