Kin recognition is density-dependent and uncommon among temperate grassland plants

Kin recognition in plants?

Nitrogen acquisition by plants and microorganisms in a temperate grassland

Nitrogen (N) limitation is common in most terrestrial ecosystems, often leading to strong competition between microorganisms and plants. The mechanisms of niche differentiation to reduce this competition remain unclear. Short-term (15)N experiments with NH4(+), NO3(-), and glycine were conducted in July, August and September in a temperate grassland to evaluate the chemical, spatial and tempora...

Kin recognition in plants: a mysterious behaviour unsolved.

Chemical communication plays an integral part in the rhizosphere and in larger ecological processes. The idea of kin recognition and perception of kin-specific chemical signals have long been recognized in microbial and animal models. By contrast, general chemical communication between plants has been well established, especially with regard to the negative communication between plants of two d...

[CO2]- and density-dependent competition between grassland species

The predicted ongoing increase of atmospheric carbon dioxide levels is considered to be one of the main threats to biodiversity due to potential changes in biotic interactions. We tested whether effects of intraand interspecific planting density of the calcareous grassland perennials Bromus erectus and Carex flacca change in response to elevated [CO2] (600 ppm) by using factorial combinations o...
