TL;DR: In this paper, an attempt to identify criteria with which to assess or anticipate the effect of competitive exclusion both at individual sites and in different types of vegetation is described, where the authors identify criteria for assessing or anticipating competitive exclusion.
Abstract: IN maintaining or reconstructing types of herbaceous vegetation in which the density of flowering plants exceeds 20 species/m2—the so-called “species-rich” communities, success is often frustrated by competitive exclusion. Here I describe an attempt to identify criteria with which to assess or anticipate the effect of competitive exclusion both at individual sites and in different types of vegetation.

TL;DR: It is hypothesized that the life form “tree” is limited at treeline altitudes by the potential investment, rather than production, of assimilates (growth as such,rather than photosynthesis or the carbon balance, being limited), and root zone temperature, though largely unknown, is likely to be most critical.
Abstract: In this review I first compile data for the worldwide position of climate-driven alpine treelines. Causes for treeline formation are then discussed with a global perspective. Available evidence suggests a combination of a general thermal boundary for tree growth, with regionally variable “modulatory” forces, including the presence of certain taxa. Much of the explanatory evidence found in the literature relates to these modulatory aspects at regional scales, whereas no good explanations emerged for the more fundamental global pattern related to temperature per se, on which this review is focused. I hypothesize that the life form “tree” is limited at treeline altitudes by the potential investment, rather than production, of assimilates (growth as such, rather than photosynthesis or the carbon balance, being limited). In shoots coupled to a cold atmosphere, meristem activity is suggested to be limited for much of the time, especially at night. By reducing soil heat flux during the growing season the forest canopy negatively affects root zone temperature. The lower threshold temperature for tissue growth and development appears to be higher than 3°C and lower than 10°C, possibly in the 5.5–7.5°C range, most commonly associated with seasonal means of air temperature at treeline positions. The physiological and developmental mechanisms responsible have yet to be analyzed. Root zone temperature, though largely unknown, is likely to be most critical.

TL;DR: The Biodiversity Exploratories (www.biodiversityexploratories.de ) as mentioned in this paper is a large-scale and long-term project for functional biodiversity, which includes a hierarchical set of standardized field plots in three different regions of Germany covering manifold management types and intensities in grasslands and forests.

...The natural vegetation cover of Germanymainly consisting of deciduous forests has been largely replaced by production forests, e.g. spruce plantations, and is now restricted to rather small and highly fragmented areas (Ellenberg 1996; MCPFE 2007)....

TL;DR: The regional variation in ancient forest plant species suggests that regional lists are more appropriate for assessing the nature conservation value of forests than one global European list and ancientforest plant species may be considered as important biodiversity indicators for forests.

TL;DR: In this article, the authors present a historical perspective on the development of conflicts related to biodiversity in agricultural landscapes and evaluate strategies to reconcile such conflicts, emphasizing the need for monitoring as an integral part of conflict reconciliation strategies.
