TLDR
In this paper, a review of the use of weighted site averages in indicator analysis is presented, showing that these have a high reliability and can complement or, in some cases, replace measurements to determine the values of environmental variables and monitor their change.About:

Topographically controlled thermal-habitat differentiation buffers alpine plant diversity against climate warming
Daniel Scherrer,Christian Körner +1 more
TL;DR: In this paper, high-resolution infra-red thermometry and large numbers of small data loggers were used to assess the spatial and temporal variation of plant surface and ground temperatures as well as snow-melt patterns for 889 plots distributed across three alpine slopes of contrasting exposure.

The use of remote sensing in soil and terrain mapping — A review
TL;DR: In this article, the use of optical and microwave remote sensing data for soil and terrain mapping with emphasis on applications at regional and coarser scales is reviewed. But, most studies so far have been performed on a local scale and only few on regional or smaller map scale.
Journal ArticleDOI
Large-scale parallel 454 sequencing reveals host ecological group specificity of arbuscular mycorrhizal fungi in a boreonemoral forest.
TL;DR: The findings suggest that partner specificity in AM symbiosis may occur at the level of ecological groups, rather than at the species level, of both plant and fungal partners.

What are indicators? On the definition of indicators in ecology and environmental planning
Ulrich Heink,Ingo Kowarik +1 more
TL;DR: This contribution analyzes different meanings of the term “indicator” in ecology and environmental planning, suggests a general definition, and makes recommendations for its appropriate use.

Changes in species richness and composition in European acidic grasslands over the past 70 years: the contribution of cumulative atmospheric nitrogen deposition
Cecilia Dupré,Carly J. Stevens,Carly J. Stevens,Traute Ranke,Albert Bleeker,Cord Peppler-Lisbach,David J. G. Gowing,Nancy B. Dise,Edu Dorland,Roland Bobbink,Martin Diekmann +10 more
TL;DR: In this paper, the negative impact of nitrogen (N) deposition on species richness in acidic grasslands was investigated based on a temporal comparison of vegetation data spanning a period of almost 70 years, in which a large data base of plots assigned to the Violion caninae grassland type, composed of managed, but unfertilized semi-natural grasslands on nutrient-poor, acidic soils.

Multivariate analysis in community ecology
TL;DR: The results can be used to improve the quality of education, research and teaching in the classroom, as well asrouse new ideas about how to teach and motivate people to learn.
Journal ArticleDOI
Diatoms and pH Reconstruction
TL;DR: Reconstruction of past lake-water pH from diatom data involves two steps; regression, where responses of modern diatom abundances to pH are modelled and calibration, where the modelled responses are used to infer pH fromdiatom assemblages preserved in lake sediments.

Reliability of Ellenberg indicator values for moisture, nitrogen and soil reaction: a comparison with field measurements
TL;DR: The Ellenberg indicator system provides a very valuable tool for habitat calibration, provided the appropriate parameters are considered, and is endorsed by Hill & Carey's (1997) suggestion that the term N-values be replaced by ‘productivity values'.
