TLDR
The Global Index of Vegetation-Plot Databases (GIVD) as discussed by the authors is an Internet resource aimed at registering metadata on existing vegetation plots databases to be accessible to the scientific public.Abstract:
Question: How many vegetation plot observations (releves) are
available in electronic databases, how are they geographically
distributed, what are their properties and how might they be
discovered and located for research and application? Location:
Global. Methods: We compiled the Global Index of
Vegetation-Plot Databases (GIVD; http://www.givd.info), an
Internet resource aimed at registering metadata on existing
vegetation databases. For inclusion, databases need to (i)
contain temporally and spatially explicit species co-occurrence
data and (ii) be accessible to the scientific public. This
paper summarizes structure and data quality of databases
registered in GIVD as of 30 December 2010. Results: On the
given date, 132 databases containing more than 2.4 million
non-overlapping plots had been registered in GIVD. The majority
of these data were in European databases (83 databases, 1.6
million plots), whereas other continents were represented by
substantially less (North America 15, Asia 13, Africa nine,
South America seven, Australasia two, multi-continental three).
The oldest plot observation was 1864, but most plots were
recorded after 1970. Most plots reported vegetation on areas of
1 to 1000 m2; some also stored time-series and nested-plot
data. Apart from geographic reference (required for inclusion),
most frequent information was on altitude (71%), slope aspect
and inclination (58%) and land use (38%), but rarely soil
properties (<7%). Conclusions: The vegetation plot data in GIVD
constitute a major resource for biodiversity research, both
through the large number of species occurrence records and
storage of species co-occurrence information at a small scale,
combined with structural and plot-based environmental data. We
identify shortcomings in available data that need to be
addressed through sampling under-represented geographic
regions, providing better incentives for data collection and
sharing, developing user-friendly database exchange standards,
as well as tools to analyse and remove confounding effects of
sampling biases. The increased availability of data sets
conferred by registration in GIVD offers significant
opportunities for large-scale studies in community ecology,
macroecology and global change research.read more

Ecological indicator values and life history traits of terricolous lichens of the Western Carpathians
TL;DR: In this article, a total of 271 lichen taxa from the eastern part of Central Europe in Czech Republic, Slovakia, Hungary and Austria are listed and evaluated, and their known indicator values for light conditions, climate (temperature, continentality), substratum (humidity, soil reaction-pH, nutrients, eutrophication) were reviewed or modified, and original values were established for taxa with missing information.

Risk of extinction of plant communities: Risk and assessment categories
TL;DR: Concepts related to extent of occurence (EOO), area of occupancy (AOO), extinction and regeneration of plant communities are defined, and several ranks of extinction risk based on quantitative criteria of the EOO, AOO and processes of decline are proposed.

A Significant Upward Shift in Plant Species Optimum Elevation During the 20th Century
TL;DR: This study shows that climate warming has resulted in a significant upward shift in species optimum elevation averaging 29 meters per decade, which is larger for species restricted to mountain habitats and for grassy species, which are characterized by faster population turnover.

TL;DR: Records from multiple long-term monitoring plots across Amazonia are used to assess forest responses to the intense 2005 drought, a possible analog of future events that may accelerate climate change through carbon losses and changed surface energy balances.
