title: Synopsis of Nardus grassland resurveys across Germany (Data Files)

description: Abstract

QuestionsHow have Nardus grasslands (i.e. unfertilised grassland on acid soils) in Germany changed in recent decades? What are the ecological drivers of these changes? Were the changes in species composition caused by the decrease in atmospheric deposition of nitrogen and sulphur and mediated by the recovery of soil pH? Have climate change and changes in management contributed to changes in species composition?

LocationSix regions within the German low mountain range and the northern Alps (230 m - 2120 m a.s.l.). 

MethodsFor a synoptic analysis of vegetation change, we compiled vegetation and soil data (pH, C:N ratio) of 375 quasi-permanent plots in Nardus grassland sampled between 1971-1989 and 2012-2021. We analysed changes in different species groups, mean ecological indicator values and soil parameters and tested for effects of time and elevation with mixed effect models. Path analyses and redundancy analysis were used to identify the drivers of vegetation change, including data on nitrogen (N) and sulphur (S) deposition, annual temperature, annual precipitation, and management.

ResultsSoil pH increased and C:N ratio decreased across study regions in Germany. We also found overall increases in mean Ellenberg indicator values for nitrogen and soil reaction. Species of nutrient-rich grasslands increased, as did total species richness. In contrast, character species of Nardus grassland and dwarf shrubs decreased. However, these patterns were less pronounced at high elevations. Declining total N and S deposition was associated with higher pH values and lower C:N ratios, which had positive effects on nutrient-demanding grassland species, and negative effects on cover of Nardus grassland character species and on dwarf shrubs. We also found indications for effects of climate warming, e.g. increased mean Ellenberg indicator values for temperature and a negative effect on character species. Management compared to abandonment had negative effects on woody species including dwarf shrubs and favoured low-growing herbaceous species. In addition, management effects contributed indirectly to eutrophication.

ConclusionNardus grasslands across Germany are affected by a decline in floristic quality associated with eutrophication (e.g. increase in nutrient indicators, decline in characteristic species). Our results suggest that after a period of airborne acidification in the 20th century, the recovery of soil pH following the reduction of acidifying sulphur and nitrogen deposition in recent decades has been a major driver of eutrophication due to improved conditions for mineralisation and nutrient release from accumulated and ongoing nitrogen deposition. An adapted management focusing on more efficient nutrient removal will be required.

title: Uniform Crime Reporting Program Data [United States]: Hate Crime Data, 1997 [Record-Type Files]
title: Archival Version

description: In response to a growing concern about hate crimes, the United States Congress enacted the Hate Crime Statistics Act of 1990. The Act requires the attorney general to establish guidelines and collect, as part of the Uniform Crime Reporting (UCR) Program, data "about crimes that manifest evidence of prejudice based on race, religion, sexual orientation, or ethnicity, including where appropriate the crimes of murder and non-negligent manslaughter, forcible rape, aggravated assault, simple assault, intimidation, arson, and destruction, damage or vandalism of property." Hate crime data collection was required by the Act to begin in calendar year 1990 and to continue for four successive years. In September 1994, the Violent Crime Control and Law Enforcement Act amended the Hate Crime Statistics Act to add disabilities, both physical and mental, as factors that could be considered a basis for hate crimes. Although the Act originally mandated data collection for five years, the Church Arson Prevention Act of 1996 amended the collection duration "for each calendar year," making hate crime statistics a permanent addition to the UCR program. As with the other UCR data, law enforcement agencies contribute reports either directly or through their state reporting programs. Information contained in the data includes number of victims and offenders involved in each hate crime incident, type of victims, bias motivation, offense type, and location type.

The Batch Header File contains a record for each law enforcement agency whether or not they reported an incident. The Batch Header File variables are merged into the Incident Record File for those agencies that reported an incident.Each victim-type variable has been split into eight separate flag variables to record each victim type. Previously, the variables were eight-character strings that contained the first letter of each victim type in any order.

These arrest reports provide data on 43 offenses including violent crime, drug use, gambling, and larceny. The data received by ICPSR were structured as a hierarchical file containing, per reporting police agency, an agency header record, 1 to 12 monthly header records, and 1 to 43 detail offense records containing the counts of arrests by age, sex, and race for a particular offense. ICPSR restructured the original data to a rectangular format.
