The present study aimed to add Staphylinidae to the known faunal composition of the Panguana area, a hotspot of biodiversity worldwide. The investigation is based mainly on the material collected by W. Hanagarth and M. Verhaagh but it also includes species described from the area and collected by other scientists. From the total of 1470 specimens,...
Coastal zones at the German North Sea and the Baltic Sea were essentially caused by climate changes in the past. Humans have affected the dynamics of these systems by coastal protection and land reclamation. The salt marshes are regarded as one of the most natural ecosystems in Central Europe. At the same time, their function for coastal protection...
An experimental approach was performed under controlled laboratory conditions to find the effects of the increasing sea level on two carabid species. Inundation frequencies were executed in three basins with transplanted salt marsh. The inundation frequencies were arranged according to the two climate scenarios and a control basin under present inu...
In this chapter, the main results of the study are comprised and conclusions were made separately for the North Sea and the Baltic Sea coast. The integrated results regarded temperature and sea level changes and included soil processes and the biotic systems separated for vegetation and animal communities. Additionally, management impacts such as d...
This chapter reviews the knowledge hitherto available for coastal arthropod groups under study: Many species of the epigaeic ground beetles (Carabidae) and spiders (Araneae) are well-known as indicators for natural and man-made changes of environmental factors and habitats. Basic aspects were geographical distribution, the sequences of zones in the...
The expert system considers spiders and ground beetles in the study region with a total of 35 spider species and 37 ground beetle species. Distribution in Europe and along the North Sea coast and Baltic Sea coast is regarded separately. Traits, such as zonation, flooding tolerance, salt tolerance, etc., were noted.
An experimental approach was executed in one salt marsh in western Schleswig-Holstein to analyse the reaction of soil processes under a 5°K higher temperature conditions using a heating construction installed in 1 m depth. Microbial activity and soil faunal changes were studied. Changes in soil processes caused only by the temperature increase were...
Flooding conditions represent the major factor influencing the composition of the salt grassland ground beetle and spider communities at the North Sea and the Baltic Sea coasts. They lead to a decreasing species richness from high to low elevated sites. Above MHW level, two to three assemblages have been differentiated along the zonation of salt gr...
The study aimed to investigate the effect on litter decomposition of the geographical and land-use gradient from the dry Cerrado in Mato Grosso to the southern Amazonian rainforest in Pará, Brazil. The study area also represents a gradient of land-use intensification, reaching from the southern Cerrado region which had the most active land use chan...

The present study is based on a 20-year study of fields that were previously farmed conventionally and then changed to being farmed organically and a 10-year study of a conventionally farmed field in south-eastern and central Schleswig-Holstein, North Germany, respectively. The carabid beetles were sampled throughout each year using pitfall traps....
Ground beetle species from marginal areas invade organically farmed fields in a higher abundance and species richness than conventionally farmed fields. Seasonal invasion into organic fields was studied at Ritzerau Manor, converted to organic farming 18 years ago. Carabid species were explored with 123 pitfall traps within the field and in marginal...
Biomass estimations are currently needed to explain the insect decline of the past 30 years. As pitfall trapping is the most frequently performed method in carabid studies, it is necessary to question whether this method is appropriate for biomass studies. The results of pitfall trapping have often been accepted without considering the limits of th...

The succession of all fields...
Restingas are sandy areas spread along the Brazilian coast made up of a mosaic of forest and open woodland vegetation adapted to varying conditions of aridity, oligotrophy and salinity. Two vegetation types are very common in southeast Brazilian restingas, open Clusia formations and seasonally dry forest formation. Litter production and nutrient (C...
Two new species are described from Brazil: Gnathymenus schubarti sp.n. (Staphylinidae: Paederinae) from Rio de Janeiro, and Piestus amazonensis sp.n. (Staphylinidae: Piestinae) from Amazonas. Their distribution and ecology are shortly discussed.
The changes of the ground beetle assemblages during the 15 years succession after the conversion from conventional to organic farming was investigated in northern Germany, with the aim to find trends for the communities on organically farmed fields. The succession showed that the carabid assemblages developed from typically wide-spread communities...

An overview over the number of genera is given for all Central and South American countries. The subfamily Osoriinae is described in more detail. The simil...
This chapter aims to give a review about the impact of environmental conditions on Staphylinidae. Densities in diverse ecosystems from northern to tropical and from marine to alpine ecosystems are listed. As most Staphylinidae belong to the soil fauna, soil conditions are of main interest. Thus, life forms of soil-dwelling species are described. Th...
A short overview of the evolution of rove beetles is given to introduce to the reader the topics contained in the book.

Rove beetles (Staphylinidae) are common elements of the soil biota, living in the litter and deeper soil layers. Although they are one of the most diverse and speciose groups of insects, no comprehensive books on their general evolution and ecology are as yet available. This book fills that gap, discussing significant aspects and active research ex...
Game and biodiversity: Beetle assemblages in game and cattle dung
The relevance of game for the diversity of dung-inhabiting beetles was investigated in Schleswig-Holstein (Northern Germany) in the year 2010. Dung of wild boar (Sus scrofa), red deer (Cervus elaphus), roe deer (Capreolus capreolus), and fallow deer (Dama dama) was used for the inve...
In the past four decades, Mato Grosso in Central-West Brazil has undergone rapid changes from forested area to pasture and/or cropland. Yet, little is known about how these changes affect litter turnover and nitrogen (N) and carbon (C) cycling. We carried out litter breakdown experiments with litter mesh bags and investigated the effects of five fa...
