DESCRIPTION:Dr Martina Ross-Nickoll\, Institute for Environmental Research
 \, Department of Ecosystem Analysis\, Effects & Monitoring\, RWTH Aachen U
 niversity\, DE\nAbstract:\nBiodiversity is known to be the basic resource 
 maintaining and supporting ecosystem services and functions. Because biodi
 versity is realized at different levels in the complexity of a given lands
 cape\, our group is aiming to analyze and classify the distribution of dif
 ferent organism groups\, in order to elucidate the interrelationship betwe
 en diversity and structural elements in the arable landscape. After an int
 roduction\, three projects are presented that address the relationships be
 tween structural diversity in soil and agricultural landscape and (soil) b
 iodiversity.\nThe soil-zoological information System Edaphobase\, a taxono
 mic-ecological database system\, developed within a joined research projec
 t funded by the German Federal Ministry of Education and Research (BMBF) w
 ill be presented. It combines existing taxonomical primary data on soil or
 ganisms from collections\, scientific literature and reports in a data war
 ehouse. Up to now Edaphobase contains more than 500000 observations\, abou
 t 300000 sites\, an 140000 taxa. Data can easily be imported\, quality che
 cked\, published\, queried and analyzed via a web application interface. D
 etailed analyses can be performed with the interactive web application Eda
 phostat which allows species-level analysis as well as definition of refer
 ence communities. Future development of Edaphobase towards a pan-European 
 soil-biology data warehouse is presented with the aims of (1) the developm
 ent of a harmonized tool for the evaluation of ecological soil quality\, (
 2) the collection and usage of existing data from different parties all ov
 er Europe\, (3) the provision of a reference base of the ecological qualit
 y of soils and (4) the coverage of relevant needs of as many as possible E
 uropean policies.\n\nIt is widely accepted\, however controversially discu
 ssed\, that species diversity and habitats quality dramatically decrease w
 ith increasing intensity of agricultural land-use. A project is presented 
 that considers landscape structure by classifying landscape elements accor
 ding to their biodiversity of various arthropod groups. An ‘ecological v
 alue’\, reflecting the habitat quality\, is used depending on the spatia
 l distribution of typical elements of terrestrial agricultural landscapes 
 in Europe\, exemplified by two regions in Germany. We define 50 types of e
 cologically relevant landscape elements (LE-types)\, which are automatical
 ly derived from remote sensing data or land utilization data.  The method
 ology is considered well established but needs calibration by data from di
 fferent landscapes.\n\nIn the third part the concept of a new\, integrated
  monitoring scheme to assess the ecological effects of the application of 
 PPPs in the agricultural landscape of Germany will be presented. We propos
 e using synergies with an established nationwide ecological area sampling 
 site network with several\, already ongoing monitoring activities (e.g. bi
 rd monitoring and high nature value farmland). The modular structure of in
 cluding biodiversity and analytic endpoints\, as well as a planned step-by
 -step implementation will be shown.\n\nShort biography:\nMartina Roß-Nick
 oll is an expert on the ecology of biocoenoses (aiming to assess terrestri
 al field communities depending on site-specific properties)\; impact of la
 nd use and forestry on biodiversity and ecosystem services\; her work incl
 udes the development of higher tier study designs suitable for environment
 al risk assessment with focus on soil ecosystems. She currently works at t
 he Institute for Environmental Research\, RWITH Aachen University in Germa
 ny where she heads the Department of Ecosystem Analysis (ESA).\n
