T1  - Interannual variation in land-use intensity enhances grassland multidiversity
JF  - Proceedings of the National Academy of Sciences of the United States of America
N2  - Although temporal heterogeneity is a well-accepted driver of biodiversity, effects of interannual variation in land-use intensity (LUI) have not been addressed yet. Additionally, responses to land use can differ greatly among different organisms; therefore, overall effects of land-use on total local biodiversity are hardly known. To test for effects of LUI (quantified as the combined intensity of fertilization, grazing, and mowing) and interannual variation in LUI (SD in LUI across time), we introduce a unique measure of whole-ecosystem biodiversity, multidiversity. This synthesizes individual diversity measures across up to 49 taxonomic groups of plants, animals, fungi, and bacteria from 150 grasslands. Multidiversity declined with increasing LUI among grasslands, particularly for rarer species and aboveground organisms, whereas common species and belowground groups were less sensitive. However, a high level of interannual variation in LUI increased overall multidiversity at low LUI and was even more beneficial for rarer species because it slowed the rate at which the multidiversity of rare species declined with increasing LUI. In more intensively managed grasslands, the diversity of rarer species was, on average, 18% of the maximum diversity across all grasslands when LUI was static over time but increased to 31% of the maximum when LUI changed maximally over time. In addition to decreasing overall LUI, we suggest varying LUI across years as a complementary strategy to promote biodiversity conservation.

T1  - Environmental factors affect acidobacterial communities below the subgroup level in Grassland and Forest Soils
JF  - Applied and environmental microbiology
N2  - In soil, Acidobacteria constitute on average 20% of all bacteria, are highly diverse, and are physiologically active in situ. However, their individual functions and interactions with higher taxa in soil are still unknown. Here, potential effects of land use, soil properties, plant diversity, and soil nanofauna on acidobacterial community composition were studied by cultivation-independent methods in grassland and forest soils from three different regions in Germany. The analysis of 16S rRNA gene clone libraries representing all studied soils revealed that grassland soils were dominated by subgroup Gp6 and forest soils by subgroup Gp1 Acidobacteria. The analysis of a large number of sites (n = 57) by 16S rRNA gene fingerprinting methods (terminal restriction fragment length polymorphism [T-RFLP] and denaturing gradient gel electrophoresis [DGGE]) showed that Acidobacteria diversities differed between grassland and forest soils but also among the three different regions. Edaphic properties, such as pH, organic carbon, total nitrogen, C/N ratio, phosphorus, nitrate, ammonium, soil moisture, soil temperature, and soil respiration, had an impact on community composition as assessed by fingerprinting. However, interrelations with environmental parameters among subgroup terminal restriction fragments (T-RFs) differed significantly, e.g., different Gp1 T-RFs correlated positively or negatively with nitrogen content. Novel significant correlations of Acidobacteria subpopulations (i.e., individual populations within subgroups) with soil nanofauna and vascular plant diversity were revealed only by analysis of clone sequences. Thus, for detecting novel interrelations of environmental parameters with Acidobacteria, individual populations within subgroups have to be considered.

T1  - Beanspruchungsmuster im Pflegeberuf : eine Studie an österreichischem Pflegepersonal im Schnittpunkt  von persönlichkeits-, gesundheits- und arbeitspsychologischem Herangehen
T1  - Strain patterns of nursing personnel
N2  - Gegenstand der Arbeit ist die Beanspruchungssituation des Pflegepersonals im Krankenhausbereich. Es wird der Frage nachgegangen, mit welchem Verhaltens- und Erlebensmuster Pflegepersonen ihren Anforderungen gegenübertreten und wie sie über die Art und Weise der persönlichen Auseinandersetzung mit den Anforderungen ihre Beanspruchungsverhältnisse mitgestalten.Den theoretischen Ausgangspunkt der Arbeit bilden salutogenetisch orientierte Ressourcenmodelle, insbesondere Beckers Modell der seelischen Gesundheit (Becker, 1982, 1986). Nach ihm hängt der Gesundheitszustand einer Person davon ab, wie gut es ihr gelingt, externe und interne Anforderungen mithilfe externer und interner Ressourcen zu bewältigen. Hier knüpft das in der Arbeit im Mittelpunkt stehende diagnostische Instrument AVEM (Arbeitsbezogenes Verhaltens- und Erlebensmuster; Schaarschmidt & Fischer, 1996, 2001) an, das die Erfassung interner Anforderungen und Ressourcen der Person sowie deren Zuordnung zu 4 Verhaltens- und Erlebensmustern gegenüber der Arbeit unter Gesundheits- und Motivationsbezug ermöglicht.Mit den Hypothesen wird angenommen, dass in Anbetracht der problematischen Arbeitsbedingungen in der Pflege eine Zurücknahme im Engagement bzw. eine Schutzhaltung vor nicht gewollten und als unangemessen empfundenen Anforderungen sowie wenig beeinflussbaren Bedingungen im Vordergrund stehen. Dort, wo zumindest partiell gesundheitsförderliche und als herausfordernd erlebte Arbeitsbedingungen anzutreffen sind, sollten günstigere Musterkonstellationen auftreten. Wir vermuteten, dass sich die ungünstigen Tendenzen bereits in der Berufsausbildung und in frühen Berufsjahren zeigen. Musterveränderungen in gesundheits- und persönlichkeitsförderlicher Hinsicht sollten durch gezielte Intervention herbeigeführt werden können. Schließlich nahmen wir an, dass die Tätigkeit und die mit ihr verbundenen Anforderungen und Ausführungsbedingungen musterspezifisch wahrgenommen werden.Zur Beantwortung der Fragen werden Ergebnisse aus verschiedenen Quer- und Längsschnittuntersuchungen herangezogen, die in Wiener Spitälern und Krankenpflegeschulen, aber auch in deutschen Krankenhäusern durchgeführt wurden. Zu Vergleichszwecken werden Befunde anderer Berufsgruppen dargestellt. Neben dem AVEM wurden weitere Fragebögen zu folgenden Inhalten eingesetzt: Arbeitsbezogene Werte, Erleben von Ressourcen in der Pflegetätigkeit, Belastungserleben und Objektive Merkmale der Arbeitstätigkeit.Die Ergebnisse bestätigen die Hypothesen in allen wesentlichen Punkten. Im Vergleich mit anderen Berufsgruppen fallen für die Pflegekräfte deutliche Einschränkungen im Arbeitsengagement auf. In Bezug auf die gesundheitlichen Risikomuster nimmt das Pflegepersonal eine Mittelstellung ein. Die Musterdifferenzierung in der Pflegepopulation lässt die stärksten Unterschiede in Abhängigkeit von der Position erkennen: Je höher die Position, desto größer ist der Anteil des Gesundheitsmusters und desto geringer ist die Resignationstendenz. Die meisten Risikomuster zeigen sich bei den Pflegekräften mit der niedrigsten Qualifikation. Für Pflegeschüler ist ein zeitweiliges starkes Auftreten von resignativen Verhaltens- und Erlebensweisen sowie eine kontinuierliche Abnahme des Engagements kennzeichnend. Dieser Trend setzt sich nach Aufnahme der Berufstätigkeit fort. Nur gezielte intensive personenorientierte Interventionen erwiesen sich als geeignet, Musterveränderungen in gesundheits- und persönlichkeitsförderlicher Hinsicht zu erreichen. Die Tätigkeit und die mit ihr verbundenen Anforderungen und Ausführungsbedingungen werden musterspezifisch wahrgenommen, wobei Personen mit eingeschränktem Engagement bzw. mit einer Resignationstendenz wesentliche Tätigkeitsmerkmale, denen persönlichkeits- und gesundheitsförderliche Wirkung zugesprochen wird, für sich als wenig wichtig beurteilen und sich mehr Defizite im Verhalten gegenüber Patienten bescheinigen.Die Ergebnisse verweisen darauf, dass im Pflegeberuf vor allem die Zurückhaltung im Engagement Anlass für eine kritische Betrachtung sein muss. Das Problem "Burnout" stellt sich in seiner Bedeutung relativiert dar. Günstigere Voraussetzungen für die Aufrechterhaltung und Förderung der Gesundheit bestehen dort, wo im konkreten Arbeitsfeld ein erweiterter Tätigkeits- und Handlungsspielraum sowie mehr Verantwortung vorliegen. Diese Befunde stehen in Einklang mit arbeitspsychologischen Ressourcenmodellen. Die Befunde zu den Pflegeschülern verweisen auf teilweise ungünstige Eignungsvoraussetzungen der Auszubildenden und legen nahe, die Angemessenheit der Anforderungen in den Krankenpflegeschulen zu hinterfragen. Hinsichtlich der Möglichkeiten der Veränderung der Muster in gesundheits- und motivationsdienlicher Weise brachten die Ergebnisse zum Ausdruck, dass verhaltensbezogenen Maßnahmen ohne gleichzeitige bedingungsbezogene Interventionen wenig Erfolg beschieden ist. Mit Blick auf die musterspezifische Wahrnehmung der Tätigkeit und der mit ihr verbundenen Anforderungen und Ausführungsbedingungen ist schließlich grundsätzlich festzuhalten, dass arbeitspsychologische Konzepte, die hohen bzw. komplexen Anforderungen und umfangreichen Freiheitsgraden in der Arbeit grundsätzlich persönlichkeits- und gesundheitsförderliche Wirkungen zuschreiben, einer Relativierung durch eine differentielle Perspektive bedürfen. Die vorgefundene Interaktion von Persönlichkeit und Arbeitsbedingungen hat zur Konsequenz, dass Verhaltens- und Verhältnisprävention in untrennbarem Zusammenhang gesehen werden sollten.
N2  - The object of this essay is the strain situation of nursing personnel in the hospital sector. We will take a look at the coping capacity of the nursing personnel, the behaviour and experience patterns with which they meet their challenges and how they co-design their present and future strain situations by means of their personal approach to these challenges.The theoretic starting points of this work are salutogenetic-oriented resource models, especially Becker's model of mental health (Becker, 1982, 1986). According to him, a person's state of health depends on how well he or she manages to cope with external and internal demands with the help of external and internal resources. The model uses the lack of satisfaction of personal requirements as a source of extraordinary strain. This is where the diagnostic instrument AVEM (Arbeitsbezogenes Verhaltens- und Erlebensmuster [work-related behaviour and experience patterns]; Schaarschmidt & Fischer, 1996, 2001) comes into the picture, which is at the center of work and helps to determine the internal requirements and resources of the person as well as the classification into 4 behaviour and experience patterns compared to working under health and motivation aspects.These hypotheses assume that reduced engagement as well as guarding against demands deemed unwanted and inappropriate together with hard to influence conditions are in the foreground when considering the problematic working conditions in the nursing profession.More favourable model constellations should occur in areas with partially health-promoting and challenging working conditions. We furthermore assume that the expected unfavourable trends already become apparent during vocational training and the early working years. It should be possible to induce pattern changes from a health and personality promotion point of view by means of targeted intervention. And finally, we assumed that the profession and its related challenges and performance conditions are perceived as patterns.In order to answer these questions, we will refer to results from various cross-section and panel studies performed in hospitals and nursing colleges in Vienna but also in German hospitals. The results obtained in other profession groups will be presented for comparison. Besides the AVEM, we applied additional questionnaires dealing with the following contents: work-related values, experiencing resources in the nursing profession, experiencing strain and objective professional features.The results confirm the hypothesis in all essential points. Compared to other profession groups in Austria, the nursing profession shows clear restrictions when it comes to work engagement. With respect to the health risk patterns, the nursing profession takes a medial position. The pattern differentiation in the nursing population shows the strongest differences depending on the position: the higher the position, the larger the share of the health pattern and the lower the resignation tendency. Most risk patterns become evident among nursing staff with the lowest qualifications. Nursing students temporarily show strong occurrences of resignation and experience patterns as well as a continuous decline in engagement. This trend continues once the vocational training is completed. Only direct, intensive and person-oriented intervention turned out to be suitable in order to achieve pattern changes with respect to promoting health and personality. In the end it turned out that the profession and its related demands and performance conditions is perceived in a pattern-specific way, whereby especially persons with restricted engagement or a trend towards resignation rate essential work features that are said to promote health and personality as less important for themselves and attribute themselves more deficits in their behaviour towards patients.The results indicate that above all restrained engagement must be critically examined in the nursing profession. The "burnout" problem, which is often seen as a central problem, is therefore relative. More favourable prerequisites for maintaining and promoting health are especially given wherever there is extended activity and action scope in the actual working environment together with more responsibility. These results coincide with the recognised work psychology models, which emphasise the effect of resources. The results obtained for nursing students indicate that part of the trainees lacks qualification. However, one also has to question the appropriateness of the demands made in nursing schools. With respect to changing the patterns in a way that suits health and motivation, the results showed that behaviour-related measures are not very successful if there are no condition-related interventions at the same time. Concerning the pattern-specific perception of the profession and its related demands and performance conditions, we conclusively have to ascertain that work psychology concepts, which generally attribute personality and health-promoting effects to high or complex demands and extensive degrees of liberty at work, require relativisation through a differential perspective. As a consequence of the encountered interaction of personality and work conditions, behaviour and condition prevention should be seen in an inseparable context.

T1  - Interacting effects of fertilization, mowing and grazing on plant species diversity of 1500 grasslands in Germany differ between regions
JF  - Basic and applied ecology : Journal of the Gesellschaft für Ökologie
N2  - The relationship of different types of grassland use with plant species richness and composition ( functional groups of herbs, legumes, and grasses) has so far been studied at small regional scales or comprising only few components of land use. We comprehensively studied the relationship between abandonment, fertilization, mowing intensity, and grazing by different livestock types on plant diversity and composition of 1514 grassland sites in three regions in North-East, Central and South-West Germany. We further considered environmental site conditions including soil type and topographical situation. Fertilized grasslands showed clearly reduced plant species diversity (-15% plant species richness, -0.1 Shannon diversity on fertilized grasslands plots of 16m(2)) and changed composition (-3% proportion of herb species), grazing had the second largest effects and mowing the smallest ones. Among the grazed sites, the ones grazed by sheep had higher than average species richness (+27%), and the cattle grazed ones lower (-42%). Further, these general results were strongly modulated by interactions between the different components of land use and by regional context: land-use effects differed largely in size and sometimes even in direction between regions. This highlights the importance of comparing different regions and to involve a large number of plots

T1  - Implementing large-scale and long-term functional biodiversity research : the biodiversity exploratories
N2  - Functional biodiversity research explores drivers and functional consequences of biodiversity changes Land use change is a major driver of changes of biodiversity and of biogeochemical and biological ecosystem processes and services However, land use effects on genetic and species diversity are well documented only for a few taxa and trophic networks We hardly know how different components of biodiversity and their responses to land use change are interrelated and very little about the simultaneous, and interacting, effects of land use on multiple ecosystem processes and services Moreover, we do not know to what extent land use effects on ecosystem processes and services are mediated by biodiversity change Thus, overall goals are on the one hand to understand the effects of land use on biodiversity and on the other to understand the modifying role of biodiversity change for land-use effects on ecosystem processes, including biogeochemical cycles To comprehensively address these Important questions, we recently established a new large-scale and long-term project for functional biodiversity, the Biodiversity Exploratories (www biodiversity-exploratories de) They comprise a hierarchical set of standardized field plots in three different regions of Germany covering manifold management types and intensities in grasslands and forests They serve as a joint research platform for currently 40 projects involving over 300 people studying various aspects of the relationships between land use biodiversity and ecosystem processes through monitoring, comparative observation and experiments We introduce guiding questions, concept and design of the Biodiversity Exploratories - including main aspects of selection and implementation of field plots and project structure - and we discuss the significance of this approach for further functional biodiversity research This includes the crucial relevance of a common study design encompassing variation in both drivers and outcomes of biodiversity change and ecosystem processes, the interdisciplinary integration of biodiversity and ecosystem researchers, the training of a new generation of integrative biodiversity researchers, and the stimulation of functional biodiversity research in real landscape contexts, in Germany and elsewhere.

T1  - High plant species richness indicates management-related disturbances rather than the conservation status of forests
JF  - Basic and applied ecology : Journal of the Gesellschaft für Ökologie
N2  - There is a wealth of smaller-scale studies on the effects of forest management on plant diversity. However, studies comparing plant species diversity in forests with different management types and intensity, extending over different regions and forest stages, and including detailed information on site conditions are missing. We studied vascular plants on 1500 20 m x 20 m forest plots in three regions of Germany (Schwabische Alb, Hainich-Dun, Schorfheide-Chorin). In all regions, our study plots comprised different management types (unmanaged, selection cutting, deciduous and coniferous age-class forests, which resulted from clear cutting or shelterwood logging), various stand ages, site conditions, and levels of management-related disturbances. We analyzed how overall richness and richness of different plant functional groups (trees, shrubs, herbs, herbaceous species typically growing in forests and herbaceous light-demanding species) responded to the different management types. On average, plant species richness was 13% higher in age-class than in unmanaged forests, and did not differ between deciduous age-class and selection forests. In age-class forests of the Schwabische Alb and Hainich-Dun, coniferous stands had higher species richness than deciduous stands. Among age-class forests, older stands with large quantities of standing biomass were slightly poorer in shrub and light-demanding herb species than younger stands. Among deciduous forests, the richness of herbaceous forest species was generally lower in unmanaged than in managed forests, and it was even 20% lower in unmanaged than in selection forests in Hainich-Dun. Overall, these findings show that disturbances by management generally increase plant species richness. This suggests that total plant species richness is not suited as an indicator for the conservation status of forests, but rather indicates disturbances.

T1  - Does organic grassland farming benefit plant and arthropod diversity at the expense of yield and soil fertility?
JF  - Agriculture, ecosystems & environment : an international journal for scientific research on the relationship of agriculture and food production to the biosphere
N2  - Organic management is one of the most popular strategies to reduce negative environmental impacts of intensive agriculture. However, little is known about benefits for biodiversity and potential worsening of yield under organic grasslands management across different grassland types, i.e. meadow, pasture and mown pasture. Therefore, we studied the diversity of vascular plants and foliage-living arthropods (Coleoptera, Araneae, Heteroptera, Auchenorrhyncha), yield, fodder quality, soil phosphorus concentrations and land-use intensity of organic and conventional grasslands across three study regions in Germany. Furthermore, all variables were related to the time since conversion to organic management in order to assess temporal developments reaching up to 18 years. Arthropod diversity was significantly higher under organic than conventional management, although this was not the case for Araneae, Heteroptera and Auchenorrhyncha when analyzed separately. On the contrary, arthropod abundance, vascular plant diversity and also yield and fodder quality did not considerably differ between organic and conventional grasslands. Analyses did not reveal differences in the effect of organic management among grassland types. None of the recorded abiotic and biotic parameters showed a significant trend with time since transition to organic management, except soil organic phosphorus concentrations which decreased with time. This implies that permanent grasslands respond slower and probably weaker to organic management than crop fields do. However, as land-use intensity and inorganic soil phosphorus concentrations were significantly lower in organic grasslands, overcoming seed and dispersal limitation by re-introducing plant species might be needed to exploit the full ecological potential of organic grassland management. We conclude that although organic management did not automatically increase the diversity of all studied taxa, it is a reasonable and useful way to support agro-biodiversity.

T1  - A quantitative index of land-use intensity in grasslands integrating mowing, grazing and fertilization
JF  - Basic and applied ecology : Journal of the Gesellschaft für Ökologie
N2  - Land use is increasingly recognized as a major driver of biodiversity and ecosystem functioning in many current research projects. In grasslands, land use is often classified by categorical descriptors such as pastures versus meadows or fertilized versus unfertilized sites. However, to account for the quantitative variation of multiple land-use types in heterogeneous landscapes, a quantitative, continuous index of land-use intensity (LUI) is desirable. Here we define such a compound, additive LUI index for managed grasslands including meadows and pastures. The LUI index summarizes the standardized intensity of three components of land use, namely fertilization, mowing, and livestock grazing at each site. We examined the performance of the LUI index to predict selected response variables on up to 150 grassland sites in the Biodiversity Exploratories in three regions in Germany(Alb, Hainich, Schorlheide). We tested the average Ellenberg nitrogen indicator values of the plant community, nitrogen and phosphorus concentration in the aboveground plant biomass, plant-available phosphorus concentration in the top soil, and soil C/N ratio, and the first principle component of these five response variables.
 The LUI index significantly predicted the principal component of all five response variables, as well as some of the individual responses. Moreover, vascular plant diversity decreased significantly with LUI in two regions (Alb and Hainich).
 Inter-annual changes in management practice were pronounced from 2006 to 2008, particularly due to variation in grazing intensity. This rendered the selection of the appropriate reference year(s) an important decision for analyses of land-use effects, whereas details in the standardization of the index were of minor importance. We also tested several alternative calculations of a LUI index, but all are strongly linearly correlated to the proposed index.
 The proposed LUI index reduces the complexity of agricultural practices to a single dimension and may serve as a baseline to test how different groups of organisms and processes respond to land use. In combination with more detailed analyses, this index may help to unravel whether and how land-use intensities, associated disturbance levels or other local or regional influences drive ecological processes.

T1  - Are gastropods, rather than ants, important dispersers of seeds of myrmecochorous forest herbs?
JF  - The American naturalist : a bi-monthly journal devoted to the advancement and correlation of the biological sciences
N2  - Seed dispersal by ants (myrmecochory) is widespread, and seed adaptations to myrmecochory are common, especially in the form of fatty appendices (elaiosomes). In a recent study, slugs were identified as seed dispersers of myrmecochores in a central European beech forest. Here we used 105 beech forest sites to test whether myrmecochore presence and abundance is related to ant or gastropod abundance and whether experimentally exposed seeds are removed by gastropods. Myrmecochorous plant cover was positively related to gastropod abundance but was negatively related to ant abundance. Gastropods were responsible for most seed removal and elaiosome damage, whereas insects (and rodents) played minor roles. These gastropod effects on seeds were independent of region or forest management. We suggest that terrestrial gastropods can generally act as seed dispersers of myrmecochorous plants and even substitute myrmecochory, especially where ants are absent or uncommon.

T1  - Grassland management intensification weakens the associations among the diversities of multiple plant and animal taxa
JF  - Ecology : a publication of the Ecological Society of America
N2  - Land-use intensification is a key driver of biodiversity change. However, little is known about how it alters relationships between the diversities of different taxonomic groups, which are often correlated due to shared environmental drivers and trophic interactions. Using data from 150 grassland sites, we examined how land-use intensification (increased fertilization, higher livestock densities, and increased mowing frequency) altered correlations between the species richness of 15 plant, invertebrate, and vertebrate taxa. We found that 54% of pairwise correlations between taxonomic groups were significant and positive among all grasslands, while only one was negative. Higher land-use intensity substantially weakened these correlations(35% decrease in rand 43% fewer significant pairwise correlations at high intensity), a pattern which may emerge as a result of biodiversity declines and the breakdown of specialized relationships in these conditions. Nevertheless, some groups (Coleoptera, Heteroptera, Hymenoptera and Orthoptera) were consistently correlated with multidiversity, an aggregate measure of total biodiversity comprised of the standardized diversities of multiple taxa, at both high and lowland-use intensity. The form of intensification was also important; increased fertilization and mowing frequency typically weakened plant-plant and plant-primary consumer correlations, whereas grazing intensification did not. This may reflect decreased habitat heterogeneity under mowing and fertilization and increased habitat heterogeneity under grazing. While these results urge caution in using certain taxonomic groups to monitor impacts of agricultural management on biodiversity, they also suggest that the diversities of some groups are reasonably robust indicators of total biodiversity across a range of conditions.
