Everett ACKNOWLEDGMENTS 367 APPENDIX A - GLOSSARY 368 APPENDIX B - AUTHORS 372 ECOSYSTEM MANAGEMENT: PRINCIPLES AND APPLICATIONS INTRODUCTION This document provides land managers with practical suggestions concerning the implementation of ecosystem management. It was developed in response to congressional direction for an independent, scientific evaluation of forest health in eastern Washington and Oregon (i.e., Eastside Ecosystem Health Assessment). Three science teams were formed in September 1992 to address this task: the Implementation Framework Team, the Eastside Assessment Team, and the Broad, Strategic Framework Team. The papers contained in this document represent the efforts of the Implementation Team. They were developed to: (1) document existing science principles appro- priate to ecosystem management that would provide a foundation for the efforts of the Eastside Assessment Team, and (2) provide generic guidelines for ecosystem management that would apply to most land management needs. The primary audience for this document are land managers who are increasingly being challenged to produce goods and services to society while managing for ecosystem sustainability (e.g., USDA Forest Service, USDI Bureau of Land Management, and Champion International). Accordingly, we have provided general summaries of appropriate science principles as well as recommendations for implementing those principles in management. Most of the papers in this document emphasize Forest Service examples because of the congressional direction for this document (i.e., provide a framework the Forest Service can use in sustainable ecosystem management). The topics covered, however, are also applicable to other public and private land management organizations. The papers presented also vary in technical detail. Some of the topics covered are of value to a general nontechnical audience; while others (e.g., ecological theory) are appropriate to natural resource specialists and scientists. All papers are self-contained to facilitate review of this document by a varied audience (i.e., papers may be read independent of each other). They are cross-referenced, however, to display relations among the topics covered. This document consists of five sections that address major ecosystem management issues. The first section (Historical Perspectives) presents some basic principles of ecosystem management and the historical context of their development. This section also provides general information that will be of interest to most land managers. The discussions by Jensen and Everett (ecosystem management overview), Kennedy and Quigley (social perspectives), and Shepard (political perspectives) are of particular importance because they review events that have influenced the Forest Service transition to an ecosystem management philosophy. The second section of this document (Ecological Principles) provides a summary of important theoretical con- cepts for ecosystem management. This section provides information for a more technical audience and empha- sizes the use of landscape ecology principles in land management. The topics addressed in this section (e.g., hierarchy theory, conservation biology, and ecosystem dynamics) are appropriate to ecosystem management implementation. Most of the concepts presented are not new; however, they have not commonly been explicitly addressed in previous land management efforts. We believe that if the theoretical concepts presented in this section were implemented, sustainable ecosystem management could be achieved. We do not believe that the development of new science theory is a prerequisite to ecosystem management. Instead, we emphasize the importance of using existing science principles (in more creative ways) to meet our evolving land management needs. The third section of this document (Sampling Design and Data Analysis) presents various concepts useful to the characterization and evaluation of ecosystems. Some of the papers in this section are technical and may be appropriate only to specific resource disciplines. The topics covered, however, are important to the development of cost-effective survey designs for ecosystem characterization. The reviews of data analysis methods emphasize current techniques useful in describing ecosystem process and pattern relations. The ideas presented in this section facilitate improved ecosystem description and evaluation,

Within genera, species differences in egg morphology are small and not always useful for species recognition, however eggs from one population of Calineuria are significantly different from those found in other populations and this population is given informal recognition as a possible new species.

We present a visually based method for the taxonomic identification of benthic invertebrates that automates image capture, image processing, and specimen classification. The BugID system automatically positions and images specimens with minimal user input. Images are then processed with interest operators (machine-learning algorithms for locating informative visual regions) to identify informative pattern features, and this information is used to train a classifier algorithm. Naı¨ve Bayes modeling of stacked decision trees is used to determine whether a specimen is an unknown distractor (taxon not in the training data set) or one of the species in the training set. When tested on images from 9 larval stonefly taxa, BugID correctly identified 94.5% of images, even though small or damaged specimens were included in testing.

    ORDER: PLECOPTERA (stoneflies) with special reference to those found in Utah prepared by: L. K. Hapairai, R. L. Johnson, October 2006 revised by: S. W. Judson, September 2008 Diagnosing Features, adults: hind wing usually has large anal lobe soft-bodied and flattened wings reticulated and fold flat over abdomen (Fig. 1) fore wings elongated and narrow long antennae tarsi usually 3-segmented chewing mouth parts Diagnosing Features, nymphs: flattened, generalized insect two tarsal claws (Fig. 2) two cerci (Fig. 3) wing pads usually present, especially in older nymphs long antennae Habitat: near streams or rocky lake shores, nymphs are aquatic Trophic Habits: some detritivores (shredders and more), others predators (but collectors as young) Development: hemimetabolous Preservation: alcohol, for both nymphs and adults. Notes: Stoneflies are indicators of the quality of aquatic habitats. The northern hemisphere families are often divided into two “groups”: the Euholognatha with glossa and paraglossa of equal length, and the Systellognatha with the paraglossa much larger than the glossa. In this classification care must be taken because the Peltoperlidae and Pteronarcyidae have the paraglossa and glossa of equal length, but are often placed in the Systellognatha for other reasons. The following treatments are arranged by Suborders and overall similarity of families within the suborders placed adjacently. Appendix A is a species list by UT counties. Figures: . `` Figure 1.

McIntyre1 ABSTRACT.—Patterns in the community structure of darkling beetle (9 Eleodes spp., Coleoptera: Tenebrionidae) assemblages in the shortgrass steppe of north central Colorado were monitored by live pitfall trapping for 4 summers. There were significant correlations among weather (temperature and precipitation), species richness, and number of indi- viduals per species captured; effects from weather conditions also displayed 1-month and 1-yr delayed effects. Population densities of 2 eleodid species were monitored by mark-recapture methods. Densities of these species varied relatively little among years and sites, although density was correlated with temperature and precipitation. Abiotic influences on both density and richness differed between 2 macrohabitat types (shortgrass upland, shrub floodplain).

Cover image : observed by far, the figure is the outline of a stonefly (Agnetina capitata ), however, by a closer look, it is also a long string of values, representing the codification of the organism traits. The same happens with ecology and ecotoxicology: a holistic, comprehensive view is needed to understand what is the meaning and the overall relevance of any process, but a reductionist approach is often appropriate to get a mechanistic understanding. The challenge proposed by this thesis is to achieve a correct balance between holism and reductionism, finding the right distance to see both the stonefly and the string.
