ABSTRACT Military installations in the Sand Hills ecoregion of the Atlantic Coastal Plain protect unique ecosystems including blackwater streams. The Department of Defense is committed to the recovery of degraded ecosystems but lacks reference models that specify end-states representative of least disturbed conditions. This project developed ecological reference models and assessment frameworks for evaluating the ecological integrity of coastal plain streams. The models were based on biological, habitat, and watershed data collected from undeveloped areas within major DoD installations and other protected lands. Ecological reference models were developed for fish communities, macroinvertebrate communities, and stream hydrogeomorphic conditions. The models provided a basis for multimetric indices, predictive models, and other assessment frameworks that measured deviations from reference model objectives. Habitat data were analyzed to interpret biological responses and identify factors that could affect recovery success. Performance evaluations indicated that most methods performed well at highly disturbed sites and that the concomitant use of fish and macroinvertebrate methods resulted in greater ability to detect degradation. The assessment frameworks provide tools that can be used to monitor the ecological health of wadeable streams and assess their recovery to reference states characteristic of least disturbed conditions or best attainable conditions imposed by factors that limit recovery. 15.

    L.7. Calculation of Minnesota Macroinvertebrate IBIs- Draft January 26, 2017 Introduction The Index of Biotic Integrity (IBI) is one of the primary tools used by the Minnesota Pollution Control Agency (MPCA) to determine if streams are meeting their aquatic life use goals. Calculation of an IBI involves the synthesis of macroinvertebrate community information into a numerical expression of stream health. In order to apply the MPCA Macroinvertebrate IBI (MIBI) to a macroinvertebrate dataset, it is essential that all data is collected using MPCA field and laboratory protocols (MPCA 2004, MPCA 2015). This document details the process for calculating the Minnesota MIBIs from raw macroinvertebrate samples. Summary of MIBI development To account for natural differences in macroinvertebrates communities in Minnesota, streams are assigned to different stream types. These stream types use different MIBI models and biocriteria to determine the condition of the macroinvertebrate assemblage and their attainment or nonattainment of the aqutic life beneficial use. The MPCA stratified Minnesota streams into nine macroinvertebrate stream types based on the expected natural composition of stream macroinvertebrates (Table 1). Stream type is differentiated by drainage area, geographic region, thermal regime, and gradient. These stream types are used to determine thresholds (i.e., biocriteria) that interpret the calculated MIBI as meeting or exceeding the aquatic life use goal. MIBIs were developed from five individual invertebrate stream groups, with large rivers, wadable high gradient and wabable low gradient stream types each being combined for the purposes of metric testing and evaluation. A complete description of the development of MIBIs can be found in MPCA (2014).

    NEW RECORDS OF CHIRONOMIDAE (DIPTERA) FROM CONTINENTAL FRANCE Joel Moubayed-Breil Applied ecology, 10 rue des Fenouils, 34070-Montpellier, France, Email: [email protected] Abstract Material recently collected in Continental France has allowed me to generate a list of 83 taxa of chironomids, including 37 new records to the fauna of France. According to published data on the chironomid fauna of France 718 chironomid species are hitherto known from the French territories. The nomenclature and taxonomy of the species listed are based on the last version of the Chironomidae data in Fauna Europaea, on recent revisions of genera and other recent publications relevant to taxonomy and nomenclature. Introduction French territories represent almost the largest Figure 1. Major biogeographic regions and subregions variety of aquatic ecosystems in Europe with of France respect to both physiographic and hydrographic aspects. According to literature on the chironomid fauna of France, some regions still are better Sites and methodology sampled then others, and the best sampled areas The identification of slide mounted specimens are: The northern and southern parts of the Alps was aided by recent taxonomic revisions and keys (regions 5a and 5b in figure 1); western, central to adults or pupal exuviae (Reiss and Säwedal and eastern parts of the Pyrenees (regions 6, 7, 8), 1981; Tuiskunen 1986; Serra-Tosio 1989; Sæther and South-Central France, including inland and 1990; Soponis 1990; Langton 1991; Sæther and coastal rivers (regions 9a and 9b).

  • Chironominae 8.1
    CHIRONOMINAE 8.1 SUBFAMILY CHIRONOMINAE 8 DIAGNOSIS: Antennae 4-8 segmented, rarely reduced. Labrum with S I simple, palmate or plumose; S II simple, apically fringed or plumose; S III simple; S IV normal or sometimes on pedicel. Labral lamellae usually well developed, but reduced or absent in some taxa. Mentum usually with 8-16 well sclerotized teeth; sometimes central teeth or entire mentum pale or poorly sclerotized; rarely teeth fewer than 8 or modified as seta-like projections. Ventromental plates well developed and usually striate, but striae reduced or vestigial in some taxa; beard absent. Prementum without dense brushes of setae. Body usually with anterior and posterior parapods and procerci well developed; setal fringe not present, but sometimes with bifurcate pectinate setae. Penultimate segment sometimes with 1-2 pairs of ventral tubules; antepenultimate segment sometimes with lateral tubules. Anal tubules usually present, reduced in brackish water and marine taxa. NOTESTES: Usually the most abundant subfamily (in terms of individuals and taxa) found on the Coastal Plain of the Southeast. Found in fresh, brackish and salt water (at least one truly marine genus). Most larvae build silken tubes in or on substrate; some mine in plants, dead wood or sediments; some are free- living; some build transportable cases. Many larvae feed by spinning silk catch-nets, allowing them to fill with detritus, etc., and then ingesting the net; some taxa are grazers; some are predacious. Larvae of several taxa (especially Chironomus) have haemoglobin that gives them a red color and the ability to live in low oxygen conditions. With only one exception (Skutzia), at the generic level the larvae of all described (as adults) southeastern Chironominae are known.

Analyses indicate assemblages adapted to low oxygen conditions during the entire sequence. Major changes in the chironomid fauna were inferred (1) at the beginning of the Lateglacial Interstadial, when taxa adapted to oligo-mesotrophic northern and mountain lakes disappeared from the record, (2) at the beginning of the Younger Dryas cold phase when chironomid concentrations declined, suggesting increased anoxia in the lake, and many taxa typical for temperate lowland lakes disappeared from the record, and (3) at the end of the Younger Dryas when most taxa adapted to temperate conditions returned. A chironomid-July air temperature transfer function from Central Europe was applied to the record and reconstructed July air temperatures of 10.5-10.8 °C before the Lateglacial Interstadial, 13.8-13.9 °C during most of the Interstadial with a slight increase to 15.3 °C just before the Younger Dryas, variable temperatures of 11.7-14.5 °C during the Younger Dryas and temperatures of 15.8-16.4 °C during the earliest Holocene.

  • Empirically Derived Indices of Biotic Integrity for Forested Wetlands, Coastal Salt Marshes and Wadable Freshwater Streams in Massachusetts
    Empirically Derived Indices of Biotic Integrity for Forested Wetlands, Coastal Salt Marshes and Wadable Freshwater Streams in Massachusetts September 15, 2013 This report is the result of several years of field data collection, analyses and IBI development, and consideration of the opportunities for wetland program and policy development in relation to IBIs and CAPS Index of Ecological Integrity (IEI). Contributors include: University of Massachusetts Amherst Kevin McGarigal, Ethan Plunkett, Joanna Grand, Brad Compton, Theresa Portante, Kasey Rolih, and Scott Jackson Massachusetts Office of Coastal Zone Management Jan Smith, Marc Carullo, and Adrienne Pappal Massachusetts Department of Environmental Protection Lisa Rhodes, Lealdon Langley, and Michael Stroman Empirically Derived Indices of Biotic Integrity for Forested Wetlands, Coastal Salt Marshes and Wadable Freshwater Streams in Massachusetts Abstract The purpose of this study was to develop a fully empirically-based method for developing Indices of Biotic Integrity (IBIs) that does not rely on expert opinion or the arbitrary designation of reference sites and pilot its application in forested wetlands, coastal salt marshes and wadable freshwater streams in Massachusetts. The method we developed involves: 1) using a suite of regression models to estimate the abundance of each taxon across a gradient of stressor levels, 2) using statistical calibration based on the fitted regression models and maximum likelihood methods to predict the value of the stressor metric based on the abundance of the taxon at each site, 3) selecting taxa in a forward stepwise procedure that conditionally improves the concordance between the observed stressor value and the predicted value the most and a stopping rule for selecting taxa based on a conditional alpha derived from comparison to pseudotaxa data, and 4) comparing the coefficient of concordance for the final IBI to the expected distribution derived from randomly permuted data.
