What does that mean for us scientists, policy makers and managers? Well – firstly, we won’t run out of work…, but Kati Doehring more importantly, it means that our knowledge of freshwater N t EWSLEt ER EDItOR systems is more valued than ever. We have reached a phase, where government have finally started to consult on the ‘real deal’, asking for advice to assist them in decision-making processes. this doesn’t automatically mean that everything we say is listened to, included and implemented, but we all know that ‘good things take time’, so if we take one little step after another we’ll get there in the end. After all, our rivers and lakes didn’t get to the state they are in now overnight. 4 Photo © Organisation, Name Number 53 • September 2014 As the sun sets over Lake Rotorua (Kaikōura), the final samples from a mesocosm experiment are collected.

    CRITICAL HABITAT FOR CANTERBURY FRESHWATER FISH, KŌURA/KĒKĒWAI AND KĀKAHI REPORT PREPARED FOR CANTERBURY REGIONAL COUNCIL BY RICHARD ALLIBONE WATERWAYS CONSULTING REPORT NUMBER: 55-2018 AND DUNCAN GRAY CANTERBURY REGIONAL COUNCIL DATE: DECEMBER 2018 EXECUTIVE SUMMARY Aquatic habitat in Canterbury supports a range of native freshwater fish and the mega macroinvertebrates kōura/kēkēwai (crayfish) and kākahi (mussel). Loss of habitat, barriers to fish passage, water quality and water quantity issues present management challenges when we seek to protect this freshwater fauna while providing for human use. Water plans in Canterbury are intended to set rules for the use of water, the quality of water in aquatic systems and activities that occur within and adjacent to aquatic areas. To inform the planning and resource consent processes, information on the distribution of species and their critical habitat requirements can be used to provide for their protection. This report assesses the conservation status and distributions of indigenous freshwater fish, kēkēwai and kākahi in the Canterbury region. The report identifies the geographic distribution of these species and provides information on the critical habitat requirements of these species and/or populations.

Box 56, Dunedin 9054, New Zealand; [email protected] * Correspondence: [email protected]; Tel.: +47-481-37-867 Abstract: Free-living species often receive greater conservation attention than the parasites they support, with parasite conservation often being hindered by a lack of parasite biodiversity knowl- edge. This study aimed to determine the current state of knowledge regarding parasites of the Southern Hemisphere freshwater fish family Galaxiidae, in order to identify knowledge gaps to focus future research attention. Specifically, we assessed how galaxiid–parasite knowledge differs among geographic regions in relation to research effort (i.e., number of studies or fish individuals examined, extent of tissue examination, taxonomic resolution), in addition to ecological traits known to influ- ence parasite richness. To date, ~50% of galaxiid species have been examined for parasites, though the majority of studies have focused on single parasite taxa rather than assessing the full diversity of macro- and microparasites. The highest number of parasites were observed from Argentinean galaxiids, and studies in all geographic regions were biased towards the highly abundant and most widely distributed galaxiid species, Galaxias maculatus.

When their wetland habitats dry out in summer, they burrow into the soil and remain there, motionless, breathing air, until the first decent flood of autumn refills the wetland and washes them from their refuge. Few fish species worldwide have such ability to survive for extended periods out of water. Early settlers in New Zealand were surprised to find live fish when digging vegetables from the earth. This ability to survive prolonged periods of drought allows them to colonise habitats that would be unsuitable for conventional fishes, which cannot survive out of water. These cryptic, nocturnal fish were probably once the most abundant freshwater fish in New Zealand. However, the loss of more than 90% of our wetlands over the past two centuries has confined them to a few refuge habitats still threatened by development of adjacent land.

  • Rediscovering the Species in Community-Wide Predictive Modeling
    Ecological Applications, 16(4), 2006, pp. 1449–1460 Ó 2006 by the the Ecological Society of America REDISCOVERING THE SPECIES IN COMMUNITY-WIDE PREDICTIVE MODELING 1,3 2 2 JULIAN D. OLDEN, MICHAEL K. JOY, AND RUSSELL G. DEATH 1Center for Limnology, University of Wisconsin–Madison, 680 N. Park Street, Madison, Wisconsin 53706 USA 2Institute of Natural Resources–Ecology, Massey University, Private Bag 11 222, Palmerston North, New Zealand Abstract. Broadening the scope of conservation efforts to protect entire communities provides several advantages over the current species-specific focus, yet ecologists have been hampered by the fact that predictive modeling of multiple species is not directly amenable to traditional statistical approaches. Perhaps the greatest hurdle in community-wide modeling is that communities are composed of both co-occurring groups of species and species arranged independently along environmental gradients. Therefore, commonly used ‘‘short-cut’’ methods such as the modeling of so-called ‘‘assemblage types’’ are problematic. Our study demonstrates the utility of a multiresponse artificial neural network (MANN) to model entire community membership in an integrative yet species-specific manner. We compare MANN to two traditional approaches used to predict community composition: (1) a species-by-species approach using logistic regression analysis (LOG) and (2) a ‘‘classification-then-modeling’’ approach in which sites are classified into assemblage ‘‘types’’ (here we used two-way indicator species analysis and multiple discriminant analysis [MDA]). For freshwater fish assemblages of the North Island, New Zealand, we found that the MANN outperformed all other methods for predicting community composition based on multiscaled descriptors of the environment.

    25 Using Community Group Monitoring Data To Measure The Effectiveness Of Restoration Actions For Australia's Woodland Birds Michelle Gibson1, Jessica Walsh1,2, Nicki Taws5, Martine Maron1 1Centre for Biodiversity and Conservation Science, School of Earth and Environmental Sciences, University of Queensland, St Lucia, Brisbane, 4072, Queensland, Australia, 2School of Biological Sciences, Monash University, Clayton, Melbourne, 3800, Victoria, Australia, 3Greening Australia, Aranda, Canberra, 2614 Australian Capital Territory, Australia, 4BirdLife Australia, Carlton, Melbourne, 3053, Victoria, Australia, 5Greening Australia, PO Box 538 Jamison Centre, Macquarie, Australian Capital Territory 2614, Australia Before conservation actions are implemented, they should be evaluated for their effectiveness to ensure the best possible outcomes. However, many conservation actions are not implemented under an experimental framework, making it difficult to measure their effectiveness. Ecological monitoring datasets provide useful opportunities for measuring the effect of conservation actions and a baseline upon which adaptive management can be built. We measure the effect of conservation actions on Australian woodland ecosystems using two community group-led bird monitoring datasets. Australia’s temperate woodlands have been largely cleared for agricultural production and their bird communities are in decline. To reverse these declines, a suite of conservation actions has been implemented by government and non- government agencies, and private landholders. We analysed the response of total woodland bird abundance, species richness, and community condition, to two widely-used actions — grazing exclusion and replanting. We recorded 139 species from 134 sites and 1,389 surveys over a 20-year period. Grazing exclusion and replanting combined had strong positive effects on all three bird community metrics over time relative to control sites, where no actions had occurred.

Signed Summary This study used two distinct methods to infer phylogenetic relationships of members of the Galaxioidea. The first approach involved direct sequencing of mitochondrial DNA to produce a molecular phylogeny. Secondly, a thorough osteological study of the galaxiines was the basis of a cladistic analysis to produce a morphological phylogeny. Phylogenetic analysis of 303 base pairs of mitochondrial cytochrome b _supported the monophyly of Neochanna, Paragalaxias and Galaxiella. This gene also reinforced recognised groups such as Galaxias truttaceus-G. auratus and G. fasciatus-G. argenteus. In a previously unrecognised grouping, Galaxias olidus and G. parvus were united as a sister clade to Paragalaxias. In addition, Nesogalaxias neocaledonicus and G. paucispondylus were included in a clade containing G.
