Rothlisberger David M. Lodge, Director Graduate Program in Biological Sciences Notre Dame, Indiana August 2009 HUMAN-MEDIATED DISPERSAL OF AQUATIC NONINDIGENOUS SPECIES: IMPACTS AND INTERVENTIONS Abstract by John D. Rothlisberger The introduction and establishment of species beyond the boundaries of their native ranges is an environmental issue of increasing scope and seriousness. This dissertation examines the consequences of the establishment of aquatic nonindigenous species (NIS) in the Laurentian Great Lakes (GL) region and also investigates alternatives for reducing anthropogenic spread of nuisance aquatic NIS. I first investigate the pathways by which aquatic NIS are introduced to the GL to learn if introduction pathway is related to where species originate and how likely they are to have spread beyond the GL basin. My analysis shows that ballast water release is highly likely to introduce new aquatic NIS to North America, whereas unauthorized release of organisms in trade tends to introduce to the GL aquatic NIS already established in North America. Moreover, it appears that it is primarily a matter of time before novel NIS that become established in the GL appear in other North American waterways. I also consider the relationship between introduction pathway and species impacts, finding that John D. Rothlisberger there is an apparent relationship, but that further study of species-specific impacts is needed to verify this finding. Given the importance of ballast water release in bringing novel species to the GL, I use a novel technique to estimate the economic impacts in the region of ecological changes caused by populations of aquatic NIS introduced by this pathway. This study concludes that the economic impacts of ballast water species are large, but are also uncertain. Nevertheless, policies that aim to reduce the likelihood of additional invasions via this pathway appear to be economically justifiable. As nuisance aquatic NIS in the GL region spread to other waterways, they bring with them ecological and economic impacts. The detrimental nature of these impacts motivates efforts to reduce the rate of spread. To inform such efforts, I test the efficacy of multiple methods for removing aquatic NIS from recreational boats and trailers. I found that visual inspection and hand removal is highly effective in removing the nuisance macrophyte Myriophyllum spicatum, but that high-pressure washing is needed to effectively remove small-bodied organisms, including the exotic predatory zooplankter Bythotrephes longimanus. Beyond the tactics of how to clean boats, I evaluate efforts to strategically place boat cleaning stations on the landscape. My results show that a common predictive model is limited in its ability to predict which uninvaded lakes cleaning stations should protect. Instead, it appears that placing cleaning stations at invaded lakes to block the transport of invasive propagules is generally more likely to reduce landscape-level spread than protecting uninvaded lakes. John D. Rothlisberger Aquatic NIS are only one of many environmental and cultural factors that affect ecosystems and societal interactions with the natural environment. To put the importance of aquatic NIS in context with other potential drivers of change in GL fisheries over the next two decades, I interviewed experts on GL fisheries, asking them to predict changes and to identify the most likely drivers of the changes they predicted. This study revealed that changing cultural interests are the main reason for expected declines in GL fisheries, but that NIS are the predominant environmental driver of change. The ecological and social issues surrounding NIS are complex and multi-faceted. As human populations grow, causing global environmental changes and taxing the supply of natural resources, the line separating ecological concerns from social ones is increasingly blurred. In this dissertation, I have included humans as a key component of the ecosystems of the GL region and considered the ecological effects of human actions with respect to their introduction of and intervention against aquatic NIS. In so doing, this dissertation presents several case studies of aquatic NIS in the GL with the aim of providing insights regarding opportunities and pitfalls for efforts to improve NIS policy and management. To my parents, Dana and Ann. Thank you for your love and support. ii CONTENTS Figures............................................................................................................................... vii Tables

New and modified classes appear every year and it is important to gather information and review results as quickly as possible. For dinghy classes there have been no changes to the original Yardsticks published for the 2013/14 season, as results for review have not been forthcoming. In the absence of race results data for dinghy classes and new internationally sourced classes, where there is yardstick data from overseas available, a comparison is made with other international classes to derive an equivalent Yachting Victoria yardstick value. This is explained further down in this document. Fortunately for catamaran classes, there has been significant work done by the Kurnell Catamaran Club in reviewing various catamaran ratings, as well as validating the ratings against the international SCHRS system. This work has now been incorporated into the YV yardsticks for catamaran classes. Much appreciation goes to KCC for this good work. Catamaran yardsticks are now contained in a separate document: “YV - Cat Yardsticks13_14 v1.0” USE OF THE YV YARDSTICKS A club which intends to run a race or event under the Yachting Victoria Yardstick system should include in the Notice of Race and in the Sailing Instructions clauses based on the following: 1 The version of the YV Yardstick System that is to be used in calculating the mixed class fleet racing results.

    01 OCTOBER 2011 CEH CODE LIST FOR RECORDING THE MACROINVERTEBRATES IN FRESH WATER IN THE BRITISH ISLES CYNTHIA DAVIES AND FRANÇOIS EDWARDS CEH Code List For Recording The Macroinvertebrates In Fresh Water In The British Isles October 2011 Report compiled by Cynthia Davies and François Edwards Centre for Ecology & Hydrology Maclean Building Benson Lane Crowmarsh Gifford, Wallingford Oxfordshire, OX10 8BB United Kingdom Purpose The purpose of this Coded List is to provide a standard set of names and identifying codes for freshwater macroinvertebrates in the British Isles. These codes are used in the CEH databases and by the water industry and academic and commercial organisations. It is intended that, by making the list as widely available as possible, the ease of data exchange throughout the aquatic science community can be improved. The list includes full listings of the aquatic invertebrates living in, or closely associated with, freshwaters in the British Isles. The list includes taxa that have historically been found in Britain but which have become extinct in recent times. Also included are names and codes for ‘artificial’ taxa (aggregates of taxa which are difficult to split) and for composite families used in calculation of certain water quality indices such as BMWP and AWIC scores. Current status The list has evolved from the checklist* produced originally by Peter Maitland (then of the Institute of Terrestrial Ecology) (Maitland, 1977) and subsequently revised by Mike Furse (Centre for Ecology & Hydrology), Ian McDonald (Thames Water Authority) and Bob Abel (Department of the Environment). That list was subject to regular revisions with financial support from the Environment Agency.

    WILDLIFE DIARY AND NEWS FOR DEC 28 - JAN 3 (WEEK 53 OF 2015) Fri 1st January 2016 54 Birds and 45 Flowers to start the year In my garden just before sunrise the moon was close to Jupiter high in the southern sky and Robins and a Song Thrush were serenading it from local gardens as a Carrion Crow flew down to collect the sraps of bread I threw out on the lawn before setting out on my bike in search of birds. Also on my lawn I was surprised to see that a Meadow Waxcap fungus had sprung up a couple of weeks after I thought my garden fungus season was over - later I added another fungus to my day list with a smart fresh Yellow Fieldcap (Bolbitius vitellinus) growing from a cowpat on the South Moors Internet photos of Yellow Fieldcap and Meadow Waxcap My proposed route was along the shore from Langstone to Farlington Marshes lake and as the wind was forecast to become increasingly strong from the south- east, and the tide to be rising from low at 9.0am I thought it best to follow the shore with the wind behind me on the way out and to stick to the cycle track and roads on the way home so I rode down Wade Court Road listening out for garden birds among which I heard bursts of song from more than one Dunnock (not a bird I associate with winter song) and saw two smart cock Pheasants in the horse feeding area immediately south of Wade Court.
