It Is Also Obvious That the Individuals of the Same Species, Though Now Inhabiting Distant and Isolated Regions, Must Have Proceeded from One Spot “It is also obvious that the individuals of the same species, though now inhabiting distant and isolated regions, must have proceeded from one spot, where their parents were first produced.” – Darwin 1859, On the Origin of Species “Quod nullus proiceat lastadien in deep hujus civitatis, sub pena vite” “That no one throws ballast in the deep of this town, by loss of his life” – Wismar (Germany) statute, 1345 “Picture the mouth of the muddy, narrow River Tyne, jammed with four or five hundred keels and two or three hundred ships…” – John Nef, 1558 Evolution in the North Atlantic: processes shaping spatial patterns of genetic diversity in introduced intertidal invertebrates by Anthony Leon Einfeldt B.Sc.

Molecular tools provide a means of inferring past movement and contemporary barriers to movement, because the known modes of mutation and inheritance underlying genetic variation provide clear predictions for patterns arising from movement and subdivision. In this thesis, I investigate how contemporary and historic patterns of movement shape evolutionary trajectories by investigating distributions of genetic variation in focal intertidal invertebrates of the North Atlantic. To determine how movement is affected by the interaction of currents with life-history traits, I sequenced mitochondrial and nuclear DNA of the intertidal amphipod Corophium volutator from discrete patches of mudflat habitat throughout the Northwest Atlantic. I detected patterns of genetic subdivision and gene flow concordant with hydrological patterns, demonstrating that currents shape evolution by determining dispersal pathways and cause fine-scale subdivision in marine communities. To test how C. volutator colonized the Northwest Atlantic coast, I investigated spatial genetic variation in populations from across its entire range using the same markers. I found that diversity in Northwest Atlantic populations was subsampled from more genetically diverse populations in the Northeast Atlantic, consistent with historic human-mediated introduction from the Northeast to the Northwest. To investigate how human-mediated dispersal affects species’ evolutionary trajectories, I characterized genomic variation in C. volutator and a co-occurring annelid Hediste diversicolor in populations from the Northeast and Northwest Atlantic coasts. I found extensive genetic divergence between ii the introduced and native ranges and genetic patterns consistent with historic admixture between populations within each range, providing evidence that human-mediated movement can create new allopatric lineages and erase ancestral genetic structure by promoting gene flow between otherwise isolated populations. Together, my results suggest that the increasing reach, magnitude, and frequency of global human movement will change the evolutionary trajectories of species associated with human vectors of transport. While contemporary connectivity will continue to be affected by regional processes (such as currents), uncurbed human activity will likely disrupt diversification arising from barriers at regional scales while promoting the formation of new lineages at a global scale. iii DEDICATION I dedicate this thesis to my parents, Sandra and Flemming Einfeldt, who instilled in me a deep appreciation for the natural world and a desire to understand the forces behind it. I have many fond memories of how they fostered my curiosity, creativity, and confidence. Amongst the first of these memories are the weekly walks they would take me on through the woods to find a rare species of plant, which when in bloom would produce individually wrapped chocolates. The world turns out to be full of things much like the Chocolate Tree, and I thank my parents for introducing me to the thrill of discovering their true nature. iv ACKNOWLEDGEMENTS This research grew from an initial project conceived by Jason Addison to assess connectivity amongst mudflats in the Bay of Fundy, funded by NSERC through a Strategic Project Grant to Myriam Barbeau and a Discovery Grant to Jason Addison. Additional funding for the projects in this thesis was provided by a Canadian Foundation for Innovation grant to Jason Addison, a New Brunswick Innovation Foundation grant to Jason Addison and scholarship to myself, a New Brunswick Wildlife Trust Fund grant to Jason Addison and myself, and fellowships from the Fredrik and Catherine Eaton Foundation, ACENET, and the Marguerite and Murray Vaughan Foundation awarded to myself. Many thanks to my supervisor Jason Addison and committee member Linley Jesson for their guidance and support on projects in and beyond this thesis. Thanks to my other committee member Myriam Barbeau, who gave helpful feedback on my proposals and thesis. Thanks also to Mark Forbes for direction and funding at a key point. The broad geographic scope of this research was made possible with the help of many people. Sampling trips in North America were aided by Jeremy Doucet and Felix Zhou during their B.Sc. Honours in Jason Addison’s lab, Brian Nason, Jarrett Starkey- Seto, and my parents Sandra and Flemming Einfeldt. I thank the researchers who collected and sent me Corophium volutator specimens, including Myriam Barbeau, David Drolet, Guy Bachelet, Anne-Laure Barillé, Jérôme Jourde, Chloé Dancié, Julia Sigwart, Rob Hughes, Martin Solan, Annelies Debacker, Sander Wijnhoven, Ines Heisterkamp, Birgit Hussel, K. Thomas Jensen, Jacob Strand, and Andreas Bick. Thanks to Jim Provan for hosting me at Queen’s University Belfast, and to Julia Sigwart, Christine Maggs, Siobhan Rose Vye, Thomas Prebble, Nessa O’Connor, Lauren Sumner- v Rooney, Julia Calderwood, and many others for facilitating both scientific and social endeavours in Northern Ireland and Ireland. Laboratory work was helped immensely by Jin-Hong Kim Jana Gruettner, who first implemented and troubleshot the genome reduction methods used in Chapter 4. Sara Edwards was a reliable sounding board (and rubber duck) for the many coding, analysis, and writing problems that I encountered. Stephen Heard and his Nerds (particularly Chandra Moffat, Julia Mlynarek, Allyson Heustis, and Mallory MacDonnell, Ken Dearborn, and Rylee Isett) were really good at Boggle, and along with Dan Quiring and Rob Johns provided stimulating weekly presentations, discussions, constructive comments, and collaboration. The mudflat ecology group (particularly David Drolet, Diana Hamilton, Kelan Kennedy, and Trevor Bringloe) provided many discussions. This thesis was strengthened by my involvement in projects and systems not directly mentioned elsewhere in this document, which was made possible by the strong community in the UNB Biology Department. Thanks to Gary Saunders and his lab (particularly Amanda Savoie, Lesleigh Kraft, and Meghann Bruce) for ideas and discussions throughout my degree, and for spearheading a 2014 arctic sampling expedition. Thanks to Tony Diamond and his lab (particularly Kevin Kelly, Sarah Hudson, Kirsten Bowser, and Lauren Scopel) for the annual migrations to and from Machias Seal Island and the opportunities they presented. Helen Tai generously provided assistance and resources for RNA work on a project in progress that stems from the research presented here. By no means least, thank you to the graduate students at UNB and friends in Fredericton, who gave me the strength and motivation to continue this research and kept me in touch with what is truly important. vi Table of Contents ABSTRACT ........................................................................................................................ ii DEDICATION ................................................................................................................... iv ACKNOWLEDGEMENTS ................................................................................................ v Table of Contents .............................................................................................................. vii List of Tables ..................................................................................................................... xi List of Figures .................................................................................................................. xiii Chapter 1 – General introduction ........................................................................................ 1 Inferring movement from distributions of variation ....................................................... 1 Inferring movement from molecular variation ............................................................... 3 Movement and evolution in North Atlantic intertidal invertebrates ............................... 6 References ..................................................................................................................... 10 Chapter 2 – Hydrology influences population genetic structure

Changes in vegetation structure can alter the physical habitat structure, thermal environment, and food available to arthropods, which play an important role in the structure and functioning of Arctic ecosystems. Not only do they provide key ecosystem services such as pollination and nutrient cycling, they are an essential food source for migratory birds. In this study I examined the relationships between the abundance, diversity, and community composition of arthropods and the height and cover of several shrub species across a tundra-shrub gradient in northwestern Alaska. To characterize nestling diet of common passerines that occupy this gradient, I used next-generation sequencing of fecal matter. Willow cover was strongly and consistently associated with abundance and biomass of arthropods and significant shifts in arthropod community composition and diversity.

Abstract Material for the study was collected in the summer of 1994 in the Gulf of Gdańsk where specimens of Corophium volutator and Saduria entomon – organisms living in a zone of critical salinity (5–8 psu) – commonly occur. The high osmolarity of their body fluids is indicative of their adaptation effort to the salinity in their habitat. A species of marine origin, Corophium volutator maintains its osmotic concentration of haemolymph at a high level, as other species in brackish waters do; however, this is not the case with Corophium volutator specimens living in saline seas. Saduria entomon – a relict of glacial origin, originally from the Arctic Sea – also maintains a high osmotic concentration of haemolymph in comparison with specimens of this species living in the Beaufort Sea. 1. Introduction The 5–8 psu salinity zone is the boundary separating the marine world from the freshwater world, a fact stressed by many authors, e.g. Remane (1934), Khlebovich (1989, 1990a,b) or Styczyńska-Jurewicz (1972, 1974). The critical salinity is defined by Khlebovich (1990a,b) as a narrow zone where massive mortality of fresh- and salt-water forms occurs, in both estu- aries and laboratories. It limits the life activity of isolated cells and tissues, * This research was supported by grant No.

  • Preliminary Notes on the Bionomics of the Amphipod, Corophiumuolutator Panas
    [ 761 ] Preliminary Notes on the Bionomics of the Amphipod, Corophiumuolutator Panas. By T. J. Hart, B.Sc. With 4 Figures in the Text. INTRODUCTION AND PREVIOUS WORK. THE Amphipod Corophium volutator Pallas has been described, mainly from a purely systematic standpoint, under the synonyms C. grossipes Linmeus, C. longicorneLatreille, and C. bicaudatum Linneo (Della Valle). Stebbing in his standard work (19) on the Gammaridea, accepts volutator as the earliest, and modern French and Danish authors follow him. Corophium volutator is found in the greatest abundance on certain mudflats in estuarine areas round the coasts of N.W. Europe, but by no means everywhere. It appears that the nature of the substratum and the salinity of the water are two of the main factors leading to its localized distribution, and accordingly an investigation of the conditions which define its habitat is likely to throw light on some very interesting problems. These notes record the first stages of such an investigation, together with a study of the intimately related problems of the feeding habits and life- cycle of the animal. It seems that no detailed account of the feeding mechanism of any Amphipod has yet been published; though Hunt (11) gives a short and pithy description of a "filter~feeding" mechanism in Ampelisca. This author classes most of the Amphipoda he deals with as selective deposit feeders, but states that though this is true in so far as they are bottom- living forms, the actual mechanism is probably more often of a type such as would lead to their being classed under his scheme as suspension- feeders.
