Photo: Margaret Moseley December 2013 Volume 138 Number 1084 Terry Whitaker, President of the YNU 2013-2014 - an informal biography I was born in Leeds in September 1947 but as my parents moved around the country I lived in Leicestershire, Derbyshire, Warwickshire and Aberystwyth. My interest in natural history started in Hillmorton, then a rural village on the outskirts of Rugby, where I developed an early interest in wild flowers, raised Grass Snakes and, though now ashamed to admit it, indulged in minor birds’ egg collecting. Moving to Aberystwyth I explored the then unspoiled countryside and mountains of West Wales. The seashore was a new and fascinating experience. I fished the rivers and shot in the woods, often in the company of much older countrymen who were great observers of the natural world. As a teenager I bicycled into the hills to observe the nests of the remaining six pairs of UK Red Kites, down to Aberaeron to see the first Collared Doves and explored the many local lead mines with my bike lamp. On field meetings with members of the West Wales Naturalists I met William (Bill) Condry who became a natural history rôle model for me. At this time he was warden of Ynys-hir RSPB Reserve and writing his book on the Snowdonia National Park which became a classic in the Collins New Naturalist series. My obsession with butterflies and moths developed, raising caterpillars of the then common Garden Tiger, Oak Eggar and Lackey moths. As a grammar school boy I bought a mercury vapour light moth trap and also ran a RIS trap for two years. The Naturalist 138 (2013) 161 Returning to Yorkshire to take Zoology at Leeds University, I spent more time in running the caving club and walking in the Yorkshire Dales than in academic endeavour. At this time I met and became firm friends with a then junior lecturer, Stephen Sutton, who fostered my interest in entomology and expeditions. On leaving Leeds with a mediocre degree and after a spell as a machinist in an engineering works, I went to Wolverhampton Polytechnic to do MIBiol in entomology. My work experience for the course was in the Entomology Department at Rothamsted Experimental Station. This was an inspiring experience. At that time C B Williams was departmental head and the numerical ecologists Roy Taylor and Trevor Lewis were working just down the corridor. Ian Woiwod was then a junior assistant and drinking companion. Having once said I had no interest in marine biology and wanted to work on crop pests, I logically found employment with the British Antarctic Survey as a marine biologist in a fisheries research group where I worked on marine phytoplankton ecology and seawater chemistry and had eleven splendid years seeing most of the interesting animals of the Falkland Islands and the Antarctic Peninsula. During this time I made good academically by writing up my researches for a PhD in Botany at the University of London. The pull of ‘God’s own county’ eventually overcame the delights of the agricultural desert that is the countryside around Cambridge and I moved to the borders of the Yorkshire Dales where I needed to earn my living as a builder. However, I was able to indulge in caving and walking and get paid for my natural history interests by doing occasional work for English Nature and the Yorkshire Dales National Park. Imagine my surprise at finding that my once junior lecturer, Stephen Sutton, was living just up the road. He was now a senior academic and a President of the YNU and writing Sutton & Beaumont's Moths and Butterflies of Yorkshire. He set my feet firmly back into Lepidopteran studies, mainly in Southeast Asia. Since then I have been exploring the natural history delights of the Dales, interspersed with sporadic caving expeditions world-wide and more regular visits to the Cantabrian Mountains. In the last ten years I became involved full time in biological consultancy and started a project to produce a definitive pictorial guide to the pyralid and thyridid moths of Borneo. Recently I have been involved with Australian, Malaysian and Chinese colleagues in the lepidopteran components of major biodiversity studies in Borneo and China. Currently I am still avoiding becoming formally retired due to the syndrome of the ‘rolling stone having gathered no moss’ and I am still working on conservation and survey projects, some paid and some voluntary, in the Dales and around my midwinter home at Matienzo in the Cantabrian Mountains. Like all true biological organisms the Bornean pyralid moth project is now evolving into a web-based identification and taxonomy site (http://www.pyralidsofborneo.org/) which will enable me to while away my dotage in front of a hot computer, happily uploading new descriptions. The Naturalist 138 (2013) 162 River Aire Fish Populations 2012 Kevin Sunderland Bingley [email protected] Introduction The last list of fish in the River Aire was The Fishes of Upper Airedale by Wm H Whitaker of Utley (Whitaker 1910). It was far easier to compile an accurate list at that time as there were thought to be no fish populations downstream of Shipley where the grossly polluted Bradford Beck entered the river. The information shown below has been mainly derived from recent Environment Agency (EA) reports, press articles, records in libraries, conversations with anglers and personal observations. A great source of historical information has been the Pollution Commission Report (Pollution Commission, 1867). A number of the paragraphs of this report are referred to in this article. Many stretches of the Aire are relatively inaccessible and remain seldom fished and little surveyed by the EA. This leads to information being biased towards other areas which can then result in omissions of some fish populations. However, it is hoped that the information given here will help to give a reasonable view of the position in 2013. The typical zonation of Yorkshire rivers, with trout in the higher reaches and Roach Rutilus rutilus in the lower reaches is disrupted in the Aire by the presence of thirty or so weirs. These have a big effect on the fish populations due to their pooling effect. The species of fish in the slow deep water above a weir may be completely different to those in the shallow fast water below it. Current Position As recently as 1974, Dr D J Shilcock, the then Fisheries Officer for the Yorkshire Water Authority, stated that the fishery on the Aire ended at Esholt (Bradford) and below that there were only sticklebacks (Shilcock, 1974). Since that time, particularly over the last twenty years, there has been a huge improvement in the water quality and there are now fish populations all the way down the river and in most of the tributary becks which flow into it. Investment in sewage treatment, work on combined sewer overflows, regulation of industrial discharges and the collapse of the textile and other polluting industries have all accounted for this improvement. Two major developments have recently taken place which will have great bearing on future fish populations. One of these is the upgrading of the sewage treatment works at Esholt, Bradford, and Knostrop, Leeds. This work was brought about by the European Freshwater Fish Directive and the primary purpose was to reduce ammonia levels in the effluent from the works. The £75 million scheme at Esholt was completed in late summer 2009 and the staged improvements at Knostrop shortly afterwards. The Naturalist 138 (2013) 163 The other major development is the Humber District Plan of the European Water Framework Directive (WFD), which was signed off by the Secretary of State for the Environment in December 2009. The WFD addresses many problems in Europe’s rivers. The EA’s commitments in the Humber District Plan include the removal of all artificial barriers to fish migration and the return to all the Humber Region rivers of self-sustaining spawning populations of migratory fish by 2021. Weirs, hydros and fish passes Although corn milling weirs have been present on the River Aire since Norman times, it was the Aire and Calder Navigation, founded in 1699, and the Industrial Revolution which followed it, that led to additional and better-maintained weirs being built.

  • Malhamdale and Southern/South Western Dales Fringes
    Malhamdale and Southern/South Western Dales Fringes + Physical Influences Malhamdale The landscape of Malhamdale is dominated by the influence of limestone, and includes some of the most spectacular examples of this type of scenery within the Yorkshire Dales National Park and within the United Kingdom as a whole. Great Scar limestone dominates the scenery around Malham, attaining a thickness of over 200m. It was formed in the Carboniferous period, some 330 million years ago, by the slow deposition of shell debris and chemical precipitates on the floor of a shallow tropical sea. The presence of faultlines creates dramatic variations in the scenery. South of Malham Tarn is the North Craven Fault, and Malham Cove and Gordale Scar, two miles to the south, were formed by the Mid Craven Fault. Easy erosion of the softer shale rocks to the south of the latter fault has created a sharp southern edge to the limestone plateau north of the fault. This step in the landscape was further developed by erosion during the various ice ages when glaciers flowing from the north deepened the basin where the tarn now stands and scoured the rock surface between the tarn and the village, leading later to the formation of limestone pavements. Glacial meltwater carved out the Watlowes dry valley above the cove. There are a number of theories as to the formation of the vertical wall of limestone that forms Malham Cove, whose origins appear to be in a combination of erosion by ice, water and underground water. It is thought that water pouring down the Watlowes valley would have cascaded over the cove and cut the waterfall back about 600 metres from the faultline, although this does not explain why the cove is wider than the valley above.

Esch, Ph.D., Advisor Michael V. K. Sukhdeo, Ph.D., Chair T. Michael Anderson, Ph.D. Herman E. Eure, Ph.D. Erik C. Johnson, Ph.D. Clifford W. Zeyl, Ph.D. ACKNOWLEDGEMENTS First and foremost, I would like to thank my PI, Dr. Gerald Esch, for all of the insight, all of the discussions, all of the critiques (not criticisms) of my works, and for the rides to campus when the North Carolina weather decided to drop rain on my stubborn head. The numerous lively debates, exchanges of ideas, voicing of opinions (whether solicited or not), and unerring support, even in the face of my somewhat atypical balance of service work and dissertation work, will not soon be forgotten. I would also like to acknowledge and thank the former Master, and now Doctor, Michael Zimmermann; friend, lab mate, and collecting trip shotgun rider extraordinaire. Although his need of SPF 100 sunscreen often put our collecting trips over budget, I could not have asked for a more enjoyable, easy-going, and hard-working person to spend nearly 2 months and 25,000 miles of fishing filled days and raccoon, gnat, and entrail-filled nights. You are a welcome camping guest any time, especially if you do as good of a job attracting scorpions and ants to yourself (and away from me) as you did on our trips.

Half a century ago, the state of Hawai’i introduced the Bluestripe Snapper, Lutjanus kasmira, to O’ahu for fisheries enhancement. Today, this species shares an intestinal nematode parasite, Spirocamallanus istiblenni, with native Hawaiian fishes, raising the possibility that the introduced fish carried a parasite that has since spread to naı¨ve local hosts. Here, we employ a multidisciplinary approach, combining molecular, historical, and ecological data to confirm the alien status of S.

  • The Phosphorus Content of Fluvial Sediment in Rural and Industrialized River Basins
    Water Research 36 (2002) 685–701 The phosphorus content of fluvial sediment in rural and industrialized river basins Philip N. Owens*, Desmond E. Walling Department of Geography, School of Geography & Archaeology, University of Exeter, Amory Building, Rennes Drive, Exeter, Devon EX4 4RJ, UK Received 3 August 2000; received in revised form18 April 2001; accepted 9 May 2001 Abstract The phosphorus content of fluvial sediment (suspended sediment and the o63 mmfraction of floodplain and channel bed sediment) has been examined in contrasting rural (moorland and agricultural) and industrialized catchments in Yorkshire, UK. The River Swale drains a rural catchment with no major urban and industrial areas, and the total phosphorus (TP) content of fluvial sediment is generally within the range 500–1500 mggÀ1. There is little evidence of any major downstream increase in TP content. In contrast, fluvial sediment from the industrialized catchments of the Rivers Aire and Calder exhibits both higher levels of TP content and marked downstream increases, with values of TP content ranging from o2000 mggÀ1 in headwater areas upstreamof the mainurban and industrial areas, to values >7000 mggÀ1 at downstreamsites. These elevated levels reflect P inputs frompoint sources, such as sewage treatment works (STWs) and combined sewer overflows. The influence of STWs is further demonstrated by the downstream increase in the inorganic P/organic P ratio from o2 in the headwaters to >4 in the lower reaches. Comparison of the P content of suspended sediment with that of the o63 mmfraction of potential source materialssuggests that topsoil from upland moorland/pasture and from cultivated areas, and channel bank material are likely to be the main sources of particulate P (PP) in the River Swale and in the headwaters of the Rivers Aire and Calder.

  • Summary of Cheshire Moths: 2008-2013
    CHESHIRE (VICE COUNTY 58) SUMMARY OF CHESHIRE MOTHS: 2008-2013 Authors: Steve H. Hind and Steve Holmes Date: December 2015 Summary of Cheshire Moths 2008-2013 Introduction With the absence of an annual moth report for six years and following publication of the 2014 report earlier this year, we have attempted to bring together some of the main changes to the counties moth populations since the last county report for 2007. Individual Micro-moth reports were published for 2008 and 2009 in the Journal of the Lancashire & Cheshire Entomological Society, Volumes 133 & 134, for Sessions 2009 & 2010 of the Annual Report & Proceedings but this is the first report to include the counties macro-moths for those years. Unfortunately, the amount of work required to produce a similar type of document to the 2014 report would have taken well over a year or more to complete and as such a more selective approach has been taken; this translates to producing an account for just those species that have either: been reported on very few occasions, or have undergone significant changes, either in terms of distribution or population Summary No fewer than seven new macro-moth and 23 micro-moth species appeared for the first time in Cheshire during the period covered by this publication; an astonishing number brought about by Moth recording continuing to increase during the period, especially of micro-moths. We received a record 8,200 records of micro-moths in 2008, yet this more than doubled to 17,700 in 2013. There are a number of references, particularly within the accounts relating to macro-moths, where mention is made of either: the nth Cheshire record, or only ‘n’ records this century, or only ‘n’ Cheshire records To clarify these comments, they all relate to known, submitted, validated records within the County database.
