Seasonal and Diel Movements and Habitat Use of Robust Redhorses in the Lower Savannah River. Georgia, and South Carolina
Transactions of the American FisheriesSociety 135:1145-1155, 2006 [Article] © Copyright by the American Fisheries Society 2006 DO: 10.1577/705-230.1 Seasonal and Diel Movements and Habitat Use of Robust Redhorses in the Lower Savannah River, Georgia and South Carolina TIMOTHY B. GRABOWSKI*I Department of Biological Sciences, Clemson University, Clemson, South Carolina,29634-0326, USA J. JEFFERY ISELY U.S. Geological Survey, South Carolina Cooperative Fish and Wildlife Research Unit, Clemson University, Clemson, South Carolina, 29634-0372, USA Abstract.-The robust redhorse Moxostonta robustum is a large riverine catostomid whose distribution is restricted to three Atlantic Slope drainages. Once presumed extinct, this species was rediscovered in 1991. Despite being the focus of conservation and recovery efforts, the robust redhorse's movements and habitat use are virtually unknown. We surgically implanted pulse-coded radio transmitters into 17 wild adults (460-690 mm total length) below the downstream-most dam on the Savannah River and into 2 fish above this dam. Individuals were located every 2 weeks from June 2002 to September 2003 and monthly thereafter to May 2005. Additionally, we located 5-10 individuals every 2 h over a 48-h period during each season. Study fish moved at least 24.7 ± 8.4 river kilometers (rkm; mean ± SE) per season. This movement was generally downstream except during spring. Some individuals moved downstream by as much as 195 rkm from their release sites. Seasonal migrations were correlated to seasonal changes in water temperature. Robust redhorses initiated spring upstream migrations when water temperature reached approximately 12'C. Our diel tracking suggests that robust redhorses occupy small reaches of river (- 1.0 rkm) and are mainly active diumally. -

MAPPING and CHARACTERIZING a RELICT LACUSTRINE DELTA in CENTRAL LOWER MICHIGAN by Christopher B. Connallon a THESIS Submitted T
MAPPING AND CHARACTERIZING A RELICT LACUSTRINE DELTA IN CENTRAL LOWER MICHIGAN By Christopher B. Connallon A THESIS Submitted to Michigan State University in partial fulfillment of the requirements for the degree of Geography – Master of Science 2015 ABSTRACT MAPPING AND CHARACTERIZING A RELICT LACUSTRINE DELTA IN CENTRAL LOWER MICHIGAN By Christopher B. Connallon This research focuses on, mapping and characterizing the Chippewa River delta - a sandy, relict delta of Glacial Lake Saginaw in central Lower Michigan. The delta was first identified in a GIS, using digital soil data, as the sandy soils of the delta stand in contrast to the loamier soils of the lake plain. I determined the textural properties of the delta sediment from 142 parent material samples at ≈1.5 m depth. The data were analyzed in a GIS to identify textural trends across the delta. Data from 3276 water well logs across the delta, and from 185 sites within two-storied soils on the delta margin, were used to estimate the thickness of delta sands and to refine the delta's boundary. The delta heads near Mount Pleasant, expanding east, onto the Lake Saginaw plain. It is ≈18 km wide and ≈38 km long and comprised almost entirely of sandy sediment. As expected, delta sands generally thin away from the head, where sediments are ≈4-7m thick. In the eastern, lower portion of the delta, sediments are considerably thinner (≈<1-2m). The texturally coarsest parts of the delta are generally coincident with former shorezones. The thick, upper delta portion is generally coincident with the relict shorelines of Lakes Saginaw and Arkona (≈17.1k to ≈ 16k years BP), whereas most of the thin, distal, lower delta is generally associated with Lake Warren (≈15k years BP). -
Spatial Criteria Used in IUCN Assessment Overestimate Area of Occupancy for Freshwater Taxa
Spatial Criteria Used in IUCN Assessment Overestimate Area of Occupancy for Freshwater Taxa By Jun Cheng A thesis submitted in conformity with the requirements for the degree of Masters of Science Ecology and Evolutionary Biology University of Toronto © Copyright Jun Cheng 2013 Spatial Criteria Used in IUCN Assessment Overestimate Area of Occupancy for Freshwater Taxa Jun Cheng Masters of Science Ecology and Evolutionary Biology University of Toronto 2013 Abstract Area of Occupancy (AO) is a frequently used indicator to assess and inform designation of conservation status to wildlife species by the International Union for Conservation of Nature (IUCN). The applicability of the current grid-based AO measurement on freshwater organisms has been questioned due to the restricted dimensionality of freshwater habitats. I investigated the extent to which AO influenced conservation status for freshwater taxa at a national level in Canada. I then used distribution data of 20 imperiled freshwater fish species of southwestern Ontario to (1) demonstrate biases produced by grid-based AO and (2) develop a biologically relevant AO index. My results showed grid-based AOs were sensitive to spatial scale, grid cell positioning, and number of records, and were subject to inconsistent decision making. Use of the biologically relevant AO changed conservation status for four freshwater fish species and may have important implications on the subsequent conservation practices. ii Acknowledgments I would like to thank many people who have supported and helped me with the production of this Master’s thesis. First is to my supervisor, Dr. Donald Jackson, who was the person that inspired me to study aquatic ecology and conservation biology in the first place, despite my background in environmental toxicology. -
Nipigon Bay Area of Concern Status of Beneficial Use Impairments September 2010
Nipigon Bay Area of Concern Status of Beneficial Use Impairments September 2010 Nipigon Bay is in the most northerly area of Lake Superior. The Area of Concern takes in a large portion of Nipigon Bay and the Nipigon River, the largest tributary to Lake Superior, and the communities of Red Rock and Nipigon. There are Ontario Power Generation dams on the Nipigon River for the generation of hydroelectricity. The area supports a variety of wetlands and bird populations, including one of four known pelican colonies in Ontario. The watershed forests on both sides of the Nipigon River have been allocated for forest harvesting. Environmental concerns in the Nipigon Bay Area of Concern are related to water level and flow fluctuations in Lake Nipigon and the Nipigon River from the generation of hydroelectricity. These fluctuations affect stream bank stability, sediment load and fish and wildlife habitat. Other concerns include the accumulation of wood fibre, bark and other organic material from past log drives, and effluent discharges from a linerboard mill (which closed in 2006) and the municipal sewage treatment plants in Nipigon and Red Rock. PARTNERSHIPS IN ENVIRONMENTAL PROTECTION Nipigon Bay was designated an Area of Concern in 1987 under the Canada–United States Great Lakes Water Quality Agreement. Areas of Concern are sites on the Great Lakes system where environmental quality is significantly degraded and beneficial uses are impaired. Currently, there are 9 such designated areas on the Canadian side of the Great Lakes, 25 in the United States, and 5 that are shared by both countries. In each Area of Concern, government, community and industry partners are undertaking a coordinated effort to restore environmental quality and beneficial uses through a remedial action plan. -

Great Lakes Region, USA
Spatial variation in till texture and clay mineralogy across the Saginaw Lobe terrain, Great Lakes region, USA Department of Geography, Environment and Spatial Sciences, Randall J. Schaetzl, Chris Baish, Jarrod Knauff, Thomas Bilintoh, East Lansing, Michigan, USA Dan Wanyama, Kevin McKeehan, and Michelle Church Abstract STUDY AREA SAMPLE DISTRIBUTION Great Lakes region We present a spatial/mapping approach to the study of the glacial history of the Saginaw lobe of the Laurentide Ice Sheet. The Saginaw Lobe flowed into southern Michigan, USA, forming modern-day Saginaw Bay and leaving behind a series of small moraines in down- ice locations. Upon its retreat – and likely also during its advance – a large proglacial lake (Glacial Lake Saginaw) formed in the northeastern margins of the “Saginaw terrain”. The Saginaw lobe advanced to the southwest, out of this lake basin and onto thinly mantled, sandstone and shale bedrock. Although the Late Pleistocene deglacial chronology of this lobe has been generally assumed for decades, few numerical ages exist that could help constrain a better defined timeline. Indeed, as luminescence ages slowly emerge for terrain of the Saginaw Lobe and nearby areas, it seems clear that the lobe retreated from the region considerably earlier than is generally assumed, adding to the potential for large areas of ponded water in proglacial settings, all of which are as yet unmapped. In this project, we sampled tills on uplands across the terrain of the Saginaw Lobe, avoiding outwash plains. In all, we obtained 334 samples of calcareous till, by bucket auger. Sample locations were sited generally uniformly across >20,000 km2. -
The State of Lake Huron in 2010 Special Publication 13-01
THE STATE OF LAKE HURON IN 2010 SPECIAL PUBLICATION 13-01 The Great Lakes Fishery Commission was established by the Convention on Great Lakes Fisheries between Canada and the United States, which was ratified on October 11, 1955. It was organized in April 1956 and assumed its duties as set forth in the Convention on July 1, 1956. The Commission has two major responsibilities: first, develop coordinated programs of research in the Great Lakes, and, on the basis of the findings, recommend measures which will permit the maximum sustained productivity of stocks of fish of common concern; second, formulate and implement a program to eradicate or minimize sea lamprey populations in the Great Lakes. The Commission is also required to publish or authorize the publication of scientific or other information obtained in the performance of its duties. In fulfillment of this requirement the Commission publishes the Technical Report Series, intended for peer-reviewed scientific literature; Special Publications, designed primarily for dissemination of reports produced by working committees of the Commission; and other (non-serial) publications. Technical Reports are most suitable for either interdisciplinary review and synthesis papers of general interest to Great Lakes fisheries researchers, managers, and administrators, or more narrowly focused material with special relevance to a single but important aspect of the Commission's program. Special Publications, being working documents, may evolve with the findings of and charges to a particular committee. Both publications follow the style of the Canadian Journal of Fisheries and Aquatic Sciences. Sponsorship of Technical Reports or Special Publications does not necessarily imply that the findings or conclusions contained therein are endorsed by the Commission. -

MAGYAR NYELVŐR 142. ÉVF. * 2018. ÁPRILIS–JÚNIUS * 2. SZÁM Dayka Gábornak Aorthographia címet kapott, kéziratban fennmaradt magyar nyelvű, nyelvészeti jellegű írásáról 1. Bevezetés. A tervem az, hogy a nyelvtudomány-történet keretében bemutas- sam a mindössze huszonnyolc évet élt, sajátos hangú 18. századi költőnek, Dayka Gábornak a kéziratban fennmaradt nyelvtani, egyáltalán nyelvészeti irányultsá- gú munkáit. A sorrendet illetően a Dayka-kutatáshoz alapot nyújtó Dayka Gábor Összes Művei című kötetet követem (az adatait l. DGÖM). Ez a kötet egyébként tartalmazza Dayka Gábornak – költői és prózai alkotásain kívül – a következő nyelvtani, nyelvészeti jellegű írásait: „Grammatikák és grammatikai jegyzetek: 1. Magyar nyelvű grammatikai tárgyú írások: a) Aorthographia és b) Grammati- kai feljegyzések. – 2. Proludium in Institutiones Linguae Hungaricae. – 3. Ternio Grammaticae Hungaricae 1794” (DGÖM 7). Meg kell jegyeznem, hogy bár e munkáknak se a pontos keletkezési idejét, se egymás utáni következésük sor- rendjét nem lehetett bizonyítottan megállapítani, a DGÖM-ben alkalmazott és idézett sorrend látszik logikusnak és követendőnek. A kötet tartalmazza az ere- deti szövegeken kívül – ha idegen nyelvűek – azok fordítását is, továbbá minden szöveg után a széles körű rálátással megírt jegyzeteket, amelyek megemlékeztek a kéziratról, az illető szöveg megjelenéséről, valamint közölnek szövegkritikát, és „Magyarázatok” címen tárgyalják az illető mű keletkezés- és fogadástörténetét, valamint közölnek számos fogalmat, jelenséget megvilágító megjegyzést. Egyéb- ként a filológusi feldolgozást a lehetséges teljességre, a rendszerességre, a minden lényeges kérdésnek az utánajárására, a logikus felépítésre, a pontosságra, valamint a világos megfogalmazásra való törekvés jellemzi (l. részletesen: DGÖM 64–9). Elöljáróban még szólok több éve tartó Dayka-kutatásaim első eredményé- ről, a Mi vitte Dayka Gábort, a költőt a nyelvtanírás, egyáltalán a nyelvtudomány felé? című tanulmányról (Szathmári 2016).
