  • 10 896 Zanatta 6.Indd
    2011 NORTHEASTERN NATURALIST 18(1):1–6 Confi rmation of Obovaria olivaria, Hickorynut Mussel (Bivalvia: Unionidae), in the Mississagi River, Ontario, Canada David T. Zanatta1,* and Daelyn A. Woolnough1 Abstract - A signifi cant and recruiting population of Obovaria olivaria (Hickorynut Mussel) was confi rmed in the Mississagi River, Lake Huron drainage, ON, Canada. This large river unionid mussel is known to use Acipenser fulvescens (Lake Sturgeon) and Scaphirhynchus platorynchus (Shovelnose Sturgeon) as hosts. The Mississagi River is known to have a spawning Lake Sturgeon population. In 9.1 person-hours of snorkel and SCUBA searches, 10 live O. olivaria ranging in length from 36 to 79 mm, including six gravid females, were collected in sandy substrates with water depths from 1.5 to 4 m. Obovaria olivaria in the Mississagi River represent a signifi cant range disjunction from the other extant populations in Canada in the Ottawa and St. Lawrence river drainages. As the conservation status of this rare mussel in Canada is assessed, the geographic genetic population structure and spatial extent among known areas should be studied to under- stand the post-glacial redistribution of the species. Introduction Obovaria olivaria (Rafi nesque) (Hickorynut Mussel), is a deepwater, large river unionid that can be abundant in the Mississippi basin of central North Amer- ica (Parmalee and Bogan 1998, Williams et al. 2008). In contrast, O. olivaria is a rare mussel in the St. Lawrence River and Great Lakes watershed of central North America (Clarke 1981, Metcalfe-Smith et al. 2005, NatureServe 2009) and is cur- rently under assessment by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC).

  • An Assessment of the Groundwater Resources of Northern Ontario
    Hydrogeology of Ontario Series (Report 2) AN ASSESSMENT OF THE GROUNDWATER RESOURCES OF NORTHERN ONTARIO AREAS DRAINING INTO HUDSON BAY, JAMES BAY AND UPPER OTTAWA RIVER BY S. N. SINGER AND C. K. CHENG ENVIRONMENTAL MONITORING AND REPORTING BRANCH MINISTRY OF THE ENVIRONMENT TORONTO ONTARIO 2002 KK PREFACE This report provides a regional assessment of the groundwater resources of areas draining into Hudson Bay, James Bay, and the Upper Ottawa River in northern Ontario in terms of the geologic conditions under which the groundwater flow systems operate. A hydrologic budget approach was used to assess precipitation, streamflow, baseflow, and potential and actual evapotranspiration in seven major basins in the study area on a monthly, annual and long-term basis. The report is intended to provide basic information that can be used for the wise management of the groundwater resources in the study area. Toronto, July 2002.

Alternatively, the Center requests that the USFWS define and list distinct population segments of lake sturgeon in the U.S. as threatened or endangered. Lake sturgeon populations in Minnesota, Lake Superior, Missouri River, Ohio River, Arkansas-White River and lower Mississippi River may warrant endangered status. Lake sturgeon populations in Lake Michigan and the upper Mississippi River basin may warrant threatened status. Lake sturgeon in the central and eastern Great Lakes (Lake Huron, Lake Erie, Lake Ontario and the St. Lawrence River basin) seem to be part of a larger population that is more widespread.

    Biological Services Program FWS/OBS-82/52 SEPTEMBER 1982 ATLAS OF THE SPAWNING AND NURSERY AREAS OF GREAT LAKES FISHES Volume II - Lake Superior Great Lake - St. Lawrence Seaway Navigation Season Extension Program Fish and Wildlife Service Corps of Engineers U.S. Department of the Interior U.S. Department of the Army The Biological Services Program was established within the U.S. Fish and Wildlife Service to supply scientific information and methodologies on key environmental issues that Impact fish and wildlife resources and their supporting ecosystems. The mission of the program is as follows: o To strengthen the Fish and Wildlife Service in its role as a primary source of information on national fish and wild- life resources, particularly in respect to environmental impact assessment. o To gather, analyze, and present information that will aid decisionmakers in the identification and resolution of problems associated with major changes in land and water use. o To provide better ecological information and evaluation for Department of the Interior development programs, such as those relatfng to energy development. Information developed by the Biological Services Program is intended for use in the planning and decisionmaking process to prevent or minimize the impact of development on fish and wildlife. Research activities and technlcal assistance services are based on an analysis of the issues, a determination of the decisionmakers involved and their informatlon needs, and an evaluation of the state of the art to identify information gaps and to determine priorities. This is a strategy that will ensure that the products produced and disseminated are timely and useful.

  • The Expansion of Ojibway and French Place ÂŒ Names Into the Lake
    The Expansion of Ojibway and French Place-names into the Lake Superior Region in the Seventeenth Century! ALAN H. HARTLEY DESPITE ITS LOCATION in the remote interior of North Amer- ica, Lake Superior has a written history of almost 350 years. It owes its early exploration and settlement to its position on the ancient trans- continental water-route which extends from the Gulf of S1. Lawrence, through the Ottawa River, Lake Winnipeg and the Saskatchewan River, to the Rocky Mountains. It was the westward expansion of Ojibway-speaking Indians2 and the French, their customers in the fur trade, which made this vast area known to Europe. The early to- ponymy of Lake Superior and its eastern approaches reflects this partnership in its mixture of Ojibway and French names. For the purposes of this study, the westward expansion of the French can be considered to have occurred in three stages. I. 1608-1641, from Samuel de Champlain's establishment of a trading post at Quebec, through Jean Nicolet's explorations around Green Bay in 1634, to the visit of Fathers Jogues and Raymbault to Sault Ste. Marie. Lake Superior lay in unexplored country. II. 1659-1684, from Radisson and Des Groseillers' explorations in western Lake Superior and the Sioux country, to Sieur Dulhut's establishment of posts on Lake Nipigon, Thunder Bay and possibly the headwaters of the St. Croix River in Wisconsin. This was the period during which the Lake Superior basin 1 I am grateful to the following for their constructive reviews of this paper: Alan Rayburn, Secretariat of Geographical Names, Ottawa; William Cowan, Carleton University, Ottawa; Edith Hols, University of Minnesota, Duluth; Donald Lawrence, University of Minnesota, Minneapolis.
