TIME BUDGETS OF WYOMING GROUND SQUIRRELS, SPERMOPHILUS ELEGANS David A. Zegers' .\bstract.— Time budget of free-living adult Spermophiltts elegans differed significantly from that of juveniles in the Front Range of the Rockies during 1974-1975. No differences were found between males and females. Hour of day. day since emergence, air temperature, cloud cover, and presence of predators all correlated with the frequency of various components of the time budget. Study of time budgets is important in com- binocular, and a 20X telescope to observe the prehending the roles of animals in ecosystems squirrels from a blind.

Introduction to Risk Assessments for Methods Used in Wildlife Damage Management
Human Health and Ecological Risk Assessment for the Use of Wildlife Damage Management Methods by USDA-APHIS-Wildlife Services Chapter I Introduction to Risk Assessments for Methods Used in Wildlife Damage Management MAY 2017 Introduction to Risk Assessments for Methods Used in Wildlife Damage Management EXECUTIVE SUMMARY The USDA-APHIS-Wildlife Services (WS) Program completed Risk Assessments for methods used in wildlife damage management in 1992 (USDA 1997). While those Risk Assessments are still valid, for the most part, the WS Program has expanded programs into different areas of wildlife management and wildlife damage management (WDM) such as work on airports, with feral swine and management of other invasive species, disease surveillance and control. Inherently, these programs have expanded the methods being used. Additionally, research has improved the effectiveness and selectiveness of methods being used and made new tools available. Thus, new methods and strategies will be analyzed in these risk assessments to cover the latest methods being used. The risk assements are being completed in Chapters and will be made available on a website, which can be regularly updated. Similar methods are combined into single risk assessments for efficiency; for example Chapter IV contains all foothold traps being used including standard foothold traps, pole traps, and foot cuffs. The Introduction to Risk Assessments is Chapter I and was completed to give an overall summary of the national WS Program. The methods being used and risks to target and nontarget species, people, pets, and the environment, and the issue of humanenss are discussed in this Chapter. From FY11 to FY15, WS had work tasks associated with 53 different methods being used. -

Bear Lake Whitefish Prosopium Abyssicola
Bear Lake Whitefish Prosopium abyssicola Actinopterygii — Salmoniformes — Salmonidae CONSERVATION STATUS / CLASSIFICATION Rangewide: Critically imperiled (G1) Statewide: Critically imperiled (S1) ESA: No status USFS: Region 1: No status; Region 4: No status BLM: Rangewide/Globally imperiled (Type 2) IDFG: Game fish BASIS FOR INCLUSION Endemic to Bear Lake. TAXONOMY The Bear Lake whitefish is 1 of 3 sympatric members of the genus Prosopium. No subspecies has been proposed. DISTRIBUTION AND ABUNDANCE This species is endemic to Bear Lake. POPULATION TREND Monitoring for >20 years indicates the population is stable (Nielson and Tolentino 2002). HABITAT AND ECOLOGY The Bear Lake whitefish typically occurs in the benthic zone at water depths greater than 40 m (130 ft). Spawning occurs in mid–February to mid–March in shallow, rocky areas. Ostracods comprise the majority of the diet, but other invertebrates found on the lake bottom may be consumed. ISSUES The lowering of lake levels due to natural events and anthropogenic actions could limit spawning and rearing habitat. Increasing human development around the lake could lead to lowering of water quality due to waste water discharges. Legal and illegal introductions of piscivorous fish could affect populations by increased predation rate. RECOMMENDED ACTIONS Continue programs that (1) monitor the population status and trend; (2) evaluate the relationship between water quality and level and fish populations; (3) stock sterile triploid lake trout; and (4) removal of illegally introduced non–native fish (e.g., walleye) in conjuction with adjacent states.

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. -
Version 2020-04-20 Bear Lake Whitefish (Prosopium Abyssicola
Version 2020-04-20 Bear Lake Whitefish (Prosopium abyssicola) Species Status Statement. Distribution Bear Lake whitefish is one of four fish species naturally found only in Bear Lake, which straddles the Utah-Idaho border. This species has also never been transplanted elsewhere, and occurs nowhere else in the world (Sigler and Sigler 1987). Table 1. Utah counties currently occupied by this species. Bear Lake Whitefish RICH Abundance and Trends Prior to 1999, there was simply no reliable method for fishery biologists to differentiate Bear Lake whitefish from Bonneville whitefish at lengths less than approximately 10 inches outside of their respective spawning seasons (Tolentino and Thompson 2004). Therefore, the Utah Division of Wildlife Resources (UDWR) monitored both species combined as the “whitefish complex”. In 1999, Ward (2001) along with UDWR biologists (Tolentino and Thompson 2004) finally described a reliable method to distinguish the two whitefish species in Bear Lake. From 1999-2018 the UDWR has monitored gill net catch rates and composition of Bonneville and Bear Lake whitefish separately (Tolentino 2007). The population of Bear Lake whitefish has appeared to remain stable from 1999-2017, comprising an average of 26% of the whitefish species caught in survey nets each year. Statement of Habitat Needs and Threats to the Species. Habitat Needs Bear Lake whitefish spend a majority of their life near the bottom of the lake’s deep waters. For most of each year, they live at depths ranging from 130 to 200 feet (Thompson 2003, Tolentino 2007). However, during the months of February and March the adult fish move into rocky, somewhat shallower areas (20-100 feet) to spawn (Tolentino and Albrecht 2007). -

Species Assessment for Round Whitefish
Species Status Assessment Class: Osteichthyes (bony fishes) Family: Salmonidae (trout and whitefish) Scientific Name: Prosopium cylindraceum Common Name: Round whitefish Species synopsis: The round whitefish occurs from Alaska in the northwest to Labrador and New England in the east. With the exception of Lake Erie, its distribution includes the Great Lakes. Round whitefish lives in lakes with a well oxygenated deep zone and is native to 7 of 18 watersheds in the Adirondack Mountains. It has also been known as non-native to the Oswegatchie watershed (previously stocked) with no records since 1955. Its distribution within its historic range has shrunk to 8 sites. A stocking program has established two more populations within its former range. It is extirpated from the Upper Hudson watershed. I. Status a. Current and Legal Protected Status i.

Coregonus Nigripinnis) in Northern Algonquin Provincial Park
HABITAT PREFERENCES AND FEEDING ECOLOGY OF BLACKFIN CISCO (COREGONUS NIGRIPINNIS) IN NORTHERN ALGONQUIN PROVINCIAL PARK A Thesis Submitted to the Committee on Graduate Studies in Partial Fulfillment of the Requirements for the Degree of Master of Science in the Faculty of Arts and Science Trent University Peterborough, Ontario, Canada © Copyright by Allan Henry Miller Bell 2017 Environmental and Life Sciences M.Sc. Graduate Program September 2017 ABSTRACT Depth Distribution and Feeding Structure Differentiation of Blackfin Cisco (Coregonus nigripinnis) In Northern Algonquin Provincial Park Allan Henry Miller Bell Blackfin Cisco (Coregonus nigripinnis), a deepwater cisco species once endemic to the Laurentian Great Lakes, was discovered in Algonquin Provincial Park in four lakes situated within a drainage outflow of glacial Lake Algonquin. Blackfin habitat preference was examined by analyzing which covariates best described their depth distribution using hurdle models in a multi-model approach. Although depth best described their distribution, the nearly isothermal hypolimnion in which Blackfin reside indicated a preference for cold-water habitat. Feeding structure differentiation separated Blackfin from other coregonines, with Blackfin possessing the most numerous (50-66) gill rakers, and, via allometric regression, the longest gill rakers and lower gill arches. Selection for feeding efficiency may be a result of Mysis diluviana affecting planktonic size structure in lakes containing Blackfin Cisco, an effect also discovered in Lake Whitefish (Coregonus clupeaformis). This thesis provides insight into the habitat preferences and feeding ecology of Blackfin and provides a basis for future study. Keywords: Blackfin Cisco, Lake Whitefish, coregonine, Mysis, habitat, feeding ecology, hurdle models, allometric regression, Algonquin Provincial Park ii ACKNOWLEDGEMENTS First and foremost I would like to thank my supervisor Dr. -
