  • Wild Species 2010 the GENERAL STATUS of SPECIES in CANADA
    Wild Species 2010 THE GENERAL STATUS OF SPECIES IN CANADA Canadian Endangered Species Conservation Council National General Status Working Group This report is a product from the collaboration of all provincial and territorial governments in Canada, and of the federal government. Canadian Endangered Species Conservation Council (CESCC). 2011. Wild Species 2010: The General Status of Species in Canada. National General Status Working Group: 302 pp. Available in French under title: Espèces sauvages 2010: La situation générale des espèces au Canada. ii Abstract Wild Species 2010 is the third report of the series after 2000 and 2005. The aim of the Wild Species series is to provide an overview on which species occur in Canada, in which provinces, territories or ocean regions they occur, and what is their status. Each species assessed in this report received a rank among the following categories: Extinct (0.2), Extirpated (0.1), At Risk (1), May Be At Risk (2), Sensitive (3), Secure (4), Undetermined (5), Not Assessed (6), Exotic (7) or Accidental (8). In the 2010 report, 11 950 species were assessed. Many taxonomic groups that were first assessed in the previous Wild Species reports were reassessed, such as vascular plants, freshwater mussels, odonates, butterflies, crayfishes, amphibians, reptiles, birds and mammals. Other taxonomic groups are assessed for the first time in the Wild Species 2010 report, namely lichens, mosses, spiders, predaceous diving beetles, ground beetles (including the reassessment of tiger beetles), lady beetles, bumblebees, black flies, horse flies, mosquitoes, and some selected macromoths. The overall results of this report show that the majority of Canada’s wild species are ranked Secure.

Like mosquitoes, it is the female fly that is responsible for inflicting a bite. The males are mainly pollen Description and nectar feeders. Tabanids are most likely encountered in hot summer and early fall weather. They are active during Eggs daylight hours. Eggs are laid in masses ranging from 100 to 1000 eggs. Eggs are laid in layers on a vertical surface, such as overhanging foliage, projecting rocks, sticks, and aquatic vegetation. Aquatic vegetation is preferred. A shiny or chalky secre- tion, which aids in water protection, often covers eggs. The vertical surfaces on which the eggs are deposited are always directly over water and wet ground favorable to the development of larvae. The female will not deposit egg masses on vegetation that is too dense.

Maine lies astride the 45th parallel and is the eastern most point of land in the continental United States. It is largely rural, heavily forested, and it encompasses innumerable lakes, ponds, streams and bogs. Roughly 90% of the land mass is forested and of this portion 45-50% is of the spruce-fir type. Northern hardwoods (beech, birch and maple) dominate the ridges and much of the upland and make up the second most common forest type. Pines and other species are scattered throughout. Settlers and colonists have been involved in the advance and retreat of open and developed land for hundreds of years and have introduced various plants and animals in the course of their activi­ ties.

Lazăr1, O.C. Iacob1*, C. Solcan1, S.A. Pașca1, R. Lazăr2, P.C. Boișteanu2 "Ion Ionescu de la Brad' University of Agricultural Sciences and Veterinary Medicine, Iasi, Alley M. Sadoveanu 3, 700490, Iași ABSTRACT Investigations of four roe deer corpses were carried out from May until October 2014, in the Veterinary Forensic Laboratory and in the Parasitic Diseases Clinic, in the Iasi Faculty of Veterinary Medicine. The roe deer were harvested by shooting during the trophy hunting season. The clinical examination of the shot specimens revealed the presence of a highly consistent number of extremely mobile apterous insects, spread on the face, head, neck, lateral body parts, abdominal regions, inguinal, perianal and, finally, all over the body. The corpses presented weakening, anemia and cutaneous modification conditions. Several dozen insects were prelevated in a glass recipient and preserved in 70º alcoholic solution in order to identify the ectoparasite species. The morphological characteristics included insects in the Diptera order, Hippoboscidae family, Lipoptena cervi species. These are highly hematophagous insects that by severe weakening are affecting the game health and trophy quality. Histological investigations of the skin revealed some inflammatory reactions caused by ectoparasite Lipoptena cervi. Lipoptena cervi was identified for the first time in Iasi County, Romania.

Some species develop in the soil in salt marshes, brackish pools and tidal over wash areas. A few species are found along beaches and seem to be associated with vegetative debris accumulating there. The majority of the tabanid species, however, develop in a variety of upland situations ranging from very wet to semi-dry (tree holes, rotting logs, margins of ponds, streams, swamps and drainage ditches).

  • BMBL) Quickly Became the Cornerstone of Biosafety Practice and Policy in the United States Upon First Publication in 1984
    Biosafety in Microbiological and Biomedical Laboratories 5th Edition U.S. Department of Health and Human Services Public Health Service Centers for Disease Control and Prevention National Institutes of Health HHS Publication No. (CDC) 21-1112 Revised December 2009 Foreword Biosafety in Microbiological and Biomedical Laboratories (BMBL) quickly became the cornerstone of biosafety practice and policy in the United States upon first publication in 1984. Historically, the information in this publication has been advisory is nature even though legislation and regulation, in some circumstances, have overtaken it and made compliance with the guidance provided mandatory. We wish to emphasize that the 5th edition of the BMBL remains an advisory document recommending best practices for the safe conduct of work in biomedical and clinical laboratories from a biosafety perspective, and is not intended as a regulatory document though we recognize that it will be used that way by some. This edition of the BMBL includes additional sections, expanded sections on the principles and practices of biosafety and risk assessment; and revised agent summary statements and appendices. We worked to harmonize the recommendations included in this edition with guidance issued and regulations promulgated by other federal agencies. Wherever possible, we clarified both the language and intent of the information provided. The events of September 11, 2001, and the anthrax attacks in October of that year re-shaped and changed, forever, the way we manage and conduct work

Chrysops Common name: deer flies, yellow flies and horse flies Scientific name: Chrysops, Diachlorus, and Tabanus spp. (Insecta: Diptera: Tabanidae) Introduction The family Tabanidae, commonly known as horse flies, and deer flies, contains pests of cattle, horses and humans. In Florida there are 35 species of Tabanidae that are considered economically important. Horse flies are in the genus Tabanus and deer flies are in the genus Chrysops. The yellow fly, Diachlorus ferrugatus (Fabricius), is known in Florida as a fierce biter. Like mosquitoes, it is the female fly that is responsible for inflicting a bite. The males are mainly pollen and nectar feeders. Tabanids are most likely encountered in hot summer and early fall weather. They are active during daylight hours. Figure 1.
