Boiga Irregularis+ (Reptile) Aug 2006

Boiga Irregularis+ (Reptile)

Other Publications in Wildlife Management

This night-loving and tree-loving, brown tree snake (Boiga irregularis) is so secretive in its nature that it is frequently concealed on container ships and in aircraft cargo. It probably arrived on Guam after World War II in a cargo ship. Now the wetlands, coastlands and forests of Guam are bereft of nine out of twelve native bird species (and two out of eleven native lizards) due to the snakes voracious appetite. The brown tree snake is not a fussy feeder, stimulating the very real fear that it might drive yet more species to extinction.


Sus Scrofa (Mammal) Aug 2006

Sus Scrofa (Mammal)

Other Publications in Wildlife Management

Pigs are large omnivorous mammals with powerful bodies and coarse hairy coats. Their thick necks, wedge-shaped heads and mobile snouts are used in feeding to uproot the ground and find prey or plant material. Ecological characteristics of feral pig activity, group size and home range size should be considered in any management strategy aimed to control pig numbers or reduce their negative impact. Feral pig activity varies between different habitats and climates. High activity has been reported to occur in early morning and late afternoon in tropical climates (Diong 1982). However, in India pigs have been reported to feed nocturnally ...

Bufo Marinus (Amphibian)

Other Publications in Wildlife Management

B. marinus is a heavily built toad with short legs. It can grow upto 15 cm long sometimes. Fingers lack webbing, but the toes are heavily webbed. Adults have a rough, warty skin, colored tan, brown or dark brown, dull green or black. The tympanum is distinct, about one half to two thirds the size of the eye. Venom glands are widely distributed around the surface of the skin, but can also be aggregated together to form large parotoid glands, found on each shoulder. these glands are able to ooze venom. (Gautherot, 2000) Eggs are laid in long strands. Tadpoles ...


Disease Emergence And Resurgence: The Wildlife-Human Connection, Milton Friend May 2006

Disease Emergence And Resurgence: The Wildlife-Human Connection, Milton Friend

Other Publications in Wildlife Management

Humans have been affected by and have contributed to the eruption and spread of disease since antiquity. This connectivity is such that disease in the Americas was one of the five Seeds of Change addressed by the National Museum of Natural History’s commemoration of the Columbus Quincentenary. As for the other Seeds of Change, diseases “…sent ripples around the globe, affecting the people as well as the flora and fauna of both the New World and the Old.” During recent decades, these ripples have become waves that are likely to intensify, swelled by human population growth, civil strife, and ...


Public Health Confronts The Chicken, The Hamster, And The Goat, W. John Pape May 2006

Public Health Confronts The Chicken, The Hamster, And The Goat, W. John Pape

Other Publications in Wildlife Management

John Pape is an Epidemiologist with the Communicable Disease Epidemiology Program, Colorado Department of Public Health & Environment. This slide-show presents facts and images relating to Zoonoses: diseases of animals transmissible to humans under natural conditions. The characteristics of Zoonoses are: common in natural reservoir, uncommon in people; rural exposure; serious diseases with high fatality rates; complex cycles; prevention achieved via “The Weakest Link.” Zoonotic diseases comprise the majority of potential bioterrorist agents and emerging infections.

Specific sections include:
Influenza, Avian Influenza,and Pandemic Influenza
Projected Pandemic Scenarios COLORADO
H5N1 Surveillance Strategy in US
Baylisascaris and Racoons
Q-fever Outbreak Associated with Goats
Hamsters & Tularemia
Sin Nombre Virus in Colorado: Deer Mice and Cotton Rats

Identification Of Turkey Breast Bones, David Oates May 2006

Identification Of Turkey Breast Bones, David Oates

Other Publications in Wildlife Management

Height and shape of keel differ in domestic and wild turkeys. Wild birds typically have a dip in the keel and no drastic slope change after the dip. The distance from the lip on the upper edge of the sternum to the tip of the cranial end of the keel is obviously greater in wild than domestic birds. Note that not only the distance between the arrows differs in the figure above, but also the curvature of the slope. Breadth of the keel is greater on domestic birds, but the height of the keel is greater on wild toms. The ...


Impacts Of Feral And Free-Ranging Cats On Bird Species Of Conservation Concern, Linda Winter, George E. Wallace Ph.D. May 2006

Impacts Of Feral And Free-Ranging Cats On Bird Species Of Conservation Concern, Linda Winter, George E. Wallace Ph.D.

Other Publications in Wildlife Management

This report reviews cat predation impacts on rare birds in the states of New York, New Jersey, Flor¬ida, California, and Hawaii, reviews government-authorized programs and ordinances affecting feral and free-ranging cats and their management, and makes recommendations on better ways to manage cat overpopulation problems. Sites marked * are State Important Bird Areas (IBAs) and sites marked ** are Global IBAs as identified by American Bird Conservancy (ABC) in The American Bird Conservancy Guide to the 500 Most Important Bird Areas in The United States. These areas are considered high priorities for cat control to protect threatened bird species.


Invasive Species Definition Clarification And Guidance White Paper Apr 2006

Invasive Species Definition Clarification And Guidance White Paper

Other Publications in Wildlife Management

An invasive species is a non-native species whose introduction does or is likely to cause economic or environmental harm or harm to human, animal, or plant health. The National Invasive Species Management Plan indicates that NISC will focus on non-native organisms known to cause or likely to cause negative impacts and that do not provide an equivalent or greater benefit to society. In the technical sense, the term ‘invasion’ simply denotes the uncontrolled or unintended spread of an organism outside its native range with no specific reference about the environmental or economic consequences of such spread or their relationships to ...


Feral Pigs In Queensland - Distribution, Ecology And Impact Feb 2006

Feral Pigs In Queensland - Distribution, Ecology And Impact

Other Publications in Wildlife Management

Domestic pigs (Sus scrofa) were introduced to Australia by early settlers. Subsequent accidental and deliberate releases resulted in the wild (feral) population establishing throughout Australia. Feral pigs damage crops, stock and property, spread weeds and transmit diseases such as Leptospirosis and Foot and Mouth. They also cause environmental damage, digging up large areas of native vegetation and spreading weeds.

Feral pigs are declared Class 2 pests under Land Protection (Pest and Stock Route Management) Act 2002. Declaration requires landholders to control declared pest on the land under their control. A local government may serve a notice upon a landholder requiring ...

Bat House Construction And Installation, Stephen Vantassel, Scott E. Hygnstrom, Ron J. Johnson, Dennis Ferraro

Other Publications in Wildlife Management

Bat house construction and installation can be an environmentally friendly and rewarding activity. Putting up a bat house, however, does not guarantee that bats will use it. We don't know exactly why bats dwell in one house and not another, but by following a few recommendations you can increase the likelihood that bats will live in your bat house.

Some bats live in colonies that include tens of thousands of individuals. In Nebraska, the big brown bat (Eptesicus fuscus) and little brown bat (Myotis lucifugus) live in colonies of 10 to 200 and are the most likely candidates to ...

Mule Deer, Western Association Of Fish And Wildlife Agencies Mule Deer Working Grop

Other Publications in Wildlife Management

Since 1922, the Western Association of Fish and Wildlife Agencies (WAFWA) has served as a leader promoting management and protection of fish and wildlife in the western United States and Canada. An organization represented by 17 states and four Canadian provinces, WAFWA has faced the difficult challenge of sifting through the ever-changing societal, economic, political and scientific issues that define natural resource management in a West that has undergone many changes.

WAFWA is particularly concerned about mule deer, a species that lives in every North American habitat except for the tropics, arctic and extreme deserts. Mule deer numbers and distribution ...
