Hunting: Consumption
Definition
People hunt as a source of food either recreational or as a necessity. But also for clothing for fashion or again necessity.
Term
Hunting: Economics
Definition
Individual sale for one person to make a living, but also to protect livestock/control pests that cost money.
Term
Hunting: Recreation/Social
Definition
People enjoy hunting for sport and as a hobby. People bond over it and for communities around it.
Term
Hunting: Ecological Management
Definition
Hunting a tool to combat overpopulation. Also hunt predators of endangered species.
Term
Hunting: Financial/Political
Definition
Money to be made off hunting privately, but also good for government to work with hunters to make money to supply management funds through permits.
Term
Hunting Controversies
Definition
Unnecessary, guns involved, inhumane methods, prideful, morally wrong, not experienced by most of population.
Term
Hunting Management
Definition
Biological: Monitor populations and sustainability.
Socially: Law enforcement, open discussion, get money, include differing values.
Term
Exotic Species

Convention on International Trade in Endangered Species
Definition
Known as CITES, a voluntary agreement among nations regulating the harvest and trade of endangered species. Consists of three Appendices classifying species trade allowances.
Term
CITES Appendix I
Definition
Highest regulation. Endangered no matter what country. Permits needed for import/export and no commercial sale allowed.
Term
CITES Appendix II
Definition
Species considered threatened in all countries. Need permit to export, sale possible.
Term
CITES Appendix III
Definition
Least regulated, considered threatened by exporting country and exporting country regulates those exports.
Term
Delisting Species Process
Definition
Must have scientific evidence species can withstand exploitation. Have well-documented population trends showing this. Produce comprehensive trade analysis showing sustainability.
Term
Blanket-Listing
Definition
Practice of listing all species closely related to the actually endangered one. Protects against difficulties distinguishing endangered from not endangered and dominoes effect of poaching species that look like endangereds.
Term
CITES Flaws
Definition
• Enforcement is not strong enough.
• Not all nations recognize regulations.
• Appendix II usually pushed though.
• Trade still occurs.
• Conflicts between countries and what should be regulated.

Term
Park Priorities
Definition
Diversity, distinctiveness, prevent species endangerment, and utility by locals/wildlife/researchers.

The bugger the park, the less there are of that size. Unless it's less than 10 Sq km. Most in 10-29 sq km range.
Term
Gap Analysis

Layering different mapping (vegetation, developments, political lines, etc) to identify potential protection areas.
Term
Designing Protected Areas
Definition
Size, configuration (divided, linear vs round, close vs far, etc.), and shape.
Term
Biosphere Reserves
Definition
Part of UNESCO, effort to save all habitat, plant, and animal types from extinction. Representativeness more important than uniqueness.

Few endangered species in zoos, depend directly on money (upkeep, facilities, conservation actions), limited space, genetics.
Term
Zoo Genetics Problems
Definition
Founder effects of small populations, must have detailed breeding plan, age and sex compositions need adjusting, must simulate genetic selection, and teach skills for releasing to wild.
Term

Single species approach is standard through captive propagation.
Ecosystem approach manages whole reserve they inhabit.
Umbrella species uses one species to justify indirectly protect others around it.
Term
Tale of Black-Footed Ferrets
Definition
Preyed of prairie dogs, mass prairie dog kill in 1800s, ferrets thought extinct, till some found in the 80s, then they had diseases, management ensued, trying to reintroduce more from captivity.
Term
Climate Change Primary Effects
Definition
Stranding populations, life-stage habitat loss, altered biological events from temp changes.
Term
Climate Change Secondary Effects
Definition
Increased stress, disrupted predator-prey dynamics, opportunistic invasives more successful.
Term
Humans and Climate Change
Definition
Habitat conversion for us, increased pollution and land use, induced invasives movement.
Term
Peary Caribou and Climate Change
Definition
Habitat shifts north and longer growing thawed season for food. BUT more snow likely which means harsher snow cover of food over winter meaning less for to survive.
Term
Conservation by Consumption
Definition
Regulated hunting in concert with restoration efforts that was very successful in North america.
Term
Economic Impact of US Hunters
Definition
They spent $24.7 billion which results in a positive impact by $66.7 billion and supports almost 660,000 jobs.
Term
Public Relations in Hunting
Definition
Public needs to know not all hunting bad. It's a necessary part of keeping populations controlled, people interested, and making money.
Term
Turkey Nest Depredation
Definition
Wet weather creates humid, breezy, temp inversion by ground creates ideal olfaction conditions which increases success amongst turkey prey.
Term
Trophic Mismatch
Definition
When food availability and habitat resources are no longer in sync with when wildlife need them. Birds that are vital prey migrate too early or too late to be food for some dependent species.
Term
Accidental Bird Death
Definition
In the billions and most caused by crashing into windows. More killed accidentally thanot hunted by man.
Term
Abiotic Filters in Restoration
Definition
Climate (rainfall, temps), substrate (toxicity, soil water), and landscape (patch size, previous use, isolation, etc.)
Term
Museum Records and Restoration
Definition
Natural history collections show historic ranges and genetic sampling but degree of ignorance in early studies must be accounted for.
Term
Stepping-Stone Corridors
Definition
When full corridors not needed/possible, small patches of resting areas lead to another large habitat.
Term
Main GHGs
Definition
Greenhouse gasses, most common are carbon dioxide, methane, nitrous oxide, and halocarbons. These have biggest impact on climate change.
Term
Climate Change and Bird Migration
Definition
Shifts in arrival dates for breeding may occur, shortening distances and some will shift around. Longer migrations cued by photo period changes may not know to shift and will perish.
Term
Climate Change and Range Shifts
Definition
Species will move their distributions if they can or die. Changes in community composition imminent.
Term
Bioclimatic Envelope Modeling
Definition
Attempt to define climatic conditions that best describe species range limits and then shows how they'll react to changing climate.
Term
Nonessential Experimental Population
Definition
A compromise to address local concerns about wolf reintroduction to Yellowstone, title permitted landowners to kill wolves seen eating livestock, but still protected eslewhere.
