Final Flashcards
What are some problems with predators?
1) reduce livestock production in some cases
2) prey on upland birds, deer and antelope fawns, and waterfowl
What are the benefits of predators?
1) Maintain healthy ecosystems
2) Control rodent population
3) Wildfire watchers
4) may reduce density of other predators
5) Maintenance of “natural” communities
What are the two approaches for estimating coyote abundance?
1) Density Estimates
2) Relative abundance indicies
What are the 3 different ways to get density estimates?
1) Aerial counts
2) Catch-mark-release
3) Spotlight counts
What are the 7 ways of getting relative abundance indices?
1) Scat deposition rates
2) Scent station visitation rates
3) Catch-per-unit effort
4) Elicited howling responses
5) Standardized track counts
6) Road-killed coyotes
7) Harvest questionnaires and bounty payments
What should you take note of to determine what kind of predator it was?
1) position of the carcass
2) Any drag trails
3) Blood on the ground or vegetation
4) If carcass has been covered by vegetation or soil
5) obvious wounds on head, neck, and shoulders
6) examine feeding pattern
7) if the neck is broken
8) where puncutures are found
What are some lethal options for controlling coyotes?
1) Leg hold traps
2) Snares
3) M-44 Device
4) Calling and Shooting
5) Hunting with dogs
6) Aerial Hunting
7) Livestock protection collars
What are some alternative methods of predator control?
1) livestock guarding animals
2) Repellents and frightening devices
3) Aversive conditioning
4) Livestock husbandry and management practices
5) Fencing
6) Immunocontraception
define depredation.
the act or an instance of destruction, plunder, or ravaging
Who is the best girlfriend in the world?
Casey!!!
What are potential solutions for preventing depredation?
1) Frightening Devices
2) Lethal Control
3) Fencing and Netting
4) Feeding deterrents
5) Commercially available feeding deterrents
6) Summary of Repellents
Why is genetic variation so important?
1) ability to adapt over generations to environmental change
2) greater opportunity for individuals to adapt within their lifetime
Define genes
segments of heredity material that are positioned on chromosomes
Define Chromosomes.
structures that carry genes and are found in the nuclei of cells
Define Structural genes
genes that encode Amino Acid sequences or the structure of proteins
Define Regulatory genes.
control the expression of the structural genes during development or among different tissues
define Diploid
have two complete sets of chromosomes, usually one from mom and one from dad
