What is the primary method for minimizing bias and wildlife radiotelemetry studies |
Radio mark a representative sample of individuals from target population |
|
|
Went triangulating moose locations what assumption would you be making if you thought your locations were accurate |
The moose did not move in between consecutive locations |
|
|
Define sightability |
The proportion of the actual population accounted during a study |
|
|
How is the true location of a GPS radio color approximated |
Intersections of the circles from multiple satellites approximate true location of the GPS collar |
|
|
If 1000 elk are counted during an aerial survey and site ability is .50 how many elk are in the true population |
2000 elk |
|
|
When is the index population abundance bias |
Wendy index is a non-consistent proportion of the true abundance |
|
|
Why does the Utah division of wildlife resources use a population model to estimate mule deer abundance |
Because it is not practical to estimate population size using counts |
|
|
Write down the expression for the basic population projection model we discussed in lab this expression has four components not including immigration and emigration |
NT +1 equals NT plus BT minus DT |
|
|
A key conflict resolution strategy is to establish common ground between stakeholders. What is one of the best methods for maintaining common ground among stakeholders |
Focus on practical problems that are of limited scope and scale |
|
|
Define habitat use and habitat selection |
Habitat use: resources that receive some investment by an animal Habitat selection: When resources are used disproportionately to their availability |
|
|
Identify and define the four orders of spatial scale that are used to measure wildlife habitat |
First order species range Second order we’re at select within a greater landscape to put its home range or territory Third order how an animal slacks habitats with an home range Fourth order how an animal slacks forging patches food items diet etc. within its home range |
|
|
If your research objective is to determine the spatial distribution of a particular wild mammals give two reasons why you might choose non-invasive techniques |
Elusive species are difficult to capture Live capture is time consuming expensive and dangerous Difficulty of live capture-year-olds small sample sizes Life capture can alter animal behavior |
|
|
Explain how Researchers use VHF radio telemetry to measure survival of individually known animals your answer should refer to the function of the transmitter receiver and antenna |
Each animal is tagged with a transmitter that emits on a different frequency for each animal the signal can be picked up by the receiver in the end Hannah when an animal goes in active or in mobile and mortality signal is sent through the transmitter at a different pulse rate to key in the observer that the animal may be dead observers must find the collar to verify death |
|
|
What is the definition of the acronym VHF as it applies to VHF radio telemetry |
Very high frequency |
|
|
Higher frequency VHF radio telemetry signals |
Emirate radio waves with shorter wavelengths and are more subject to attenuation and signal Reflectance |
