Wildlife Flashcards
how wildlife research is usually conducted (what environment?)
free-living, in natural habitat (field studies)
what are captive studies
wild-caught animals kept in captive conditions (as close to habitat as possible)
prolonged time an animal is held in captivity can cause
rejection by original group (conspecifics), losing access to essential resources, compromise ability to fend or feed for itself
where animals in captive studies should be returned
exact point of capture
what are In silico techniques
what may they be used for as a wildlife replacement
computer simulation
pop. studies, animal movements, predicting disease spread
how to practice reduction while performing captive studies
trapping once and only using appropriate amount, minimum samples, avoid repeating studies, using specific baits or trapping at specific times (minimize non target capture),
why indirect handling is better than direct
less invasive and less stress for animal (but gives less data)
what is a hair snare
ball of barbed wire, animal reaches for treat, hair is caught in wire, sample removed for DNA
how mark-recapture/ capture-recapture is done
trap 15 small mammals, mark, return to wild
next day= trap, count marked v unmarked
what is the shake and bake method
capture animal, put in bag w florescent powder release, follow trail at night w blacklight
genus species of north american porcupine
and order
erethizon dorsatum
order= rodentia
average lifespan of porcupine in wild
5-7yr
porcupines are plantigrade meaning
walk on pads of feet
where on the porcupines body are the longest quills
rosette area (“danger zone”), on the rump
natural predator to porcupine
fishers (also mountain lions)
