wildlife ecology (class 4 material)

telemetry

how are they moving

VHF - collars and radio signals

GPS/Satellite - collars and satellites

passive detection

where are they and when

remotely triggered cameras

acoustic detectors

camera-tapping drives additional technology

merlin, plant net, picture this, inat

molecular techniques

genetics - genotypes

stable isotopes - ratios

bio-markers - loss/gain of isotopes

quantitative fatty acid analysis - mix of unique fatty acids

remote aerial detection

large scale - remote sensing

small scale - unmanned aerial aircraft

statistical and computational advances

enabled by increase computing capacity and speed

four issues in data quality

participation

sustainability

design

user value

participation issues

scale of survey

value of long term observation

observer fatigue

incentives funding

oversight

Design issues

Sampling frame

repeatability

representativeness

variation in detection

technology enhancements

transparency

user value issues

research questions

management needs

community needs

value-added opportunities

communication

feedbacks

abundance

absolute number of individuals

density

number of individuals per unit resource

estimate of abundance

p-hat = 1.0 total detection

p-hat <1.0 partial detection

p-hat function

absolute detection probability

changes with ecological context

changes with observer

area sampled

estimate

when you cant do a census and your index is not trustable

assumptions of distance sampling

all animals in transect are seen subject to distance function

animal counted only once

perpendicular distances measured accurately

sightings are independenta

assumptions of sightability models

animals or sign are encountered with a known probability

counts are accurate

counts are independent

sampling is representative
