Data Collection Flashcards
Morfological measures:
Measuring a variety of anatomical characteristics, to distinguish (characteriscs of) an
individual
2 categories of morpholical measures:
- Simple measures, eg biometric measures
- Complex measures
- Body Condition Score (BCS)
- Teeth/ Dental wear
- Facial Expressions
- Pain-score
Biometric measures
- Size of bodyparts, height (withers)
- Weight
Heart Rate =
beats per minute
Heart Rate variability (HRV):
Based on Length of
Inter-Beat-Intervals (IBI’s)
High HRV:
- High variance in IBI’s,
- Less Chronic Stress
Types of social interactions:
- Agonistic interactions
- Affiliative interactions
Agonistic interactions
Agonistisch gedrag is het gedrag dat een dier vertoont wanneer het niet zeker weet wat het moet doen, dus een mengeling van vlucht- en aanvalsgedrag.
- Aggressive interactions
* Chase, hit, kick, bite, …
- Submissive interactions
* Flee, run, flinch, …
Affiliative interactions:
Friendly and peaceful interactions exchanged among individuals with the function of developing, maintaining, or strengthening social bonds
- grooming
- playing
dominance:
Dominance is an attribute of the pattern of repeated, agonistic
interactions between two individuals, characterized by a consistent
outcome in favour of the same dyad member and a default yielding
response of its opponent rather than escalation
Ad libitum sampling:
writing down anything that seems interesting or important about one animal or a group of animals over a period of time.
Focal sampling:
watching one animal for a set length of time and writing down everything the animal does with the time noted.
instantaneous sampling
In this technique, a particular individual is observed repeatedly, but the behavioral state is recorded at specified intervals. The specific behavioral activity the individual is engaged in at the instant of observation is recorded (hence the name “instantaneous sampling”). For instance, one might observe a fox squirrel at 15 second intervals. At one instant, the squirrel might be searching for food, at another, feeding, at another, chasing a conspecific. The result of this type of observation will also be a time/activity budget, which is derived from the proportion of instantaneous observations in which an individual is engaged in various activities.
Scan sampling:
het binnen een bepaald tijdstip een groep van individuen in ogenschouw nemen en bij allen vastleggen of bepaald gedrag zich voordoet.
camera trap:
remote camera that allows you to “trap” and photograph animals
- Non-invasive
- Relatively simple to
deploy
- Operate without
- supervision
- Provide permanent - records of species, date
& GPS location
- Can record animal
behaviour (video)
- Cost effective over the long term
a camera trap can be used for:
species distribution,
density, frequency, activity patterns, habitat preferences, population demographic parameters
differences and considirations camera traps:
- Detection circuit (=
Σ detection zone + trigger
speed + recovery time) - battery type
- storage memory
- photo vs video
- weatherproof
- security
pain score in mice:
Mouse Grimace Scale
which are the 6 criteria of painscore in mice?
- orbitale aanscherping
- neusuitstulping
- wanguitstulping
- oorpositie
- snorhaarverandering
which are the 6 criteria of painscore in cows?
- aandacht rondom de omgeving
- hoofdpositie
- oorpositie
- gezichtsuitdrukking
- reactie op aanpak
- achterste positie
- kreupelheid
