Exotics/wildlife management Flashcards
domestication
tame and bred for human use with suppression of natural instincts with genetic change
characteristics of domesticated animals?
flexible diet, fast growth rate, amenable to captive breeding, good disposition, stable temperament, modifiable social hierarchy
imprinting
process by which an animal learns to identify itself with a person
taming
process where an animal becomes socialized/desensitized to humans over time
habitat fragmentation
humans encroaching on wildlife which splits species far apart from each other
creates issues with breeding and inbreeding increases which leds to a bad genetics pool
translocation
moving animals to different spaces or reintroducing a species to an area they used to be apart of
not always successful, careful to think about how the change could effect the ecosystem
what are some common issues that have arisen from translocation?
stress, introducing disease, bothering other species/unbalancing ecosystem
when did industrialized farming start?
after WWII when the industrial boom occurred
was only meant to be short term so we could get back on our feet after the war
how is industrialized farming done and what are the benefits of it?
it is done through the use of pesticides and fertilization
benefits: high density, high yield, and low cost farming
CAFO’s
concentrated animal feeding operations
uses antibiotics and hormones on animals
causes pollution in the water surrounding these farms
why are amphibians so important to watch?
they are very sensitive to environment changes so we can use them to see if changes need to be made
currently they are having sex changes and genetic changes like ending up with multiple heads = not good
POPs
persistent organic pollutants
OWCs
organic wastewater compounds
ex: excreted hormones, pharmaceuticals, detergents and household products
bioaccumulation
increased concentration of a pollutant in an organism
biomagnification
increased concentration of a pollutant in a food chain
