Biology Case Studies Flashcards
what is your invasive specie? (JP BBRY)
how does it look like?
background?
location of sightings in ON
damages on ecosystem
control measures to stop it
japanese barberry –> latin = berberis thunbergii
round leaves that are green, oval shaped berries that are red
originated in arnold arboretum, boston
southern parts of CA like: ON, Quebec, + NOVA SCOTIA
dense thickets reduce wildlife habitats, impact agriculture causing diseases + dam. / loss to gain crops, + shade out native species in forest understory
avoid invasive plants in garden, don’t dispose in compost pile, keep pets on leash in trails
what is your invasive specie? (EWCN)
how does it look like?
background?
location of sightings in ON
damages on ecosystem
control measures to stop it
european water chest nut
green, spiky top + round bottom, lines in leaves
originated = ottawa river
introduced = through improper release of water garden plants
wolfe island –> lake ontario Rideau RIver –> Ottawa
St. Lawrence Rv. –> Kingston
Niagara River
shape spines made on shore = injury
large amounts of decomp. veget. = decreased oxygen lvl = kill fish
clean, drain, dry boats
don’t depost unwanted aquarium or water garden plants into lakes + rivers
don’t buy or keep
Lake Erie Story
chemicals fell in water = algal growth choke water organisms, then oxyg. = fish die = U.S + Canada clean and restore biological integrity
Easter Island Story
unlimited popuation growth + overexplotation caused population crash (carrying cap.) = too much
