Transcript of Buttered Popcorn

Moose
Large hebivores
Largest species in the deer family
Diet: Mainly tall grasses and shrubs
Due to the size (height) of the moose, they have difficulties of lowering themselves to ground level
Hooves acts as snowshoes to support their heavy weight
Main predator: wolves
Was first introduced to the island during the 20th century
Isle Royale
1958-1963
Constant abundancy
A very balanced population of wolves and moose
Population of moose was around 500 indivisuals
Population of wolf was around 20 indivisuals
1963-1972
Population of wolf stay roughly around 20 by the end of 1972
Isle Royale
About the island

Isolated by wilderness
Surrounded by Lake Superior
Main focus: the relationship between the wolves and the moose
Wolves
Canivores
Endagered specie
Largest species in the dog family
Diet
Prefers large animals (i.e. deer, elk, moose,etc)
Also eat birds, fishes, lizards, etc
Hunt in pack of 6-12
Main prey: moose
Wolves first arrived to the island in the 1940s by crossing an ice bridge which connected Canada to Isle Royale
About their project
Revolves around the predator and prey relashionship of wolves and moose on Ilse Royale
Started five decades ago, the longest predator-prey relationship
First conducted by Durward Allen in 1958, understood the key of patiency and observing in ecology
The goal of the project was to provide more information to people about the wolves, in hopes of dismissing hateful myths on the wolves
First 5 Years

1980-1982
Wolf population crashed to almost 10 indivisuals by the end of 1982
1996-1997
Population of moose crashed from almost to 800 indivisuals
1997-2006
Wolf population increaced to around 30 indivisuals by the end of 2006
1982-1996
1972-1980
Population of wolf increased to about 50 indivisuals by the end of 1980
2006-2011
The population of wolf decreased to 15 indivisuals by the end of 2011
After 14 Years

After 22 Years

After 24 Years

After 38 Years

After 39 Years

After 48 Years

After 53 Years

Population of Wolf 1963-1972
First few years: wolf population increased from around 20 indivisuals to around 30 indivisual
Around the middle: wolf population decrease from around 30 indivisuals to around 15
Last few years: wolf population increased from around 15 indivisuals to abit above 20 indivisuals
Population of moose increased drastically to around 1250 by the end of 1972
Due to the drastic increase of moose

The perfect ratio of the population of the predator (wolf) vs the population of the prey (moose) shown in the first 5 years was broken
Population of Wolf 1972-1980
First few years: wolf population increased from around 25 indivisuals to around 45 indivisual
Around the middle: wolf population decrease from around 45 indivisuals to around 35 indivisuals
Last few years: wolf population rocketed to 50 indivisuals
Population of moose decreased by half, around 625 indivisuals
Population of Moose 1963-1972
First few years: moose population was increasing slowly
Then: increased drastically
Overall: increased tremendously to around 1250 indivisuals by the end of 1972
Overall: wolf population increased a little
Several mild winters
DUE TO
Overall: wolf population rocketed to 50 indivisuals by the end of 1980
Population of Moose 1972-1980
1972-1978: moose population decreased from around 1250 indivisuals to 625 indivisuals
1978-1979: minor increase of moose population
1979-1980: moose population continued to decrease
Overall: moose population decreased from an estimated 1250 indivisuals to around 625 indivisuals by the end of 1980
Increase of wolf predation
Several severe winters
DUE TO
Moose population increased little, almost no change
The introduction of canine parvovirus ( a type of wolve disease) by humans
DUE TO
Contagious virus thought to be originated from cates
Spreads through direct or indirect with feces (poop)
High mortality rate
Wolf population stayed low for over a decade
Moose population increased to almost 2500 indivisuals by the end of 1996
Decrease of wolf predation
DUE TO
Population of Wolf 1982-1996
1982-1984: wolf population increased from around 10 indivisuals to around 25 indivisuals
1984-1988: wolf population dropped to 10 indivisuals
1988-1989: minor increase of wolf population
Overall: wolf population stayed low for over a decade
1989-1992: wolf population dropped back to around 10 indivisuals
1992-1996: wolf population increased to around 20 indivisuals
The low indivisuals of the wolves were due to inbreeding
SCIENTIST HYPOTHESISED
Minor increase of wolves
Competition for resources
Winter ticks breakout
Severe winters
DUE TO
Moose population decreased to a little under 500 indivisuals by the end of 2006
Population of Wolf 1997-2006
1997-1998: wolf population decreased from 20 indivisuals to around 15 indivsuals
1998-2000: wolf population increased to 30 indivisuals
2000-2002: wolf population decreased to an estimated of 25 indivisuals
Overall: wolf population increased from 20 indivisuals to around 30 indivisuals by the end of 2006
2002-2004: wolf population rose to around 30 indivisuals
2004-2006: minor increase of wolf population
1997 introduction of new Canadian wolves, whom crossed the ice bridge between lake superior and the island which forms occasionally , increase of wolves’ pop
BECAUSE
Population of moose 1997-2006
1997-2001: moose population increased from around alittle below 1000 indivisuals to litle above 1000 indivisuals
Overall: the population of the moose continued to decrease
2001-2006: moose population decreased to alittle below 500 indivisuals
Hot summers
DUE TO
BECAUSE
DURING HOT SUMMERS...
Moose tends to get lazy, lounging in the shady areas, they spend more time resting than eating. They were undernourished, impossible to survive during winters.
Outbreak of moose tick
DUE TO THAT
Increase of wolf predation, as the wolves take advantages of the weakened moose
Population of Wolf 2006-2011
2006-2007: wolf population decrease from around 30 indivisuals to an estimated of 20 indivisuals
2007-2009: wolf population increased to around 25 indivisualsls
2009-2011: wolf population decreased to 15 indivisuals
Overall: wolf population decreased from an estimated 30 indivisuals to 15 indivisuals
Two wolf packs left
Wolves are now near extiction on the island
The population of moose increased 500 indivisuals by the end of 2011
BECAUSE
Using an DNA toolkit they found out that out of the 15 wolves there are only 2 female wolves, and it they do not produce more female clubs the wolves will be extinct by the time the two females dies
DUE TO
Decrease of moose, catching their main prey became difficult
Population of Moose 2006-2011
2006-2007: minor decrease of moose populaion, from around 400 indivisuals to 300 indivisuals
2007-2008: moose population increased to around 500 indivisualsls
2008-2009: moose population decreased to 500 indivisuals
Overall: moose population continued to be low
DUE TO
Ticks
High level of predation
Hot summers
