People in Pre-History www.AdirondackWildlife.org
Setting the Pleistocene Stage • 2.5 million to 11,400 years ago • Glaciers advanced and retreated eleven times • Ocean levels dropped and rose in response • Glacial Maximum 20,000 years ago • Interglacial Ocean rises restricted intercontinental movement, while enabling intracontinental movement • Neanderthals, large mammals and their predators spread across the north • Glacial Ocean drop enabled intercontinental movement, while restricting intracontinental movement • Neanderthals and wildlife were driven out of the north, placing them in the path of expanding homo sapiens. www.AdirondackWildlife.org
Genus Homo - Humans Out of Africa • Homo Habilis in Africa • 2.3 to 1.4 million years ago • Homo Erectus: Africa, Asia & Europe • 2.2 million to 140,000 years ago • Common ancestor with Habilis? • Homo Neanderthalensis • 150,000 to 30,00 years ago in Europe & Mid East • Homo Sapiens • African genesis 200,000 years ago • Small group of Wanderers became Humanity’s Adams & Eves, leaving Africa 60-100,000 y.a. 1. Homo Sapiens, 2. Neanderthal, 3. Early Hominids, Wiki www.AdirondackWildlife.org
How Genus Homo Changed History • Mastered Fire • Warmth • Cooking, about 250,000 yrs ago • Security from dangerous Predators • Short-faced Bear • Saber Toothed Cat • Dire Wolf • Larger social groups made pre-Homo frugivore diet unsustainable • Learned to scavenge Meat • Hunting game Incredibly Dangerous • Made Crude Tools and Weapons • Erectus shows evidence of the “Throwing” Shoulder • Neanderthals Converse & create totems? • Homo Sapiens Developed Language & Animistic Religion • Pre Historic Cultures are extremely war-like www.AdirondackWildlife.org
Dire Wolf Mark Hallett, Paleoart • Pleistocene wolf • Most common mammalian find in LaBrea Tar Pits • Larger than Grey Wolf • Driven to extinction about 10,000 years ago www.AdirondackWildlife.org
People & Wolves www.AdirondackWildlife.org
Competing & Living with Wolves • Competed for meat with Wolves & other predators • Learned to steal Meat from Wolves • Inadvertently Provided Meat for Wolves and other Scavengers at the Bone Pile • Took in occasional orphaned wolf pup • Wolves became early warning system for dangerous predators or intruders • Provided Meat for Wolves at the Campfire • Accidental tactical cooperation during hunting, with each exploiting the other species strengths & tactics • Unnatural, forced selection led to dogs • Geographical, Topographical & Glacial Isolation drove diversity in humans & their “dogs” www.AdirondackWildlife.org

Wolves and Dogs • Wolf Packs are Families • Wolves are territorial • Wolf packs are hierarchical • Dogs are like Wolves. • Emotionally Transparent • Living in the Moment • Dreams & Actions • Cats and Dogs • Wolves are like People. • Mom & Dad are the “Breeding Pair” • Dogs are like Us. www.AdirondackWildlife.org
Dogs & People • Dmitri Belyaev1959 experiment with selecting & breeding tame silver foxes • Less adrenaline in Tamer foxes • Shorter limbs & tails • Floppy ears & curly tails • Left gaze bias in both Humans & Dogs • Sympathetic bias towards infant faces • Neotonousselection for breeding • Oxytocin release in dogs & owners • Wolfs bark or “woof” as a warning • Dogs developed barking to communicate with us • Heart attack survival & occurrence • 500 million dogs in the world, about 500k wolves Silver Fox, Wiki www.AdirondackWildlife.org
Dogs & People • Natural Selection: Survivors Breed • Unnatural selection, or “Eugenics”: Selected Traits Predominate & Become Exaggerated • Decline of nature’s fitness restrictions allows alternate phenotypes, or “funny” looking dogs, to survive and breed • Tandem Repeaters more prevalent in Canids • Physical Traits may be controlled by fewer genes, making selective breed alteration easier to achieve… • While messing up pure breeds: 1 in 4 have genetic issues with recessive genes expressed. • Independence from seasonal weather affects estrus frequency • 80% of 300-400 breeds developed in last 130 years • Dogs were selected for cooperation, for responding to our social queues • Dog’s olfactory orientation married to our visual orientation www.AdirondackWildlife.org

Adirondack Wolves • Known by Many Names • “Coy Dog” • “Coy Wolf” • “Adirondack Wolf” • “Brush Wolf” • “Tweed Wolf” • Eastern Coyote • Hybrid of Wolf & Coyote • Harmless to People • Dangerous to Pets • Killing Coyotes is counter-productive Coywolves, at ADK Wildlife Refuge Trail cam, Dec 2011 www.AdirondackWildlife.org

DNA Confirms!Wild Wolves are in the Adirondacks • 8 wolves were killed in DAKs , Vt & Maine last 20 years • Wild wolves or Escaped Pets? • Carbon Isotope Isolation Reveals Whether Food sources were wild (C3) or domestic (C4) • 3 of the wolves tested wild • Eastern wolves or gray wolves? • Are returning wolves breeding with coywolves? • Findings may affect legal status Emily Schmitt Roland Kays, Curator of Mammals, NY State Museum www.AdirondackWildlife.org
Trophic Cascades:Wolves in the Context of their Environment Emily Schmitt www.AdirondackWildlife.org
Where the Wild Things Were • Nature is a Top-Down System • Predators • Herbivores • Plants • Trophic Cascades • Otters, Kelp & Killer Whales • Conservation Biology & Biodiversity www.AdirondackWildlife.org http://www.lausd.k12.ca.us/Figueroa_EL/lifescience4.htm
What Happens to Herbivores & Plants when you Remove Predators? • Herbivores afflicted with infectious, contagious diseases are not removed by predators. • CWD- Chronic Wasting Disease • EHD- Epizootic hemorrhagic disease • Larger number of herbivores over-browse target vegetation & enable spread of invasives. • Favor browsing native species • Learn to browse invasive species, & end up spreading seeds around. • Over-browsing can lead to prey collapse Garlic mustard Common Reed Grass Japanese Knotwood Purple Loosestrife www.AdirondackWildlife.org
Factors needed to ensure Ecosystem survival:Cores, Corridors & Carnivores • Inaccessible wilderness • Wildlife Corridors • Understanding & Appreciating the Role of Predators in nature • Compassion • Appreciation of Tourism Effect www.AdirondackWildlife.org
Adirondack Park • “The lands now or hereafter constituting the Forest Preserve shall be forever kept as wild forest lands…”New York State Legislature in 1885 • Largest Protected Park in the U.S. • 6 million acres - 9,400 sq miles – 24,300 sq km • Larger than Vermont • Larger than Yellowstone, Glacier, Yosemite, Great Smokey & the Everglades combined! www.AdirondackWildlife.org
Why encourage wolves in the Adirondacks? • Forever Wild? • Wolves Control Deer & Beaver • Will they Control Coywolf? • Tourism provides jobs • In 2007, the Adirondacks took only 2 % of total NY tourist dollars! http://www.dec.ny.gov/images/lands_forests_images/ www.AdirondackWildlife.org
Why encourage wolves in the Adirondacks? • 25-50,000 Hunters spend $17 to $35 million in Adirondacks per season. • 2006 Survey: 3.5% of total tourists to Yellowstone came just to see wolves, adding $30 million per year to local tourism. • If there are 7 to 10 million tourists to DAKs per yr, and if an additional 3.5% come to see wolves, might add $125 to $165 million to ADK economy. • Hunting Outfitters expand seasonal business to yr. round, adding Photographers & Tourists • Wolves are no physical threat to People http://www.dec.ny.gov/images/lands_forests_images/ www.AdirondackWildlife.org
Factors affecting Wolf Reintroduction • Which wolves actually lived in the Adirondacks? • Gray Wolf, Canis Lupus, or Eastern Wolf, CanisLycaon? • Suitable Habitat in Wilderness Areas? • Accessibility to Other Gene Pools? • “Corridors” local & regional? • Increasing Moose population • Increasing Beaver Population • Stable White Tail population • 26.8k deer harvested in DEC Northern Zone 2011 • Public Acceptance & Education http://www.cosmosmith.com/eastern_timber_wolves.asp www.AdirondackWildlife.org
