Grizzly bears, black bears, wolves, coyotes, cougars/ mountain lions,bobcats, wolverines, lynx, foxes, fishers and martens are the suite of carnivores that originally inhabited North America after the Pleistocene extinctions. This site invites research, commentary, point/counterpoint on that suite of native animals (predator and prey) that inhabited The Americas circa 1500-at the initial point of European exploration and subsequent colonization. Landscape ecology, journal accounts of explorers and frontiersmen, genetic evaluations of museum animals, peer reviewed 20th and 21st century research on various aspects of our "Wild America" as well as subjective commentary from expert and layman alike. All of the above being revealed and discussed with the underlying goal of one day seeing our Continent rewilded.....Where big enough swaths of open space exist with connective corridors to other large forest, meadow, mountain, valley, prairie, desert and chaparral wildlands.....Thereby enabling all of our historic fauna, including man, to live in a sustainable and healthy environment. - Blogger Rick

Any of us who live in Suburbia, Exurbia or rural America know immediately when we see a "McMansion" being built in our community or carved into surrounding woodland and/or farmland...............Usually an oversized compound, many times out of place and yet occasionally(like in the pictures below), quite grand in appearance, these mega-homes are carved into what was open space.................. 15, 20 or 25,000 square foot "castles" they almost always are, with multiple acres surrounding the house denuded of original plant cover............These housing paradigms might not have too negative an impact on the biodiversity of their surroundings if there were just a few of these scattered over many square miles..................However, with 320 million of us now living in the USA, a larger and larger percentage of people have the resources to buy a "piece of paradise" .................As the quantity of these "personal paradises" increase in our woodlands and farmlands, the fractionalization of open space changes the dynamics of predator and prey as well as the compostion of the flora................ It is a scientific fact that this type of land alteration leads to a slippery slope of species eradication, exotic introductions and increased homogeneity of species--------And thus, another "hammer-blow" to the land encouraging the HOLOCENE EXTINCTION, otherwise referred to as the sixth extinction or ANTHROPOCENE EXTINCTION, the ongoing elimination of species and biodiversity mainly due to our human activities, such as building MCMANSIONS

The Rensselaer Plateau is a small plateau located in the central portion of Rensselaer CountyNew York, just east of the state Capitol of Albany.
 It generally encompasses significant parts of the towns of BerlinStephentownSand LakePoestenkill, and Grafton, along with small sections of several other nearby towns. 
Many glacial lakes, including Big Bowman PondLittle Bowman PondRound Pond and Spring Lake are located on the plateau. Elevations on the plateau range from 1,000 to 2,000 feet (305 to 610 meters) above sea level
Vegetation on the plateau is more similar to that found in the Adirondack Mountains to the northwest, with abundant Eastern White PineEastern HemlockRed Spruce, and Balsam Fir, along with more limited occurrences of Red Pineand Tamarack. 
While most to all of the plateau was logged late in the 19th Century and early in the 20th Century, little farming was undertaken afterwards due to extremely poor and rocky soils, allowing much of the forest to regenerate.

What Is Forest Fragmentation and Why Is It A Problem?

What Is Forest Fragmentation and Why Is It A Problem?
Photo by Blake Gardner.
Forest fragmentation is the breaking of large, contiguous, forested areas into smaller pieces of forest; typically these pieces are separated by roads, agriculture, utility corridors, subdivisions, or other human development. It usually occurs incrementally, beginning with cleared patches here and there – think Swiss cheese – within an otherwise unbroken expanse of tree cover.
Over time, those non-forest patches tend to multiply and expand until eventually the forest is reduced to scattered, disconnected forest islands. The surrounding non-forest lands and land uses seriously threaten the health, function, and value of the remaining forest.
Any large-scale canopy disturbance affects a forest, but it is important to distinguish between a forest fragmented by human infrastructure development and a forest of mixed ages and varied canopy closure that results from good forest management. The former is typically much more damaging to forest health and habitat quality, usually with permanent negative effects, whereas the latter may cause only temporary change in the forest.
The effects of fragmentation are well documented in all forested regions of the planet. In general, by reducing forest health and degrading habitat, fragmentation leads to loss of biodiversity, increases in invasive plants, pests, and pathogens, and reduction in water quality. These wide-ranging effects all stem from two basic problems: fragmentation increases isolation between forest communities and it increases so-called edge effects.
When a forest becomes isolated, the movement of plants and animals is inhibited. This restricts breeding and gene flow and results in long-term population decline. Fragmentation is a threat to natural resilience, and connectivity of forest habitats may be a key component of forest adaptation and response to climate change.
Edge effects are even more complicated. They alter growing conditions within the interior of forests through drastic changes in temperature, moisture, light, and wind. Put simply, the environment of the adjacent non-forest land determines the environment of the forest fragment, particularly on its edges. This triggers a cascade of ill effects on the health, growth, and survivability of trees, flowers, ferns, and lichens and an array of secondary effects on the animals that depend on them. Ecologists suggest that true interior forest conditions – you know, where it’s hard to hear cars and lawnmowers and it remains cool, shady, and downright damp even during a three-week drought – only occur at least 200-300 feet inside the non-forest edge.
And so a circular forest island in a sea of non-forest would have to be more than 14 acres in size to include just one acre of such interior forest condition. Put differently, reports indicate that the negative habitat effects of each residential building pocket within a forest radiate outward, affecting up to 30 additional acres with increased disturbance, predation, and competition from edge-dwellers. This may not matter to generalist species like deer, raccoons, and blue jays, which may actually benefit from fragmentation, but it is hell on interior-dependent species like salamanders, goshawks, bats, and flying squirrels. The smaller the remnant the greater the influence of external factors and edge effects. A wise person once likened it to ice cubes: the smaller ones melt faster.
Moreover, as forest fragments become ever smaller, practicing forestry in them becomes operationally impractical, economically nonviable, and culturally unacceptable. In turn, we lose the corresponding and important contributions that forestry makes to our economy and culture. The result is a rapid acceleration of further fragmentation and then permanent loss.
Here is the tricky part: when fragmentation occurs in a heavily forested region like ours, at least in the early going we are still left with a largely pleasant condition. We sense that we still have lots of woods where we can work, hunt, ski, and walk the dogs. And to most of us, this seems good enough, even when the perforations expand and those woods are the scattered remains of a fragmented forest.
But is it enough? At some point when the larger forest is highly fragmented, the size, integrity, and connectivity of those wooded remnants deteriorate beyond recovery and they are no longer adequate for native forest plants and wildlife. After all, when the Swiss cheese has more holes than cheese, the whole sandwich suffers.

How does a solar eclipse affect animals?

Birds may go quiet, bats may fly around and pets may become uneasy, but it's difficult to predict exactly how non-human animals will react.


Russell McLendon; August 3, 2017, Mother Earth Network



A total solar eclipse will soon sweep across the United States for the first time in 99 years, providing a rare spectacle for millions of people. Among the many human onlookers in the path of totality, however, will also be countless wild animals, pets and other creatures with a much looser grasp of what's happening.




Seeing the moon block the sun should be amazing even if you're expecting it. It's presumably a little disorienting if you're in the dark about why you're in the dark.
Our own species was long confused about the nature of eclipses, but the experience must still be very weird for other animals, especially within the path of totality. This is likely a once-in-a-lifetime event for them, too, and while few scientific studies have thoroughly examined their reactions, there are many anecdotal reports of wildlife, farm animals and pets seemingly duped or bewildered by a solar eclipse.
If you're planning to watch the Great American Eclipse this month, here are some things to look for from any non-human animals who might be watching with you — including a new effort to help you share your observations with scientists.

Wildlife

Many wild animals have been known to treat a total solar eclipse like an abrupt midday night. "The birds behave as if the disappearance of the sun means evening, and the return of the sun means morning — in time-lapse, of course," Max Planck Institute ornithologist Wolfgang Fiedler tells German news outlet Deutsche Welle.




That means many songbirds retire to wherever they normally sleep, perform their typical dusk serenade and then quiet down for the "night." When the eclipse ends a few seconds or minutes later, they interpret it as morning and respond with a dawn chorus. This disruption is brief, though, and reportedly doesn't throw off the birds' internal clocks or the broader patterns that dictate things like migration.
Although most reports of eclipse-confused animals are informal observations, there have been some scientific studies on the subject. During a total solar eclipse in June 2001, for example, astronomer Paul Murdin observed how various wildlife reacted at Mana Pools National Park in Zimbabwe. He saw doves and other songbirds act out bedtime routines, briefly going silent before singing when the sun reappeared.
"Egrets, oxpeckers, ibis, trumpeter hornbill and geese stopped feeding and set off for roosts," he wrote, noting that only some returned to feed after the eclipse. A pod of hippos dispersed into the water during totality, as they do at dusk, but then "showed nervousness for the rest of the afternoon" and took a day to get back to normal.
A sun squirrel stayed in his hole on the eclipse day, Murdin wrote, "apparently having concluded from the eclipse that he had overslept into nightfall." Bees withdrew to their hive in the late stages of the eclipse, he added, then tried reconnaissance: "Two scout bees left the hive after the eclipse and returned later, but whatever they reported, the swarm of bees did not leave the hive again that afternoon."
During a total solar eclipse in July 1991, researchers studied responses of orb-weaving spiders in Mexico. The spiders acted normally until totality, when many took down their webs — only to rebuild them when the sun reappeared.
Crepuscular animals often mistake solar eclipses for twilight, too. Crickets and frogs may jump into a dusk chorus, and mosquitoes and midges may start their evening swarms. And in the midst of a total solar eclipse, it can be dark enough not only to quiet down diurnal animals, but also to lure out the night shift. There are many reports of nocturnal animals being active during totality, including bats and owls.
Reactions vary widely by species, though. Baboons recovered quickly from the 2001 eclipse, Murdin wrote, and he saw little effect on crocodiles, lions or zebras. Solitary male elephants "appeared sanguine about the eclipse," he added, "although two did join up and stand passively side by side for the period of greatest darkness."

Pets

With daily routines influenced by human schedules as well as sunlight levels, pets and other non-wild animals often have relatively mild reactions to an eclipse.
Dogs and cats may be confused by a total solar eclipse, or in some cases even frightened, but probably less so than with fireworks or thunder. Totality only lasts a few minutes at most, and an eclipse itself is silent, causing none of the noise that typically scares pets during storms and fireworks. Still, it's generally a good idea to keep pets leashed if they're outdoors with you during the eclipse.
As one Illinois animal-control officer recently told the Southern Illinoisan, pets are more likely to be spooked by crowds of people than the eclipse itself, so their reactions could depend largely on your surroundings. "It's sort of like the Fourth of July, but tripled," he said. "We are going to have concerts, people shooting off fireworks in the dark of the midday sun, loud noises and strangers."

Humans should definitely wear eye protection to watch the eclipse (except during the brief period of totality, when the moon is fully blocking the sun). There are mixed opinions, however, about whether we also need put eclipse glasses on pets.
"On a normal day, your pets don't try to look at the sun, and therefore don't damage their eyes. On this day they're not going to do it, either," said Angela Speck, director of astronomy at the University of Missouri, at a recent news conference with NASA about the August 2017 eclipse. "I'm not going to worry about my cat."
Still, it is possible that some pets could harm their eyes by looking at the eclipse. Cats may be more aloof, but since dogs can follow a human gaze and pointing, it's conceivable that people looking and pointing at the eclipse might tempt dogs to do the same. And thus many people do equip their dogs with eclipse glasses.
Animals on farms and in zoos have been known to act strangely during a total solar eclipse, or to retire as if night has fallen. And when a partial eclipse occurred over Germany in 1999, zoologist Lydia Kolter also noticed a different response from some animals at the Cologne Zoo. "Even if there is no solar eclipse, it can get very dark, very suddenly — for example just before a thunderstorm," Kolter tells Deutsche Welle. "Then, the animals hide in protected areas, because they expect it to rain."
A group of captive chimpanzees showed an eerily relatable response to an annular solar eclipse in 1984. "[W]hen the sky began to darken and the temperature began to decrease, solitary females and females with infants moved to the top of a climbing structure," wrote researchers who studied the chimps' behavior. "As the eclipse progressed, additional chimpanzees began to congregate on the climbing structure and to orient their bodies in the direction of the sun and moon."
"[D]uring the period of maximum eclipse, the animals continued to orient their bodies toward the sun and moon and to turn their faces upward," they added. "One juvenile stood upright and gestured in the direction of the sun and moon."

'Life Responds'


For anyone lucky enough to see the Aug. 21 eclipse, the stars of the show are obviously the sun and moon. But without distracting from the main event, some scientists hope the public will help with a little data collection. Because total solar eclipses are so rare, most of what we know about animals' reactions is still anecdotal


The California Academy of Sciences (CAS) is organizing a citizen-science project, called Life Responds, to document how North American wildlife reacts to the eclipse. Once the eclipse is over, anyone can submit data using the iNaturalist app.
"We're just hoping that people who are watching the eclipse, in places of differing levels of totality, will take some time and observe the animals around them and see how they respond to the eclipse," says Rebecca Johnson, citizen-science lead for the CAS. "A lot of people are interested in studying how animals respond to an eclipse, but as you can imagine it's not a super easy way to set up a research project."
So rather than chasing eclipses around the world to study wildlife, scientists can crowdsource data from hordes of people who will be out observing anyway. If possible, Johnson suggests scoping out your viewing site in advance. "We're asking people to be curious and pay attention, and ideally get out before the eclipse and figure out what animals you might watch and what might be around," she says.
Even if you don't take your eyes off the eclipse, you could keep an ear out for which animals are (or aren't) singing, like songbirds, insects and owls. And beyond animals, Johnson notes that some plants may curl up or unfurl during totality.
As much as humans may understand what's happening during a solar eclipse, we shouldn't feel too smug about the confusion seen in other species. As Johnson points out, we still have plenty to learn about the natural world around us. "There's a lot we probably don't know," she says. "There's a lot we know we don't know."

A Dragon Devours the Sun
Illustration by Adelaide Tyrol
More than 3,000 years ago, the Chinese believed that a dragon ate the sun during a solar eclipse, so they gathered outdoors to drive away the beast by beating pots, pans and drums. Some 500 years later, the Greek poet Archilochus wrote that Zeus had turned day into night.
In Australian Aboriginal mythology, Earth basked in the sun-woman’s heat and light as she traveled across the sky. When the dark orb of the moon-man mated with the sun-woman’s bright circle of light, her fire was temporarily obscured. Traditional Navajo belief holds that anyone who looks directly at an eclipse not only damages their eyes, but also throws the universe out of balance.
Humankind witnesses many dazzling astronomical events, including comets, lunar eclipses and the Aurora Borealis, but nothing inspires the imagination quite like a solar eclipse—those times when the moon’s path across the heavens brings it directly between the sun and earth.  
On August 21, 2017, for the first time in nearly a century, a total solar eclipse will travel across the United States, making a 1½-hour trip that begins at 10:18 a.m. Pacific Daylight Time near Salem, Oregon, and ends at 2:48 p.m.  Eastern Daylight Time around Charlestown, South Carolina. The total eclipse, which will last about 2½ minutes in any given location, will be visible to those who live in an approximately 70 mile wide band along this route: the path of totality. Even in places where the solar eclipse is in totality, the sun’s corona (outer atmosphere) will still be visible beyond the edge of the moon’s obscuring disk.
The farther one lives from the path of totality, the less of the eclipse one will see. From northern to southern New England, the amount of the sun’s disk that is covered will vary from about 50-70 percent, respectively. Over much of New England, around 60 percent of the sun will be masked during the height of the eclipse.
The math that we use today to calculate the path of an upcoming eclipse is based on the same formulas worked out by two mathematicians in the 1800s, Wilhelm Bessel and William Chauvenet, who first predicted the extent of the shadow and duration of an eclipse at sea level. During the past decade, these calculations have been refined to correct for the irregular shapes of the surfaces of both the earth and moon, as well as how the eclipse’s shadow is impacted by elevation on earth. Features on the moon’s surface, such as mountains and craters, create irregular edges to the shadow that is cast on earth, which can alter the length of the eclipse by one to three seconds and cause the width of the path covered by the total eclipse to vary by as much as two miles to the north or south.
During the coming eclipse, scientists supported by NASA will fly two specially-equipped jet planes 50,000 feet into the stratosphere, where the sky is up to 30 times darker than it is at Earth’s surface and images are not distorted by the atmosphere. The eclipse offers an opportunity to obtain more data about the corona, and how this outermost layer of the sun’s atmosphere, where temperatures reach millions of degrees, differs from the lower photosphere layer, which is only several thousand degrees.
For the rest of us, observing the eclipse will be relatively simple. When viewing the eclipse, however, do not ever look directly at the sun, which even partly obscured, can still burn your retinas and cause blindness. One way to view an eclipse is to remove the eyepiece from a telescope and point the wide end of the telescope at the eclipse, without looking through the telescope. Hold a piece of white, non-reflective poster board in the focal plane near the opening where the eyepiece was. Adjust the distance of the poster board from the telescope until the image of the eclipse comes into focus.
Or, hold a pair of binoculars about 12 inches above the poster board, with the eyepiece facing down and the far end directed toward the sun. Position the binoculars so that the image of the eclipse appears on the poster board.
Anticipation has been intense as the 2017 eclipse approaches, and coincidentally our popular culture’s fascination with dragons is on the rise. But don’t be too disappointed if clouds appear overhead on August 21. When the next total eclipse of the sun comes around on April 8, 2024, the path of totality will pass directly over northern New England. The appearance of a ravenous dragon, however, is anyone’s guess.

British Columbia, Canada has just passed a law to end trophy hunts of the big bears in their Province, effective in 2018..............I am not against hunting but as so many biologists have demonstrated over the years, large carnivores like Griz regulate their own numbers..........."One hypothesis as to why this is so is that Carnivores weighing somewhere north of 29-35 pounds self regulate because of slow reproductive rates and development, extended parental care, sparsely populated territories, and a natural tendency towards infanticide, reproductive suppression, and cooperative hunting"............"Additionally, about half of these large carnivores control the numbers within their group by only letting certain members breed"............. A 2nd hypothesis regarding carnivore self regulation centers around these "hunters" being dependent on a given prey base that revolves around a minimum size territory that they can defend and call their own


https://www.google.com/url?rct=j&sa=t&url=https://www.piquenewsmagazine.com/whistler/a-step-in-the-right-direction/Content%3Foid%3D4043966&ct=ga&cd=CAEYCSoUMTUwOTY5Mjc0NjkzODk1NzA0NTIyGjU2ZDFlN2YxOWU4Zjk5OTE6Y29tOmVuOlVT&usg=AFQjCNGRD-UGgeDOaibl0jO_eT0IIqrZuQ


 A Step in the Right Direction 

Grizzly bears have been hunted in B.C. as trophy kills for over 16 years — and for almost as long people have been asking for it to stop.
Indeed, this past February an Insights West poll found 94 per cent of British Columbians said they opposed hunting animals for sport. Since the trophy hunt restarted, about 250 grizzly bears a year have been shot dead for the fun of it.
This week, the freshly minted NDP government announced that it would ban trophy hunting in B.C. starting this November — sadly, the announcement comes too late for grizzly bears this fall as the hunting season opened Aug. 






It's tempting to break out the champagne, but as with all things coming from any level of government the small print needs to be examined.
In this case, the detail not to be overlooked is that hunters can still kill grizzly bears for food — except in the Great Bear Rain Forest, where hunting is to be totally banned.
That's all well and good — most people don't have a problem with people hunting for food.
During the election campaign, the NDP promised to stop the trophy hunt if put in power. Voters were told the plan included a provision that would still allow grizzly bear hunting but only for meat. Hunters would have to turn over any parts of the bear that could be considered trophies — so the hide, the head, paws and so on — to conservation.
At that time, the Green Party went even further saying the meat would have to be butchered and packaged and sent to the hunter's home no matter which country that was in — the hope was that this would act as a deterrent.
This week, however, Green Party leader Andrew Weaver slammed the NDP grizzly hunting-ban announcement.
"Today's announcement will not end grizzly bear hunting in B.C., as many environmental groups have advocated for," stated a Green Party media release.
"In addition, this announcement will create a system in which not all of the animal will be harvested — resident hunters will no longer be allowed to possess the hair, head and hide of grizzlies; this will be 
viewed as wasteful by the resident-hunting community.
"...Foreign hunters will still be able to shoot grizzlies in British Columbia, take a picture of themselves standing over the dead beast, and head back home without harvesting any of the animal."
The Green Party's concerns really stem from the fact that there has been no announcement about how the hunting-grizzlies-for-food plan is going to be managed and enforced. Is someone going to check to make sure that tourist hunters are flying home with their bear meat? Doubtful.
What British Columbians want is meaningful action. Is the NDP announcement welcomed? Of course it is, but voters don't want platitudes, they want action on wildlife preservation and endangered species legislation — not window dressing.
Let's remember that 30 per cent of the grizzlies killed by hunters are female — common sense tells you that in a population of 15,000 in B.C., that is too high a number.
Added to the ongoing threat our own grizzlies face are the changes south of the border thanks to U.S. President Donald Trump.
The trophy hunting industry has successfully lobbied the U.S. administration to take away federal protections on grizzlies.
In an abhorrent move Trump also recently signed into law rules allowing trophy hunters to kill grizzly bears around lures put out to attract them, to target them from aircraft, and to kill grizzly mothers and their cubs in Alaska's national wildlife refuges, where they've always been protected.
And it goes without saying that grizzly bears, like so many other species, are simply facing challenges surviving due to human encroachment on their territory and climate change impacting their environment.
The NDP announcement is welcome but more needs to be done. Let's not forget that grizzly bear viewing brings in millions of dollars in tourism — the Commercial Bear Viewing Association says that bear-viewing has become a major ecotourism revenue generator, bringing in about 10 times more than grizzly-bear hunting.
Let's hope the NDP consultation promised over the next few months produces a plan the grizzlies can live with.

Top Predators Limit Their Own Numbers

2/3/15; by 

Unlike small mammals who multiply like bunnies or some predators who’s boom or bust depends on said bunnies, large carnivores like lions and wolves keep their own numbers in check. According to a new workpublished in Oikos last week, population control is what distinguishes “apex predators” from the rest. 







Researchers have traditionally assumed that the densities of the largest of predators are determined by the availability of their prey supply, but recent studies seem to contradict a bottom-up control. And now, an international team led by Arian Wallach from Charles Darwin University proposes an alternate view: Apex predators naturally have the capacity to limit their own population densities—or self-regulate—helping to keep their ecosystems in balance.
The team tested their idea using a set of life-history traits that might contribute to self-regulation in mammalian carnivores, such as birth rate and investments by parents. They gathered research on more than a hundred species, Science reports, from skunks and stoats to polar bears, panthers, and wolves living in Yosemite. They found that an average weight of 13 to 16 kilograms (29 to 35 lbs) marks a transition between self-regulated carnivores and those that are regulated by external factors.
Small carnivores have fast rates of development and reproduction, as well as higher densities. Large carnivores, on the other hand, have slow reproductive rates and development, extended parental care, sparsely populated territories, and a natural tendency towards infanticide, reproductive suppression, and cooperative hunting, the authors write. 
About half of these large carnivores control the numbers within their group by only letting certain members breed, Science explains. Many of the bigger predators are known to have complex social systems: Dominant female wolves and hyenas, for example, kill the pups of subordinates, and in many large carnivores, the group ends up raising the alpha female’s (or pair’s) pups together. Self-regulation in large carnivores, they conclude, likely ensures that the largest and fiercest never overexploit their resources.
