Remember when people thought Tom Cruise was cool? When he slid
across the floor in his tightie-whities early in his career, the public
fell in love. The scene, featuring a 21-year-old Cruise lip-syncing
“Old Time Rock and Roll” in 1983’s “Risky Business,” has achieved movie
icon status, right there with Marylyn Monroe’s billowing dress and a
tearful Donna Reed in Jimmie Stewart’s arms.
But even with the string of hits that followed, including “Top
Gun,” “A Few Good Men,” “Born on Fourth of July,” “Jerry Macguire” and
the “Mission Impossible” series, Cruise’s popularity has gone belly up.
Today, if you mention his name in polite company, people roll their
eyes and dismiss the Hollywood star as a flipped-out cult member who is
not even worth following in the tabloids.
It turns out that there is a counterpart to Cruise in the
natural world, and it coincidentally shares the name Tom. The Atlantic
tomcod is a poor little fish with a grand past that has relatively
recently lost favor in the public eye.

Is there a coyote in your backyard? Chances are you do share space
with these highly adaptable and smart wild relatives of your family
dog. You may not have seen them around because coyotes mostly roam
their territories at night, looking for food. They eat rabbits,
groundhogs, mice, voles, deer, birdseed, unprotected garbage and
vegetables from your compost pile. They may even dine on your
free-roaming cat or small dog.
It might un-nerve you to know that coyotes prowl your property
as you sleep, but you should not consider them a threat. Rather, think
of them as good neighbors. They are just like any other New Hampshire
citizen who wants to get a place of his own, find true love and raise a
nice family. But, for coyotes to achieve this bliss, they must be
social and hook up with other coyotes in the area. And, like many
people today, coyotes meet others by creating a MySpace page.
No, coyotes don’t open accounts at www.myspace.com to set up a
profile. Instead, they pee on trees. A coyote’s MySpace page is the
scent post that marks its home range or territory. These posts, which
they may “sweeten” with piles of their twisty poo, can be trees, posts,
rocks or any other prominent feature that sits at the edge of their
territory. Coyote home ranges are quite a bit bigger than a Web page,
though, with a core area of two or three square miles and an extended
range of about 25 square miles, depending on available resources.

When you walk outside these days, the cooler air and colorful leaves
clearly indicate change. You can feel excitement brewing in the forests
and fields as animals begin to roam in search of food to fatten up for
the upcoming winter challenges. This foraging behavior is not limited
to the feathered and furred, though. It also applies to political
animals as they grub across the Granite State, fattening up on public
support in preparation for the challenging primary season.
Fortunately for the average citizen, now is the time to enjoy
the parade of both of these hungry animals. You can put out a
birdfeeder and watch wildlife feast right outside your window, or you
can attend one of the abundant presidential candidate events and watch
politicians work up to a feeding frenzy. Better still, you can do both
by enjoying the similarities between some of the most common New
Hampshire animals that come to birdfeeders and the candidates running
for president.

Life is unfair enough without having cheaters in the game. Recent
sports scandals involving doping and game-fixing has left fans
wondering if they are the dopes for cheering on a bunch of crooks. It
turns out that nature has its own share of scandalous cheaters who rig
the game in their favor. Perhaps, by examining these wild cheaters, we
can gain better insight on how to clean up professional sports.
Ecologists have termed nature’s cheaters “aggressive mimics.”
These are creatures that disguise themselves as other animals to gain a
deadly advantage. Put simply, they are real world examples of “wolves
is sheep’s clothing.”
One of the most interesting and relatively common aggressive
mimics is the lacewing. Larvae of this dainty-looking insect are
voracious predators of smaller insects, especially aphids. However,
lacewings have difficulty preying on some species of aphids because
ants protect the aphids like farmers protecting their flock. Some
aphids bribe ants to be their bodyguards by excreting a sweet liquid
called honeydew from their anuses. The ants love this ass-ade and will
attack anything that threatens their sugar daddies.

Father’s Day has passed, and we are reminded once again of what a
worthless holiday it is. Since it was on Sunday, no one got a day off
from work, no schools were closed and no one marched in a Father’s Day
parade. Father’s Day sales were the only “events,” and those were only
for the most stereotypical dad gear—tools, ties and tires. It is time
that we called the day what it really is: “Feeble Attempt at Equality
Day.”
