Unusually heavy rains this summer are partly to blame for rats pouring out of the sewers
in droves all over the country. And the nasty vermin are relocating to some of the most
pristine neighborhoods. The Great Lakes Radio Consortium’s Joyce Kryszak explains what
caused the rat invasion and what’s being done to evict them:


Piercing blue autumn skies and billowing white clouds drift across the chimneys of this modest,
but perfectly manicured suburb. There aren’t even many leaves crunching under foot. Town workers
have already come and vacuumed them all away. But there’s a nasty little secret scurrying under
the porches and behind the garden sheds in this Western New York town. County Sanitation Chief
Peter Tripi takes us for a peek.


“Can you see the teeth marks here? That’s actually rat gnaw marks. And there’s the garbage bag.
And that’s what we found when we went to this property.”


Now, you might be thinking that we trudged through derelict grass and scattered debris to find
these rat clues. Nope. This is a gorgeous, manicured yard – with not a blade of grass out of
place. But Tripi says rats aren’t choosy.


“You would never think by looking side to side that there would be a rat problem in this yard.
Doesn’t matter what neighborhood you live in, or how much money you’ve got. There’s no difference.
They just like your food.”


And you’d be surprised where rats can find food. A garbage can left even briefly uncovered, a
neglected bird feeder, uhhh… dog feces… and even a compost pile.


“Absolutely. This is a rat condo. It’s a grass-clipping compost pile that basically housed rats
to go a hundred yard radius all the way around to the different houses.”


Tripi says rats had to get creative with their housing. A summer of extremely heavy rains drove
the out of the sewers and into some previously rat-free neighborhoods. And with the West Nile
virus killing off millions of birds, the rats have less competition for the food they’re finding
above ground. The consequence is a virtual rat infestation all the way from New York and Illinois
to Virginia, Michigan and L.A. In Kenmore, there have been four thousand rat complaints – nearly
double last year.


(Sound of garbage truck)


Of course, none of this is news to the garbage collectors. They see the problem up close and
personal. Twenty-year veteran Louie Tadaro says this past summer is the worst he’s ever seen.


“Across the street there’s an alleyway and there had to be like ten of them in there, And we
started chasing them with garbage cans trying to kill them, but we couldn’t. By the time we
got there they just split.”


The problem is, they don’t split for long. Vector Control Chief Tripi says now that the rats
have relocated from the sewers to upscale accommodations, they kind of like it.


“And what that means is that they want to live with us. They want to be near our garbage and
our bird feeders. The problem with that is that rats carry diseases.”


We all know about stuff like typhus and the bubonic plague. But there are emerging diseases,
such as a pet-killer called Leptospiroris. It’s killing dogs all across the country. Tripi
says they need to get rid of the rats before the disease starts spreading to humans. So, his
team is taking the rats on, one yard at a time.


Tripi and his Vector control team set rat traps, they fill bait boxes with poison, and – when
they have to – they issue citations to residents who don’t heed the town’s new “rat control rules.” Covered garbage cans only. Clear away all brush. Clean up scattered bird seed and dog feces. Slowly, the rules seem to be working.


(sound of Tripi looking into rat trap)


Still Tripi says it’s mostly educational warfare. And he says now – heading into winter – is the
best time to nip the problem. If the rats get cozy, not only will they stay, they will multiply.
Fully nourished, one adult rat can breed up to sixty baby rats a year.


“The adult rat can live on a little bit of food, but he can’t procreate unless he has a lot of
food source. And they can’t live through the winter unless they’re warm and fattened up.”


So now is the time to – quite literally – put a lid on it. Keep those garbage cans covered, unless
you want some uninvited furry guests this winter, and many, many more come spring.

Essay: Mourning the Destruction of a Flower Garden

It’s the time of year when many gardens reach their peak – and even grow a little bit wild. That has made one essayist’s loss all the more painful. The Great Lakes Radio Consortium’s Karen Kelly remembers a special garden:

It’s the time of year when many gardens reach their peak –
and even grow a little bit wild. That has made one essayist’s loss all the more painful.
The Great Lakes Radio Consortium’s Karen Kelly remembers a special garden:


It looked like a crime scene.


Everything in the garden was gone.


The morning glories no longer crowded the sidewalk. Sunflowers were cut down in their
prime. There was a hole instead of the lilac. And one stubby trunk – where someone had
hacked off the sand cherry tree.


We started the garden just over a year ago. I found out I was pregnant and next thing I
know, my husband is incubating black-eyed susans on top of the refrigerator.


He seemed to have that nesting instinct. Suddenly, he was spending every weekend at
the nursery. He came home with tools and soil and plants and even trees.


The scraggly yard in front of our apartment building was being transformed.
For me, it was just what I needed – a patch of nature in the middle of the city.


This summer, the flowers came back. And we shared the garden with our 6 month old.
We were pointing out the buds on the trees, and the bees buzzing around.


We didn’t tend it much as we got ready to move. And it grew pretty wild.
There were flowers, but also grass and weeds.


Two weeks after we moved, all that life was torn up. Eleven different kinds of plants – all
carefully chosen and tended. We visited them every time we walked in or out of the
building.


I can’t imagine the person who could just rip flowers out of the ground. It was a tiny,
imperfect oasis. Now, it’s just dirt.


Ironically, the only thing that survived was a plum tree we planted on the city property –
between the sidewalk and the road. We thought city workers might pull it up – since it
wasn’t official. Instead, they plunked an iron gate around it and now, every week, a city
truck comes to water it.


We always laugh about how it survived its brush with the city officials.


Now, that tree has proved it really is a survivor – but all that perennial color that was
once a backdrop to it is gone. It was not just a bit of our past, but an investment in the
future as well.

Birders’ Passion Helps Scientists

Every year, tens of thousands of avid birdwatchers wander through frozen fields and marshy swamps. Their job is to record as many birds as they can find in a given area. For birders, it’s a day to enjoy the outdoors while doing what they love most.

Every year, tens of thousands of avid birdwatchers wander through
frozen fields and marshy swamps. Their job is to record as many birds
as they can find in a given area. For birders, it’s a day to enjoy the outdoors
while doing what they love most. But as the Great Lakes Radio Consortium’s
Karen Kelly reports, that passion serves another purpose – it helps scientists:


(sound of footsteps)


Georgina Doe: “There’s five robins right there and there’s three common mergansers,
males…”


Georgina Doe scans the shoreline with her binoculars. Within seconds,
she spots a tiny glimpse of a bird and names it.


She knows them by the way they dive in the air, and the way they thrust
their chests out.


Doe has been scanning the treetops of Carleton Place, Ontario for
more than 30 years. She says she loves the chase and the element of surprise.
And over the years, birding has also been her escape.


She remembers watching a robin build its nest when her grandson
was seriously ill.


“So I used to count the birds every morning before I went off to
the hospital. And then after that, you come back to reality. Somehow a
little bird can just make you feel better.”


Birds have been a part of all of our lives. We might not know their names.
But we can remember holding a baby chick. Or hearing a cardinal on a crisp cold day.


But now, many bird species are dwindling. And scientists are
counting on birders like Georgina Doe to help them find out why.


Doe is one of many birders in North America who collects
information for scientists. Jeff Wells works with that information
at Cornell University’s Lab of Ornithology.


“There’s no way that we could ever pay the tens of thousands of
trained biologists that would be necessary to gather this kind of
information. It’s only possible when we can engage volunteers like
we do in citizen science projects.”


Cornell runs at least a dozen programs that rely on information
from average birders.


There’s the Christmas Bird Count. About 50 thousand people participate.
Another 50 thousand track species during the Great Backyard Bird
Count in February.


The volunteers reported that wood thrushes are disappearing in
many areas. And they’re tracking the effect of the West Nile Virus
on bird populations.


“If a little bird dies, usually it just disappears quickly
and no one ever sees it. So we don’t really know the impact.
And so looking at the differences in the numbers and distribution
might give us some sense of when the disease was rampant in the summer,
whether it killed off enough birds to make a noticeable
difference in our count.”


(sound of quiet footsteps)


Robert Cermak: “You can see it’s about 10 inches high. It’s all fluffed
up right now so it’s
hard to get a sense of
its mass…”


Birder Robert Cermak tiptoes closer to a barred owl sitting in the
crook of a tree.


We’re in Ottawa, Canada’s capital and a city of about a million
people. When it comes to bird counts, this is Cermak’s territory.


“It’s not often that you actually see a barred owl, any owl, during
the day. They’re usually more secretive. This one is not too
afraid to be out so it’s probably become more accustomed to having people
around it, since this is the center of the city.”


Like Georgina Doe, Cermak has been birding for years. But even with
veterans, there’s always concern about their accuracy. Cermak
discovered this firsthand when he reported seeing a rare
harlequin duck last year.


“I sent it in and a few hours later, someone from Cornell –
very politely because it’s a delicate subject to question
someone’s sighting of a rare bird – but they very delicately
indicated that a harlequin duck is extremely unusual in Ontario and
could I please provide a few extra details.”


Cermak sent them a published account of the sighting. He also
gave them the number of a local expert.


Jeff Wells says researchers check their facts carefully. They look
for reports that don’t match others in the surrounding area. Sometimes
an investigation turns up a trained ornithologist… and sometimes not.
But overall, Wells says the information has formed the basis for
hundreds of published studies.


That’s something that makes birders like Robert Cermak and
Georgina Doe feel proud.


“It’s nice because you’re contributing. You’re doing a
lot of hours, it uses a lot of gas, you go around a lot of blocks doing this
kind of count
but we just think it’s important.”


(sound of Georgina Doe walking)


Georgina Doe says she doesn’t really think of herself as a
scientist.


But she’s out there every day, with her ear to the wind. And that’s
what the scientists are counting on.

Virgin Shark Birth Sets Researchers in Motion

A female shark in an aquarium in the Great Lakes region has apparently given virgin birth. Four shark eggs hatched last year and three of those babies are now growing normally.

A female shark in an aquarium in the Great Lakes region has apparently given virgin birth. Four
shark eggs hatched last year and three of those babies are now growing normally. As the Great
Lakes Radio Consortium’s Celeste Headlee reports, it may be some time before the cause can be
determined, but the event is still a surprise for biologists:

Biologists have a technical term for virgin birth. It’s called parthenogenesis. Doug Sweet is the
Curator of Fishes at the Belle Isle Aquarium in Detroit. He says parthenogenesis is common in
invertebrates and some amphibians.

“Most vertebrate animals, the females will produce eggs even if the male is not around. And it’s
just a matter of… it’s a chemical trick, basically, to get that egg to develop into an individual
without a sperm activating it.”

But parthenogenesis has been totally unheard of for sharks, until now. Last year, the Henry
Doorly Zoo in Omaha, Nebraska, announced they thought a Bonnethead shark there had
reproduced by parthenogenesis. The baby lived less than 12 hours, though, and genetic tests were
inconclusive.

But when Doug Sweet saw the press release from the Henry Doorly Zoo about a possible virgin
birth, he thought he’d try an experiment. Sweet decided to incubate the eggs of his two female
bamboo sharks. Four of the eggs developed. Sweet says the sharks were acquired by the
aquarium before they had reached sexual maturity, and they have never been exposed to a male.
He says the likely conclusion is that these sharks are reproducing by parthenogenesis.

Two other explanations, though highly unlikely, are that the shark has both testicular and ovarian
tissue, and fertilized its own eggs or that sharks are capable of storing sperm for years and even
passing it down to their offspring. Sweet has sent small clippings from the sharks’ fins to the
Henry Doorly Genetics Lab. Testing has already begun, but Sweet says it could take more than a
year to get the results. In the meantime, Sweet says the facts remain the same: a female shark
has given virgin birth. If it is parthenogenesis, he says, it will have important implications for
biologists around the world.

“Parthenogenesis just hasn’t been considered to happen in sharks; it’s never been recorded. It may
be happening all the time out there, so this is kind of breaking news in the shark world.”

The two adult bamboo sharks and the offspring are currently on exhibit at the Belle Isle
Aquarium in Detroit.

Therapeutic Diapers

Each year in the United States, about four-hundred thousand fulltermbabies will be treated for jaundice. Since a baby’s liver and otherorgans aren’t fully developed, they often can’t process a substancecalled bilirubin (billy-roo-bin). The bilirubin causes a yellowishtinge to the skin and is usually treated with phototherapy.Now, one woman has found a way to speed up this process.
