Ponds around the world--Indiana
.
Coastal plain ponds are a rare and endangered ecosystem. Although most are found along the Atlantic coast north of New York City, Indiana claims a few. They are located SE of Chicago--one could say on the coastal plain of Lake Michigan.
They are found in Jasper-Pulaski State Park, famous as a place to view Sandhill Cranes during migration (below).
"Although a popular destination for hunters, anglers, and Sandhill Crane enthusiasts, few are aware of the global significance of Inland Coastal Plain ponds and marshes at Jasper-Pulaski. These ephemerally wet, shallow basins are host to an impressive array of unusual flora.

Coastal plain ponds...
...are a unique and rare ecosystem found from New Jersey north along the Atlantic coast. They include the amazing ponds of Cape Cod. Some people consider seepage ponds in Midwestern states--formed along the glacial margin like those on the Cape-to be close relatives.

Ponds around the world--Switzerland

"Global warming, a concern for its effects on the world's oceans, is also causing harm to the globe's freshwater lakes, researchers in Switzerland say.
Researchers... said a study of Lake Zurich showed that because of global warming, there is insufficient water turnover in the lake following the winter and harmful algae known as Burgundy blood algae are increasingly thriving.
Lake Zurich, by Chris Brown
Many large lakes in Central Europe became heavily overfertilized in the 20th century through sewage, and as a result algal blooms form, reducing oxygen content in the water and threatening fish stocks, they said.
Dead fish in Shangri-La

All around the world, lakes are in trouble--with fish kills or toxic algae blooms. Usually, the culprit is excess nutrients washing into the lake. It's happening even at pristine lakes, long thought to be immune to these problems.
From time to time, I'll feature problems of lakes in a different parts of the world. The root cause is growing populations and affluence, plus the difficulty of managing thousands of small sources of nutrients.
Indian Kashmir used to be a place people compared to mythical Shangri-La--verdant and unspoiled. And Nigeen Lake (above), in a green valley surrounded by the Himalayas, is considered by waterways officials to the least polluted waterway in the city of Srinagar (population 1.3 million).
But a few days ago, there was a big fish kill on the lake. "The fisheries department has attributed the deaths to depletion of oxygen, fluctuation of temperature and flow of untreated sewage into the lake." Residents say they've never seen anything like this before. Source

Toxic algae bloom reported in Eastham
.
"Town officials are warning swimmers and pet owners to avoid Molls Pond off Alston Avenue because of the growth of blue-green algae." The problem was noticed when a dog became sick, after drinking from the pond.
"Possible health effects range from rashes, hives or skin blisters to runny eyes and nose, sore throat, diarrhea and vomiting. In rare cases, exposure can lead to neurological symptoms, including drooling, weakness, staggering, convulsions, and death in dogs. Humans may experience dizziness, numb lips or tingling fingers.

The Future--Cleaning up the Cape's algae problem
"Everything about the Cape functions around its ability to have clean beaches, abundant shellfishing,
and all the tourism spinoffs.
Our product, you can say, is clean water.’’*
CLF Cleaning up the Cape’s Algae Problem
Nov 30, 2011 by Ben Carmichael Source
"Rotten eggs and black mayonnaise – sights and smells that, to the dread of many, are becoming increasingly common across Cape Cod. Over the 30 years, increased development and insufficient wastewater treatment systems have degraded the quality of Cape Cod’s waters. CLF, in association with Buzzards Bay Coalition, are working to clean up the Cape – work that was recently covered by David Abel in The Boston Globe.

Take the skull challenge...
Can you name the wetland animal that matches each skull?
The relative sizes are shown. The largest is 7 3/4" long, and the smallest is 2 3/8" long.
A. hint: omnivore (eats a wide variety of animals and plants). Not aquatic, but often feeds along the shores of ponds and streams.
B. hint: herbivore (eats plants); round tail. Very aquatic.
C. hint: mostly a carnivore (eats animals). Not aquatic, but travels along shorelines.
D. hint: omnivore (eats a variety of animals and plants). This animal is not a wetland species, but might be found along the shore at times.
E. hint: carnivore (eats animals). Very aquatic.
F. hint: herbivore (eats plants), flat tail. Very aquatic. This is the only one of the six skulls which does not occur in Cape Cod and SE Massachusetts--but it is common elsewhere. Bonus points if you can come up with a good answer for why it's not found in Cape Cod!
