(Jun 27, 2023) The Adirondack Guideboat is a very particular craft. They're made of wood and thousands of screws and tacks. They're wider than a canoe, and rowed instead of paddled. They're only used in the Adirondacks, and they were the boat of choice for professional guides in the 19th and 20th centuries. Very few people still build and repair th…

(Oct 28, 2021) Ravens were once a rarity in the North Country, but now they are becoming a common sight. They have a similar appearance to crows, but if you see the two birds together the difference is fairly obvious. Curt Stager and Martha Foley discuss ravens and crows on Natural Selections.Por Natural Selections

(Oct 21, 2021) The pressure to keep billions of humans fed can have a transformative impact on amimal populations. Overharvesting that targets the largest animals can result in reduction of the average size of species, as seen in Caribbean conch snails. And sport-fishing pressure on large mouth bass can winnow out the most agressive in the gene poo…

(Oct 14, 2021) Keratin, the substance wool, hair, and feathers are made from, makes a pretty thin diet, but the clothes moth has been dogging humanity's closets and drawers for hundreds of years, unravelling the work of generations of knitters and weavers to feed its larvae.Por Natural Selections

(Oct 7, 2021) Of all the places a cat can hang out, why do do many of them want to hang out in boxes? According to researchers, cats that spend time in close confines are measurably less stressed than those remaining in the open. As Curt Stager tells Martha Foley, it's not just house cats who feel this way.…

(Sep 30, 2021) Martha Foley has never succeeded in keeping a nature journal long-term, but Curt Stager finds them invaluable in his work. He records his observations on paper, but also finds great data through researching the journals of past observers, from Samuel de Champlain to Thomas Jefferson, to ordinary little-known North Country folk. His h…

(Sep 28, 2021) Sometimes it's not the subject, but the moment that captures an artist's attention. And St. Lawrence County artist Bill Parmer loves to spend time in his pickup in a favorite habitat: along a back road looking for just the right rural landscape in just the right light. You'll find many of Bill Parmer's original oil "plein air" painti…

(Sep 9, 2021) The complex web of species interaction is full of odd associations. Stocking a lake with fish cuts down on dragonflies, which helps pollinators, which helps the flowers bloom. Or it can cut down on amphibians such as newts, which is bad for garter snakes. Invasive flowering purple loosestrife is good for insects and birds that feed on…

(Sep 2, 2021) Martha Foley? - not a fan of bugs. And Curt Stager took a course on them to steady his own reactions. The Natural Selections team looks at the outliers on the spectrum, the largest and smallest of critters with too many legs. New Zealand's weta makes a real handful. The fairy fly is nearly invisible. Some prehistoric dragonflies were …

(Aug 19, 2021) The ubiquitous bird of cities and towns was designed for a different environment. The pigeon's distinctive style of flight is adapted for maneuverability in tight places - near vertical takeoffs and quick changes of direction. This adaptation to cliff and mountainside environments serves them well among our urban cliff dwellings. Cur…

(Jul 29, 2021) Animals that resemble each other may not be closely related. Sometimes the setting shapes their bodies more than their ancestry. Manatees may look like whales or walruses, but that is only because they adapted to the marine environment in a similar way. Martha Foley and Curt stager talk about convergent evolution.…

(Jul 15, 2021) Lake trout require a lot of cold, oxygenated water to survive. Lakes in the Adirondacks of upstate New York are at the southern edge of their natural range. Although about 100 Adirondack lakes and ponds are still home to lake trout, even a small increase in temperature could sharply cut that number.…

(May 21, 2021) In early March, the snow crunched underneath Erica Burns’s boots as she walked from the horse barn to the pasture. A white horse had dug through the snow to find some grass and was grazing. “This is Lola. She’s our oldest horse,” Burns said. “That one’s Clover. Hey, Clove!”Por Andy Flynn
