I don’t often shake down my cat for a dead mouse, but I did think it was fair, considering that he is always shaking me down for his cat food. I wasn’t going to eat his mouse. I needed it as bait, to see if I could catch a burying beetle.
Burying beetles, or sexton beetles, are nocturnal and they spend much of their lives underground. You’re most likely to find them under small dead animals, such as moles or mice, in a field, that is if you get there before the crows, raccoons, ants, worms, or bacteria do. » Continue Reading.
A major new report – The State of the Lake: Thirty Years of Water Quality Monitoring on Lake George – has been released by the Rensselaer Polytechnic Institute Darrin Fresh Water Institute (DFWI) and The FUND for Lake George.
The 72-page report is the result of 30 years of continuous monitoring that found Lake George to be in “remarkably good condition.” However, the report also outlines specific ecological factors that now threaten water quality. Over the 30-year period of the study, researchers found that “while some of the threats to Lake George water quality have receded since 1980, others are worsening.”
The report finds that some of the greatest threats to Lake George water quality include: rising concentrations of salt from continued applications to control winter road ice; the high sensitivity of the lake’s ecological health to even modest increases of nutrient loading (from storm water runoff, septic and sewage systems, fertilizers, and more); and changes in the lake’s food web and fish community in response to invasive species and other influences. » Continue Reading.
Who’s in charge, my daughter wanted to know? She’d been given a tee-shirt that proclaims “Girls Rule The World.” Now she wanted to know: do they? Listen to my answer in this week’s edition of All Things Natural with Ed Kanze.
The podcast is produced by Mountain Lake PBS’s Josh Clement. Listen to past episodes by visiting Mountain Lake PBS’s Borderless North webpage at mountainlake.org/bn.
Biodiversity Research Institute’s (BRI’s) Adirondack Center for Loon Conservation has announced a new campaign on Adirondack Gives, www.adirondackgives.org, the crowdfunding site for Adirondack region nonprofits.
The campaign will provide support for the placement of trail cameras near approximately 30 Common Loon nest sites in the Adirondack Park to document nesting behaviors, clutch size, and hatch dates for Adirondack loons, and to assess the primary factors (e.g., predation, human disturbance) impacting the birds during incubation.
The New York State Department of Environmental Conservation (NYS DEC) provided the cameras for this project. Support from this campaign, which is seeking to raise $1,100 over the next two months, will cover the cost of the lithium-ion batteries and high capacity SD cards used in the cameras. » Continue Reading.
The silhouette of a moose is noticeably different from that of its deer cousins. Its bulky, hunched body sits on tall, improbably proportioned legs. And then there’s that nose. It’s long and broad – a full sixty-five percent of the moose’s head length – with enlarged nostrils that are positioned not in the front of the face, but off to the sides. By the nose alone, there’s little chance of mistaking Bullwinkle for Bambi.
There are traditional explanations for the moose’s unusual looking nose. Wabanaki tribes share tales of the hero Gluskap, who squeezed the moose, shrinking him from a giant’s size and creating an animal with a bulging proboscis. As for a scientific explanation, recent research suggests at least two possibilities. » Continue Reading.
“She’s so cute!” a little girl coos to the snowy white owl. The owl blinks languidly, ignoring her admirer. No doubt she is used to human attention, as she is one of the more popular raptors housed at the Vermont Institute of Natural Science Nature Center (VINS) in Quechee, Vermont. She likewise ignores the decapitated rat in her food bowl, chirruping softly as if dissatisfied with what’s on the menu. I wait patiently, hoping to witness the moment when she gulps it down.
Owls eat their smaller prey whole, or tear larger prey into chunks with their beaks and talons. Sooner or later, that owl will grab the raw rat out of her food bowl with her sharp beak and knock it back like a shot of whiskey. It will slide down her esophagus and into her two-chambered stomach. The first chamber, called the proventriculus, or glandular stomach, secretes digestive enzymes to break down all the easily digestible parts. Much like our own stomach, this chamber will liquefy the soft tissue (the gooey stuff, including muscle, fat and organs). Whatever isn’t digested in the first chamber, such as the bones, fur and teeth, will pass through to the second chamber, called the gizzard. » Continue Reading.
The annual Summer Science Lab at the Tahawus Center in Au Sable Forks is expanding to 5 days, July 14 through 18, 2014. The five-morning workshop accommodates two different age groups in separate sessions: middle school (12-14 years old) and elementary school (9-11 years old). The focus will be on magnetism and electricity for both age groups, with activities in other subject areas, including physics and using microscopes.
Science is always more than a set of explanations,” says instructor Gary Dreiblatt. “Our electricity activities will have students make simple circuits, complex series and parallel circuits, and experiment with the concept of electrical resistance to ultimately build a working fuse. Students will have a far better understanding of electricity and safety through these activities. They will be able to take their electrical kits home to teach a family member and continue their own investigations using d cell batteries.” » Continue Reading.
Around a beaver pond, we sometimes catch a whiff of beaver odor. People have described it to me as smoky, woody, or like tobacco. It may waft over from the lodge, or it might emanate from scent mounds – little piles of mud by the water’s edge. Beavers make scent mounds by dredging up mud from the bottom of a pond, then carrying it up on land in their front paws while walking upright. The beaver drops the mud, then squats over the mound and applies castoreum from glands near the base of the tail.
The smell means: keep away! In some neighborhoods, this territorial advertisement works remarkably well. I’ve been involved in studies where human-made scent mounds effectively deterred free-ranging beavers from settling in unoccupied beaver habitat. » Continue Reading.
A new report—Boat Inspection and Decontamination for Aquatic Invasive Species Prevention: Recommendations for the Adirondack Region—is now available to help guide decisions on where to prioritize actions to prevent the spread of harmful aquatic invasive species (AIS).
This first-time analysis for the Adirondack region summarizes the best available science, analyzes current AIS distribution and boater use patterns and recommends initial locations to consider integrating boat inspection and decontamination to prevent landscape level spread of AIS.» Continue Reading.
There are grounds for my suspicion; flowering plants are proven masters of deception. For instance, the sundew uses sparkling droplets of sticky “faux dew” to ensnare and digest curious flies; bee orchids dupe male wasps into wasting their copulatory efforts on floral structures that look and smell like a female wasp. And what about humans? As I labor on behalf of flowers, fertilizing, tilling, watering and sweating, I sometimes wonder if I’m being led down the proverbial garden path. Exactly who’s cultivating whom? » Continue Reading.
Spending time in the backcountry provides many benefits, from the physical exertion of traveling through a harsh terrain to the spiritual rejuvenation that only the sounds and smells of nature can provide. One important benefit for me personally is the pleasure of being intimately immersed in the sounds of bird life, some unique to the Adirondack region.
Unfortunately, this enjoyment appears to be in jeopardy as some of the most precious Adirondack bird species are in a deadly struggle for life and death. Some of the most iconic species of the north woods appear to be losing. » Continue Reading.
Quick – which animal is most dangerous to humans in the United States? Ask State Farm, and they’ll tell you it’s the white-tailed deer, with about 150 people killed each year in auto accidents involving deer. Most lists cite mosquitoes (think West Nile), followed by bees (allergic reactions to stings), and brown recluse or black widow spiders. Domestic dogs kill about 30 people a year, horses and farm bulls about 20 each, while rattlesnakes and other venomous snakes (usually captive, handled snakes) kill about ten. If you mentioned bears, wolves or sharks, they don’t even make the list, though they always make a huge splash in the news.
Outside National Parks, bears tend to run from people, while wolves almost always flee, regardless of where you see them. Then there are moose. If moose don’t hear or smell your approach, they’re more likely to stand there, taking you in with that impassive gaze, assuming they acknowledge your presence at all. » Continue Reading.
Paul Smith’s College and TAUNY (Traditional Arts in Upstate New York) will hold a daylong festival of music, art and TED-style talks Saturday, April 26, at the Paul Smith’s College VIC.
