Woodcock charge deer to defend nests, footage reveals
Credit: Pixabay/CC0 Public Domain American woodcock, short, plump shorebirds with long, thin beaks, are widely known for their bobbing stride and nasally "peent" calls, but not for being aggressive. Yet one April afternoon, when a deer sniffed around a woodcock hen's ground nest looking for food, the hen lunged at it, scaring it away.

Steuerlücke Krypto: Der Staat verschenkt Milliarden
Es heißt oft, Deutschland sei ein Hochsteuerland. Doch die Frage ist: Von welchen Steuern reden wir eigentlich? Tatsächlich ist die Belastung von Arbeitseinkommen mit Blick auf die Einkommensteuer und die Sozialabgaben im internationalen Vergleich recht hoch. Schaut man hingegen auf die Besteuerung von Kapitaleinkünften, entsteht ein völlig anderes Bild.

2025 Year In Review | Stories Worth Another Read

Kelp farming is expensive, but a new resource points to lower costs
Farming kelp to sell as food, beauty products, fertilizer additives and other goods is a growing industry in Maine, but also a costly one. One key barrier for new farmers is a lack of cost-analysis tools to help reduce expenditures and develop sustainable business plans. Researchers from Kelson Marine in Portland, Maine and the University of Maine developed a new tool that provides detailed economic analyses for kelp farmers and reveals strategies for reducing the cost of farmed seaweed.
Culture is overtaking genetics in shaping human evolution, researchers argue
Researchers at the University of Maine are theorizing that human beings may be in the midst of a major evolutionary shift—driven not by genes, but by culture. In a paper published in BioScience, Timothy M. Waring, an associate professor of economics and sustainability, and Zachary T. Wood, a researcher in ecology and environmental sciences, argue that culture is overtaking genetics as the main force shaping human evolution. "Human evolution seems to be changing gears," said Waring.
Carla Kaspari: „Missstände anzuprangern, finde ich langweilig“
taz: Frau Kaspari, Sie haben ein Buch geschrieben, das im Jahr 2130 in Europa spielt. Beschreiben Sie mal in wenigen Worten die Lebensumstände, die dann herrschen.

Research team develops more holistic way to monitor lobster industry
Maine's lobster fishery—one that supports thousands of jobs statewide—is extensively monitored. Management efforts are informed by biological monitoring surveys observing changes in abundance and distribution of the lobster population, and dealer and harvester reporting from the industry. Yet these statistics don't tell the whole story of an industry shaken by supply and market disruptions and geopolitical conflict, or the welfare of the people and communities that rely on it.
Extreme climate pushed thousands of lakes in West Greenland 'across a tipping point,' study finds
West Greenland is home to tens of thousands of blue lakes that provide residents with drinking water and sequester carbon from the atmosphere. Yet after two months of record heat and precipitation in fall 2022, an estimated 7,500 lakes turned brown, began emitting carbon and decreased in water quality, according to a new study.
Bar Harbor Voters Back Strict Limits On Cruise Ship Crowds
Voters in Bar Harbor, Maine — the gateway to Acadia National Park — want stricter limits on the number of people who can disembark in town from cruise ships on a given day. A thin majority — 1,776 to 1,713 — voted not to repeal the town’s cruise ship land use ordinance, which only allows up to 1,000 people to disembark per day, and replacing it with new rules that would expand the daily cap to 3,200.
Troubled Waters: Cruise Ship Controversy Hangs Over Acadia's Gateway
The waterfront of Bar Harbor, Maine, was quiet at 7 a.m. on a warm, late-September day that saw the 1,082-foot-long Enchanted Princess, a cruise ship carrying more than 3,000 passengers, anchored in Frenchman Bay. But an hour later small boats began ferrying several dozen passengers at a time from the ship to the dock where they were greeted by a clutch of security personnel, buses, and vans that would take them around Mount Desert Island and Acadia National Park.

American lobster population and habitat preferences shifting, study finds
American lobsters along Maine's coast have relocated to new habitats, while the population simultaneously shrunk in abundance and grew older, according to a new study by University of Maine researchers. For decades, the vast majority of adult lobsters resided in boulder shelter habitats. This knowledge helped inform longtime conservation efforts and regulations within the more than $740 million fishery.
Wild Wonders Seen While Sea Kayaking In Acadia National Park
A harbor porpoise’s thin, gray dorsal fin shot through the undulating sea water less than 100 feet from my kayak off the coast of Mount Desert Island (MDI) in Maine. I spotted it while paddling along the southwestern edge of the island in late July, with a slow-moving current under my boat and cool breeze in the air.
Waters along Bar Harbor, Acadia, home to billions of microplastics
Along the shores of Acadia National Park, Bar Harbor and the Schoodic Peninsula are the vast, briny waters of Frenchman Bay. With 98 square miles of water and 39 islands, the bay is vital to shorebirds, fish, lobstermen and outdoor recreationists. University of Maine researchers, however, have discovered that Frenchman Bay and its tributaries are also home to a significant amount of microplastic pollution.
