EAST LANSING, Mich. — Browning shoots and needles, twisting and stunted shoots – especially near the tops of evergreen trees and shrubs – are signs that plants may have injuries associated with the herbicide Imprelis, according to a Michigan State University researcher.(more…)
*Research Bolsters Importance of Horseshoe Crab Spawning for Migrating Shorebirds*
LAUREL, Md. – Speculation that the welfare of a small, at-risk shorebird is directly tied to horseshoe crab populations is in part supported by new scientific research, according to a U.S. Geological Survey- led study published in Ecosphere, a journal of the Ecological Society of America.
Population health of the red knot, a shorebird species whose population has plummeted over the last 15 years, has been directly tied to the number of egg-laying horseshoe crabs in Delaware Bay — between Delaware and New Jersey — during the red knot’s northward migration each spring. (more…)
The size of leaves can vary by a factor of 1,000 across plant species, but until now, the reason why has remained a mystery. A new study by an international team of scientists led by UCLA life scientists goes a long way toward solving it.(more…)
RIVERSIDE, Calif. – A new study shows that the desert tortoise, thought to be one species for the past 150 years, now includes two separate and distinct species, based on DNA evidence and biological and geographical distinctions.
This genetic evidence confirms previous suspicions, based on life history analysis, that tortoises west and east of the Colorado River are two separate species. (more…)
Recovered by recreational fishermen who found the creature floating on the surface about 12 miles offshore from Jensen Beach Sunday, museum scientists collected the specimen from the Florida Fish and Wildlife Conservation Commission Tequesta Field Laboratory in Palm Beach County and returned to the Gainesville campus late Monday.

ANN ARBOR, Mich.— This year marks a full century that instructors at the University of Michigan Biological Station on Douglas Lake near Pellston have been teaching students about northern Michigan’s birds. The station was established in 1909, and two years later a course titled “The Natural History of Birds” first appeared in the summer bulletin.(more…)
*A University of Exeter biologist has discovered a ‘lost’ species of bat breeding on the Isles of Scilly.*
*A pregnant female brown long-eared bat is the first of its species to be found on the islands for at least 40 years.*
It was discovered by Dr Fiona Mathews, Senior Lecturer at the University of Exeter, a postgraduate student and a team from the Wiltshire Bat Group.
The Scilly Isles Bat Group called in Dr Mathews and her team to help them find out more about bats on the islands. The researchers set up a radiotracking study, with funding from the Isles of Scilly Area of Outstanding Natural Beauty, to monitor the islands’ bat activity. (more…)
*High-mountain wildflower season reduced, affecting pollinators like bees, hummingbirds*
It’s summer wildflower season in the Rocky Mountains, a time when high-peaks meadows are dotted with riotous color.
But for how long?
Once, wildflower season in montane meadow ecosystems extended throughout the summer months. But now scientists have found a fall-off in wildflowers at mid-season. (more…)
