One Species at a Time Podcast Series: Monarch Butterflies

Every year, monarch butterflies begin a journey north from their overwintering grounds in Mexican forests. The epic migration spans generations and the better part of a continent. In this first of two episodes, we'll meet a pair of women united by their fascination with this iconic insect. Mexican geographer Isabel Ramirez and American biologist Karen Oberhauser are working to save monarch habitat on both ends of this remarkable insect's 2,500 mile journey. Encyclopedia of Life

Cormorants and the culture that wants them dead

When should nature be left to take its course? That's a question that may surface with yesterday's announcement that the Minnesota Department of Natural Resources is going to "control" cormorants on Lake Vermilion. Linda Wires, a research fellow at the University of Minnesota's Dept. of Fisheries, Wildlife & Conservation Biology, responds. Minnesota Public Radio

Monarch butterflies navigate with compass but no map

A study that aims to answer the question of how monarch butterflies make their way to Mexico each year has generated pushback from outside researchers who question the study’s key claim: that monarch butterflies can stick only to a direction that is biologically predetermined, but are unable to change it if blown off course. Karen Oberhauser, a monarch expert at the University of Minnesota, noted that the authors did not test which navigation system was a better fit for the tagging data.

Asian carp in Minnesota? If you net one, yes. But DNA won't tell.
Were the Asian carp here or weren't they? In 2011, alarms rang as researchers reported finding signs of silver carp well into Minnesota waters...."EDNA would be a bad way to tell a chimp from a human being, without sequencing," said Peter Sorensen, director of the Aquatic Invasive Species Research Center at the University of Minnesota and one of the organizers of the new study. Pioneer Press

Dr. Susan M. Galatowitsch awarded the 2013 R1Edu Award

CFANS faculty member Dr. Susan M. Galatowitsch (Dept. Head, Department of Fisheries, Wildlife, and Conservation Biology) has won the 2013 R1Edu award for excellence and innovation in online learning for her work in developing a series of ecological restoration online training courses.

The groundbreaking five-course series, based on Dr. Galatowitsch's work, is the foundation for the Ecological Restoration Training Cooperative, and is sponsored by the College of Continuing Education and CFANS. 

Although ecological restoration has been pursued for more than 50 years in the U.S., very little is known about how to restore most ecosystems so they resemble natural (i.e., not previously converted) ones. In addition, up to this point, this type of restoration has been guided primarily by minimizing time and costs, rather than by an understanding of ecological processes.

Professor Galatowitsch's address those issues by bringing scientific knowledge and a longer-term perspective to the important task of ecological restoration carried out by restoration professionals throughout the state and the region, and potentially across the nation.

Few, if any, Asian carp in St. Croix, Mississippi rivers

The long-feared Minnesota invasion of two species of invasive carp apparently has not hit yet. No DNA of silver and bighead carp, often referred to as Asian carp, was detected in the Mississippi or St. Croix rivers in Minnesota, according to a fresh analysis by federal, state and academic researchers, officials announced Thursday. The new study was led by the Minnesota Aquatic Invasive Species Research Center and its director, Peter Sorensen. MPR News

Global warming proves helpful for penguins

A recent study found that over the last 60 years, a colony of the birds on Beaufort Island in the Ross Sea, south of New Zealand, increased by 84 percent, from 35,000 breeding pairs to 64,000 breeding pairs. This increase has come as glaciers have retreated from the island, leaving more bare, snow-free ground, where the penguins make their nests.

Long cloaked in mystery, Owls start coming into their own

Owls are a staple of children's books and cultural kitsch, and only lately scientists have begun to understand the birds in any detail, and to puzzle out the subtleties of behavior, biology and sensory prowess that set them apart from all other avian tribes. Other researchers are tracking the lives of some of the rarer and more outlandishly proportioned owls, like the endangered Blakiston’s fish owl of Eurasia. Nearly a yard high, weighing up to 10 pounds and with a wingspan of six feet, Blakiston’s is the world’s largest owl, a bird so hulking it’s often mistaken for other things, according to Jonathan Slaght (former grad student advised by Francie Cuthbert (M.S.) and Rocky Gutierrez (Ph.D.) of the Wildlife Conservation Society’s Russia program. It could easily look like a bear in a tree or a man on a bridge. The New York Times

The effect of outdoor cats on bird and mammal mortality

(Washington, D.C., January 29, 2013) A new peer-reviewed study published today and authored by scientists from two of the world’s leading science and wildlife organizations – the Smithsonian Conservation Biology Institute and the U.S. Fish and Wildlife Service (FWS) – has found that bird and mammal mortality caused by outdoor cats is much higher than has been widely reported, with annual bird mortality now estimated to be 1.4 to 3.7 billion and mammal mortality likely 6.9 – 20.7 billion individuals.The study, which offers the most comprehensive analysis of information on the issue of outdoor cat predation, was published in the online research journal Nature Communications and is based on a review of 90 previous studies. The study was authored by Dr. Peter Marra and Scott Loss, research scientists at the Smithsonian Conservation Biology Institute and by Tom Will from the U.S. Fish and Wildlife Service’s Division of Migratory Birds. Scott earned his PhD in Conservation Biology, advised by Rob Blair.

A new tool targeting Asian Carp?

By most measures, Eden Prairie’s Staring Lake is a dead lake – native game fish have been crowded out by an overabundance of common carp. Now, those fish have become the guinea pigs in a research project aimed at controlling their leaping cousins.“The big issue with Asian carp is that we don’t know how many there are, or where they are,” explains University of Minnesota fisheries researcher Peter Sorensen.

Expectations and issues ahead for hunters and fishers in '13

Minnesota's battle to stop the spread of invasive species such as zebra mussels and Asian carp will be ramped up in 2013 -- and that fight will affect the state's estimated 2.3 million boaters. For the first time, the DNR launched random roadside checks of boaters in 2012. But just nine check stations were conducted involving 140 boaters. (The violation rate: 31 percent.) This year, DNR officials plan to boost the number of roadside checks, and will try some in busier areas they avoided last year. Meanwhile, the new Aquatic Invasive Species Research Center at the University of Minnesota will be up and running in 2013 -- but don't expect any silver bullets soon. Star Tribune

Black bear: Medical Marvel

Bears can go four to six months without eating or activity and wake up ready to run. How do they do it, and what if their secret could be translated to hospital patients? Such questions have led Paul Iaizzo, U of M Professor of Surgery, from his lab in Minneapolis to bear dens in Colorado, Wyoming, and northern Minnesota.The project has since expanded into an annual collaboration that includes work in northern Minnesota with University adjunct professor Dave Garshelis, Ph.D., a world-renowned bear researcher with the Minnesota Department of Natural Resources.

Beware of otter: Two more take bites out of St. Michael swimmer

Forget pesky mosquitoes or black bears. It's angry otters that are chasing visitors out of the woods in northern Minnesota. In less than a month, unusually aggressive otters have attacked two Twin Cities women swimming in lakes about 60 miles apart. They're two of the three attacks reported to the state in the past three months, puzzling experts who say otters are generally meek, playful creatures. ...They usually eat fish and clams and breed in the spring, which is why University of Minnesota Prof. James David Smith surmises the otters were protecting nearby pups. "I think it's just a rare event," he said, adding that people are more likely to run into a black bear or mountain lion. Star Tribune

U research center could help make it a fairer fight

No one can accuse Peter Sorensen of being timid. He proposed a world-class invasive species research center at the University of Minnesota to fight zebra mussels, Asian carp and other critters that have invaded and threaten Minnesota waters.

Minnesota should care more about its own ducks

Whether waterfowl manager is a scientific occupation or one devoted instead largely to cheerleading is a fair question now that the U.S. Fish and Wildlife Service has reported "record" numbers of ducks on the continent. Perhaps the service's estimated increase to 48.6 million ducks from last year's 45.6 million is accurate, perhaps not. Either way, it shouldn't affect duck-starved Minnesota, where wildlife managers in recent years have been busy trying to help hunters shoot their way back to waterfowling prosperity....

Keeping monarchs on the move

(Apr. 2011) Like many human retirees, some monarch butterflies have taken up residence in Florida, where they need not migrate to find winter warmth. Cushy as that life may seem, however, the Florida populations would probably enjoy better health if, like their northern cousins, they flew 1,500 miles south into central Mexico for the winter.In a new study, University of Minnesota monarch researcher Karen Oberhauser and three colleagues showed that long migrations tend to rid butterfly populations of parasites. This implies that disruptions to migrations, whether by habitat loss, loss of nectar plants along the migration route, climate change, or other factors, can reduce the fitness of monarchs, other migrating insects, and even vertebrates.
