In their quest to understand what kind of hunter the extinct marsupial thylacine was, two paleobiologists built a dataset of forelimb bone measurements that predict the predation style of a wide variety of carnivorous mammals. They describe the data in a study posted online in the Journal of Morphology.

PROVIDENCE, R.I. [Brown University] — At the start of their research, paleobiologists Christine Janis and Borja Figueirido simply wanted to determine the hunting style of an extinct marsupial called thylacine (also known as the “marsupial wolf” or the “Tasmanian tiger”). In the end, the Australian relic, which has a very dog-like head but both cat- and dog-like features in the skeleton, proved to be uniquely unspecialized, but what emerged from the effort is a new classification system that can capably predict the hunting behaviors of mammals from measurements of just a few forelimb bones.

New Study Reconstructs the Past Ocean ‘Paleome’

When Woods Hole Oceanographic Institution (WHOI) marine paleoecologist Marco Coolen was mining through vast amounts of genetic data from the Black Sea sediment record, he was amazed about the variety of past plankton species that left behind their genetic makeup (i.e., the plankton paleome).

The semi-isolated Black Sea is highly sensitive to climate driven environmental changes, and the underlying sediments represent high-resolution archives of past continental climate and concurrent hydrologic changes in the basin. The brackish Black Sea is currently receiving salty Mediterranean waters via the narrow Strait of Bosphorus as well as freshwater from rivers and via precipitation. (more…)

New Mobile App Helps Migraine Sufferers Track and Analyze Pain

ANN ARBOR — A new iPhone app developed at the University of Michigan lets migraine or facial pain patients easily track and record their pain, which in turn helps the treating clinician develop a pain management plan.

Dr. Alexandre DaSilva, director of the Headache & Orofacial Pain Effort (H.O.P.E.) at the U-M School of Dentistry and one of the project developers, said the app will help people with migraine, temporomandibular disorders (TMD) and other types of facial nerve pain. (more…)

Fingerprints for Financing: Removing Some Risk from Lending in Africa

ANN ARBOR — Some called it “witchcraft.” Others just watched in awe as their scanned fingerprints were used to pull up their records on a computer.

They were paprika farmers in Malawi participating in a new study that shows fingerprinting can help encourage borrowers to repay their loans.

Like many impoverished countries, Malawi lacks a national identification system. Most of the population lives in rural areas with few government services. Even ID as basic as a birth certificate is rare in the southeastern African nation. (more…)

Ear-bone ‘tree rings’ provide evidence of connectivity

Ocean scientists have long known that juvenile coral reef fishes use coastal seagrass and mangrove habitats as nurseries, later moving as adults onto coral reefs. But the fishes’ movements, and the connections between different tropical habitats, are much more complex than previously realized, according to a study published September 3 in Proceedings of the National Academy of Sciences. The findings have important implications for management and protection of coral reefs and other marine environments.

A number of studies have demonstrated a strong relationship between the presence of coastal wetlands and offshore fish abundance and fisheries yield, but it has proved difficult to develop quantitative assessment of habitat use by fish or their movement among different habitats. “The rationale for this study,”says Simon Thorrold, a biologist at Woods Hole Oceanographic Institution (WHOI), “was to determine the relative importance of different nursery habitats to reef fishes that spend their adult lives on coral reefs but may spend at least part of their juvenile residency elsewhere.” (more…)

Back to the Future: A New Science for a Changing Planet

In a world that is changing on a global scale and faster than ever before, science should rediscover its roots of observing the natural world unimpeded by the strict protocols of experimental manipulations, UA ecologist Rafe Sagarin and co-author Aníbal Pauchard suggest in their book, “Observation and Ecology.”

Mars rover Curiosity is doing it. School children strolling through the woods with binoculars are doing it. Charles Darwin was doing it. Observing the natural world around them was how the early naturalists started what would later become known as ecology – the science of how living things interact, depend on each other and how their habitats and communities change over time.

In their book, “Observation and Ecology,” ecologists Rafe Sagarin and Aníbal Pauchard make the case that if scientists are to tackle the enormously complex problems the world is facing, researchers and funding agencies have to leave their comfort zone of well-controlled experimental manipulations.
