An Intertidal Compass!

by Julia Sigwart

Dr. Julia Sigwart is an Associate Professor and the Associate Director of the Queen’s University Marine Laboratory in Northern Ireland. She is currently back home on the west coast on an extended research sabbatical at University of California, Berkeley, funded by the European Commission. Her research on the evolution of chitons and other marine creatures covers many different aspects, from fossils to neurobiology, which provides a good reason to do all sorts of fun experiments all over the world.

When you are trying to find your way home from a new place, you probably reach for your phone or GPS to ask for directions. Other animals don’t have the option of technology, but they do manage some extraordinary navigation. Birds, sea turtles, termites, and many other animals have a magnetic “sixth sense” that allows them to detect the Earth’s magnetic field, and align their direction on a migration path. This ability to sense magnetic fields, or having an “internal compass,” is termed magnetoreception.

Pioneering work on animal magnetoreception was done at Friday Harbor Labs starting in the 1980s using the seaslug Tochuina tetraquetra (formerly called Tritonia diomedea). Special equipment at FHL called a Merritt coil can manipulate electric currents to determine the force and direction of the magnetic field inside a cube that measures 6 ft on each side. This way, we can change which direction is “north” inside the experimental cube. Two members of our team, Drs Shaun Cain and Jim Murray, use this equipment for their research and for teaching a summer Neuroethology course (which will be offered again in summer 2017). In these experiments, we aimed to test for a magnetic sense in other, more primitive molluscs.

The Doris Duke Conservation Scholars Program (Apply now for 2017)

ddcsp-header

The Doris Duke Conservation Scholars Program at The University of Washington (DDCSP@UW) is now accepting applications for the 2017-2018 cohort!

About the Program

DDCSP@UW is a paid, multi-summer, undergraduate experiential learning program that explores conservation across climate, water, food and ecosystems of the Pacific Northwest.

A primary goal of the program is to expand what it means to be a “conservation professional”. By connecting conservation to cultural identity, biodiversity and environmental justice DDCSP@UW supports emerging scholars as they develop understandings, skills and perspectives needed to become a conservation change-maker.  What does this mean? Watch this video!

The first year experience begins in Seattle and travels through various cultural and ecological landscapes in Washington, from the Olympic Peninsula to the Salish Sea and across the Cascade Mountains into the Yakima Valley, learning about emerging and ongoing issues in conservation along the way. Read more about the first year “Classroom in the Field” here.


**Doris Duke Conservation Scholars will have all travel, food and lodging paid during their 8-week summer experience and will receive a stipend of $4,000 ($500/week).

Who can apply?

We’re looking for 20 freshmen and sophomores to join us for an 8-week conservation immersion course.  (*If you know of an upper-level undergraduate student, please read about other opportunities for them at the end of this email).

Scholars can be from any and all majors (including “undecided”). In fact, we’re specifically looking for a broad mix of students with varying interests, skills and perspectives who demonstrate a commitment to the environment, equity and inclusion and are curious, creative and enthusiastic. Eligible applicants must be U.S. citizen, permanent resident or have DACA status granted by the U.S. Citizenship & Immigration Services.  (For more on DACA, refer to this link).

** DDCSP@UW seeks to form and support a community of scholars who are representative of various cross-cultural backgrounds and perspectives that span across class, race, religion, ethnicity, sexual identity, sexual orientation and physical ability.

[UW Today] Ocean acidification study offers warnings for marine life, habitats

Coral ecosystems, like these pictured off the coast of Mexico, will be hit hard as the oceans become more acidic.

Coral ecosystems, like these pictured off the coast of Mexico, will be hit hard as the oceans become more acidic.

Acidification of the world’s oceans could drive a cascading loss of biodiversity in some marine habitats, according to research published Nov. 21 in Nature Climate Change.

The work by biodiversity researchers from the University of British Columbia, the University of Washington and colleagues in the U.S., Europe, Australia, Japan and China, combines dozens of existing studies to paint a more nuanced picture of the impact of ocean acidification.

While most research in the field focuses on the impact of ocean acidification on individual species, the new work predicts how acidification will affect the living habitats such as corals, seagrasses and kelp forests that form the homes of other ocean species.

“This work demonstrates the value of international collaborations to address a problem that’s global in scope and crosses boundaries between distinct habitats and ecosystems,” said co-author Terrie Klinger, professor and director of the UW’s School of Marine and Environmental Affairs who also co-directs the Washington Ocean Acidification Center. “We can begin to test predictions with data from different locations to better understand likely ecosystem responses to ocean acidification.”

[UW Today] “Our closest worm kin regrow body parts, raising hopes of regeneration in humans”

Think marine biology isn’t related to human health? Read a profile of the research done by Professor Billie Swalla and UW Biology doctoral student Shawn Luttrell on the regeneration properties of the acorn worm.

A new study of one of our closest invertebrate relatives, the acorn worm, reveals that this feat might one day be possible. Acorn worms burrow in the sand around coral reefs, but their ancestral relationship to chordates means they have a genetic makeup and body plan surprisingly similar to ours.

Marine Mammals Passive Acoustic Talk

Eavesdropping on the ocean: using passive acoustic monitoring
technologies to estimate marine mammal population sizes

Please join us for a talk by Dr. Danielle Harris on Tuesday, December
6th at 11:30am in Ocean Teaching Building room 155. Dr. Harris is a
statistical ecologist and acoustician visiting from St. Andrews
University’s Centre for Research into Ecological and Environmental
Modelling (CREEM). This lecture is open to the public.

Abstract

Population size, or abundance, estimates of many marine mammal species
are traditionally produced using data collected from visual surveys.
However, acoustic datasets can also be used to estimate abundance, and
offer a number of advantages over visual survey methods. One
advantage is that there are many instruments already deployed
worldwide for a variety of purposes, including military and seismic
monitoring, which can also be used for marine mammal surveying. In
addition, more recently developed technologies, such as underwater
gliders and other autonomous ocean vehicles, are creating new
monitoring opportunities. In this seminar, I will give an overview of
how acoustic data can be used to estimate marine mammal abundance, and highlight some of the research challenges that arise from (a) using
opportunistic data from existing instrument deployments and (b) using
new technologies. The work presented here is part of two ongoing
research projects funded by the Office of Naval Research and involves
several datasets and study species. In particular, fin whale
(Balaenoptera physalus) monitoring using Comprehensive
Nuclear-Test-Ban Treaty hydrophones in the western Pacific Ocean and
using an ocean glider to monitor cetacean species in the Southern
Californian Bight will be discussed.
