My scientific interests veer towards ecology and evolution. I've done shorebird conservation work on the Maine coast, seabird trophic interaction research on the Oregon coast, and leaf-cutter ant distribution research in the Costa Rican rainforest. I also have strong feelings for paleoecology and paleoclimateology. Some questions I often ponder: How can the scientific community make actual progress? Is science really objective? Is the work I'm doing actually productive for society? Feel free to drop me a line at culturingscience [at] gmail [dot] com

Swarms of tasty cicadas don’t help the birds — what gives?

by Hannah Waters in Culturing Science – biology as relevant to us earthly beings

Every thirteen years they come. After over a decade underground, they build burrows to the earth’s surface and emerge in synchrony, clawing and crawling up through the soil, rip their skins down the back and are reborn as adults. And after a month, they will be dead, whether consumed by the animals awaiting their arrival [...]... Read more »

Natural history collections in ecological research

by Hannah Waters in Culturing Science – biology as relevant to us earthly beings

Once I dreamed a dream of being an evolutionary biologist.  As I imagined it, I would hang out in a natural history museum, comparing fossils to one another, taking notes on the minute differences, and piecing together the history of life. It wasn’t until a job fair years ago, when I babbled to an evolutionary [...]... Read more »

The many relationships of leaf-cutter ants

by Hannah Waters in Culturing Science – biology as relevant to us earthly beings

Trying to capture the movement of a colony of leaf-cutter ants in a single photo is nearly impossible in my (amateur) experience.  The queues of ants follow a worn-down trail in the ground that they themselves made with the impact of their little ant feet.  There are ants moving in both directions, between the food [...]...

Self-Help for Seabirds: How to manage your time and outcompete your neighbors for maximum survival

by Hannah Waters in Sleeping with the Fishes

Last night was my first night in NYC and, as such, it was my first experience with modern-day human foraging: the Trader Joes in Chelsea at 7:30 pm.  Despite the many shelves previously stuffed with various types of bagged lettuce, there was NO LETTUCE LEFT.  No granola bars.  The customers were nasty, ramming their carts into me to get to the dried cranberries.  While sometimes I’ve been to groceries that have been out of a particular item I wanted, I have never thought to myself, &#........

When adaptation doesn’t happen

by Hannah Waters in Culturing Science – biology as relevant to us earthly beings

How clownfish help their anemones: nutrient transfer in a triple symbiosis

by Hannah Waters in Sleeping with the Fishes

The vision of a tropical beach is something we take for granted: the white sands, crystal blue water, and colorful, diverse reefs.  It’s like a playground designed just for us where everything is beautiful and comfortable (well, minus the sunburn).  But we actually shouldn’t take this for granted, as the existence of coral reefs in warm tropical waters is not a give-in, but rather the result of millions of years of slow evolution and coevolution to cope with this nutrient-poor ha........

Coddle me, please: parallel evolution and fishery management in Atlantic cod

by Hannah Waters in Sleeping with the Fishes

Historically, perhaps due to human interest in maximizing fishing activity, we have assumed that there is a great deal of gene flow in marine populations.  This assumption allowed us to maximize fishing efforts without guilt, since a large, ocean-wide population would allow fish from other parts of the world to refill populations that we had reduced by overfishing.  But you know what they say about assumptions: they make an ASS out of U and ME.  Thus marine biologists have taken an interest ........

If you feed them, they will come: the effects of nitrogen fertilization on community composition in a salt marsh

by Hannah Waters in Culturing Science – biology as relevant to us earthly beings

Eutrophication has gained a pretty bad reputation considering that it is a natural process.  The word itself comes from the Greek “eutrophia” which means “healthy” and simply means the addition of nutrients into an ecosystem encouraging plant growth.  Of course, … Continue reading →... Read more »

The grand diversity of marine phytoplankton species: focusing from space

by Hannah Waters in Sleeping with the Fishes

In a recent email exchange with a (skeptically) wonderful blogger about why we are interested in what we are and where past/current biases lie, I wrote that I “grew up wanting to look at the planet from space.”  This is true in multiple senses: my drive to seek patterns in collected studies and data, and also my interest in large-scale ecology generally. But, of course, we can actually look at the planet from space!  And collect data at the same time!  Via the wonder of SATELLIT........ Read more »

Seabirds as indicators of marine ecosystem health: an introduction

by Hannah Waters in Sleeping with the Fishes

The primary reason for studying marine ecology is for ecosystem and resource management.  Over half of the human population lives in the coastal zone, and we all are dependent on the ocean, either for food resources of simply because phytoplankton are responsible for the production of nearly half of atmospheric oxygen.  Add to that the great biodiversity of marine life and its sheer beauty… and we have a resource that we should all be dedicated to conserving and protecting.

Can seabirds overfish a resource? The case of cormorants in Estonia

by Hannah Waters in Culturing Science – biology as relevant to us earthly beings

How did they get there? The colonization of a hydrothermal vent after volcanic eruption

by Hannah Waters in Culturing Science – biology as relevant to us earthly beings

To some people, a volcanic eruption means “Ahh!  Run!  Hot Lava!”  But to others, it means “SCIENCE!”  To those studying hydrothermal vent communities, that is (and a wide berth of geologists). Hydrothermal vents are cracks in the seafloor formed when tectonic plates spread apart, which spew out hot, mineral-rich water from the interior of the [...]... Read more »
