The Polar Linkage Express: complicated interactions between the Arctic and mid-latitudes

Climb aboard the Polar Linkage Express to learn about the main challenges facing scientists as they try to decipher just what is going on with winter weather these days! Is it really linked to the state of the Arctic?

With A Little Help From My Friend: Unexpected benefits of invasive species?

Invasive species are widely talked about as unequivocally bad influences on ecosystems, but oftentimes their interactions are more complex. Click here to read more about an unexpected interplay between two mussel species in the intertidal zone!

Oil rigs, the food trucks of the sea?

We humans don’t always take time to assess how we impact other environments; more often we survey before we enter the ecosystem, but what happens when we leave? Oil rigs in the North Sea have provided a great opportunity for scientists to start investigating. Click here to find out more!

Listening for Symptoms: A new use for hydrophones in the face of harmful algal blooms

Whales aren’t the only animals hydrophones can detect out in the ocean. In fact, in the near future it might be possible to listen in on animals like scallops and determine if they’re healthy or not. Intrigued? Click here for more!

Do You Have Your Exit Buddy?

It’s a tough ocean out there for a larval fish—sticking together can be the best thing to do. But until now, we didn’t know how beneficial schooling could be. Intrigued? Click here to find out more!

Light on the Tree of Life: Evolution of Bioluminescence

The darkness can be scary sometimes–but that’s when evolution can get pretty crazy in its adaptations. Meet some of the fishes that can glow in the dark and learn about how many times this special ability evolved–it’s certainly surprised many scientists in the community!

Bringing Down the Fever: Sea Star Wasting Disease

Sea stars have been wasting away–literally! Outbreaks of this poorly understood disease have been noticed many times in the last century, and now, a new study has come out trying to understand the potential for sea stars to survive this threat. Intrigued? Click here to read more!

Going Mute: Ocean acidification silences shrimp snaps

Coastal areas could fall silent in the next century as ocean acidification alters and affects the natural soundscapes of the oceans. Intrigued? Click here to read more!

Summiting Sand Dune Crests: A challenge of restoration

With spring break upon us, we’re all looking for a way to unwind and have fun. For some areas relying on tourism for economic stability, though, fragile habitats can often be overlooked in an effort to keep money flowing in. Click here to find out more about new research being conducted on restoring one of Brazil’s vulnerable microbiomes: sand dunes.

The Search for Dolly Varden

A fish that has contributed greatly to subsistence farming in Alaska might face negative impacts of human development and become the victim of a misunderstanding for the second time in as many centuries. Click here to find out more!

Making Room for New Neighbors: Observing Penguin Foraging

What happens when we rely on models, only to realize we’re missing pieces of the puzzle? Climate change models predict Adélie penguins will face increased resource competition from other penguin species, but new evidence indicates modifying behavior might take some pressure off these flightless birds.

A Snack That’s Literally On the House?

Most important relationships have deep running roots, not always visible to the world. It turns out, some symbiotic or mutualistic associations in nature have more layers to them than meets the eye. Case in point: the clownfish and the anemone. Intrigued? Click here to read more!

Young sharks might assess habitats differently than first assumed

What if prey abundance and fewer predators are not the only things driving young sharks to seek out coastal areas as they grow older? What if it is something in the water itself? Click here to find out how abiotic factors could aid in sharks’ habitat selection choice.

By the Light of the Night: Abiotic factors limit Arctic seabird foraging

Understanding how species interact with prey has often led scientists to only consider biological connections. But what if the environment itself alters how efficient predators can be? That may be the case for the thick-billed murre. Click here to find out more!

Decalcifying Calcidiscus: An effect of ocean acidification on plankton

The vastness of the ocean can be deceptive–you’d think that only big things would have an impact on something the size of an ocean. That’s not always the case, though. Sometimes the smallest organisms can influence huge, global processes. But one such small organism is faced with harsher conditions these days and isn’t faring too well. Read more to find out!
