About Stacy Krueger-Hadfield

I am a marine evolutionary ecologist interested in the impacts of seascapes and complex life cycles on marine population dynamics. I use natural history, manipulative field experiments and population genetic and genomic approaches with algal and invertebrate models in temperate rocky shores,estuaries and the open ocean.

What do dolphins, bivalves and algae have in common?

Collaboration as it turns out, between three scientists interested in vertebrates, invertebrates and algae! A few days before we left for Evolution 2016 in Austin, one of my collaborators, Eric Pante, came to Charleston as the final stop in a North American … Continue reading

Personal narrative of a journey from zoos to academia

Back in February, the South Carolina Aquarium and The Center for Humans and Nature hosted the finale in the Holland Lifelong Learning series of “Why do zoos and aquariums matter?” in Charleston. I’ll admit, at first, the main reason I … Continue reading

The not so singular process of hybridization

What, if anything, are hybrids? Zach Gompert and Alex Buerkle ask this question in a special issue in Evolutionary Applications. Hybrids occur when unrelated individuals mate, but how distant do the taxa need to be to constitute a cross? The varied … Continue reading

Signatures of the reproductive lottery

In marine populations, effective population sizes are usually several orders of magnitude lower than the census size. This difference is thought to be driven by high fecundity, variation in reproductive success and pronounced early mortality, resulting in genetic drift across generations. In … Continue reading

Neglected mycoplankton, no more

Taylor and Cunliffe (2016) provide a window into the world of the plankton in which they focus on a rarely studied component, the planktonic fungi (mycoplankton). Marine mycoplankton exist as free-living filamentous and yeast forms or as parasite of other … Continue reading

What makes a range?

Why do species have restricted geographic distributions? Classic ecological perspectives tell us distribution limits occur where ecological parameters coincide with the boundaries of ecological niches. Evolutionary perspectives, on the other hand, surmise distribution boundaries reflect a failure of niche evolution. Though small … Continue reading

Coral clonal chimeras

We are all too aware of the threats ecosystem engineers, such as corals, face in light of global climate change. However, a new study by Rinkevich et al. (2016) suggest chimerism may be a a weapon to combat climate change. … Continue reading

There and back again: an angiosperm’s tale

Eelgrass (Zostera marina) is the dominant seagrass in the northern hemisphere and provides the foundation of highly productive ecosystems that rival tropical rain forests and coral reefs in ecosystem services. Zostera isn’t really a grass, but a monocot, like a … Continue reading

A race to the bottom with a new card from the coevolutionary deck

I’m a sucker for a clever, amusing title, though I’ve recently read that amusing titles are cited less (see here). Alas, maybe a well placed metaphor can enliven a manuscript and also not get lost in a citation-less abyss? In basic … Continue reading

Macroalgal miscellany

It’s been a jam-packed week and I’ve found myself at Friday. Grandiose plans for a post continuing the series on clonality (see here and here) did not come to fruition. But, I was saved with a new article that tumbled … Continue reading
