Dear MARMAM community,

My co-authors and I are pleased to announce and share our new paper:

“The Southern Ocean Exchange: porous boundaries between humpback whale
breeding populations in southern polar waters”, which has been
published in *Scientific


Humpback whales (*Megaptera novaeangliae*) are a cosmopolitan species and
perform long annual migrations between low-latitude breeding areas and
high-latitude feeding areas. Their breeding populations appear to be
spatially and genetically segregated due to long-term, maternally inherited
fidelity to natal breeding areas. In the Southern Hemisphere, some humpback
whale breeding populations mix in Southern Ocean waters in summer, but very
little movement between Pacific and Atlantic waters has been identified to
date, suggesting these waters constituted an oceanic boundary between
genetically distinct populations. Here, we present new evidence of summer
co-occurrence in the West Antarctic Peninsula feeding area of two
recovering humpback whale breeding populations from the Atlantic (Brazil)
and Pacific (Central and South America). As humpback whale populations
recover, observations like this point to the need to revise our perceptions
of boundaries between stocks, particularly on high latitude feeding
grounds. We suggest that this “Southern Ocean Exchange” may become more
frequent as populations recover from commercial whaling and climate change
modifies environmental dynamics and humpback whale prey availability.

Please find it freely available online at www.nature.com/articles/

On behalf of my co-authors, I thank you for the interest in our research.
