Abstract: The skin is the first line of defense between an animal
and its environment, and disruptions in skin-associated
microorganisms can be linked to an animal's health and nutritional
state. To better understand the skin microbiome of large whales,
high-throughput sequencing of partial small subunit rRNA genes was
used to study the skin-associated bacteria of 89 seemingly healthy
humpback whales (Megaptera novaeangliae) sampled along
the Western Antarctic Peninsula (WAP) during early (2010) and late
(2013) austral summers. Six core groups of bacteria were present in
93% or more of all humpback skin samples. A shift was observed in
the average relative abundances of these core bacteria over time,
with the emergence of four additional core groups of bacteria that
corresponded to a decrease in water temperature, possibly caused by
season- or foraging-related changes in skin biochemistry that
influenced microbial growth, or other temporal factors. The skin
microbiome differed between whales sampled at several regional
locations along the WAP, suggesting that environmental factors or
population may also influence the whale skin microbiome. Overall,
the skin microbiome of humpback whales appears to provide insight
into animal- and environment-related factors and may serve as a
useful indicator for animal health or ecosystem alterations.
Feel free to reach out to me or the co-authors with questions.
