Dear  MARMAM Colleagues,


My co-authors and I are pleased to announce the publication of the
following article in the Journal of  Mitochondrial DNA Part A :Arsalan Emami-Khoyi, Adrian M. Paterson, David A. Hartley, Laura
J. Boren, Robert H. Cruickshank, James G. Ross, Elaine C. Murphy &
Terry-Ann Else*Mitogenomics data reveal effective population size, historical
bottlenecks, and the effects of hunting on New Zealand fur seals
(Arctocephalus forsteri)**Abstract :*


The New Zealand fur seal (Arctocephalus forsteri) passed through a
population bottleneck due to com- mercial sealing during the eighteenth
to nineteenth centuries. To facilitate future management options, we
reconstructed the demographic history of New Zealand fur seals in a
Bayesian framework using maternally inherited, mitochondrial DNA
sequences. Mitogenomic data suggested two separate clades (most recent
common ancestor 5000 years ago) of New Zealand fur seals that survived
large-scale human harvest. Mitochondrial haplotype diversity was high,
with 45 singletons identified from 46 indi- viduals although mean
nucleotide diversity was low (0.012 ± 0.0061). Variation was not
constrained geo- graphically. Analyses of mitogenomes support the
hypothesis for a population bottleneck approximately 35 generations ago,
which coincides with the peak of commercial sealing. Mitogenomic data
are consistent with a pre-human effective population size of
approximately 30,000 that first declined to around 10,000 (due to the
impact of Polynesian colonization, particularly in the first 100 years
of their arrival into New Zealand), and then to 100–200 breeding
individuals during peak of commercial sealing.The full text is available at  the following address or upon direct
