A major challenge in conservation biology is the need to broadly
prioritize conservation efforts when demographic data are limited. One
method to address this challenge is to use population genetic data to
define groups of populations linked by migration and then use demographic
information from monitored populations to draw inferences about the status
of unmonitored populations within those groups. We applied this method to
anadromous alewife (Alosa pseudoharengus) and blueback herring (Alosa
aestivalis), species for which long-term demographic data are limited.
Recent decades have seen dramatic declines in these species, which are an
important ecological component of coastal ecosystems and once represented
an important fishery resource. Results show that most populations comprise
genetically distinguishable units, which are nested geographically within
genetically distinct clusters or stocks. We identified three distinct
stocks in alewife and four stocks in blueback herring. Analysis of
available time series data for spawning adult abundance and body size
indicate declines across the US ranges of both species, with the most
severe declines having occurred for populations belonging to the Southern
New England and the Mid-Atlantic Stocks. While all alewife and blueback
herring populations deserve conservation attention, those belonging to
these genetic stocks warrant the highest conservation prioritization.
