Dear Colleagues,

My co-authors and I are pleased to announce the publication of the
following paper:

McGovern, B., Culloch, R.M., O’Connell, M. and Berrow, S. (2016) Temporal
and spatial trends in stranding records of cetaceans on the Irish coast,
2002–2014. *Journal of the Marine Biological Association of the United
Kingdom*. pp. 1–13. doi: 10.1017/S0025315416001594


Using Irish strandings data collected between 2002 and 2014, seasonal and
annual trends in the number of strandings for all strandings identified to
species level (n = 1,480), and for the five most frequently reported
species: common dolphin (25.7% of records), harbour porpoise (22.2%),
long-finned pilot whale (8.8%), striped dolphin (6.9%) and bottlenose
dolphin (6.9%) were investigated. With the exception of bottlenose
dolphins, there was a significant linear increase in the number of
strandings across years for all species and for all strandings
collectively, that were identified to species-level. Only common dolphins
demonstrated a significant increase in the proportion of records relative
to all other strandings, which may be indicative of a real rise in the
number of strandings of this species. Common dolphins and harbour porpoises
showed a similar significant difference in monthly strandings, with more
strandings occurring during the earlier months of the year. Significant
differences in the gender of stranded animals were found in common,
striped, bottlenose and Atlantic white-sided dolphins and sperm and pygmy
sperm whales. Live and mass stranding events primarily comprised of pelagic
species. Most strandings occurred on the south and west coasts, with two
hotspots for live and mass strandings identified. The patterns and trends
identified are discussed in relation to the caveats in interpreting
strandings data. Specifically to Ireland, the findings highlight the urgent
need to build on the current volunteer reporting network and augment this
comprehensive dataset with post mortem examinations to better understand
the cause of the trends identified. The importance of strandings data in
informing conservation and management guidelines of these species’ is
