Dear all,

We are pleased to announce the publication of the following article in 
Diversity and Distributions:

Monsarrat, S., Pennino, M. G., Smith, T. D., Reeves, R. R., Meynard, C. N., 
Kaplan, D. M., & Rodrigues, A. S. (2015). Historical summer distribution of the 
endangered North Atlantic right whale (Eubalaena glacialis): a hypothesis based 
on environmental preferences of a congeneric species. Diversity and 
Distributions.


Abstract
Aim

To obtain a plausible hypothesis for the historical distribution of North 
Atlantic right whales (NARWs) (Eubalaena glacialis) in their summer feeding 
grounds. Previously widespread in the North Atlantic, after centuries of 
hunting, these whales survive as a small population off eastern North America. 
Because their exploitation began before formal records started, information 
about their historical distribution is fragmentary.


Location

North Atlantic and North Pacific oceans.

Methods

We linked historical records of North Pacific right whales (E. japonica; from 
19th-century American whaling logbooks) with oceanographic data to generate a 
species distribution model. Assuming that the two species have similar 
environmental preferences, the model was projected into the North Atlantic to 
predict environmental suitability for NARWs. The reliability of these 
predictions was assessed by comparing the model results with historical and 
recent records in the North Atlantic.



Results

The model predicts suitable environmental conditions over a wide, mostly 
offshore band across the North Atlantic. Predictions are well supported by 
historical and recent records, but discrepancies in some areas indicate lower 
discriminative ability in coastal, shallow-depth areas, suggesting that this 
model mainly describes the summer offshore distribution of right whales.

Main conclusions

Our results suggest that the summer range of the NARW consisted of a relatively 
narrow band (width c. 10° in latitude), extending from the eastern coast of 
North America to northern Norway, over the Grand Banks of Newfoundland, south 
of Greenland and Iceland, north of the British Isles and in the Norwegian Sea. 
These results highlight possibilities for additional research both on the 
history of exploitation and on the current summer distribution of this species. 
In particular, better survey coverage of historical whaling grounds could help 
inform conservation efforts for this endangered species. More generally, this 
study illustrates the challenges and opportunities in using historical data to 
understand the original distribution of highly depleted species.
