The North Atlantic right whale (NARW) (Eubalaena glacialis) is one of the world's most threatened whales. It came close to extinction after nearly a millennium of exploitation and currently persists as a population of only approximately 500 individuals. Setting appropriate conservation targets for this species requires an understanding of its historical population size, as a baseline for measuring levels of depletion and progress toward recovery. This is made difficult by the scarcity of… 

The recovery of North Atlantic right whales, Eubalaena glacialis, has been constrained by human-caused mortality

A population projection model for female NARW indicated an intrinsic rate of increase of 4% per year, approximately twice that observed, and that adult female mortality is the main factor influencing this rate.

Phenological changes in North Atlantic right whale habitat use in Massachusetts Bay

The value of continuous long- term survey datasets to detect and quantify shifts in cetacean habitat use as environmental conditions change and the long-term continued survival of right whales remains uncertain is demonstrated.

This work reconstructed the South Georgia fur seal harvest from 1786 to 1908 from ship logbooks and other historical records and interpolated missing harvest data as necessary with a generalized linear model fit to the historical record, and estimated the pre-exploitation abundance of Antarctic fur seals on South Georgia was 2.5 million females.

Forgotten Mediterranean calving grounds of grey and North Atlantic right whales: evidence from Roman archaeological records

The evidence that these two coastal and highly accessible species were present along the shores of the Roman Empire raises the hypothesis that they may have formed the basis of a forgotten whaling industry, and significantly extend the known range of the Atlantic grey whale.

Collateral damage to marine and terrestrial ecosystems from Yankee whaling in the 19th century

The “collateral damage,” the opportunistic or targeted taking of nongreat whale species by the American whaling industry is described and the ecosystem impacts of whaling reverberated on both marine and coastal environments.

Endangered Right Whales Enhance Primary Productivity in the Bay of Fundy

The results of this study support the idea that the distinctive isotopic signature of the released NH4+ could be used to provide a conservative estimate of the contribution of the whale pump to primary productivity in coastal regions where whales congregate.

Whaling tradition along the Cantabrian coast: public perception towards cetaceans and its importance for marine conservation

Whaling is currently a controversial practice and the focus of a relevant public debate. According to records, it represented an important socio-economic activity in the North of Spain from the

Using historical and palaeoecological data to inform ambitious species recovery targets

The case for why setting species recovery against a historical baseline is necessary to produce ambitious conservation targets is presented, and examples from palaeoecology and historical ecology where fossil and archival data have been used to establish historical species baselines are highlighted.



Insights into North Pacific right whale Eubalaena japonica habitat from historic whaling records

Tests of model performance at different scales strongly suggest that at the basin-scale, right whales use regions of cold water with low inter-annual variability and high within-season variability (i.e. areas where high frontal activity occurs predictably from year to year).

Climate and the conservation biology of North Atlantic right whales: the right whale at the wrong time?

Demographic projections predict that the North Atlantic right whale population will become extinct in less than 200 years, and extrapolations suggest that reducing mortality rates by a few female deaths per year through conservation efforts would support a slow recovery of the population.

History of Whaling and Estimated Kill of Right Whales, Balaena glacialis, in the Northeastern United States, 1620–1924

This study, part of a broader investigation of the history of exploitation of right whales, Balaena glacialis, in the western North Atlantic, emphasizes U.S. shore whaling from Maine to Delaware

Right Whales: Eubalaena glacialis, E. japonica, and E. australis

Historical summer distribution of the endangered North Atlantic right whale (Eubalaena glacialis): a hypothesis based on environmental preferences of a congeneric species

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

Utility of North Atlantic Right Whale Museum Specimens for Assessing Changes in Genetic Diversity

Abstract: We examined six historical specimens of the endangered North Atlantic right whale (Eubalaena glacialis) using DNA isolated from documented baleen plates from the late nineteenth and early

DNA evidence for historic population size and past ecosystem impacts of gray whales

A genetic approach to estimate prewhaling abundance of gray whales is used and levels of genetic variation suggest the eastern population is at most at 28–56% of its historical abundance and should be considered depleted.

Distribution of North Pacific right whales ( Eubalaena japonica) as shown by 19 th and 20 th century whaling catch and sighting records

North Pacific right whales (Eubalaena japonica) were extensively exploited in the 19 th century, and their recovery was further retarded (severely so in the eastern population) by illegal Soviet

World‐wide genetic differentiation of Eubalaena: questioning the number of right whale species

Diagnostic characters, as well as phylogenetic and phylogeographic analyses, support the possibility that three distinct maternal lineages exist in right whales, with North Pacific E. glacialis being more closely related to E. australis than to North Atlantic E.glacialis.
