Drivers of population dynamics and juvenile mortality in Northwest Atlantic harp seals. [PDF]
Ecol ApplAbstract Human‐induced threats to terrestrial and marine wildlife are on the rise, and while some species face a single major threat, others face multiple concurrent threats. Harp seals, an abundant pinniped in the North Atlantic that was historically depleted by human harvest, are one such species. Although commercial and subsistence harvests remain a

Geophysical Monograph Series, Page 1-26., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Pseudopregnancy in harp seals (Phoca groenlandica) [PDF]
Reproduction, 1994 Concentrations of circulating progesterone were monitored in a captive breeding group of harp seals. Five females were monitored for 2 years, over which time they either became pregnant (four instances) or displayed an overt pseudopregnancy (five instances). Only one female exhibited consecutive pseudopregnancies.

Report of the NAMMCO-ICES Workshop on Seal Modelling (WKSEALS 2020)
NAMMCO Scientific Publications, 2021 To support sustainable management of apex predator populations, it is important to estimate population size and understand the drivers of population trends to anticipate the consequences of human decisions. Robust population models are needed, which must

In search of virus carriers of the 1988 and 2002 phocine distemper virus outbreaks in European harbour seals [PDF]
, 1995 European harbour seal (Phoca vitulina) populations decreased substantially during the phocine distemper virus (PDV) outbreaks of 1988 and 2002. Different hypotheses have stated that various seals and terrestrial carnivore species might be the source of ...
