Renal lesions in Baltic grey seals (Halichoerus grypus) and ringed seals (Phoca hispida botnica)

Article Abstract:

Research suggests that renal lesions in Baltic Sea ringed and grey seals are due in part to organochlorine contamination. Kidney changes consist primarily of focal replacement of normal epithelial cells by proliferations of multilayered cells. Seals in zoos which were fed fish from the Baltic Sea also exhibited these physiological changes.

Development in the Baltic grey seal (Halichoerus grypus) and ringed seal (Phoca hispida) populations during the 20th century

Article Abstract:

Research of seal hunting patterns in the Baltic Sea from the beginning of the 20th century shows excessive hunting lowered grey and Baltic ringed seal populations. Since 1965, lowered fertility rates have been the strongest factor in small populations.

Bone mineral density in male Baltic Grey Seal (Halichoerus grypus)

Article Abstract:

Noninvasive computed tomography (pQCT) is used to study bone mineral density in male Baltic grey seals between the age of 4-23 years of age. The results indicate different responses over time in trabecular and cortical bone.
