Food consumption estimates of Barents Sea harp seals
The consumption of various prey species, required by the Barents Sea harp seal (Phoca groenlandica) stock in order to cover their energy demands, has been estimated by combining data on the energy density of prey species and on seasonal variations in the

Arctic seals as tracers of environmental and ecological change
Knowledge of species trophic position (TP) is an essential component of ecosystem management. Determining TP from stable nitrogen isotopes (δ15N) in predators requires understanding how these tracers vary across environments and how they relate to ...

Health, disease, mortality and survival in wild and rehabilitated harbor seals (Phoca vitulina) in San Francisco Bay and along the central California coast [PDF]
Conventional methods for health assessment of wild-caught and stranded seals were used to describe the disease status of harbor seals in California. Clinical chemistry, infectious disease prevalence, immune function, and contaminant data were collected ...

An acoustical investigation of the concert harp [PDF]
This thesis is a report of acoustical research on the concert harp. The harp has an established place in the symphony orchestra and is reacquiring its role as a solo chamber instrument that it had before the development of the modern piano. As far as

The paucity of observations of wild polar bears (Ursus maritimus) caching of food (including hoarding, i.e., burying and remaining with a kill for up to a few days) has led to the conclusion that such behavior does not occur or is negligible in this ...

In the 1820’s, a relatively large harbour seal population may have inhabited the Tana River Estuary. Due to heavy persecution, especially in the 1920’s and 1930’s, it was reduced dramatically, and today there are probably less than 40 individuals left ...

This study aimed to investigate the effects of cellulase and Lactobacillus plantarum on the silage quality, in situ digestibility, and microbial communities of apple pomace silage. The combined supplementation of cellulase and Lactobacillus plantarum in apple pomace silage improved fermentation quality and enhanced rumen utilization efficiency.

This study assesses whether a saline aquifer in the German North Sea can sustain industrial‐scale CO2 injection at 10 Mt/year over 30 years. A 3D reservoir model is used to compare static capacity with dynamically achievable storage. The work links site‐scale injection strategy design with basin‐scale pressure response, providing a framework for ...

This study reports the exceptional preservation of the Eocene freshwater bivalve Batissa sitakaraensis from Hokkaido, Japan. Multimodal analyses reveal that both the aragonitic shell mineralogy and the delicate organic periostracum retain their original structural and chemical characteristics after millions of years.
