Rapid development of foraging ability is critical for phocids. In northern elephant seals Mirounga angustirostris, juvenile survivorship is low compared with adults and foraging difficulties are potentially associated with increased mortality. At Ano

Quantifying the dispersion and habitats of far-ranging seabirds, turtles, and cetaceans is essential to assess whether zoning strategies can help protect uppertrophic marine predators. In this paper, we focus on Black-footed Albatross (Phoebastria ni

The California Current System (CCS), a highly variable eastern boundary system, sup- ports a rich marine mammal fauna. Variation in local coastal upwelling, coupled with larger scale processes (El Nino/La Nina) affects the productivity and distributi

A variety of sources was considered, illustrating the predominantly uniform exposure at a distance and highly nonuniform exposures close to sources. The measurement of both electric and magnetic fields was considered for near field situations hut whe

Background: Occupational exposure to extremely low frequency (ELF) magnetic fields (MF) in the UK general population is poorly documented. Aims: To assess levels of occupational exposure to ELF MF in the UK and evaluate the use of a rigid job-exposur

ELectric and magnetic fields from radiofrequency sources are generated both deliberately and adventitiously. This review examines the nature of those fields and the practical aspects of field strength measurements including associated potential hazar

Hardy water lilies (Nymphaea cultivar ‘Marliacea carnea’) were grown out-of-doors at Phoenix, Arizona in sunken metal stock tanks located within open-top, clear plastic-wall, CO2-enrichment chambers; two were maintained at a CO2 concentration of

There is an unexplained association between exposure to the magnetic fields arising from the supply and use of electricity, and increase in risk of childhood leukaemia. The UK Childhood Cancer Study (UKCCS) provides a large and unique source of infor

An expanding body of research indicates that exposure to contaminants may impact marine mammal health, thus possibly contributing to population declines. The harbor seal population of the San Francisco Bay (SFB), California, has suffered habitat loss
