Computation of population and physiological risk parameters from cancer data
A biological hypothesis known as the "two-stage cancer model" conceptualizes carcinogenesis in mathematical terms. Prof. W. Thilly (MIT) and Prof. S. Morgenthaler (ETH,) and their students, especially Dr. Pablo Herrero-Jimenez have organized age- and birth cohort-specific cancer mortality data from …

The biology, distribution and ecology of Lampanyctodes hectoris and Maurolicus muelleri along the South-African coast
… fishing pressure brings about a change in these parameters. Samples of L. hectoris taken from commercial catches and research cruises, and samples of M. muelleri obtained from research cruises were analysed to obtain the biological parameters. L. hectoris spawning in the southern Benguela Current …

Lepeophtheirus salmonis, parasitizing three species of pacific salmon (Oncorhynchus spp.): host variations in load, morphology, fecundity, and genetics of the salmon louse
<p>"The purpose of this study is to determine biological parameters of salmon lice (Lepeophtheirus salmonis) as they parasitize different species of Pacific Ocean salmonids off the north Pacific coast of Washington State. Parasite load counts of L. salmonis were made and individuals were collected …
