(1985), but its use in this paper is different and more theoretically appealing. Independent of development, the mortality process is defined by a

Each female contains at most only two mature eggs at a time, making it difficult to obtain an adequate and uniform cohort of first-stage juveniles (J1). Distri

The most important ingredients are nonlinearity, time lag and periodic forcing all of which seem realistic and, in fact, quite likely. The time-asymptotic final state of the predator-prey system was observed to depend not only on parameters but on initial con

Computer Communications and Networks systems. The advantages of the language are its ease of use, availability, convenience, and versatility. The use of SLAM would allow the scientists involved in the modeling effort to concentrate on biological processes rather than computer programming. An example is given in which the insect popula

Estimation of Stage—Specific Demographic Parameters for Zooplankton Populations: Methods Based on St and growth probabilities, which can be obtained from as few as three consecutive censuses. However, the estimates are ill-conditioned in the presence of sampling noise. Two regularization methods, truncated singular value decomposition and Tikhonov regularization (ridge regression) are examined as possible solutions.
