Continuous versus discrete single species population models

SINGLE SPECIES POPULATION MODELS 683 3 of this paper we analyze a simplified version of the structured floater- resident-disperser model introduced by Hanski (1989). Our approach con- tains the pure contest-type, the pure scramble-type and the Ricker model as special cases of a wide range of discrete models. ...read more

Sustainability in single–species population models

Single-species population models forces the modeller to describe the population life-history as a sequence of equal duration age classes, thus effectively precluding the identification of such age classes with functional categories, instars, developmental stages or whatever (Leslie 1945, 1948). ...read more

 

Population Ecology in Practice | Wiley

The doubling time (t d) of a population is the time required for the population to grow to twice its size. We can calculate the doubling time of a geometric population using the equation: N t = λ t N 0 by exploiting our knowledge of the fact that the population (N) is twice its size (2N) after the doubling time. N t d = λ t d × N 0. 2N 0 = λ t d × N 0. λ t d = 2N 0 / N 0. λ t d = 2 ...read more

1/29/2009 · Abstract Population features inferred from single‐species, age‐structured models are compared to those inferred from a multispecies, age‐structured model that includes predator‐prey interactions among three commercially harvested fish species—walleye pollock, Atka mackerel, and Pacific cod—on the Aleutian Shelf, Alaska. The multispecies framework treats the single‐species models ...read more

 

CONTINUOUS VERSUS DISCRETE SINGLE SPECIES POPULATION

4/25/2019 · Integrated population models (IPMs) have become increasingly popular for the modelling of populations, as investigators seek to combine survey and demographic data to understand processes governing population dynamics. These models are particularly useful for identifying and exploring knowledge gaps within life histories, because they allow investigators to estimate biologically … ...read more

5/25/2007 · One of the most basic and milestone models of population growth was the logistic model of population growth formulated by Pierre François Verhulst in 1838. The logistic model takes the shape of a sigmoid curve and describes the growth of a population as exponential, followed by a decrease in growth, and bound by a carrying capacity due to environmental pressures. ...read more
