MODELING SELECTION AND EXTINCTION MECHANISMS OF BIOLOGICAL SYSTEMS

International Journal of Modern Physics C, 2011
In this paper, the behavior of a genetic algorithm is modeled to enhance its applicability as a modeling tool of biological systems. A new description model for selection mechanism is introduced which operates on a portion of individuals of population.

Inferring Extinction of Mammals from Sighting Records, Threats, and Biological Traits

Conservation Biology, 2011
Abstract:  For species with five or more sightings, quantitative techniques exist to test whether a species is extinct on the basis of distribution of sightings. However, 70% of purportedly extinct mammals are known from fewer than five sightings, and such models do not include some important indicators of the ...

Biological Rhythmicity in Subterranean Animals: A Function Risking Extinction?

2014
In this chapter, we discuss evidence of regression of circadian locomotor activity in exclusively subterranean species (troglobites), having fishes as models, by comparing such findings with observations on related epigean (surface) species, that may also form self-sustained subterranean (troglophilic) populations. These results favor the hypothesis of

Σkynet: A Novel Biologically Inspired Near Extinction Reconstruction Model

2016
The present work aims to develop a fundamentally novel computational model for reconstructing complex software systems, following some massive internal failure or external infrastructure damage. The present model mimics the biological process of information transmission in terms of transcription and subsequent translation, introducing novel terms such ...
