Existence of global attractor for the Trojan Y Chromosome modelX. P. Zhao, B. Liu and N. Duan, Electronic Journal of Qualitative Theory of Differential Equations, 2011.![]() This paper is concerned with the long time behavior of solution for the equation derived by the Trojan Y Chromosome (TYC) model with spatial spread. Based on the regularity estimates for the semigroups and the classical existence theorem of global attractors, we prove that this ...

Analysis of the Trojan Y chromosome model for eradication of invasive species in a dendritic riverine systemJ. B. Gutierrez, M. K. Hurdal, R. D. Parshad and J. L. Teem, Journal of Mathematical Biology, 64:319-340. 2011.![]() The use of Trojan Y chromosomes has been proposed as a genetic strategy for the eradication of invasive species. The strategy is particularly relevant to invasive fish species that have XY sex determination system and are amenable to sex-reversal. In this paper we study the ...

Can transposable elements be used to drive disease refractoriness genes into vector populations?M. G. Kidwell and J. M. C. Ribeiro, Parasitology Today, 8:325-329. 1992.![]() A number of biological procedures are currently being considered as alternatives to insecticide-based methods for the control of insect vectors of disease. Among these are the adaptation of various genetic mechanisms to drive genes of interest, such as refractoriness to malaria ...
