[J] J. Appl. Math. Comput. 17, No. 1-2, 195-215 (2005). ISSN 1598-5865; ISSN 1865-2085/e

The system $$y_i'= y_i(a_i- c_i y_i- b_i y_3),\quad i= 1,2,$$ $$y_3'= y_3(- a_3+ b_3 y_1+ b_4 y_2),$$ with positive, variable coefficients is investigated with respect to permanence, extinction and global stability. For periodic coefficients also periodic solutions are studied.
