Let G and H be graphs. The Ramsey number R(G, H) is the least integer such that for every graph F of order R(G, H), either F contains G or F contains H . Let Bn and Wn denote the book graph K2 +Kn and the wheel graph K1 + Cn−1, respectively. In 1978, Faudree, Rousseau and Sheehan computed R(C4, Bn) for n ≤ 8. In this paper, we compute R(C4, Bn) for 8 ≤ n ≤ 12 and R(C4, Wn) for 4 ≤ n ≤ 13. In pa...

Most biogeographers will probably agree with Ebach et al. (2003) that an essential goal of biogeography is to ‘discover why organisms are distributed the way they are today’ (citing Platnick & Nelson, 1978). Moreover, many also agree that this is achieved by uncovering ‘the patterns of spatial distribution attained by life on earth and the means by which these distributions were achieved’ (citi...
