A new species of Allobates (Anura: Aromobatidae) from Parque Nacional da Amazônia, Pará State, Brazil.

We describe the fourth species of nurse-frog genus Allobates occurring in the southeastern Brazilian Amazonia. The new species is sympatric with Allobates femoralis, Allobates masniger and Allobates magnussoni, and inhabits the margins of streams in forested areas within Parque Nacional da Amazônia, on the western bank of the Tapajós River. Snout-to-vent length ranges between 14.9-16.1 mm among...

On a Two-Sided Turan Problem

Given positive integers n, k, t, with 2 ≤ k ≤ n, and t < 2, let m(n, k, t) be the minimum size of a family F of nonempty subsets of [n] such that every k-set in [n] contains at least t sets from F , and every (k − 1)-set in [n] contains at most t− 1 sets from F . Sloan et. al [11] determined m(n, 3, 2) and Füredi et. al [6] studied m(n, 4, t) for t = 2, 3. We consider m(n, 3, t) and m(n, 4, t) ...

Turan Related Problems for Hypergraphs

For an /-uniform hypergraph 3and an integer n, the Turan number ex(n, F) for F on n vertices is denned to be the maximum size \Q\ of a hypergraph Q C [n] not containing a copy of F C2\ as a subhypergraph. For 1 = 1 and f = Kk , the complete graph on k vertices, these numbers were determined by P. Turan. However, for I > 2, and nearly any hypergraph F, the Turan problem of determining the number...
