Sexual segregation in foraging behavior varies with breeding site and year in seabirds

Abstract In many animals, behavioral sex differences can produce spatial or temporal segregation, known as sexual segregation, which is thought to reduce competition and satisfy sex-specific physiological demands. In breeding central-place foraging seabirds, sexual segregation ma...

Mean square estimates for the error terms of sums of the greatest common divisor

Abstract We investigate the mean square behavior of error terms that arise in the summation of gcd ( n 1 , … , n k ) $\gcd (n_1,\ldots ,n_k)$ gcd left parenthesis n 1 comma ellipsis comma n Subscript k Baseline right parenthesis with n 1 … n k ≤ x $n_1\ldots n_k \le x$ n 1 ellips...
