Anuran males and females adopt different reproductive and behavioral strategies in different contexts.We investigated the reproductive ecology and territorial behavior of the treefrog Boana goiana (B.Lutz, 1968) from the Brazilian Cerrado.We hypothesized that competitor density/proximity would increase the behavioral responses of B.goiana males, an
Research on nanomaterial exposure-related health risks is still quite limited; this includes standardizing methods for measuring metals in living organisms.Thus, this study validated an atomic absorption spectrophotometry method to determine fertility and bioaccumulated iron content in Drosophila melanogaster flies after feeding them magnetite nano
Introduction.The problem of contact fatigue Lacrosse - Cages damage of rails has become especially urgent with the intensified railway freight load.An effective method of studying various damage factors is mathematical simulation of the dynamics of motion and accumulation of contact fatigue damage in the rail material.The damage accumulation simula
