Abstract

Cockroaches in a tropical forest stratify vertically both inter- and intraspecifically along micrometeorological gradients. At night, low wind speeds and unstable atmospheric conditions result in efficient vertical mixing of the air near the ground. Convective ascent of warm air imparts directionality to the pheromone- dispersion process. The occurrence of males at greater heights than pheromone- emitting conspecific females appears to be a mate-finding strategy.

摘要

热带森林中的蟑螂会在种间和种内沿着微气象梯度进行垂直分层。夜间，低风速和不稳定的大气条件导致近地面空气的有效垂直混合。暖空气的对流上升赋予了信息素扩散过程方向性。雄性出现在比释放同种信息素的雌性更高的位置，这似乎是一种寻找配偶的策略。
