Dispersal is a fundamental biological process that operates at different temporal and spatial scales with consequences for individual fitness, population dynamics, population genetics, and species distributions. Studying this process is particularly challenging when the focus is on microscopic organisms that disperse passively, whilst controlling neither the transience nor the settlement phase of their movement. In this work we propose a comprehensive approach for studying passive dispersal of microscopic invertebrates and demonstrate it using wind and phoretic vectors. The protocol includes the construction of versatile, modifiable dispersal tunnels as well as a theoretical framework quantifying the movement of species via wind or vectors, and a hierarchical Bayesian approach appropriate to the structure of the dispersal data. The tunnels were used to investigate the three stages of dispersal (viz., departure, transience, and settlement) of two species of minute, phytophagous eriophyid mites Aceria tosichella and Abacarus hystrix. The proposed devices are inexpensive and easy to construct from readily sourced materials. Possible modifications enable studies of a wide range of mite species and facilitate manipulation of dispersal factors, thus opening a new important area of ecological study for many heretofore understudied species.

一种全面且经济有效的方法,用于研究微小无脊椎动物的被动扩散,并以植物吞噬性螨类螨虫为例。

分散是一个基本的生物学过程,在不同的时空尺度上运作,对个体适应度,种群动态,种群遗传和物种分布产生影响。当研究的重点是被动分散的微观生物时,同时控制其运动的瞬态和沉降阶段时,研究此过程尤其具有挑战性。在这项工作中,我们提出了一种用于研究无脊椎动物显微无源扩散的综合方法,并使用风和谱向量对其进行了证明。该协议包括构建通用的,可修改的分散隧道,以及通过风或矢量量化物种运动的理论框架,以及适用于分散数据结构的分层贝叶斯方法。螨tosichellaAbacarus锥。所提出的装置是廉价的并且容易由容易获得的材料构造。可能的修饰使得能够研究广泛的螨虫种类并促进对分散因子的操纵,从而为迄今为止许多尚未被研究的种类开辟了新的重要的生态学研究领域。
