摘要: Speed is a key trait of animal movement, and while much already known about vertebrate speed how it scales with body mass, studies on invertebrates are sparse, especially across diverse taxonomic groups. Here, we used automated image-based tracking to characterize the exploratory (voluntary) 173 comprising 57 species 6 groups (Arachnida, Chilopoda, Diplopoda, Entognatha, Insecta, Malacostraca) 4 feeding types (carnivore, detritivore, herbivore, omnivore). Across all individuals, scaled mass following power-law relationship scaling exponent 0.19 (±0.04 standard error) an intercept 14.33 (±1.2). These parameters varied substantially group type. For first time, provide general empirically-derived allometric relationships broad invertebrates. As drives components interactions – such as encounter attack rates, or competition our study contributes deeper understanding role individual movement in population community level processes.
