Jumping Performance and Behavior of the Globular Springtail <i>Dicyrtomina minuta</i>.. Springtails are among the most abundant arthropods on earth and they exhibit unique latch-mediated spring-actuated jumping behaviors and anatomical systems. Despite this, springtail jumps have not been well described, especially for those with a globular body plan. Here, we provide a complete description and visualization of jumping in the globular springtail Dicyrtomina minuta . A furca-powered jump results in an average take-off velocity of 1 ms -1 in 1.7 ms, with a fastest acceleration to liftoff of 1938 ms -2 . All jumps involve rapid backwards body rotation throughout, rotating on average at 282.2 H…

Xenopsylla buxtoni fleas as a dominant species harboring multiple infections of Wolbachia lineages in the ancient plague epicenters of Iran.. Fleas are permissive and euryxenous ectoparasites capable of transmitting numerous ancient and new pathogens among warm-blooded animals, including humans. Precise identification of flea species involved in disease transmission and understanding the highly specialized morphological characteristics associated with their ectoparasitic lifestyle is essential. Likewise, identifying endosymbionts such as Wolbachia-which have long-lasting and intimate relationships with their hosts-will enhance our knowledge of the epidemiology of flea-borne diseases and the…

The brown rat (Rattus norvegicus), also known as the common rat, street rat, sewer rat, wharf rat, Hanover rat, Norway rat and Norwegian rat, is a widespread, common species of rat. One of the largest muroids, it is a brown or grey rodent with a body length of up to 28 cm (11 in) long, and a tail slightly shorter than that. It weighs between 140 and 500 g (4.9 and 17.6 oz). Thought to have originated in northern China and neighbouring areas, it has now spread to all continents except Antarctica, and is the dominant rat in Europe and much of North America, having become naturalised across the world. With rare exceptions, the brown rat lives wherever humans live, particularly in urban areas.…
