Sperm was collected by making 2-3-cm cuts into the soft part of the prosomal
ventral cuticle from the base of the appendages toward the lateral margin.
Mucor fragilis on Latrodectus geometricus' prosomal
cuticle around cervical grooves and eyes; subject imaged 3 days after inoculation.
The calanoids, hereafter referred to as copepods, were further divided by size: 1) small copepods (<2 mm prosomal
length [PL]); and 2) large copepods (>2 mm PL).
Harvestmen (Opiliones) have a distinctive pair of prosomal
exocrine glands opening to the surface via ozopores usually placed in the vicinity of the second leg pair.
2005) reported mean prosomal
width (PW) for adult females in Pleasant Bay, Massachusetts was 230 ram.
The large prosomal
nerve mass that supplies innervation to the musculature of the legs and fangs is located in the anterio-ventral region of the cephalothorax (Foelix 1996; Punzo & Punzo 2002) and damage to this nerve mass coupled with the loss of hemolymph may have accounted for the collapse of the spider.
The smallest 14 animals (prosomal
width: 16-18 cm) were assigned to the laboratory running wheel (LRW) group; the smallest animals were selected for this group because pre-constructed running wheels could only fit animals of prosomal
width less than 18.
2]) of the relationship between prosomal
width and weight for horseshoe crabs (Limulus polyphemus), loge(Wt)=[log.
complex of male with coxae of legs II and IV meeting in the midline, but coxae I and III not so (Fig.
The sex, prosomal
width (PW; to the nearest 1 mm), and weight (to the nearest 10 g) were recorded from a sample of individuals that were collected from the vicinity of each breeding beach.
exocrine scent glands, also called defensive or repugnatorial glands, are an important synapomorphic character of Opiliones (Martens 1978).
Limb lengths of both populations were standardized to a mean prosomal
wet mass of 0.
