The characteristics of species within a community can influence the number of species that can coexist within that community. In particular, body size can constrain how many individuals can 'fit' into a community, and overlap in resource use between species depends on differences in their body sizes. Here, using data from 18 communities of strongyloid nematodes living in the stomachs of macropo...

Parabronema skrjabini is a spirurid nematode of the family Habronematidae that lives in the abomasum of ruminants such as sheep and goats. The purpose of this study was to investigate the molecular and morphological aspects of Parabronema skrjabini in sheep and goats in Iran. The worms were collected from these animal species from three different regions. An internal transcribed spacer 2 riboso...

Females of Mermis nigrescens, a nematode parasitic on grasshoppers, climb through terrestrial vegetation where they lay their eggs. The 100-mm-long body of these nematodes bridges gaps in this three-dimensional substratum, and crawls efficiently over planar surfaces. The nematodes do not use the classical undulant pattern of nematode locomotion as one coordinated unit; instead they propel thems...

introduction: the human anthropometric characteristics are surveyed in anthropology. anthropology is used in archeology, rehabilitation and legal medicine. the purpose of this study was to determine femur which has a special place in the science of anthropometry. methods: to measure the femur, both direct and indirect methods was used. the direct method of measuring the 113 femur in dissection ...

New informat ion is reported on the parasit ism of Heterotylenchus autumnalis upon its principal known host, Musca autumnalis. Black to b rown spots are produced on the cuticle of all infected host larvae where the nematode penetrated. The principal damage to the host is castration of the female. In laboratory tests nematode larvae were not infective and did not leave the hosts before the femal...

Introduction: Correct interpretation of kidney images requires the knowledge of its normal size. This study aimed to establish normal values for kidney length and parenchymal thickness and identify the potential related factors in a group of Iranian adults. Methods: Renal dimensions, including length and parenchymal thickness were measured by sonography in 103 individuals with n...
