Heterodorus youbertghostai n. sp. is described and illustrated based on morphological, morphometric, and molecular data. The new species was found in two geographically distant points in northwestern Iran and is characterized by having angular lip region, separated from the rest body by a constriction, body length of 1,432.5 to 1,751.3 µm, odontostyle length of 24 to 28 µm, rod-like odontophore...

Morphometric light microscope measurements were made on 154 abdominal aortas from 77 Guatemalan Indian-white (ladinos) men and from 77 new Orleans white men, aged 15 to 54 years. In each case, means were derived from 12 points measured independently. A progressive increase in intimal lipid with increasing age was observed in men from both countries. Extracellular intimal lipid was consistently ...

The aim of this study was to characterize the pattern of shell occupation by the hermit crab Isocheles sawayai Forest and Saint-Laurent, 1968, from the Caraguatatuba region. The percentage of shell types that were occupied and the morphometric relationships between hermit crabs and occupied shells were analyzed from systematized collections that were conducted monthly from July 2001 to June 200...

In recent years, remote sensing, morphometric analysis, and other computational concepts and tools have invigorated the field of geomorphological mapping. Automated interpretation of digital terrain data based on impartial rules holds substantial promise for large dataset processing and objective landscape classification. However, the geomorphological realm presents tremendous complexity and ch...

The aim of this study was to analyse the prevalence and morphometric parameters of idiopathic osteosclerosis (IO) in a Chilean population. IO is an intraosseous growth of compact, benign, unilocular, non-expandable bone that is referred to as an anatomical variation. A cross-sectional study was performed using 1000 digital panoramic radiographs of adults in which data on the location (maxillary...

studies on the biometric parameters of a species to have an important role in its population or stock management and conservation. present study investigated the morphometric, meristic, length-weight relation (lwrs), length-length relation (llrs) and growth status (k and kn) of the redline torpedo barb, p. denisonii collected during august 2012 to july 2013 from river valapattanam, kerala. the ...

owing to reduction of sturgeon stocks in various water bodies, artificial propagation has become significantly important for stock restoration and appropriate broodstock selection is vital in this process. selection of suitable broodstocks may influence the quality and quantity of obtained eggs and larva. the present study aimed to examine correlation between some morphometric and reproductive ...

the carob moth, ectomyelois ceratoniae (zeller), belongs to the family pyralidae and the subfamily phycitinae. in spite of some features of sexual dimorphism in size and shape in the order lepidoptera and the mentioned family, it has not been recorded in this species. in the current study, sexual dimorphism in the wing shape and size of carob moth on four hosts (pomegranate, fig, pistachio and ...

in central part of kopeh dagh there is an array of active right-lateral strike-slip faults that obliquely cut the range and produce offsets of several kilometers in the geomorphology and geological structure. geomorphic indices indicate the presence of differential uplifting in history of this area. tectonic activity of the study area is investigated by a large number of dem derived catchments ...

background: no data is available on morphology and genetic characteristics of echinococcus granulosus derived from donkeys of iran, despite of its existence in donkeys.in the present study morphometric variations of the rostellar hooks of protoscoleces and genotype characteristics of hydatid cyst of donkey from iran were determined. methods: protoscoleces prepared from hydatid cyst of donkey of...
