genus acomys comprising 14 species from mouse like rodents and substituted in murinae subfamily. the aim of this research was surveying external, cranial and dental character differences among diverse populations of acomys dimidiatus in minab, boushehr and geno biosphere reserve. sampling was performed during summer 2003 and 2005. total of 52 species were collected from mentioned sites. the res...

forty-nine preserved specimens (31 male and 18 female) of trachylepis aurata transcaucsasica were examined with respect to metric and meristic features and dry skull anatomy to assess sexual dimorphism. thirty-one morphological characters and 36 anatomical characters in dry skulls were examined. subdigital lamellae under the forth toe, neck length, neck length/snout vent length, and six skull c...

Cranial and post-cranial variation is described for a large series of specimens spectacled porpoise from Argentina compared with that other areas the Southern Hemisphere. Condylobasal length in 54 adult skulls was 276-424. Tooth counts were 16-26 17-23 upper lower jaws, respectively. Total number vertebrae (n = 20) 66-70. The rostrum may be relatively smaller Auckland Islands than regions.

DIAGNOSIS. Leptonycteris yerbabuenae (Fig. 1) is 1 of 4 North American bats with a nose leaf. L. yerbabuenae can be distinguished from Choeronycteris mexicana and Macrotus californicus by the absence of a conspicuous tail and presence of brownish pelage in L. yerbabuenae (Arita 1999). Pelage of L. yerbabuenae is shorter and denser in comparison to the longer and fluffier pelage of L. nivalis (D...

Species of the genus Plecotus, which have distinctive morphology with their long ears, are common in Palearctic region. Its distribution area Türkiye is seen as fragmented. In present study, a new record for Plecotus auritus (Linnaeus, 1758) from Bolu province given. External characteristics, fur coloration, skull morphology, morphometric measurements, and some ecological characteristics specim...

The differences in rorqual feeding ecology have been linked to the presence of different morphological markers. Antarctic minke whale (Balaenoptera bonaerensis Burmeister, 1867) and common acutorostrata Lacépède, 1804) are closely related species, but their not fully investigated. In this study, we compared 21 skull 11 apparatus (baleen mouth-related parts) measurement points between these two ...

Intraspecific variation in size along spatial and environmental gradients has been documented many studies, different hypotheses have proposed to explain these patterns of geographic variation. We explored 4 island 35 mainland samples the Edible Dormouse ( Glis glis Linnaeus, 1758) from western Balkans Slovenia, Croatia, Bosnia Herzegovina, Montenegro, Serbia. Samples comprised 207 (mean ± SD=1...

This study was conducted to make the three-dimensional modelling of skull in Van cats by using computed tomographic images and determine morphometric features between sexes. The skulls 16 adult were used study. anesthetized animals scanned a Computed Tomography (CT) device their obtained. These converted structure MIMICS 20.1 software measurements calculated. It determined that total length (TL...

Sentinel species are important tools for studies of biodiversity and environmental health. The American mink (Neovison vison) has long been considered a sentinel of environmental contamination, since the species is known to be sensitive to a number of common contaminants, including polychlorinated biphenyls (PCB) and mercury. Mink may not always satisfy an important criterion of sentinels howev...
