The minute snails of the troglobitic genus Zospeum are known from the southeastern Alps through the Dinarides and from the Pyrenees to the Cantabrian Mountains. The majority of Zospeum has been described from the northernmost region of... more
The study investigated the growth patterns, sex ratios, mean condition factor and proximate composition of the body fluid of male and female blue crab, Callinectes amnicola from tropical marine habitat. This is with a view to providing... more
The Eurasian badgers (Meles spp.) are widespread in the Palaearctic Region, occurring from the British Islands in the west to the Japanese Islands in the east, including the Scandinavia, Southwest Asia and southern China. The morphometric... more
The variability of shell valves in unionids from the Belaya River basin (southern Ural region) was analyzed for the first time using methods of multivariate analysis (nonmetric multidimensional scaling, discriminant analysis).The stable... more
Sexes cannot be distinguished with certainty by human observers in many avian species. However, some apparently monomorphic species have small but measurable sexual dimorphisms in biometry, which can be used to determine sex. Here, we... more
The Iberian Chiffchaff Phylloscopus ibericus has recently been accepted as a full species, but is still very difficult to distinguish from the Common Chiffchaff P. collybita when molecular and acoustic evidence is lacking. Distinguishing... more
The foramen magnum is an important landmark in the posterior part of the cranial base, which is largely formed by the occipital bone. The dimensions of the foramen magnum are clinically important because of the vital structures passing... more
Two competing taxonomic hypotheses have been proposed for the bats Artibeus jamaicensis and A. planirostris; one species with two intergrading populations or two allopatric sibling species. Morphometric analyses on specimens from the... more
... 2003), and species-level diversity is still underestimated, with new taxa recently described (Yoshiyuki and Lim 2005) or awaiting description (Francis et al. 2000; Struebig et al. 2005; Suyanto and Struebig 2007). Rhinolophid ...
ABSTRACT The biodiversity of tube-nosed bats (Murininae) from Asia has been underestimated by over 50%. Since 2005, eight taxa have been documented as distinct from the 19 previously known species. We describe three new species of Murina... more
Landmarks are the hallmark of biological shape analysis as discrete anatomical points of correspondence. Various systems have been developed for their classification. In the most widely used system, developed by Bookstein in the 1990s,... more
PURPOSE: Skull morphometrics is very important in archaeology and forensic sciences for sex identification, especially when only limited osteometric data are available. The foramen magnum (FM) and occipital condyles, appears to be the... more
Analyses of the dimensions and morphology of spermatozoa can be useful in the identification of mammalian species. We compared and contrasted sperm morphology and dimensions in 9 genera and 18 species of the family Cricetidae. Spermatozoa... more
The aim of the present study is to evaluate authenticity of Cornu aspersum maximum snails derived from farms in Greece based on their morphological characters. Shell morphometric traits, weight, shell pattern and mantle color, were... more
Purpose The fossil record of postcranial remains assigned to Allodaposuchidae is currently sparse. However, the Late Cretaceous paleontological site of Lo Hueco (Cuenca, Spain), from where two new taxa of allodaposuchid have been... more
