A common problem in morphometric studies is to determine whether, and in what ways, two or more previously established groups of organisms differ. Discrimination of predefined groups is a very different problem than trying to characterize the patterns of morphological variation among individuals, and so the kinds of morphometric tools used for these two kinds of questions differ. In this paper ...

The European Commission's Thematic Strategy for Soil Protection (COM(2012)46) identified soil erosion as an important threat to Union's (EU) resources. Gully is but hitherto poorly understood component of this threat. Here we present the results unprecedented attempt monitor occurrence gully across EU and UK. We integrate a module into 2018 LUCAS Topsoil Survey, which was conducted health statu...

When performing a regional-scale geomorphometric analysis, one might face a decision on whether to derive morphometric data from a low-resolution DEM or to calculate basic derivatives from a higher resolution dataset and average these data afterwards. This paper investigates differences between morphometric parameters (slope and aspect) derived from a resampled DEM and resampled morphometric da...

killifish (aphanius sophiae) of the cheshme-ali of damghan and shour river of eshteherd were studied and compared from morphological point of view. for morphometric studies, 34 truss morphometric measurements and  10 traditional  measurements  were made for each individual. nine meristic traits were counted. multi-variate analysis of variance (manova) revealed a significant different between va...

This work evaluates sperm head morphometric characteristics in adolescents from 12 to 18 years of age, and the effect of varicocele. Volunteers between 150 and 224 months of age (mean 191, n = 87), who had reached oigarche by 12 years old, were recruited in the area of Barranquilla, Colombia. Morphometric analysis of sperm heads was performed with principal component (PC) and discriminant analy...

Cape Colony, and towards the end of the year at Natal. It continued at various points in the beginning of 1862. Diphtheria was seen among the children of the civil population at Keisham Hoeck, in March 1862; and what is denominated ulcerated sore throat, with a tendency to catarrhal and bronchitic affections, was frequent at Cape Town, Port Elizabeth, and Fort Beaufort. Fever, mostly of the typ...

this study was designed to evaluate population variation and differentiation of bartail flathead, platycephalusindicus (linnaeus, 1785)in the iranian waters of the persian gulf using the morphometric and meristic characters. a total of 180 fish were collected by gill net from six stations (khormosa, bahrekan, shif, motaf, charak and bandar abbas) of iranian coasts of persian gulf including 30 f...
