Aspects of biology of Gabon prawn, Atya gabonensis (Giebel, 1875) was investigated in the confluence of River Niger and Benue, North-Central Nigeria. A total of 2,175 specimens were collected from January to December, 2017 by fishermen using combination of gears (drag nets, set traps and traditional gear known as “Ahina”) and transported in icebox containing water to the laboratory for further ...

The embryonic period is characterized by organogenesis and accompanying dynamic changes in external features. The measurement of human embryos has been limited to whole body dimensions, such as crown-rump length. More detailed measurements would add quantitative information about these characteristic events and provide a better understanding of normal and abnormal embryonic development. In the ...

PURPOSE To describe a method for making morphometric analysis of the pores in the lamina cribrosa with a confocal scanning laser ophthalmoscope (SLO). METHODS Sixteen consecutive images were acquired with an SLO from the retinal surface to the bottom of the optic disc in +0.25-diopter increments. An He-Ne laser (633 nm) with a 20 degrees field of view was used. The images from each section we...

Long-term water temperature records are necessary for better understanding climate change impacts on freshwaters. We reconstruct summer water temperatures from three climatically sensitive mountain lakes in Austria using paleolimnological methods aiming to examine long-term thermal dynamics and lakes' responses to regional climate variability since the Little Ice Age. Our results indicate diver...

BACKGROUND Agenesis of the corpus callosum (ACC) is a developmental brain malformation associated with a wide spectrum of structural brain abnormalities and genetic loci. To characterize the diverse callosal morphologies and malformations of brain development associated with ACC, we report on the neuroimaging findings of 201 individuals diagnosed with corpus callosal abnormalities. METHODS We...

S U M M A R Y A contourite drift from offshore Brazil is mapped in detail and investigated using state-of-theart 3-D seismic data. The aim was to review the relevance of erosional features in contourite drifts accumulated on continental slopes. Topographically confined by growing salt diapirs, the mapped contourite ridge is limited by two erosional features, a contourite moat and a turbidite ch...

A study was conducted in two selected sites (Anuradhapura and Puttlam districts) to phenotypic ally characterize various types of village chicken present in Sri Lanka. Qualitative traits such as characteristics of plumage, comb, shank, eye and earlobe, and body condition score were recorded with a full inventory of management conditions. Quantitative traits included body weight and linear morph...

We present a quadriwave lateral shearing interferometer used as a wavefront sensor and mounted on a commercial non-modified transmission white-light microscope as a quantitative phase imaging technique. The setup is designed to simultaneously make measurements with both quantitative transmission phase and fluorescence modes: phase enables enhanced contrasted visualization of the cell structure ...

in this study, by examining the character of the morphometric and meristic in which cyprinion macrostomus samples obtained from different locality in tigris, morphometric character which are transformed subject to discriminant analysis and depending on grouping model to number of discriminant functions and according to importance of these totally variance, morphogical variance among populations...
