The ovary of the roach Periplaneta americana has been studied by techniques of light and electron microscopy. Each ovariole (panoistic type) contains a linear array of oocytes in varying stages of development. Newly formed oocytes become encased by a layer of follicle cells and begin pinocytosis. All subsequent growth stages of the oocytes are dependent, in part, on this phenomenon. All of the ...

Introduction Perhaps, the most exciting equine discovery of the 20th century was that the Caspian is not a pony, but an ancient breed of miniature horse, previously believed to have been extinct for over a thousand years. These animals native of the areas around the Elborz Mountains and Caspian Sea in Iran, are extremely rare and were rescued from extinction in 1965 by an American L.FIROUSE [11...

Effect of temperature on activities of proteinases in intestinal chyme and mucosa was studied in three fish species (pike perch, zope, roach) belonging to different ecological groups by their nutrition type. There was revealed a significant difference of dependence of enzyme activities in chyme on temperature in the benthophage, roach (a higher level of relative activity in the range of lower t...

The predatory cladoceran Cercopagis pengoi has extended its range over the past decade from the Ponto-Caspian basin into the Baltic Sea and the Laurentian Great Lakes. This study employs mitochondrial DNA (mtDNA) sequence analysis to elucidate the invasion corridors exploited during this range expansion. The Caspian and Black Sea populations of C. pengoi exhibit marked genetic divergence, enabl...

Aim Impacts of invasive species may vary across invasion gradients, owing to trait-based sorting of individuals through dispersal: those aggregating at invasion fronts may be more aggressive and voracious. We examine, in the field and laboratory, variation in the predatory impacts of an invasive Ponto-Caspian crustacean Hemimysis anomala G.O. Sars, 1907 at two sites along a spatiotemporal gradi...

The article considers the original results of observations and analysis catches atherina (Atherina boyeri caspia (Eichwald)) by months stationary nets in Terek-Caspian fishery subarea (Republic Dagestan). size-weight age indicators spawning stocks have been characterized. For first time recent years conditions for western part Middle Northern Caspian are described. All biostatistical obtained (...

the authors state that " Religious groups have gone so far as to state that the VeriChip may be a realization of the Mark of the Beast as described in the New Testament. " The authors support this statement with an endnote referenc-ing a book of which I am the co-author. The statement is wrong on several counts. First, neither I nor my co-author, Liz McIntyre, head up or have formed any " relig...
