the distribution of yellowfin seabream populations in estuaries and inland rivers in coastal area of the persian gulf and strait of hormuz is presented. based on morphological and mersitic characteristics and also color pattern, these populations are assigned to the recently described sparid fish, acanthopagrus arabicus iwatsuki, 2013 which is distinguished by pelvic and anal fins vivid or stro...

Neurosecretory cells in Lymnaea are the follower cells of a network of interneurones consisting of four different cell types, three of which are inhibitory and one excitatory. One identified interneurone, the visceral white interneurone (VWI), inhibits the Yellow Cells and Yellow-green Cells, or converts Yellow Cells from single spiking to doubletting or bursting. A second interneurone, RPeDl, ...

WHILE THE TWENTIETH CENTURY HAS PRODUCED GREAT DEVELOPMENTS IN THE EPIDEMIOLOGY OF YELLOW FEVER AND IN TECHNIQUES FOR ITS CONTROL IN URBAN AREAS, THE ESSENTIAL METHOD OF CONTROL HAS NOT CHANGED: it is still the elimination of the urban vector, Aëdes aegypti. The aim of those responsible for yellow fever control in Africa should be the eradication of this vector from all urban communities in the...

Genomic components of the begomovirus causing yellow mosaic disease (YMD) in soybean in Delhi were cloned, sequenced and infectivity proved. Nucleotide sequence analysis of the virus isolate revealed more than 89% identity with Mungbean yellow mosaic India virus (MYMIV) and therefore it is designated as soybean isolate of MYMIV (MYMIV-[Sb]). Total nucleotide and predicted amino acid sequence an...

Pattern of black and yellow The tortoise shell pattern consists of yellow hairs sprinkled lightly among black hairs in a few irregular, asymmetrical regions over the body. This is the typical pattern of family D, a highly inbred strain which never shows white. Occasionally a foot has a small area of segregated yellow at the tip. Large areas often appear to be solid black. The tricolor pattern o...

The regulation of gene expression controls development, and changes in this regulation often contribute to phenotypic evolution. Drosophila pigmentation is a model system for studying evolutionary changes in gene regulation, with differences in expression of pigmentation genes such as yellow that correlate with divergent pigment patterns among species shown to be caused by changes in cis- and t...

range, yellow perch, Perca flavescens, are viewed variously as a sport fish, a valuable food fish, an important forage species, or a nuisance trash fish with little commercial or sport value. Attitudes toward yellow perch vary with its relative availability and with historical regional preferences. In much of the midwestern and central Atlantic areas of the United States and in central Canada, ...

Deficiencies in the amount of chlorophyll in the cotton plant have been reported in relatively few instances. BALLS (1908) made a cross between an upland cotton with light green leaves and a dark green Egyptian cotton. He states that in the Fz generation, plants with light green leaves and plants with dark green leaves appeared in a 3 : 1 ratio. STROMAN and MAHONEY (1925) recovered two chloroph...

Yellow nail syndrome is a type of lymphatic dysplasia syndrome characterised by the triad of yellow nails, lymphoedema, and pleural effusions. The case history is presented of a 70 year old patient with yellow nail syndrome who complained of dyspnoea caused by massive chylothorax. The patient underwent insertion of a pleuroperitoneal shunt which resulted in abdominal distension and deterioratio...

1. Ornamental carotenoid coloration is commonly based on several different pigments with different nutritional and metabolic constraints. The identification and quantification of carotenoid pigments is therefore crucial to the understanding of signal content and signal evolution. 2. In male widowbirds ( Euplectes spp.), the striking yellow and red carotenoid colours have been measured by reflec...
