An Examination of Gene Flow Among Distinct Management Units of The Reddish Egret
The Reddish Egret (Egretta rufescens) is one of the least studied herons in North America. It ranges from Baja California to the Bahamas, north to Texas and Louisiana and southwards to Central America and the northern part of South America. I examined gene flow and genetic diversity among …

Molecular Genetic Assessment of Population Structure, Paternity, and Sex Ratios for the Reddish Egret
We examined distantly isolated colonies of Reddish Egret to determine global population genetic structure. We analyzed 13 polymorphic satellites and used nine of them to accomplish seven goals: 1) to assess range wide population differentiation among Reddish Egret (Egretta rufescens) populations, …

Wintering Reddish Egret (Egretta Rufescens) Foraging Response To Environmental Variability On The Southern Texas Gulf Coast
The Reddish Egret (Egretta rufescens) is a rare species of heron due to its limited geographic range as well as its narrow habitat requirement, relying exclusively on coastal tidal flats throughout its yearly cycle. It is therefore vulnerable to stressors ranging from human coastal development to …

Investigation of Natural Zeolitic Tuffs on their Ability for Sewage Cleaning Purposes
… waters. The material used was brownish and reddish zeolitic tuffs. Both materials were found to be very different from each other in their chemical and mineralogical compositions. The untreated sample of reddish zeolitic tuff showed a very high capacity for ammonium adsorption (46g/kg) from …

Mechanisms of Pteridine-Ommochrome Interactions in Drosophila Melanogaster
… (red pigments), contribute to the typical reddish-brown eye color of wild-type Drosophila melanogaster. Each pigment is the end product of a seemingly unrelated metabolic pathway (Ziegler 1961; Kaufman 1967a). Mutations which alter the synthesis of these pigments are manifested as numerous …

Volatile Compounds in Vine Tea (Ampelopsis grossedentata)
… tea infusions had acidic pH values and dark, reddish-yellow color. Type of water and vine tea sample both affected the overall volatile chemical composition of vine tea infusions. A total of fifty-six volatile components were identified in vine tea infusions. However, only seven aldehydes …

Phakopsora pachyrhizi growth in tissue of leaves from resistant and susceptible soybean germplasm
… rust is characterized by the development of reddish-brown (RB) lesions or a symptomless immune response, though considerable variation in lesion diameter, color and sporulation has been observed among resistant soybean germplasm accessions that develop RB lesions. The objective of this study …

Investigations of the geomorphologic and pedologic system of sedimentary vega deposits from Lanzarote (Canary Islands) supported by luminescence dating – important steps towards their palaeoclimatic interpretation
… in a palaeoclimatic way. The alternation of reddish-clayey and yellowish-silty layers tracks changes of soil humidity on Lanzarote rather than variations of the composition of Saharan dust. Due to the colluvial dynamics of the valleys, reddish-silty layers in the valley bottoms are no …

Mechanisms Causing Ferric Staining in the Secondary Water System of Brigham City, Utah
… reservoir has, during some years, exhibited reddish-brown staining when used by Brigham City for irrigation. I propose that seasonal fluctuations in the reservoir chemistry create an environment conducive to dissolving iron from the iron-rich sediments, which subsequently precipitate during …

Effect of glycerol and water activity on the processing and properties of egg white-based bioplastics
… bioplastics are investigated. Lighter, more reddish and less yellowish sheets with a decreased thickness and transition temperature, improved mechanical properties and constant moisture content can be obtained by increasing Aw. Increasing the GLY content results in the same type of changes …

Carbonate Carbon Isotope Chemostratigraphy from the Ruby Ranch Member of the Cedar Mountain Formation in the Western San Rafael Swell
… Ranch Member in this area consists mainly of reddish grey and greenish gray silty-sandy mudstones with abundant carbonate nodules suggestive of paleosol development. For this study samples were collected approximately every 25 cm and were used to construct a C-isotope curve using carbonate …
