Many genes influencing mammalian coat colours are well conserved. While genes responsible for pelage phenotypes in one species provide strong evidence for a candidate gene in a different species, the X-linked orange phenotype of the domestic cat is unique within mammals. The orange locus (O) undergoes X-inactivation, producing females that express both wildtype black (wt) and orange (variant) p...

This study aimed to first investigate the relationship between male ventral colour, body size and ectoparasite load, and then test, using an enclosure experiment, how body size and ventral colour influence male reproductive success in a non-territorial lizard. Individuals of the sexually dimorphic Australian skink, Pseudemoia entrecasteauxii, were sampled in the field and male body size and ven...

The chemical composition of sweet potato (Ipomoea batatas var. Portu Orange), grown in Ukraine, was studied to determine its potential shortbread technology. Orange has a high content starch (11.2 %), natural sugars (4.7 dietary fiber (3.8 %) and food pigments. To obtain the highest quality characteristics preserve antioxidant properties during drying, an innovative microwave vacuum drying meth...

Behavioral interactions between coexisting species may reflect underlying ecological interactions or may arise from factors unrelated to ecological interactions between species. We examined behavioral interactions between two coexisting, migratory wood warblers that competitively interact on breeding territories in central Arizona, USA. The larger Orange-crowned Warbler (Vermivora celata) is ag...

Green tea leaves have high contents of phenolic compounds which has strong antioxidant properties but can have bitter taste which makes it less useful in food applications. Encapsulation in nanoliposomes could mask undesirable taste of green teas components and protect them against processing and storage. The objective of this study was to: 1) produce and evaluate physical properties of green t...

Hypoxia is a potential threat to various horticultural cropsin lands prone to flooding. Citrus is mostly known as a sub-tropical crop that is often exposed to environmental stresses. In order to evaluate response of six different citrus genotypes, including sour orange, rough lemon, Trifoliate orange, Troyer citrange and two local genotypes labeled; CRC1 and CRC2 to flooding conditions, an expe...

Birds have impressive physiological adaptations for colour vision, including tetrachromacy and coloured oil droplets, yet it is not clear exactly how well birds can discriminate the reflecting object colours that they encounter in nature. With behavioural experiments, we determined colour discrimination thresholds of chickens in bright and dim light. We performed the experiments with two colour...

background the increase in intestinal permeability following damage to the intestinal mucosa in any surgical procedure, trauma or fasting is well- known. objectives our objective was to experimentally evaluate whether antioxidant consumption is associated with decreased intestinal damage in intestinal surgical procedures. materials and methods forty rabbits were used to compare the pathological...
