Evolutionary change in one trait can elicit evolutionary changes in other traits due to genetic correlations. This constrains the independent evolution of traits and can lead to unpredicted ecological and evolutionary outcomes. Animals might frequently exhibit genetic associations among behavioural and morphological-physiological traits, because the physiological mechanisms behind animal person...

Efforts to understand nuclear organization in plant cells have received little assistance from the better-studied animal nuclei, because plant proteomes do not contain recognizable counterparts to the key animal proteins involved in nuclear organization, such as lamin nuclear intermediate filament proteins. Previous studies identified a plant-specific insoluble nuclear protein in carrot (Daucus...

Koblmuller et al. (2009) analysed molecular genetic data of the wolf in the Great Lakes (GL) region of the USA and concluded that the animal was a unique ecotype of grey wolf and that genetic data supported the population as a discrete wolf taxon. However, some of the literature that the researchers used to support their position actually did not, and additional confusion arises from indefinite...

The Animal Kingdom is an astonishingly diverse group. Together with plants and fungi one of the three major lineages multicellular eukaryotes. Due to anthropocentrism and/or genuine scientific interest, their origin diversification are pivotal modern evolutionary biology. In last few decades, dramatic technological advances in molecular biology computational power have generated new phylogeneti...

Animal testing is mandatory in drug and the gold standard for toxicity efficacy evaluations. This situation expected to change future as 3Rs principle, which stands replacement, reduction, refinement of use animals science, reinforced by many countries. On other hand, technologies alternatives animal have increased. The need develop depends on complexity research topic also extent currently use...

Semithin and thin sections of glutaraldehyde-fixed, epoxy resin-embedded animal tissues were treated with solutions of oxidized p-phenylenediamine (PPD). This method is suitable to reveal the general morphology of tissues in light microscopy, showing a high staining degree in some polyanion containing components. Posttreatments of thin sections with gold chloride solutions give considerable ele...

Controlled experiments using a calibrated crossbow to thrust stone-tipped spears into animal carcasses reveal a relationship between Levallois point morphology and their performance as spear points. A comparative study of morphometric variation of Levallois points from Levantine Mousterian contexts supports the hypothesis that the demand for stone spear points was an important factor in Levallo...
