Habitat heterogeneity that occurs within an individual's lifetime may favour the evolution of reversible plasticity. Colour reversibility has many different functions in animals, such as thermoregulation, crypsis through background matching and social interactions. However, the mechanisms underlying reversible colour changes are yet to be thoroughly investigated. This study aims to determine th...

urban green space is a fundamental and attractive element of cities around the world all through the year. selecting species resistant to dryness is an essential decision for planting them in the urban green space in arid and semi-arid regions. one of the most important experiments to introduce new plants in new regions is phenology of different species. in this study, the phonological characte...

Colour changes in animals may be triggered by a variety of social and environmental factors and may occur over a matter of seconds or months. Crustaceans, like fiddler crabs (genus Uca), are particularly adept at changing their colour and have been the focus of numerous studies. However, few of these studies have attempted to quantitatively describe the individual variation in colour and patter...

The ecological effects of global climate changes include shifts of species' distribution and changes in migration strategies and phenotype. Colour polymorphism, which can be envisaged as a species' evolutionary response to alternating conditions or to a wide range of habitats, may be affected by climate changes as well. The scops owl (Otus scops) shows two main colour morphs, dark- and pale-red...

Vision based recognition systems learn the appearance of given objects using images. These objects can be recognised and localised in other images after camera motion and illumination changes. The goal of this work is to improve the ability of such systems to recognise objects after illumination changes. Recognition systems usually reduce the amount of image data used for recognition by detecti...

have also played a role in the evolution of host genomic regulatory complexity. At each end of the ERV genome are long terminal repeats (LTRs), which contain regulatory sequences that can alter the expression, splicing, and polyadenylation of those host genes located near the ERV insertion site. LTRs regulate the cell type that the virus replicates in by controlling its expression, and so can b...

We acquire a great deal of information about the world about us by perceiving the colour of objects. We can manage without colour, but certain tasks can become rather difficult telling ripe from unripe fruits, or finding green tennis balls lost in grass, for example. Yet colour information is seldom used by the machine vision community, although, given the present state of image understanding t...

The study of quasar variability has long been seen as a way to understanding the structure of the central engine of active galactic nuclei, and as a means of verifying the morphology of the standard model. Much work has already been done on the statistical properties of light curves monitored in one colour, and it is now possible to use these observations to test predictions of theoretical mode...

Colour constancy is the capacity of visual systems to keep colour perception constant despite changes in the illumination spectrum. Colour constancy has been tested extensively in humans and has also been described in many animals. In humans, colour constancy is often studied quantitatively, but besides humans, this has only been done for the goldfish and the honeybee. In this study, we quantif...
