Shows what you know... so stop being a troll, im fed up of reading posts where you get nasty claming you know it all and noone else knows squat.hooded_vixen said:im very suspicious when people think that any captive bred animal needs no uv
As part of an overall decline in biodiversity, amphibian populations throughout the world are disappearing. There are a number of potential causes for these declines, including those related to environmental changes such as increasing ultraviolet-B (UV-B) radiation due to stratospheric ozone depletion. UV-B radiation can kill amphibian embryos or can cause sublethal effects that can harm amphibians in later life stages.
some species more able to cope with exposure to UV-B than others. Unfortunately, the defense mechanisms of many species may not be effective against increasing persistent levels of UV-B radiation that have only been present for the past several decades due to human-induced environmental damage. Moreover, we predict that persistent UV-B–induced mortality and sublethal damage in species without adequate defenses could lead to changes in community structure
We review studies including laboratory and field approaches on damage to amphibians from UVB exposure. Field studies in which embryos were exposed to natural sunlight or sunlight with UVB removed have shown conflicting results: some show increased embryonic mortality after UVB exposure, whereas others show that current levels of UVB are not detrimental to amphibian embryos
I have also read that high levels of UVB light (such as that given out by your bulb) can damage eyesight of nocturnal speciesField experiments have been used with increasing frequency to investigate ultraviolet radiation as one of the potential factors contributing to these declines. Results from field experiments illustrate that hatching success of eggs is hampered by ultraviolet radiation in a number of species, while other species appear to be unaffected. Continued mortality in early life-history stages may ultimately contribute to a population decline.
