Quantifying the vitamin D3 synthesizing potential of UVB lamps at specific distances over time
Abstract The purpose of this study was to quantify the ultraviolet B (UVB) output and in vitro previtamin D3 synthesis over time from various artificial light sources. Three incandescent lamps, T-Rex Active UVHeat 160 watt spot, T-Rex Active UVHeat 160 watt flood, and ZooMed PowerSun 160 watt flood, and two 1.2 m fluorescent lamps, Sylvania Blacklight […]
Causes of mortality in anuran amphibians from an ex situ survival assurance colony in Panama
The success of ex situ survival assurance populations as tools for amphibian conservation depends on the health and reproductive success of founder populations. Necropsy examination and histopathology of animals that die in assurance populations are useful for the identification of population-limiting disease problems and can help to direct applied research efforts in areas such as […]
