While we generally understand the optimal ultraviolet B (UVB) environment for the growth and reproduction of female Panther Chameleons Furcifer pardalis, we do not know the relative importance of UVB irradiance and dose for optimal husbandry outcomes

We monitored daily patterns of natural ultraviolet-B (UVB) exposure (measured using the ultraviolet index [UVI]) of the Texas horned lizard (Phrynosoma cornutum) in North Central Texas. The animals were active on unpaved road surfaces on warm sunny d

Repeated observations of forest development using permanent plots can map pathways and rates of primary succession at the individual plant, the plot and the community level. This study re-measures the trees in 34 100 m2 plots that were first sampled

Montane conifers of western North America commonly colonize mineral surfaces resulting from landslides, lahars, mudflows, and rock avalanches. This colonization can include shade-tolerant conifers that may eventually dominate the forest in a pattern

Colonization of a relatively undisturbed 1915 debris flow by an upper montane coniferous forest was examined in Lassen Volcanic National Park in northern California in 1987. Seventy 100-m2 circular plots were arranged in four transects across the flo

Many streams of central Pennsylvania are polluted by sulphuric acid from coal mining operations. The most prevalent organism in these streams is an aquatic macrophyte - Eleocharis acicularis (L.) R. and S. (slender spikerush). An experiment using /su
