Improving the Utility of Artificial Shelters for Monitoring Eastern Hellbender Salamanders (Cryptobranchus alleganiensis alleganiensis)
Artificial shelters show great promise as novel, non-invasive tools for studying hellbenders, but their use thus far has faced several challenges. During initial trials in multiple river networks, artificial shelters routinely became blocked by sediment and dislodged during high stream discharge …

Effects of Land Use on Hellbenders (Cryptobranchus alleganiensis) at Multiple Levels and Efficacy of Artificial Shelters as a Monitoring Tool
… land use. In Chapter IV I examine efficacy of artificial shelters as a monitoring tool and demonstrate their potential as tool to further our understanding of mechanisms underlying demographic responses of hellbenders to land use. I synthesize my findings in Chapter V and conclude that loss of …

Methods for assessment and techniques for management of striped legless lizard Delma impar populations in South-Eastern Australia
… experiments on the species. However, the use of artificial shelters, roof tiles in this case, is cheaper, less labour intensive and less disturbing and therefore provides an adequate survey tool. Surveys conducted in spring yielded a larger number of D. impar over a shorter survey period. An …

The Ecological Ramifications of Disease and Density in the Caribbean Spiny Lobster, <i>Panulirus argus</i>
… were experimentally concentrated at sites with artificial shelters. Moreover, enhanced density does not appear to have a detrimental effect on population dynamics such as nutritional condition and short-term residency, likely due to their normal gregariousness. Thus, juvenile spiny lobsters …

Micro and macroclimate effects on reproductive performance of Common Eiders
… (microclimate) cues. By providing females with artificial shelters I tested some of the effects of microclimate on individual physiology and use of energy during incubation. Females experienced improved microclimatic conditions provided by well-sheltered nest-sites. Nest shelter conferred …
