Abstract: Intensification and expansion of agriculture is one of the most pressing concerns for biodiversity conservation. Amphibian and reptile communities can be particularly sensitive to land-use change; therefore, understanding how land use and agricultural practices influence these communities in areas under increasing agricultural pressure is prudent. Over 10 yr, we sampled amphibian and reptile communities in and around 18 man-made ponds set within an agricultural/forest matrix on a military installation in western Tennessee. Ponds had either cattle access or were cattle restricted and had different surrounding land uses (forest, pasture, row crops, and industrial development). We used Akaike information criterion, corrected (AICc), model selection and nonmetric multidimensional scaling (NMDS) to assess how land-cover and pond characteristics influence amphibian and reptile richness, diversity, and community structure. Our results indicate that, despite reduced water quality, amphibian diversity was higher in ponds with cattle access, though this is likely influenced by surrounding forest, pasture, and row-crop cover. Pond permanence was important in shaping amphibian community structure and is a key factor in determining amphibian richness. We did not find any link between land cover and cattle access on reptile richness or diversity, though reptile community structure was influenced by cattle access, pasture, and row-crop cover.

Abstract: Wildlife tourism, including tourism involving large predators, is a rapidly growing industry that can generate many conservation and economic benefits. Monetary values can be derived for populations of large predators, and even individuals, on the basis of how much money tourists spend to see and interact with these awe-inspiring animals, but valuation studies only exist for a few groups of species. To help fill this gap we quantified the monetary value of crocodilians that are the focus of a wildlife tourism business in South America, the first time such a value has been calculated for crocodilians. We also compared the monetary values we derived with the monetary values of other crocodilians harvested in the hunting and farming industries during the same time period (2009–2014). We found mean minimum and maximum gross values of individual crocodilians per year as part of wildlife tourism were $422.00 USD and $566.67 USD, respectively, both higher than the mean gross value of individual crocodilians per year across hunting and farming industries ($300.29 USD). Individual crocodilians that were recaptured multiple times as part of wildlife tourism activities reached a peak value of $2700.00 USD. Thus, our study demonstrates that wildlife tourism can create substantial monetary incentives for local communities that coexist with crocodilians to work toward conservation goals. We conclude that wildlife tourism focused on crocodilians should be viewed as part of a larger strategy for conserving threatened populations, one that may include partners in the farming and hunting industries as well.
