Small freshwater ponds host diverse and vulnerable biotic assemblages but relatively few conspicuous, specially protected taxa. In Europe, the amphibians Triturus cristatus and Pelobates fuscus are among a few species whose populations have been successfully restored using pond restoration and management activities at the landscape scale. In this study, we explored whether the ponds constructed...
Landscape scale conservation planning efforts have been in place for the past several decades to maintain biodiversity. Objectives of past efforts have been to identify areas to create reserves based on species diversity, land ownership, and landscape context. Risk analysis has not often been included in these spatial analyses. Datasets such as the Southwest Regional Gap Analysis (SWReGAP) are ...
It is expected that more accounting conservation (environmental uncertainty) reduces manager optimism. Prior research, however, has struggled to establish this relation empirically. Moreover, some evidence points to the possibility that the manager optimism is lower for firms with more accounting conservation. In this paper, the author examine the link between accounting conservation, environme...
Shark conservation has become a focus of current international conservation efforts. However, the misunderstanding of sharks and their negative public portrayal may hinder their conservation. More importantly, the consumption of shark fin, which is very common in Chinese cultures, poses a significant threat to sharks. Hong Kong has long been the world's largest shark fin trading center. Shark c...
Biodiversity is the basis for ecosystem goods and services that provide for human survival and prosperity. With a rapidly increasing human population and its demands for natural resources, landscapes are being fragmented, habitats are being destroyed, and biodiversity is declining. How can biodiversity be effectively conserved in the face of increasing human pressures? In this paper, I review c...
The challenges to execute wildlife conservation projects successfully have become more complex as anthropogenic changes continue to stress the planet, changing wild lands. As the wild becomes less so, more species are placed in captivity to improve their chances of long-term survival, while concurrently management (and medicine) for free-ranging wildlife has become increasingly important. A var...
Success ofwildlife conservation projects is determined by a suite of biological and economic factors. Donor and public understanding of the economic factors is becoming increasingly central to the longevity of funding for conservation efforts. Unlike typical economic evaluation, many costs and benefits related to conservation efforts are realised in nonmonetary terms. We identify the types of b...
Globally, particularly in developing countries, hydroelectricity production and economic growth occur together with ecosystem/biodiversity conservation in watersheds. There is a relationship between hydroelectricity production and ecosystem/biodiversity conservation in watersheds, centering on the supply and demand for ecosystem services of river water flow regulation and sediment retention. He...
A common justification for developing wildlife tourism attractions is that they help to secure long-term conservation of wildlife and wildlife habitats. Managers and guides often highlight their role in protecting wildlife and its habitat, yet little is known about the interests, needs and preferences of the tourists who participate in such activities – how aware are they of conservation issues...
