Can science save the giant panda (Ailuropoda melanoleuca)? Unifying science and policy in an adaptive management paradigm…Here, we review recent developments in giant panda conservation science and propose a strategic plan for moving panda conservation forward…. Specific threats, such as habitat destruction, anthropogenic disturbance and fragmented nonviable populations, need to be addressed simultaneously by researchers, managers and policy-makers working in concert to understand and overcome these obstacles to species recovery. With the backing of the Chinese Government and the conservation community, the giant panda can become a high-profile test species for this much touted, but rarely implemented, approach to conservation management….
Got hybridization? A multidisciplinary approach for informing science policy...Developing sound science-based conservation policy that addresses hybridization requires cross-disciplinary social-science and life-science research to address the following two questions: (1) How do human decisions with regard to species protection, trade, transportation, land use, and other factors affect the opportunities for, and rates of hybridization between, rare species and more common relatives? and (2) How do the positive or negative perceived values regarding hybrids and hybrid-derived individuals compare with values regarding their nonhybridized counterparts from social, cultural, economic, and environmental perspectives...?
Informing species conservation at multiple scales using data collected for marine mammal stock assessmentsBackground Conservation planning and the design of marine protected areas (MPAs) requires spatially explicit information on the distribution of ecological features. Most species of marine mammals range over large areas and across multiple planning regions. The spatial distributions of marine mammals are difficult to predict using habitat modelling at ecological scales because of insufficient understanding of their habitat needs, however, relevant information may be available from surveys conducted to inform mandatory stock assessments. Methodology and Results We use a 20-year time series of systematic aerial surveys of dugong (Dugong dugong) abundance to create spatially-explicit models of dugong distribution and relative density at the scale of the coastal waters of northeast Australia (∼136,000 km2). We interpolated the corrected data at the scale of 2 km * 2 km planning units using geostatistics. Planning units were classified as low, medium, high and very high dugong density on the basis of the relative density of dugongs estimated from the models and a frequency analysis. Torres Strait was identified as the most significant dugong habitat in northeast Australia and the most globally significant habitat known for any member of the Order Sirenia. The models are used by local, State and Federal agencies to inform management decisions related to the Indigenous harvest of dugongs, gill-net fisheries and Australia's National Representative System of Marine Protected Areas. Conclusion/Significance In this paper we demonstrate that spatially-explicit population models add value to data collected for stock assessments, provide a robust alternative to predictive habitat distribution models, and inform species conservation at multiple scales.
Seasonal competition between sympatric species for a key resource: Implications for conservation managementCompetition often occurs between two or more sympatric species that use similar ecological niches. During competition, a superior species may exclude the competitor from parts of its fundamental niche or make it go extinct....
