It is generally perceived that biodiversity better protected from human activities after an area designated as a area. However, we found this common perception was not true in Wolong Nature Reserve (southwestern China), which established 1975 “flagship” for the world-renowned endangered giant pandas. Analyses of remote sensing data pre- and post-establishment periods indicate reserve has become more fragmented less suitable panda habitation. The rate loss high-quality habitat reserve's...

AbstractTraditional approaches to studying human–environment interactions often ignore individual-level information, do not account for complexities, or fail integrate cross-scale cross-discipline data and methods, thus, in many situations, resulting a great loss predictive explanatory power. This article reports on the development, implementation, validation, results of an agent-based spatial model that addresses such issues. Using from Wolong Nature Reserve giant pandas (China), simulates...

Fanjinshan National Nature Reserve (FNNR) is a biodiversity hotspot in China that part of larger, multi-use landscape where farming, grazing, tourism, and other human activities occur. The steep terrain persistent cloud cover pose challenges to robust vegetation land use mapping. Our objective develop satellite image classification techniques can reliably map forest while minimizing the issues, provide basis for long-term monitoring. Multi-seasonal Landsat composites elevation ancillary...

We discuss institutional reforms to China’s protected area management. Currently (as elsewhere), areas suffer fragmented management, lack of a comprehensive classification, inadequate coverage biodiversity and ecosystem services, divided, inconsistent legislation. recommend establishing new system management that can address past difficulties by using ongoing as unprecedented opportunities. Establishing is the major strategy for conserving worldwide [1.Watson J.E. et al.The performance...

To counter their widespread loss, global aspirations are for no net loss of remaining wetlands [1Conservation FoundationProtecting America's Wetlands: An Action Agenda: The Final Report the National Wetlands Policy Forum. Conservation Foundation, 1988Google Scholar]. We examine whether this goal alone is sufficient managing China's wetlands, they constitute 10% world's total. Analyzing wetland changes between 2000 and 2015 using 30-m-resolution satellite images, we show that expanded by...

Existing influenza surveillance in the United States is focused on collection of data from sentinel physicians and hospitals; however, compilation distribution reports are usually delayed by up to 2 weeks. With popularity social media growing, Internet a source for syndromic due availability large amounts data.

Multiple candidates of COVID-19 vaccines have entered Phase III clinical trials in the United States (US). There is growing optimism that social distancing restrictions and face mask requirements could be eased with widespread vaccine adoption soon.We developed a dynamic compartmental model transmission for four most severely affected states (New York, Texas, Florida, California). We evaluated effectiveness coverage required to suppress epidemic scenarios when contact was return pre-pandemic...

Global biodiversity loss is largely driven by human activities such as the conversion of natural to human-dominated landscapes. A popular approach mitigating land cover change designation protected areas (e.g., nature reserves). Nature reserves are traditionally perceived strongholds conservation. However, many affected changes not only within their boundaries, but also in surrounding areas. This study analyzed habitat for giant panda (Ailuropoda melanoleuca) inside Wolong Reserve, Sichuan,...

Understorey vegetation is a critical component of biodiversity and an essential habitat for many wildlife species. However, compared to overstorey, information about understorey distribution scant, available mainly over small areas or through imprecise large area maps from tedious time-consuming field surveys. A practical approach classifying remote sensing data needed more accurate analyses estimates. As case study, we mapped the spatial bamboo in Wolong Nature Reserve (south-western China)...

Coupled human and natural systems (CHANS) are characterized by many complex features, including feedback loops, nonlinearity thresholds, surprises, legacy effects time lags, resilience. Agent-based models (ABMs) powerful for handling such complexity in CHANS models, facilitating in-depth understanding of dynamics. ABMs have been employed mostly on a site-specific basis, however. Little this work provides common infrastructure with which researchers (especially nonmodeling experts) can...
