Smallholder-dominated agricultural mosaic landscapes are highlighted as model production systems that deliver both economic and ecological goods in tropical agricultural landscapes, but trade-offs underlying current land-use dynamics are poorly known. Here, using the most comprehensive quantification of land-use change and associated bundles of ecosystem functions, services and economic benefit...

A definite shift is underway from an environmental protection regulatory stance to a view of natural systems as essential components of human society's life support system. In addition, before the agricultural and industrial revolutions, arguably, human society's entire life support system was ecological. With increased human population size and the redistribution of people to urban areas, huma...

Many physical diseases have been reported to be associated with psychosocial factors. In these diseases, assessment relies mainly on subjective symptoms in natural settings. Therefore, it is important to assess symptoms and/or relationships between psychosocial factors and symptoms in natural settings. Symptoms are usually assessed by self-report when patients visit their doctors. However, self...

Ecological momentary assessment and/or experience sampling methods are increasingly used in health studies to study subjective experiences within changing environmental contexts. In these studies, up to 30 or 40 observations are often obtained for each subject. Because there are so many measurements per subject, one can characterize a subject's mean and variance and can specify models for both....

Global warming, which is caused by over consumption of fossil energy during economic development in human society, threatens global ecological balance, tampers social and economic development, imperils energy security, ecological safety, water and food safety, and endangers the entire human race. Low carbon economy is a new economic development model based on low energy consumption, low polluti...

very little information exists in regards to the control options available for potato flea beetles, epitrix spp. this short review covers both chemical and ecological options currently available for control of epitrix spp. synthetic pyrethroids are the weapon of choice for the beetles. however, the impetus in integrated pest management is to do timely (early-season) applications with something ...

In this paper, the overall ecological and environmental sustainability in the Cing-Jing region in Taiwan is examined. As land use and cover change has been found to be an important analysis method, an emergy ecological footprint model was applied and the eco-security assessed to ensure authorities maintain a balance between ecological preservation and tourism development. While the ecological e...

The classical view of ecological systems has been one that assumes a state of equilibrium and stability; this is encapsulated in the ‘balance of nature’ paradigm. Over the last 30 years ecologists and biogeographers have rejected the view that ecological systems are inherently stable or at some sort of equilibrium. Instead a nonequilibrium view, emphasizing the role of chance events such as dis...
