How does behavior in the social and economic systems affect the ecological system
? Are current policies eroding, or maintaining, the resilience of SESs?" (Allison and Hobbs, 2004).
Mountain lion use of elevation ranges ([chi square] = 0.002, df = 2, P = 0.9991), ecological systems
([chi square] = 9.354, df = 4, P = 0.0528), and fine-scale terrain ruggedness classes ([chi square] = 1.622, df = 4, P = 0.8047) did not differ significantly from availability.
Today, the greenhouse gases and damage to forests and other ecological systems
that naturally sequester carbon generated by the economy's massive throughput of energy and materials has destabilized our planet's climate.
Common and Stagl state that environmental economics concerns itself with the economy's insertions into the environment, and with problems of environmental pollution: ecological economics is about the interactions between economic systems and ecological systems
, (12) treating individual preferences neither as sovereign, nor as the only source of normative criteria (there can be an ethical basis for comparing, evaluating and seeking to change tastes).
The institutional rules shape the relationship among managers, users, and ecological systems
. If the system is mapped using only ecological characteristics, then managers may not account for human responses to change, such as changing decisions about whether or how much to fish as fishing quality changes.
Among the topics are impulse synchronization for a reaction-diffusion system, monotone traveling wave solution for delayed reaction-diffusion equations, irrational-based cryptosystems, one-dimensional cellular automata with nearest-nearest neighborhoods, chaos and control in nonlinear dynamic models of ecological systems
, and fractal characteristics of the particle-size distribution function for modified brown coal.
One of the core issues and concerns of the modern conservation movement is the concept of 'sustainability', the ability of the environment to sustain and maintain its ecological systems
for both flora and fauna.
It is pathetic to hear national and international politicians bickering about the economy and how major change will disrupt our economic systems when maintaining these economic systems will entirely disrupt the ecological systems
that are necessary for our existence.
Considering our rising population and declining ecological systems
, it's imperative that we teach people to live simply.
An ecological systems
approach to examining risk factors for early childhood overweight: findings from the UK Millennium Cohort Study.
Finally, Schlosberg argues that justice concerns not only individuals but also collectivities--that is, social groups and ecological systems
"Ecologists are increasingly realizing that these links can have profound influences on the long-term dynamics of ecological systems
