Описание: This book is intended for periodontal residents and practicing periodontists who wish to incorporate the principles of moderate sedation into daily practice. Comprehensive airway management and rescue skills are then documented in detail so that the patient may be properly managed in the event that the sedation progresses beyond the intended level.

Описание:
A plethora of different theories, models, and concepts make up the field of community ecology. Amid this vast body of work, is it possible to build one general theory of ecological communities? What other scientific areas might serve as a guiding framework? As it turns out, the core focus of community ecology--understanding patterns of diversity and composition of biological variants across space and time--is shared by evolutionary biology and its very coherent conceptual framework, population genetics theory. The Theory of Ecological Communities takes this as a starting point to pull together community ecology's various perspectives into a more unified whole.
Mark Vellend builds a theory of ecological communities based on four overarching processes: selection among species, drift, dispersal, and speciation. These are analogues of the four central processes in population genetics theory--selection within species, drift, gene flow, and mutation--and together they subsume almost all of the many dozens of more specific models built to describe the dynamics of communities of interacting species. The result is a theory that allows the effects of many low-level processes, such as competition, facilitation, predation, disturbance, stress, succession, colonization, and local extinction to be understood as the underpinnings of high-level processes with widely applicable consequences for ecological communities.
Reframing the numerous existing ideas in community ecology, The Theory of Ecological Communities provides a new way for thinking about biological composition and diversity.

Описание: Interactions, between competitors, predators and their prey form the foundations of community structure. This book investigates the roles parasites play in influencing these interactions, both detrimental and beneficial. This comprehensive guide is of relevance to academics, practitioners and graduates in biodiversity, conservation and population management, and animal and human health.

Описание:
This book offers one of the first detailed anthropological studies of emergent ecotopianism in urban contexts. Engaging directly with debates on urbanisation, sustainability and utopia, it presents two detailed ethnographic case studies of inner urban Australian eco-communities in Adelaide and Melbourne. These novel responses to the ecological crisis – real social laboratories that attempt to manifest a vision of the ‘eco-city’ in microcosm – offer substantial new insights into the concept and creation of sustainable urban communities, their attempts to cultivate ways of living that are socially and ecologically nourishing, and their often fraught relationship to the capitalist city beyond. These studies also suggest the opportunities and limitations of moving beyond demonstration projects towards wider urban transformation, as well as exposing the problems of accessibility and affordability that thwart further urban eco-interventions and the ways that existing projects can exacerbate issues of gentrification and privilege in a socially polarised city. Amidst the challenges of the capitalist city, climate change and ecological crisis, this book offers vital lessons on the potential of urban sustainability in future cities.

Описание: Therefore, in addition to theoretical population biology (including some original models) the book also discusses observational data from nature to show how the theoretical models give new insight and how observations give rise to new theoretical thought.

Описание: I have thus written for the pleasure derived from depicting, perhaps at times as something of an impressionist, a fascinating biotic region, a captivating land, a collection of interesting ecological problems, environmental relationships to be discerned in part, perhaps understood to some small degree, perhaps one day to be modeled mathematically.

Описание: Tropical communities are recognised as among the most species-rich and dynamic in the world. Yet far from existing as dynamic equilibria, large unpredictable disruptive events are seen as dominating the dynamics. This 1998 volume challenges the dynamic equilibrium idea further, considering timescale, innovative handling of unpredictability and evaluating species diversity.
