The term ‘‘habitat restoration’’ appears frequently in conservation and landscape management documents but is often poorly articulated. There is a need to move to a clearer and more systematic approach to habitat restoration that considers appropriate goals linked to target species or suites of species, as well as the ecological, financial, and social constraints on what is possible. Recommenda...
OBJECTIVE To analyze left ventricle performance after myocardial revascularization associated to ventricular geometrics restoration by "pacopexy" in schemic myocardiopathy patients with significant ventricular dysfunction in whom ventricular restoration was obtained through special technique. METHODS Myocardial revascularization associated to ventricular geometrics restoration through special...
Planners are being called on to prioritize marine shorelines for conservation status and restoration action. This study documents an approach to determining the management strategy most likely to succeed based on current conditions at local and landscape scales. The conceptual framework based in restoration ecology pairs appropriate restoration strategies with sites based on the likelihood of p...
Oral lichenoid reactions are considered variants of oral lichen planus and may be regarded as a disease by itself or as an exacerbation of an existing oral lichen planus by the presence of medication or dental materials. They represent a type IV hypersensitivity reaction and most commonly affect the oral mucosa in direct contact with an amalgam restoration. Oral lichenoid reactions can cause si...
Billions of dollars are now spent annually in the United States and Europe for spatially delineated environmental services such as agricultural landscape management and river restoration programs, yet little is known about the spatial distribution of the benefits from these policies. This paper develops a framework for recovering information on this question from the spatial pattern of votes ca...
Increasing demands for livelihood resources in tropical rural areas have led to progressive clearing of biodiverse natural forests. Restoration of abandoned farmlands could counter this process. However, as aims and modes of restoration differ in their ecological and socio-economic value, the assessment of achievable ecosystem functions and benefits requires holistic investigation. Here we comb...
There is increasing interest in developing better predictive tools and a broader conceptual framework to guide the restoration of degraded land. Traditionally, restoration efforts have focused on re-establishing historical disturbance regimes or abiotic conditions, relying on successional processes to guide the recovery of biotic communities. However, strong feedbacks between biotic factors and...
English wood pastures have become a target for ecological restoration, including the restoration of pollarded trees and grazing animals, although pigs have not been frequently incorporated into wood pasture restoration schemes. Because wood pastures are cultural landscapes, created through the interaction of natural processes and human practices, a historical perspective on wood pasture managem...
This paper deals with protecting all-optical networks (AON) from security attacks at the physical level. It firstly presents an overall high level protocol for establishment, management and on-the-fly restoration of optimal secure lightpaths established by applying constraint-based open shortest path first (OSPF) source routing using proposed security databases of components. Secondly it presen...
over marine waters, fueled primarily by several highprofile ocean commission reports and news coverage of coastal dead zones (POC 2003; USCOP 2004; MSNBC 2005). Special attention has been paid to coastal fisheries, generating heated debates over the need to relieve pressure on populations through harvesting restrictions and habitat set-asides and to reduce non-point source pollution that broadl...
