Seabirds are among the most threatened groups of species. Seabirds are an important component of both marine and island ecosystems, and thus their conservation is inextricably linked with marine and island conservation. Invasive mammals are the major drivers of extinction and ecosystem change on islands and are the primary threat to seabirds. Three types of evidence suggest that the removal of ...
Kane County is located on the western fringe of the greater Chicago metropolitan area. Development pressures there have caused rapid increases in land consumption and property values. The county’s Forest Preserve District is actively purchasing land for conservation, but it is important to understand the long-term costs associated with current conservation goals. We developed 18 future scenario...
Modern architecture has vital impact in Nigerian architecture even though there are somesocio-cultural and religious factors and elements of traditional architecture and use of traditional materials andprinciples of design that still exist. This paper will be discussing on how modern architecture failed in the aspectthe of conservation and restoration of palace buildings which are the focal poi...
The extent to which current landscapes deviate from the historical range of natural variability (RNV) is a common means of defining and ranking regional conservation targets. However, climate-induced shifts in forest composition may render obsolete restoration strategies and conservation targets based on historic climate conditions and disturbance regimes. We used a spatially explicit forest ec...
Simple rules can guide whether land- or ocean-based conservation will best benefit marine ecosystems
Coastal marine ecosystems can be managed by actions undertaken both on the land and in the ocean. Quantifying and comparing the costs and benefits of actions in both realms is therefore necessary for efficient management. Here, we quantify the link between terrestrial sediment runoff and a downstream coastal marine ecosystem and contrast the cost-effectiveness of marine- and land-based conserva...
The historical area of bottomland hardwood forest in the Mississippi Alluvial Valley has been reduced by >75%. Agricultural production was the primary motivator for deforestation; hence, clearing deliberately targeted higher and drier sites. Remaining forests are highly fragmented and hydrologically altered, with larger forest fragments subject to greater inundation, which has negatively affect...
