Sources, Sinks and Sustainability

Source-sink theories offer an easy but robust framework for realizing how the styles, tactics and dynamics of ecological platforms range and engage over area and time. Integrating a number of learn fields, together with inhabitants biology and panorama ecology, this e-book provides the most recent advances in source-sink theories, equipment and functions within the conservation and administration of common assets and biodiversity.

Application of Threshold Concepts in Natural Resource Decision Making

Typical source managers face a fancy decision-making atmosphere characterised through the capability prevalence of fast and abrupt ecological switch. those abrupt alterations are poorly accommodated via conventional ordinary source making plans and decision-making procedures. As reputation of threshold procedures has elevated, modern versions of ecological platforms were converted to higher characterize a broader variety of ecological process dynamics.

Example text

This study was undertaken over the period 1994–1997 in the Wet Tropics region and 1994–2003 in south-eastern Queensland. It involved quantitative sampling of fish assemblages at 416 locations, 959 separate samples (location and sampling occasions) and the collection of over 199 000 individual fish from 68 species (almost all of which were returned alive to the water at the site of collection). January to March, followed by a second minor peak in discharge between April and July as a result of northern penetration of low-pressure temperate weather systems [1095].

Wet seasons fail regularly in this region leading to substantial year-to-year variation. The CV of annual flow in the Burdekin River itself exceeds 100% whereas in some tributary systems, particularly in the south-west, annual flows may be even more variable [1089]. In contrast to the perennial flow regimes typical of the Wet Tropics region, the flow regimes of rivers of central Queensland are typified by long periods of very little flow occasionally punctuated by extreme flood events. The flow regimes of rivers in south-eastern Queensland are different to that described for rivers further north.
