Abstract Urbanization alters the flow regime of streams, including increasing frequency and magnitude storm flows, along with reducing baseflows. An increasingly common management strategy is stormwater infiltration, which thought to reduce surface runoff recharge groundwater thus restore lost baseflows streams. Recent research has pointed considerable uncertainty on fate infiltrated stormwater...

Human activities have released large amounts of toxic organic and inorganic chemicals into the environment. Toxic waste streams threaten dwindling drinking water supplies and impact terrestrial, estuarine and marine ecosystems. Cleanup is technically challenging and the costs based on traditional technologies are exceeding the economic capabilities of even the richest countries. Recent advances...

And so the most spectacular crash of the world's most neo-liberal government ushered in the neo-liberal consensus. From now on both major contending parties in the British state accept the essential neo-liberal tenets: markets should rule under the guidance of entrepreneurs, with minimal intervention from government; taxes and public spending, and in particular the redistributive effect of dire...

Imagine having to prove everything you believe at one time. That is exactly what happened when I was asked to change the design of an Enterprise Backup System to accommodate the backup and restore needs of a new, very large system. To meet the challenge, I’d have to use three brand-new pieces of technology and push my chosen backup software to its limits. Would I be able to send that much data ...

1. Stream ecosystems are increasingly impacted by multiple stressors that lead to a loss of sensitive species and an overall reduction in diversity. A dominant paradigm in ecological restoration is that increasing habitat heterogeneity (HH) promotes restoration of biodiversity. This paradigm is reflected in stream restoration projects through the common practice of re-configuring channels to ad...

1. Due to the hierarchical organization of stream networks, land use changes occurring at larger spatial scales (i.e. the catchment) can affect physical, chemical and biological characteristics at lower spatial scales, ultimately altering stream structure and function. Anthropogenic effects on streams have primarily been documented using structural metrics such as water chemistry, channel alter...

Often simple metrics are used to summarise complex patterns in stream benthic ecology, thus it is important to understand how well these metrics can explain the finer-scale underlying environmental variation often hidden by coarser-scale influences. I sampled 47 relatively pristine streams in the central North Island of New Zealand in 2007 and (1) evaluated the local-scale drivers of macroinver...

Unchanging physicochemical conditions and nutrient sources over long periods of time in cave and karst subsurface habitats, particularly aquifers, can support stable ecosystems, termed autochthonous microbial endokarst communities (AMEC). AMEC existence is unknown for other karst settings, such as epigenic cave streams. Conceptually, AMEC should not form in streams due to faster turnover rates ...

Stormwater management strategies increasingly recognise the need to emulate the pre-development flow regime, in addition to reducing pollutant concentrations and loads. However, it is unclear whether current design approaches for stormwater source-control techniques are effective in restoring the whole flow regime, and in particular low flows, towards their pre-development levels. We therefore ...
