Invasive goldfish trigger a regime shift in experimental lake ecosystems of varying trophic state
Journal of Animal Ecology, EarlyView.The pet trade distributes exotic animals around the globe that enrich human lives. However, some pets become pests when released into the wild. This study provides experimental evidence that goldfish will negatively affect native freshwater organisms and ecosystems.

Local scour at wide bridge piers
, 2014 Laboratory data for local scour depth at the size of wide piers are presented. Clear water scour tests were performed various pier widths (0.06, 0.076, 0.102, 0.14 and 0.165 m), two type of pier shapes (circular and rectangular) and two types of uniform ...

Cuttings, Combings, Fettlings and Flock: Gender and Australian Wool ‘Waste’, 1900–1950
Gender &History, EarlyView.ABSTRACT As Australia's wool industry produced vast amounts of fine fleece from the nineteenth century, the wool processing and clothes manufacturing industries generated waste – products like cuttings, combings, fettlings and flock. Salvaged and then sold to waste merchants, these and other materials had a second life.

International Journal of Urban and Regional Research, EarlyView.Abstract Waste‐to‐biofuel (WTB) programs have gained popularity as a municipal circular economy and an emissions reduction strategy. The upgrading of biofuels to renewable natural gas (RNG) has drawn particular interest, as RNG can displace conventional fossil fuels in any existing natural gas end use and be delivered through existing pipeline ...

REPAIR AND RECONSTRUCTION FOR URBAN COMMONING: The Making of the Liberated Spaces in Naples
International Journal of Urban and Regional Research, EarlyView.Abstract Commoning requires repair. Where capitalist logics of accumulation, enclosure and exclusion produce abandoned space through the city, urban commoners remake that space to serve the needs of inhabitants. Without hiding the paradoxes and risks of repair, based on years‐long ethnography in the Liberated Spaces in Naples, Italy, we demonstrate how
