The problem of effective assessment of risk posed by complex mixtures of toxic chemicals in the environment is a major challenge for government regulators and industry. The biological effect of the individual contaminants, where these are known, can

MDFRC item.To restore lateral connectivity in highly regulated river-floodplain systems, it has become necessary to implement localized, “managed” connection flows, made possible using floodplain irrigation infrastructure. These managed flows con

The aim of this study was to determine the dietary characteristics and mouth morphology of Othos dentex and to use these data, together with in situ observations of feeding behaviour, to elucidate how foraging and diet are optimized by this piscivoro

This study examined inter-period changes over two to three decades in the fish fauna of an urbanized estuary experiencing rapid population growth and a drying climate (Swan-Canning Estuary, Western Australia). Responses were compared at the fish comm

In soils, the microbially mediated decomposition of plant residue is a key process with wide ranging effects on ecosystem functioning and stability. Understanding the impact of contamination on this process is of high importance. We investigated the

Conservation requires decisions about which sites to protect. Choices are frequently made using distributions or occurrences of rare or endemic species, or species richness. For many assemblages, such data do not exist, may be semi-quantitative, or t

A mesocosm experiment was conducted to quantify the effects of short- (2 wk) and long- term (20 wk) exposure to acidified seawater on the structure and diversity of macrofaunal and nema- tode assemblages in 2 different sediment types. The impact of a

Demersal trawling causes chronic and widespread disturbance to the seabed in shallow shelf seas potentially leading to changes in function and trophic structure of benthic communities and with important implications for the processing of primary prod

Although avian species are known to be susceptible to infection with Mycobacterium spp. organisms, much remains unknown about the susceptibility of birds to infection with M. bovis. The objective of this current study was to determine if wild turkeys

Statistical tests for non-random associations with components of habitat or different kinds of prey require information about the availability of sub-habitats or types of prey. The data are obtained from sampling (Stage 1 samples). Tests are then con
