Abstract:
... The state of global freshwater ecosystems is increasingly parlous with water resource development degrading high-conservation wetlands. Rehabilitation is challenging because necessary increases in environmental flows have concomitant social impacts, complicated because many rivers flow between jurisdictions or countries. Australia's Murray-Darling Basin is a large river basin with such problems en ...

Abstract:
... Colloff et al. in Marine and Freshwater Research (http:dx.doi.org/10.1071/MF14067) examined time-series data for flow-dependent vegetation, invertebrates, fish, frogs, reptiles and waterbirds in the Murray–Darling Basin, 1905–2013. They concluded that temporal patterns fluctuated, declining during droughts and recovering after floods. They suggested that major changes in land use in the late 19th ...

Key issues with defining reference condition for stream bioassessment are (1) equivocal definitions of ‘minimally disturbed’ pressure criteria and wide-ranging approaches to site selection, (2) highly modified regions where near-pristine areas do not exist, leading to management decisions based on inconsistent and unquantified benchmarks and (3) costly field campaigns associated with ‘extensive sp ...

Abstract:
... Otoliths are calcium carbonate biomineralisates in the inner ear of teleost fishes. Otoliths of the saccule (sagittae) are known to show species-specific (or even population-specific) contour differences and, thus, are regularly used in fisheries management for stock identification. However, the other two otolith types from the utricle (lapilli) and lagena (asterisci) are typically neglected in st ...

Abstract:
... Trophic linkages within a coral-reef ecosystem may be difficult to discern in fish species that reside on, but do not forage on, coral reefs. Furthermore, dietary analysis of fish can be difficult in situations where prey is thoroughly macerated, resulting in many visually unrecognisable food items. The present study examined whether the inclusion of a DNA-based method could improve the identifica ...

Abstract:
... The behaviour and growth of captive spiny lobsters (Panulirus argus) under and not under the risk of predation was investigated in four 9-m2 sea enclosures: two 'predator enclosures' (P1 and P2) into which one predator, the triggerfish Balistes vetula, was introduced; and two 'non- predator enclosures' (NP1 and NP2). Each enclosure contained a 1-m2 artificial shelter, and lobsters were provided wi ...

Comparisons are made with those of individuals remaining in coastal waters and during two earlier periods in the estuary when plant biomass differed markedly. P. octolineatus start entering the Peel–Harvey Estuary in mid-summer, so ...

In these habitats, they are considered keystone species – modifying physical and biological habitats through their foraging and predation. Here, we quantify the effects of bioturbation by rays on sand flats of Ningaloo Reef lagoon in Western Australia. We measured the dai ...
