“…This may reflect that most detailed research has either focussed on breeding behaviour (e.g. Fukuyama et al 1988;Lemckert and Brassil 2000) or on post-breeding migrations (e.g. Lamoureux and Madison 1999;Richter et al 2001) rather than the non-breeding habitat use itself.…”

Management of threatened anurans requires an understanding of a species' behaviour and habitat requirements in both the breeding and non-breeding environments. The giant burrowing frog (Heleioporus australiacus) is a threatened species in south-eastern Australia. Little is known about its habitat requirements, creating difficulties in developing management strategies for the species.Weradio-tracked 33 individual H. australiacus in order to determine their habitat use and behaviour. Data from 33 frogs followed for between 5 and 599 days show that individuals spend little time near (<15 >m) their breeding sites (mean 4.7 days for males and 6.3 days for females annually). Most time is spent in distinct non-breeding activity areas 20-250m from the breeding sites. Activity areas of females were further from the breeding site (mean 143 m) than those of males (mean 99 m), but were not significantly different in size (overall mean 500m2; males 553m2; females 307m2). Within activity areas, each frog used 1-14 burrows repeatedly, which weterm home burrows. Existing prescriptions are inappropriate for this species and we propose protection of key populations in the landscape as a more appropriate means of protecting this species. Abstract.

“…Daily activities often include foraging for food, predator avoidance, territoriality, and searching for refuge sites (Streatfeild 1999;Lemckert & Brassil 2000;Doak 2005). The priority of these movements may depend upon environmental conditions and seasonality, such as increased time in refuge sites during periods of environmental stress, or increased territoriality during the breeding season.…”

“…The priority of these movements may depend upon environmental conditions and seasonality, such as increased time in refuge sites during periods of environmental stress, or increased territoriality during the breeding season. Most stream associated anurans congregate around water bodies for some period of the year when reproducing, although their movements during this period are largely unknown (Lemckert & Brassil 2000). In species with prolonged breeding seasons, males will usually call from stationary positions in order to attract females, and this results in inter-male spacing (Wells 1977a), which is likely maintained through territorial behaviour.…”

“…Anuran movements have been recorded anywhere from tens of metres up to several kilometres (Sinsch 1988;Berven & Grudzien 1990;Driscoll 1997;Lemckert & Brassil 2000). An analysis of 53 anuran species revealed 44% were able to disperse distances greater than one kilometre, while 7% had maximum dispersal distances greater than 10 km (Smith & Green 2005).…”

“…Lemckert and Brassil (2000) examined the short-term movements of Mixophyes iteratus, and found they were mostly restricted to an area 20 m either side of the stream. It was concluded that a 30 m riparian buffer zone was sufficient to protect the area of stream side habitat used by M. iteratus from direct disturbance.…”

Hydrological alteration has contributed to the global decline of stream frogs. Flows support stream frog reproduction, juvenile development, food resources, and maintain habitats for all life stages. At present, there is a lack of information regarding the specific water requirements necessary for the conservation of stream frogs. To address this gap, we developed a traits‐based approach that serves as a valuable tool for grouping and prioritising water‐dependent stream frog species to inform future research priorities and environmental flow design. In this study, we focussed on 53 Australian frog species and analysed eight species traits to develop water‐dependent functional groups for stream frogs. We classified frogs based on their level of water dependency using an agglomerative hierarchical clustering analysis and a systematic review of water requirements and water management threats. The distinguishing traits that determined functional groups were: tadpole body type, egg clutch type, stream breeding habitat type, and documented association with flowing water and water permanence. Our study identified two distinct water‐dependent groups: facultative stream spawners, capable of reproducing in both stream and non‐stream habitats, and obligate stream spawners, restricted solely to stream habitats. Importantly, we highlight that the obligate stream spawners are the most sensitive group to within‐channel flow alteration and should be prioritised for water management decisions in lotic environments. This study represents the first comprehensive overview of the importance of hydrology for stream frogs and identifies the critical need for additional research and validation to enhance our understanding of stream frog responses to flows regimes.
