This paper reviews developments in our understanding of the state Antarctic and Southern Ocean climate its relation to global system over last few millennia. Climate this earlier periods has not been stable, as evidenced by occurrence abrupt changes atmospheric circulation temperature recorded ice core proxies for past climate. Two most prominent change events are characterized intensification circumpolar westerlies (also known Annular Mode) between ∼6000 5000 years ago since 1200–1000 ago....
Abstract Acoustic telemetry is a principle tool for observing aquatic animals, but coverage over large spatial scales remains challenge. To resolve this, Australia has implemented the Integrated Marine Observing System’s Animal Tracking Facility which comprises continental-scale hydrophone array and coordinated data repository. This national acoustic network connects localized projects, enabling simultaneous monitoring of multiple species ranging from 100 s meters to 1000 kilometers. There...
Our ability to predict species responses environmental changes relies on accurate records of animal movement patterns. Continental-scale acoustic telemetry networks are increasingly being established worldwide, producing large volumes information-rich geospatial data. During the last decade, Integrated Marine Observing System's Animal Tracking Facility (IMOS ATF) a permanent array receivers around Australia. Simultaneously, IMOS developed centralised national database foster collaborative...
Researchers hoping to elucidate the behaviour of species that aren’t readily observed are able do so using biotelemetry methods. Accelerometers in particular proving particularly effective and have been used on terrestrial, aquatic volant with success. In past, behavioural modes were detected accelerometer data through manual inspection, but developments technology, modern accelerometers now record at frequencies make this impractical. light this, some researchers suggested use various...
The tagging of aquatic and semi-aquatic animals with acoustic transmitters their detection by passive underwater receivers has gained huge popularity over the past decade. This technology offers researchers opportunity to monitor finite- broad-scale movements multiple individuals many years; however, sheer scale spatial complexity these datasets are often beyond capabilities routine database spread-sheet applications. In present paper, we describe software (V-Track) that greatly facilitates...
Animal-borne telemetry has revolutionized our ability to study animal movement, species physiology, demography and social structures, changing environments the threats that animals are experiencing. While there will always be a need for basic ecological research discovery, current conservation crisis demands we look more pragmatically at data required make informed management decisions. Here, define framework distinguishes how using devices can influence conservation. We then discuss two...
Intertidal habitats provide important feeding areas for migratory shorebirds. Anthropogenic developments along coasts can increase ambient light levels at night across adjacent inter-tidal zones. Here, we report the effects of elevated nocturnal upon foraging strategy a shorebird (common redshank Tringa totanus) overwintering on an industrialised estuary in Northern Europe. To monitor behaviour full intertidal area, individuals were located by day and using VHF transmitters, was inferred...
1. The estuarine crocodile (Crocodylus porosus) is the world's largest living reptile. It predominately inhabits freshwater and habitats, but widespread geographic distribution throughout oceanic islands of South-east Pacific suggests that individuals undertake sizeable ocean voyages. 2. Here we show adult C. porosus adopt behavioural strategies to utilise surface water currents during long-distance travel, enabling them move quickly efficiently over considerable distances. 3. We used...
Over the past 15 years, integration of localised passive telemetry networks into centralised data repositories has greatly enhanced our ability to monitor presence and movements highly mobile migratory species. These large-scale are now generating big data, allowing meta-analyses across multiple species, locations, temporal scales. Broad-scale comparisons animal movement metrics constrained by use diverse analytical techniques among researchers. Accordingly, there is a need for tool-set...
The estuarine crocodile (Crocodylus porosus) is the apex-predator in waterways and coastlines throughout south-east Asia Australasia. C. porosus pose a potential risk to humans, management strategies are implemented control their movement distribution. Here we used GPS-based telemetry accurately record geographical location of adult during breeding nesting season. purpose study was assess how distribution may be influenced by localised social conditions. During breeding, females (2.92±0.013...
Active metabolic suppression in anticipation of winter conditions has been demonstrated species mammals, birds, reptiles and amphibians, but not fish. This is because the reduction rate fish directly proportional to decrease water temperature they appear be incapable further suppressing their independently temperature. However, Antarctic (Notothenia coriiceps) unusual it undergoes irrespective We assessed seasonal ecological strategy by monitoring swimming activity, growth, feeding heart...
Summary Distinguishing specific behavioural modes from data collected by animal-borne tri-axial accelerometers can be a time consuming and subjective process. Data synthesis further inhibited when the acceleration cannot paired with corresponding mode through direct observation. Here we explored use of tame surrogate (domestic dog) to build classification module, then used that module accurately identify quantify within other individuals/species. Tri-axial were recorded domestic dog whilst...
Improvements in telemetry technology are allowing us to monitor animal movements with increasing accuracy, precision and frequency. The increased complexity of the data collections, however, demands additional software programming skills process, store disseminate datasets. Recent focus on availability has also heightened need for sustainable management solutions ensure integrity provide longer term access. In last ten years, a number online facilities have been developed archiving,...
Abstract Delineation of population structure (i.e. stocks) is crucial to successfully manage exploited species and address conservation concerns for threatened species. Fish migration associated movements are key mechanisms through which discrete populations mix thus important determinants structure. Detailed information on fish becoming more accessible advances in telemetry analysis methods however such not yet used systematically stock assessment. Here, we described how detections...
This study tests the hypothesis that rainbow trout (Oncorhynchus mykiss) compensate for metabolic cost of dietary Cu exposure by reducing swimming activity at particular times during diel cycle. Fish were exposed to excess three months (726 mg Cu·kg 1 dry weight) and simultaneously oxygen consumption (MO 2 ) spontaneous measured. Rhythmicity in was examined videorecording fish behaviours 48 h. Standard rate estimates (R S 7.2 8.7 mmol O ·kg ·h (15°C) measured control Cu-exposed fish,...

The Wilms' tumour suppressor protein WT1 plays a central role in the development of kidney and also other organs. can act as transcription factor with highly context-specific activator repressor functions. We previously identified Brain Acid Soluble Protein 1 (BASP1) transcriptional cosuppressor that block activation function WT1. BASP1 are co-expressed during nephrogenesis both proteins ultimately become restricted to podocyte cells adult kidney. Here, we have analysed WT1/BASP1 complex...

Osmoregulation euryhaline is achieved through the control integration various organs (kidney, rectal gland liver) response to changes environmental salinity. However, little known regarding mechanisms ion transport gills how they affected by osmoregulatory challenges. This study was conducted gain insight into branchial acid-base regulatory C. leucas...

In recent years, there has been significant investment in collaborative e-infrastructures to support biotelemetry research. Whilst these are rapidly growing size and sophistication, the current lack of standards for reporting documenting data collected by animal-borne telemetry devices is hampering their effectiveness. Here, we demonstrate why severely complicating process those developing maintaining biotelemetry-related e-infrastructures, provide suggestions as how issue may be resolved....
