Humpback whale (Megaptera novaeangliae) populations typically undertake seasonal migrations, spending winters in low latitude breeding grounds and summers foraging high feeding grounds. Until recently, a broad scale understanding of movement has been derived from whaling records, Discovery marks, photo identification genetic analyses. However, with advances satellite tagging technology concurrent development analytical methodologies we can now detail finer humpback movement, infer...
The humpback whales that migrate along the east coast of Australia were hunted to near-extinction in 1950s and early 1960s. Two independentseries land-based surveys conducted over last 25 years during whales’ northward migration Australian coastline havedemonstrated a rapid increase size population. In 2004 we survey migratory population as continuation theseseries surveys. methods data analysis used line with previous surveys, both for calculation absolute relative abundance.We consider...
In understanding the impact of commercial whaling, it is important to estimate mixing low latitude breeding populations on Antarctic feeding grounds, particularly endangered humpback whale Oceania. This paper estimates degree genetic differentiation among putative Oceania (New Caledonia, Tonga, Cook Islands and French Polynesia) Australia (western eastern Australia) using ten microsatellite loci mtDNA, assesses power data for a mixed-stock analysis, determines ways improve statistical future...
In this paper we employ a large new data set to examine explanations of the tendency for favourites be under-bet and longshots over-bet in recent British racetrack betting markets. We demonstrate that both demand supply side factors can explain favourite--longshot bias propose empirical tests identify influence insider trading on bias. The results suggest adverse selection problem faced by bookmakers, context bettors who may possess superior information, is capable explaining at least some observed
Abstract Existing literature has provided inconclusive evidence regarding the impact of financial performance on firm policy relating to environmental issues. In this paper, we propose that influence corporate is unlikely be monotonic but, rather, will vary with life cycle. We test hypothesis by application static and dynamic techniques panel data from UK companies. The results provide support for our hypotheses strongest in maturity stage cycle weakest rapid growth stage. Copyright © 2007...
Bookmakers have argued that person‐to‐person internet ‘betting exchanges’ represent unfair competition. In this paper we suggest that, in fact, betting exchanges brought about significant efficiency gains by lowering transaction costs for consumers. We test hypothesis using matched data on UK horse racing from and traditional media. comparison with media, find exhibit evidence of significantly lower market biases. also an information‐based model explains the well documented...
Abstract The Coorong, South Australia, is a globally significant wetland system, listed in the Ramsar Convention under number of different criteria, including its importance to waterbird populations. Based on annual censuses conducted between 2000 and 2007, spatiotemporal analyses revealed that differences community structure exist along length Coorong. This spatial diversity was also found be temporally consistent over this 8‐year period. abundance most numerically dominant bird species,...

Body mass of migrant Rufous Hummingbirds (Selasphorus rufus) on refueling stopovers increased average from 3.2 to 4.6 g over a period ranging several days 3 wk. In birds arriving with body masses below °3.5 g, the initial gain was very slow. This slow not explained by energy costs associated territory establishment or learning secure food, since it occurred even in years when nectar resources were superabundant and territoriality nearly nonexistent. Data composition indicate that up due...
Seismic surveys are widely used for exploration oil and gas deposits below the sea floor. Despite concern they may have an impact on whale behaviour, our knowledge of marine mammal responses is limited. In first a series experiments (the last one involving full seismic array), this study tested response migrating humpback (Megaptera novaeangliae) groups to 20 cubic inch air gun. Experiments were carried out during southward migration whales along east coast Australia. Groups focally followed...
Abstract Knowledge about the movement ecology of endangered species is needed to identify biologically important areas and spatio-temporal scale potential human impacts on species. Blue whales ( Balaenoptera musculus ) are due twentieth century whaling currently threatened by activities. In Australia, they feed in Great Southern Australian Coastal Upwelling System (GSACUS) during austral summer. We investigate their movements, occupancy, behaviour, environmental drivers inform conservation...
Discovery mark tagging provided the first evidence of linkages between eastern Australian and Oceania Humpback whale breeding grounds Antarctic Area V feeding areas. Early investigation movements humpback whales in Western Pacific led to view that Balleny Islands Ross Sea were summer destinations for from Australia grounds. Recent photo-identification (ID) studies further low levels migratory interchange complex within Oceania. We report here movement three (Megaptera novaeangliae) Eastern...
Recent photo-identification and genetic studies have identified at least five discrete breeding populations in Australia Oceania: western (D), eastern (E (i)), New Caledonia (ii)), Tonga (iii)), French Polynesia the Cook Islands (F). Also evident are low levels of intermingling among consistent with degree differentiation. Photo-identification has confirmed linkages between Area V feeding areas grounds one genotype match been reported Oceania grounds. abundance estimates show strong...

ABSTRACT The effect of various anthropogenic sources noise (e.g. sonar, seismic surveys) on the behaviour marine mammals is sometimes quantified as a dose–response relationship, where probability an animal behaviourally ‘responding’ avoiding source) increases with ‘dose’ (or received level noise). To do this, however, requires definition ‘significant’ response (avoidance), which can be difficult to quantify. There also potential that ‘avoids’ not only source but vessel operating source,...
