Behavioural Ecology of Large Tuna
… for stressor impacts. However, understanding behavioural responses requires monitoring at temporal resolutions matching the biological processes of interest, from sub-second events to seasonal strategies. Accelerometers uniquely capture behaviour across this breadth: high-frequency sampling …

Behavioural Ecology of Lake Trout: From Movement Ecology to Bioenergetics
… and the population bioenergetics. Similarly, the behavioural decisions of organisms are influenced and regulated by abiotic and biotic variables. For example, in temperate aquatic organisms such as fish, habitat use is limited by environmental conditions such as temperature and dissolved oxygen …

Anthropogenic influences on the behavioural ecology of urban vervet monkeys
… Understanding an animal’s ability to adapt behaviourally to urban challenges is necessary to provide guidance for human-wildlife management plans. This thesis focuses broadly on the behavioural ecology of the adaptive, generalist vervet monkey (Chlorocebus pygerythrus). We use an integrative …

Behavioural ecology of lesser sheathbills Chionis minor at Marion Island
… 37°45'E) and the ways in which their feeding ecology, breeding biology and social behaviour were adapted to existence on a sub-Antarctic island were assessed. The birds' reproductive output and post-fledging survival rates were estimated and probable factors limiting the population examined. …

Behavioural ecology of Peregrine and Lanner falcons in South Africa
The Peregrine Falcon Falco peregrinus is a specialized predator of birds. It occurs almost worldwide but is generally uncommon. In many areas, it is sympatric with one of a complex of similar, less specialized, congeneric species (subgenus Hierofalco, the desert falcons). Peregrine density and …

Behavioural ecology of the Redbilled Woodhoopoe Phoeniculus purpureus in South Africa
… data were gathered in addition to detailed behavioural observations of 54 woodhoopoe flocks. The following experimental manipulations were performed: (1) breeders were removed from flocks to (a) monitor dispersal patterns and restructuring of flocks; and, (b) observe behavioural reactions by …

Population genetics, behavioural ecology and management of the Greywing Francolin Francolinus africanus
… study investigates the population genetics and behavioural ecology of the Greywing Francolin, Francolinus africanus, and identifies factors which influence the distribution and abundance of this important gamebird. It also develops scientifically sound management strategies which should allow …

Revealing the behavioural ecology of the elusive hairy-eared dwarf lemur (Allocebus trichotis)
… a one year study. Our aim was to clarify the behavioural ecology of the species and in particular to determine habitat use, social organisation and seasonal activity cycle. We conducted field work between January and December 2007 in the Analamazaotra Special Reserve, Andasibe, central eastern …

The behavioural ecology of modern families: a longitudinal study of parental investment and child development
In recent decades, behavioural ecologists have contributed to our understanding of the family through extensive studies of animal and traditional human populations. This research emphasises the importance of sibling competition for parental resources and adaptive patterns of biased parental care. …

Behavioural ecology of the black-flanked rock-wallaby (Petrogale lateralis lateralis): Refuge importance in a variable environment
… into its former range, little was known of the behavioural ecology of this species. Fox control in the 1980s and 1990s resulted in population increases of rock-wallabies on several reserves in the central wheatbelt of WA. However, recently these populations have rapidly declined despite …

Behavioural ecology of the greater bilby (Macrotis lagotis) and conservation tool development in a semi-wild sanctuary
… scarcity of information on their behaviour and ecology prevents informed-management. By intensively studying a population of bilbies both prior to, and following reintroduction, and subsequent reinforcements to a fenced sanctuary, I aimed to (1) advance knowledge of bilby behaviour and examine …

Behavioural ecology of sympatric lemur species Lemur catta and Eulemur sp. In forest fragments, south-eastern Madagascar
… and distribution of native ring-tailed lemurs. Behavioural observations were conducted from September 2008 to December 2009; lemur population survey was conducted from 2005 to 2009. Behavioural sampling methods include scan group sampling, focal animal sampling and ad libitum of social behaviour …
