Agent‐based modelling of southward coastal migration by humpback whale mother–calf pods off eastern AustraliaNARA Subscribed
Humpback whales Megaptera novaeangliae encounter a variety of environmental conditions during seasonal migration between feeding grounds and breeding grounds. Relationships between environmental conditions and migratory movements are largely unknown due to a lack of oceanographic data coincident with their presence/absence. We begin to address this knowledge gap by developing a new agent‐based modelling (ABM) approach designed...
The Role of Environmental Drivers in Humpback Whale Distribution, Movement and Behavior: A ReviewOA Marine
Humpback whales, Megaptera novaeangliae , are a highly migratory species exposed to a wide range of environmental factors during their lifetime. The spatial and temporal characteristics of such factors play a significant role in determining suitable habitats for breeding, feeding and resting. The existing studies of the relationship between oceanic conditions and humpback whale ecology provide the basis for understanding impac...
Summary Crocosphaera watsonii WH 8501 is a marine unicellular cyanobacterium that fixes nitrogen primarily during the dark phase of a light–dark (LD) cycle. Circadian clocks modulate gene transcription and cellular activity in many, if not all, cyanobacteria. A model for circadian control has been proposed in cyanobacteria, called the oscilloid model, which is based on topological changes of nucleoid DNA which in turn regulate...
Major Conservation Policy Issues for Biodiversity in OceaniaNARA Subscribed
Oceania is a diverse region encompassing Australia, Melanesia, Micronesia, New Zealand, and Polynesia, and it contains six of the world's 39 hotspots of diversity. It has a poor record for extinctions, particularly for birds on islands and mammals. Major causes include habitat loss and degradation, invasive species, and overexploitation. We identified six major threatening processes (habitat loss and degradation, invasive spec...
Aim A hierarchical framework is presented for modelling the spatial distribution of terrestrial vertebrate animals. Location The location of the study is the montane ash forests of the Central Highlands of Victoria, south‐eastern Australia. Methods The framework is illustrated using as a case study the distribution of Leadbeater’s Possum [ Gymnobelideus leadbeateri McCoy, 1867, ( Marsupialia: Petauridae )], a small arboreal ma...
Aim This study identified the factors influencing the presence, stocking rate and basal area of the southern Australian cool temperate rain forest tree myrtle beech ( Nothofagus cunninghamii ). Location This investigation was conducted in the montane ash forests of the Central Highlands of Victoria, south‐eastern Australia. Methods The occurrence of N. cunninghamii was measured as part of field surveys of 474 sites (2844 plots...
