What's On at UWA

Title: Simple bodies of calcaronean sponges are products of complex developmental toolkits

Abstract: Evolution of animal body plans, and genomic changes that are underlying the morphological changes, are key biological problems. From cnidarians to humans, bodies are patterned by a (...)

How does a Venus flytrap know when to snap shut? How do flowers know when to show their pretty colours? Can plants actually hear the chatter of the neighbourhood? This seminar is a window open onto the realm of plants, one hour detour into the history of how we perceive them, what we know about (...)

Title: The Australian Coastal Ocean Radar Network facility of IMOS – present and future.

Abstract: HF ocean radars provide maps of surface currents over meso-scale areas of coastal ocean and make it possible to map real-time dynamics of sea surface currents across substantial areas of (...)

Prof Charitha Pattiaratchi (UWA) WAIMOS Infrastructure in the Kimberley

West Australian Integrated Marine Observation System (WAIMOS) is a node of the Integrated Marine Observation System (IMOS) and with recent co-investment from the WA State Government, extended its deployment of (...)

Identifying structure in aquatic environments and showing the relationship to phytoplankton diversity is challenging because it is difficult to make direct measurements of all relevant variables at the necessary temporal and spatial scales. Two new approaches are demonstrated, which allow (...)

Title: Can Law Protect Sharks? Enhancing legal frameworks for the conservation and management of sharks

Abstract: Sharks are threatened by a range of activities including fishing and tourism as well as environmental impacts such as habitat loss and pollution. Addressing these challenges (...)

Extreme rainfall over the south and north-west of Western Australia and the Sydney region of NSW over the last fifty years has been modelled using a Bayesian hierarchical approach based on statistical extreme value theory. Spatial variability of the extreme rainfall distribution is modelled using a (...)

Title: Coral-dinoflagellate symbiosis: evolution, ecology and interaction states

Abstract: Corals form an obligate symbiosis with unicellular photosynthetic dinoflagellates. The diversity of dinoflagellates associated with a host is the result of both evolutionary and ecological (...)

Physical processes in lakes are the result of a large number of different mechanisms occurring over a wide range of temporal and spatial scales affecting ecosystem function in a variety of ways. Hence, a deep understanding of the lake hydrodynamics and its variability is essential in understanding (...)

Beach morphology is the result of complex interactions between sand transport, mean sea level, wind, surface gravity waves, and currents, all of which act over a range of temporal and spatial scales. Interactions with rocky landforms add another level of complexity to the mechanisms of beach (...)

A public lecture by Dr Scott Draper, Centre of Offshore Foundation Systems and UWA Oceans Institute.

Western Australia is bordered by substantial resources of marine energy - waves generated from storms in the Southern and Indian Oceans provide significant energy flux to the South of the (...)

Title: Perth Wave Energy Project – An Example of Multidisciplinary Ocean Engineering

Abstract: Carnegie’s first grid-connected CETO wave energy project is to be located at Garden Island in Western Australia as a result of the recent award of a $9.9m Federal Government grant from (...)

Macroecological theory predicts that along direct physiological gradients there will be unimodal abundance distributions of species and consistent rates of assemblage turnover. However, the majority of marine studies that have investigated the realised distribution of species along latitudinal or (...)

Throughout the globe, beaches are underlain and fronted seaward by rock and coral landforms. In Western Australia, many of our beaches are perched on coral, limestone and granite reefs and platforms. These hardlandforms have a strong influence on cross-shore and longshore sediment transport (...)

The Great Barrier Reef is a valuable natural asset that provides $6 billion per annum to the Australian economy and supports more than 50,000 jobs, primarily in tourism. It’s an irreplaceable resource, a national and international icon, and it is slowly declining. In the past 50years more than (...)

Title: Anchovy collapse in the Bay of Biscay: to eat or not to eat

Abstract: Anchovy (Engraulis enchrasicolus) is one of the main resources of the Basquepurse seiner fleet in the Bay of Biscay, as well as a cultural item for thesociety. A succession of recruitment failures starting in (...)

Lakes are now considered as significant greenhouse gas (GHG) conduits to the atmosphere. Small and shallow aquatic systems in particular such as ponds and wetlands can represent large GHG emitters as they generally contain high nutrients and organic carbon and have a small volume to area ratio (...)

South-western Australia was a part of Gondwanaland, and some of the most ancient parts of the Earth’ crust can be found here. Other parts of the landscape originated more recently from calcareous marine deposits [1]. Therefore, the soils of Western Australia are amongst the most heavily leached (...)

The Western Australian Integrated Marine Observing System - Annual Science Meeting will present the collaborative and cross-disciplinary uptake of freely accessible coastal and open ocean datastreams. Marine scientists, modellers and engineers, oceanographers and biologists will find this meeting (...)
