Guidelines For Model Adaptation: A Study Of The Transferability Of A General Seagrass Ecosystem Dynamic Bayesian Networks Model, Paula Sobenko Hatum, Kathryn Mcmahon, Kerrie Mengersen, Paul Pao Yen Wu
Guidelines For Model Adaptation: A Study Of The Transferability Of A General Seagrass Ecosystem Dynamic Bayesian Networks Model, Paula Sobenko Hatum, Kathryn Mcmahon, Kerrie Mengersen, Paul Pao Yen Wu
Research outputs 2022 to 2026
In general, it is not feasible to collect enough empirical data to capture the entire range of processes that define a complex system, either intrinsically or when viewing the system from a different geographical or temporal perspective. In this context, an alternative approach is to consider model transferability, which is the act of translating a model built for one environment to another less well-known situation. Model transferability and adaptability may be extremely beneficial—approaches that aid in the reuse and adaption of models, particularly for sites with limited data, would benefit from widespread model uptake. Besides the reduced effort required to …
Habitat Selection By Vulnerable Golden Bandicoots In The Arid Zone, Cheryl A. Lohr, Kristen Nilsson, Colleen Sims, Judy Dunlop, Michael T. Lohr
Habitat Selection By Vulnerable Golden Bandicoots In The Arid Zone, Cheryl A. Lohr, Kristen Nilsson, Colleen Sims, Judy Dunlop, Michael T. Lohr
Research outputs 2014 to 2021
In 2010, vulnerable golden bandicoots (Isoodon auratus) were translocated from Barrow Island, Western Australia, to a mainland predator-free enclosure on the Matuwa Indigenous Protected Area. Golden bandicoots were once widespread throughout a variety of arid and semiarid habitats of central and northern Australia. Like many small-to-medium-sized marsupials, the species has severely declined since colonization and has been reduced to only four remnant natural populations. Between 2010 and 2020, the reintroduced population of golden bandicoots on Matuwa was monitored via capture–mark–recapture data collection, which was used in spatially explicit capture–recapture analysis to monitor their abundance over time. In 2014, we used …
Seasonal Variation Of Bacterial Diversity Along The Marine Particulate Matter Continuum, Mireia Mestre, Juan Höfer, M. Montserrat Sala, Josep M. Gasol
Seasonal Variation Of Bacterial Diversity Along The Marine Particulate Matter Continuum, Mireia Mestre, Juan Höfer, M. Montserrat Sala, Josep M. Gasol
Research outputs 2014 to 2021
© Copyright © 2020 Mestre, Höfer, Sala and Gasol. Seasonal dynamics of ocean prokaryotic communities in the free-living fraction have been widely described, but less is known about the seasonality of prokaryotes inhabiting marine particles. We describe the seasonality of bacterial communities in the particulate matter continuum by sampling monthly over two years in a temperate oligotrophic coastal ecosystem and using a serial filtration (including six size-fractions spanning from 0.2 to 200 μm). We observed that bacterial communities in the particulate matter continuum had annual changes following harmonic seasonal oscillations, where alpha, beta, and gamma diversity increased during the warm …
Trophic Roles Of Tadpoles In Tropical Australian Streams, Katrin Schmidt, Melanie L. Blanchette, Richard G. Pearson, Ross A. Alford, Aaron M. Davis
Trophic Roles Of Tadpoles In Tropical Australian Streams, Katrin Schmidt, Melanie L. Blanchette, Richard G. Pearson, Ross A. Alford, Aaron M. Davis
Research outputs 2014 to 2021
Tadpoles can be abundant consumers in stream ecosystems, and may influence the structure and function of streams through their feeding activities and interactions with other organisms. To understand the contribution of tadpoles to stream functioning, and the potential impact of their loss, it is necessary to determine their diets and how they might influence food-web structure. Using gut-content analysis and stable-isotope analysis of N and C, we determined the main food sources and trophic positions of tadpoles of five native frog species, invertebrates, and fish in upland and lowland Australian Wet Tropics streams. Omnivory was prevalent among the tadpoles and …
Trophic Implications Of Light Reductions For Amphibolis Griffithii Seagrass Fauna, Adam Gartner
Trophic Implications Of Light Reductions For Amphibolis Griffithii Seagrass Fauna, Adam Gartner
Theses: Doctorates and Masters
The ongoing threat of seagrass loss from reduced light availability, coupled with our lack of knowledge of associated trophic responses has motivated this characterization of the flow-on effects of light reductions to Amphibolis griffithii seagrass fauna. Recently, field manipulations of varying light reductions, induced disturbances in a A. griffithii seagrass meadow that have been shown to effect potential food resources and the structural complexity of seagrass habitats for macroinvertebrates. This offered the opportunity to assess the flow-on effects to seagrass for fauna, a topic that has seldom been examined. This study investigated the effects of different light reduction intensity (high: …
The Role Of Farm Dams As Refugia For Aquatic Invertebrates In A Salinised Landscape, South Western Australia, Jean-Michel Benier
The Role Of Farm Dams As Refugia For Aquatic Invertebrates In A Salinised Landscape, South Western Australia, Jean-Michel Benier
Theses: Doctorates and Masters
In a salinised landscape farm dams may represent the last truly freshwater surface resource, and therefore provide refuge habitats for the biota of wetlands affected by increasing salinity. One wetland threatened by increased salinity in south-west Western Australia is Lake Toolibin. It is listed as a Wetland of International Importance under the Ramsar Convention in recognition of its high conservation value, and remediation actions to halt (and possibly reverse) further increases in salinity are being undertaken at this wetland. Farm dams act as aquatic refugia if they convey resistance and/or resilience to the biotic communities of a disturbed habitat. This …
Aspects Of The Taxonomy And Ecology Of The Ground Beetle (Coleoptera: Carabidae) Assemblage Of The Swan Coastal Plain : (With Particular Reference To Habitat Fragmentation And The Quindalup Dune System), Nadine A. Guthrie
Theses: Doctorates and Masters
Long term studies encompassing seasonal variation in abundance and species present, forming base-line phenological data, arc required to understand the responses of the carabid (Ground Beetle) fauna to major habitat changes. In addition, few habitats unaffected by human disturbance remain in Australia, and evaluation of these fauna in these areas is required before further habitat loss occurs. Generally an unknown group of terrestrial predatory invertebrates in Australia, carabids have been the subjects of few ecological studies in this country. This restricts the utility of the Carabidae in environmental or conservation assessment programs in Australia. A study was initiated to assess …
