Wildlife Of The Gold Coast Wetlands, Shelley Burgin, Daryl Mcphee
Wildlife Of The Gold Coast Wetlands, Shelley Burgin, Daryl Mcphee
Daryl McPhee
Extract: Water in the landscape of the Gold Coast is dominated by marine and marine-influenced systems. The most obvious are the in-shore waters abutting the Gold Coast's world-famous beaches and estuaries. Little more than a glance at a map of the city also reveals the extensive canal estates built to take advantage of the marine waters, and indeed expand them. The waters of the rivers mix with the ocean's waters in the estuaries. These ecosystems are valuable nursery areas for marine wildlife, particularly, but not restricted to, fishes of commercial and recreational value.
Marine Environments Of The Gold Coast: Out With The Old, In With The New, Daryl Mcphee
Marine Environments Of The Gold Coast: Out With The Old, In With The New, Daryl Mcphee
Daryl McPhee
Extract: The marine environments of the Gold Coast comprise one of the most highly modified and heavily utilised waterways in Australia. Chapters 2 and 3 discussed changes in the historic land use patterns. Just what has this meant to the marine environments of the Gold Coast? In this chapter the contemporary marine h abitats of the Gold Coast are described, along with the fauna that those habitats support. We talk about how the current status of the habitats compares with various historical points in time, and the role of novel habitats. Given the impor tance of recreational fishing to both …
A Brief History Of Discovery, Settlement And Development, Tor Hundloe, Craig Page
A Brief History Of Discovery, Settlement And Development, Tor Hundloe, Craig Page
Tor Hundloe
Extract: If we can rely on anecdotal data, the answers to what is truly Australian will start with mention of the koala, go to kangaroos and then include the rest of Australia's peculiar (to foreigners) fauna. The only exception might be that if we asked a male from the Asian subcontinent (India, Pakistan, Sri Lanka and Bangladesh) what he identified Australia with, he might answer 'Cricket'. Putting that aside, the Gold Coast is very likely to be in the mix of Australian icons. To capture the essence of the Gold Coast, we need to talk about its history in more …
The Impact On The Gold Coast's Terrestrial Environments, Tor Hundloe
The Impact On The Gold Coast's Terrestrial Environments, Tor Hundloe
Tor Hundloe
Extract: We tend to think of the Gold Coast as a water environment. As tourists know, it sits on the shore of the vast Pacific Ocean. That is why most come. They have seen the magnificent photographs. If not perched on flattened dunes looking east to the ocean, a significant part of the urban Gold Coast environment is located around natural and human-made water environments. Of these we will say little here, other than to note their extent. The focus of this chapter is the city's terrestrial environments, reporting on and ultimately, after describing the environments, discussing what proportion of …
State Of The Environment, Tor Hundloe
State Of The Environment, Tor Hundloe
Tor Hundloe
Extract: What have we done? What have we learned? In this chapter we turn our attention to the people of the Gold Coast and their environmental impacts, as experienced in the 21st century. The past is gone. The damage is done. Dramatic change in landforms and ecological relationships are inevitable in building cities. From this we can only learn and do things better in the future. This is why there will never be another Gold Coast like the one we describe in this book.
Male-Biased Reproductive Effort In A Long-Lived Seabird., Robert Mauck, Jennifer Zangmeister, Jack Cercihara, Chalres Huntington, Mark Haussmann
Male-Biased Reproductive Effort In A Long-Lived Seabird., Robert Mauck, Jennifer Zangmeister, Jack Cercihara, Chalres Huntington, Mark Haussmann
Robert Mauck
Background: In dimorphic seabirds, the larger sex tends to provision more than the smaller sex. In contrast, monogamy and biparental care are often associated with equal effort between the sexes. However, the few studies that have tested sex-specific effort in monomorphic seabirds have primarily examined the details of foraging at sea. Hypotheses: Parental effort is also sex-biased in a monomorphic seabird mating system for one of two reasons: (1) If females enter the period of parental care less able to invest in care due to the cost of egg production, male-biased effort may be necessary to avoid reproductive failure. (2) …
Effects Of Temperature, Nutrients, Organic Matter And Coral Mucus On The Survival Of The Coral Pathogen, Serratia Marcescens, Erin Looney, Kathryn Sutherland, Erin Lipp
Effects Of Temperature, Nutrients, Organic Matter And Coral Mucus On The Survival Of The Coral Pathogen, Serratia Marcescens, Erin Looney, Kathryn Sutherland, Erin Lipp
Kathryn Patterson Sutherland PhD
Serratia marcescens is an enteric bacterium that causes white pox disease in elkhorn coral, Acropora palmata; however, it remains unclear if the pathogenic strain has adapted to seawater or if it requires a host or reservoir for survival. To begin to address this fundamental issue, the persistence of strain PDL100 was compared among seawater and coral mucus microcosms. Median survival time across all conditions ranged from a low of 15 h in natural seawater [with a first-order decay constant (k) = −0.173] at 30°C to a maximum of 120 h in glucose-amended A. palmata mucus (k = −0.029) at 30°C. …
Human Sewage Identified As Likely Source Of White Pox Disease Of The Threatened Caribbean Elkhorn Coral, Kathryn Sutherland, James Porter, Jeffrey Turner, Brian Thomas, Erin Looney, Trevor Luna, Meredith Meyers, J. Futch, Erin Lipp
Human Sewage Identified As Likely Source Of White Pox Disease Of The Threatened Caribbean Elkhorn Coral, Kathryn Sutherland, James Porter, Jeffrey Turner, Brian Thomas, Erin Looney, Trevor Luna, Meredith Meyers, J. Futch, Erin Lipp
Kathryn Patterson Sutherland PhD
Caribbean elkhorn coral, Acropora palmata, has been decimated in recent years, resulting in the listing of this species as threatened under the United States Endangered Species Act. A major contributing factor in the decline of this iconic species is white pox disease. In 2002, we identified the faecal enterobacterium, Serratia marcescens, as an etiological agent for white pox. During outbreaks in 2003 a unique strain of S. marcescens was identified in both human sewage and white pox lesions. This strain (PDR60) was also identified from corallivorious snails (Coralliophila abbreviata), reef water, and two non-acroporid coral species, Siderastrea siderea and Solenastrea …
