Available in PDF, EPUB and Kindle. Book excerpt: Australian Saltmarsh Ecology presents the first comprehensive review of the ecology and management of Australian saltmarshes. The past 10 years in particular have seen a sustained research effort into this previously poorly understood and neglected resource. Leading experts in the field outline what is known of the biogeography and geomorphology of Australian saltmarshes, their fish and invertebrate ecology, the use of Australian saltmarshes by birds and insectivorous bats, and the particular challenges of management, including the control of mosquito pests, and the issue of sea-level rise. They provide a powerful argument that coastal saltmarsh is a unique and critical habitat vulnerable to the combined impacts of coastal development and sea-level rise. The book will be an important reference for saltmarsh researchers, marine and aquatic biologists, natural resource managers, environmentalists and ecologists, as well as undergraduate students and the interested layperson.

This book was released on 2016 with total page 37 pages. Available in PDF, EPUB and Kindle. Book excerpt: Oysters provide vital ecosystem services for coastal ecosystems worldwide. Sydney rock oysters (Saccostrea glomerata) are among the most important native Australian oysters. In 1990, a selective breeding program for faster growth rates was implemented for S. glomerata. This has since expanded to include breeding for resistance to winter mortality and QX disease. Selectively-bred oysters are currently farmed in estuaries containing wild oyster populations, providing the opportunity for interbreeding that could alter the genetic variability and structure of the wild populations. Here, we use next-generation genotype by-sequencing to investigate the genetic structures of wild populations and the selectively bred B2 line of S. glomerata. These data are used to test for genetic introgression between the populations at two sites in the Georges River, an estuary in Sydney where selectively bred oysters have been farmed since 1990. Strong genetic partitioning was identified between wild and selectively-bred populations and there was no evidence of sustained gene flow in the form of introgression. Contrary to our expectations, we found significantly higher levels of genetic diversity and heterozygosity in the selectively-bred population than the wild population. These results potentially reflect the impact of population bottlenecks and are relevant to the resilience of this species to environmental change.

Book excerpt: Throughout the Earth's history climate change has led to a proliferation and disappearance of species thus playing a major role in shaping the structure of marine ecosystems. Over the next century, rising atmospheric carbon dioxide (CO2) levels will cause a rise in the partial pressure of CO2 (pCO2) in the surface ocean leading to a reduction in surface ocean pH from 8.1 to 7.7 units and a reduction in the concentration of surface ocean carbonate ions (in a process known as 'ocean acidification') vital in the construction of calcium carbonate (CaCO3) shells and skeletons. At the same time, this rise in atmospheric CO2 levels will lead to an increase in sea-surface temperatures (SSTs). Of growing concern are the potentially serious implications that ocean acidification and rising SSTs may have on marine organisms and ecosystems and the potential risk to marine aquaculture internationally. Recent studies, which have mimicked ocean acidification, have reported adverse consequences of elevated pCO2, including reduced calcification and growth, and increased rates of abnormality and mortality in larvae and adults of a range of marine organisms. Yet, we know comparatively little of the synergistic consequences of elevated pCO2 and temperature nor the potential for species to acclimate through genetic adaptation, at the population and ecosystem level. This lack of knowledge limits our ability to create models that accurately predict the consequences of future climate change. Among the organisms most likely to be affected in an acidifying and warming ocean are marine calcifying organisms which construct shells and skeletons of CaCO3. Studies on these organisms, to date, have focused predominately on adults, with comparatively few considering the sensitive early life history stages. This study compared the synergistic effects of elevated pCO2 and temperature on the early life history stages of two ecologically and economically important oysters: the Sydney rock oyster, Saccostrea glomerata and the Pacific oyster, Crassostrea gigas. Gametes, embryos, larvae and spat were exposed to four pCO2 (375, 600, 750, 1000 ppm) and four temperature (18, 22, 26, 30 °C) levels in acute exposure experiments. At elevated pCO2 and suboptimal temperatures there was a reduction in the fertilisation success of gametes, a reduction in the development of embryos and size of larvae and spat and an increase in abnormal morphology of larvae. These effects varied between species with S. glomerata having greater sensitivity than C. gigas. Combined, elevations in pCO2 of 750-1000 ppm and a temperature of 30 °C resulted in 100% mortality of D-veliger larvae of S. glomerata. In contrast, the same pCO2 and temperature combination resulted in only 26% mortality of D-veliger larvae of C. gigas. A comparison between two commonly used methods for manipulating the seawater carbonate system (HCl-acidification and CO2-acidification) showed that there was no significant difference in the responses of S. glomerata and C. gigas to the two methods. This indicates that both HCl-acidification and CO2-acidification are adequate methods for determining the effects of elevated pCO2 for these species.
