Although stem rust is mostly controlled by means of resistance cultivars, leaf and stripe rust continue to be major problems in many wheat-growing areas of the world. This book provides a basis to identify genes for resistance to stem, leaf and stripe rusts of wheat. Typical phenotypes associated with most known genes for resistance to the three rust diseases of wheat are illustrated in full colour. The book aims to assist the plant breeder to identify candidate resistance genes, thereby saving substantial time and resources before a single cross is made for genetic analysis.

Mayflies are one of the world's most diverse, abundant and important aquatic insects. Famous for their brief adult life spans, mayflies play a key role in the ecology of aquatic and associated terrestrial ecosystems, and are critical bioindicators of ecosystem health. Sitting at the southern limit of Australia's temperate zone, Tasmania is home to a diverse array of mayflies and renowned fisheries based on them. The state's storied "Lambda Dun" hatches bring fishers from all over Australia to try their luck each summer on its rivers and ponds. Yet little is known about their behavior and ecology, and more than half of the mayflies in Tasmania have never been described. This extensively illustrated book is the first synthesis of the biology of south-east Australia's mayflies, with a focus on those in Tasmania. It combines information gleaned from scientific literature as well as more than 30 years of the author's studies and flyfishing experiences. It explores the biology, identification, conservation, ecology and behavior of mayflies, and also includes fishing strategies and fly patterns. Tasmanian Mayflies is an essential information source for Australia's aquatic biologists and for flyfishers, novice and experienced alike, who chase the insects and the fish that feed on them. Features: Comprehensive coverage of Tasmania's diverse mayflies, with information on related species on the south-eastern mainland.Detailed information on life history, behavior and ecology based on over 30 years of studying mayflies.Includes diagnostic features for all major groups and species.Extensively illustrated with color photographs.Provides details on hatches, fly patterns and fishing strategies for flyfishers.

Until the mid-20th century, the thylacine was the world's largest carnivorous marsupial, and its disappearance has left many questions and contradictions. Alternately portrayed as a scrouge and as a high value commodity, the thylacine's ecology and behaviour were known only anecdotally. In recent years, its taxonomic position, ecology, behaviour and body size have all been re-examined scientifically, while advances in genetics have presented the potential for de-extinction. With 78 contributors, Thylacine: The History, Ecology and Loss of the Tasmanian Tiger presents an evidence-based profile of the thylacine, examining its ecology, evolution, encounters with humans, persecution, assumed extinction and its appearance in fiction. The final chapters explore the future for this iconic species - a symbol of extinction but also hope.
For most of the past 300 million years, the world's continents were interlinked as the supercontinents Pangaea and then Gondwana. Around 50 million years ago, Australia tore itself free from Antarctica to become the huge, splendidly isolated island it is today. Over time, its creatures began to evolve in ways not seen anywhere else on Earth, with tree-climbing crocodiles, gigantic venomous lizards, walking omnivorous bats and flesh-eating kangaroos roaming the continent.Prehistoric Australasia: Visions of Evolution and Extinction presents some of the most extraordinary creatures the world has ever seen - all unique to Australia, New Guinea, New Zealand and their surrounding islands.Over 100 meticulously painted panoramas by palaeoartist Peter Schouten are accompanied by descriptions of the unique environments and features of these animals, written by four of Australia's foremost palaeontologists. This book explores the nature and timing of extinction events in the Southern Hemisphere, considers whether some of these losses might be able to be reversed, and how we can use the fossil record to help save today's critically endangered species. Through stunning artwork and fascinating text, Prehistoric Australasia brings this globally unique transformation over time to glorious, colourful life.
The Australian wildfires of 2019-20 (Black Summer) were devastating and unprecedented. These megafires burnt more than 10 million hectares, mostly of forests in southern and eastern Australia. Many of the fires were uncontrollable. These megafires affected many of Australia's most important conservation areas and severely impacted threatened species and ecological communities. They were a consequence of climate change - and offered a glimpse of how this is likely to continue to affect our future. "Australia's Megafires" includes contributions by more than 200 researchers and managers with direct involvement in the management and conservation of the biodiversity affected by the Black Summer wildfires. It provides a comprehensive review of the impacts of these fires on all components of biodiversity, and on Indigenous cultural values. These fires also triggered an extraordinary and highly collaborative response by governments, NGOs, Indigenous groups, scientists, landholders and others, seeking to recover the fire-affected species and environments - to restore Country. This book documents that response. It draws lessons that should be heeded to sustain that recovery and to be better prepared for the inevitable future comparable catastrophes. Such lessons are of global relevance, for wildfires increasingly threaten biodiversity and livelihoods across the globe.

Wildland fires have an irreplaceable role in sustaining many of our forests, shrublands and grasslands. They can be used as controlled burns or occur as free-burning wildfires, and can sometimes be dangerous and destructive to fauna, human communities and natural resources. Through scientific understanding of their behaviour, we can develop the tools to reliably use and manage fires across landscapes in ways that are compatible with the constraints of modern society while benefiting the ecosystems.The science of wildland fire is incomplete, however. Even the simplest fire behaviours - how fast they spread, how long they burn and how large they get - arise from a dynamical system of physical processes interacting in unexplored ways with heterogeneous biological, ecological and meteorological factors across many scales of time and space. The physics of heat transfer, combustion and ignition, for example, operate in all fires at millimetre and millisecond scales but wildfires can become conflagrations that burn for months and exceed millions of hectares.Wildland Fire Behaviour: Dynamics, Principles and Processes examines what is known and unknown about wildfire behaviours. The authors introduce fire as a dynamical system along with traditional steady-state concepts. They then break down the system into its primary physical components, describe how they depend upon environmental factors, and explore system dynamics by constructing and exercising a nonlinear model. The limits of modelling and knowledge are discussed throughout but emphasised by review of large fire behaviours. Advancing knowledge of fire behaviours will require a multidisciplinary approach and rely on quality measurements from experimental research, as covered in the final chapters.
Australia is home to an incredible diversity of native animals. While Australian animals are among the most unique in the world, they are also among the most endangered, with hundreds currently on the brink of extinction. We must act quickly if we are to save these species, as once gone, they are gone forever.Extinct is a collection of artworks from established and emerging Australian fine artists, each depicting an Australian animal that has already, for various reasons, tumbled over the edge into extinction. Extinct laments their loss, but also celebrates their former existence, diversity and significance. The stunning artworks are accompanied by stories of each animal, highlighting the importance of what we have lost, so that we appreciate what we have not lost yet.Extinct features artworks from Sue Anderson, Brook Garru Andrew, Andrew Baines, Elizabeth Banfield, Sally Bourke, Jacob Boylan, Nadine Christensen, Simon Collins, Lottie Consalvo, Henry Curchod, Sarah Faulkner, Dianne Fogwell, David Frazer, Martin George, Bruce Goold, Eliza Gosse, Simone Griffin, Johanna Hildebrandt, Miles Howard-Wilks, Nick Howson, Brendan Huntley, Ben Jones, Alex Latham, Rosemary Lee, Amanda Marburg, Chris Mason, Terry Matassoni, Rick Matear, Eden Menta, Reg Mombassa, Tom O'Hern, Bernard Ollis, Emma Phillips, Nick Pont, Geoffrey Ricardo, Sally Robinson, Anthony Romagnano, Gwen Scott, Marina Strocchi, Jenny Watson and Allie Webb.
