From Birdsong Metrics to Ancient Arctic DNA: Selected Publications from the 1st Quarter, 2014
In the first quarter of 2014, researchers at The Environment Institute have published on a vast array of topics, from Ancient DNA in the Arctic, to birdsongs to recommendations for improvements to guidelines such as the Ecological Footprint in order to better inform policy makers.
A selection of these publications is listed below.
Research into the type of vegetation present during the last 50 thousand years in the Arctic is presented. Rather than using fossilised pollen as the main source of data as has been the case for previous studies, this study used plant and nematode DNA from sites across the Arctic. This data brings into question the diet of megafauna such as the woolly mammoth.
An investigation into soil microfauna composition, abundance, and distribution in East Antarctica. The study found that where a population exists is likely to be determined by soil geochemistry.
Data from populations of Eucalyptus gracilis (white mallee or yorrell) across the Murray-Darling Basin in southern Australia was collected in order to gain an understanding of how local environments affect seed quality.
The effect of deforestation and climate change on bird communities in Lore Lindu National Park, Sulawesi, Indonesia was investigated. The National Park is a globally important hotspot of avian endemism, and has lost almost 12% of its forest in the decade of 2000-2010.
This article seeks to demonstrate that 鈥淓cological Footprint鈥 measurements as currently constructed and presented misleading and cannot be used effectively in any serious science or policy context. Outlined are a set of principles that any ecological indicator should be based on in order to be scientifically sound and relevant for use in decision making.
It is suggested that care in interpretation of mean trophic level (MTL) of catches should be taken because reductions do not necessarily reflect change in species high on the food chain by fishing pressure. They found that the change in MTL is mainly attributable to large catches of sardines.
A convention of ecological nomenclature as well as a transnational institution to manage it is proposed, in order to overcome the synonymy and polysemy across disciplines, which currently handicaps the progress of ecology.
Three principles that underpin alternative water source choices are introduced: Reliability, thresholds and future projections of water quality and quantity.
The first large-scale evolutionary study of long noncoding RNA (lncRNA) repertoires and expression patterns in eleven tetrapod species is presented. About 400 highly conserved lncRNA鈥檚 (of more than 10 000 identified) probably originated an astonishing 300 million years ago at least.
The temperature and oxygenation of the oceans are influenced by one of the most fundamental biogeochemical processes on Earth-the burial of organic carbon in marine sediments. This buried organic carbon also comprises the primary source of hydrocarbons. This paper presents research into the composition of Woodford Shale.
A reference guide to the diverse seagrasses present in the ocean of the temperate parts of the southern hemisphere. Evolution, biology and ecology of the seagrasses is introduced. This book allows readers to rapidly identify a particular species, including those often confused with others.
Bird species such as the common nightingale and European blackbird have songs that are known to have inspired classical music. Developing a metric for these songs might help identify birds that are present in international bird trade which could contribute to studies of invasion and conservation biology.
A review of recent theoretical and empirical evidence concludes that the population rules for minimising inbreeding and for maintaining evolutionary potential in perpetuity need to be at least doubled and sections of the IUCN Red List criteria require revision, to be more effective conservation tools.
Did the Polynesians beat Columbus to South America? Not according to the tale of migration uncovered by analysis of ancient DNA from chicken bones recovered in archaeological digs across the Pacific. The ancient DNA has been used to study the origins and dispersal of ancestral Polynesian chickens, reconstructing the early migrations of people and the animals they carried with them. This study reveals that previous claims of contact between early Polynesians and South America were probably based on contaminated results. Instead, the new study has identified and traced a unique genetic marker of the original Polynesian chickens that is only present in the Pacific and Island Southeast Asia.
