Abstract

Abstracts are not currently available in GtR for all funded research. This is normally because the abstract was not required at the time of proposal submission, but may be because it included sensitive information such as personal details.

Planned Impact

The nature of the research topic means that much of the direct benefit will be for the academic community (see Academic Beneficiaries), however as it tackles the emergence of complex life on Earth there will be significant public interest in the research topic, approach, progress and outputs. Going beyond the topic itself, our approach is non-traditional in that it is highly integrative and seeks to develop and exploit a step change to develop inter-operable multi-parameter datasets and models, impacting how others research similar 'Earth System' topics.

Beyond the academic community (see Academic Beneficiaries) we expect the general public, in UK and China, will be beneficiaries of the research. The 'Cambrian explosion' and the origin of complex life on our planet was listed in an Economist article 'Life, the multiverse and everything, Science has remade the world, but scientists are not finished yet' (6th August 2015) as one of Science's six unsolved mysteries. This highlights that the research topic covered by this proposal is one of the big ones that captures the public's interest. We will develop novel web, using Quick Response (QR) codes and MediaWIKI infrastructure to communicate project science at sites where the rocks outcrop, and museums. We expect this to generate interest in the Earth and Biological Sciences, highlighting how the Earth system has evolved and operated prior to becoming our familiar world, will allow us to engage with the public and get them to think about complexity, feedbacks, and how systems evolve. Whilst the current changes facing the planet are operating at different timescales there are parallels to be made and lessons to be learnt from studying the 'Cambrian explosion'.

The focus on 'data mining and management' within this project allows us to identify those organisations and professional scientific bodies who are invested in developing geoscience 'data management' tools. In the case of this project, such organisations would include the International Commission on Stratigraphy (ICS), the Interdisciplinary Earth Data Alliance (IEDA), and the EARTHTIME Initiative. These organisations will benefit from our engagement with such systems and using this project to accelerate development in identified key areas. These will include aiding the federation of data from the GEOCHRON databased with the stratigraphic data in the GeoBiodiversity Database, and the development of 'age-model' tools within the later.

A third group of beneficiaries represent the industries that are engaged with exploring the resource potential of late Precambrian and earliest Phanerozoic sedimentary successions. The resources in question are primarily hydrocarbons although economic sulphide and phosphorite deposits occur within these successions. With respect to hydrocarbons the late Precambrian is considered a frontier for exploration, and significant accumulations of Precambrian occur in basins such as the South Oman Salt Basin. The primary research we will generate will include information about the geochemistry of specific successions of the South China Platform, information about their palaeogeographic history and information about basin development. Companies and industry funded research consortia will benefit from the approach developed in this research programme. Furthermore, the data generated, placed within the developing global 4D framework will allow us to export information to other basins which may have an economic potential (e.g., Oman, Brazil).

Title Data from: Evolution of fungal phenotypic disparity 
Description Organismal grade multicellularity has been achieved only in animals, plants, and fungi. All three kingdoms manifest phenotypically disparate body plans, but their evolution has only been considered in detail for animals. Here we seek to test the general relevance of hypotheses on the evolution of animal body plans by characterising the evolution of fungal phenotypic variety (disparity). The distribution of living fungal form is defined by four distinct morphotypes: flagellated, zygomycetous, sac-bearing, and club-bearing. The discontinuity between morphotypes is a consequence of the extinction of phylogenetic intermediates, indicating that a complete record of fungal disparity would present a much more homogeneous distribution of form. Fungal phenotypic variety gradually expands through time for the most part but sharply increases with the emergence of multicellular body plans. Simulations show these temporal trends to be decidedly non-random, and at least partially shaped by hierarchical contingency. Fungal phenotypic distance is decoupled from changes in gene number, genome size, and taxonomic diversity. Only differences in organismal complexity, the number of traits that constitute an organism, at the cellular and multicellular levels present a meaningful relationship with fungal disparity. Both animals and fungi exhibit a gradual increase in disparity through time, resulting in distributions of form made discontinuous by the extinction of phylogenetic intermediates. These congruences hint at a common mode of multicellular body plan evolution.
