SLA is highest in the Temperate midlatitudes from where it decreases towards the poles, towards the interiors of the contents and towards the subtropics and tropics (based on sPlot 1.0 and a fully gap-filled version of TRY 2.0).

Hinweis der Redaktion
- Australian is now Advanced - Not limited to Australia or even ecology
- The steps in self-service data publication involve researchers making deposits online to a repository and these are accessible via an online data portal. Data publication for organisations is more technical due to the volume of data, its structure and complexity. A data analyst is at the coal face assisting data managers to deposit their data so that it’s integrated and comparable across different research topics and methods. In response to researchers wanting greater data access efficiencies and iconic research profiles, more portals I predict will shift to integrated site data in the future. So that’s what’s broadly involved but let’s look at TERN’s SHaRED as an example to see the broad steps in data publishing.
- Key message: We built the Australian Ecological Knowledge and Observation System to support the urgent needs of the ecological science community. Two core products, one developing and 2 core e-services.
- Niche: Primary, complex, well-described, integrated, ecological survey data – the baseline data fundamental to ecologists undertaking their profession to create new science, knowledge, policy and management of Australia’s nature and enviroments.
- Lots of pubs discussing the challenges and benefits of data publication and sharing
- Key Points: Data is dispersed meaning that discovery involves having to in search multiple places Because there are multiple custodians, multiple approaches to owners are needed and there is often ambiguity around licensing and conditions of use Data is complex meaning that it needs explanation and context to be understood. Nevertheless, data is often poorly described making it hard to interpret – leading to the possibility of inappropriate use Ecological data is diverse and fragmented meaning it covers a broad range of topics. Things can be observed and measured in different ways using different models There are however a lack of standards for methods around the way data is stored and represented
- Key Points: Aekos literally makes new research possible both by exposing data that was previously inaccessible, and also by lowering the barriers to reuse by condensing literally months work down to days by focussing on streamlining many of the more time consuming parts of the process AEKOS has a number of unique features like extensive contextual information aimed at giving the user a good level of understanding of the nuances of the data and the ability to search the actual data at a site level AEKOS also integrates the data where possible saving the user a lot of time trying to massage the data into a consistent format for analysis Many online systems allow searching for data and some allow direct access BUT AEKOS does this in a way that is optimized for the target user community – which we determined by soliciting community feedback
- Need to think of information as comprising several components Data will always be important but we need to improve management of supporting details
- Accessed via pickers currently Can’t us query languages as our users cant speak them…
- Initial result summaries help user determine which records are likely to be useful Important if you have a lot of results to review
- Exploring the data to help determine appropriateness Understanding the goals of the project, methods used, sampling design etc Conditions of use
- Because there is so much variation in method, need to provided detailed information on what was done Shows detailed method info divided under standard headings Info on any classification systems used, measurement standards + Diagrams etc to aid understanding The idea is that enough info should be conveyed for a new researcher to go out and confidently reproduce the method in the field
- ÆKOS applies a flexible Knowledge Representation approach to dealing with observation data. We consider our problem as publishing a set of books discussing overlapping topics, written by different authors in different languages: Our job is to translate a set of disparate books into a common language and style to make a “monographic series”.
- For those that want to get into the actual data The system has a rather unique way of representing data as models of reality rather than tables with rows and columns of numbers Because different surveys observe and measure different aspect of the environment, this approach allows the graph layout to represent any sampling configuration and can be extended to easily incorporate new attributes as necessary
- Integration is carried through to download
- Key message: ÆKOS spatial coverage is extensive although there are obvious gaps in the NT, WA, Victoria and Tasmania. Tasmanian holdings will improve at the end of the month with a platypus dataset. Victorian fire data and NT vegetation database which are promised will fill some gaps.
- Key message: ÆKOS offers the full richness of ecological data to meets user demands for ‘researcher standard’ data. Equally ALA and ANDS offer less complexity because the public aren’t seeking research details and ANDS is a cataloguer of all data repositories in Australia – totally different purpose to other platforms.
- Key message: ALA, other Atlases and ÆKOS are leaders in integrated data. The difference is ÆKOS supplies ‘research standard’ site data – the traditional unit of collecting ecological data. ALA supplies integrated species data ALA which is excellent for assessing species list, species distributions and taxonomies ÆKOS provides offers well-described ecological ‘plot’ data to support researcher needs. ALA provides minimal description as there focus is species atlas data to meet citizen science needs.
- Key points: Thanks sponsors.
