The Atlas of Living Australia team have just released a new and improved version of the OzAtlas mobile device App, available for download onto Android phones and tablets from today.
This application will allow users to retrieve lists of species recorded within an area, and to view details of the species such as recorded distribution, scientific name, common names and images all from the ease of your mobile phone. It also allows users to submit species occurrence records with an image to the Atlas of Living Australia, and to view the latest images added to the Atlas.
Some new improvements to this version include:
It is also much more responsive than the current version.
The App is completely free and available right now at the google play store – click here to download
The new version is available only on Android phones and the iOS version remains unchanged however still contains the same features.
If you have an Android phone why not download the App today. Please note that this is a new version and not an update so users will need to reinstall if they already have a previous version on there phone.
Current users include: citizen scientists, academics/researchers, field ecologists and even school and university students. Share this blog with anyone who you think would like to know about this information.
While at the google play store have a look and see what other ‘Apps‘ the Atlas of Living Australia have on offer.
By Lee Belbin (Atlas of Living Australia) and Norm McKenzie (Department of Environment and Conservation, Western Australia)
Mangroves are a much maligned group of trees. Yes, most of the time they do not make for a comfortable human environment. In mangroves, you could be up to your neck in mud being bitten by clouds of sand flies and eyeing a 5m croc (who is eying you) in 48 degrees Celsius and 100% humidity. Maybe that’s why developers like to clear mangroves for resorts while miners like to bulldoze them to create ports. But, they are crèches for many fish species and a host to many other species, one of which was the target of our safari.
Our ‘Snark’ for this trip was the bat species Morphopterus loriae cobourgiana (Ml for short). Its common names include Little Northern Scurrying Bat and Little Scurrying Bat. This, as you may have gathered, Morphopterus is a mangrove bat. It is small (about 25cm wingspan and 7-9gms), somewhat acrobatic and insectivorous (it eats bugs, but nowhere near enough).
Why were we looking for Ml? Its Western Australian population depends on the mangroves and mangroves in this region of Australia are under consistent threat. Each little patch of mangrove that gets cleared is a little patch but it all adds up to significant loss of habitat over a human lifetime. Mining companies operating in the Pilbara can provide funding that may help to conserve species such as Ml whose habitats are under threat.
Ml can be found in mangroves from Exmouth Gulf to King Sound in the northwest of Western Australia and near-coastal areas of the ‘Top End’ in the Northern Territory. We didn’t fly up to Exmouth and rent a 4WD, no. We drove from Perth to Exmouth Gulf via Carnarvon then on up to Derby. This is about 2600 kilometres, which is a ‘decent’ drive by Western Australian standards. The positive side of this craziness is that we get visit six different mangrove patches and to see a large number of ecosystems and landscapes on the way and some of the fauna and flora that they contain.
Norm McKenzie is a bat expert. What this means is that he dreams about bats and that any conversation will eventually involve bats. If you want to know about bats, Norm is your man. It’s grand that we have such people, but sad that most would only glean a little of his knowledge by wading through the usual scientific papers (see References).
Norm knows a lot about Ml, but if money was to be spent on conserving it, there were gaps in knowledge that needed to be filled. One of these gaps was to find out where Ml was in summer. As with any trip like this, you also try to address a few other issues, if you can.
I wanted to test out the Atlas of Living Australia’s mobile app called OzAtlas. This is an application for Apple and Android mobile devices for entering basic observations of species into the Atlas database.
To anyone interested in scenery and the things that it contains, this was a special trip – one that I (Lee Belbin) have wanted to do for nearly 20 years. If that wasn’t special enough, it was extra-special in that you don’t get to travel with one of Australia’s authorities not of only bats, but anything zoological in the western part of Australia.
We headed north from Perth on February 5th 2013 in the middle of the warmest, stickiest part of summer. The requisites for such a trip are in priority order:
A typical day involved finding the survey site and setting up equipment and ourselves for monitoring the bats over the evening. The sites were selected from previous survey sites that covered a fair extent of Ml’s range. Some of the sites had not been visited for many years so we needed time to find them again, setup the recorders and make visual observations. In one case, we spent two hours negotiating a track only suitable for serious 4-wheel drives, only to have to turn around and find another way in. Once we found the site, we then needed to identify a good location to setup the recorder.
The echo-location ability of bats is amazing. They generate sounds between 9,000 and 160,000 hertz (cycles per second) and use different sounds for different activities. They can navigate through complex environments and they can locate and capture moving prey. Each bat has a unique profile of the frequencies and pule structure that it uses for its activities. Each bat species also has a unique airframe, including wing body, tail and ear-canard shape.
The main recorder is carefully positioned in the mangroves to reduce reflected sounds and avoid being swamped by the incoming tide. We set it up, pray to the mangrove gods and come back in the morning hoping for 10 hours of clear recording. We also had a device that divides the bat echo-location sounds by 16, pulling for example sounds at 32,000 Hz to 2,000Hz allowing our far poorer hearing to listen in. This unit is also connected to a small, high quality digital voice recorder – a check on what is about while we are listening.
Once the main recorder is setup, we make camp and wait until about 6pm. We put on our long pants and shirt, tuck pants into socks, spread Aerogard or equivalent liberally on any exposed skin, pickup chair, head torches and binoculars and find a good observation possie. And wait, with the flies.
Sometimes a group of 30 or more bats rises up and heads off to forage. At other times, we sit and wait and see and hear nothing. This is all valuable data. If the sunset is nice, it’s a bonus. If the scenery is nice, likewise. If the stars are visible, ditto. If there is a light wind to blow away a percentage of flies and mosquitoes (without being too strong to blow away the bats – or more accurately, stop them from flying), wonderful. Good company also helps. If we see bats against the evening sky to the west, eureka. It’s a game of chance with the odds in our favour thanks to Norm’s knowledge.
Bats don’t like flying when their predators (falcons, kites, eagles etc) can see them, naturally enough. There is therefore a small window of time when we can see them and their predators probably won’t. Once it is dark, and there are bats about, we begin to hear the increasingly familiar tick, tick, tick…tickticktiktikitik of Ml or other species. This is a typical sound from an Ml. With expert advice, it is surprisingly easy to get your ear ‘in’ and identify the probable species. When we hear them, we can turn on the head torches and hopefully get a visual confirmation. Flight characteristics, size and colour complement the audio identification.
Most nights, we call it quits around 9pm. By that time, we have a fair indication of what species are around and their abundance. We had good nights, and one not so good night, but in the latter case, we got recordings of Ml on the electronics anyway.
We started the survey at the southern end of Exmouth Gulf on the mid-northwest coast and ended it at Derby in the northeast of Western Australia. In between, we surveyed mangrove stands at Onslow, Cape Keraudren, Derby and Point Torment (a fair indication of what to expect!). One night, we lost the main recorder to the waves. We estimated the tide from the marks on the shore but guessed wrong (see figure above). The tide was about 1m larger than expected due to the wind effect. The ‘waterproof’ box of electronics sadly wasn’t. It was an expensive lesson, but we still had our second recorder and our senses so all was not lost.
Our survey filled in the previous gaps in Ml’s distribution. In summer, we had low numbers in the south but high numbers in the north. In winter, greater numbers have been observed south of Cape Keraudren.
While waiting for darkness, we also identified any birds around the sites. Birds are one of the easiest of lifeforms to identify accurately, but like any species, there are always possible issues about names and features. The list of observed birds was then entered into the Atlas of Living Australia using OzAtlas. On our trip, this had to be done when we had some form of internet connection as OzAtlas currently uses the online Atlas database for species identification before adding in the new observations. A new version is being developed that will support offline recordings.
The Atlas of Living Australia requires five basic elements to form a valid observation record:
Many other aspects of an observation can be entered, but OzAtlas limits itself to the above. The app can also tell you what species occur within an area or show you images of species and their known spatial distribution. The usual process is to use OzAtlas to search for an observed species to check it against images and its spatial distribution. If you are confident, the observation is added directly to the Atlas. These records are subsequently checked using a range of data quality processes established by Atlas. If the observation is validated, it is available publicly.
Anyone can enter observations into the Atlas. We encourage it! Anything that helps us to know where species occur (on land or in water) – will help us to better understand the environment that supports all of us.
OzAtlas has been used by a wide range of people over the last year. This trip was a ‘use in anger’ exercise and didn’t disappoint. We found for example that:
The Atlas of Living Australia also has a far more advanced data entry application called FieldData for setting up forms for entering detailed species observations.
Reference collections in museums, herbaria, botanical gardens, zoos and other repositories are critical infrastructure for research, education, regulation and legislation related to biodiversity. These collections provide documentation of research results as well as long-term changes in nature. Patterns of ecological, evolutionary and anthropogenic changes often go unseen and undocumented until samples from these collections material are analyzed and re-analysed using the latest technology.
In order to be accessible and effective, reference collections need to be digitised and their data and metadata made available to the research and education community, to policy-makers, and to the general public. Digitisation in the most general sense is the association of an organism and its characteristics to a unique identifier that can be indexed for later searching and retrieval. It can take several forms, ranging from digital capture of label data (date and place of collection, taxonomic identification) to digital image capture and even DNA sequencing.
As part of the 12th Pacific Science Association Inter-Congress, being held from the 08 – 12 July 2013 at the The University of the South Pacific, Laucala Campus, Suva, FIJI, a full day session is being offered which will include a half-day symposium of contributed presentations on DNA barcoding and a half-day instructional workshop on biodiversity informatics. The DNA barcoding symposium will contribute toward development of a regional strategy for Oceania for construction and use of standardised barcode libraries. These libraries could serve basic research in ecology and evolution and/or applications such as the protection of endangered species and control of invasive alien species such as agricultural pests.
The biodiversity informatics workshop will showcase initiatives such as the Global Biodiversity Information Facility (GBIF), the Atlas of Living Australia (ALA), New Zealand Organisms register (NZOR), and digitization initiatives such as iDigBio and Australia’s Virtual Herbarium (AVH). This session will explore applications and network tools appropriate for the small and scattered countries and territories of Oceania. Participants will learn the latest approaches to the digitization of natural history collections and explore how these could be applied to their collections. The session will conclude with a round-table discussion on strategic development of, and support for, biodiversity informatics in the Oceania region.
The Secretariat of the Convention on Biological Diversity (CBD) has expressed its support for this proposed workshop as a contribution to enhancing capacity in taxonomy (a goal of CBD’s Global Taxonomy Initiative, GTI) and strengthening informatics infrastructure in the Pacific region. Academic collaborations on biodiversity facilitate achievement by CBD Parties in the region of Aichi Biodiversity Target 9 (invasive alien species) and Target 19 (Biodiversity science).

We would like to invite you to attend the Atlas of Living Australia Science Symposium to be held June 12-13 in Canberra. The Atlas has accomplished much over the past 5 years (see dashboard.ala.org.au). For example, we now have over 36 million records, nearly 500 environmental layers, images, sounds, video, and over 640 million records have been downloaded for use in over 20,000 separate events.
We will be holding a series of talks on achievements that were enabled through use of the Atlas infrastructure, and providing demonstrations and tutorials on the use of the Atlas.
Please set these dates aside so that you can join us – and pass this message on to any colleagues that you feel might be interested.
