Hi all,
I just arrived to Quest and hope we all are here or on the way. I see there is a bus from G Waverley at 9:23 tomorrow morning. Shall we meet at the stop of bus 737 there, at the station at about 9:15? I probably start walking form Quest at around 8:30, I understood that there is some shopping center with breakfast options on the way, I plan to have a quick bite there.
Note, that you need to have your Myki card ready before you go to the bus = before we meet at the bus stop. Because I am leaving on Sat, I just got a week long pass (39 AUD), but you might like to load money - I was told that single ride is 4 AUD, so load accordingly. I found it easier to get the card from Seven Eleven, from a human being.
Google suggest that there is a faster connection by 742 https://goo.gl/maps/95VJiic9wDz, but tomorrow on day 1, I will probably just follow the instructions.
I've a local SIM card, my number in AU is +61 (0) 415 253 830.
See you later today.
Dmitry
Hello group,
Here comes the information package for the Melbourne meeting, including information on logistics, check-in, agenda and tasks. Kindly check the attached carefully before you leave and feel free to be back to me if you have any questions.
Melodie adds that if anyone is uncertain about their tasks they should contact her, and if anyone wants to volunteer for some tasks that don't have leads please let her know, too.
Contact details of Melodie and Gillis are in the attached, those include mobile phone numbers for urgent contact situations. My contact details did not change and are repeated below.
Happy homework time and safe travels,
Best regards,

Hello group,
I have now closed the IAS survey, we've got 208 responses:
https://drive.google.com/drive/folders/0BzrSPi8wkHZ8cmRpLTNvOHRTVFE?usp=sha…
The summaries are found as PPT and as PDF. Individual responses in the Google table in the far right contain the valuable body of the free text comments. As agreed, in the secretariat we will compile of suggested IAS literature.
We will be sending arrival instructions and agenda documents shortly.
Thanks,
Dmitry
Hi Tim,
thanks that's all useful information. You confirmed what I suspected
regarding the dates of publication.
As I was working with the data I noticed several problems and biases that
confuse the results. A subset of 100 species is really too small to start
breaking down into different subsets. As you noted the over representation
of birds
Perhaps, the only take home message we should make at the moment is that
publishing of these data is not fast and that it would need to be improved
if GBIF were used for early warning.
I would not make any conclusions about the improvement in speed of
publication. This is an small and biased subset.
Regards
Quentin

I've had a look at the GBIF data for the 100 Worst Aliens. Just to remind
you, the intention is to see how long it takes for the records of invasive
species take to reach GBIF.
This first graph is a histogram showing the days between observation
(eventdate) and publication date (date_created) for each publication year.
What is notable is that there is no indication that the time to publication
is reducing with time. The GBIF analytics suggest that data are getting to
GBIF faster, but this is not clear from this subset (
http://www.gbif.org/analytics/global).
[image: Inline images 4]
Grouping all the observations together this histogram summarises the rate
of publication. Clearly, most observations take longer than a year to be
published.
[image: Inline images 2]
This is the same as above except for specimens. The numbers of records are
a lot less and I assume they take longer to get to GBIF as a result of the
the current digitisation of herbaria and museums.
