Looking forward to it, @Jofre Espigule-Pons!

Hi @Jay Morreale, the recording link was included in today's email reminder. The link is: https://www.gotostage.com/channel/daily-study-group

Hello , Can you please post the Notebook, you showed in regards to the "Tick" example. I want to try to correlate its population growth with weather such as rainfall... I am interested in the central WI area..

Thanks Andrew

Thanks very much, Andrew

You showed the histogram data, but during the class you increased the resolution for the month of May. I don' recall how you did that? Did you change "Month" to "Day" in the Histogram plot?

Thanks Andrew

Yes, if you change "Month" to "Day" you will get daily observations on DateHistogram.

Probably you are already aware of WeatherData function. You can use it to get rainfall info:

DateListPlot[
 WeatherData[
  Entity["AdministrativeDivision", {"Wisconsin", "UnitedStates"}][
   "Coordinates"], 
  "TotalPrecipitation", {{2018, 1, 1}, {2022, 12, 1}, "Month"}], 
 Joined -> True]

At the end of the Day 2 challenge example Jofre provided, the syntax trained["TrainedNet"][image] would not execute, but if I used c[image] it works as expected. Is there some code missing (i.e., I didn't see trained[] defined)?

Also, is there a shortcut for ResourceFunction["iNaturalistSearch"] that will create the iconized form on the fly like Ctrl + Enter for entities?

I'm trying to expand on the anole example, but apparently iNaturalistSearch is limited to a maximum of 200 observations, even though 3046 observations for the brown anole were counted for Houston. I'm unable to use the Page and MaxItems options to automate the extraction (although I can brute force it by manually extracting 200 observations at a time into separate variables and then using Join. I also tried to extract 3 different species using the Or ("|") operator, but that did not work. My goal is to visually show the displacement of the green anole by the brown anole over the last 20 years in Houston.

In Jofre's stink bug example, he used a SemanticImport of a *.csv file, but I'm not sure of its source.

In my meandering around the web, I became aware of another invasive lizard that's beginning to get noticed in Texas, the Argentine tegus - they're the size of a dog and grow to about 4 feet long. Oh, and BTW, they're voracious omnivores!

I was finally able to create animations similar to that in Jofre's stink bug example for the brown and green anole. Both animations are based on GBIF data. When the distributions are compared for a given year, it appears both populations are increasing and that green anoles are apparently not being displaced by the brown anoles. What's being depicted, however, is probably the increasing frequency of observations being reported, rather than any change in the true populations of these two species year-by-year. I can report, however, that I have not seen any green anoles around my house or on my walks this year. Perhaps because I'm not looking in the right places; e.g., the brown anoles have taken over the ground and the green anoles have moved into other niches, such as tree canopies or less urbanized areas like parks.

Nice animations! You are right, for a comparative analysis one would need to take into account the rise in number of observers over the last years. Or maybe you could plot their relative abundance over time for these two species. In this article they also point out the change in habitat for the green anole as you mentioned: https://www.anoleannals.org/2015/06/10/are-brown-anoles-in-florida-really-driving-green-anoles-to-extinction/

Hi @Juergen Kanz , there was presentation on this particular topic at the Wolfram Tech Conference 2020, that you might want to watch. https://www.wolfram.com/broadcast/video.php?c=488&p=3&v=3252

It isn't an easy task yet. Probably, the most laborious task will be to manually tag the labels and add bounding boxes on your training dataset. Hopefully in the near future there will be more tools for automating this task.

Hi Jofre,

Yes, this presentation is going into the right direction. Is it possible to get access to the notebook?

Thanks in advance.
