  1. A lot. California has more biodiversity than the northeast US and Canada combined. Texas scores so high because they have a lot of rivers with endangered species. Deserts have a lot of biodiversity actually. Generally speaking, the closer you get to the equator the more biodiversity you have, and the zone where we get deserts is mostly between 30 and 50 degrees north and south.

  2. None. California has it's own law and a species that is protected under it is called "a species of special interest to the state of California." The Endangered Species Act is federal law. There is also an international organization called IUCN that designates species as endangered.

Temperature! See our figure from our paper and on wikipedia: https://en.wikipedia.org/wiki/Atmospheric_water_generator#/media/File:Least_work_AWH.png As seen, the energy needs is overlaid on a psychometric chart. The map itself is a yearly average, so it looks worse for regions that have dry seasons, even though AWH may be very easy in their wet seasons.. e.g. Look at Africa North and south of the Congo rainforest, or just South of the Amazon. Also, the map shows a strong influence of Hadley cells, with bands of low and high energy needs: https://en.wikipedia.org/wiki/Hadley_cell

Hi there! Thank you for the praise! Let me break down your questions:

  1. It is possible to generate these statistics and to figure out the biodiversity and proportion of endangered species sightings in comparison to the other species present. The two biggest issues are uncertainty of location and the size of the data in question. Because these animals are protected, some of the data is obscured to decrease the likelihood of poaching. This makes certain spatial analysis tricky and can lead to a decrease in accuracy. Second is that there are billions of sightings logged in GBIF and comparing these together even at smaller scales like a country or state become challenging. My lowly MacBook Pro and free GIS software simply doesn't have the bandwidth to conduct that level of analysis (although I really want to!). All of this to say, the solutions you've presented are possible!
  2. The way a species is defined as endangered for this map is controlled by an international agency. While different states and countries can create their own endangered species list, IUCN is the most internationally recognized. This eliminates bias on the local/state level but doesn't remove our charismatic animal-centric bias which is a big problem facing conservation.

Hopefully those answered your questions!

From an non-American perspective, sometimes I do think that the US is "invading" others in the name of "world peace". The middle-east is a great example. That's just my own thought tho. Not trying to start an argument as that would obviously be un-wise to do in an environment full of Americans

I'd be curious to know how many species there were to begin with and how many have already gone extinct.

Certain great plains states have basically one biome. Other states like California or Florida have a much more diverse set of biomes that can house a much larger variety of species.

It would be cool to see that represented too.
