[Re:] Nearktis, Neotropis etc.

[Thomas Schlemmermeyer]

Dear Colleagues,

Before answering this biogeogrpahy-related question: Since yesterday,
I am trying to download the panbiogeography and ocean basin related article in
the september issue 1998 of the journal of biogeography on the home page of
this journal, but the archive seems to be corrupted.

If anyone has a functional version of this freely downloadable pdf-document
I would appreciate it very much, if he/she forwarded it to me....

The border between the neotropical region is generally put into Mexico.
In the mexican highlands the border line takes a different course than in
the mexican lowlands. There are some neotropical genera, whose species
go up until Texas or California.
There has been this faunal and floristic exchange between North- and South
America, so the exact border between Neotropical and Nearctic Region is
difficult to define. But I think it is commonly put into Mexico.

>Plalearkt and nearktis is holoarktis ?

Yes, I think so. Both are related to the continent Laurasia, if I am right.
That is the old northern continent, opposed to Gondwana, the southern continent.

>What is called America North and South?

I think the isthmus of Panama is commonly supposed to be the border between
North and South America.....

I am now not quite sure how the Caribean islands and Central America relate
to this, they seem to have something to do with the pacific region....
Maybe someone wants to continue...

Neoterra?

I have never heard of this.

Often one divides up the Neotropical region in Tropical South America and
Temperate South America.
While Tropical South America has strong affinities across the Atlantic with
the Ethiopian Region and, across the pacific, with the Pacific Islands,
Temperate South America has affinities via Antarctica with Australia, Southern
Africa and New Zealand....

The very southern end of South America, i.e. Tierra del Fuego and the islands
of Magelan, is sometimes called, if I remember correctly, Terra Finis

I think the problem will be to extract from various, partly or completely
competing schools (panbiogeography, cladistics, conservation unities, Wallacian
biogeography etc....) the most conclusive and convincing informations and
synthesize them again in a good manner...

I don't even know whether zooareas make any sense.....I don't know any area
on earth where zoology can be decoupled from botany or geology...
