I am looking for some guidance towards endemism in moths. There is an appreciable literal account of endemism in butterflies. But literature regarding endemism of moths is scanty.
According to me the factors that drive endemism in vertebrate lineages is altitude (which corresponds to isolation in various direct or indirect aspects). Can this be applied to moths ?
Considering moths, an organism which shows high range of plasticity and tolerance towards adverse environments. Keeping in mind so many examples of global invasion of moths from mainly tropical climates to other countries.
Hi Harsimran:
Moths like butterflies assemblages have been widely used to estimate patterns of beta-diversity in forest ecosystems along an altitudinal gradients in different parts of the world. In the following article the authors found a number of endemic moth species that are restricted to high elevation forests above 900 m, so I would say that moths are also useful as bioindicators of beta diversity along gradients of altitud.

Hi,
there are many published cases of endemic moths speciated in insular systems (e.g. Hawaii) but presumably you are already familiar with them.
As for distributional patterns of endemic moths along elevational gradients, this very interesting paper may be useful:

I hope this helps, all best

Its not so much that altitude drives endemism as it is the result of tectonic uplift. Lowland organisms are continually subject to tectonic uplift over geological time. Such tectonic disruption leads to spatial isolation and the potential for genetic isolation and divergence. This is why sometimes it is possible to find phylogenetic relationships between alpine and coastal species or higher taxa. One may find, for example, in New Guinea at thousands of feet in altitude, communities of plants that are usually characteristic of mangrove environments at the coast. As New Guinea rose from a former geosyncline it lifted the cosatal communities in the process and some survived to now be upland or subalpine. This is why some sea birds nest up in high or inland mountains. As their nesting sites where lifted up the birds kept returning to locations that were higher and higher. Moths are no exception to these processes. Of course some montain systems may be worn down again and so the process may go in reverse and a former mountain endemic now becomes a lowland endemic.
