Taxonomic Merge 95653 (הועלה ב 2021-07-30)

Schiaffini and Moratelli (2020) demonstrates that the subspecies described under the tayra (Eira barbara), all but one of which were described before 1920 without modern contexts for how mammalian subspecies are typically defined, are not tenable as valid taxa. They do not express distinctive morphologic traits that can be reliably identified. Populations retain consistent gene flow between each other, indicating there have not been any genetic isolation that would lead to the development of recognizable taxa. Skull shape correlates to climates, not taxonomic concepts, and is more pronounced between sexes than the traditionally defined subspecies.

Are subspecies (of Eira barbara) real? (ציטוט)

Hello, @marcelo_aranda. The tayra has recently been described as monophyletic. What do you think? Do you think this would be an uncontroversial swap?

Hello @bobby23 I am not a taxonomist, but I believe that in the past the description of subspecies has been abused. I understand that taxonomy is very dynamic and there will always be taxonomists who tend to unify and others who tend to fragment. As you know, in 2020 the Illustrated Checklist of the Mammals of the World was published and seven subspecies were still recognized for the tayra that, in my opinion, had no sustenance. As long as there is no clarity about the real state of isolation of some populations, I agree with the change. Greetings.

Thank you for your thoughts, @marcelo_aranda. I believe we have the same position on mammal subspecies. I will proceed with the change.

@bobby23 now I have a query for you. In Mexico Neotamias durangae solivagus is managed as a subspecies; however, its population has been naturally isolated for a long time and some authors (Ramirez-Pulido et al, 2014) consider it a species. In this case, I agree with Neotamias solivagus as a different species from Neotamias durangae. What you think?

Looking into it, I see that Neotamias solivagus is considered a valid taxon by the Mammal Diversity Database (as seen here). I would be happy to integrate it into iNaturalist's taxonomy, but I hope it's understandable if I don't do it immediately. I have a backlog of mammal revisions to make, and I am currently prioritizing cleaning up Carnivora before moving on to other mammal taxa.
