Ponti, Arcones, Ferrer, Vieites. 2018. Productivity as the main factor correlating with migratory behaviour in the evolutionary history of warblers. J. Zool.
[abstract & supp.info] [pdf here]
Abstract
The evolution of migration in birds and its causes are still subject of debate. Recent studies tracking current bird migration have identified peaks in net primary productivity (NPP) as a main driver of bird migratory behaviour. However, it is unclear which variables may have played a major role in the evolution of bird migration at deeper phylogenetic levels. Here, we used phylogenetic comparative methods to assess whether the evolutionary patterns of migratory distances, as a proxy for migratory behaviour, are correlated with several biometric, climatic and productivity variables in a phylogenetic context, using Sylvia warblers as a case study. Our results recover NPP in the breeding range and during the breeding season as the variable with stronger positive correlation with migratory distances, being always included in the best models considering all potential variables. Several climatic variables show a correlation with the evolution of migration, but those are also tightly correlated with NPP. Among morphological variables, migratory lineages tend to have longer wings than sedentary ones. Although NPP has been identified as a driver of migratory behaviour in current species, in a phylogenetic scale it is not possible to disentangle if it was a main driver in the evolution of bird migratory behaviour or a consequence of it, yet migration and NPP seem to be tightly related today and along the long evolutionary history of these passerines.
There are taxonomic remarks in the supporting information file.

I'm interested by this part. How get it?
Oh! it's not surprising but Parophasma galinieri is embedded within the genus Sylvia stricto sensu as Sylvia (Sylvia) galinieri (if we consider Sylvia and Curruca as a subgenera of Sylvia).

Thanks to Jean-Marc Pons, I've just read it through for the first time; there's a lot to fascinating work to absorb... I'll need to take it step by step...!

Can anybody explain to me in layman's terms why if Western Subalpine Warbler is split it becomes Sylvia iberiae and not Sylvia inornata
Jim LeNomenclatoriste
Je suis un mignon petit Traquet rubicole
inornata is embedded within the taxon moltoni according to their result, so inornata becomes a junior synonym of subalpina. Iberiae is the only name available for the Western Subalpine Warbler

Yes, this is basically what they say.
(They make inornata a junior synonym of subalpina and a senior synonym of moltonii, and argue that, should the insular populations of Moltoni's Warbler be recognised as taxonomically distinct from the continental populations, they should be called inornata.)
The .pdf and suppl. data are freely downloadable from the publisher's website from here now. (I'm not sure this is deliberate, though; the .html version of the full article doesn't seem to be accessible, and the paper is not flagged as free or open access at https://academic.oup.com/zoolinnean/advance-articles .)

Worth rethinking the English names of this group - we're left with the odd situation now where Sylvia subalpina is the only one that isn't called 'Subalpine' in English . . . :eek!:

But your paintings are different! I've just enjoyed those in the new 'Birds of Cyprus'!:t:

They have a neotype selected in the paper - but I guess one can always argue that the neotype is in conflict with the original illustration??
Edit: Both the lost holotype and the neotype are from near Turin

Sylvia curruca complex
Abdilzadeh, R., Aliabadian, M. & Olsson, U. Molecular assessment of the distribution and taxonomy of the Lesser Whitethroat Sylvia curruca complex in Iran, with particular emphasis on the identity of the contentious taxon, zagrossiensis Sarudny, 1911. J Ornithol (2020). https://doi.org/10.1007/s10336-020-01772-x
Abstract:
The Lesser Whitethroat Sylvia curruca complex continues to provide challenges for ornithologists and taxonomists. One of the remaining outstanding questions concerns the taxonomic identity of the different breeding populations in Iran and in particular zagrossiensis, which inhabits the Zagros mountains. We here used the three mitochondrial genes cyt b, COI and ND2, to evaluate samples of the Lesser Whitethroat complex from Iran. Our data include predominantly samples from the breeding season, and we find evidence of three taxa from Iran, of which two are certainly breeding; althaea from Kopet Dagh in NE Iran and the Kerman mountains, east of the Zagros mountains, SE Iran; and curruca from central Zagros mountains and northwestern Iran. Three samples of halimodendri from the south of Iran were migrating or wintering birds. The taxonomically contentious population from the Zagros mountains is here identified as belonging to the curruca clade, and evidence to recognize zagrossiensis based on molecular data is deemed insufficient.

Disentangling the taxonomic status and phylogeographic structure of Marmora’s (Curruca sarda) and Balearic Warbler (Curruca balearica): a genetic multi-marker approach. Journal of Ornithology, pp.1-10. https://doi.org/10.1007/s10336-021-01885-x
Marmora’s Warbler (Curruca sarda) and Balearic Warbler (C. balearica) are allopatric sibling species and were recently split mostly based on morphological and ethological characteristics. Here we provide the first phylogenetic and phylogeographic analyses of this species complex to support the taxonomic status of C. sarda and C. balearica in light of integrative taxonomy. We sampled the two taxa in most of their breeding ranges and we sequenced three mitochondrial and one nuclear gene region. All C. balearica individuals had private haplotypes for the four markers and formed monophyletic clades. Genetic distances between the two taxa were comparable with those found between other species belonging to the Curruca genus. Furthermore, most of the genetic variance was expressed at the interspecific level, rather than between different populations within taxa or between individuals within populations. Our results strongly support the current taxonomic status of these two warblers as distinct species.

(2023) Admixture and introgression obscure evolutionary patterns in lesser whitethroat complex (Curruca curruca; Passeriformes; Aves). Journal of Avian Biology e03045. https://doi.org/10.1111/jav.03045
Abstract
Determining the limits of species is still a major area of contention, particularly when diagnostic differentiating characters are subtle and there is a contradiction between morphological and genetic data. The lesser whitethroat (LWT) complex Curruca curruca represents an interesting study system to address this issue. Here, we use phylogeny-, admixture- and principal component analysis- (PCA-) based analyses on whole-genome sequence data of the parapatric LWT taxa C. c. curruca, C. c. halimodendri, C. c. zagrossiensis and C. c. althaea to investigate the prevalence and importance of gene flow in a geographical area where morphological evidence suggests a clinal transition between populations. The results suggest that LWT populations of the Zagros Mts zagrossiensis may represent a lineage historically diverged from topotypical curruca, the two lineages later coming into secondary contact with extensive gene flow as a result. There is no evidence of a hybrid zone or cline between zagrossiensis and althaea in the Zagros Mts. On the other hand, there is evidence for gene flow between althaea and halimodendri. The results also show possible evidence of admixture from other populations in the LWT complex, extralimital to the sampled area, but the nature of this needs to be evaluated based on a larger data set.

Can someone more capable than me please explain how this aligns with the recent IOC decision (Apr 28) that 'lumps' minula/margelanica and althaea with curruca/blythi/halimodendri?
