“…Previously identified plumage differences between Italian sparrows and house and Spanish sparrows (Summers-Smith, 1988;Hermansen et al, 2011) combined with evidence that post-zygotic reproductive barriers are strongest at the Italian sparrow range boundaries , and a lack of hybridization in sympatry between Italian and Spanish sparrows Trier et al, 2014) provide a strong argument that the Italian sparrow is a distinct homoploid hybrid species (Sangster et al, 2015). Additional evidence presented here, of RI acting on a diagnostic male plumage trait at one of the range boundaries, strengthens that conclusion.…”

“…The Italian sparrow (Passer italiae Vieillot) is a homoploid hybrid species that originated through hybridization between house sparrows (Passer domesticus L.) and Spanish sparrows (Passer hispaniolensis Temminck) Hermansen et al, 2011;Trier et al, 2014;Sangster et al, 2015). It occupies the whole Italian peninsula and some Mediterranean islands (Summers-Smith, 1988; Fig.…”

Strong selection on male plumage in a hybrid zone between a hybrid bird species and one of its parents

Homoploid hybrid speciation (HHS) requires reproductive barriers between hybrid and parent species, despite incomplete reproductive isolation (RI) between the parents. Novel secondary sexual trait values in hybrids may cause prezygotic isolation from both parents, whereas signals inherited by the hybrid from one parent species may cause prezygotic isolation with the other. Here we investigate whether differences in male plumage function as a premating barrier between the hybrid Italian sparrow and one of its parent species, the house sparrow, in a narrow Alpine hybrid zone. Italian sparrow male plumage is a composite mosaic of the parental traits, with its head plumage most similar to its other parent, the Spanish sparrow. We use geographical cline analysis to examine selection on three plumage traits, 75 nuclear single nucleotide polymorphisms (SNPs) and hybrid indices based on these SNPs. Several SNPs showed evidence of restricted introgression in the Alps, supporting earlier findings. Crown colour exhibited the narrowest plumage cline, representing a 37% (range 4-65%) drop in fitness. The cline was too narrow to be due to neutral introgression. Only crown colour was significantly bimodal in the hybrid zone. Bimodality may be due to RI or a major QTL, although fitness estimates suggest that selection contributes to the pattern. We discuss the implications with respect to HHS and the species status of the Italian sparrow.

“…As such, it is not feasible to identify this specimen beyond genus. However, it is notable that of all the compared specimens the closest match on morphological and morphometric grounds is S. molybdophanes, an ostrich recently promoted to full species status (Sangster et al, 2015; see also Miller et al, 2011) and currently restricted to the horn of Africa.…”

Middle Pleistocene vertebrate fossils from the Nefud Desert, Saudi Arabia: Implications for biogeography and palaeoecology

The current paucity of Pleistocene vertebrate records from the Arabian Peninsula-a landmass of over 3 million km 2-is a significant gap in our knowledge of the Quaternary. Such data are critical lines of contextual evidence for considering animal and hominin dispersals between Africa and Eurasia generally, and hominin palaeoecology in the Pleistocene landscapes of the Arabian interior specifically. Here, we describe an important contribution to the record and report stratigraphically-constrained fossils of mammals, birds and reptiles from recent excavations at the site at Ti's al Ghadah in the southwestern Nefud Desert. U series and combined US-ESR analyses of Oryx sp. teeth indicate that the assemblage is Middle Pleistocene in age and dates to ca. 500 ka. The identified fauna is a biogeographical admixture that consists of likely endemics and taxa of African and Eurasian affinity and includes extinct and extant (or related Pleistocene forms of) mammals (Palaeoloxodon cf. recki, Panthera cf. gombaszogenis, Equus hemionus, cf. Crocuta crocuta, Vulpes sp., Canis anthus, Oryx sp.), the first Pleistocene records of birds from the Arabian Peninsula (Struthio sp., Neophron percnopterus, Milvus cf. migrans, Tachybaptus sp. Anas sp., Pterocles orientalis, Motacilla cf. alba) and reptiles (Varanidae/Uromastyx sp.). We infer that the assemblage reflects mortality in populations of herbivorous animals and their predators and scavengers that were attracted to freshwater and plant resources in the inter-dune basin. At present, there is no evidence to suggest hominin agency in the accumulation of the bone assemblages. The inferred ecological characteristics of the taxa recovered indicate the presence, at least periodically, of substantial water-bodies and open grassland habitats.

“…Sangster et al (2015) recommended that the New World form hudsonicus (American Whimbrel) be treated as a species distinct from the Eurasian Whimbrel N. phaeopus based on previously published evidences and a new molecular phylogenetic analysis using available mtDNA datasets. The separation of these two taxa had already been proposed independently by Livezey (2010) based on a cladistic analysis of phenotypic characters.…”

ABSTRACT. We present a new update of the list of birds of the state of Rio Grande do Sul, Brazil, based on a thorough review of new records and evidences accumulated from February 2011 to July 2017. This is the fifth update since the first compilation based on a reasonably complete geographic coverage of the state, published by William Belton in 1978, and the second produced by a regional (informal) committee. It is also the first to widely use citizen science contributions available on shared portals and digital databases on the internet. Forty-three taxa were added, resulting in a final list with 704 species, 6.5% more than in the previous assessment in 2010. Two species were replaced due to taxonomic changes. Documentation for inclusions based on unpublished records is indicated or published here. We also updated the documentation of another 20 species previously included in the list. Inclusions represent mainly migrants recorded in the state as vagrants or irregular visitors (22), but also cases of recent range expansion (especially from the north) and previously overlooked resident or migratory taxa. The average rate of additions (over six species per year) was 30% higher than in the previous period and is expected to accelerate. The percentage of accepted species without documented records in the state decreased from 1.8% in 2010 to 0.7% in the current list. We attribute these results to a better spatial and temporal coverage of the state in recent years, mainly due to the increasing contribution of amateurs, who accounted for 60% of the new occurrences. In contrast, the percentage of species documented by museum specimens has decreased steadily over time (currently at 84%). Investment in scientific research and collection of voucher specimens in the state should keep pace with the growing interest birds arouse in society, due to the importance and usefulness of museum specimens.KEYWORDS.
