“…However, the biogeographic analyses indicate at least one case of ‘upstream colonization’ by E. tenuirostre of the Australo‐Papuan mainland, probably from the Melanesian Archipelago. Recent studies have emphasized the potential of island systems in generating diversity and back‐dispersal to continental land masses (Filardi & Moyle, ; Schweizer et al., ). This might be more common than previously anticipated (Jønsson & Holt, ), especially among highly dispersive ‘tramp’ species such as members of Edolisoma (see also Jønsson et al., ).…”

Aim We derive a new phylogenetic framework of the Indo‐Pacific avian genus Edolisoma based on a dense taxon sampling and use it in an explicit spatiotemporal framework to understand the history of intraspecific diversification dynamics in a ‘great speciator’, the Cicadabird Edolisoma tenuirostre/remotum complex. Location The Indo‐Pacific island region, Australia and New Guinea. Taxon Corvoid passerine birds (Passeriformes). Methods We used Bayesian phylogenetic methods (beast) to construct a time‐calibrated molecular phylogeny of all 19 species in the genus Edolisoma and 27 of 29 subspecies of the E. tenuirostre/remotum complex (previously Coracina tenuirostris) primarily based on one mitochondrial DNA marker. Ancestral area reconstruction methods (‘BioGeoBEARS’) were used to infer the historical biogeography of the genus. We used population‐level analyses to assess intraspecific phylogeography and a molecular species delimitation test to evaluate the current taxonomy. A morphometric dataset was used to discuss differential dispersal ability among taxa. Results Edolisoma originated in the late Miocene and diversification within the E. tenuirostre/remotum complex began in the Pleistocene. Within the North Melanesian and North Wallacean archipelagos, which have experienced several waves of diversification, we find significant patterns of genetic isolation by distance, but not within the Australo‐Papuan ‘mainland’, which was recently back‐colonized from these archipelagos. Based on the phylogeny, we suggest several taxonomic changes. We also discuss evidence of taxon cycles within Edolisoma based on correlations of species age, elevational ranges and dispersal ability. Main conclusions The biogeographical history and patterns of differentiation between phylogroups within E. tenuirostre support the importance of barriers to gene flow in island systems. Examples of both recent genetic exchange across significant sea barriers and differentiation across much smaller water gaps suggest complex dispersal and diversification dynamics. The capacity for dispersal away from islands, and gradual shifts in dispersal ability in relation to the geographical setting, is supported as important factors in generating a ‘great speciator’.

“…Although Australasia and the Indo‐Pacific is inhabited by some other nectarivorous birds, including non‐passerine parrots such as the lories and lorikeets (family Psittacidae: tribe Loriinae), this group is thought to have radiated considerably later than the honeyeaters, with most of the diversification having taken place in the last 5 million years (Schweizer et al. ). In comparison with honeyeaters, this group is characterized by comparatively low levels of sympatric species diversity (Schweizer et al.…”

Adaptive radiation and the evolution of nectarivory in a large songbird clade

et al. 2019

The accumulation of exceptional ecological diversity within a lineage is a key feature of adaptive radiation resulting from diversification associated with the subdivision of previously underutilized resources. The invasion of unoccupied niche space is predicted to be a key determinant of adaptive diversification, and this process may be particularly important if the diversity of competing lineages within the area, in which the radiation unfolds, is already high. Here, we test whether the evolution of nectarivory resulted in significantly higher rates of morphological evolution, more extensive morphological disparity, and a heightened build‐up of sympatric species diversity in a large adaptive radiation of passerine birds (the honeyeaters, about 190 species) that have diversified extensively throughout continental and insular settings. We find that a large increase in rates of body size evolution and general expansion in morphological space followed an ancestral shift to nectarivory, enabling the build‐up of large numbers of co‐occurring species that vary greatly in size, compared to related and co‐distributed nonnectarivorous clades. These results strongly support the idea that evolutionary shifts into novel areas of niche space play a key role in promoting adaptive radiation in the presence of likely competing lineages.

“…Joshua & Parker, 1993;Schmutz & Prus, 1987) Lories, with 53 species (Collar, 1997), are a very diverse group of parrots. It has been suggested that they arose in Papua New Guinea in the middle Miocene (at relatively recent times) (Joshua, 1994;Schweizer et al, 2011;Schweizer, Wright, Peñalba, Schirtzinger, & Joseph, 2015) and ulteriorly dispersed colonizing many land territories of the Indo Australasian Pacific Ocean.…”

“…(Collar, 1997;Forshaw & Cooper, 1989). "Nectar may have been, in this part of the world, a spatially widespread, and underutilized niche which would have allowed Lories to disperse, and successfully establish populations on oceanic islands, which was then followed by allopatric speciation, and eventually secondary sympatry through range expansion" (Schweizer et al, 2011(Schweizer et al, , 2015.…”

With colourful plumage, charismatic character and vocal learning abilities, parrots are one of the most striking and recognizable bird groups. Their attractiveness has drawn human attention for centuries, and members of the Psittaciformes order were, also, among the first avian species to be subject to cytogenetic studies which have contributed to understand their taxonomic and evolutionary relationships.We present here the karyological results collected by the study of thirteen parrot species new to karyology. These results are additionally supported by G banded preparations obtained in five species.The order Psittaciformes is an interesting example of a, typically, non migratory avian lineage with Gondwanaland origin, whose evolutionary radiation has been shaped by the Cenozoic geographic and climatic events that affected the land masses derived from the Gondwanaland continental split.We discuss the results of our studies, in conjunction with the previously compiled Psittaciformes cytogenetic data to delineate a picture of the chromosomal evolution of the order, concurrently with the biogeographic history of the lands in the southern Hemisphere.Considering the available data on parrot cytogenetics, a "standard parrot karyotype pattern" is proposed for evolutionary comparisons.Several biogeographic, and phylogenetically related "karyogram patterns" are also identified, and mechanisms of chromosome rearrangement that associate this patterns among them, and with the standard parrot karyotype pattern are proposed. These schemes on parrot chromosomal variation are discussed in relation to the general avian chromosome evolutionary theses proposed by cytogenetic and molecular genomic researchers.
