Figure 2 in Genetic and morphological evidence for two species of Leucocarbo shag (Aves, Pelecaniformes, Phalacrocoracidae) from southern South Island of New Zealand
Figure 2. Carunculation and gular pouch colour in pied morphs of Chatham Island, Otago, and Foveaux shags. The Chatham Island shag (left) has pronounced bright orange facial caruncles and gular pouch; the Otago shag (centre) has equal frequencies of small bright orange facial caruncles (shown) and dark orange scattered papillae (not shown), and bright to dark orange (shown) or purple (not shown) gular pouch; the Foveaux shag (right) has scattered dark orange papillae (shown) and bright to dark orange (shown) gular pouch.

Figure 1. Distributional and morphological data for Otago, Foveaux, and Chatham Island shags. A, map of New Zeal- and showing the location of the Chatham Islands and Otago/Foveaux Strait study sites. Blue circles represent the prehistoric distribution of Otago shag outside the study area. B, distribution of Chatham Island shag breeding colonies and roosting sites (green circles). The Chatham Island shag exhibits pied plumage only (white pie chart) with pronounced bright orange caruncles in breeding plumage (orange pie chart). C, distribution of Otago (blue circles) and Foveaux (red circles) shag breeding colonies and roosting sites. Otago shag populations have 20–30% pied morphs (pie charts; black: dark-bronze; white: pied) and 50:50% small bright orange caruncles: dark orange scattered papillae in prenuptial breeding plumage (pie charts; yellow: small bright orange caruncles; grey: dark orange scattered papillae) compared with 50– 60% pied morph and dark orange scattered papillae in prenuptial breeding plumage in the Foveaux shag. In (C), multiple breeding colonies and roosting sites are represented at the following locations (from north to south): Otago Peninsula including Long Beach, Aramoana, Otago Harbour, Taiaroa Head, Boulder Beach, Papanui Beach, Allans Beach, Wharekakahu Island, and Gull Rocks; Seal Rocks and Ruapuke Island; Easy Harbour and Shag Rock. In (C), the Leucocarbo shag species illustrating plumage characters are: pied morph (Otago shag), bronze morph (Foveaux shag), small caruncles (Otago shag), and scattered papillae (Foveaux shag).

Genetic insights into the range expansion of the cattle egret (Pelecaniformes: Ardeidae) in Brazil and population differentiation between the native and colonized areas
<p>Gnotypes of Cattle Egrets (Bubulcus ibis) at 14 microsatellite loci amplified using the primers in Table S1 of the article. The protocols are described in Appendix S1 of the Supplementary Material of Miño et al. 2022.</p> <p>Bubulcus ibis ibis naturally expanded its range by flying over the Atlantic Ocean from Africa or Europe (native range) to South America, being first reported in Suriname towards the end of the 19th century. However, the source populations of the birds colonising South America still remains unclear. Here, to o gain insights into the possible source and routes of colonisation, we characterize the levels of diversity at nuclear microsatellites and assessed the genetic structure of populations from central and southern Africa (n = 129, 13 sites, five countries) and from different latitudes along Brazil (n = 166, six sites). We found overall high levels of genetic diversity in the colonised range, which fit the expectations for organisms with long-distance dispersal potential, rapid growth rates and feeding plasticity. Noteworthy, the results from population-genetic analyses based on different assumptions concurrently agree in indicating that cattle egrets from Brazil harbour a genetic pool distinct from populations from Africa, suggesting restricted contemporary gene flow between these ranges. The lack of genetic differentiation among the African populations did not enable us to identify the source of Brazilian cattle egrets. Fernando de Noronha Archipelago, off the Brazilian northeastern coast, had the highest proportion of the African allelic ancestry. Approximate Bayesian computation analyses supported a scenario of population growth in Africa with subsequent expansion to Brazil and migration from Africa to Brazil at the time of colonisation. We discuss our findings in light of the anthropogenic changes that may have promoted the range expansion of this egret into Brazil.</p>
