“…Among the three species in our study, the Kittlitz's plover is unique in that it has low mate-fidelity (Parra et al 2014), uniparental care (Zefania and Sz ekely 2013) and a flexible breeding system (Zefania et al 2010). Conversely, white-fronted and Madagascar plovers have high mate-fidelity (Lloyd 2008;Parra et al 2014), biparental care (Zefania and Sz ekely 2013) and are socially monogamous (Zefania et al 2010). It is expected that effective population size is higher for species characterized by monogamous mating systems than those that are otherwise-comparable but have less-monogamous breeding (Kaeuffer et al 2007), which therefore might retain more diversity within populations and facilitate structuring in monogamous species.…”

Understanding the relative contributions of intrinsic and extrinsic factors to population structure and genetic diversity is a central goal of conservation and evolutionary genetics. One way to achieve this is through comparative population genetic analysis of sympatric sister taxa, which allows evaluation of intrinsic factors such as population demography and life history while controlling for phylogenetic relatedness and geography. We used ten conserved microsatellites to explore the population structure and genetic diversity of three sympatric and closely related plover species in southwestern Madagascar: Kittlitz's plover (Charadrius pecuarius), white-fronted plover (C. marginatus), and Madagascar plover (C. thoracicus). Bayesian clustering revealed strong population structure in the rare and endemic Madagascar plover, intermediate population structure in the white-fronted plover, and no detectable population structure in the geographically widespread Kittlitz's plover. In contrast, allelic richness and heterozygosity were highest for the Kittlitz's plover, intermediate for the white-fronted plover and lowest for the Madagascar plover. No evidence was found in support of the “watershed mechanism” proposed to facilitate vicariant divergence of Madagascan lemurs and reptiles, which we attribute to the vagility of birds. However, we found a significant pattern of genetic isolation by distance among populations of the Madagascar plover, but not for the other two species. These findings suggest that interspecific variation in rarity, endemism, and dispersal propensity may influence genetic structure and diversity, even in highly vagile species.

“…However, probably the single most important factor in oystercatcher population growth has been increased food availability following invasions by alien mussels (mainly Mytilus galloprovincialis, Mytilidae; Hockey et al 2005). ), which exacerbate nest predation (Lloyd & Plagányi 2002;Lloyd 2008). By comparison, white-fronted plovers have disappeared from high-use beaches in the greater Cape Town area (e.g.…”

Medium‐term changes in coastal bird communities in the Western Cape, South Africa

There are few studies of medium-term, quantitative changes in faunal communities in the southern hemisphere. The linear nature of coastlines makes populations of coastal birds easy to count. Repeat surveys of 278 km of coastline in three regions of the Western Cape, South Africa show marked differences in coastal bird community structure over the last 30 years, despite limited human impacts on coastal habitats (mainly increased human disturbance). The total number of birds has not changed, but species richness increased following colonization of the coast by Egyptian geese (Alopochen aegyptiaca, Anatidae) and three species of ibises (Threskiornithidae). Biomass also increased due to greater numbers of large-bodied birds. Contrary to the prediction that large birds are more susceptible to human disturbance, most small birds decreased in abundance. Among waders that breed along the coastline, numbers of African oystercatchers (Haematopus moquini, Haematopodidae) doubled, linked to increased food availability following invasions by alien mussels (Mytilidae). By comparison, numbers of white-fronted plovers (Charadrius marginatus, Charadriidae) decreased by 37% (59% close to Cape Town), at least in part as a result of increasing human disturbance.The greatest decreases occurred among migrant waders (Scolopacidae and Charadriidae), with numbers of the four most abundant species falling by >50%, and both common Calidris species by >90%. Migrant wader populations decreased in all three regions, irrespective of whether surveys were in protected areas or not, suggesting that factors outside the region are driving these trends. Some species may have decreased due to changes in their preferred wintering areas, but others probably reflect population decreases, confirming the generally poor conservation status of migrant waterbirds worldwide.
