“…Globally it is listed as Least Concern due to its extensive distribution and local large population size (Birdlife International, 2015), but the species is steadily declining in Scandinavia and in Southern Europe (Birdlife International, 2015;Lehikoinen, Green, Husby, Kålås, & Lindström, 2014). The rock ptarmigan is an ample flyer and dispersal distances up to 300 km have been reported (Gardarsson & Bossert, 1997), but it tends to avoid crossing unsuitable matrix habitat (Bech et al, 2013;Bech, Boissier, Drovetski, & Novoa, 2009;Novoa et al, 2014).…”

The island biogeography theory is one of the major theories in ecology, and its applicability to natural systems is well documented. The core model of the theory, the equilibrium model of island biogeography, predicts that species diversity on an island is positively related to the size of the island, but negatively related by the island's distance to the mainland. In recent years, ecologists have begun to apply this model when investigating genetic diversity, arguing that genetic and species diversity might be influenced by similar ecological processes. However, most studies have focused on oceanic islands, but knowledge on how the theory applies to islands located on the mainland (e.g., mountain islands, forest islands) is scarce. In this study, we examined how the size and degree of isolation of mountain islands would affect the genetic diversity of an alpine bird, the rock ptarmigan ( Lagopus muta ). Within our study area, we defined the largest contiguous mountain area as the mainland, while smaller mountains surrounding the mainland were defined as islands. We found that the observed heterozygosity ( H o ) was significantly higher, and the inbreeding coefficient ( F is ) significantly lower, on the mainland compared to islands. There was a positive significant relationship between the unbiased expected heterozygosity ( H n.b. ) and island size (log km 2 ), but a negative significant relationship between H o and the cost distance to the mainland. Our results are consistent with the equilibrium model of island biogeography and show that the model is well suited for investigating genetic diversity among islands, but also on islands located on the mainland.

“…This is especially evident in alpine species (Segelbacher & Storch 2002;Fedy et al 2008) where naturally fragmented habitat may be viewed as an 'alpine archipelago' (Burkey 1995). These high-altitude habitat patches and the species they harbour can provide significant insight into past biogeographical change (Floyd et al 2005;Galbreath et al 2009) and serve as useful models for predicting future responses to anthropogenic climate change (Bech et al 2013).…”

Naturally subdivided populations such as those occupying high-altitude habitat patches of the 'alpine archipelago' can provide significant insight into past biogeographical change and serve as useful models for predicting future responses to anthropogenic climate change. Among New Zealand's alpine taxa, phylogenetic studies support two major radiations: the first correlating with geological forces (Pliocene uplift) and the second with climatic processes (Pleistocene glaciations). The rock wren (Xenicus gilviventris) is a threatened alpine passerine belonging to the endemic New Zealand wren family (Acanthisittidae). Rock wren constitute a widespread, naturally fragmented population, occurring in patches of suitable habitat over c. 900 m in altitude throughout the length of the South Island, New Zealand. We investigated the relative role of historical geological versus climatic processes in shaping the genetic structure of rock wren (N = 134) throughout their range. Using microsatellites combined with nuclear and mtDNA sequence data, we identify a deep north-south divergence in rock wren (3.7 ± 0.5% at cytochrome b) consistent with the glacial refugia hypothesis whereby populations were restricted in isolated refugia during the Pleistocene c. 2 Ma. This is the first study of an alpine vertebrate to test and provide strong evidence for the glacial refugia hypothesis as an explanation for the low endemicity central zone known as the biotic 'gap' in the South Island of New Zealand.

As of 2014, 89 species have been legally designated as "nationally endangered species of wild fauna and flora," including 37 avian species in Japan. To facilitate the breeding of endangered species and the maintenance of protected habitats, a program for the rehabilitation of natural habitats and maintenance of viable populations is being established by the Ministry of the Environment and other related ministries for 49 of the species on the above list. The programs have already been established for 15 such avian species, and are currently managed by zoos or local authorities. Maintaining genetic diversity is necessary to ensure the stable procreation of endangered species. A decline in breeding potential due to inbreeding can be prevented by careful maintenance of genetic diversity. In addition to the prevention of inbreeding depression, the maintenance of genetic diversity safeguards species' resistance to pathogens, as well as their capacity to cope with environmental change. This manuscript reports on the status of currently available genetic information for nationally endangered avian species in Japan, with a particular focus on the 15 species included in the conservation and propagation program. In the NCBI "Nucleotide" database, 315 entries were related to sequence information from the 15 endangered species. Mitochondrial DNA-related sequences constituted 238 (75.6%) of these entries. In the NCBI "Genome" database, genome sequence entries for three species were found. As is the case with mitochondrial DNA, microsatellite loci are very useful for endangered species conservation to evaluate genetic diversity. However, information about the endangered avian species' microsatellite makers is limited. This situation could have a considerable negative impact on captive breeding projects in particular. Hence, the development of microsatellite markers for these species is a priority.
