“…Investigations into these barriers can involve (1) comparisons of conspecific populations, but these populations may not form new species if the barrier does not last sufficiently long for reproductive isolation to evolve, or (2) comparisons of sister species, but differences between sister species may not represent the barriers that initiated speciation is often unknown could be collated for all species. Populations or species for which population genetic structure and gene flow appear to have been strongly affected by human activities (e.g., overexploitation or transplantation; e.g., Short-tailed Albatross Phoebastria albatrus, Eda et al 2012) or that breed primarily inland (i.e., not in association with marine waters; e.g., White Pelican Pelecanus erythrorhynchos) also were not included. Interpretations were sometimes complicated by taxonomy, especially as subspecies are sometimes elevated to full species based on molecular data.…”

Speciation in seabirds: why are there so many species…and why aren’t there more?

Speciation-the multiplication of species through the evolution of barriers to reproduction between populations-plays a central role in evolution since it enables two or more populations to adapt and evolve independently. However, mechanisms of speciation are notoriously difficult to study and poorly understood. Seabirds provide useful models to investigate factors that may promote or inhibit speciation because their ecology and evolutionary genetics are relatively well understood. Here I review population genetic studies of seabirds to test the importance of six factors with the potential to disrupt gene flow enough to result in speciation. Over 200 studies, including over 100 species, have been published to date. Most show evidence of restrictions in gene flow. Physical (geographic) barriers to dispersal are clearly important: conspecific populations that are separated by large expanses of land or ice show evidence of restricted gene flow, and sister species often are separated by physical barriers to gene flow. However, many species of seabirds show evidence of restrictions in gene flow in the absence of physical barriers to dispersal. Study results indicate that differences in ocean regimes, nonbreeding distributions, foraging distributions during the breeding season, and breeding phenology also can disrupt gene flow enough to lead to speciation. Of these, physical isolation and differences in ocean regime appear to be the most important. Philopatry alone may be sufficient to result in reproductive isolation, but usually it acts in combination with other barriers to gene flow. The effects of many other potential influences on gene flow need to be investigated more thoroughly, including colony distribution/location, wind, interspecific interactions, environmental stability/variability, variation in phenotypic traits associated with mate choice (morphology, behaviour, vocalisations) and intrinsic (genomic) incompatabilities. Recent advances in genome sequencing, especially if used in combination with ecological tools such as geolocators and new methods for data interpretation, are opening exiting new avenues to test the importance of various behavioural, ecological, demographic and genomic factors in reducing or promoting gene flow and so affecting speciation.

Translocation and hand‐rearing result in short‐tailed albatrosses returning to breed in the Ogasawara Islands 80 years after extirpation

Restoration or establishment of colonies using translocation and hand-rearing can be an effective tool for conserving birds. However, well-designed post-release evaluation studies for long-lived species are rarely implemented. We investigated the attendance and breeding attempts of hand-reared short-tailed albatross (STAL) Phoebastria albatrus chicks (n = 69) translocated to a historic breeding island in the Ogasawara Islands, 350 km from the source colony, for 8 consecutive years after the first translocation. Thirty-nine percent of hand-reared birds (n = 27) returned to the translocation site at least once per breeding season, of which 67% (n = 18) also visited the natal island. The number of hand-reared birds returning each year was lower at the translocation site (mean: 0.3-2.3 birds per day) versus the natal island (0.4-3.5 birds per day). The first breeding attempt occurred 5 years after the first translocation. Three pairs (producing three chicks) recruited to the translocation site or neighboring islands and five pairs (producing nine chicks) recruited to the natal island by 8 years after the first translocation. Every hand-reared bird that raised a chick paired with a naturally reared bird. At the translocation site and neighboring islands, two hand-reared birds paired with a mate from the natal island and a breeding colony 1850 km away, respectively, while the parents of the third chick were unknown. Their breeding at the translocation region was observed among conspecific social attractants (decoys, audio playback; one pair) or congeners (two pairs). Our preliminary results suggest that even though more translocated and hand-reared albatrosses visited and recruited to their natal island compared to the translocation site, the early re-establishment of breeding by short-tailed albatrosses in the Ogasawara Islands 80 years after extirpation would not have occurred without the initial translocation effort. Further study is needed, however, to fully understand formation of breeding colonies beyond conspecific attraction and philopatry.

The Present Status of Available Genetic Information for Avian Species Distributing in Japan and on the List of “Nationally Endangered Species of Wild Fauna and Flora”

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.
