Abstract:
The Fennoscandian population of the Lesser White-fronted Goose Anser erythropus (LWfG) is on the verge of extinction and migrates from northern Fennoscandia to Greece on a regular seasonal basis. For the first time, diet selection was investigated during two years at Kerkini Lake, a wintering site in Greece. The relative use of LWfG’s feeding habitats was systematically recorded by visual observations of the LWfG flocks. Food availability was measured by the relative cover of available vegetation types while the diet composition was determined by the microhistological analysis of droppings. In addition, we determined crude protein, neutral detergent fibre, acid detergent fibre and acid detergent lignin content of the most preferred plant species by LWfG and all vegetation categories that contributed to LWfG diet in the middle of the duration of their stay at Kerkini Lake and after their departure from the lake. LWfG feeding habitat was exclusively marshy grassland in water less than 5 cm deep up to 300–400 m away from the shore. LWfG selected a diverse number of plant species (33), however, grass made up the 58% of their diets. The most preferred plant species were Echinochloa crus-galli, Cyperus esculentus, Scirpus lacustris and Ranunculus sceleratus. LWfG departed from Kerkini Lake in mid-December to the Evros Delta (Thrace, eastern Greece), when either food availability falls in very low levels or flooding occurred in their main feeding habitat. Consequently, as long as food and habitat resources are available for LWfG, it is very likely that the birds will winter mainly at Kerkini Lake and not at the Evros Delta, which will contribute to further minimisation of the theoretical risk of accidental shooting of LWfG at the latter wintering habitat. Thus, future conservation actions should primarily focus on the grassland improvement at Kerkini Lake enhancing the availability of food resources for LWfG (mainly grasses) and the protection of the feeding habitat from flooding.

Abstract:
Phylogenetic incongruence can be caused by analytical shortcomings or can be the result of biological processes, such as hybridization, incomplete lineage sorting and gene duplication. Differentiation between these causes of incongruence is essential to unravel complex speciation and diversification events. The phylogeny of the True Geese (tribe Anserini, Anatidae, Anseriformes) was, until now, contentious, i.e., the phylogenetic relationships and the timing of divergence between the different goose species could not be fully resolved. We sequenced nineteen goose genomes (representing seventeen species of which three subspecies of the Brent Goose, Branta bernicla) and used an exon-based phylogenomic approach (41,736 exons, representing 5887 genes) to unravel the evolutionary history of this bird group. We thereby provide general guidance on the combination of whole genome evolutionary analyses and analytical tools for such cases where previous attempts to resolve the phylogenetic history of several taxa could not be unravelled. Identical topologies were obtained using either a concatenation (based upon an alignment of 6,630,626 base pairs) or a coalescent-based consensus method. Two major lineages, corresponding to the genera Anser and Branta, were strongly supported. Within the Branta lineage, the White-cheeked Geese form a well-supported sub-lineage that is sister to the Red-breasted Goose (Branta ruficollis). In addition, two main clades of Anser species could be identified, the White Geese and the Grey Geese. The results from the consensus method suggest that the diversification of the genus Anser is heavily influenced by rapid speciation and by hybridization, which may explain the failure of previous studies to resolve the phylogenetic relationships within this genus. The majority of speciation events took place in the late Pliocene and early Pleistocene (between 4 and 2 million years ago), conceivably driven by a global cooling trend that led to the establishment of a circumpolar tundra belt and the emergence of temperate grasslands. Our approach will be a fruitful strategy for resolving many other complex evolutionary histories at the level of genera, species, and subspecies.

Abstract:
Fieldwork was carried out between 6th June and 10th August 2015 at the western macro-slope of the Polar Urals and the eastern Bolshezemelskaya Tundra, Russia. In the Bolshaya Rogovaya River basin area, only one LWfG pair with five juveniles was located. However, the numbers of Bean Geese were high, with 92 adults and at least 58 juveniles in the same area. In the Polar Urals, Lesser White-fronted Geese were found on the rivers or watershed lakes in June, but repeated observations carried out in July and early August did not confirm the presence of LWfG, but also here many broods of Bean Goose were observed. Altogether, three broods of LWfG were found in one flock. One adult male was caught by a hoop net during fieldwork and equipped with a solar powered GPS satellite transmitter. This male LWfG migrated southwards along the Ob river valley, through Kazakhstan, but instead of crossing over to the western side of the Caspian Sea as expected, he was tracked to Uzbekistan and Turkmenistan. This is the first time that a Lesser White-fronted Goose has been tracked to this probably very important wintering area which is situated in the border area between Uzbekistan and Turkmenistan. By 7th January 2016 the bird was still alive and with a functioning transmitter.

Abstract:
We carried out a field survey of wintering Lesser White-fronted Geese in the Aras water reservoir in the Nakhchivan Autonomic Republic in the period 20th-24th January 2015. We also surveyed the adjoining flood-plain area of the Aras River valley within Sadarak district near the border of Iran and Turkey in the same period. Only four small flocks of Lesser White-fronted Geese were located, of which the largest being 80 individuals. These observations together with tracking and location data from satellite transmitter tagged birds proves that the whole area of the Aras River valley from the border of Turkey to the Aras reservoir dam, serves as a wintering ground for the species. Considering their high importance, the wetlands of the Aras reservoir and the Sadarak district should be designated as a strictly protected area.The survey also covered numbers and distribution of other waterbird species in the area. Within the Azerbaijan part, more than 25000 individuals of waterfowl and shorebirds overwinter, which qualifies this important area to the list of important RAMSAR wetlands.
