Abstract:

The mid-winter waterbird counts in Iran were initiated by the Department of the Environment in January 1967. The counts focused on pelicans, flamingos, swans, geese, ducks, cranes and coots, but some counts were also made of other species of waterbirds. By the early 1970s, the counts were sufficiently comprehensive to enable estimations to be made of the total numbers of many species of waterbirds present in Iran in the mid-winter period. The overall results of the counts and these population estimates are presented in a series of tables. It was estimated that in an ‘average’ year in the early 1970s, there were approximately 2,000–2,200 pelicans, 48,000–51,000 flamingos, 380–460 swans, 27,000–32,000 geese, 2.0–2.4 million ducks, 2,300–2,800 cranes and 370,000–410,000 coots wintering in Iran. The number of birds reaching Iran in autumn and remaining throughout the winter was greatly affected by weather conditions both in Iran and in the north Caspian region. In mild winters, large numbers of the hardier species, notably the swans Cygnus spp., remained throughout the winter in the north Caspian, while in extremely severe winters, a large part of the Russian wintering populations moved south into northern Iran. In dry years, when many of the wetlands in Khuzestan, central Fars and Seistan remained dry throughout the winter, large numbers of waterbirds continued on south to winter in the Indian subcontinent or Mesopotamia. In the winter of 1969/70, when conditions were unusually mild in northwestern Iran, large numbers of birds overwintered in the wetlands of the Urumiyeh basin in Azarbaijan, but in most years these wetlands froze over in December, and most birds had left the area by the time of the mid-winter counts.

Keywords: genetics

Abstract:

In small and declining populations levels of genetic variability are expected to be reduced due to effects of inbreeding and random genetic drift. As a result, both individual fitness and populations’ adaptability can be compromised, and the probability of extinction increased. Therefore, maintenance of genetic variability is a crucial goal in conservation biology. Here we show that although the level of genetic variability in mtDNA of the endangered Fennoscandian lesser white-fronted goose Anser erythropus population is currently lower than in the neigbouring populations, it has increased six-fold during the past 140 years despite the precipitously declining population. The explanation for increased genetic diversity in Fennoscandia appears to be recent spontaneous increase in male immigration rate equalling 0.56 per generation. This inference is supported by data on nuclear microsatellite markers, the latter of which show that the current and the historical Fennoscandian populations are significantly differentiated (FST = 0.046, P = 0) due to changes in allele frequencies. The effect of male-mediated gene flow is potentially dichotomous. On the one hand it may rescue the Fennoscandian lesser white-fronted goose from loss of genetic variability, but on the other hand, it eradicates the original genetic characteristics of this population.

Abstract:

We estimated the size of 30 defined populations of geese wintering in the Western Palearctic (including five released or reintroduced populations of three species). Fourteen populations were accurately estimated from almost full count coverage or robust sampling and ten were well estimated based on more than 50% of their total being counted. An estimated 5.03 million geese wintered in January 2009, up on 3.10 million in January 1993. Only two populations numbered less than 10,000 birds (Scandinavian Lesser White-fronted Goose and Svalbard/ Greenland Light-bellied Brent Goose, the former being critically small within restricted range). Eighteen populations numbered 10,000–100,000, eight 100,000– 1,000,000 and the largest 1.2 million individuals. Of 21 populations with known longer term trends, 16 are showing significant exponential increases, 4 are stable and one declining. Amongst these same populations, five are declining since the 1990s. Long term declines in productivity were found in 7 out of 15 populations. Amongst most of the 11 populations for which data exist, there were no significant long-term trends in annual adult survival. Improved monitoring, including demographic, is required to retain populations in favorable conservation status.
