Sex- and age-related variation in survival and cost of first reproduction in Greater Flamingos
2001
International audience; We analyzed survival of breeding Greater Flamingos, Phoenicopterus ruber roseus, using the capture histories of 2000 breeding birds ringed as chicks and resighted at their natal colony in the Camargue, southern France. As found in previous analyses, recapture probability varied according to year, sex, and age of the bird, and annual survival was strongly affected by winter severity. However, by using a much larger data set than in earlier analyses, we detected previously nonsignificant effects. Indeed, for the first time, sex and age of the bird were found to influence annual survival probability. We tested the hypothesis that the observed sex-related difference in s…
Aquatic biodiversity and saline lakes: Lake Bogoria National Reserve, Kenya
2003
Lake Bogoria, in the Rift Valley of Kenya is an extreme saline lake (conductivity 40–80 mS cm-1, alkalinity 1500 m equ 1-1). It is hydrologically more stable than the other, endorheic lakes in Kenya, because it is deep — maximum depth at present just over 10 m in an area of 3000 ha — and so does not have periods when it is dry. It is ecologically simple, with only one species dominating the phytoplankton — the cyanobacterium ‘spirulina’, Arthrospira fusiformis. Its biomass and productivity were very high — biomass between 38 and 365 μg 1-1 chlorophyll ‘a’ and 3.4–21 x 103 coils ml-1 and net production between 0.24 and 1 gm C m3 h, the latter in a narrow zone of less than a metre. There were…
Data from: Evidence for an association between post-fledging dispersal and microsatellite multilocus heterozygosity in a large population of greater …
2014
Dispersal can be divided into three stages: departure, transience and settlement. Despite the fact that theoretical studies have emphasized the importance of heterozygosity on dispersal strategies, empirical evidence of its effect on different stages of dispersal is lacking. Here, using multi-event capture-mark-recapture models, we show a negative association between microsatellite multilocus heterozygosity (MLH; 10 loci; n = 1023) and post-fledging dispersal propensity for greater flamingos, Phoenicopterus roseus, born in southern France. We propose that the negative effects of inbreeding depression affects competitive ability and therefore more homozygous individuals are more likely to di…

Flamingo studies: a general introduction.
2017
28 pages; International audience; Flamingos are among the most amazing birds in the world. The first part of this chapter provides a general introduction to the various extant species of flamingos, including their physical descriptions, unique characteristics, numbers in the wild, and geographical distributions. The second part depicts a brief history of the discovery and scientific study of flamingos, from the earlier accounts dating from the 16th century to the development of the first long-term studies of banded populations in the second half of the 20th century. The third and final part of this chapter offers some perspectives for future research.
