Cím:Morphological and Genetic Differentiation Among Kentish Plover Charadrius alexandrinus Populations in Macaronesia / Mohammed AlmalkI, Krisztina Kupán, María Cristina Carmona-Isunza, Pedrin López, Ana Veiga, András Kosztolányi, Tamás Székely, Clemens Küpper

Megjegyzések:Macaronesia, a group of archipelagos (Azores, Madeira, Canary Islands and Cape Verde) in the Atlantic Ocean, is one of the global biodiversity hot-spots. However, for species that occur throughout these archipelagos the extent of genetic and morphological differentiation between the archipelagos and mainland Iberia and Africa is often unknown. Here we investigate phenotypic and genetic differentiation of Kentish Plovers Charadrius alexandrinus, the most common breeding shorebird of Macaronesia. We show strong genetic and moderate morphological differences among breeding populations. Our results suggest that although these populations are far from being a species-level endemism, they deserve conservation attention given their uniqueness in terms of genetic variation. Recent loss in suitable breeding sites in Canary Islands and Azores put substantial pressure on the extant plover populations. Further studies of the conservation status and threat to these populations are needed along with a comprehensive conservation action plan to halt population decline and facilitate recovery.

Megjegyzések:Sexual selection determines the elaboration of morphological and behavioural traits and thus drives the evolution of phenotypes. Sexual selection on males and females can differ between populations, especially when populations exhibit different breeding systems. A substantial body of literature describes how breeding systems shape ornamentation across species, with a strong emphasis on male ornamentation and female preference. However, whether breeding system predicts ornamentation within species and whether similar mechanisms as in males also shape the phenotype of females remains unclear. Here, we investigate how different breeding systems are associated with male and female ornamentation in five geographically distinct populations of Kentish plovers Charadrius alexandrinus. We predicted that polygamous populations would exhibit more elaborate ornaments and stronger sexual dimorphism than monogamous populations. By estimating the size and intensity of male (n?=?162) and female (n?=?174) melanin-based plumage ornaments, i.e. breast bands and ear coverts, we show that plumage ornamentation is predicted by breeding system in both sexes. A difference in especially male ornamentation between polygamous (darker and smaller ornaments) and monogamous (lighter and larger) populations causes the greatest sexual dimorphism to be associated with polygamy. The non-social environment, however, may also influence the degree of ornamentation, for instance through availability of food. We found that, in addition to breeding system, a key environmental parameter, rainfall, predicted a seasonal change of ornamentation in a sex-specific manner. Our results emphasise that to understand the phenotype of animals, it is important to consider both natural and sexual selection acting on both males and females.

Cím:Ontogenic differences in sexual size dimorphism across four plover populations / Natalie Dos Remedios, Tamás Székely, Clemens Küpper, Patricia L. M. Lee, András Kosztolányi
Dátum:2015
ISSN:0019-1019
Megjegyzések:Sexual size dimorphism (SSD) among adults is commonly observed in animals and isconsidered to be adaptive. However, the ontogenic emergence of SSD, i.e. the timing ofdivergence in body size between males and females, has only recently received attention.It is widely acknowledged that the ontogeny of SSD may differ between species, but itremains unclear how variable the ontogeny of SSD is within species. Kentish PloversCharadrius alexandrinusand Snowy PloversC. nivosusare closely related wader speciesthat exhibit similar, moderate (c. 4%), male-biased adult SSD. To assess when SSDemerges we recorded tarsus length variation among 759 offspring in four populations ofthese species. Tarsus length of chicks was measured on the day of hatching and up tothree times on recapture beforefledging. In one population (Mexico, Snowy Plovers),males and females differed in size from the day of hatching, whereas growth rates dif-fered between the sexes in two populations (Turkey and United Arab Emirates, bothKentish Plovers). In contrast, a fourth population (Cape Verde, Kentish Plovers) showedno significant SSD in juveniles. Our results suggest that adult SSD can emerge at differ-ent stages of development (prenatal, postnatal and post-juvenile) in different populationsof the same species. We discuss the proximate mechanisms that may underlie thesedevelopmental differences.

Megjegyzések:The adult sex ratio (ASR) is a fundamental concept in population biology, sexual selection, and social evolution. However, it remains unclear which demographic processes generate ASR variation and how biases in ASR in turn affect social behaviour. Here, we evaluate the demographic mechanisms shaping ASR and their potential consequences for parental cooperation using detailed survival, fecundity, and behavioural data on 6119 individuals from six wild shorebird populations exhibiting flexible parental strategies. We show that these closely related populations express strikingly different ASRs, despite having similar ecologies and life histories, and that ASR variation is largely driven by sex differences in the apparent survival of juveniles. Furthermore, families in populations with biased ASRs were predominantly tended by a single parent, suggesting that parental cooperation breaks down with unbalanced sex ratios. Taken together, our results indicate that sex biases emerging during early life have profound consequences for social behaviour.

Cím:Persistence of an extreme male-biased adult sex ratio in a natural population of polyandrous bird / A. Kosztolányi, Z. Barta, C. Küpper, T. Székely
Dátum:2011
ISSN:1010-061X
Megjegyzések:In a number of insects, fishes and birds, the conventional sex roles are reversed: males are the main care provider, whereas females focus on matings. The reversal of typical sex roles is an evolutionary puzzle, because it challenges the foundations of sex roles, sexual selection and parental investment theory. Recent theoretical models predict that biased parental care may be a response to biased adult sex ratios (ASRs). However, estimating ASR is challenging in natural populations, because males and females often have different detectabilities. Here, we use demographic modelling with field data from 2101 individuals, including 579 molecularly sexed offspring, to provide evidence that ASR is strongly male biased in a polyandrous bird with male-biased care. The model predicts 6.1 times more adult males than females (ASR = 0.860, proportion of males) in the Kentish plover Charadrius alexandrinus. The extreme male bias is consistent between years and concordant with experimental results showing strongly biased mating opportunity towards females. Based on these results, we conjecture that parental sex-role reversal may occur in populations that exhibit extreme male-biased ASR.

Megjegyzések:Social behaviours are highly variable between species, populations and individuals. However, it is contentious whether behavioural variations are primarily moulded by the environment, caused by genetic differences, or a combination of both. Here we establish that biparental care, a complex social behaviour that involves rearing of young by both parents, differs between closely related populations, and then test two potential sources of variation in parental behaviour between populations: ambient environment and genetic differentiation. We use 2904 hours behavioural data from 10 geographically distinct Kentish (Charadrius alexandrinus) and snowy plover (C. nivosus) populations in America, Europe, the Middle East and North Africa to test these two sources of behavioural variation. We show that local ambient temperature has a significant influence on parental care: with extreme heat (above 40?C) total incubation (i.e. % of time the male or female incubated the nest) increased, and female share (% female share of incubation) decreased. By contrast, neither genetic differences between populations, nor geographic distances predicted total incubation or female's share of incubation. These results suggest that the local environment has a stronger influence on a social behaviour than genetic differentiation, at least between populations of closely related species.
