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.

Cím:Geographic variation in breeding system and environment predicts melanin-based plumage ornamentation of male and female Kentish plovers / Araceli Argüelles-Ticó, Clemens Küpper, Robert N. Kelsh, Kosztolányi András, Székely Tamás, René E. van Dijk

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:Climatic variation influences annual survival of an island-breeding tropical shorebird / Noémie Engel, Brett K. Sandercock, András Kosztolányi, Andreia Adrião, Alex Tavares, Romy Rice, Tamás Székely
Dátum:2024
ISSN:0908-8857
Megjegyzések:Global biodiversity loss is a major environmental concern. The wildlife on islands are particularly vulnerable to threats posed by alien predators, habitat loss and overexploitation. Effective conservation management of vulnerable species requires reliable information on vital population rates for all life stages and an understanding of key environmental drivers. However, demographic data are often not available for island populations before they decline or are extirpated. Here, we use Cormack?Jolly?Seber (CJS) models and 15 years of data for 1370 juveniles and 687 adults to estimate apparent survival for a genetically distinct resident population of Kentish plovers Charadrius alexandrinus on the island of Maio, Cabo Verde. We report two main findings. First, environmental conditions have a large effect on demographic performance since chicks that hatch during dry years experience a tenfold reduction in first-year survival compared to chicks that hatch during wet years. Second, female and male plovers in Maio are expected to live for 7.41 ? 0.69 (mean ? SE) years and 6.75 ? 0.64 years, respectively, due to relatively high annual survival among comparable-sized shorebirds. High adult survival thus could buffer the population against low reproductive success that this population has experienced over the last decade. Cabo Verde is typical of tropical islands with increased development that can impact native breeders and/or will accelerate habitat loss. Thus, more frequent droughts associated with climate change may exacerbate the prospects of native wildlife on many islands.

Cím:Sex Role Reversal and High Frequency of Social Polyandry in the Pheasant-Tailed Jacana (Hydrophasianus chirurgus) / Nolwenn Fresneau, Ya-Fu Lee, Wen-Chen Lee, András Kosztolányi, Tamás Székely, András Liker
Dátum:2021
ISSN:2296-701X
Megjegyzések:In a few species, males invest more than females in parental care while the females invest in mating competition and producing multiple broods for several mates. Species in the family Jacanidae are commonly used for studying this type of breeding system (called sex-role reversal), and previous studies found discrepancies and variation between species in the expected characteristics of reversed sex roles. Yet, a better understanding of sex role differences in breeding behavior in such species is crucial for disentangling possible evolutionary mechanisms leading to this peculiar breeding system. Sex-role reversal in the pheasant-tailed jacana Hydrophasianus chirurgus has been documented long time ago. Since the very early observation of this species, however, there was no attempt to provide a comprehensive and quantitative description of their breeding. This study aims to fill these knowledge gaps by investigating the sex role differences in the breeding behavior of pheasant-tailed jacanas, by observing and monitoring a breeding population in Taiwan. We focused on three main characteristics of sex-role reversal: (1) competition between females for access to males, such as agonistic and courtship behaviors, (2) polyandrous mating, and (3) male-only care. As expected, we found that females provide most of the territory defense toward conspecifics. Males also participated in agonistic behaviors, although less frequently than females. Furthermore, contrary to what was expected, we found that males spent more time than females on courtship behavior. Polyandrous females performed mating and laying sequentially with different mates but maintained the pair bonds simultaneously with multiple males. For the first time for the species, we could estimate that the average number of mates per female (i.e., degree of polyandry) was 2.4 and that at least 81.8% of the females in the population were polyandrous. Finally, our observations corroborated that brood care is predominantly provided by males, nevertheless females were also participating to some degree in brood attendance but never in direct care (i.e., brooding). This study highlights that some aspects of polyandrous breeding might deviate from stereotyped view on sex-role reversal, and stress the importance of further within species and comparative studies in order to fully understand the mechanisms leading to sex-role reversal.

Megjegyzések:When individuals breed more than once, parents are faced with the choice of whether to re-mate with their old partner or divorce and select a new mate. Evolutionary theory predicts that, following successful reproduction with a given partner, that partner should be retained for future reproduction. However, recent work in a polygamous bird, has instead indicated that successful parents divorced more often than failed breeders (Halimubieke et al. in Ecol Evol 9:10734-10745, 2019), because one parent can benefit by mating with a new partner and reproducing shortly after divorce. Here we investigate whether successful breeding predicts divorce using data from 14 well-monitored populations of plovers (Charadrius spp.). We show that successful nesting leads to divorce, whereas nest failure leads to retention of the mate for follow-up breeding. Plovers that divorced their partners and simultaneously deserted their broods produced more offspring within a season than parents that retained their mate. Our work provides a counterpoint to theoretical expectations that divorce is triggered by low reproductive success, and supports adaptive explanations of divorce as a strategy to improve individual reproductive success. In addition, we show that temperature may modulate these costs and benefits, and contribute to dynamic variation in patterns of divorce across plover breeding systems.

Cím:The impact of social structure on breeding strategies in an island bird / Grant C. McDonald, Noémie Engel, Sara S. Ratão, Tamás Székely, András Kosztolányi
Dátum:2020
ISSN:2045-2322
Megjegyzések:The social environment is a key factor determining fitness by influencing multiple stages of reproduction, including pair formation, mating behavior and parenting. However, the influence of social structure across different aspects of breeding is rarely examined simultaneously in wild populations. We therefore lack a consolidation of the mechanisms by which sociality impacts reproduction. Here we investigate the implications of the social environment before and during breeding on multiple stages of reproduction in an island population of the ground nesting shorebird, the Kentish plover (Charadrius alexandrinus). We utilise information on mating decisions, nest locations and nesting success across multiple years in combination with social network analysis. Sociality before breeding was connected with patterns of pair formation. In addition, site fidelity and personal breeding experience was associated with the spatial organisation of breeding pairs. Our results provide evidence that, while differential social interactions at localised scales influence patterns of reproductive pairing, site fidelity and personal breeding experience influence the structure of populations at the landscape scale. Our results underline the tight link between the social structure of populations and patterns of mating, while revealing that the relative influence of sociality, breeding experience and local ecology are dynamic across different facets of reproduction.

Dátum:2018
ISSN:1568-539X
Megjegyzések:Consistent individual behavioural differences ('animal personalities') are documented across a variety of animal taxa. Sexual selection, especially assortative mating has been suggested as a possible mechanism contributing to the maintenance of different personality types within populations but little is known about non-random pair-formation with respect to personality traits in unconstrained choice tests. We here tested whether female mating preferences were non-random with respect to male and female neophobia in zebra finches (Taeniopygia guttata), an important avian model of mate choice and animal personality research. Male and female neophobia was assessed by attaching novel objects to birds' feeders. Females' mating preferences were tested with randomly assigned, unfamiliar males in a four-way choice apparatus. Females associated most with males with neophobia scores similar to their own. These results provide evidence that mating preferences and personality traits can covary, supporting evolutionary scenarios of assortative mating contributing to the maintenance of personality traits.

Cím:The effects of adult sex ratio and density on parental care in Lethrus apterus (Coleoptera, Geotrupidae) / Rosa Márta E., Barta Zoltán, Fülöp Attila, Székely Tamás, Kosztolányi András
Dátum:2017
ISSN:0003-3472
Megjegyzések:Theoretical models suggest that adult sex ratio (ASR) and population density are expected to influence parental roles by reducing the mating opportunities of the commoner sex and by changing the intensity of sperm competition, although experimental evidence for these predictions is sparse. In biparental species with a high risk of extrapair paternity and consecutive egg laying over the breeding period, males are expected to reduce their parental investment and to spend more time on mate guarding if male density is high, to maximize their fitness. We conducted a field experiment to test this hypothesis in Lethrus apterus, a flightless biparental beetle species from the Geotrupidae family. Using seminatural enclosures, we assigned individuals to nine treatment groups differing in adult sex ratio (three levels) and individual density (three levels) using a full factorial experimental design. Nest attendance and parental provisioning (i.e. collecting and transporting leaves to the nest) were recorded as well as the number, size and sex ratio of the offspring. We found that as the level of male?male competition increased, generated either by the increased density of individuals or by the male-biased sex ratio, pairs showed higher nest attendance and collected fewer leaves. Male-biased groups also produced fewer offspring under high and low densities indicating a possible conflict of interest between the sexes over paternity and brood size. These results support the increased paternity assurance hypothesis under a high level of intrasexual competition.
