Cím:Tracking hybrid viability across life stages in a natural avian contact zone / Murielle Ålund, J. Carolina Segami Marzal, Yishu Zhu, P. Navaneeth Krishna Menon, William Jones, Anna Qvarnström

Megjegyzések:Hybrid inviability is an important post-zygotic reproductive barrier between species, but emerging signs of reduced viability can be difficult to study across the lifespan of natural hybrids. We use a combination of long-term monitoring, extra-pair paternity, and mitochondrial DNA identification in a natural hybrid zone of Ficedula flycatchers to detect emerging signs of intrinsic hybrid inviability across their entire lifespan. We evaluate possible evidence of Darwin's corollary to Haldane's rule, predicting asymmetries in inviability between hybrids resulting from reciprocal crosses, due to incompatible genetic factors with sex-specific inheritance patterns. We found higher hatching failure among mixed-species pairs, possibly indicating early developmental impairments associated with specific parental genetic combinations. Adult hybrids had a higher basal mortality rate than both parental species and different age-specific mortality trajectories. There were signs of differences in age-independent mortality rates between the reciprocal hybrid crosses: hybrids with a pied flycatcher mother experienced slightly increased mortality later in life. Using an exceptional dataset with many natural hybrids tracked across life stages, we provide evidence for several emerging signs of reduced hybrid viability. Incompatibilities between alleles located on autosomes and uniparentally inherited factors such as Z-linked and/or mitochondrial genes are strong candidates underlying intrinsic hybrid dysfunction in this system.

Cím:Sex differences in age-to-maturation relate to sexual selection and adult sex ratios in birds / Sergio Ancona, András Liker, M. Cristina Carmona-Isunza, Tamás Székely
Dátum:2020
ISSN:2056-3744
Megjegyzések:Maturation (the age when organisms are physiologically capable of breeding) is one of the major life history traits that have pervasive implications for reproductive strategies, fitness, and population growth. Sex differences in maturation are common in nature, although the causes of such differences are not understood. Fisher and Lack proposed that delayed maturation in males is expected when males are under intense sexual selection, but their proposition has never been tested across a wide range of taxa. By using phylogenetic comparative analyses and the most comprehensive dataset to date, including 201 species from 59 avian families, we show that intense sexual selection on males (as indicated by polygamous mating and male-skewed sexual size dimorphism) correlates with delayed maturation. We also show that the adult sex ratio (ASR), an indicator of the social environment, is associated with sex-specific maturation because in species with a female-skewed ASR, males experience later maturation. Phylogenetic path analyses suggest that adult sex ratio drives interspecific changes in the intensity of sexual selection which, in turn, influences maturation. These results are robust to alternative phylogenetic hypotheses and to potential life-history confounds, and they provide the first comprehensive support of Fisher's and Lack's propositions. Importantly, our work suggests that both social environment and mate competition influence the evolution of a major life history trait, maturation.

Dátum:2008
Megjegyzések:Natural-abundance isotopic substitution in isotopically prochiral groups of otherwise achiral molecules can provide stochastically formed enantiomeric excesses which exceed the sensitivity threshold of sensitive asymmetric autocatalytic (Soai-type) reactions. This kind of induction of chirality should be taken into consideration in in vitro model experiments and offer a new kind of entry into primary prebiotic or early biotic enantioselection in the earliest stages of molecular evolution.

Cím:Flow Intermittence Drives the Benthic Algal Composition, Biodiversity and Diatom-Based Quality of Small Hilly Streams in the Pannonian Ecoregion, Hungary / Viktória B-Béres, Zsuzsanna Kókai, Gábor Várbíró, Gulperizat Mustazhapova, Zoltán Csabai, Bálint Pernecker, Gábor Borics, István Bácsi, Pál Boda

Megjegyzések:Climate change is putting increasing pressure on flowing waters. Drastic water level fluctuations in rivers or drying up of small and medium-sized streams all contribute to the biodiversity crisis threatening freshwater ecosystems. Benthic diatoms are important elements of biofilm in small streams. However, knowledge on the relationship between benthic diatoms and flow intermittence is incomplete, especially in regions recently impacted by recurrent drying. Thus, we investigated benthic diatom flora of small intermittent, hilly streams in the warm temperate region of Europe (the Pannonian Ecoregion). Our hypotheses were addressed to compositional changes, biodiversity loss and diatom-based ecological assessment. The results revealed clear flow intermittence- induced differences in taxa and trait composition of diatoms. Altogether six species for the dry phase and three species in the aquatic phase were identified as indicative ones by using indicator value analyses. In contrast to water regime induced changes in assemblages, there was a seasonal overlap in taxa and trait composition. During the study period, the drying up of streams did not result in significant biodiversity loss either at taxa or trait levels. Functional dispersion, however, reduced significantly by summer. Overall, neither the hydrological regime nor seasonal changes had a significant effect on diatom-based quality indices, except for the Rott trophic index (TID index). The TID index values were significantly lower in dry phases than in aquatic ones. These results suggested that the drying up of streams has a very complex influence on benthic diatoms. It seems that taxonomical and functional redundancy can reduce the negative impact of short-time flow intermittence on assemblages. As a practical benefit, the results are the first to support the use of diatom-based quality indices in the assessment of flow intermittence in the temperate region.

Cím:Incipient sympatric speciation via host race formation in Phengaris arion (Lepidoptera: Lycaenidae) / Judit Bereczki, Szilárd Póliska, Alex Váradi, János P. Tóth
Dátum:2019
ISSN:1439-6092
Megjegyzések:The plausibility of sympatric speciation is still debated despite increasing evidence, such as host races in insects. This speciation process may be occurring in the case of the two phenological forms of the obligatorily myrmecophilous Phengaris arion. The main goal of our research was to study the nature and causes of difference between these forms focusing primarily on the incipient speciation via host races. Molecular analyses based on highly variable microsatellites together with Wolbachia screening, male genitalia morphometrics and host ant studies were carried out on four syntopic sample pairs. Our results show that the two phenological forms of P. arion may meet the criteria for host plant races. They coexist in sympatry in certain parts of the species range which is allowed by the adaptation to the distinct phenology of the host plants. Negative selection acts against the intermediate individuals which are on the wing in the inappropriate time frame. Thus, disruptive selection affects and produces bimodal distributions of phenotypes. However, the phenology of food plants is not entirely distinct and fluctuates year by year. Therefore, the two forms can exchange genes occasionally depending on the length of the time slot when they can meet with each other. Consequently, the reproductive isolation could not be completed and the existence of the two arion forms may represent only an incipient stage of sympatric speciation. It is also clear that Wolbachia is likely not a driver of sympatric speciation in this case.

Cím:Controversial patterns of Wolbachia infestation in the social parasitic Maculinea butterflies (Lepidoptera: Lycaenidae) / Judit Bereczki, Rita Rácz, Zoltán Varga, János P. Tóth
Dátum:2015
ISSN:1439-6092 1618-1077
Megjegyzések:Wolbachia is a common group of intracellular bacteria found in arthropods and filarial nematodes. Since the past decade, they have attracted considerable interest owing to their various effects on hosts, which range from reproductive manipulation to mutualism. Moreover, they can influence the mitochondrial DNA pattern which do not reflect the real evolutionary history of the target species and may be incongruent with nuclear data. Previously, Wolbachia-manipulated mitochondrial DNA (mtDNA) patterns, namely mito-nuclear discordance and deep mitochondrial splits associated with specific Wolbachia infections, have been also discovered in the genus Maculinea. Here, we present a comprehensive study on Wolbachia infestation and the genetic diversity of all Maculinea species int he Carpathian Basin. The prevalence and the pattern of the infestation highly differ among Maculinea species. Maculinea alcon and Maculinea arion are infected in 100%, each of these species with a single strain, but the infection level of Maculinea nausithous and Maculinea teleius is much lower, additionaly, they are infected with multiple strains. The genetic diversity of Maculinea species proved to be generally low, only M. nausithous showed geographic pattern based on mitochondrial sequences and allozymes. In contrast with the previous studies, we could not detect mito-nuclear discordance or find evidence for Wolbachia-induced selective sweep. Based on our results, we cannot hold only Wolbachia responsible for the restricted genetic diversity of Maculinea in the Carpathian Basin. Probably several factors shape together the level and pattern of genetic variability in Maculinea butterflies.

Megjegyzések:Himantoglossum adriaticum H. Baumann is a long-lived perennial orchid with an adriato-mediterranean distribution. The species-level separation of this species from the more geographically widespread H. hircinum has only recently been confirmed via a combination of molecular and morphometric techniques, which are further developed here. To provide a comprehensive overview of its autecology we integrated previously published information with extensive unpublished data derived mainly from populations in the Keszthely Hills of Hungary. In this paper we assess the distribution, habitat preferences, life history and seed germination (ex situ and in situ) of H. adriaticum, with special emphasis on its reproductive biology.

Cím:Changing Migratory Behaviors and Climatic Responsiveness in Birds / Bókony Veronika, Barta Zoltán, Végvári Zsolt
Dátum:2019
ISSN:2296-701X
Megjegyzések:Change of avian migratory behavior is one of the best-studied phenomena presumably associated with contemporary climate change, yet to what degree these behavioral changes represent responses to climate warming is still controversial. We investigated interspecific variation in migratory behavior over three decades at a Central-European site, testing whether the type and extent of behavioral change are predicted by species' responsiveness to short-term variation in large-scale climatic indices. We found that species with earlier arrivals at the breeding grounds after winters with higher North-Atlantic Oscillation indices were more likely to overwinter at the study site. This behavior was more frequent in the second half than in the first half of the study, although the extent of this change was not predicted quantitatively by short-term climatic responsiveness. Overwintering was more prevalent in short-distance migrants with more complex diets and larger population sizes. Furthermore, species arriving earlier after summers with higher Sahel rainfall indices increasingly advanced their first arrival date, whereas species that do not molt in the pre-breeding season increased their frequency of overwintering in more recent years. Our results demonstrate that interspecific variation in short-term climatic responsiveness predicts long-term changes in migratory behaviors, supporting that the latter are responses to climate change. Furthermore, the type of response (advancing arrivals or overwintering near the breeding grounds) depends on life history. Finally, we found that overwintering behavior during the study period predicted subsequent trends in population size, suggesting that information on temporal changes in migratory strategy may help conservation planning and risk assessment.

Cím:Comparative influence of Odh and Adh loci on alcohol tolerance in Drosophila melanogaster / Katalin Bokor, Katalin Pecsenye
Dátum:1998
Megjegyzések:The effect of ethanol on larva-to-pupa and larva-to-adult survival was compared in ten laboratory strains of Drosophila melanogaster. The strains had five different allele combinations at the Adh and Odh loci. Two parallel strains of the five two-locus genotypes were isolated from different isofemale lines, and so they had different genetic backgrounds. Second instar larvae of all ten strains were exposed to different ethanol treatments and larva-to-pupa and larva-to-adult survival components were estimated. The strains with different genetic background but identical genotypic combinations at the Adh and Odh loci had different initial survival rates but they exhibited similar tolerance to ethanol. Ethanol tolerance appeared to depend predominantly on the Odh locus. The two Adh genotypes did not show significantly different ethanol tolerance. In contrast, the three Odh genotypes tolerated exogenous ethanol differently: O Fdh homozygotes had the highest tolerance to ethanol in both the larval and pupal stages.

Megjegyzések:Background: Land-use is a major driver of changes in biodiversity worldwide, but studies have overwhelmingly focused on above-ground taxa: the efects on soil biodiversity are less well known, despite the importance of soil organisms in ecosystem functioning. We modelled data from a global biodiversity database to compare how the abundance of soil-dwelling and above-ground organisms responded to land use and soil properties. Results: We found that land use afects overall abundance diferently in soil and above-ground assemblages. The abundance of soil organisms was markedly lower in cropland and plantation habitats than in primary vegetation and pasture. Soil properties infuenced the abundance of soil biota in ways that difered among land uses, suggesting they shape both abundance and its response to land use. Conclusions: Our results caution against assuming models or indicators derived from above-ground data can apply to soil assemblages and highlight the potential value of incorporating soil properties into biodiversity models.
