Cím:Phylogenetic patterns of a nightingale population in a contact zone of Luscinia megarhynchos and L. luscinia in Hungary / Zoltán Ács, Dávid Kováts
Dátum:2013
ISSN:1584-9074 1843-5629
Megjegyzések:Phylogenetic patterns of two closely related nightingale species the Luscinia megarhynchos and the L.luscinia were investigated in north-eastern part of Hungary. The mitochondrial cytochrome-c oxidase subunitI (COI) gene amplified by polymerase chain reaction (PCR) and sequenced directly to set up theirphylogenetic relationships. In eastern Hungary (Szatmár-Beregi Landscape Protected Area, Vámosatya, Bockerek forest 48(degree)11'N, 22(degree)23'E), a new haplotype of L. luscinia is discovered. Based on our molecular result, however, no individual of L. luscinia was found in the Upper-Tisza Region (especially between Tiszabercel and Tiszatelek), where its old breeding stands formerly occurred. It suggests its population might extinctfrom this region, or partially shifted to undisturbed territories, probably due to ecological impoverishment offloodplain forest associations. Furthermore, it appears that range expansion of L. megarhynchos increased inthose of fragmented habitats.

Cím:The analysis of common cuckoo's egg shape in relation to its hosts' in two geographically distant areas / Miklós Bán, Zoltán Barta, Antonio R. Munoz, Fugo Takasu, Hiroshi Nakamura, Csaba Moskát
Dátum:2011
Megjegyzések:Evolutionary adaptations are required by common cuckoos Cuculus canorus to match host eggs. Hosts may discriminate against alien eggs; hence, accurate matching of the parasite egg to the hosts' is essential. Egg shape is the least-studied component of egg mimicry, and it may also have other functions: an optimal egg shape is necessary for effective incubation. For this reason, cuckoo eggs may show a wide range of variations in shape to a set of host species. Here, we compare cuckoo and host eggs by using egg shape parameters in two distant areas: from the nests of great reed warblers Acrocephalus arundinaceus, robins Erithacus rubecula and marsh warblers Acrocephalus palustris in Hungary, and oriental reed warblers Acrocephalus orientalis, bull-headed shrikes Lanius bucephalus and black-faced buntings Emberiza spodocephala from Japan. Our results suggest the lack of evolutionary adaptation of different cuckoo gentes to their corresponding hosts in terms of egg shape. However, our analyses revealed that cuckoo eggs showed a geographical difference in egg shape.

Cím:Exploration of a hybrid zone between two toad species in Central Europe`s Carpathian region with a new molecular marker / Zoltán Gál, Tibor Kovács, János Ujszegi, Brandon P. Anthony, Balázs Vági Orsolya I.Hoffmann
Dátum:2024
ISSN:1584-9074 1843-5629
Megjegyzések:Analyzing hybrid zones allows insight into interactions between previously isolated lineages. The distributions of firebellied toads (Bombina bombina) and yellow-bellied toads (B. variegata) meet in the Carpathian Basin. We aimed to explore the genetic composition of a transient zone between the two sister species along a transect in the Carpathian foothill region. We collected 230 specimens from 21 locations and sampled them using buccal swabs. We used mitochondrial markers and designed a novel test based on the restriction of the nuclear Ncx-1 gene to distinguish between the two species and determine hybrid individuals. According to our results, the complete Börzsöny Hills and many locations in Krupinská Planina were colonized by B. bombina, including typical B. variegata habitats at higher elevations. However, in Krupinská Planina, the most remote sites still harbor B. variegata populations, often mixed with hybrid individuals. This pattern may indicate the northward and altitudinal range expansion of B. bombina. Our results warrant enhanced attention to hybrid zones, where introgression and other changes in the populations` genetic composition may reflect recent rapid environmental alterations.

Cím:The effect of prey availability on spider assemblages on European black pine (Pinus nigra) bark: spatial patterns and guild structure / Roland Horváth, Szabolcs Lengyel, Csaba Szinetár, László Jakab
Dátum:2005
ISSN:0008-4301
Megjegyzések:Both habitat structural complexity and prey availability can influence the density and diversity of spider assemblages. We studied whether prey availability affects spider assemblages living on the bark of European black pine (Pinus nigra Arnold) in six localities in Hungary. We found both positive and negative relationships between spider and prey assemblages in a sample of 1290 spiders and 24 186 potential prey when among-locality variation in spider assemblages was controlled for. Species richness, number of individuals, and diversity of spiders increased with either the number of prey taxa or the number of prey individuals in a forest in western Hungary. Spider species richness and number of individuals increased with prey diversity but decreased with number of prey taxa in moderately air-polluted urban localities. There was a negative relationship between number of spider individuals and number of prey individuals in a heavily polluted urban locality. Numbers of nocturnal hunters but not diurnal hunters or web-builders increased with the number of their respective prey in the forest in western Hungary and in the moderately air-polluted urban localities. The number of exclusive bark-dwelling spiders increased with the number of prey individuals in forests in eastern Hungary and decreased with the number of prey individuals in the polluted urban locality. We suggest that patterns of spider assemblages can be influenced by prey availability and that other factors (e.g., habitat structural diversity and air pollution) also need to be considered in explaining these patterns
La complexité de la structure de l'habitat et la disponibilité des proies peuvent toutes deux influencer la densité et la diversité des peuplements d'araignées. Nous avons examiné comment la disponibilité des proies affecte les peuplements d'araignées vivant sur l'écorce du pin noir (Pinus nigra Arnold) ℓa six sites de Hongrie. Il existe des relations positives et négatives entre les peuplements d'araignées et de proies dans un échantillon de 1290 araignées et de 24 186 proies potentielles, une fois que l'on tient compte de la variation des peuplements d'araignées entre les sites. Dans une for©et de l'ouest de la Hongrie, la richesse en espℓeces, le nombre d'individus et la diversité des araignées augmentent en fonction ou du nombre de taxons de proies ou du nombre de proies individuelles. Dans les sites urbains ℓa pollution atmosphérique modérée, la richesse en espℓeces et le nombre d'individus augmentent chez les araignées en fonction de la diversité des proies, mais diminuent en fonction du nombre de taxons de proies. Il existe une relation négative entre le nombre d'individus et le nombre de proies individuelles dans le site urbain fortement pollué. Les araignées chasseresses nocturnes, mais non les chasseresses diurnes, ni les constructrices de toiles, augmentent leur densité en fonction de leurs proies respectives dans la for©et de l'ouest de la Hongrie et dans les sites ℓa pollution atmosphérique modérée. Le nombre d'araignées qui vivent exclusivement sur les écorces augmente en fonction du nombre de proies individuelles dans les for©ets de l'est de la Hongrie et décro©it en fonction du nombre de proies individuelles dans le site urbain pollué. Nous croyons que la structure des peuplements d'araignées peut ©etre influencée par la disponibilité des proies, mais qu'il faut aussi tenir compte d'autres facteurs explicatifs, tels que la diversité structurale de l'habitat et la pollution atmosphérique.

Cím:Behavioural repertoire and the effect of male removal in a geotrupid beetle with parental care / Kiss, J., Rosa, M. E., Rácz, R., Kosztolányi, A., Barta, Z.
Dátum:2023
ISSN:0952-8369
Megjegyzések:Although biparental care is thought to be rare among insects, it has evolved independently numerous times resulting in diverse forms and varying levels of parental involvement. Several theoretical studies address potential factors promoting biparental care in beetles; however, empirical studies target principally only species of Scarabaeidae and Silphidae families. Here, we investigated the behavioural repertoire of the breeding pairs in two natural populations of a geotrupid beetle Lethrus apterus with parental care. Changes in female care as a response to the male`s absence were also investigated by experimentally removing males from pairs. We found that males spend the majority of their time at the nest entrance, while females leave their nest and collect leaves at a significantly higher rate than males. We also showed that males often desert their nests and were usually replaced by new males in a short time. The desertion of males, however, does not seem to influence females` behaviour. These findings indicate that L. apterus may have a dynamic mating system with typically short-term mate fidelity. Furthermore, our results have advanced our understanding of parental roles and nesting behaviour and contributed to the description of the distinct roles of parents in different phases of nesting events in L. apterus beetles.

Cím:Host-symbiont relationship and abundance of feather mites in relation to age and body condition of the barn swallow (Hirundo rustica) : an experimental study / Péter László Pap, Jácint Tökölyi, Tibor Szép
Dátum:2005
Megjegyzések:We analyzed the host-symbiont relationship and factors determining the abundance of feather mites among individual barn swallows (Hirundo rustica L., 1758) in two different host populations during the breeding season and postbreeding period. By experimentally removing the feather mites from the flight feathers of the birds with an insecticide, we showed that these symbiotic organisms have neither harmful nor beneficial effects on the fitness of the host, supporting the view that mites are commensals. This was indicated by the lack of any difference in the change in wing-feather length, tail-feather length, fluctuating asymmetry in tail-feather length, breeding performance, and survival of the birds between the fumigated and control groups 1 year after the experiment. During the postbreeding period juveniles harbored fewer mites than adults and the difference was also significant between the 1-year-old birds and those over 1 year old in the breeding population. The number of mites did not change after the second year of life of the birds. We hypothesize that the difference in abundance of mites between the age classes can be explained by the low reproductive potential of the mites, which are not able to populate the exploitable space until the second year of life of the host. Alternatively, young birds might provide fewer resources than old birds. The significant negative association between the number of mites and the laying date of female barn swallows seems to support the conclusion that the abundance of mites is condition-dependent. Because there was no relationship between other condition indices for males and females and number of mites, further research is needed to confirm this conclusion.

Cím:Diet quality affects postnuptial molting and feather quality of the house sparrow (Passer domesticus) : interaction with humoral immune function? / Péter László Pap, Csongor István Vágási, Gábor Árpád Czirják, Zoltán Barta
Dátum:2008
ISSN:0008-4301
Megjegyzések:We investigated the effects of nutritional limitation, humoral immune activation, and their interaction on postnuptial molting of aviary-kept house sparrows (Passer domesticus (L., 1758. In a 2*2 experimental design, we measured the progress of molting and the quality of feathers produced during molting by house sparrow exposed to different diet qualities (high and low9 and humoral immune activation with sheep red blood cells (SRBC). Food quality, but not the activation of humoral immunity, affected significantly the body mass and the process of molting.Sparrows feeding on low-quality food had decreased body mass and longer molts than the high-quality group.Low-quality food, but not the activation of humoral immunity, reduced significantly the length and mass (i.e.,the quality) of primaries grown during molting. birds responded significantly to injection with SRBC compared with the control group, but the immune response was similar between nutritional groups. The absence of a negative effect of humoral immunity on molting in house sparrows might be related to the low energy and nutritional requirements of mounting and maintaining a humoral immune response.

Cím:Size-dependent investment in tusk length, testis size and sperm length in a biparental geotrupid beetle / M. E. Rosa, J. Kiss, Z. Barta, A. Kosztolányi
Dátum:2019
ISSN:0952-8369
Megjegyzések:Males of extreme small or large sizes often experience different levels of pre- and postcopulatory sexual selection that result in alternative ways to gain fertilization success. Here, we investigated such alternative mating tactics in Lethrus apterus, a biparental geotrupid beetle species with noticeable intermale size variation by comparing tusk (mandibular process) length, testis size and sperm length between large and small males. Firstly, we demonstrated evidence for male polymorphism as extremely large males had longer tusks relative to their body size than extremely small individuals. Secondly, large males had bigger testes than small males throughout the breeding season, however, a significant decrease was observed overtime in large but not in small individuals. Thirdly, sperm length did not differ between the two size categories. Although these results do not explain how the observed large body size variation can be maintained in L. apterus, the non allo-metric relationship found between tusk length and body size and the lower decrease in testis size over the breeding season in case of small individuals might refer to the presence of alternative mating tactics in this species.

Cím:Flower visiting preferences of bumblebees (Apidae: Bombus spp.) in grasslands of the Velyka Dobron' Game Reserve (Transcarpathia, Ukraine) / Szabolcs Szanyi, Anikó Kovács-Hostyánszki, Zoltán Varga, Antal Nagy
Dátum:2020
ISSN:1584-9074 1843-5629
Megjegyzések:Frequency of flower visitations of six bumble bee (Bombus) species was surveyed in Transcarpathia (Ukraine). In four areas of the Game Reserve of Nagydobrony and surroundings five-five sampling quadrates were designated. The frequency of flower visitations of 16 dominant plant species (7 spp. in Fabaceae, 3 spp. in Asteraceae, 3 spp. in Lamiaceae, and 3 species from other families) were registered in four repetitions in mid-summer. The most frequent large bumble bee species, B. terrestris, exploited the widest spectrum of flower sources, with insignificant preference for Lotus corniculatus, Prunella vulgaris and Lythrum salicaria. The flower visitation of B. lapidarius was characterised by the high frequency of L. salicaria and Medicago sativa. The small bumble bee species, B. pascuorum, B. sylvarum and B. humilis, also showed significantly different preferences. Generally, the three most frequently visited plant species belonged to Fabaceae, followed by Symphytum officinale (Boraginaceae). We did not observe any significant difference between large vs. small bumble bees, either concerning the nectar source families or in length and shape of the visited flower corollas. Significant influence of flower colours, both as they are experienced by bumble bees (blue, bluish-green) and according to the visible colours (purple), was found on the flower visitation by nearly all bumble bee species. Since practically all species have shown somewhat different preferences for nectar sources, we could not observe any genuine communities of bumble bees; however, accidental feeding assemblages can exist based on high preferences of species in Fabaceae.
