In a few butterflies, large external mate‐guarding devices, that is, sphragides, occur. Gór et al. ( Behaviour , 160, 2023 and 515−557) found conspicuously large size and morphological variation of mate‐guarding devices within a single population of the potentially polyandrous Clouded Apollo ( Parnassius mnemosyne , L.) butterfly. They termed the externally visible male‐produced devices as Copulatory opening APpendices (CAP) consisting of small devices, termed small CAPs and the much larger shield (i.e. sphragis). Our aim was to reveal CAP replacement dynamics within females during their lifetime and to understand how male investment into small CAPs or shields was (i) related to CAP persistence on the female, that is securing paternity, (ii) associated with female quality, measured as size and (iii) with actual adult sex ratio. We investigated a univoltine Clouded Apollo population to estimate CAP replacement risks, using multistate survival models, in an extensive observational study through 6 years based on mark‐recapture. Shields were the most frequent mate‐guarding devices and were more persistent than small CAPs, often lasting for life, excluding future matings. Thus, most females bearing a shield were deprived of postcopulatory female choice, and the genetic variance in their offspring could be reduced compared to those bearing small CAPs, thus mating more often. The ratio of shields to all CAPs gradually decreased towards the end of the flight period. Males were more prone to produce a shield when mating females with wider thoraces and when the ratio of males (i.e. competition) was higher in the population. To our best knowledge, this is the first quantitative study to investigate potential factors on which male investment in mate‐guarding devices may depend, and how the variation in these devices impacts CAP persistence on females.}, year = {2023}, eissn = {2045-7758}, orcid-numbers = {Vajna, Flóra/0000-0003-4451-855X; Kis, János/0000-0001-9354-1292} } @article{MTMT:34104589, title = {First steps of pollinator-promoting interventions in Eastern European urban areas – positive outcomes, challenges, and recommendations}, url = {https://m2.mtmt.hu/api/publication/34104589}, author = {Süle, Gabriella and Kovács-Hostyánszki, Anikó and Sárospataki, Miklós György and Kelemen, Tünde Ilona and Halassy, Gabriella and Horváth, Anna and Demeter, Imre and Báldi, András and Szigeti, Viktor}, doi = {10.1007/s11252-023-01420-1}, journal-iso = {URBAN ECOSYST}, journal = {URBAN ECOSYSTEMS}, volume = {26}, unique-id = {34104589}, issn = {1083-8155}, abstract = {Urbanisation has a strong role in pollinator decline, while properly managed green spaces could promote pollinators – especially bees and butterflies – by providing foraging and nesting habitats in cities. In public spaces, several opportunities exist to help pollinators including rare mowing, flower strip sowing, and bee hotel establishment. However, pollinator-promoting interventions are almost lacking and still understudied in Eastern Europe. We aimed to investigate the impact of rare mowing and annual flower-sowing interventions on pollinators, floral resources, and vegetation attributes in three case studies within Hungary. We compared treatment (extensively mown or sown) and control (intensively mown) site pairs during five sampling occasions within a season. We found positive, but due to the severe drought and management inaccuracies relatively minor effect of both interventions. The extensively mown sites presented higher and greener vegetation with more flowers and pollinators. The sown flower patches provided floral resources and supported the pollinators in the second half of the season, while they were scarcely visited in spring and early summer due to the annual soil scarification and re-sowing. Although the two types of interventions could complement each other during the season, there is room for further improvements. To reach resilient urban ecosystems against climate and environmental changes, we recommend using primarily native and mostly perennial seeds, combining intervention types, planning for the long-term, and avoiding management inaccuracies (e.g. unplanned mowing).

In contrast, we investigated alternative mate-guarding devices in detail of a sphragis-bearing butterfly. We conducted a six-year observational field study in a Clouded Apollo Parnassius mnemosyne population. Inspecting 492 females, we identified 3 different devices, filament, stopple and shield (i.e., sphragis) increasing in size and structure complexity, implying differential male investment and effectiveness in securing paternity. Shield dimensions, colour and all devices’ shapes varied considerably. Shields were far more frequent than other devices. Some devices were lost, and a few were video-recorded when removed by males, showing the role of different parts of male external genitalia.

Gaillardia aristata (great blanketflower) is planted worldwide and its escape has been reported in several European countries without ecological impact assessment on the invasive potential. As there is a markedly spreading population with invasive behaviour in Hungary, we aimed to reveal the distribution, impacts and traits of G. aristata . We gathered occurrence data outside the gardens in Hungary, based on literature, unpublished observations by experts and our own records. We investigated the impacts of an extended population, where the species invaded sandy old-fields within a 25 km 2 area. Here, we compared the species richness, diversity, community composition and height of invaded and uninvaded vegetation. Furthermore, we evaluated the traits potentially associated with the invasiveness of G. aristata in comparison with other herbaceous invasive species in the region. We found that G. aristata occurred mostly by casual escapes, but naturalised and invasive populations were also detected in considerable numbers. G. aristata usually appeared close to gardens and ruderal habitats, but also in semi-natural and natural grasslands and tended to spread better in sandy soils. We found lower plant species richness and Shannon diversity in the invaded sites and the invasion of G. aristata significantly influenced the composition of the plant community. The trait analyses revealed that the invasive potential of G. aristata is backed by a wide germination niche breadth, extremely long flowering period, small shoot-root ratio (large absorption and gripping surface), large seeds (longer persistence) and dispersal by epizoochory of grazing livestock (mostly by sheep), probably helping the species’ survival and spreading in the disturbed, species-poor, sandy, open habitats. These functional traits, as well as the ornamental utilisation, may act together with the aridisation of the climate and the changing land-use practices (e.g. abandoned, disturbed sites) in the success of G. aristata . We raise awareness of the rapid transition of G. aristata from ornamental plant to casual alien and then to invasive species in certain environmental conditions (i.e. sandy soils, species-poor communities, human disturbances), although it seems to be not a strong ecosystem transformer so far. Nonetheless, banning it from seed mixtures, developing eradication strategy and long-term monitoring of this species would be important to halt its spreading in time.}, year = {2023}, eissn = {1314-2488}, pages = {43-69}, orcid-numbers = {Fenesi, Annamária/0000-0001-6596-9857} } @article{MTMT:33712342, title = {Trait‐based effects of plant invasion on floral resources, hoverflies and bees}, url = {https://m2.mtmt.hu/api/publication/33712342}, author = {Szigeti, Viktor and Fenesi, Annamária and Botta-Dukát, Zoltán and Kuhlmann, Michael and Potts, Simon G. and Roberts, Stuart and Soltész, Zoltán and Török, Edina and Kovács-Hostyánszki, Anikó}, doi = {10.1111/icad.12640}, journal-iso = {INSECT CONSERV DIVER}, journal = {INSECT CONSERVATION AND DIVERSITY}, volume = {16}, unique-id = {33712342}, issn = {1752-458X}, year = {2023}, eissn = {1752-4598}, pages = {483-496}, orcid-numbers = {Fenesi, Annamária/0000-0001-6596-9857; Botta-Dukát, Zoltán/0000-0002-9544-3474; Török, Edina/0000-0001-5982-7078} } @article{MTMT:33678113, title = {No consistencies in abundance-impact relationships across herbaceous invasive species and ecological impact metrics}, url = {https://m2.mtmt.hu/api/publication/33678113}, author = {Fenesi, Annamária and Botta-Dukát, Zoltán and Miholcsa, Zsombor and Szigeti, Viktor and Molnár, Csaba and Sándor, Dorottya and Szabó, Anna and Kuhn, Thomas and Kovács-Hostyánszki, Anikó}, doi = {10.1111/1365-2745.14085}, journal-iso = {J ECOL}, journal = {JOURNAL OF ECOLOGY}, volume = {111}, unique-id = {33678113}, issn = {0022-0477}, abstract = {Abstract 1. The general shape (from linear to complex curve), direction (negative, positive), and strength (steepness of the slope) of abundance-impact relationships for different impact metrics are poorly known, despite their importance in understanding and predicting ecological repercussions of invasive species. It is also an open question how the functional traits of invasive species may influence the abundance-impact relationship. 2. We studied 11 widespread herbaceous invasive alien species of East-Central Europe and their 16 impact metrics (resident plant communities’ ecological characteristics, trait composition, functional diversity, and soil parameters) by sampling invaded and similar, uninvaded sites (space-for-time substitution method). Our aim was to (1) investigate the detailed ecological impacts of invasive plants on native plant communities; (2) explore the type of cover-impact relationships across impact metrics and their consistency across species; (3) study whether the cover-impact relationship depends on functional traits of invasive species. 3. When considering all invasive species together, we found that invaded plant communities were less species-rich and less functionally even but showed higher values of Rao’s Q diversity index, and higher nitrogen, phosphorus, and organic carbon soil nutrient content compared to uninvaded communities. However, the species-wise analyses revealed strikingly different impacts among the 11 invasive species and also among impact metrics. 4. Regarding the type of cover-impact relationships, we found no consistencies across invasive species and impact metrics. Still, non-linear relationships prevailed when species were analysed together and linear relationships when species were studied individually. The functional traits of the invasive species explained only a small part of this response heterogeneity; mostly the small-seeded perennial invasive species affected the cover-species richness relationship. Synthesis: Herbaceous invasive plant species have a cover-dependent impact on resident plant communities, but there are no consistent patterns across impact metrics and invasive species. Specific traits or trait-syndrome of invasive species may affect the heterogeneity of cover-impact relationships, but that would need further study. We highlighted the importance of impact assessments involving invasive species’ abundance to unmask cryptic impacts for species that show contrasting effects along an abundance gradient.}, keywords = {DIVERSITY; Hungary; Romania; Species richness; plant invasion; Alien plants; functional traits; plant cover}, year = {2023}, eissn = {1365-2745}, pages = {1120-1138}, orcid-numbers = {Fenesi, Annamária/0000-0001-6596-9857; Botta-Dukát, Zoltán/0000-0002-9544-3474} } @article{MTMT:33548066, title = {Phenotypic senescence in a natural insect population}, url = {https://m2.mtmt.hu/api/publication/33548066}, author = {Pásztor, Katalin and Kőrösi, Ádám and Gór, Ádám and Szigeti, Viktor and Vajna, Flóra and Kis, János}, doi = {10.1002/ece3.9668}, journal-iso = {ECOL EVOL}, journal = {ECOLOGY AND EVOLUTION}, volume = {12}, unique-id = {33548066}, issn = {2045-7758}, abstract = {Senescence seems to be universal in living organisms and plays a major role in life-history strategies.

We aimed (i) to investigate how body mass and thorax width change with age in a natural population of the univoltine Clouded Apollo butterfly (Parnassius mnemosyne, Lepidoptera: Papilionidae) and (ii) to assess the relationship of this change with sex and wing length. We studied a population between 2014 and 2020 using mark-recapture during the whole flight period each year. Repeated measurements of body mass and thorax width and single measurements of wing length were performed on marked individuals. We analyzed body mass and thorax width change with age (days since marking), wing length, and the date of the first capture. Both body mass and thorax width declined nonlinearly with age. Individuals appearing earlier in the flight period had significantly higher initial body mass and thorax width and their body mass declined faster than later ones. Initial body sizes of females were higher, but males' body sizes decreased slower. Initial thorax width showed higher annual variation than body mass. To our best knowledge, this is the first study that revealed phenotypic senescence in a natural butterfly population, using in vivo measurements.

A kutatás fókuszában a négy ágazat mézelő inváziós növényfajokkal kapcsolatos konfliktusos pontjainak és együttműködési lehetőségeinek feltárása volt. Az interjú összefoglalókat kvalitatív elemzésnek vetettük alá. Eredményeink azt mutatták, hogy a vizsgált fajok elterjedését és trendjeit az ágazatok részben eltérően ítélik meg. A vizsgált fajok közül a legmarkánsabb ellentét egyértelműen az akác kapcsán érzékelhető az ágazatok között. A természetvédelmi ágazat számára a fehér akác az egyik legártalmasabb özönfaj, a méhészek legfontosabb mézelő növényfaja, az erdőgazdálkodók számára értékes faanyagot jelent, inváziós jellegét egyes szakemberek nem ismerik el. A közönséges selyemkóró, valamint az inváziós aranyvessző fajok tömeges jelenléte a természetvédelem és a mezőgazdaság számára egyaránt komoly költségeket jelent a visszaszorítás szükségessége és a mezőgazdálkodók számára a támogatásokból való kizárás lehetősége miatt is. A méhészek számára a selyemkóró néhány évtizeddel ezelőtti jelentőségéből folyamatosan veszít, köszönhetően annak, hogy a klímaváltozás kapcsán bekövetkező szárazodás hatására nektár produkciós képessége jelentősen lecsökkent. Az aranyvessző jelentősége a méhcsaládok betelelésében rejlik, ugyanis kulcsfontosságú a raktáraik feltöltése természetes virágporral, ez pedig az utolsó jelentős virágzású méhlegelő az évben. Az ágazati szakértők visszajelzései alapján a vizsgált fajokat érintő legtöbb jogszabály és támogatás a visszaszorítást hivatottak segíteni. A támogatások között azonban akad olyan, amely inkább a terjedést segíti elő. Az érintett ágazatok eltérő érdekeikből adódóan különféleképpen értékelik az inváziós fajokat, azonban előremutató, hogy együttműködésekre is van hajlandóság és példa.
