Summary 1. The view of post‐mining sites is rapidly changing among ecologists and conservationists, as sensitive restoration using spontaneous succession may turn such into biodiversity refuges in human‐exploited regions. However, technical reclamation, consisting covering the by topsoil, sowing fast‐growing herb mixtures planting trees, still commonly adopted. Until now, no multi‐taxa study has compared technically reclaimed left with succession. 2. We sampled communities vascular plants 10...

The nectarivory of sunbirds in the Old World and hummingbirds New evolved independently. While both groups are specialised their feeding apparatuses, moreover famous for adaptations to sustained hovering flight. Recently, an example a pollination system invasive plant Nicotiana glauca has been used show that less adapted also frequently able hover. Nevertheless, question remained why plants bird do not occur outside World. In this paper we long‐peduncle Cameroonian Impatiens sakeriana is...

Abstract The effect of transgenic maize MON 810 ( B t maize) on the diversity and abundance plant‐dwelling insects was tested under field conditions in southern ohemia (coordinates 48°N, 14ºE, 384 m a.s.l.) for three successive years. experiment carried out 10 0.5‐ha plots which five were seeded with non– parental cultivar. content toxin C ry1 A b) measured plant tissues a commercial ELISA kit. Randomly chosen plants (10 per plot) taken from during vegetation period about 2‐week intervals...

Abstract To verify the validity of concerns about environmental safety maize expressing insecticidal Cry toxins (referred to as Bt maize), we compared communities ground beetles (Carabidae), rove (Staphylinidae) and spiders (Araneae) in plots planted either with cultivar YieldGard ® or non‐transgenic parental Monumental. Each was grown on 5 0.5 ha for three consecutive years. increase field load toxin, fully first study year shredded small pieces that were ploughed into soil. Arthropods...

Comparative studies of co-occurring species using overlapping resources may help in understanding the mechanisms supporting biotic diversity species-rich regions, such as Mediterranean region Europe. Three Papilionidae butterflies, Archon apollinus, Zerynthia cerisy and polyxena, develop on Aristolochia plants co-occur Greek Thrace. We used mark–recapture to describe adult demography dispersal, searched for eggs larvae assess host microhabitat preferences. Adult flight timing followed a...

Přírodní rezervace Makyta (CHKO Beskydy, Česká republika) je rozsáhlé pestré území zahrnující přírodě blízké jedlobukové lesy se zbytky květnatých louček. Průzkumem v roce 2018 bylo zaznamenáno 284 druhů motýlů, z nichž 17 ohrožených a 3 jsou legislativně chráněné. Mezi nejvýznamnější druhy patřily šedovníček horský (Gesneria centuriella) – potvrzení výskytu na Moravě po 100 letech, pernatěnka čistcová (Alucita desmodactyla) druh významný pro ČR, centrum Beskydech, přástevník kostivalový...

Abstract Semi‐natural habitats in Europe host a substantial proportion of biodiversity, but they experience biodiversity loss due to ongoing agricultural changes. We regard the Rattle grasshopper ( Psophus stridulus ) as charismatic species species‐rich submontane xerothermic grasslands. To enable conservation and its habitat, we studied habitat preferences this formerly abundant grasshopper, now threatened declining many European countries. In 2011, applied capture‐mark‐recapture method...

Abstract Lasiommata petropolitana is a boreomontane butterfly, declining in Central Europe and not recorded the Czech Republic since 1975. Based on revision of all existing archival records results recent targeted surveys mountainous regions East Moravia, area its past occurrence, we document gradual retreat ultimate regional extinction. The historical range, marginal with respect to contiguous distribution along Carpathian mountain chain, included both foothills higher elevations Bílé...

In human-altered landscapes, specialist butterflies typically form spatially restricted populations, genetically differentiated due to dispersal restrictions. Generalists, in contrast, display minimum differentiation but high genetic diversity. While local-level actions suffice conserve specialists and landscape-level are necessary for generalists, information exists regarding conservation of species with intermediate features. We targeted two congeneric butterflies, the recently...

ABSTRACT Aim The distribution of within-species lineages has been affected by Quaternary climate changes, and population differentiation influenced species life histories. We investigated whether the individual mitochondrial genetic reflects constituent species’ traits. Using functionally diverse group butterflies, we examined which are present in Central Europe, an important suture zone. Location Czech Republic Western Palearctic. Taxon A total 140 butterfly species. Methods sequenced DNA...

Rozšíření vzácné ploštice zákeřnice pirátské (Peirates hybridus) v České republice prošlo průběhu 20. a 21. století významnými změnami. Tento druh vymizel z území dnešní ČR polovině století. Nicméně se opět vrátil rychle rozšířil i mimo původní areál. Zákeřnice pirátská byla znovuobjevena na Moravě po 50 letech roce 1998 2021 Čechách více než 100 letech. Na začátku rozšířila údolími velkých řek do dříve osídlených oblastí. Šíření druhu je pravděpodobně způsobeno kombinací faktorů...
