Dry grassland butterflies of European interest under climate changes (Colias myrmidone, Parnassius apollo, Phengaris arion)
Faltýnek Fric, Zdeněk; Konvička, Martin; Rindoš, Michal; Sucháčková Bartoňová, Alena; Spitzer, Lukáš; Vrba, Pavel
2023 - Czech
The methodology summarizes the principles of the habitat conservation of several butterflies - Phengaris arion, Parnassius apollo and Colias myrmidone, species specialized to dry grasslands, rock screes and similar habitats, under different scenarios of climate change. Maps of future climatically suitable habitats are included, together with an analysis of the possibilities of assisted colonization. Metodika shrnuje zásady péče o stanoviště modráska černoskrvnného (Phengaris arion), jasoně červenookého (Parnassius apollo) a žluťáska barvoměnného (Colias myrmidone), specializovaných druhů suchých trávníků, skalních drolin a podobných stanovišť, s variantami pro různé scénáře klimatické změny. Součástí jsou mapy budoucích klimaticky vhodných stanovišť, spolu s rozborem možností asistovaných kolonizací.

Methodology for co-cryostorage of virus isolates in their host plants and relevant data
Bilavčík, A.; Bjerkestrand, R.; Bjelland, B.; Blystad, D.-R.; Bobrova, O.; Fránová, Jana; Faltus, M.; Hamborg, Z.; Hammond Hammond, S. D.; Koloniuk, Igor; Zámečník, J.

Currently, the nursery production of plant material emphasizes the production of healthy, virus-free material. For this reason, it is necessary to have reference plant materials in which the virus is present. Some types of viruses are difficult to maintain outside the plant host. Because of the potential transmission to outdoor plantings, it is necessary to keep infected plants in special cultivation areas, and net-houses, which brings considerable financial and labour costs. Therefore, a methodology was developed in which the virus status in plant material is analysed, the infected material can be stored using cryopreservation in liquid nitrogen and then regenerated in vitro, and relevant data in GeneEver cryobox can be stored.

Endangered butterflies of lowland forests under climate change
Konvička, Martin; Beneš, Jiří; Číp, D.; Sobík, D.; Spitzer, L.; Faltýnek Fric, Zdeněk; Rindoš, Michal; Vrba, Pavel
2023 - Czech
The material compiles conservation measures and methods for the care of endangered butterflies of open forests, protected by the EU Habitat Directive in the Czech Republic and under climate changes. These species are Euphydryas maturna, Lopinga achine, Parnassius mnemosyne, Coenonympha hero, and partially also Zerynthia polyxena. It results from predictions of vegetational and climatic changes of forest habitats, and outlooks of forest and water management conditions. Metodika, shrnující zásady péče o populace hnědáska osikového (Euphydryas maturna), okáče jílkového (Lopinga achine), jasoně dymnivkového (Parnassius mnemosyne), okáče hnědého (Coenonympha hero) a částečně pestrokřídlece podražcového (Zerynthia polyxena), druhů světlých lesů chráněných Směrnicí o stanovištích EU, v podmínkách měnícího se klimatu. Vychází z predikcí vegetačních a mezoklimatických změn lesních biotopů, výhledů lesního hospodářství v ČR a vodohospodářských poměrů.
