Northern and mountainous ice sheets have expanded and contracted many times due to ice ages. Consequently, temperate species have been confined to refugia during the glacial periods wherefrom they have recolonized warming northern habitats between ice ages. In this study, we compare the gene CYP405A2 between different populations of the common burn...

Artemisia chamaemelifolia Vill. is a perennial herb from the genus Artemisia of the Asteraceae family. This plant is mostly distributed in Armenia, Russia, Georgia and the Eurasian mountains including Cantabrian chain, Spanish Sierra Nevada, the Alps (France and Italy), Azerbaijan, Pyrenees, the Balkan range (Bulgaria), northeast and east Anatolia...

Beech (Fagus sylvatica L.) is one of the most important forest trees in Europe and its current broad expanse over the continent is believed to be the outcome of the Holocene postglacial expansion of lineages originating from different glacial refugia. Studies using gene markers, pollen profiles and fossils suggest the main locations of glacial refu...
The series Eurasiatica. Quaderni di Studi su Balcani, Anatolia, Iran, Caucaso e Asia Centrale was born to deal specifically with a wide area, composite but interrelated that, in addition to the traditional historical and cultural significance, is taking on an increasing political and economic value. The placement of this series within Edizioni Ca’...
By sequencing 727 ancient individuals from the Southern Arc (Anatolia and its neighbors in Southeastern Europe and West Asia) over 10,000 years, we contextualize its Chalcolithic period and Bronze Age (about 5000 to 1000 BCE), when extensive gene flow entangled it with the Eurasian steppe. Two streams of migration transmitted Caucasus and Anatolian...
We explore the genetic diversity and phylogeography of the dragonflies Orthetrum cancellatum and O. coerulescens in Europe based on mitochondrial and nuclear DNA. Orthetrum cancellatum has a clear division between a group comprising Maltese, Italian, and central and northern European populations, and a group comprising mainly populations from south...

... There are 98 described species of burnet moths in Zygaena (Hofmann & Gerald Tremewan, 2005). Some Zygaena species have become model organisms to study the evolution of chemical defence compounds (Zagrobelny et al., 2019). Forewings of Z. filipendulae are black and distinctively marked with six red spots. ...
... This species can biosynthesize cyanogenic glucosides de novo, or obtain them from Fabaceae host plants, storing cyanoglucosides in cuticular cavities and hemolymph, for later use as a defensive secretion (Franzl et al., 1986). The three enzymes involved in the evolution of biosynthesis in Z. filipendulae are cytochrome CYP405A2, CYP332A3, and glucosyl transferase UGT33A1 (Zagrobelny et al., 2019). A genome of Z. filipendulae is much needed especially in order to understand the genetics of cyanogenic glucoside biosynthesis. ...
We present a genome assembly from an individual female Zygaena filipendulae (6-spot burnet; Arthropoda; Insecta; Lepidoptera; Zygaenidae). The genome sequence is 365.9 megabases in span. The majority of the assembly (99.99%) is scaffolded into 31 chromosomal pseudomolecules, with the W and Z sex chromosomes assembled. The complete mitochondrial genome was also assembled and is 15.6 kilobases in length. Gene annotation of this assembly on Ensembl has identified 12,493 protein coding genes.
... By limiting transparent burnet dispersal, bracken cover may fragment suitable habitat into isolated patches that experience limited migration, thus enforcing a metapopulation structure (Hill et al. 1996). As burnets cannot colonise new areas prior to the establishment of their foodplant and microclimatic conditions (Zagrobelny et al. 2019), populations may be highly susceptible to the adverse effects of habitat fragmentation (Habel et al. 2012). ...
Ecosystem engineers affect other organisms by creating, maintaining or modifying habitats, potentially supporting species of conservation concern. However, it is important to consider these interactions alongside non-engineering trophic pathways. We investigated the relative importance of trophic and non-trophic effects of an ecosystem engineer, red deer, on a locally rare moth, the transparent burnet ( Zygaena purpuralis ). This species requires specific microhabitat conditions, including the foodplant, thyme, and bare soil for egg-laying. The relative importance of grazing (i.e., trophic effect of modifying microhabitat) and trampling (i.e., non-trophic effect of exposing bare soil) by red deer on transparent burnet abundance is unknown. We tested for these effects using a novel method of placing pheromone-baited funnel traps in the field. Imago abundance throughout the flight season was related to plant composition, diversity and structure at various scales around each trap. Indirect effects of red deer activity were accounted for by testing red deer pellet and trail presence against imago abundance. Imago abundance was positively associated with thyme and plant diversity, whilst negatively associated with velvet grass and heather species cover. The presence of red deer pellets and trails were positively associated with imago abundance. The use of these sites by red deer aids the transparent burnet population via appropriate levels of grazing and the provision of a key habitat condition, bare soil, in the form of deer trails. This study shows that understanding how both trophic and non-trophic interactions affect the abundance of a species provides valuable insights regarding conservation objectives.
