The habitat is the basic unit for developments in life history, population dynamics, landscape ecology and conservation of organisms. It frequently treated as a particulate, invariant homogeneous entity (a patch). Here we examine implications using this concept butterfly biology. In doing so, suggest alternative approach applying functional resource‐based habitat. This recognises fundamental requirements organisms, consumables utilities, latter describing suitable environmental conditions...
Due to the attractiveness of butterflies, and their usefulness as model systems for biological questions, there has been a considerable amount material written on butterfly biology, largely in Europe. This book synthesizes all relevant recent knowledge field, which is must those making use this taxonomic group system. It divided into five major parts deal with habitat use, population ecology genetics, evolutionary ecology, distribution phylogeny, global change conservation. There are growing...
Abstract. 1. To determine whether rarity and decline is linked to organism ecology, associations have been examined between butterfly larval host‐plant competitive, stress‐tolerant, ruderal ( C‐S‐R ) strategies biology. 2. Associations sought mean scores for host plants with life history, morphology physiology variables, resource use, population attributes, geography, conservation status. Comparisons are carried out across species controlled phylogenetic patterning. 3. Butterfly biology...
Trait-based analyses explaining the different responses of species and communities to environmental changes are increasing in frequency. European butterflies an indicator group that responds rapidly with extensive citizen science contributions documenting abundance distribution. Species traits have been used explain long- short-term climate, land-use vegetation changes. Studies often characterised by limited trait sets being used, risks relative roles not fully explored. Butterfly...
Abstract Understanding the dynamics of biodiversity, including spatial distribution genetic diversity, is critical for predicting responses to environmental changes, as well effective conservation measures. This task requires tracking changes in biodiversity at large scales and correlating with species functional traits. We provide three comprehensive resources understand determinants mitochondrial DNA differentiation represented by (a) 15,609 COI sequences (b) 14 traits belonging 307...
The habitat selection and mate locating strategies of a woodland population Pararge aegeria (L.) were studied in relation to climatic conditions which can affect activity. At low air temperatures most individuals bask on rides, open areas with high basking site temperatures. With increasing temperature use sunlit patches within as sites, are lower than rides. Individuals alternate between flying but spend longer periods flight when highest. Mate males perching patrolling, not rigid...
Abstract Aim We compare the influence of contemporary geography and historical influences on butterfly diversity for islands in Aegean archipelago. Location The archipelago (Greece) two (Cyprus Megisti) Levantine Sea. Methods Thirty‐one were examined. Data are taken from own surveys (Coutsis Olivier) literature. Stepwise multiple regression is used to determine relationships between species richness, frequency, rarity endemicity against potential geographical predictors. logit predictors...
We sequenced small (s) RNAs from field collected honeybees (Apis mellifera) and bumblebees (Bombuspascuorum) using the Illumina technology. The sRNA reads were assembled resulting contigs used to search for virus homologues in GenBank. Matches with Varroadestructor virus-1 (VDV1) Deformed wing (DWV) genomic sequences obtained A. mellifera but not B. pascuorum. Further analyses suggested that prevalent population was composed of VDV-1 a chimera 5'-DWV-VDV1-DWV-3'. recombination junctions...
ABSTRACT. Egg‐laying by Pararge aegeria (L.) was studied in relation to host plant abundance, temperature and behaviour one woodland site central England. Eggs were laid on the undersides of leaves fifteen thirty‐one species grass located study site. Most deposited singly although several occasions a number females single leaf. There no clear relationship between abundance use, used being widespread abundant. eggs plants within range 24–30°C. In spring later summer these sites sunlit open...
Abstract Aim We describe fine‐scale diversity patterns of the entire butterfly fauna occurring on Tuscan Archipelago. By assessing traits associated with population diversification, haplotype uniqueness and extinction, we aim to identify factors determining origin maintenance genetic diversity, vulnerability environmental changes. Location Archipelago, Sardinia, Tuscany (Italy) Corsica (France). Methods built a mt DNA dataset (1,303 COI sequences) for 52 species reported in also including...
The mechanisms shaping island biotas are not yet well understood mostly because of a lack studies comparing eco-evolutionary fingerprints over entire taxonomic groups. Here, we linked community structure (richness, frequency and nestedness) genetic differentiation (based on mitochondrial DNA) in order to compare insular butterfly communities occurring key intercontinental area the Mediterranean (Italy-Sicily-Maghreb). We found that characteristics were influenced by combination contemporary...
Multivariate analyses of 393 butterfly species over 85 geographical areas (R- and Q-data matrices) in Europe North Africa have produced a consistent pattern faunal structures (units regions). Prominent features to emerge are the latitudinal zonation units division Mediterranean into western eastern components; southwards Europe, endemicity increases whereas decrease spatial dimensions. Central Europe–from Urals British Isles–forms single large structure (extent unit region). A model has been...
A hostplant-habitat model is described which explains fundamental differences in mate-locating behaviour between butterfly species, based on a sequence of spatially distinctive activities (habitual patrolling, localized perching, territoriality, lek assembly). It gives equal weight to phylogeny and ecology consistent with models for the evolution territoriality population structure. Perching repeatedly at characteristic sites, assembly evolve when resources become associated structures...

To distinguish between the influences of area and isolation on butterfly faunas British islands two approaches are adopted. First, species richness is related to island area, size faunal source. Neither nor account for much variance in richness, though more important than isolation. In contrast, corresponds closely source nearby that at proximate locations adjacent mainlands. The second approach relates incidence their ecological attributes. A very close relationship found those variables...
