Cím:Maculinea rebeli (Hirschke) - a phantom or reality? : Novel contribution to a long-standing debate over the taxonomic status of an enigmatic Lycaenidae butterfly / Bereczki Judit, Pecsenye Katalin, Varga Zoltán, Tartally András, Tóth János P.

Megjegyzések:The main goal of our research was to carry out a comprehensive study on the obligatorily myrmecophilous Maculinea alcon (Denis & Schiffermüller) whose taxonomy has remained highly debated despite the fact that Maculinea Van Eecke species are some of the most intensively studied insects in Europe. We aimed to elucidate the relationship between the different forms exploiting different ecological environments with specific regard to ♭Hirschke's rebeli' (M. rebeli (Hirschke)) from the high altitudes of the Styrian Alps which was studied in this respect for the first time. Molecular analyses including multiple gene sequences, microsatellites and allozymes completed with Wolbachia screening, together with geometric morphometry were applied on various sets of samples. Our results showed that ♭rebeli' from the type locality differed strongly from all other samples not only at the highly variable microsatellites, but also at standard genes and clearly represents a well?separated unit (potentially subspecies) within M. alcon. As all individuals were infected with a single Wolbachia strain, this is possibly an ancient infection with high maternal transmission rate. It also suggests that the separation of the topotypic populations was probably a relatively recent event which could have been promoted by genetic drift or specific conditions at high altitudes, and maintained by restricted gene flow. Both the genetic and the morphometric studies supported the proposition that the geographical origin of the populations has a higher effect on the structure of variation than the food plant use. Moreover, we detected more genetic lineages than could be defined by differential host plant usage.

Cím:Contrasting genetic structure in cuckoo and predatory Maculinea butterflies / Katalin Pecsenye, Judit Bereczki, Edit Juhász, András Tartally, Zoltán Varga
Dátum:2015
ISSN:1566-0621
Megjegyzések:In Europe, bothMaculinea alconandM. teleiusfrequently co-occur inhabiting humid meadows. Althoughtheir parasitic life cycle is similar, ecological differenceshave been demonstrated between them: (i) spatial distri-bution of their eggs is different, and (ii)M. alconis acuckoo species, whileM. teleiusis predatory. The aim ofthe present study is to identify the genetic consequences ofthe ecological differences between these two butterflyspecies. To do so, we studied the genetic structure insamples from 9M. alconand 16M. teleiussites obtainedfrom the Carpathian Basin using 16 polymorphic enzymemarkers. Both species exhibited relatively low enzymepolymorphism compared to other lycaenid species. Nev-ertheless, all measures of variation were significantlyhigher inM. teleiusthan inM. alcon. Genetic differen-tiation, however, was generally higher amongM. alconpopulations as compared toM. teleius. Moreover, the re-sults of Bayesian clustering indicated a clear regionalpattern with three well-defined cluster regions inM. alcon.In contrast, the regional pattern was less evident inM.teleiuswhere we found three comparatively less distinctcluster regions. Putatively adaptive genetic differenceswere detected among cluster regions exploiting differenthost ants inM. alcon, while they were less evident inM.teleius. These results conform to our predictions on thedifferences between the utilization of their host ants. Sincethe pattern of genetic differentiation is different in the twoMaculineaspecies, conservation strategies need also todiffer in their cases.
