The range of hosts exploited by a parasite is determined by several factors, including host
availability, infectivity and exploitability. Each of these can be the target of natural selection …

Understanding connectivity among populations in fragmented landscapes is of paramount
importance in species conservation because it determines their long-term viability and helps …

Land use intensification is a general threat to biodiversity, but many species depend on low‐
intensity agricultural ecosystems. One example is European mountain meadow ecosystems …

Genetics has been widely used in insect ecology and conservation. To minimise the effect of
DNA sampling on organisms as much as possible, it would be ideal to use non‐invasive or …

The main goal of our research was to carry out a comprehensive study on the obligatorily
myrmecophilous Maculinea alcon (D enis & S chiffermüller) whose taxonomy has remained …

Phengaris alcon is an endangered, ant-associated butterfly found, amongst other places, in
Denmark, where it has undergone a severe decline during the last century. However, the …

Biotic interactions are often acknowledged as catalysers of genetic divergence and eventual
explanation of processes driving species richness. We address the question, whether …

Host specialization is an ubiquitous character in aphid populations. Many polyphagous
aphid populations usually consist of several subpopulations that have strong fidelity to a …

Simple Summary The disappearance of many butterfly species is currently observed in
Europe, as most of them display strict habitat preferences and/or food specializations. A …
