The obliquebanded leafroller, Choristoneura rosaceana (Harris), is one of the major arthropod pests of apple in the United States. In 1999 and 2000, a survey of the obliquebanded leafroller parasitoid complex in commercially managed apple orchards in Michigan's two largest fruit production regions was conducted to determine the species present and their importance to obliquebanded leafroller po...

Skates (Rajiformes: Rajoidei) are common mesopredators in marine benthic communities. The spatial associations of individual species and the structure of assemblages are of considerable importance for effective monitoring and management of exploited skate populations. This study investigated the spatial associations of eastern North Pacific (ENP) skates in continental shelf and upper continenta...

It is generally accepted that cases of species' polyphyly in COI trees arising as a result of deep intraspecific divergence are negligible, and the detected cases reflect misidentifications or/and methodological errors. Here we studied the problem of species' non-monophyly through chromosomal and molecular analysis of butterfly taxa close to Melitaea didyma (Esper, 1779) (Lepidoptera, Nymphalid...

Background: Internet trade popularize the ornamental interest of plants but can also threaten species’ wild populations, if this activity is performed in uncontrolled and unauthorised ways.
