Journal ArticleDOI

Camille Parmesan,Nils Ryrholm,Constantí Stefanescu,Jane K. Hill,Chris D. Thomas,Henri Descimon,Brian Huntley,Lauri Kaila,Jaakko Kullberg,Toomas Tammaru,W. John Tennent,Jeremy A. Thomas,Martin Warren +12 more
TL;DR: The authors showed that migratory species can respond rapidly to yearly climate variation, and further global warming is predicted to continue for the next 50-100 years, and some migratory animals can respond quickly to climate variation.
Journal ArticleDOI
Niche separation in space and time between two sympatric sister species—a case of ecological pleiotropy
Magne Friberg,Martin Bergman,Jaakko Kullberg,Niklas Wahlberg,Niklas Wahlberg,Christer Wiklund +5 more
TL;DR: It is suggested that the difference in phenology and voltinism between L. sinapis and L. reali is largely the result of environmentally implemented ecological pleiotropic effects caused by the between-species difference in habitat preference.
Journal ArticleDOI
Application of the Red List Index as an indicator of habitat change
Aino Juslén,Juha Pykälä,Saija Kuusela,Lauri Kaila,Jaakko Kullberg,Jaakko Mattila,Jyrki Muona,Sanna Elina Saari,Pedro Cardoso +8 more
TL;DR: The usefulness of the RLI as a tool for observing habitat change based on species threat assessment data is demonstrated, with several trends observed in accordance with studies focusing on particular taxa and habitats, and drivers for their change.
Journal ArticleDOI
Natural history of some Siberian melitaeine butterfly species (Nymphalidae: Melitaeini) and their parasitoids.
TL;DR: Observations on the larval gregarious behaviour, host plant use and parasitoids of six species of melitaeine butterfly in the Russian Republic of Buryatia show post-diapause larvae in two habitats, steppe and taiga forest region.
