Great tits (Parus major) are sometimes found to incubate in their nests even though the nests contain no eggs. This phenomenon has been observed in different parts of Europe (Sweden, Finland, UK, Netherlands, Germany) and it has become more common during the 1980s. We analysed the occurrence of empty nests in P. major and in pied flycatcher (Ficedula hypoleuca) in SW Finland from 6-year data co...

BACKGROUND Salvia divinorum is a non-water-soluble hallucinogen that is becoming increasingly popular among adolescents. Salvia is a highly selective full agonist of primate and cloned human cerebral kappa-opioid receptors, although its psychotomimetic effects are similar to serotonergic agonists and NMDA glutamate antagonists. Salvia has been associated with depersonalization, laughter, feelin...

The main goal of this study was to identify the treatment that increases the populations of spiders, which are effective predators in agroecosystems. In 2013 and 2014 the experimental eggplant (Solanum melongena L.) field was two different treatments, organic fertilizers and chemical fertilizer treatment, and in 2014 we surrounded organic fertilizer plots with the flowering plants mealy cup sag...

BACKGROUND AND AIMS A test was made of the hypothesis that papilionate legume flowers filter pollinators according to their ability to exert strength to open flowers to access rewards. In addition, interactions with pollen vectors were expected to explain the structural complexity of the architecture of these flowers since operative flower strength may be determined by a combination of morpholo...

The genetic diversity and population structure of Salvia lachnostachys Benth were assessed. Inter Simple Sequence Repeat (ISSR) molecular markers were used to investigate the restricted distribution of S. lachnostachys in Parana State, Brazil. Leaves of 73 individuals representing three populations were collected. DNA was extracted and submitted to PCR-ISSR amplification with nine tested primer...
