1. Effects of Farming Practice on Pollinators and Pollination across Space and Time
Sammanfattning : Several studies have found that organic farms support higher biodiversity, but results vary between studies such that some also show no or even negative effects. There can be many reasons why studies comparing organic and conventional farming show conflicting results. LÄS MER
2. Effects of created habitats on farmland biodiversity
Sammanfattning : Agricultural intensification has caused severe declines among biodiversity in European farmland over the last half century. The transformation of the agricultural landscape has led to reduced availability of key resources such as food, nesting habitat and shelter. LÄS MER
3. Flower Cues for Hawkmoths: Colour, Place and Odour
Sammanfattning : Flowers use different cues to attract pollinators including colour and odour. How do hawkmoths use these cues to find the flowers? This question was investigated in two species of hawkmoth, the diurnal species, Macroglossum stellatarum, and the nocturnal species, Deilephila elpenor. Both species have colour vision and D. LÄS MER
4. Insect Diversity in Changing Landscapes
Sammanfattning : During recent decades, concern about the loss of biodiversity has increased. To change this negative trend there is an urgent need for effective conservation measures and there are ample evidence that conservation of organisms without an understanding of their ecology and behaviour is impossible.
