Project

The role of generalist pollinators in agricultural landscapes ? Implications for plant population dynamics (GAP505/11/1589)

The proposed project attempts to assess the importance of generalist pollinators for population dynamics of common meadow plant species in landscapes with intensive agriculture. The focal group of pollinators are especially large hoverflies,...

Egg and hatching adaptations to brood parasite by a specialist, the Cuckoo (C.canorus), and the generalist, the Brown h. cowbird (M.ater) (IAA6087801)

In this study we intend to examine and compare aggshell and hatching adaptations exhibited by the two brood parasites, the North American generalist, the brown-headed cowbird and an Old World specialist, the Common cuckoo. The first goal of ...

The coexistence of aquatic invertebrates in spring fens the role of abiotic heterogeneity and biotic interactions at regional and local scale (GA16-03881S)

To reveal the means of species coexistence is essential for the understanding of biodiversity patterns. Isolated spring fens are inhabited by species-rich invertebrate assemblages, including many habitat specialists and generalists, for whic...

Calibrating post-feeding detection times of ingested weed seeds by carabid beetles (8J20AT021)

generalists will digest seeds of the same species. Thus, the detection times for seed DNA unpreferred seed species longer compared to generalists, thus DT50 will be longer. 3 of Carabidae, e.g. Harpalini and Zabrini, compared to m...

Powdery mildew (Ascomycetes Erysiphales) - an alternative food for the predatory mite Typhlodromus pyri Scheuten (Acari Phytoseiidae) (GA522/97/0323)

The predatory mite Typhlodromus pyri Scheuten is an important and effective agent for biological control of spider mites in many countries. It is a generalist species and the presence of alternative food is most likely a prerequisite for suc...

Speciation processes in orchids (KJB600870601)

Orchids are evolutionary young, extremely diversified plant family suitable for studying recent evolutionary processes. It has been suggested that selection for different pollinators is the main force behind orchid diversification. However, many orch...

Darwin wasps as a model of the parasitoid-host coevolution – an integrative approach (GA23-07303S)

We propose implementing an integrative approach to investigate the host range evolution of highly specialised hymenopteran parasitoids of spiders, Darwin wasps from the tribe Polysphinctini (Ichneumonidae, Pimplinae). We will unravel the host-specifi...
