Sexual and postmating reproductive isolation between allopatric Drosophila montana populations suggest speciation potential
(BioMed Central, 2011)
Background - Widely distributed species with populations adapted to different environmental conditions can provide valuable opportunities for tracing the onset of reproductive incompatibilities and their role in the ...
Genetic and potential non-genetic benefits increase offspring fitness of polyandrous females in non- resource based mating system
(BioMed Central (BMC), 2010)
Background: The adaptive significance of female polyandry is currently under considerable debate. In non-resource based mating systems, indirect, i.e. genetic benefits have been proposed to be responsible for the fitness ...
Negative density-distribution relationship in butterflies
(BioMed Central, 2005)
Background.
Because "laws of nature" do not exist in ecology, much of the foundations of community ecology rely on broad statistical generalisations. One of the strongest generalisations ...
Changes in gene expression linked with adult reproductive diapause in a northern malt fly species: a candidate gene microarray study
(BioMed Central (BMC), 2010)
Background:
Insect diapause is an important biological process which involves many life-history parameters important for survival and reproductive fitness at both individual and population level. Drosophila montana, a ...
Phylogeny and evolution of parthenogenesis in Finnish bagworm moth species (Lepidoptera : Psychidae : Naryciinae) based on mtDNA-markers
(Finnish Zoological and Botanical Publishing Board, 2005)
We investigated species diversity and evolution of parthenogenesis among bagworm moth species of Dahlica and Siederia using mitochondrial DNA sequencing. Parthenogenesis is rare among Lepidoptera other than Psychidae. ...
The parasitoid species complex associated with sexual and parthenogenetic Naryciinae (Lepidoptera: Psychidae): Integrating ecological and molecular analyses
(Institute of Entomology of the Czech Academy of Sciences, and Czech Entomological Society, 2011)
This study describes the parasitoid species complex associated with seven closely related species of sexual (Siederia rupicollella, S. listerella, Dahlica lazuri, D. charlottae and D. lichenella) and parthenogenetic (Dahlica ...
Truncated forms of viral VP2 proteins fused to EGFP assemble into fluorescent parvovirus-like particles
(BioMed Central (BMC), 2006)
Fluorescence correlation spectroscopy (FCS) monitors random movements of fluorescent molecules in solution, giving information about the number and the size of for example nano-particles. The canine parvovirus VP2 structural ...

The lamellicorn beetles of southern Sardinia (Coleoptera: Scarabaeoidea)
(SIAP, 2011)
A faunistic inventory of lamellicorn beetles has been conducted in southern Sardinia (former province of Cagliari) based on literature and collection
records, as well as on new fi ndings from recent fi eld expeditions ...
