Meadow pipit ( Anthus pratensis ) egg appearance in cuckoo ( Cuculus canorus ) sympatric and allopatric populations
Host populations tend to show less ability to discriminate against parasites when living in their absence. However, comparison of rejection rates among sympatric and allopatric host populations does not allow determination of whether the greater tolerance in allopatric populations reflects a genetic change or phenotypic plasticity.

متن کاملMethylobacillus pratensis sp. nov., a novel non-pigmented, aerobic, obligately methylotrophic bacterium isolated from meadow grass.
Strain F31T was isolated from meadow grass (Poa trivialis L.) sampled from the city park in Helsinki. Analysis of phenotypic and genotypic properties showed the strain to be related to the group of obligately methylotrophic non-methane utilizing bacteria (methylobacteria) with the ribulose monophosphate pathway of formaldehyde assimilation.

متن کاملHybridization and apparent hybridization between meadow pipit (Anthus pratensis) and water pipit (A. spinoletta).
Occasionally, even a single breeding event may provide significant biological information, of which the present report of a pairing between a female meadow pipit (Anthus pratensis) and a male water pipit (A. spinoletta) may be a good example. Events of mixed-species pairing appear to be relatively common in birds (ARNOLD 1997). However, only rarely has researchers investigated whether such pair...
