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. Here we test the existence of changes in a host’s adaptation to...

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. Phylogenetic analysis showed the strain to be closely ...
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...
متن کاملSeparation of Chlorophyll Degradation from Other Senescence Processes in Leaves of a Mutant Genotype of Meadow Fescue (Festuca pratensis L.).
Chlorophyll levels in l-cm sections of the youngest fully expanded leaves of normal (Y) Festuca pratensis L. declined almost to zero over a period of 6 days after excision. Chlorophyll in a mutant genotype (NY) remained near the initial level for the whole of this period. Abscisic acid promoted pigment loss in Y but had no significant effect on chlorophyll in NY. Kinetin retarded pigment loss i...
