Modelling single nucleotide effects in phosphoglucose isomerase on dispersal in the glanville fritillary butterfly: coupling of the demographic dynamics impose a number of selection pressures at the pgi locus elevated population turnover rate in highly fragmented landscapes selects for the c allele, especially when the metapopulation is at. More recently, pgi has been identified as a candidate locus affecting flight metabolic rate and fecundity in a large metapopulation of the glanville fritillary butterfly (melitaea cinxia) (haag et al, 2005 saastamoinen, 2007.
Molecular-level variation affects population growth in a butterfly metapopulation molecular-level variation affects population growth in a butterfly metapopulation ilkka hanski, we show that the allelic composition of the glycolytic enzyme phosphoglucose isomerase (pgi). However, a direct covariation pattern with pgi is likely because phosphoglucose isomerase is a metabolic enzyme involved in glycolysis, hence important for atp-based energy supplies (watt 1985), and pgi genotypes have been shown to differ in enzymatic activity (watt 1992 dahlhoff & rank 2000. Locus of phosphoglucose isomerase (pgi) in coexisting populations of patella aspera, p coerulea and p lusitanica this enzyme, whose variability was studied horn population other marine molluscs the pg1 active form is a dimer (levinton, 1973 snyder and gooch, 1973 willuns and.
Phosphoglucose isomerase (pgi ) in the glanville fritillary butterfly (establishment of the population) phoshoglucose isomerase (pgi ) — the gene that encodes a glycolytic enzyme phosphoglucose isomerase (pgi, also known and allozyme locus as pgi, whereas the genetic locus is called pgi in the glanville fritillary, the two. A single nucleotide polymorphism (snp) at the phosphoglucose isomerase (pgi) locus, which has two alleles – a and c - has been proven to show a strong association with individual variation of dispersal and fitness, with balancing selection via a heterozygote advantage conferring increased dispersal ability and fitness to migrant females relative to homozygotes of both allele types (mattila & hanski, 2014 niitepõld et al, 2009 orsini et al, 2009. Sd schoville, jm flowers, rs burtondiversifying selection underlies the origin of allozyme polymorphism at the phosphoglucose isomerase locus in tigriopus californicus plos one , 7 ( 2012 ) , p.
Allozyme variation at the phosphoglucose isomerase (pgi) locus in the glanville fritillary butterfly (melitaea cinxia) is associated with variation in flight metabolic rate, dispersal rate, fecundity and local population growth rate.
Phosphoglucose isomerase genotype effects on life history depend on latitude and food stress authors phosphoglucose isomerase (pgi) food stress sensitivity and flight performance across phosphoglucose isomerase enzyme genotypes in the sooty copper butterfly population ecology,.
Population growth rate ( r) is plotted against the logarithm of population size ( n t a), regional change in population sizes ( n trend b), and pgi genotype frequency f (c) in panel (c), populations in small ( a 08 ha) and large habitat patches have been identified with closed (continuous line) and open symbols (broken line), respectively. Allozyme variation at the phosphoglucose isomerase (pgi) locus in the glanville fritillary butterﬂy (melitaea cinxia) is associated with variation in ﬂight metabolic rate, dispersal rate, fecundity and local population growth.
