40August transect data analyses (TABLE5) showed that MIP changedsignificantly (P < 0.01) with changes ininitial percent cover and soil moisturepercent. Change in initial soil pH had nosignificant (P = 0.063) effect on MIP.Change in percent cover had significant(P < 0.01) effects on soil moisturepercent and soil pH. Also, changes insoil moisture percent had significant (P< 0.01) effects on soil pH. MIP changedsignificantly with changes in the initialinteraction of percent cover and moisturepercent, and percent cover and pH andmoisture percent (P = 0.022, and 0.033respectively). No significant differenceswere found between MIP and the initialinteraction of percent cover and pH, andpH and moisture percent (P = 0.070, and0.306 respectively).TABLE 5 August transect data forpercent cover, moisture percent, pH, andmycorrhizal inoculum potential (MIP) inundisturbed sand dunes. In eachquadrate, percent cover is the total plantspecies cover; MIP values are the meanof at least three samples.NS = Non significant, * = Significant atP = 0.05, and ** = Significant at P =0.01.Analyses of the combined data fromJune, July, and August transects(TABLE 6) showed that MIP changedsignificantly with change in initial dateof sampling (P = 0.025), percent cover(P < 0.01), moisture percent (P < 0.01),and pH (P = 0.035). Also, MIP changed
41significantly with changes in the initialinteraction of date of sampling andmoisture percent, date of sampling andpH, and pH and moisture percent (P =0.048, 0.005, and < 0.01, respectively).However, no significant differenceswere found between MIP and changes inthe interaction of date of sampling andpercent cover, percent cover andmoisture percent, percent cover and pH,or date of sampling, percent cover, pHand moisture percent (P = 0.209, 0.337,0.901, and 0.495 respectively). Changesin the initial date of sampling hadsignificant (P = 0.05) effects on percentcover, moisture percent (P < 0.01), andpH (P < 0.01). Change in the initialpercent cover had significant (P < 0.01)effects on moisture percent and pH.Also, changes in the initial moisturepercent had significant (P < 0.01) effectson pH.For the combined data (TABLE 6),Tukey’s test of pairwise comparisonprobabilities of MIP means in the June,July, and August transects showed thatMIP (18.2 ± 2.03) of the June transectdiffered significantly (P = 0.024) fromMIP (9.8 ± 3.69) of the July transect,and there was a significant (P < 0.01)difference between MIP (9.8 ± 3.69) ofthe July transect and MIP (19.6 ± 3.49)of the August transect. However, nosignificant (P = 0.596) differences werefound between MIP (18.2 ± 2.03) of theJune transect and MIP (19.6 ± 3.49) ofthe August transect. There weresignificant differences (P < 0.01)between pH means (6.7 ± 0.05, 6.3 ±0.05, and 5.8 ± 0.09) in the June, July,and August transects, respectively.Moisture percent (2.1 ± 0.19) of the Junetransect differed significantly (P =0.001) from moisture percent (0.9 ±0.13) of the August transect. Nosignificant (P = 0.209) difference wasfound between moisture percent (2.1 ±0.19) of the June transect and moisturepercent (1.2 ± 0.23) of the July transect.Also, no significant (P = 0.079)difference was found between moisturepercent (1.2 ± 0.23) of the July transectand moisture percent (0.9 ± 0.13) of theAugust transect. Percent cover (71.0 ±6.8) of the June transect wassignificantly (P = 0.043) different frompercent cover (62.2 ± 8.3) of the Julytransect. Also, percent cover (71.0 ±6.8) of the June transect wassignificantly (P = 0.022) different frompercent cover (55.2 ± 6.8) of the Augusttransect. No significant (P = 0.753)difference was found between percent
