The second most abundant group was the Myristicaceae (second most speciose group) from which 50 fruiting plants/ha were phenologically active.
Significant positive correlations between specific leaf dry mass and fresh leaf mass based relative consumption rates revealed that larvae of the three phenologically latest species, P.
(North Dakota), after leaves in the overstory had fully expanded and when Dirca palustris were similar phenologically at all sites (Table 1).
The maintenance of large populations of Campanula species whose anthesis coincides more or less phenologically with the activity period of C.
Vegetation is phenologically young at this time and has a low ratio of fiber to protein content, which supports both dam lactation and tissue deposition once rumen function develops in the offspring (Chapin et al., 1980; White, 1992; Griffith et al., 2002; Post et al., 2003; Knott et al., 2004).
"My preference would be to only use grapes that are perhaps lacking in color due to growing conditions, but I would want them to be phenologically ripe.
The objectives of this study were to (i) determine AFIS [L.sub.W] of TAM 94L-25, TAM 94M-14, and a number of medium staple genotypes varying in fiber length when grown under irrigated conditions, (ii) determine the FLDP using [L.sub.W], and (iii) determine phenologically how TAM 94L-25 and TAM 94M-14 attain their longer average fiber length.
This lack of response suggests that Elymus is either phenologically constrained, in that it is only able to garner nutrients from spring pulses (Bilbrough and Caldwell 1997), or that some factor was counteracting the positive response expected from Elymus.
The more rapid decline in leaf number in the BS line by day 24 suggests that these plants are phenologically ahead of the BC line.
Phenologically, all Poecilimon are typical spring species, with a remarkable earlier appearance than most other bushcrickets, and an adult season lasting for around four weeks (e.g., Lehmann & Lehmann 2006).
A strong and positive correlation between seed yield and biomass, similar to that reported by Erskine (1983) for 3586 accessions in what was at that time the world lentil germplasm collection grown in Syria, was found whenever the genotypes investigated here were phenologically suited to their production environment.
They hypothesized that this might he due to persistent canopy cover not allowing differentiation of understory species phenologically. A study investigating variation in light transmission in oak and northern hardwood forest found that the reduction of incident radiation in the lower layers was related to the shade tolerance of overstory trees (Canham et al., 1994).
