Contoh conifer

• For conifers, mature male cones only were used for flowering phenology.

• Ten stands were located in mixed forests dominated by conifers (forest habitats), and ten stands were located in open agricultural landscapes (farmland habitats).

• Many individual ancient oaks are still to be found in current plantations of conifers, left simply because they were too difficult to remove.

• It was mainly the conifer plantations that were felled at this time.

• There was no significant relationship between duration of overlap and the amount of conifer present in each tetrad.

• Evaluation of several methods of canopy openness as predictors of photosynthetic photon flux density in deeply shaded conifer-dominated forest understorey.

• A similar situation occurred in conifers, until cuticle studies enabled species to be distinguished on reliable characters.

• Nevertheless, in many cases the woods produced by deciduous and evergreen conifers may be distinguished from one another on the basis of percentage skew values.

• The relationship between leaf longevity and growth ring markedness in modern conifer woods and its implications for palaeoclimatic studies.

• This unique community structure probably reflects the distinct chemical defences of this tree species compared to the other conifer species.

• When feeding occurs on young conifer transplants, this weevil causes significant economic damage.

• Within this area, much of its former range has been lost to conifer plantations and some to agricultural conversion.

• The high concentration of total sugars in larch reflects dormant season storage in the bark of this deciduous conifer.

• There have been relatively few instances, however, of the more specific and damaging exotic pests of these conifers colonizing this new environment.

• Inherent variation in duct size between the three conifer species appears to determine their relative susceptibility.
