Abstract The goal of this study was to quantitatively evaluate the individual and interactive effects of weed control, nitrogen fertilization, and seed source on Douglas-fir (Pseudotsuga menziesii) survival and growth in a range of sites and growing conditions in western Oregon. Weed control was the dominant factor influencing seedling survival and growth and accounted for 49% of the explained variation in seedling volume after 2 yr. Nitrogen fertilization had no effect when used in conjunction with weed control and a negative effect when used without weed control. Seedlings from a seed orchard source were significantly larger in diameter and volume than those from a wild local source after two growing seasons, but second-year heights were similar for the two seedling types. Initial seedling size was positively correlated with growth rate. West. J. Appl. For. 11(2):00-00.

Treatment Application

Amphibians face a variety of anthropogenic environmental perturbations that could act alone or in combination to influence population size. We investigated interactive effects of warming conditions, a moderate pulse of nitrogen pollution, and conspecific density on larvae of the common frog, Rana temporaria. The 16-day experiment had a 2 × 2 × 2 factorial design implemented in 80-l outdoor mesocosms. High density and warm temperature both resulted in reduced activity and visibility; tadpoles grew and developed more quickly at low density and high temperature. The high-nitrogen treatment did not influence behavior, growth, or development rate. We attribute this to several realistic features of our study, including a pulsed treatment application and natural denitrification within the mesocosms. There was only a single interaction among the three factors: higher temperature exacerbated density-dependence in growth rate. These results illustrate that climate warming may benefit temperate amphibians, although the benefits may be counteracted by enhanced larval crowding.

The effect of the surrounding community and spatial extent of disturbance on recruitment was investigated in a mixed stand (dominated by large brown algae of the order Fucales) on a subtidal rocky platform in South Australia. In particular, survival and growth of Cystophora and Sargassum recruits on natural substratum were examined in artificially cleared areas of three sizes (30 × 30 cm, 60 × 60 cm and 100 × 100 cm). Abundance and growth of recruits was monitored for 6 months at both the edge and the centre of the clearances. The influence of clearance size and position within a clearance on the abundance of recruits changes with time. Initially, the size of clearance was most important, with larger clearances supporting denser stands of recruits. However, after 143 days, position within the clearance became important, with greater mortality at the edges than at the centre. The large residual values associated with the analysis were evidence of the variability of the interactions within this community. The results demonstrate the importance of the consideration of spatial and temporal scales, and particularly the position within a disturbed area, in recruitment studies.
