| Abstract |
We examined how acceptability characteristics displayed by 28-day-old seedlings of 12 species of Western Australian Proteaceae affect the likelihood of seedling herbivory in the field. The seedling attributes quantified were cotyledon phenolic, cyanide and nitrogen concentrations, and cotyledon area, thickness and specific leaf area. Only phenolic content was significantly correlated (negatively) with field rates of herbivore attack. This finding shows that the phenomenon of selective herbivore attack on seedlings may be influenced by a specific plant life-history trait, (in this case cotyledon phenolic concentration). In addition, we also studied the interaction between fire, serotiny and herbivory in matched burned and unburned plots. Although herbivore activity was greater in unburned plots, weakly serotinous species were as prone to defoliation as congeneric, strongly serotinous species, even though their seedlings recruit successfully in the absence of fire. This result suggests that seedlings of species able to establish between fires are not better defended against the higher levels of herbivory normally associated with unburned vegetation. |

Attention Score in Context
This research output has an Altmetric Attention Score of 3. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 24 February 2010.
All research outputs
#7,453,479
of 22,786,691 outputs
Outputs from Oecologia
#1,674
of 4,210 outputs
Outputs of similar age
#26,232
of 113,382 outputs
Outputs of similar age from Oecologia
#9
of 27 outputs
Altmetric has tracked 22,786,691 research outputs across all sources so far. This one is in the 44th percentile – i.e., 44% of other outputs scored the same or lower than it.
So far Altmetric has tracked 4,210 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 7.0. This one is in the 34th percentile – i.e., 34% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 113,382 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 17th percentile – i.e., 17% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 27 others from the same source and published within six weeks on either side of this one. This one is in the 18th percentile – i.e., 18% of its contemporaries scored the same or lower than it.
