| Abstract |
The spongeLissodendoryx isodictyalis is an odorous, encrusting, blue-gray sponge found on subtidal flats in North Carolina waters. The strong odor ofL. isodictyalis, coupled with the observation that it is rarely overgrown by fouling organisms, suggested that this sponge may produce metabolites with potent antifouling activity. Ethyl acetate extracts ofL. isodictyalis inhibit larval settlement of the barnacleBalanus amphitrite in laboratory assays at 10 ng/ml. Barnacle settlement bioassays of isolated preparative TLC fractions show thatL. isodictyalis produces at least two pungently scented, antifouling agents with EC50 values of less than 85 μg/ml and less than 250 μg/ml, respectively. The most potent agent inhibits settlement at or below a concentration of 400 ng/ml and kills approximately 25 % of settlement-stage barnacle larvae at 400 μg/ml. The other agent causes 100% mortality of larvae at concentrations greater than 400 μg/ml and inhibits settlement at approximately 40 μg/ml. These metabolites ofL. isodictyalis may inhibit overgrowth of the sponge in nature. |

Attention Score in Context
This research output has an Altmetric Attention Score of 6. 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 23 November 1999.
All research outputs
#4,710,483
of 22,849,304 outputs
Outputs from Journal of Chemical Ecology
#302
of 2,052 outputs
Outputs of similar age
#1,865
of 15,818 outputs
Outputs of similar age from Journal of Chemical Ecology
#2
of 22 outputs
Altmetric has tracked 22,849,304 research outputs across all sources so far. Compared to these this one has done well and is in the 76th percentile: it's in the top 25% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 2,052 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 6.1. This one has done well, scoring higher than 78% of its peers.
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 15,818 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 74% of its contemporaries.
We're also able to compare this research output to 22 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 68% of its contemporaries.
