| Abstract |
Diatoms are species-rich microalgae that often have a unique life cycle with vegetative cell size reduction followed by size restoration through sexual reproduction of two mating types (MT(+) and MT(-)). In the marine benthic diatom Seminavis robusta, mate-finding is mediated by an L-proline-derived diketopiperazine, a pheromone produced by the attracting mating type (MT(-)). Here, we investigate the movement patterns of cells of the opposite mating type (MT(+)) exposed to a pheromone gradient, using video monitoring and statistical modeling. We report that cells of the migrating mating type (MT(+)) respond to pheromone gradients by simultaneous chemotaxis and chemokinesis. Changes in movement behavior enable MT(+) cells to locate the direction of the pheromone source and to maximize their encounter rate towards it. |

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 08 May 2018.
All research outputs
#12,899,167
of 22,876,619 outputs
Outputs from Microbial Ecology
#1,143
of 2,058 outputs
Outputs of similar age
#166,090
of 339,345 outputs
Outputs of similar age from Microbial Ecology
#29
of 43 outputs
Altmetric has tracked 22,876,619 research outputs across all sources so far. This one is in the 43rd percentile – i.e., 43% of other outputs scored the same or lower than it.
So far Altmetric has tracked 2,058 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 5.4. This one is in the 43rd percentile – i.e., 43% 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 339,345 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 50% of its contemporaries.
We're also able to compare this research output to 43 others from the same source and published within six weeks on either side of this one. This one is in the 32nd percentile – i.e., 32% of its contemporaries scored the same or lower than it.
