Abstract

While horseshoe crabs Limulus polyphemus from regions with two daily tides express endogenous circatidal (~ 12.4 h) activity rhythms, much less is known about locomotor rhythm expression in horseshoe crabs from other tidal regimes. This study investigated whether horseshoe crabs (1) always express activity rhythms consistent with their natural tides, and (2) can alter activity rhythm expression in response to novel tide cycles. Activity rhythms of animals from environments with two daily tides (Gulf of Maine, 43°6' N/70°52' W, and Massachusetts, 41°32' N/70°40'W), one dominant daily tide (Apalachee Bay, Florida, 29°58' N/84°20' W), and microtides (Indian River Lagoon, Florida, 28°5' N/80°35' W) were recorded in 2011-2013 during three artificial tide conditions: no tides, a 12.4 h tidal cycle, and a 24.8 h tidal cycle. Interestingly, L. polyphemus from the microtidal site (n = 7) appeared "plastic" in their responses; they were able to express both bimodal and unimodal rhythms in response to different tide cycles. In contrast, the other two populations exhibited more fixed responses: regardless of the tides they were exposed to, animals from areas with one dominant daily tide (n = 18) consistently expressed unimodal rhythms, while those from areas with two daily tides (n = 28) generally expressed bimodal rhythms. Rhythms expressed by L. polyphemus thus appear to be a function of endogenous clocks, the tidal cues to which animals are exposed, and tidal cues that animals experience throughout ontogeny.

Attention Score in Context

This research output has an Altmetric Attention Score of 1. 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 21 October 2017.
All research outputs
#10,662,442
of 12,022,940 outputs
Outputs from Marine Biology
#1,812
of 1,979 outputs
Outputs of similar age
#238,952
of 284,783 outputs
Outputs of similar age from Marine Biology
#41
of 42 outputs
Altmetric has tracked 12,022,940 research outputs across all sources so far. This one is in the 1st percentile – i.e., 1% of other outputs scored the same or lower than it.
So far Altmetric has tracked 1,979 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 5.8. This one is in the 1st percentile – i.e., 1% 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 284,783 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 42 others from the same source and published within six weeks on either side of this one. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
