One large colony of Alcyonidium albescens on left side (arrow).

Figure 2 in Ectosymbionts of the non-indigenous Asian shore crab, Hemigrapsus sanguineus (Decapoda: Varunidae), in the western north Atlantic, and a search for its parasites
Figure 2. Ventral view of Hemigrapsus sanguineus female (26.1 mm CW; same crab as Figure 1B) with a gaping abdomen caused by the accumulation of young blue mussels Mytilus edulis attached to the pleopods (white arrow shows largest mussel, 9.5 mm long). Colonies of the calcareous bryozoan Conopeum tenuissimum present on many of the pereopods. Black arrow points to the polychaete Spirorbis sp.
Figure 4 in Ectosymbionts of the non-indigenous Asian shore crab, Hemigrapsus sanguineus (Decapoda: Varunidae), in the western north Atlantic, and a search for its parasites
Figure 4. Percentages of colonies of Conopeum tenuissimum at various locations on the carapace of Hemigrapsus sanguineus based on 336 colonies from 134 crabs (Table III) collected 29 March 2006 and 26 April 2006 at Townsends Inlet. Anterolaterally are hepatic areas, posterolaterally are branchial areas; numbers in parentheses are for colonies that span the hepatic-branchial regions. Medially from anterior to posterior are frontal, progastric, mesogastric, cardiac, and intestinal locations.
Figure 1 in Ectosymbionts of the non-indigenous Asian shore crab, Hemigrapsus sanguineus (Decapoda: Varunidae), in the western north Atlantic, and a search for its parasites
Figure 1. Dorsal views of Hemigrapsus sanguineus with colonies of Conopeum tenuissimum and other ectosymbionts, collected intertidally in New Jersey. (A) Female (27.4 mm CW; first left walking leg missing) with several colonies on the carapace and on the pereopods. Arrow shows a large colony of Alcyonidium albescens covering the left posterior quadrant of the carapace. (B) Female (26.1 mm CW; same crab with mussels under abdomen, Figure 2) showing Conopeum tenuissimum colony spanning the left hepatic-branchial region of the carapace, a small medial colony and a colony in the right hepatic region, plus numerous colonies on the pereopods. (C) Male (18.5 mm CW) with a single colony of Conopeum tenuissimum covering more than half of the carapace, with some smaller colonies on the pereopods. (D) Female (24.9 mm CW; left cheliped missing) with four colonies of Conopeum tenuissimum on the carapace, two in hepatic and two in branchial areas. Barnacle is Semibalanus balanoides.
Detecting regenerating limbs in Hemigrapsus sanguineus based on limb mass
<ol> <li><span>Regeneration of lost appendages is a gradual process in many species, spreading energetic costs of regeneration through time. Energy allocated to regeneration of lost appendages cannot be used for other purposes and therefore commonly elicits energetic trade-offs in biological processes. </span></li> <li><span>We used limb loss in the Asian shore crab <em>Hemigrapsus</em> <em>sanguineus</em> to compare the strength of energetic trade-offs resulting from historic limb losses that have been partially regenerated versus current injuries that have not yet been repaired. Consistent with previous studies, we show that limb loss and regeneration results in trade-offs that reduce reproduction, energy storage, and growth. </span></li> <li><span>As may be expected, we show that trade-offs in these metrics from historic limb losses far outweigh trade-offs from current limb losses, and correlate directly with the degree of historic limb loss that has been regenerated. </span></li> <li><span>As regenerating limbs get closer to their normal size, these historical injuries get harder to detect, despite the continued allocation of additional resources to limb development. Our results demonstrate the importance of a method for identifying historic appendage losses and of quantifying the amount of regeneration that has already occurred, as opposed to assessing only current injury, to accurately assess the strength of energetic trade-offs in animals recovering from non-lethal injury.</span></li> </ol>

Morphometric correlations between dietary and reproductive traits of two brachyuran crabs, Hemigrapsus sanguineus and Aratus pisonii
<p>Many animals have flexible morphological traits that allow them to succeed in differing circumstances with differing diets available to them. For brachyuran crabs, claw height and gut size are diet-specific and largely reflect foraging strategies, while abdomen width reflects relative levels of fecundity. However, the link between claw size and diet has largely been documented only for primarily carnivorous crabs, while the link between diet and fecundity is strong in herbivorous crabs. We sought to determine the nature of the intraspecific relationship between claw size, dietary habits, and fecundity for two primarily herbivorous crab species, <em>Hemigrapsus</em> <em>sanguineus</em> and <em>Aratus</em> <em>pisonii</em>. Specifically, we examined whether claw size and/or abdomen width can be used as reliable measures of individual diet strategy. To test these hypotheses, we collected crabs and measured the dimensions of their claws, abdomens, and guts. By comparing these dimensions for each individual, we found that strongly predictive relationships do not exist between these traits for the primarily herbivorous species in our study. Thus, identifying external morphological features that can be used to assess diets of primarily herbivorous crabs remains elusive.</p>

Aerial metabolic rates of the Asian shore crab Hemigrapsus sanguineus
<p>Rapid warming in the Gulf of Maine may influence the success or invasiveness of the Asian shore crab, <em>Hemigrapsus sanguineus</em>. To better predict the effects of climate change on this invasive species, it is necessary to measure its energy dynamics under a range of conditions. However, previous research has only focused on the metabolism of this intertidal species in water. We sampled adult crabs from three different sites and measured their metabolic rates in air. We show that metabolic rate increases with body mass and the number of missing limbs, but decreases with the number of regenerating limbs, possibly reflecting the timing of energy allocation to limb regeneration. Importantly, metabolic rates measured here in air are ~4× higher than metabolic rates previously measured for this species in water. Our results provide baseline measurements of aerial metabolic rates across body sizes, which may be affected by climate change. With a better understanding of respiration in <em>H. sanguineus</em>, we can make more informed predictions about the combined effects of climate change and invasive species on the northeast coasts of North America.</p>
