Zenopontonia soror (Nobili, 1904) (Caridea: Palaemonidae) is a shrimp symbiont of several sea star species that exhibits homochromy with distinct mimetic coloration according to host species. To date, populations of Z. soror have been studied extensively in the Indo-Pacific and Gulf of Panama; however, those present in the Gulf of California (Mexico) have not been evaluated. Here we conduct the first

Limited population genetic structure in the littoral gastropod Nerita tessellata (Neritimorpha, Neritidae) suggests high dispersal across the Caribbean Sea J. Exp. Mar. Biol. Ecol. (IF 2.0) Pub Date : 2023-08-27 Julian F. Quintero-Galvis, Korina Ocampo-Zuleta, Lyda R. Castro, Juan Carlos Narváez-Barandica
The Caribbean Sea is characterized by an incredible biodiversity, including several endemic mollusk species, most of which have larval dispersal as their main mechanism of gene flow. It is known that the present-day population structure of a species reflects the combination of oceanographic currents, life-history traits, and historical events. Nerita tessellata is a common gastropod species in coastal

Selective pressure on ontogenic stages of blue mussels (Mytilus edulis, L.) J. Exp. Mar. Biol. Ecol. (IF 2.0) Pub Date : 2023-08-26 Efflam Guillou, Thibault Androuin, Nicolas Toupoint, Réjean Tremblay
Our previous work confirmed that the higher survival, growth, and commercial performance of a mussel stock collected from a specific lagoon have been maintained over the last 25 years at a microgeographic scale despite intensive transfers of its spat to other local mussel sites. The objective of this study was to identify potential selection mechanisms supporting the quality of this stock. We used

Factors affecting biphasic degradation of eDNA released by Japanese jack mackerel (Trachurus japonicus) J. Exp. Mar. Biol. Ecol. (IF 2.0) Pub Date : 2023-08-26 Toshiaki S. Jo
Understanding environmental DNA (eDNA) persistence and degradation processes is necessary for the precise assessment of species distribution and abundance in marine environments via eDNA. Given the various particle sizes and persistence states of eDNA in water, biphasic degradation of eDNA, composed of its initial rapid and subsequent slower decay, may describe the fate of eDNA more precisely than

Labral tooth loss in the carnivorous gastropod Acanthina monodon: Recovery capacity and incidence in the feeding process J. Exp. Mar. Biol. Ecol. (IF 2.0) Pub Date : 2023-08-25 J.A. Büchner-Miranda, H.N. Jaramillo, L.P. Salas-Yanquin, F. Márquez, A. Averbuj, M.S. Zabala, F.J. Paredes-Molina, V.M. Cubillos, O.R. Chaparro
The temporary loss of an animal feeding structure can often be replaced by a new one. During that replacement period, however, the animal can be limited in its ability to feed. The muricid gastropod Acanthina monodon can sometimes lose its labral tooth naturally; recovering the tooth will typically take between 14 and 21 days. Our studies show that the volume, length and area of the recovered tooth

Zooplankton derived organic matter as a food source for benthic coral J. Exp. Mar. Biol. Ecol. (IF 2.0) Pub Date : 2023-08-22 Jaclyn F. Torkelson, Jesse B. Crandall, Mark A. Teece
Zooplankton derived organic matter, such as fecal pellets and carcasses, may be a vital source of nutrients for benthic corals. In shallow tropical reefs, settling particles (organic matter) often reach the benthos, in contrast with deeper systems where the particles are recycled/transformed prior to reaching the benthos. Furthermore, zooplankton fecal pellets aggregate together and entrain additional

Burrowing crabs' influence on tidal marsh vegetation species composition and abundance in a temperate back-barrier marsh, Cape Cod, Massachusetts, USA J. Exp. Mar. Biol. Ecol. (IF 2.0) Pub Date : 2023-08-08 Megan C. Tyrrell, Sofi Courtney, Emily Brown, Christian von Sperber
Emergent vegetation in coastal marshes across the Northeastern United States have been declining and changing in relative species composition due to abiotic factors such as accelerated sea level rise, storm intensity, excess nutrients, and other anthropogenic disturbances. A possible biotic factor in marsh decline is increased perturbation from burrowing crabs. Uca pugilator and Minuca pugnax (fiddler

The roles of heating rate, intensity, and duration on the response of corals and their endosymbiotic algae to thermal stress J. Exp. Mar. Biol. Ecol. (IF 2.0) Pub Date : 2023-07-21 Nicolas R. Evensen, Timothy G. Bateman, Courtney N. Klepac, Sebastian Schmidt-Roach, Marcelle Barreto, Manuel Aranda, Mark E. Warner, Daniel J. Barshis
Anthropogenic ocean warming is one of the biggest threats to marine organisms worldwide. However, it remains unclear how the duration and intensity of thermal anomalies affect organismal stress responses and thermal thresholds. We used detailed tracking of coral endosymbiont and host physiology and dose-response analyses to compare the effects of multiple heating rates, intensities, and exposure durations

Discriminating the effects of bioturbation and herbivory by the intertidal burrowing crab Neohelice granulata on microphytobenthic assemblages of SW Atlantic mudflats J. Exp. Mar. Biol. Ecol. (IF 2.0) Pub Date : 2023-07-19
In shallow soft-bottom intertidal systems, microphytobenthic assemblages (MPB) and macrofauna interact and play important roles in ecosystem functioning. Macrofauna can affect MPB through bioturbation or/and herbivory. Most bioturbators also exert herbivory pressure on MPB, hence the results of the interaction between benthic macrofauna and MPB is not easy to predict. In this study we performed a small
