“…Previous records on species of the genera Leucothoe and Caprella are documented, either in the descriptions of amphipods or unintentionally photographed (e.g., [50], see Figures 5 and 6 in [51]). As benthic amphipods can be associated with other sessile fauna (like in this case) or macroalgae [52], they are susceptible for colonisation by motile diatom species (e.g., Navicula spp.) or even sedentary species (e.g., Tabularia spp., Licmophora spp.)…”

Epibiotic associations can result in co-introductions of non-indigenous species, which may affect ecosystems in several ways. In fouling communities of three estuaries in southern Brazil, a number of amphipods was found to harbour a dense coverage of epibionts. Three different species, the two globally widespread caprellids Caprella equilibra and Paracaprella pusilla, as well as the ischyrocerid Jassa valida, had been colonised by diatoms. Further scanning electron microscope analyses assigned these diatoms to 14 different species that had previously been reported from benthic habitats. This is one of the scarce records of diatoms attached to amphipods. The occurrence of the diatom Amphora helenensis represents the first report for Brazilian waters as well as the second record for the whole SW Atlantic Ocean. As some diatoms were associated with common fouling amphipods, a possible regional spread aided by these crustaceans seems likely. Possible effects of this amphipod-diatom association on the animals and their implications for the underlying ecosystems of this remain to be elucidated.

“…Amphipods exploit these two functions provided by seaweeds (refuge and food) and constantly evaluate them under the current circumstances (Martínez-Laiz et al, 2018;Wernberg et al, 2013). This is especially important for tubular amphipods, such as the studied species (A. marcuzzii), as they usually feed on the seaweed in which they build their tubes and move little from their seaweed hosts.…”

“…However, the wide diversity of seaweed morphologies (foliose, branched, calcareous, etc.) and chemical compositions (the stoichiometric ratio or the fixed proportions of elements, secondary metabolites, and among others) affect food quality for these types of herbivores (Demko et al, 2017;Hay, 1997;Martínez-Laiz et al, 2018;O'Brien & Scheibling, 2016).…”

Food source or refuge: What is behind amphipod choices for seaweeds?

et al. 2021

Seaweeds are important structuring components of coastal communities, as they are among the main primary producers in the trophic food web of coastal zones and are home to several associated organisms from all trophic levels (producers, consumers, and decomposers) (De Oliveira et al., 2016;Muguerza et al., 2020). In the coastal zones, both seaweeds and their associated fauna are under abiotic pressure (wave action, temperature, salinity, desiccation, and among others) and biotic pressure (predation and competition).

“…This suggests a directional migration from their habitat of emergence towards rocky areas at night and a return trip at dawn to take shelter in sandy bottoms. Many amphipod species have clear habitat preferences and show active host selection when dispersing (Poore et al ., 2000; Poore, 2005; Mártinez-Laiz et al ., 2018). Migrant amphipods from adjacent sandy biotopes have also been collected above meadows of Posidonia oceanica (Linnaeus) Delile, 1813 (Michel, 2011); light traps deployed on this habitat provide exclusive species (e.g.…”

“…In addition, amphipods can exhibit very specific substrate preferences and their habitat distribution is relatively well-known (e.g. Guerra-García, 2001; Gestoso et al ., 2012; Martínez-Laiz et al ., 2018). Thus, we expect to reveal complex and specific responses, as well as determining the emergence habitat of species.…”

Demersal amphipod migrations: spatial patterns in marine shallow waters

2020

The nocturnal displacement to the water column of species hiding in the substrate during the day (so-called demersal migration) is a widespread phenomenon in coastal habitats. However, despite the relevance of these migrations to coastal ecosystem functioning, most of their ecological aspects are poorly understood. We aim to characterize spatial distribution patterns of demersal amphipods by comparing samples collected by light traps deployed both at rocky and nearby sandy areas. Dispersal abilities of such species were explored by considering two spatial scales of separation between rocky and sandy substrates: (1) <100 m and (2) >1 km. A total of >45,000 amphipod specimens were collected in the water column during the whole study, belonging to 50 species. The numerically dominant species were Guernea coalita, Bathyporeia cf. elegans, Perioculodes longimanus and Nototropis swammerdamei. The present study highlights the relevance of substrate type and study location on coastal demersal amphipod migrations. Amphipod assemblages were significantly different in the water column above rocky and sandy bottoms, even at a small spatial scale. Species emerging from rocky bottoms tend to remain in the proximity of this habitat; they showed lower abundances in sandy areas located nearby and almost none of them reached distant sandy areas. In contrast, migrant species commonly found on sediment during the day were collected at higher abundances in light traps deployed above rocky bottoms. Although several factors (e.g. food availability, predation pressure) are proposed to explain these patterns, the purpose of this horizontal migration remains unknown.
