“…Centroids of Sargassum muticum (asterisk), Bifurcaria bifurcata (filled triangle), and Saccorhiza polyschides (filled square) had the largest number of individuals, whereas B. bifurcata had the greatest diversity. Several studies have pointed out that number of individuals and identity of species in epifaunal assemblages are related to morphology and/or structural complexity of macroalgae (Taylor and Cole 1994;Wernberg et al 2004;McDonald and Bingham 2010). Here, the fact that the number of individuals was larger in S. polyschides could be in part due to the complex structure of S. polyschides holdfast.…”

“…For example, the larger abundance of isopods and amphipods in S. muticum might respond to certain mechanism of host selection, because many species of these groups remain in constant contact with surfaces and associate preferentially with microhabitats that closely match their body size (Viejo 1999;Parker et al 2001). Nevertheless, this assumption has to been taken with caution, because in marine habitats small herbivores tend to be generalists and very few species are host plant specialists (Hay and Steinberg 1992;McDonald and Bingham 2010).…”

“…For example, certain crustaceans are more abundant in branched macroalgae than in macroalgae with a foliose morphology (McDonald and Bingham 2010). B. bifurcata and S. muticum have similar morphology in comparison with S. polyschides, and thus, we could expect that epifaunal assemblages associated with these species were more similar.…”

Effects of macroalgal identity on epifaunal assemblages: native species versus the invasive species Sargassum muticum

Seaweeds are a refuge from stressful conditions associated with life on rocky intertidal shores, and there is evidence that different macrophytes support different assemblages of mobile epifauna. Introduction of nonindigenous macroalgae may have a great impact on associated epifaunal assemblages and ecosystem processes in coastal areas. Previous studies have reported conflicting evidences for the ability of epifauna to colonize nonindigenous species. Here, we analyzed epifaunal assemblages associated with three species of macroalgae that are very abundant on intertidal shores along the Galician coast: the two native species Bifurcaria bifurcata and Saccorhiza polyschides and the invasive species Sargassum muticum. We collected samples of each species from three different sites at three different times to test whether variability of epifaunal assemblages was consistent over space and time. Epifaunal assemblages differed between the three macroalgae. Results suggested that stability and morphology of habitat played an important role in shaping the structure of epifaunal assemblages. This study also showed that the invasive S. muticum offered a suitable habitat for many invertebrates.

“…Different epifauna communities on different macrophyte species have often been attributed to habitat complexity structure (Veiga et al, , ). Previous studies have demonstrated that increased abundance and diversity of species are associated with more morphologically complex habitat‐forming macrophytes (McDonald & Bingham, ; Png‐Gonzalez, Vázquez‐Luis, & Tuya, ; Sueiro, Bortolus, & Schwindt, ; Veiga et al, , ). This is essentially due to the increase in interstitial habitable space with a range of ecological niches for colonisation, and the reduction in the foraging effectiveness of predators (Cacabelos et al, ; Hooper & Davenport, ; Png‐Gonzalez et al, ; Sueiro et al, ).…”

“…Hence, both habitat identity and complexity represent substantial criteria of habitat selection or choice by grazers and from which an organism can develop its host specificity. Nevertheless, small herbivorous animals in marine ecosystems/habitats tend to be generalists and very few species are host plant specific/specialists (McDonald & Bingham, ). Based upon the epifauna diet, most species found during this study consisted of herbivores capable of using several ecological niches.…”

The introduction of Sargassum muticum modifies epifaunal patterns in a Moroccan seagrass meadow

et al. 2018

Marine macrophytes sustain valuable epiphytic biodiversity. Nonindigenous macroalgae may induce changes in composition and structure of epifaunal assemblages and therefore support different assemblages from those associated with native species. In this study, differences in faunal community structure between the introduced fucoid Sargassum muticum and the native seagrass Cymodocea nodosa were tested over a year on an intertidal shallow sandy bottom at the southern introduction front, the El Jadida coastline (NW Morocco). Epifaunal community structure consistently differed between macrophytes through seasons, with more species‐rich assemblages associated with S. muticum than C. nodosa despite comparable abundances. The significantly greater epifauna diversity on S. muticum may be related to its structural complexity. However, the species contributing most to differences in assemblages between both macrophytes, such as Steromphala umbilicalis and S. pennanti, were found on both habitats with temporally varying abundances. Some species‐specific affinities were detected (Stenosoma cf. acuminatum, Elasmopus vachoni, Chauvetia brunnea). Nitrogen, dissolved oxygen, suspended matter and temperature were identified as the best explanatory variables contributing to the observed macroepifaunal patterns. This study provides evidence that S. muticum acts as a favourable and additional habitat for epifaunal species and supports a more diverse epifaunal assemblage in this Moroccan seagrass meadow.

Social Recognition in Invertebrates

View full text Add to dashboard Cite

Social recognition is regarded as a key element in life of many organisms, where it can play an essential role in the structure and stability of a number of behavioural networks, such as dominance hierarchies, territorial defence, competitive aggression, pair bonds, mate selection, and kin favouritism. The skill for sophisticated and flexible recognition-as for cognitive abilities-has been known for a very long time in vertebrates, particularly in mammals, who are the most closely related to humans and from which there is an expectation to provide some insights for human evolution, being their behaviour easily recognized. However, as evidenced by the growing number of studies and reports, there is an increasing scientific interest in the occurrence and properties of this ability in invertebrates where, however, it may not be so easily and clearly identified. The possible presence of individual recognition as well as the communication media and cues involved in social recognition is the prevalent topic of recent studies, indicating that invertebrates can possess refined recognition systems and that, regardless of their taxonomic status, many animals show sophisticated recognition abilities. The present book offers a compendium of the most recent advances of social recognition in invertebrates, dealing with several behaviours involved in this recognition as cooperative behaviour, parental care, mating and aggressive relationships.Among invertebrates, eusocial insects (ants, wasps, termites and bees) represent the most fascinating examples of cooperative group living and surely the most studied since 1950s for the evolution of cooperative behaviour and recognition systems. The incredible organization of a social insect colony is based on the ability to recognize and assign individual membership to a particular and relevant class, such as caste, dominance status and gender, and on the discrimination between nestmates from non-nestmates (reviewed in this volume by Bagnères and Hanus; Breed et al.; Cervo et al.). The ontogeny of this nestmate recognition is a still open and fascinating field: according to Signorotti et al. (this volume), wasps and bees
