Ecomorphological trends in the Artedidraconidae (Pisces: Perciformes: Notothenioidei) of the Weddell Sea

Abstract: An ecomorphological study was performed on ten species of the family Artedidraconidae, the most benthic of the suborder Notothenioidei. These species are sympatric on the shelf of the Weddell Sea. The results show that the four genera comprising the family (Artedidraco, Dolloidraco, Histiodraco and Pogonophryne) can be differentiated by just a few morphometric features of their sensory organs and mouth. The genera were also clearly defined by the composition of their diet (benthic and epibenthic), the size of … Show more

“…In another Notothenioid family, the artedidraconids, an inverse relationship was observed between the size of the sagitta and that of the eye. This may indicate an increase in auditory capacity and non-visual sensory capability as visual capability decreases (Lombarte et al 2003) as occurs in species that live over the sea bottom and not in the water column (Lombarte and Cruz 2007;Volpedo et al 2008).…”

“…Major disturbance within an aquatic ecosystem can result in a shift in fish community structure (Olden et al 2008;Villéger et al 2010). The morphological differences between species are indicative of differences in ecological strategies (Norton et al 1995) in relation to locomotion (Fulton et al 2001;Wainwright et al 2002), habitat use (Gatz 1979;Winemiller 1991;Lombarte et al 2003;Lombarte et al 2010) and feeding strategies Wainwright and Richard 1995;Pouilly et al 2003; Barnett et al 2006;Wagner et al 2009). …”

“…This has led to the concept of ecomorphology, which defines a community or species assemblage through a morphospace determined by the morphological data of the species that comprise that assemblage (Karr and James 1975;Gatz 1979;Bock 1990;Lombarte et al 2003). Morphospaces can be analysed using geometric morphological methods (Neige 2003;Antonucci et al 2009), from which an ecomorphological diversity index (EMI) can be generated (Recasens et al 2006) to provide additional information on the morpho-functional structure of the community (Winemiller 1991;Fulton et al 2001;Mason et al 2007).…”

“…Even though sensory modalities underlying spatial segregation phenomena have previously been highly documented in fish (Aguirre & Lombarte 2000, Bozzano & Catalán 2002, Lombarte et al 2003, Sabatés et al 2003, Schulz-Mirbach et al 2008, Seehausen et al 2008, there is still scant information on the role played by sensory modalities in relation to temporal segregation. Additionally, although the survival of a species demands some co-evolution of its sensory systems, adaptation to a temporal niche causes implementation of compensatory mechanisms that counterbalance the quality of each sensory modality, which means that the poor performance of one system is compensated for by the good performance of another (Schellart & Popper 1992).…”
