Coastal fish assemblages and predation pressure in northern-central Chilean Lessonia trabeculata kelp forests and barren grounds

Abstract: Kelp forests are declining in many parts of the globe, which can lead to the spreading of barren grounds. Increased abundances of grazers, mainly due to reduction of their predators, are among the causes of this development. Here, we compared the species richness (SR), frequency of occurrence (FO), and maximum abundance (MaxN) of predatory fish and their predation pressure between kelp forest and barren ground habitats of northern-central Chile. Sampling was done using baited underwater cameras with vertical a… Show more

“…(2020), different colour morphs of S. viridis have been observed together inhabiting the same environments. This colour polymorphism could thus be related to either juvenile stages or microhabitat preferences as both colour morphs are associated with algae (Pérez‐Matus et al ., 2017a; Riquelme‐Pérez et al ., 2019). This study also allowed the authors to depict the evolutionary history of the Scartichthys genus.…”

“…In addition, they are known among local fishermen as “borrachillas” (drunk) because the consumption of the flesh of these fish leads to a sleepy or drunk feeling (Méndez‐Abarca & Mundaca, 2016; Williams, 1990). Despite these interesting aspects of their ecology, Scartichthys blenniids remain difficult (Pérez‐Matus et al ., 2007; Riquelme‐Pérez et al ., 2019) or even impossible to identify at the species level in the field (Villegas et al ., 2019). Identification is especially challenging across the 6000 km where three recognized species are known to occur in sympatry.…”

“…In line with Gaither et al (2020), different colour morphs of S. viridis have been observed together inhabiting the same environments. This colour polymorphism could thus be related to either juvenile stages or microhabitat preferences as both colour morphs are associated with algae (Prez-Matus et al, 2017;Riquelme-Prez et al, 2019).…”

“…Alternatively, epifaunal invertebrates may avoid the basal sections of large kelp thalli to escape intense predation from benthic predators. Demersal fishes prey intensively on benthic invertebrates in kelp forests of northern-central Chile [44]. Accordingly, the nest-building amphipod S. femorata predominantly lives on the apical blades of giant kelp M. pyrifera where the amphipods suffer less predation than on basal blades [45].…”
