“…Here, we examined the physical geometry of the mussel matrices and their associated benthic macro‐scale communities across a broad ecoregional scale in an effort to better understand the characteristics of mussel matrices, particularly when attempting to predict patterns in diversity. It has been suggested that environmental factors often play a role in the abundance and presence of certain species, and because the marine ecoregions are partly defined by local conditions (Ibanez‐Erquiaga et al, 2018; Valqui et al, 2021), “ecoregions” as random effects were incorporated into the modelling analysis. Therefore, our results support small‐scale experimental results which show that mussel bed complexity is an important factor in determining species composition and abundance (Koivisto & Westerbom, 2010).…”

“…El Niño events can induce shifts in the distribution ranges of sea slugs ( Goddard et al 2018 ) and even result in species turnover ( Valqui et al 2021 ). During strong El Niño events, it is noteworthy that mollusk species endemic to tropical areas have been observed in Peruvian waters due to the displacement of warm-water masses ( Velez and Zeballos 1985 ; Paredes et al 1998 ; Ramírez et al 2003 ).…”

Nudibranchs, as a group, have received limited attention in terms of scientific study along the coastline of Peru. Here, an updated and comprehensive list of nudibranch species found in the Peruvian sea is presented, compiled through an extensive review of relevant literature. This compilation encompasses a total of 31 species, classified into two suborders, 10 superfamilies, 20 families, and 28 genera. With respect to the biogeographic provinces along the Peruvian coast, 23 species inhabit the Warm Temperate Southeastern Pacific province, 18 species occur in the Tropical Eastern Pacific province, and 10 species are found in both provinces, crossing the transitional zone between them. In terms of distribution patterns, two species exhibit a cosmopolitan distribution (Glaucus atlanticus and Fiona pinnata), while two species display a circumtropical distribution (Cephalopyge trematoides and Phylliroe bucephala). One species exhibits a bipolar distribution in the Eastern Pacific and possesses an amphi-South American distribution (Rostanga pulchra). Additionally, six species exhibit an amphi-South American distribution (Rostanga pulchra, Diaulula punctuolata, Doto uva, Tyrinna evelinae, Tyrinna delicata, and Doris fontainii), and two species are endemic to Peru (Corambe mancorensis and Felimare sechurana). This study provides comprehensive information on biogeographical aspects, geographical distributions, and taxonomic updates within the nudibranch species documented in Peru. Furthermore, we discuss the status of species listed in previous literature that have not been confirmed by collections, referring to them as potentially occurring species.

“…Critically less documented, the potential effects of large-scale ocean-atmosphere fluctuations such as EN are poorly known in Peru, despite being a recurrent event. Recent results suggest diverse ecological responses associated with a significant reduction in the latitudinal distribution range in P. pluvia during the 2015 and 2017 EN events, whereas P. clematis exhibited an expansion southward (Valqui et al ., 2021). However, intrinsic biological responses are complex and depend on the degree of adaptability, thermal tolerance, and feeding habits, among other physiological and ecological aspects.…”

“…In addition, the establishment of P. clematis in the lower intertidal zones as a co-dominant species after EN events (1982/83 and 1997/98) has been documented along the northern Chilean coast (Rivadeneira, 1998, as cited in Rivadeneira & Oliva, 2001). The anemone P. clematis seems to be a resistant and opportunistic species amidst disturbances in its environment, as there is also evidence of being ubiquitous along the Peruvian coast during EN conditions (Valqui et al ., 2021). Nevertheless, long-term records of benthic rocky intertidal communities are needed to observe changes attributed to EN events and to have accurate insights concerning benthic responses.…”

Diverse and abundant sea anemones are common in shallow marine areas. Detailed biodiversity analysis in Peru are comparatively scarce. To contribute to the biodiversity inventory and distribution information of this taxa, we analyzed exhaustively the available bibliography in Peruvian waters. A total of 23 anemone species were identified, distributed in 68 localities, and grouped into 1 Order (Actiniaria), 6 Families (Actiniidae, Actinostolidae, Aiptasiidae, Isanthidae, Phelliidae and Sagartiidae) and 20 Genera. The most reported species are Anthothoe chilensis (37 references), Phymactis clematis (28), Phymanthea pluvia (27), Oulactis concinnata (18), and Antholoba achates (15). Lima is the region with the highest number of publications, followed by La Libertad, Piura, Lambayeque, and Ancash. Anthothoe chilensis occurs in almost all the Peruvian coastal regions. On the contrary, O. concinnata has been primarily observed in Lima, while A. achates occurred only in the southern regions (Ica, Arequipa, and Moquegua). Rocky substrates (~55% records) seem to be the most suitable habitat for sea anemones in Peru, corresponding to exposed (e.g. vertical walls) and sheltered zones (e.g. rocky crevices, caves, under rock areas). Although most of the species in Peru exhibit a relatively wide spatial distribution, our results suggest that there are several regions with little or no research efforts. Despite a growing study effort over the past 30 years (>50% of biodiversity reported), the current biodiversity status for this group is still unclear. A significant effort is needed to better analyze occurrence patterns and unveil new species regarding a changing environmental scenario with human influence.
