“…Family patterns-The families best represented in the study area during 1998, 2003 and 2018 were Spionidae, Ampharetidae and Cirratulidae. These families are characterized as being indicators of environmental stress associated with areas of high organic matter (Bellan et al 1988;Hale & Heltshe 2008;Ranasinghe et al 2010), and previously were reported with high abundances in the study area by Rodriguez-Villanueva et al (2000). The family Ampharetidae has been considered tolerant in high concentrations of Cu (Bryan & Gibbs 1987;Dean 2008), and this tolerance may explain the high abundance of these organisms registered for 2018 in areas near the wastewater treatment plants.…”

The aim of this study was to describe and analyze the structure, distribution, and temporal variation in the composition of benthic polychaeta and their relation to abiotic characteristics in marine sediments along the continental shelf of Bahia de Todos Santos, Baja California, Mexico. Benthic macrofauna and environmental variables were collected to coordinated with a long-term ocean monitoring project known as the Southern California Bight Regional Monitoring Program. A total of nineteen stations were collected in September 1998, twenty stations in November 2003, fifteen stations in December 2013 and sixteen stations in September 2018. These data were compared to assess the response of benthic polychaete assemblages to natural and human induced changes in sediment characteristics. All stations were sampled using a Van Veen grab (0.1 m2) at depths between 15 to 206 m. Sites were selected using a multiple density nested random-tessellation stratified design. Environmental parameters measured included depth (m), sediment grain size <63µm (%), organic carbon (%), and concentration of metals: Co, Cd, Cr, Cu, Fe, Mn, Ni, Pb, and Zn. A total of 11,854 polychaetous annelids were identified in 43 families, with the numerically dominant families for all years (Spionidae, Chaetopteridae, Cirratulidae, Maldanidae, Onuphidae, and Ampharetidae) accounting for 52.95% of individuals. The best represented families in 1998 were Spionidae, Maldanidae, Ampharetidae and Cirratulidae. In 2003 the best represented families were Spionidae, Maldanidae, Cirratulidae, and Onuphidae; in 2013 Chaetopteridae and Spionidae; and in 2018 Spionidae, Ampharetidae, Syllidae and Cirratulidae. The Bio-Env multivariate analysis showed that the factors that most correlated with the abundance and richness of families and had the greatest influence over spatial distribution trends for community structure were %Organic carbon and Cu concentration during 1998, % Organic carbon and depth in 2003 and Pb concentration in 2013.

“…Significant quantities of trace metals and other pollutants are emitted into the atmosphere daily, followed by deposition in the water column, rapid removal and transportation to bottom sediments (Chong & Wang, 2000; Schiff et al , 2000; Sabin et al , 2005; Castro-Morales et al , 2014; Macías-Zamora et al , 2014a, 2016). These anthropogenic contaminants may accumulate in sediments of nearshore coastal regions causing habitat alteration and thus changes in community composition, abundance and diversity of benthic fauna (Lenihan et al , 2003; Ranasinghe et al , 2003, 2007, 2012).…”

A temporal analysis of the benthic polychaete community and its relationship with environmental variables was conducted by comparing coastal sediment samples collected in three separate sampling events between 1998 and 2013 from the southern end of the Southern California Bight (SCB). Environmental variables indicated a spatio-temporal increase of the sand fraction in sediment composition. Station stratification by depth from shallow to deep, and a reduction of trace metal enrichment (Co, Cr, Cu, Mn, Ni, Pb and Zn) was also found. There was a notable change in polychaete family composition due to high abundances and frequency of Spionidae, Chaetopteridae and Phyllodocidae in 2013, especially close to the Binational wastewater treatment plant discharge. An increase in polychaete abundance, richness and diversity was indicative of a probable relationship with regional weather conditions (El Niño-Southern Oscillation and recent drought events during sampling) along with local anthropogenic discharges of wastewater treatment plants in the area.

“…A key component of these programs is documenting changes in bottom dwelling invertebrate communities over space and time. In the SCB these include long-term localized programs conducted by four major wastewater discharge agencies (see City of San Diego 2018 ; Los Angeles County Sanitation Districts 2020; City of Los Angeles 2021 ; Orange County Sanitation District 2022 ), as well as broader regional programs that have been conducted every 4 or 5 years since 1994 (e.g., Allen et al 1998 , 2002 , 2007 , 2011 ; Bergen et al 1998 ; Ranasinghe et al 2003 , 2007 , 2012 ; Gillett et al 2017 , 2022 ; Walther et al 2017 ; Wisenbaker et al 2021 ). Key to the success of these and other programs and surveys is assuring taxonomic standardization of the resultant macroinvertebrate data sets.…”

The isopod crustaceans reported from or expected to occur in littoral and sublittoral marine habitats of the Southern California Bight (SCB) in the northeastern Pacific Ocean are reviewed. A total of 190 species, representing 105 genera in 42 families and six suborders are covered. Approximately 84% of these isopods represent described species with the remaining 16% comprising well-documented “provisional” but undescribed species. Cymothoida and Asellota are the most diverse of the six suborders, accounting for ca. 36% and 29% of the species, respectively. Valvifera and Sphaeromatidea are the next most speciose suborders with between 13–15% of the species each, while the suborder Limnorioidea represents fewer than 2% of the SCB isopod fauna. Finally, the mostly terrestrial suborder Oniscidea accounts for ca. 5% of the species treated herein, each which occurs at or above the high tide mark in intertidal habitats. A key to the suborders and superfamilies is presented followed by nine keys to the SCB species within each of the resultant groups. Figures are provided for most species. Bathymetric range, geographic distribution, type locality, habitat, body size, and a comprehensive list of references are included for most species.
