“…For a large number of taxa these boundaries were characterized by pronounced changes in the oceanographic features of the waters (e.g. The location, oceanographic characteristics, and changes in fauna at certain boundaries between provinces have been described by many researchers in studies both regional (Gordon & Duncan, 1985;Macpherson, 1991;Gomes, Haedrich & Villagarcia, 1995;Mahon et al, 1998;Bergstad, Bjelland & Gordon, 1999;Williams, Koslow & Last, 2001;Abello, Carbonell & Torres, 2002;Gaertner, Bertrand & Souplet, 2002;Grothues et al, 2002) and larger (Cartes & Sarda, 1992;Rapoport, 1994;Longhurst, 1998;Naranjo, Carballo & García-Gómez, 1998;Joyeux et al, 2001) in scale. The boundaries in the pelagic taxa coincide with clear transitional oceanic domains, according to the biogeochemical provinces defined by Longhurst et al (1995).…”

The range size distributions of 6643 species in ten different fish and invertebrate taxa dwelling in pelagic (latitudinal range sizes) and benthic (latitudinal and depth range sizes) habitats on both sides of the Atlantic Ocean (80 ∞ N -70 ∞ S) were studied. The objectives were to analyse: (1) the range size distribution patterns for the various taxa and whether they have right/left skewed or lognormal distributions; (2) the geographical species distributions, to ascertain whether the distribution ranges change with latitude (Rapoport's rule); and (3) the relationship between the depth ranges of benthic species and their maximum depth of occurrence and how depth range size distributions change with latitude. The pelagic taxa exhibited larger range sizes than did the benthic taxa, continental slope/rise species excepted. On the other hand, the boundaries between geographical provinces for both benthic taxa and pelagic taxa tended to occur in association with major oceanographic processes. The shape of the latitudinal range frequency distributions (LRFDs) of the pelagic organisms were distinctly left-skewed, and the LRFDs for most taxa were significantly different from lognormal. There was no common pattern for the distributions of the benthic organisms, which were lognormal in Cephalopoda, Stomatopoda, and Crustacea Decapoda and tended to be left-skewed and significantly different from lognormal in Pisces. The applicability of Rapoport's rule was not clearly inferable from the results, and the rule appears to be conditioned by the location of biogeographical boundaries and the endemism rate in the different biogeographical provinces. A clear increase in depth range size with maximum depth range was observable for benthic species, confirming previous studies. Species' depth range distributions displayed a discernible latitudinal pattern, right-skewed at high latitudes and left-skewed at low latitudes. The location of biogeographical boundaries, and endemism rate by biogeographical province were considered to be the factors most useful in explaining species' distribution patterns and their conformity or nonconformity to Rapoport's rule.

“…Although previous work has assessed the trophic structure of fish communities in the north‐west Atlantic Ocean, the transitional seas of Rhode Island Sound (RIS) and Block Island Sound (BIS) have not been adequately sampled by routine state and federal surveys (Garrison & Link, ; Jordaan et al , ; Smith & Link, ). Recent work, however, has shown that the fish community in Rhode Island Sound and Block Island Sound is highly complex, both in terms of spatial distribution and seasonal patterns (Mahon et al , ; Hale, ; Malek et al , ). Furthermore, Rhode Island and Block Island Sounds are an important migratory pathway for many fish species moving into and out of Narragansett Bay and Long Island Sound and support commercial and recreational fishing activities (Costa‐Pierce, ; Smythe et al , ; Hasbrouck et al , ).…”

A combination of dietary guild analysis and nitrogen (δ(15) N) and carbon (δ(13) C) stable-isotope analysis was used to assess the trophic structure of the fish community in Rhode Island and Block Island Sounds, an area off southern New England identified for offshore wind energy development. In the autumn of 2009, 2010 and 2011, stomach and tissue samples were taken from 20 fish and invertebrate species for analysis of diet composition and δ(15) N and δ(13) C signatures. The food chain in Rhode Island and Block Island Sounds comprises approximately four trophic levels within which the fish community is divided into distinct dietary guilds, including planktivores, benthivores, crustacivores and piscivores. Within these guilds, inter-species isotopic and dietary overlap is high, suggesting that resource partitioning or competitive interactions play a major role in structuring the fish community. Carbon isotopes indicate that most fishes are supported by pelagic phytoplankton, although there is evidence that benthic production also plays a role, particularly for obligate benthivores such as skates Leucoraja spp. This type of analysis is useful for developing an ecosystem-based approach to management, as it identifies species that act as direct links to basal resources as well as species groups that share trophic roles.

“…Other studies, such as Wagner & Austin (1999) in Chesapeake Bay and Mahon et al (1999) in the physically more stable marine environment, interpreted ordination results similar to the present ones as indications of a physically driven system, characterizing assemblages as ' indeterminate, potentially adaptable entities ' (Mahon et al, 1999). Other studies of large fishes, including studies from estuarine habitats (Hamerlynck et al, 1993;Marshal & Elliot, 1998;Wagner & Austin, 1999) and freshwater streams (Pires et al, 1999), also concluded that the distribution of fishes in the respective systems was driven by fluctuations in the environmental variables and not by biological interactions.…”

Associations between fish assemblages and environmental factors in nearshore habitats of a subtropical estuary

Salinity and inlet distance were the most consistent indicators of species groupings among the 40 most abundant fish species in the Indian River Lagoon (IRL), Florida. In contrast to findings of other studies conducted on small juveniles and forage fishes in the IRL, this study suggested that distributions of the more mobile organisms are influenced more by physical conditions than by biological interactions. Consequently, environmentally-corrected singlespecies models will be more effective in assessing changes in stock abundance and habitat preferences of mobile species in the IRL. Because of the fluctuations in physical conditions in the IRL and other estuaries, it may be inappropriate to use biologically based methods that rely solely on species interactions to assess fish stocks in those systems.
