PG - 112054 LID - S0025-326X(21)00088-6 [pii] LID - 10.1016/j.marpolbul.2021.112054 [doi] AB - This work presents the structural and functional traits of benthic amphipods in the Saudi waters of the Arabian Gulf. Sixty-two species belonging to 37 genera and 17 families were recorded. Sensitive species such as Grandidierella bonnieroides, G. exilis, Gammaropsis atlantica and Caprellidea indet., were mostly dominant. The average values of richness, density and diversity (H' log(2)) were 11 +/- 1, 512 +/- 232 ind. m-2 and 3.1 +/- 0.1 respectively. The density decreased with increased in depth (nearshore (NS) - 784 +/- 445 and offshore (OS) - 222 +/- 28, p = 0.023), while evenness (NS - 0.93 and OS -0.94) and diversity (NS - 3.10 and OS - 3.18) were unaffected by depth. Interstitial space dwellers (56.76%) and surface deposit feeders (60.16%) were dominant in the nearshore sand substratum. However, domicolous (72.2%) with suspension and surface deposit feeders (71.7%) were more in offshore silt sediments. The combination of depth, pH and TPH (p = 0.249) influenced the distribution of amphipods. CI - Copyright (c) 2021 Elsevier Ltd. All rights reserved.
