The spatial distribution of the subtidal benthic macrofauna and its relationship with environmental factors using geostatistical tools: a case study in Trapandé Bay, southern Brazil

Abstract: ABSTRACT. Modeling the distribution patterns of the estuarine macrobenthic community has revealed itself as a difficult task due to spatio-temporal heterogeneity. This study uses ordinary kriging and Poisson modeling to generate distribution maps of the subtidal benthic macrofauna in the Trapandé Bay (southeastern Brazil). Samples were taken in duplicate from 36 locations distributed along nine transects perpendicular to the main estuarine axis in October 2006 and March 2007. One-hundred and seventy taxa belon… Show more

“…The complexity driving ecological interactions can vary from one area to another within a habitat and can be difficult to model because habitat complexity contributes to ecosystem heterogeneity (de Souza et al, 2013 ). Spatial–temporal interactions of biological, hydrographic, and oceanographic characteristics with seafloor and shoreline topography can be significant ecosystem influences affecting benthic community characteristics, long-term maintenance of benthic energy hotspots, and thus marine animal distributions (Blanchard et al, 2013 ; Buhl-Mortensen et al, 2012 ; Grebmeier et al, 2015 ).…”

“…Faunal responses to organic matter concentrations are essentially a response to changes in nutrient pathways, feeding modes and physiological tolerance mechanisms to the decreasing oxygen availability associated with this type of disturbance ( Souza et al, 2013 ; Bon et al, 2021 ). Consequently, organically enriched environments tend to be dominated by more generalist and opportunistic taxa or r-strategist guilds, which are physiologically more resistant to oxygen deprivation ( Pearson & Rosenberg, 1978 ; Cardell, Sardà & Romero, 1999 ; Brauko et al, 2016 ).…”

“…The low OC in HCA compared to LCA can be attributed to its utilization by the deposit feeders. Souza et al (2013), emphasized that Magelonids are mainly non-selective surface deposit feeders, but some species exhibit alternate feeding mode (suspension feeding) (Fauchald and Jumars 1979), and such alteration in feeding strategies may support Magelonids to inhabit both muddy and sandy sediments (Rouse and Pleijel 2001).…”
