Relationship between species richness and morphodynamics in sandy beaches: what are the underlying factors?

Abstract: One of the most documented generalisations in sandy beach ecology is the trend for species richness of macroinvertebrates to decrease along a morphodynamic gradient from the dissipative to the reflective condition. This widely documented pattern remains unexplained, because the responsible ecological factors and underlying biological processes are still unknown. It has been proposed that swash condition, which changes significantly along the morphodynamic gradient, is the key limiting factor underlying this bi… Show more

“…This finding is in T sediment temperature, S salinity, Eh redox-potential, Chl-a chlorophyll a concentration, PHP phaeopigments concentration, CPE chloroplastic pigment equivalent, POC particulate organic carbon concentration, MD median grain size, r 1 inclusive graphic standard deviation, s k skewness coefficient, Prt proteins, Cho carbohydrates, TBN total bacteria number, q w harmonic rank coefficient accordance with the multicausal environmental severity hypothesis, which admits that species with different characteristics are controlled by different limiting factors (Brazeiro 2001). Taxon-specific responses to environmental variables may well be the reason for the different patterns revealed by the multivariate analyses.…”

“…coast orientation, shelf extent, bathymetry) (Short and Wright, 1983). This shore morphodynamic gradient seems to determine some characteristics of the benthic macrofauna, such as the well-known relationship existing between a trend in decreasing macroinvertebrate species richness along a gradient from dissipative to reflective shore conditions (Brazeiro, 2001). Thus, any artificial coastal defence structure, which includes Low Crested Structures (LCS) built to prevent coastline erosion, will impact softbottom benthic assemblages by altering both hydrodynamic and sedimentary characteristics of the surrounding habitats.…”

“…Hydrodynamic stress plays an important role in controlling spatial patterns of meiofauna density and community structure (Covazzi et al, 2001). Exposed marine beaches have been defined as physically stressful environments (McLachlan, 1983;Rodil & Lastra, 2004) and thus the best way to understand population variability in these ecosystems is by documenting responses to abiotic factors (Jaramillo & McLachlan, 1993;Brazeiro, 2001). …”
