Environmental conditions (depth, salinity, depth, sediment load, food input, hydrography) vary across the Eurasian Arctic and are probably responsible for part of this trend; but sampling effort also varies in a similar way.
It is a network physical system with a controllable, credible, and scalable function on the basis of environmental perception, depth fusion calculation, communication, and control ability.
The environmental variables depth, slope, type of substrate, Bathymetric Position Index (BPI) and Vector Ruggedness Measure (VRM) were the variables with higher influence on the distribution of communities.
The study was carried out at three sites, located on the coast of Cantabria (N. Spain), covering a variety of environmental conditions (depth ranges and anthropogenic pressures).
At large scales (100 s of meters), we hypothesised that canyon heterogeneity would drive organic matter patterns: topographic features (slope, aspect, curvature, rugosity, and benthic positioning index) and other environmental variables (depth, dissolved oxygen concentration, surface primary productivity, and sediment type).
The various manifestations of being a highly sensitive person -- inhibition of behavior, sensitivity to environmental stimuli, depth of information processing, and physiological reactivity -- are linked to neuroticism and intellect/imagination, not to introversion.
Redundancy analysis (RDA) assesses how biotic factors of the amphioxus population (mean size, density, and abundances of juveniles (<30 mm), adults (>30 mm), and all individuals) are explained by environmental variables (depth and sediment granulometry).
Jennings et al. [29], Zühlke et al. [93], and Callaway et al. [94] found that the epibenthic diversity was correlated with environmental variables (depth, sediment type, annual temperature range).
Amphioxus size (on individuals) and density (on stations) were also separately studied using multiple regressions against environmental variables (depth and particle size (silt, sand, gravel)) followed by a forward selection of significant explanatory variables (see [20]).
We found that the important environmental variables were depth and Ub, while no effect of slope was found.
