Each object has a default depth preference value which may be set in the ChIPS resource file or by calling the set_preference function.
To obtain representative daily parameters of depth preference we first tested for the presence or absence of any diurnal variation in dive depth (DDV) by comparing a sigmoidal vs an intercept-only linear model of dive depth as a function of time of day.
Many other rockfish species share this shallow depth preference (Table 8, Love et al. 2002; Berntson and Moran 2009) and are unlikely to be protected by the deepwater reserves.
Farmer, E. C., Kaplan, A., de Menocal, P. B. & Lynch-Stieglitz, J. Corroborating ecological depth preferences of planktonic foraminifera in the tropical Atlantic with the stable oxygen isotope ratios of core top specimens.
IBMs using realistic larval ecology are key: marine larvae do not generally behave passively31,32,33,34, and their behaviours, particularly depth preferences and vertical swimming abilities, have large effects on dispersal35,36,37.
Univariate analysis showed species richness increasing from the high intertidal zone to 1 m subtidally, with distinct depth preferences among the 23 species.
Depth preferences of the 44 fish reporting time series data differed significantly between day and night (Kolmogorov-Smirnov test, P<0.05); fish spent more time in surface waters (<50 m) during the night than during the day.
Three wetland species with well-documented differences in flooding tolerance adaptations, depth preferences and responses to water depth were used.
The three species in this study differed considerably in their morphology, but relative responses of specific morphological parameters relevant for each taxon to similar depth ranges were able to distinguish their depth preferences and tolerances.
This study compared the growth responses to water depth of three species (Phormium tenax, Carex secta and Typha orientalis) differing in depth preferences in wetlands, using non-linear and quantile regression analyses to establish how flooding tolerance can explain field zonation.
SPARC has also been proposed to modulate synaptic functions and to be involved in higher cortical functions in adult mammalian brains [ 39], making this a candidate for depth-preference behaviour [ 1].
