In sessile marine invertebrates, larval settlement is fundamental to population maintenance and persistence. Cues contributing to the settlement choices and metamorphosis of larvae have important implications for the success of individuals and populations, but cues mediating larval settlement for many marine invertebrates are largely unknown. This study assessed larval settlement in two common ...

Coral populations, and the productive reef ecosystems they support, rely on successful recruitment of reef-building species, beginning with settlement of dispersing larvae into habitat favourable to survival. Many substrate cues have been identified as contributors to coral larval habitat selection; however, the potential for ambient acoustic cues to influence coral settlement responses is unkn...

Based on the method of BP neural network,a foundation settlement of BP neural network prediction model was established for a railway subgrade in HeFei area China. In the model, the previous field monitoring data was used as the training sample and the later settlement was predicted. The model was used for four test sections of the railway subgrade. The results showed that for the four test sect...

We present a spatial interaction entropy maximizing and structural dynamics model of settlements from the Middle Bronze Age (MBA) and Iron Ages (IA) in the Khabur Triangle (KT) region within Syria. The model addresses factors that make locations attractive for trade and settlement, affecting settlement growth and change. We explore why some sites become relatively major settlements, while other...

Several recent ®eld studies have found disproportionately high barnacle settlement rates (expressed on a per-area basis) in situations where the amount of suitable substrate is reduced, either due to occupation by other individuals or to physical processes. We call this phenomenon the intensi®cation e€ect; it is not included in many models of benthic populations, which assume that the per-area ...

A total of ten seaweeds and four seagrasses were used in the present investigation to study the effect of crude methanol extracts on anti-biofilm activity using a microtiter-plate and anti-larval settlement assay using cyprids of barnacle Balanus amphitrite. Of these fourteen species tested, seagrass Halophila ovalis showed noticeable anti-biofilm activity against Listeria monocytogenes, Vibrio...

Deformation monitoring is a significant work for engineering safety, which is performed throughout the entire process of engineering design, construction and operation. Based on the theoretic analysis of wavelet and neural network, we applied the improved BP neural network model, auxiliary wavelet neural network model and embedded wavelet neural network model to the settlement prediction in one...

Ecology Letters (2012) 15: 338-346 ABSTRACT: Successful recruitment in shallow reef ecosystems often involves specific cues that connect planktonic invertebrate larvae with particular crustose coralline algae (CCA) during settlement. While ocean acidification (OA) can reduce larval settlement and the abundance of CCA, the impact of OA on the interactions between planktonic larvae and their pref...

western parts of the chaharmahal and bakhtiyari province (ardal county) due to containing high mountains, deep valleys and small intermountain plains as well as the placement in the path of the nomads have long been of interest to humans. the nomadic communities of the mountainous regions of chaharmahal va bakhtiyari culturally interacted with the lowland areas of fars and khuzestan's plai...

The effect of substratum heterogeneity on the distribution and abundance of sessile epibenthos was studied between May 1980 and September 1981, in a mid-intertidal shore subject to severe annual ice scouring during winter In summer, low abundances of organisms were associated with smooth regular surfaces whereas high abundances were associated with higher heterogeneity in the form of cracks and...
