The effects of culture conditions and chloramphenicol treatment on the induction of the marine bacterium Pseudoalteromonas spongiae to larval settlement of Hydroides elegans were investigated. The results showed that P. spongiae cells grown in the medium containing both yeast extract and peptone (YP-grown P. spongiae) was highly inductive to larval settlement, whereas P. spongiae cells grown in...

Serial roentgenograms of 40 patients who had 70 cervical intervertebral spaces grafted with ethylene oxide sterilized cadaver bone and 28 patients who received 44 iliac crest auto grafts for anterior cervical spine fusion, were studied. The radiological evaluation was made on the basis of settlement of intervertebral spaces, fusion rate, delayed union, non-union, graft collapse and extrusion of...

Initial and Subsequent Location Choices of Immigrants to the Netherlands The initial settlement behaviour and the subsequent mobility of immigrants who arrived in the Netherlands in 1999 are examined using rich administrative individual data. The study considers the settlement patterns of immigrants from various countries of origin who entered the country as labour, family or asylum migrants. T...

Settlement inhibition of barnacle (Amphibalanus amphitrite) cypris larvae resulting from exposure to ultrasound was measured at three frequencies (23, 63, and 102 kHz), applied at three acoustic pressure levels (9, 15, and 22 kPa) for exposure times of 30, 150, and 300 s. The lowest settlement was observed for 23 kHz, which also induced the highest cyprid mortality. Cyprid settlement following ...

ABSTRACT: This paper presents the settlement analysis of a beam resting on geosynthetic reinforced granular fill-soft soil system. Each subsystem of the reinforced fill-soil system is idealized by elastic membrane, Pasternak shear layer, Winkler springs and dashpots, as applicable. The suggested model incorporates various aspects of the behavior of the geosynthetic-reinforced granular fill-soft...

Otolith-based reconstructions of daily larval growth increments were used to examine the effect of variation in larval growth on size and age at settlement and post-settlement growth, survival and habitat preferences of juvenile bicolor damselfish (Stegastes partitus Poey). During August 1992 and 1994, newly settled S. partitus were collected from Montastraea coral heads and Porites rubble pile...

An increased understanding of the role of early life history stages in determining the distributions of benthic invertebrates require studies covering a wide range of habitats, and preferably multiple scales. For one of the more prominent invertebrate groups, intertidal barnacles, much of our existing knowledge is drawn from studies of rocky shores, with few studies from other habitats. Here, w...

Understanding how the density and spatial arrangement of invaders is critical to developing management strategies of pest species. The Pacific oyster, Crassostrea gigas, has been translocated around the world for aquaculture and in many instances has established wild populations. Relative to other species of bivalve, it displays rapid suspension feeding, which may cause mortality of pelagic inv...

Recruitment patterns of marine invertebrates are strongly influenced by the habitat preference of larvae as larvae can choose to settle (or not) in response to positive or negative cues. High abundances of recruits of the native infaunal bivalve Anadara trapezia occur in the invasive alga Caulerpa taxifolia compared to native habitats. Using controlled laboratory experiments, A. trapezia larval...

The Pomacentridae (damselfish) and Apogonidae (cardinalfish) are among the most common fish families on coral reefs and in the aquarium trade. Members of both families undergo a pelagic larvae phase prior to settlement on the reef, where adults play key roles in benthic habitat structuring and trophic interactions. Fish-associated microbial communities (microbiomes) significantly influence fish...
