“…Although the rearing conditions may inXuence the performance of subsequent stages such as cyprids or postlarvae (Pechenik et al 1993;Qiu and Qian 1999;Pechenik 2006;McDonald et al 2009), earlier studies have mainly examined the settlement success of cyprids without a stress history (e.g., Dineen and Hines 1992;Thiyagarajan et al 2003a;Dahlstrom et al 2004;McDonald et al 2009). In this study, we focus on three understudied aspects of stress ecology: the interaction of stressors, their impact on early life stages, and the inXuence of stress history on subsequent life stages.…”

Being young in a changing world: how temperature and salinity changes interactively modify the performance of larval stages of the barnacle Amphibalanus improvisus

The fate of key species, such as the barnacle Amphibalanus improvisus, in the course of global change is of particular interest since any change in their abundance and/or performance may entail community-wide eVects. In the Xuctuating Western Baltic, species typically experience a broad range of environmental conditions, which may preselect them to better cope with climate change. In this study, we examined the sensitivity of two crucial ontogenetic phases (naupliar, cypris) of the barnacle toward a range of temperature (12, 20, and 28°C) and salinity (5, 15, and 30 psu) combinations. Under all salinity treatments, nauplii developed faster at intermediate and high temperatures. Cyprid metamorphosis success, in contrast, was interactively impacted by temperature and salinity. Survival of nauplii decreased with increasing salinity under all temperature treatments. Highest settlement rates occurred at the intermediate temperature and salinity combination, i.e., 20°C and 15 psu. Settlement success of "naive" cyprids, i.e., when nauplii were raised in the absence of stress (20°C/15 psu), was less impacted by stressful temperature/ salinity combinations than that of cyprids with a stress history. Here, settlement success was highest at 30 psu particularly at low and high temperatures. Surprisingly, larval survival was not highest under the conditions typical for the Kiel Fjord at the season of peak settlement (20°C/15 psu). The proportion of nauplii that ultimately transformed to attached juveniles was, however, highest under these "home" conditions. Overall, only particularly stressful combinations of temperature and salinity substantially reduced larval performance and development. Given more time for adaptation, the relatively smooth climate shifts predicted will probably not dramatically aVect this species.

“…After heating, the panels (60 × 60 mm) were placed in running seawater for 1 wk prior to use. Dineen & Hines (1992) have shown that substrata coated with extract from conspecific adults stimulate settlement in cyprids of Balanus improvisus. Therefore, extract from conspecific adults was included as a treatment factor to investigate the relative effects of microtexture and extract on recruitment separately and in combination.…”

“…Induced settlement by conspecific chemical cues has been shown for several barnacle species in laboratory experiments (e.g. Knight-Jones 1953, Crisp & Meadows 1962, Rittschof et al 1984, Dineen & Hines 1992 and in the field (e.g. Raimondi 1988a, Jarrett 1997, Wright & Boxshall 1999.…”

“…However, cues or processes that contribute to aggregated settlement in B. improvisus have not been investigated in field experiments. Dineen & Hines (1992) showed that cyprids of B. improvisus are stimulated to settle in the presence of extracts from conspecific and congeneric adults in a laboratory study. In their study, settlement was higher in containers with conspecific than with congeneric cues and was lowest in untreated containers.…”

“…The effects of age, in particular, have been reported for various species (e.g. B. amphitrite, B. improvisus, B. subalbidus, B. eburneus), with cyprid selectivity decreasing with increasing age and cyprids losing the ability to metamorphose after a certain age (Dineen and Hines 1992, Thiyagarajan et al 2002, Marechal et al 2004.…”

Modulation of gregarious settlement of the stalked barnacle, <em>Pollicipes pollicipes</em>: a laboratory study

Summary:Although recruitment patterns of Pollicipes pollicipes (Crustacea: Scalpelliformes) in the wild have been investigated, no studies have yet focused on the factors that affect settlement. In the present paper, settlement of P. pollicipes on conspecifics (gregarious settlement) was investigated in the laboratory as a function of environmental conditions (hydrodynamics, temperature, light and salinity), larval age and batch. This study aimed to understand how these factors modulate settlement in the laboratory and elucidate how they might impact recruitment patterns in nature. Maximum attachment on adults was 30-35%, with a one-week metamorphosis rate of 70-80%. Batch differences affected both attachment and metamorphosis. Attachment rate was higher at natural salinity (30-40 psu), with lower salinity (20 psu) decreasing metamorphosis rate. Cyprid attachment was stimulated by light conditions and circulating water. This might relate to a preference for positioning high in the water column in nature, but also to increased cyprid-surface contact in conditions of circulating water. Older cyprids (3 or 6 days) showed higher attachment than un-aged larvae, though fewer 6-day-old larvae metamorphosed. Temperature did not affect attachment rate, but the metamorphosis rate decreased at 14°C (compared with 17 or 20°C), implying that differences in temperature during the breeding season can affect how quickly cyprids metamorphose to the juvenile. Cyprids survived for prolonged periods (≥20 days; 40% survival), likely due to efficient energy saving by intercalating long periods of inactivity with fast bursts of activity upon stimulation.Keywords: stalked barnacles; larva; settlement; attachment; metamorphosis; cyprids; aquaculture. Modulación del asentamiento gregario del percebe, Pollicipes pollicipes: un estudio de laboratorioResumen: Aunque se han investigado los patrones de reclutamiento de Pollicipes pollicipes (Crustacea: Scalpelliformes) en la naturaleza, actualmente no existen estudios sobre los factores que afectan al asentamiento larval. En el presente trabajo, el asentamiento de larvas de P. pollicipes sobre adultos conspecíficos (asentamiento gregario) fue investigado en el laboratorio en función de las variables ambientales (hidrodinamismo, temperatura, luz y salinidad), la edad y los distintos lotes de larvas. Este estudio tuvo como objetivo comprender cómo estos factores afectaban al asentamiento en el laboratorio y elucidar el modo en que podrían afectar a los patrones de reclutamiento en el medio natural. La fijación máxima en adultos fue de 30-35%, con una tasa de metamorfosis de 70 a 80% en una semana. Las tasas de fijación y de metamorfosis variaron dependiendo de los distintos lotes de larvas. La tasa de fijación fue superior cuando la salinidad era la natural (30-40 psu), mientras que la tasa de metamorfosis disminuía cuando la salinidad era inferior (20 psu). La fijación de la larva cipris se estimulaba en condiciones de luz y agua circulante, lo que puede estar relacionado con la preferencia po...
