“…Concentrations that affect locomotory behavior are often similar to those causing growth impairment in the longer-term (Little and Finger, 1990;Melvin and Wilson, 2013). Detrimental effects of chemicals on locomotory behavior have also been reported for various invertebrate species (Salanki, 2000;Tu et al, 2010;Hellou, 2011;Pekar, 2012;Oliveira et al, 2013;Pereira et al, 2013;Fong and Ford, 2014) and in some studies directly shown to coincide with reduction in food intake as well (Das and Khangarot, 2011;Agatz et al, 2012;Nyman et al, 2013). This suggests that the role in growth impairment of both KEs, impairment of locomotion and reduction in food intake, may be conserved in a broad spectra of taxa.…”

Adverse outcome pathways (AOPs) organize knowledge on the progression of toxicity through levels of biological organization. By determining the linkages between toxicity events at different levels, AOPs lay the foundation for mechanism-based alternative testing approaches to hazard assessment. Here, we focus on growth impairment in fish to illustrate the initial stages in the process of AOP development for chronic toxicity outcomes. Growth is an apical endpoint commonly assessed in chronic toxicity tests for which a replacement is desirable. Based on several criteria, we identified reduction in food intake to be a suitable key event for initiation of middle-out AOP development. To start exploring the upstream and downstream links of this key event, we developed three AOP case studies, for pyrethroids, selective serotonin reuptake inhibitors (SSRIs) and cadmium. Our analysis showed that the effect of pyrethroids and SSRIs on food intake is strongly linked to growth impairment, while cadmium causes a reduction in growth due to increased metabolic demands rather than changes in food intake. Locomotion impairment by pyrethroids is strongly linked to their effects on food intake and growth, while for SSRIs their direct influence on appetite may play a more important role. We further discuss which alternative tests could be used to inform on the predictive key events identified in the case studies. In conclusion, our work demonstrates how the AOP concept can be used in practice to assess critically the knowledge available for specific chronic toxicity cases and to identify existing knowledge gaps and potential alternative tests.

“…The most common approach when one is assessing behavioral responses related to movement is to focus on displacement patterns such as swimming activities (orientation, posture, frequency, duration, and speed of movements), spontaneous activity, burst swimming, ability to capture prey and escape from predators, etc. (Nakamura ; Little et al ; Saglio et al ; Bridges ; Zhou and Weis ; Fleeger et al ; Ren et al ; Oliveira et al ; Bridi et al ; Jutfelt et al, ). Therefore, in behavioral ecotoxicology, the response considered as avoidance is, in reality, a predictive endpoint about what would be expected to occur if, under real field conditions, organisms were mandatorily and continuously exposed to contamination (Farr et al ).…”

The idea that the hazard of contaminants is exclusively related to their toxic effects does not consider the fact that some organisms can avoid contamination, preventing toxicity. Although inferences about avoidance are made in most behavioral ecotoxicology studies, assessment of the real spatial displacement (organisms moving toward another habitat to escape contamination) is difficult due to the type of exposure (confined and mandatory) used in the bioassays: a forced exposure approach. A complementary approach using nonforced exposure systems to assess how contaminants affect the spatial distribution of organisms in a bicompartmented (toxic or nontoxic) environment has long been described. Recently, this nonforced approach has been developed to include a multi compartmented system in which different samples can be simultaneously tested. The aim of the present review was to describe the importance of the nonforced, multicompartmented exposure approach to simulate a gradient or patches of contamination, to describe the 2 main exposure systems, and to highlight the ecological relevance of including spatial avoidance and habitat preference in ecotoxicological studies. The multicompartmentalization of the system makes it possible to simulate more complex scenarios and therefore include new ecological concepts in bioassays. We also contrasted spatial avoidance in the nonforced exposure systems with the behavioral endpoints measured under other exposure systems. Finally, we showed that the nonforced, multicompartmented exposure approach makes it possible 1) to improve environmental risk assessments by adding the dispersion pattern of organisms in a multihabitat scenario, and 2) to integrate ecological concepts such as recolonization of recovering habitats, loss of habitat connectivity, habitat fragmentation, and contamination-driven metapopulation, which have received limited attention in ecotoxicological studies.

“…Despite its high economic value, the availability of genomic and transcriptomic data for this shrimp in public databases is limited. In addition to its ecological and commercial importance, these species have proved to be suitable indicator species in ecotoxicology [4], [5]. In this study, we performed de novo transcriptome assembly and annotation for P. serratus from adults individuals, and from a pool of larvae, by next-generation sequencing.…”

The shrimp Palaemon serratus is a coastal decapod crustacean with a high commercial value. It is harvested for human consumption. In this study, we used Illumina sequencing technology (HiSeq 2000) to sequence, assemble and annotate the transcriptome of P. serratus. RNA was isolated from muscle of adults individuals and, from a pool of larvae. A total number of 4 cDNA libraries were constructed, using the TruSeq RNA Sample Preparation Kit v2. The raw data in this study was deposited in NCBI SRA database with study accession number of SRP090769. The obtained data were subjected to de novo transcriptome assembly using Trinity software, and coding regions were predicted by TransDecoder. We used Blastp and Sma3s to annotate the identified proteins. The transcriptome data could provide some insight into the understanding of genes involved in the larval development and metamorphosis.SpecificationsOrganism/cell line/tissuePalaemon serratus/muscle adults individuals and pool of larvaeSexN/ASequencer or array typeIllumina HiSeq2000Data formatRaw or processedExperimental factorsDe novo transcriptome assembly of Palaemon serratus.Experimental featuresRNA was isolated from muscle of adults individuals and, from a pool of larvae.
