TranscriptomicsAdaptive differences in gene expression associated with stress tolerance in the soil arthropod Orchesella cincta
Field-selected tolerance to heavy metals has been reported for Orchesella cincta (Arthropoda: Collembola) populations occurring at metal-contaminated mining sites. This tolerance is correlated with heritable increase of metal excretion efficiency; less pronounce cadmium induced growth reduction and,...

TranscriptomicsFolsomia candida exposed to soil containing different phenanthrene concentrations
Polycyclic aromatic hydrocarbons are common pollutants in soil, have negative effects on soil ecosystems, and are potentially carcinogenic. The Springtail (Collembola) Folsomia candida is often used as an indicator species for soil toxicity. Here we report a toxicogenomic study that translates the e...

TranscriptomicsGenetic variation in parthenogenetic collembolans is associated with differences in fitness and cadmium-induced transcriptome responses
Ecotoxicological tests may be biased by the use of laboratory strains that usually contain very limited genetic diversity. It is therefore essential to study how genetic variation influences stress tolerance relevant for toxicity outcomes. To that end we studied sensitivity to cadmium in two distinc...

TranscriptomicsCombined transcriptomics classifier analysis reveals a set of adverse effect genes for use as potential endpoint in effect based screening
Environmental risk assessment relies heavily on the use of bioassays to assess the environmental impact of chemicals. Gene expression is gaining acceptance as a valuable mechanistic endpoint in bioassays and effect-based screening. Data analysis and its results however, are often complex and not dir...

TranscriptomicsClassifier analysis of gene expression profiles reveals a discriminatory gene set for soil containing different metals
Environmental pollution is a worldwide problem, and metals are the largest group of contaminants in soil. Microarray toxicogenomic studies with ecologically relevant organisms such as springtails, supplement traditional ecotoxicological research, but are presently rather descriptive. Classifier anal...

TranscriptomicsTranscriptional plasticity of a soil arthropod across different ecological conditions
It has long been recognized that species occupy a specific ecological niche within their ecosystem. The ecological niche is defined as the number of conditions and resources that limit species distribution. Within their ecological niche, species do not exist in a single physiological state but in a ...

TranscriptomicsTranscriptional responses of Folsomia candida exposed to polar and apolar narcotizing compounds.
Narcosis or baseline toxicity is the inert toxicity of hydrophobic compounds, supposed to take place at the level of the cellular membranes. Based on the linear relationship between the toxicity (logEC50) and the hydrophobicity (logKow), class I and II narcotizing compounds are recognized, in whic...

TranscriptomicsEcotoxicogenomic assessment of diclofenac toxicity in soil
This study investigates transcriptional responses of the springtail Folsomia candida to two relevant concentrations of diclofenac A direct design was used where springtails were exposed to 3two concentrations of diclofenac (EC10 and EC50 on reproduction) and microarrays were directly contrased to th...

TranscriptomicsTranscriptome assembly and microarray construction for Enchytraeus crypticus, a model oligochaete to assess stress response mechanisms derived from soil conditions
The soil worm Enchytraeus crypticus (oligochaete) is an ecotoxicology model species although without genome or transcriptome sequence information. The present research aimed at studying, via high-throughput pyrosequencing, the transcriptome of Enchytraeus crypticus, sampled from multiple test condit...

TranscriptomicsMechanisms of phenanthrene toxicity in the soil invertebrate Enchytraeus crypticus
Polycyclic Aromatic Hydrocarbons (PAHs) continue to cause environmental challenges due to their release in the environment by a great variety of anthropogenic activities and their accumulation in soil ecosystems. Here we studied the toxicological effect of the model PAH phenanthrene (Phe) on the soi...
