Population and species persistence in a rapidly warming world will be determined by an organism’s ability to acclimate to warmer conditions, especially across generations. There is potential for transgenerational acclimation but the importance of ontogenetic timing in the transmission of environmentally induced parental effects remains mostly unkno...
The environment experienced by one generation has the potential to affect the subsequent one through non‐genetic inheritance of parental effects. Since both mothers and fathers can influence their offspring, questions arise regarding how the maternal, paternal and offspring experiences integrate into the resulting phenotype. We aimed to disentangle...
The majority of the transcribed genome does not have coding potential but these non‐coding transcripts play crucial roles in transcriptional and post‐transcriptional regulation of protein‐coding genes. Regulation of gene expression is important in shaping an organism's response to environmental changes, ultimately impacting their survival and persi...
Temperature is a primary factor affecting the physiology of ectothermic animals and global warming of water bodies may therefore impact aquatic life. Understanding the effects of near-future predicted temperature changes on the behaviour and underlying molecular mechanisms of aquatic animals is of particular importance, since behaviour mediates sur...

There is potential for transgenerational acclimation, but the importance of ontogenetic timing in the transmission of environmentally induced parental effects remains mostly unkn...
Temperature is a primary factor affecting the survival, development, and physiology of aquatic ectothermic animals and global warming of water bodies may therefore impact several biological levels of aquatic life. Understanding the effects of near-future predicted temperature changes on the behaviour and the underlying molecular mechanisms of aquat...
The parental environment can alter offspring phenotypes via the transfer of non‐genetic information. Parental effects may be viewed as an extension of (within‐generation) phenotypic plasticity. Smaller size, poorer physical condition, and skewed sex ratios are common responses of organisms to global warming, yet whether parental effects alleviate,...

The Arabian pupfish, Aphanius dispar , is a euryhaline fish inhabiting both inland nearly-freshwater desert ponds and highly saline Red Sea coastal lagoons of the Arabian Peninsula. Desert ponds and coastal lagoons, located respectively upstream and at the mouths of dry riverbeds (“wadies”), have been found to potentially become connected during pe...
The Arabian pupfish, Aphanius dispar, is a euryhaline fish inhabiting both inland nearly-freshwater desert ponds and highly saline Red Sea coastal lagoons of the Arabian Peninsula. Red Sea populations have been found to receive migrants from desert ponds that are flushed out to sea during flash floods, requiring rapid acclimation to a greater than...
The unstable nature of freshwater ponds in arid landscapes represent a sizable challenge for strictly aquatic organisms, such as fishes. Yet the Arabian Desert, bordering the coastline of the Red Sea, plays host to a species very well adapted to such extreme environments: the Arabian pupfish, Aphanius dispar. In this study, we estimated patterns of...
Global warming can disrupt reproduction or lead to fewer and poorer quality offspring, owing to the thermally sensitive nature of reproductive physiology. However, phenotypic plasticity may enable some animals to adjust the thermal sensitivity of reproduction to maintain performance in warmer conditions. Whether elevated temperature affects reprodu...
In this study the annual reproductive biology of a Procambarus clarkii (Girard, 1852) population living in an atypical habitat with cold spring waters is investigated by monitoring Gonado-Somatic and Hepato-Somatic Indexes (GSI and HSI) and by performing cytology on ovaries. Despite its known preference for habitats with water temperature from 21 t...
RNA interference has frequently been applied to modulate gene function in organisms. With the aim of creating new autocidal methods based on neuro-endocrine disruptors for invasive populations of Procambarus clarkii, we silenced the Crustacean Hyperglycemic Hormone (CHH) by injecting the corresponding dsRNA. CHH is a pleiotropic hormone that primar...

Hello,
I have miRNA data from a non-model species (fish) and I am trying to identify the putative gene targets of the differentially expressed miRNAs due to my treatment.
From the literature, a common practice seems to get the overlap between the results of TargetScan, Miranda and RNAhybrid + svm_light. After running the three softwares, I am now trying to understand how to use svm_light. I am not familiar with SVM and I can't seem to find any tutorial or clear explanation on how to use svm_light on RNAhybrid results.
Can anyone either point me in the right direction or explain me how to use svm_light?
Thanks!
Hello,
I work with a non model organism (fish) and I am approaching miRNA analyses for the first time. Most of the papers I have read remove tags that align to exons, introns and repeat sequences of the reference genome, and use the unaligned tags to identify conserved and novel miRNAs. Could anyone please explain me why they remove these tags? I have read that a good proportion of miRNAs originates from intronic and exonic regions of other genes, so why should we get rid of them?
Hello, I need to extract DNA and RNA from fish mature spermatozoa and unfertilised oocytes. I am also looking for a protocol to isolate mature spermatozoa from fish semen/testis and any advice on how to proceed with oocyte DNA/RNA extraction.
