Using an environmental DNA approach, we confirmed the presence of C. asper in eight out of 13 sites deemed climatically suitable for the species, although it had never been observed there before. Then, we sampled brown trout (Salmo trutta) living in sympatry with C. asper and, through fish faeces analyses, confirmed that brown trout are predators of C. asper. Leer más.
This study proposes a novel experimental methodology, capitalising on thermography, to provide an alternative method to less invasively obtain reliable body temperatures of thermoregulating ectotherms, while allowing behaviour and heating mode to be considered when quantifying thermal exchange rates.

Selection on specific promoter regions indicated adaptive evolution in transcription factor binding sites with the potential to enhance transcriptional flexibility, resulting in increased cellular stress tolerance. Leer más.
