White-tailed eagle more vulnerable than many. Besides vulnerability, habitat and prey behaviour, fish body size may be a driver in the piscivorian dietary preferences. Studies have indicated that fish less than are taken infrequently, since they have a lower yield, fish of up to are taken secondarily and fish between are preferred since they have the highest nutritional benefit. Fish taken can exceed but since they can start to considerably exceed the weight of the eagle itself, they may be prove too difficult to overpower. One large Atlantic halibut ("Hippoglossus hippoglossus") was found with the disembodied feet of a white-tailed eagle still
IsomiR isomiRs have been detected deregulated in D. melanogaster development and differential expressed during "Hippoglossus hippoglossus" L. early development, suggesting a biologically relevant function. IsomiR isomiR is a term coined by Morin et al. to refer to those sequences that have variations with respect to the reference miRNA sequence. miRBase is considered to be the gold-standard miRNA database—it stores miRNA sequences detected by thousand of experiments. In this database each miRNA is associated with a miRNA precursor and with one or two mature miRNA (-5p and -3p). Similarly, VIRmiRNA is the only available resource for miRNA in the field of virus.
