However, another study from Beerends [28] based on 25-s commercials reported asymmetric interaction effects with a noticeable influence of the video quality level on the perceived audio quality (0.5 on a 5-point MOS scale) and a weaker influence of the audio quality level on the perceived video quality (only 0.15 on a MOS).
Overall, the level of invasion has a weak influence on pollination network structure and seems to be associated with only one metric, H 2 ′ which measures the level of selectiveness; thus, as invasion progresses, species in the network appear to become more selective in their choice of partners, interacting with less abundant species more than would be expected by chance.
