Disaggregation behavior in the terrestrial isopod Porcellionides pruinosus as a new ecotoxicological endpoint for assessing infochemical disrupting activity

open access: yesEcological Indicators
Among rapid ecotoxicological bioassays for screening soil quality, avoidance behavior tests on gregarious edaphic species such as Porcellionides pruinosus are widely used.

Stability analysis for the phytoplankton-zooplankton model with depletion of dissolved oxygen and strong Allee effects

open access: yesResults in Engineering
The photosynthetic activity of phytoplankton in the seas is responsible for an estimated 50–80 % of the world's oxygen generation. Both phytoplankton and zooplankton require some of this synthesized oxygen for cellular respiration.

Threshold dynamics scenario of a plants-pollinators cooperative system with impulsive effect on a periodically evolving domain

open access: yesEuropean Journal of Applied Mathematics
Flowering plants depend on some animals for pollination and contribute to nourish the animals in natural environments. We call these animals pollinators and build a plants-pollinators cooperative model with impulsive effect on a periodically evolving ...
