Potential pathways, trophic transfer and bioindicators of microplastics in freshwater systems
Microplastic (MP) polymers, 0.1 µm - 5 mm in size, are ubiquitous within aquatic environments. Due to their small size there is a risk that they may infiltrate and transfer within aquatic food webs. Though a limited number ...
Temporal and spatial variation in group size of bottlenose dolphins (Tursiops truncatus) in the Shannon Estuary, Ireland
Bottlenose dolphin group size is known to be determined by food availability, social interactions and predator defence. This paper analyses data gathered over seven years from dolphin tour boats operating in the Shannon ...
