We determined the probability of mating as a function of population density in the estuarine copepod Acartia hudsonica by combining experimental measurements with a simple model. Pairs of unmated copepods were confined in containers of various volumes to simulate variable population density, and experiments were run for 8, 16, and 24 h. Mating frequencies indicated that males search for females...

Introduction Copepods present the largest and most diverse group of zooplankton their feeding behavior can affect top-down bottom-up processes. Thus, how efficient is executed determines abundance copepods’ prey predators and, with that, carbon transfer storage in ecosystems. The rise anthropogenic underwater noise from shipping, oil exploration exploitation, wind farm construction operation, m...

Abstract The impact of the occurrence non-indigenous species (NIS) Acartia tonsa , Oithona davisae and Pseudodiaptomus marinus range-expanding copepods bifilosa Calanipeda aquaedulcis on structure diversity zooplankton communities was analyzed using 18 years (1998–2015) time series from contrasting estuaries Bilbao Urdaibai (Basque coast, Bay Biscay). Changes in were assessed by multivariate an...
