Interactive Effects of Two Global Contaminants on Behavioral Variation in Brine Shrimp. [PDF]
Ecol EvolWildlife is often exposed to multiple pollutants with unknown joint effects. We tested how two aquatic pollutants at realistic levels alter activity in Artemia. Phenanthrene reduced average activity but not when mixed with 2,4‐dichlorophenol. Both pollutants and their mix reduced behavioral plasticity but not individuality, highlighting the importance ...

Experimental evidence of inbreeding avoidance in the hermaphroditic snail Physa acuta [PDF]
Evolutionary Ecology, 2006 Inbreeding depression should select for inbreeding avoidance behaviours. Here we test this hypothesis in two populations of the simultaneous hermaphroditic freshwater snail Physa acuta. We recorded the copulatory behaviour of 288 pairs of sib-mates, non-kin mates from the same population, or non-kin mates from two different populations.

Ecosphere, Volume 14, Issue 12, December 2023., 2023 Abstract Riffles are heterogeneous habitats that support diverse assemblages in natural streams. They are often constructed as part of stream restoration practice, including in degraded urban stream ecosystems, despite larger scale limits to ecological state.
