Abstract The emergence of reproductive isolation is key in maintaining within- and between-species diversity one the initial steps speciation. In Iberian Peninsula, diverging populations Brachionus plicatilis rotifer create an ideal system to shed light on mechanisms that give rise isolation. Herein, we quantify degree behavioural two groups B. populations, namely, neighbouring by adaptation lo...

The toxicity of leachates from two municipal solid waste (MSW) landfills in Southern Italy was characterized using a toxicity identification evaluation procedure. The chemical and physical fractionation techniques were: pH adjustment, pH adjustment/filtration, pH adjustment/C(18) solid phase extraction, graduated pH and EDTA chelation. All the samples exhibited acute toxicity towards the bacter...

Little information is known about bioaccumulation of atrazine or the effects it has on consumers that ingest atrazine-contaminated prey. For that reason, freshwater microalgae Chlorella vulgaris cultures were exposed to different concentrations of atrazine for twenty-four hours and were then used as an exclusive food source for Brachionus calyciflorus for three days with the intent to evaluate ...
