We analyse the impact of ship traffic in the vicinity of navigation channels in a wide shallow waterbody. The crucial hydrodynamic driver in this situation is the depression (Bernoulli) wake that may be transferred into a long-living solitary wave of depression over the shoals. The analysis considers navigation channels in the Venice Lagoon using a new large dataset of approximately 600 measured wake events associated to specific ships whose data are provided by the AIS system. Since the development of the modern industrial port and the opening of the Malamocco–Marghera channel in the late 1960s, growing pressure on the lagoon …

Glyphosate based herbicides (GBH) like Roundup® are used extensively in agriculture as well as in urban and rural settings as a broad spectrum herbicide. Its mechanism of action was thought to be specific only to plants and thus considered safe and non-toxic. However, mounting evidence suggests that GBHs may not be as safe as once thought as initial studies in frogs suggest that GBHs may be teratogenic. Here we utilize the zebrafish vertebrate model system to study early effects of glyphosate exposure using technical grade glyphosate and the Roundup® Classic formulation. We find morphological abnormalities including cephalic and …

Zebrafish provide a powerful model of the impacts of embryonic toxicant exposure on neural development that may result in long-term behavioral dysfunction. In this study, zebrafish embryos were treated with 1.5mM strychnine for short embryonic time windows to induce transient changes in inhibitory neural signaling, and were subsequently raised in untreated water until adulthood. PCR analysis showed indications that strychnine exposure altered expression of some genes related to glycinergic, GABAergic and glutamatergic neuronal synapses during embryonic development. In adulthood, treated fish showed significant changes in swimming speed and tank diving behavior compared to controls. Taken together, these data show that …

Part of an ongoing population study of the North American Horseshoe Crab, Limulus polyphemus, in Long Island Sound was completed during the 2003 – 2005 spawning seasons at Milford Point, in Milford, CT. Horseshoe crabs range more widely throughout Long Island Sound than expected and exhibit weak site fidelity. Animals originally tagged in Milford were found as far west as Stamford and as far east as Clinton, CT. during the 3 year study. Out of 522 female horseshoe crabs tagged in 2004 only 4 came back to spawn again at Milford Pt. in 2005. The sex ratios of tagged and …
