Intraguild predation in sympatric seals and the effect on a declining population
This study examined the prevalence, spatial extent, and temporal trends of grey seal intraguild predation (IGP). We demonstrated the utility of integrating disparate datasets to address conservation challenges and highlighted how IGP, while seemingly rare, can hold sympatric species in a predator‐pit and in small populations may contribute to declines.

Bacteria are known to influence domoic acid (DA) production by Pseudo-nitzschia spp., but the link between DA production and physiology of diatoms requires more investigation. We compared a toxic P. multiseries to a non-toxic P.

Stability of Domoic Acid in Saline Dosing Solutions [PDF]
Abstract Studies designed to assess the effects of repeated low doses of domoic acid require an assessment of its stability in solution under the conditions used for in vivo studies. The stability of 1 mg/mL solutions of domoic acid in saline, with or without ascorbic acid, was determined for 15 weeks.
