The diet of Prionotus nudigula in coastal waters off Uruguay and northern Argentina (36°–41° S) and their variation in relation to body size, region and season were determined by analysis of stomach contents. Additionally, the trophic level of this species was estimated to establish its ecological role in this marine region. A total of 352 individuals were analysed, of which 308 (87.05%), ranging from 78 to 285 mm in total len...

Aims Pseudomonas chlororaphis PCL1606 (PcPCL1606), displays strong antagonistic and biological control abilities against several soil-borne fungal pathogens mainly due to the production of the antifungal molecule 2-hexyl, 5-propyl resorcinol (HPR). HPR governs other beneficial phenotypes, suggesting its additional regulatory activity. Published transcriptomic data identifying HPR-regulated genes involved in the interaction of...

Five adult paralichthyid specimens with various kinds of abnormalities are reported from the south‐west Atlantic Ocean. These abnormal flatfish specimens represent the first records of wholly ambicoloured Paralichthys orbignyanus specimens having a deep notch between the eye and dorsal fin and a partially albinistic specimen having skeletal deformities and only the second record of an almost totally ambicoloured specimen. We a...

The goals of this study were to describe the diet and estimate the trophic level and food selection of Jenyns's sprat Ramnogaster arcuata , one of the common fishes in the Bahía Blanca estuary in Argentina. The copepods Acartia tonsa [53·7% index of relative importance ( I RI )] and Eurytemora americana (13·4% I RI ), the mysid Arthromysis magellanica (13·9% I RI ) and the small shrimp Peisos petrunkevitchi (8·2% I RI ) were t...
