A Detailed Characterization of the Whistle Repertoire of Fraser's Dolphins ( Lagenodelphis hosei ) From the Lesser AntillesNARA Subscribed
Fraser's dolphin ( Lagenodelphis hosei ) remains poorly studied due to its elusive behavior, rarity, and preference for deep offshore habitats. While dolphins use frequency‐modulated whistles for communication, detailed acoustic descriptions exist for only a few species. This study provides the first comprehensive characterization of Fraser's dolphin whistle acoustic structure and repertoire, based on recordings from eight gro...
High similarities in dorsal fin ratios of common bottlenose dolphins ( Tursiops truncatus ) in the Caribbean SeaNARA Subscribed
Dorsal fins, one of the most notable dolphin's physical features, play important kinematic and hydrodynamic roles and are related to physiological and environmental adaptation processes. Differences in dorsal fin shape have been recently associated with geographic variation, habitat specialization between ecotypes, and ontogenetic factors. We studied dorsal fin variation across several common bottlenose dolphin populations in...
Summary Trichoderma arundinaceum (Ta37) and Botrytis cinerea (B05.10) produce the sesquiterpenoids harzianum A (HA) and botrydial (BOT), respectively. TaΔTri5, an HA non‐producer mutant, produces high levels of the polyketide compounds aspinolides (Asp) B and C. We analyzed the role of HA and Asp in the B. cinerea ‐ T. arundinaceum interaction, including changes in BOT production as well as transcriptomic changes of BcBOT gene...
