Intraspecific Aggression Towards Common Bottlenose Dolphin Calves, Northern Gulf Of Mexico, Errol Ronje, Sarah Piwetz, Heidi Whitehead, Keith D. Mullin
Intraspecific Aggression Towards Common Bottlenose Dolphin Calves, Northern Gulf Of Mexico, Errol Ronje, Sarah Piwetz, Heidi Whitehead, Keith D. Mullin
Gulf and Caribbean Research
Infanticide has been widely documented throughout the animal kingdom, and has generally been viewed as an evolved, or adaptive behavior for the perpetrators. Infanticide motivated by increased sexual access to females with calves, or the elimination of potential genetic competition in the form of calf-directed aggression or infanticide, has been proposed for delphinids including killer whales, Indo-Pacific humpback dolphins, Guiana dolphins, and bottlenose dolphins. However, reports of intraspecific aggression towards bottlenose dolphin calves are relatively infrequent, and accounts of confirmed infanticide are rarer still. Reporting instances of intraspecific calf-directed aggression aids researchers to better understand the socio-behavioral context of these …

Passive acoustic technology has become a useful and cost-effective method to collect data with very high temporal resolution that can be used to detect the presence, distribution, and remotely monitor soniferous marine biodiversity. In order to maximize the potential of bioacoustic and soundscape research in the oceans, understanding the association between the different realms of sound sources, species-specific calls and behavioral context of sound production are fundamental. A previously unknown vocalization was associated with a behavioral display of lionfish (Pterois spp.) by recordings with synchronous audio and video at deep coral reefs in both Puerto Rico and the Florida …
Description Of A New Sound Produced By Nassau Grouper At Spawning Aggregation Sites, Timothy J. Rowell, Michelle T. Schärer, Richard S. Appeldoorn
Description Of A New Sound Produced By Nassau Grouper At Spawning Aggregation Sites, Timothy J. Rowell, Michelle T. Schärer, Richard S. Appeldoorn
Gulf and Caribbean Research
This study identified a new sound produced by Nassau Grouper in association with, although potentially not exclusive to, an agonistic interaction at a spawning aggregation. We have also provided a behavioral and acoustic description for identification of this sound in future studies. The discovery of a third type of sound produced by Nassau Grouper further highlights the importance of acoustic communication coupled with visual displays in fishes. Furthermore, identification of a new sound increases the ability to document the presence of this endangered species at spawning sites. Future efforts may reveal that the sound is produced within additional behavioral contexts …
Luminescent Syllid (Odontosyllis Sp.) Courtship Display Densities Vary Across Marine Habitats Around South Water Caye, Belize, Mitchel Mccloskey, Joshua Scheil, Gregory J. Sandland, Gretchen A. Gerrish
Luminescent Syllid (Odontosyllis Sp.) Courtship Display Densities Vary Across Marine Habitats Around South Water Caye, Belize, Mitchel Mccloskey, Joshua Scheil, Gregory J. Sandland, Gretchen A. Gerrish

Bright—green luminescent clouds frequently occur at the surface of shallow waters of the Caribbean Sea. These clouds are produced by syllid polychaetes during courtship. Although temporal variation in the occurrence of these courtship displays has been documented throughout the diurnal and lunar cycle, other factors such as habitat type have not been well studied. In this study, we investigated how syllid courtship—display densities varied across 3 substrate types (grassbed, rubble and coral) over a 3 day period. In line with previous studies, we found that syllid courtship displays occurred over seagrass and rubble substrates; however, we also found that display …
