The vocal repertoire for the Florida manatee is quantitatively categorized from a sample of 1114 calls recorded 3 different habitats in Florida. First, vocalizations were into five call categories based on visual inspection spectrograms and following descriptions provided previous studies. Second, measurements 17 acoustic parameters, subjective classification scheme was validated using regression trees (CARTs) model-based cluster analysis paired with silhouette coefficients. CART revealed...
Antillean manatees produce vocalizations reported to be important for communication, but their vocal behavior throughout geographic range is poorly understood. A SoundTrap recorder (sample rates: 288/576 kHz) was deployed in Belize record of wild a seagrass channel and young rehabilitated released manatee shallow lagoon. Spectral analysis revealed broadband with frequencies up 150 kHz high proportion calls ultrasonic components. Ultrasonic frequency components appear prevalent repertoire may...
To survive cold winters, Florida manatees ( Trichechus manatus latirostris ) depend on artificial (i.e., power plants) and natural warm water sources such as springs passive thermal basins. Passive basins can provide critical habitat for short or extended periods of time. The Henry D. King Powerplant in Fort Pierce, discharged into Moore’s Creek until it went offline 1995. However, is unknown to what degree continue occupy this area how environmental factors influence their occurrence the...
Even among the understudied sirenians, African manatees (Trichechus senegalensis) are a poorly understood, elusive, and vulnerable species that is difficult to detect. We used passive acoustic monitoring in first effort acoustically detect provide characterization of their vocalizations. Within two 3-day periods at Lake Ossa, Cameroon, least 3367 individual manatee vocalizations were detected such most middle night dusk. Call characteristics as fundamental frequency, duration, harmonics,...
Vocal activity and signal characteristics of mammals are driven by several factors that result in both stability plasticity over multiple time scales. All three extant species manatee communicate with calls especially important for maintaining contact between cows calves. Determining if calf differ across will provide insights into the evolution species-specific acoustic communication traits. We investigated interspecific differences vocalizations calves Amazonian manatees (Trichechus...
Abstract Florida manatees ( Trichechus manatus ) produce five broadly defined call types (squeaks, squeals, high squeaks, chirps, squeak‐squeals) but their use in social and nonsocial settings is unclear. The goal of this study was to investigate whether categories structure manatee vocalizations varied with behavior. Multiple hydrophones were used record four different environments broad behavioral states. Vocalizations recorded from resting, cavorting, stressed, or feeding wild animals...
Captive animals typically develop anticipatory behaviors, actions of increased frequency done in anticipation an event such as feeding. Anticipatory behaviors can be indicator animal's welfare. However, for rehabilitating that are expected to reintroduced into the wild, these need extinguished ensure successful release. Scheduled activities feeding occur daily and vocalizations could potentially used identify behavior. Here, we tested hypothesis manatee calves modify their vocal production...
Abstract Geographic variation in the vocal behavior of manatees has been reported but is largely unexplored. Vocalizations wild West Indian ( Trichechus manatus ) were recorded with hydrophones Florida from latirostris ), and Belize Panama Antillean to determine if calls varied between subspecies geographic regions. Calls visually classified into five categories: squeaks, high squeals, squeak-squeals, chirps. From these categories, only three call types (squeaks, squeaks squeals) observed...
Many marine mammals exhibit diel trends in vocal production, which can provide information on habitat use and behavioral activity. In Belize, Antillean manatees (Trichechus manatus manatus) commonly inhabit small depressions the substrate or deep-water coves known as "resting holes". Determining if temporal their call production rate types between microhabitats insights into diurnal nocturnal activity patterns. Here, we investigate vocalization patterns of wild two adjacent resting holes off...
Abstract Wildlife tourism often focuses on marine mammals, and the growing frequency of human interactions raises concerns about sustainability these activities their impact aquatic species. Tourists have opportunity to view Florida manatee ( Trichechus manatus latirostris ) in various locations; however, level tourist activity some areas effects manatees are unknown. Preliminary studies essential assess whether warrant additional regulatory mitigation strategies based impact. Here, we...
<title>Abstract</title> Despite their vulnerable status, manatee conservation efforts are hindered because of limited scientific data due to the collection challenges. Bio-acoustic studies utilizing advanced computational analy- sis long-term recordings offer a promising approach for determining manatee’s presence and abundance. The following manuscript describes an artificial intelligence pipeline that effectively implements automatic identification counting. first step is fine-tuning pre- trained...
Harbor Branch Oceanographic Institute at Florida Atlantic University together with, NOAA's National Ocean Service/Center for Coastal Environmental Health & Biomolecular Research initiated a research program designed to assess environmental and anthropogenic stressors that may affect the health long-term viability of bottlenose dolphin populations inhabiting coastal regions South Carolina This collaborative is known as Risk Assessment Project. The project involves capture, sampling,...
