Abstract:
ABSTRACT Providing rapid and humane care for distressed or threatened marine mammals is crucial to the ultimate success of such actions. Recently, in the southeast United States, marine mammals were observed in the vicinity of several oil spills. Proper coordination of marine mammal rescue or recovery actions with the Unified Command (UC) is essential for response personnel safety and increased probability of saving the affected animals. In the event of animal mortalities, effective coordination between the marine mammal resource agencies and the UC helps ensure the preservation of causal evidence. National Oceanic and Atmospheric Administration'S (NOAA'S) Office of Response and Restoration (OR&R), generally through the NOAA Scientific Support Coordinator (SSC), is able to assist the Federal On-Scene Coordinator (FOSC) and UC in addressing the threat of spilled oil on potentially affected marine mammals. Response actions during recent spills included: documenting the animals’ type and location, notification of the marine mammal agencies and teams responsible for their recovery and care, and coordination between the spill response and the marine mammal response. The actions of responders during recent spills involving marine mammals are summarized and relevant issues discussed, including properly characterizing the threat to marine mammals from spilled oil. The recent oil spill responses involving marine mammals in the southeastern U.S. are applicable to future spills throughout the United States and potentially worldwide. These recent incidents underscore the need to fully understand and plan for high profile wildlife issues during oil spill responses.

Abstract:
Globally, the marine mammal population has been under threat due to various human activities. Data on stranding of these animals that are important for effective conservation planning and management, however, are not available in most of the developing countries. This paper presents observations on marine mammal strandings in northern Palk Bay, the southeastern coast of India over the last decade. In total, 21 stranding events consisting of 23 marine mammals were observed from 2009 to 2020. These stranded mammals include a Humpback Dolphin, a Blue Whale, two Finless Porpoises, and 19 Dugongs. The evident reason for the death of the dugongs and the porpoise being fishing activities, regulations on fishing practices, and intensive monitoring of the existing dugong population and their habitats are necessary. This study recommends for establishment of conservation reserve, and setting up district-level marine mammal rescue and release units in Nagapattinam, Tiruvarur, Thanjavur, Pudukkottai, and Ramanathapuram districts, comprising fishers and line departments. These units need to be sufficiently equipped in terms of equipment and infrastructure, and periodical technical training and workshops on marine mammal rescue and release procedures to quickly respond and handle marine mammal strandings in the area.

Abstract:
The ancestors of marine mammals once roamed the land and independently committed to an aquatic lifestyle. These macroevolutionary transitions have intrigued scientists for centuries. Here, we generated high-quality genome assemblies of 17 marine mammals (11 cetaceans and six pinnipeds), including eight assemblies at the chromosome level. Incorporating previously published data, we reconstructed the marine mammal phylogeny and population histories and identified numerous idiosyncratic and convergent genomic variations that possibly contributed to the transition from land to water in marine mammal lineages. Genes associated with the formation of blubber (NFIA), vascular development (SEMA3E), and heat production by brown adipose tissue (UCP1) had unique changes that may contribute to marine mammal thermoregulation. We also observed many lineage-specific changes in the marine mammals, including genes associated with deep diving and navigation. Our study advances understanding of the timing, pattern, and molecular changes associated with the evolution of mammalian lineages adapting to aquatic life.

Abstract:
Eastern Indonesia is known as the center of marine biodiversity of the world as well as habitat and marine mammal migration path. Not all marine mammal events in eastern Indonesia are well documented. The purpose of this study was to determine the occurrence of marine mammals in eastern Indonesia in 2016. Data collection done through observation, indepth interview with the community and experts. The results of this study were 8 (eight) occurrences of marine mammals which were in Mollucas, North Mollucas and West Papua Provinces with the highest incidence in August. That marine mammals were Duyung (Dugong dugon), Sperm Whale (Physetermacrocephalus), Risso’s Dolphin (Grampus griseus), and 2 types of unidentified Whales. The marine mammals exist were deliberately netted by people, stranded, trapped in fishing nets or deliberately commercialized. This marine mammals stranded occurence indicate the requirement of strategies development for handling these protected marine ‘biota’ to store their population.

Abstract:
Currently, species identification of stranded marine mammals mostly relies on morphological features, which has inherent challenges. The use of genetic information for marine mammal species identification remains limited, therefore, new approaches that can contribute to a better monitoring of stranded species are needed. In that context, the ISSR-HRM method we have proposed offers a new approach for marine mammal species identification. Consequently, new approaches need to be developed to identify individuals at the species level. Eight primers of the ISSR markers were chosen for HRM analysis resulting in ranges of accuracy of 56.78–75.50% and 52.14–75.93% in terms of precision, while a degree of sensitivity of more than 80% was recorded when each single primer was used. The ISSR-HRM primer combinations revealed a success rate of 100% in terms of discrimination for all marine mammals included in this study. Furthermore, ISSR-HRM analysis was successfully employed in determining marine mammal discrimination among varying marine mammal species. Thus, ISSR-HRM analysis could serve as an effective alternative tool in the species identification process. This option would offer researchers a heightened level of convenience in terms of its performance and success rate. It would also offer field practice to veterinarians, biologists and other field-related people a greater degree of ease with which they could interpret results when effectively classifying stranded marine mammals. However, further studies with more samples and with a broader geographical scope will be required involving distinct populations to account for the high degree of intraspecific variability in cetaceans and to demonstrate the range of applications of this approach.

Thesis (Ph. D.)--Massachusetts Institute of Technology, Dept. of Biology, 2006.<br>"June 2006."<br>Includes bibliographical references.<br>Energy intake of individuals affects growth of organisms and, therefore, populations. Persistent lipophilic toxicants acquired with the energy can bioaccumulate and harm individuals. Marine mammals are particularly vulnerable because of their large energy requirements, and transfer of energy and toxicants from mothers to their young during gestation and lactation. Dynamic energy budget (DEB) models for energy assimilation and utilization, coupled with pharmacokinetic models that calculate distribution of toxicants in individuals, can help investigate the vulnerability. In this dissertation I develop the first individual DEB model tailored specifically to marine mammals and couple it to a pharmacokinetic model for lipophilic toxicants. I adapt the individual model to the right whale and use it to analyze consequences of energy availability on individual growth, reproduction, bioaccumulation, and transfer of toxicants between generations. From the coupled model, I create an individual-based model (IBM) of a marine mammal population. I use it to investigate how interactions of food availability, exposure to toxicants, and maternal transfer of toxicants affect populations. I also present a method to create matrix population models from a general DEB model to alleviate some of the drawbacks of the IBM approach.<br>by Tin Klanjšček.<br>Ph.D.

Abstract:
Marine mammals are in a precarious conservation position because of anthropogenic impacts and historic perceptions that they are a consumable commodity. In light of changing abiotic conditions, further evaluation is needed on the habitat use, behavior, and interactions among marine mammals. Conservation legislation has helped protect species, but the greatest ground swelling may be the advent of the commercial whale watching industry. The feeding grounds in Alaskan waters have made this area a prime tourism location, and these nutrient-rich waters have resulted in a confluence of marine mammal species, including the appealing and abundant humpback whale (Megaptera novaeangliae) that may associate with three ecotypes of killer whales (Orcinus orca). These species are interesting because they may travel together to feed on prey or be adversaries in a predator-prey relationship. Using whale watching as a platform, this study evaluated the effects of the presence of these two species separately and together, and of the type of interaction between them, on human perception. Data were collected via opportunistic observations and a retrospective pre- and post-survey instrument. Differences in humpback whale distribution and group size patterns were found relative to killer whale occurrence, although humpback whale behavioral states were unchanged. Changes in passenger conservation attitudes could not be attributed to species and behaviors but they were important determinates to whale watching satisfaction. Overall, more positive conservation attitudes and an increase in knowledge about marine mammals were reported after whale watching. These tours provide an opportunity for collecting meaningful scientific data and providing more in-depth education such as enhancing the appreciation for ecosystem services provided by marine mammals.

Abstract:
Policy-makers increasingly need to use scientific data that are imprecise. This problem is particularly apparent for marine mammal management issues, where practical research constraints leave scientists and managers with the problem of drawing inference from sparse data. Effective use of such data therefore places great demands on our methods of data analysis and statistical inference. In this thesis I introduce novel Bayesian methods for the analysis of data on marine mammal abundance and trends. Bayesian methods are applied to a suite of case studies to inform current management issues of importance both in the UK and overseas. These include estimating the probability of density dependence in the growth of a killer whale (Orcinus orca) population inhabiting the inshore waters of Washington State; estimating the size of a widespread population of bottlenose dolphins (Tursiops truncatus) in the Bahamas; and assessing the population status and abundance trends of bottlenose dolphins within a newly designated Special Area of Conservation in the Moray Firth, NE Scotland. Each of these case studies uses model-based analysis of individual photo- identification data to make inference about unknown population parameters of interest. Specifically, Bayesian inference, based on "posterior" probability distributions and statements, is used to facilitate scientific reporting in the face of uncertainty about these unknowns. Additional issues addressed are the selection of alternative statistical models for inference based on posterior model probabilities; incorporating model selection uncertainty into inference through the estimation of model-averaged parameter estimates; and the use of random effects prior distributions to model the relatedness between unknown parameters and increase estimate precision. The application of these methods is accomplished through the use of Markov chain Monte Carlo sampling methods, which are implemented using the WinBUGS software.

Abstract:
During the last decades the problems caused by anthropogenic sound and noise in oceans have been recognized in public, by governments, and military. With the use of active sonar, different choices can be made to minimize the risk of damaging or disturbing marine mammals. For this purpose knowledge of sonar disturbance is crucial. There are methods for time or area planning, i.e. when and where to use active sonars, to avoid marine mammals. The purpose of this work is to find information in literature on marine mammal behaviour reactions to the sound of sonar pings, and to evaluate which of two different behavioural models used in risk assessment programs, the “varying response” model and the “avoidance” model, is more correct to use. Main focus is on sonars and marine mammals residing in Sweden, i.e. the harbour porpoise, grey seal, harbour seal and ringed seal. Behavioral results from other research areas such as bycatch, environmental, and strandings, together with other sound sources than sonars and other species, provide a broader picture of the situation in noisy oceans. For the harbor porpoise the “avoidance” model works well. It is a very shy species, which flees fast and far when it comes in contact with new things. With the seals however the “avoidance” model is probably less good, since their responses to sonar differ rather much. Hence, for these taxa we recommend to use the “various” model that takes into account such varying responses.

Abstract:
The Texas Marine Mammal Stranding Network (TMMSN) is a valuable data resource for the marine mammal community. Limitations of funding and personnel severely impact the ability of the Network to maintain impeccable databases. This research constructed an application to address database complications and focused on investigating the species identification, temporal and spatial trends for stranding events along the Texas coast. From 1980 to 2004, Tursiops truncatus accounted for approximately 80% of all stranding events. The remainder was 20 additional whale and dolphin species known to reside in the Gulf of Mexico. Tursiops truncatus strand along the entire coastline and are the only species stranding in the bays. All other species stranding are most dense along the southern coastline. The temporal scales of events revealed no linear patterns from 1980 to 2004. A unique cyclic fluctuation occurred from 1992 to 1998, including the highest yearly counts and one isolated mortality event in Port Aransas. Attempts to forecast stranding events beyond 2004 were inconclusive due to multiple factors influencing a stranding event. A bimodal seasonal trend was evident, with events peaking in the spring and fall months. Density distributions by decade isolated three frequent stranding areas: Sabine-Galveston-Brazoria counties, Galveston Shipping Channel, and Corpus Christi Shipping Channel. The final aspect analyzed spatial elaboration of events by creating six location values to describe the Texas coastline. Each event was assigned from the geographical location and the orientation of an event along the coastline. Analysis revealed the segregation of Tursiops truncatus in the bays and confirmed earlier results of density distributions. Examining the locations by time revealed a specific incident connected to a mortality event in 1992, accounting for 59% of the stranding events. Location categories were compared to the TMMSN stranding regions and the regions experienced different location frequencies. This study demonstrated how to construct a stronger database and the necessity for database accuracy. Study conclusions demonstrated the need to better isolate and research factors responsible for event distributions in time and space along the Texas coast to forecast the magnitude and location of stranding events to better aid the TMMSN response efforts.

Abstract:
CIVINS<br>Approved for public release, distribution unlimited<br>Marine mammal whistle calls present an attractive medium for covert underwater communications. High quality models of the whistle calls are needed in order to synthesize natural-sounding whistles with embedded information. Since the whistle calls are composed of frequency modulated harmonic tones, they are best modeled as a weighted superposition of harmonically related sinusoids. Previous research with bottlenose dolphin whistle calls has produced synthetic whistles that sound too clean for use in a covert communications system. Due to the sensitivity of the human auditory system, watermarking schemes that slightly modify the fundamental frequency contour have good potential for producing natural-sounding whistles embedded with retrievable watermarks. Structured total least squares is used with linear prediction analysis to track the time-varying fundamental frequency and harmonic amplitude contours throughout a whistle call. Simulation and experimental results demonstrate the capability to accurately model bottlenose dolphin whistle calls and retrieve embedded information from watermarked synthetic whistle calls.

Abstract:
A floating object's drift is governed by its buoyancy, shape, and the wind, waves and currents it experiences. Here, I develop a drift modelling framework for marine mammal carcases in coastal waters. The resulting models were run forwards and backwards in time to provide insights into strategies for environmental monitoring under two scenarios. The first explored the beach search options for carcases resulting from potentially fatal collisions between tidal-stream turbines and marine mammals. The second applied the reverse problem for known-location mass strandings to highlight potential at-sea mortality sites. The drift properties of carcase-like objects were assessed in at-sea experiments. Wave transport was found to be greater than Stokes drift alone and in a complex coastal area could not be represented by a downwind multiplier as many previous models have assumed. A high resolution unstructured grid wave model was set up to complement existing wind and current models for the West Coast of Scotland, and these components were combined to build a carcase drift model. In the forward case, from tidal turbine locations, the drift model showed a wide spread of potential stranding sites, suggesting monitoring a limited number of beaches is unlikely to be fruitful. However, selecting beaches in response to immediate wind direction would improve efficiency. Stranding locations alone can only provide evidence of turbine interactions if the number of animals affected is large. In the reverse case, when applied to a mass stranding in Chile, the drift model showed the ability to exclude areas of origin, even though it could not pinpoint an exact mortality site. This work advances understanding of wave transport of surface floating objects, of carcase drift modelling, and of the feasibility of strandings monitoring. The decomposition rate of carcases is a source of uncertainty in the model where further work should be undertaken.

Abstract:
This study aimed to provide scientific information on the status of marine mammals and threats from directed takes and incidental catches in fisheries in East Malaysia. Recommendations for the conservation of the animals and guidelines for further research are also provided. All available information on sightings, strandings, skeletal remains and threats to the marine mammals in East Malaysia prior to this study were reviewed.  A series of broad and aerial sighting surveys was conducted in the marine and fluvial waters.  The objective was to explore and observe marine mammals at sea, and to describe the present species composition, distribution and density. In conclusion, this study showed that marine mammals in East Malaysian waters are diverse. Dugongs and small citations are facing threats from by-catches in fisheries, declining fisheries resources, habitat loss and degradation, pollution, heavy vessel traffic and rapid urban and industrial development along its coastline.  In Sabah, traditional hunting for meat, illegal trawling in estuarine and riverine waters, and dynamite fishing are particularly detrimental to the species and their habitats.  Without an immediate, committed and concerted effort to educate the public, monitor fisheries, enforce conservation laws and conduct detailed assessment of the dugong and small cetacean populations and their habitats, there may be little hope to reduce or eliminate the threats and to maintain their present numbers in the waters of East Malaysia.

Full text
Abstract:
While most mammals shed their hair and skin either continuously or seasonally, northern elephant seals (Mirounga angustirostris) undergo an annual catastrophic molt, in which they shed their entire fur and underlying skin layer in the span of just three weeks. Due to the energetic and thermoregulatory constraints of molting and the large distances between their coastal rookeries and foraging grounds, elephant seals must remain on land and fast for the duration of their molt. Previous studies of molting northern elephant seals have examined endocrine and metabolic adjustments to fasting, but not the molecular processes underlying molting. We examined changes in the skin and underlying blubber tissues using histological, endocrine, and proteomic analyses during molting to provide a more in-depth understanding of the cellular mechanisms enabling rapid skin shedding and regeneration in this marine mammal. Shotgun proteome sequencing by LC-MS/MS identified 47,671 peptides and 573 protein groups in skin and outer blubber that were associated with lipid metabolism, protein processing in the endoplasmic reticulum, and collagen regulation. Label-free quantification and differential protein expression analyses identified 23 and 21 proteins that were differentially expressed during molting in the skin and outer blubber, respectively. Proteins downregulated over molting included those associated with inflammation, angiogenesis, and cellular proliferation, whereas proteins upregulated over molting included those associated with cytoskeletal remodeling, collagen synthesis, and lipid metabolism. This suggests that rapid skin regeneration involves intensive protein synthesis and increased vascularization that may be supported by fatty acid substrates from underlying blubber tissue. These data provide insights into cellular and molecular mechanisms that govern unusually rapid skin regeneration in mammals, which may further understanding of disorders affecting the skin and hair of humans and other mammals.

Abstract:
AbstractBioacoustics combines the fields of biology and acoustics to answer questions about hearing, sound production and sound communication in animals. Marine mammals have specialised hearing abilities and use sounds in different ways underwater. How do whales and seals use sound for communication and to find prey? How are they affected by human-made sounds from ships, oil exploration and windfarms? To answer such questions, you need to study marine mammals, be well-trained in natural sciences and know about animal anatomy, physiology and behaviour. You also need a thorough understanding of the fundamentals of acoustics, maths and physics. Bioacoustics is a truly interdisciplinary research field involving biologists, physicists and engineers trying to understand the world of biological sound, how sounds are produced and used by animals. Additionally, underwater acoustic recordings can reveal which areas animals use during different seasons. Bioacoustics can also be used to improve wildlife protection by regulating damaging sound sources in marine mammal habitats. Using the exercises at the end of this chapter, students learn about frequencies, decibels and their own hearing abilities, as well as how to build their own underwater microphone.

Abstract:
Abstract Primary blast injury (PBI), which relates gross blast-related trauma or traces of injury in air-filled tissues or those tissues adjacent to air-filled regions (rupture/lesions, contusions, hemorrhaging), has been documented in a number of marine mammal species after blast exposure [1, 2, 3]. However, very little is known about marine mammal susceptibility to PBI except in rare cases of opportunistic studies. As a result, traditional techniques rely on analyses using small-scale terrestrial mammals as surrogates for large-scale marine mammals. For an In-house Laboratory Independent Research (ILIR) project sponsored by the Office of Naval Research (ONR), researchers at the Naval Undersea Warfare Center, Division Newport (NUWCDIVNPT), have undertaken a broad 3-year effort to integrate computational fluid-structure interaction techniques with marine mammal anatomical structure. The intent is to numerically simulate the dynamic response of a marine mammal thoracic cavity and air-filled lungs to shock loading, to enhance understanding of marine mammal lungs to shock loading in the underwater environment. In the absence of appropriate test data from live marine mammals, a crucial part of this work involves code validation to test data for a suitable surrogate test problem. This research employs a surrogate of an air-filled spherical membrane structure subjected to shock loading as a first order approximation to understanding marine mammal lung response to underwater explosions (UNDEX). This approach incrementally improves upon the currently used one-dimensional spherical air bubble approximation to marine mammal lung response by providing an encapsulating boundary for the air. The encapsulating structure is membranous, with minimal simplified representation not accounting for marine mammal species-specific and individual animal differences in tissue composition, rib mechanics, and mechanical properties of interior lung tissue. NUWCDIVNPT partnered with the Naval Submarine Medical Research Laboratory (NSMRL) to design and execute a set of experiments to investigate the shock response of an air-filled rubber dodgeball in a shallow underwater environment. These tests took place in the 2.13 m (7-ft) diameter pressure tank at the University of Rhode Island, with test measurements including pressure data and digital image correlation (DIC) data captured with high-speed cameras in a stereo setup. The authors developed 3-dimensional computational models of the dodgeball experiments using Dynamic System Mechanics Advanced Simulation (DYSMAS), a Navy fluid-structure interaction code. DYSMAS models of a variety of different problems involving submerged pressure vessel structures responding to hydrostatic and/or UNDEX loading have been validated against test data [4]. Proper validation of fluid structure interaction simulations is quite challenging, requiring measurements in both the fluid and structure domains. This paper details the development of metrics for comparison between test measurements and simulation results, with a discussion of potential sources of uncertainty.
