by Lara Delgado 11 Dec '14

11 Dec '14

Dear all, Positions are open for assisting with a cetacean survey in the Mediterranean Sea (Barcelona-Mallorca), Spain. Dates from 22nd of July to 30th of July 2011. DESCRIPTION: The EDMAKTUB association for the study and disclosure of aquatic environments, specially focused in the study of cetaceans; offer positions for volunteers for one of the trips of the summer campaign of the project “Cetacean population study of the Mediterranean Sea area: Barcelona-Balearic Islands, BCNCET 2010-2011”. The aim of the project is to study the cetacean species present in the Mediterranean Sea (Balearic Sea). The association catamaran will set sail to Mallorca, from the Barcelona port the 22nd of July and be back to Barcelona the 30th of July, both days included. Visual and acoustical surveys will be conducted from early morning to evening during the 9 days in the boat, studying the distribution, behaviour, and sound production of the sighted species. The assistants would be able to learn: species identification, environmental and behavioural data collection, sound collection, and basic marine navigating skills. Accommodation and food is offered in the catamaran during the 9 days, but assistants are required to pay 400€ for food and accommodation expenses. No previous experience is required, as the scientist present in the campaign will provide species identification information and teach assistants. If you are interested or want more information, please contact us to: edmaktub(a)edmaktub.com Thanks! EDMAKTUB association for the study and disclosure of the aquatic environment. www.edmaktub.com

Research partnerships
by Marcos Santos 31 Aug '13

31 Aug '13

Dear Marmamers: The University of Sao Paulo (USP), Brazil, established a new office in Boston, US. The aims are to contribute to strengthening mutually beneficial relations with scientists among the US, Canada, Mexico, the Caribbean and Brazil (represented by the USP). At this moment, our representatives are looking for potential partners. As the coordinator of a Laboratory devoted towards marine mammal research and conservation in southeastern Brazil, I wonder if there is any Marine Mammal Lab. coordinator, or anyone enrolled in a University, who has the interest in investing in a research partnership. One of our priorities is to find someone interested in conducting a post doctoral investigation in passive acoustics monitoring. Opportunities are great and background is necessary. The aims are to start in early to mid-2014. I’ll be attending the next SMM Biennial Conference in New Zealand, where I could talk personally with the interested ones. Contacts can be made with Dr. Marcos Santos at mcos(a)usp.br.

Publication: Genetic variation and reproductive success in right whales
by Timothy Frasier 30 Aug '13

30 Aug '13

We are pleased to announce the publication of our paper describing how fertilization patterns in North Atlantic right whales are biased towards genetically dissimilar gametes. The short-term implication is that this process may be partially responsible for the reduced reproductive performance of this species, but in the long-term it has resulted in a slight increase in heterozygosity in calves born throughout the study period. Thus, it appears to be a double-edged sword in terms implications, depending on if you look at it from a short- or long-term scale. This was the subject of my "speed talk" at the last Society for Marine Mammalogy conference (in Florida). It is published in the Open Access journal Ecology and Evolution, and should therefore be free for all.

New publication
by Denise Risch 30 Aug '13

30 Aug '13

We are pleased to announce the following paper: Risch D, Clark CW, Dugan PJ, Popescu M, Siebert U, Van Parijs SM (2013) Minke whale acoustic behavior and multi-year seasonal and diel vocalization patterns in Massachusetts Bay, USA. Mar Ecol Prog Ser 489:279-295 The pdf can be accessed online or via email request: denise.risch(a)noaa.gov Abstract Passive acoustic monitoring (PAM) is a rapidly growing field, providing valuable insights in marine ecology. The approach allows for long-term, species-specific monitoring over a range of spatial scales. For many baleen whales fundamental information on seasonal occurrence and distribution is still missing. In this study, pulse trains produced by the North Atlantic minke whale, a highly mobile and cryptic species, are used to examine its seasonality, diel vocalization patterns and spatial distribution throughout the Stellwagen Bank National Marine Sanctuary (SBNMS), USA. Three and a half years (2006, 2007 to 2010) of near continuous passive acoustic data were analyzed using automated detection methods. Random forests and cluster analyses grouped pulse trains into 3 main categories (slow-down, constant and speed-up), with several sub-types. Slow-down pulse trains were the most commonly recorded call category. Minke whale pulse train occurrence was highly seasonal across all years. Detections were made from August to November, with 88% occurring in September and October. No detections were recorded in January and February, and only few from March to June. Minke whale pulse trains showed a distinct diel pattern, with a nighttime peak from approximately 20:00 to 01:00 h Eastern Standard Time (EST). The highest numbers of pulse trains were detected to the east of Stellwagen Bank, suggesting that minke whales travel preferably in deeper waters along the outer edge of the sanctuary. These data show that minke whales consistently use Stellwagen Bank as part of their migration route to and from the feeding grounds. Unlike other baleen whales in this area they do not appear to have a persistent year-round acoustic presence.

Two new papers on metabolism/energetics of Pacific white-sided dolphins
by Erin Rechsteiner 29 Aug '13

29 Aug '13

Dear colleagues, We are pleased to announce the following two papers which have recently been published. Rechsteiner EU, Rosen DAS, & Trites AW. Seasonal resting metabolic rate and food intake of captive Pacific white-sided dolphins (*Lagenorhynchus obliquidens*). Aquatic Mammals 39(3) 241-252 * * *Abstract.** *Like many marine mammals, Pacific white-sided dolphins (*Lagenorhynchus obliquidens*) consume prey that change seasonally in numbers, distribution, and energy density. However, it is not known whether these ecological factors are associated with underlying seasonal changes in energy requirements. We investigated these potential seasonal shifts in physiology by measuring resting metabolic rate (a conserved physiological trait) and recording associated daily food energy intake of three captive adult Pacific white-sided dolphins over 12 consecutive months. Two dolphins that met the criteria for measuring resting metabolism had a mean (± SE) mass- specific rate of 0.31 ± 0.0047 MJ kg-1 day-1 (~34 MJ day-1), which was higher than that of other species of small cetaceans. Resting metabolic rates of Pacific white-sided dolphins did not vary seasonally and, hence, were not related to observed seasonal changes in water or air temperature, total energy intake, or body mass. Overall, resting metabolism accounted for ~70% of total energy intake. However, total food energy intake changed seasonally and was highest during the fall (October to December). While levels of food intake were not predicted by resting metabolic rate, body mass, or water and air temperatures, the increased intake in the fall resulted in the seasonal increase in body mass exhibited by all three dolphins. Our estimates of resting metabolic rates and relative changes in total energy intake can be used to parameterize bioenergetic models needed to estimate the ecological impacts and energetic requirements of Pacific white-sided dolphins in the wild, which will have conservation implications. and Rechsteiner EU, Rosen DAS, & Trites AW. Energy requirements of Pacific white-sided dolphins (*Lagenorhynchus obliquidens*) as predicted by a bioenergetic model. Journal of Mammalogy. 94(4) 820-832 *Abstract. *Apex predators such as Pacific white-sided dolphins (*Lagenorhynchus obliquidens*) have the potential to impact prey populations and to be affected by changes in prey abundance. As abundant predators that range widely across the North Pacific Ocean, their interactions with prey populations may have conservation implications. The energy required by individual Pacific white-sided dolphins was estimated using a bioenergetic model that accounted for different age classes and reproductive stages (calf, juvenile, adult, pregnant, and lactating). Monte Carlo simulations incorporating variability in model parameters (i.e., body mass, growth rate, costs of gestation and lactation, metabolic rate, cost of activity, and assimilation efficiencies) were used to predict ranges in energetic requirements of this species. Mean (*+* SD) total energy requirements in MJ/day were 40.3 *+* 6.2 for calves, 70.8 *+* 8.2 for juveniles, 69.0 *+* 3.6 for adults, 70.3 *+* 3.6 for pregnant females, and 98.4 *+* 20.0 for lactating females. Estimates of energy requirements were most sensitive to uncertainty in values used for resting metabolic rates and energetic costs of activity. Estimated mass-specific energy requirements in MJ kg -1 day -1 were elevated in calves (1.55 *+* 0.23), juveniles (0.97 *+* 0.11), and lactating females (1.01 *+* 0.21) when compared with non-reproductive adults and pregnant females (~0.71 *+* 0.04). Based on a high-energy diet, an average-sized dolphin (78 kg) would consume approximately 12.5–15.8 kg of fish or 16–20% of its body mass per day. These high energetic requirements may indicate a reliance of dolphins on energy-rich prey, which has implications for fisheries management and conservation of marine mammals. Both articles are available online on the journal websites (Aquatic Mammals, Journal of Mammalogy).

New Paper on Gray Seal Behaviour in England
by Amy Bishop 29 Aug '13

29 Aug '13

Dear subscribers, We are pleased to announce the following publication on the use of a newly described Body Slapping behaviour performed by male gray seals in England. To the best of our knowledge the behaviour investigated in the article has only been seen performed along the eastern coast of England, but we would love to hear if anyone has observed this behaviour elsewhere in the gray seal range. Bishop, A. M., Lidstone-Scott, R., Pomeroy, P. and Twiss, S. D. (2013), Body slap: An innovative aggressive display by breeding male gray seals (*Halichoerus grypus*). Marine Mammal Science. doi: 10.1111/mms.12059 *ABSTRACT* Aggression in male gray seals has been extensively studied; however it is often simplistically assumed that threat signals are mainly cephalic in nature for this species. We report on an undescribed and apparently new kind of threat signal used by male gray seals we term a Body Slap. The behavior has been observed at breeding sites in eastern England since 1993 but has not been studied ethologically or reported elsewhere. The aims of this study were to describe the behavior, test the influence of topographic variation on its frequency of occurrence, examine if it is used to signal dominance or submission, and to place it in intra- and interspecific contexts. Our results show Body Slaps were performed in 66.3% of interactions and by 57.2% of males; it was not performed by females. The Body Slap was positively associated with the Approach and Open-Mouth Threat behaviors but was not related to dominance; nevertheless, display rates were greater for subsequent winners. These findings suggest that the Body Slap carries information about male resource holding potential and does not signal submission. This study furthers our understanding of geographic variants of male threat behaviors and of pinniped nonvocal communication. The article and supplemental video can be downloaded/viewed directly on the Marine Mammal Science website: http://onlinelibrary.wiley.com/doi/10.1111/mms.12059/full<https://owa.dur.ac.uk/owa/redir.aspx?C=OOwR-wfERUSXEGS-3YZAhDs6Wc0xeNAI0qxc…> Or you may contact me for a pdf at a.m.bishop(a)durham.ac.uk Kind regards, Amy Bishop ______________________________________ PhD Student Durham University School of Biological and Biomedical Sciences Durham UK DH1 3LE +44 (0) 1913341247 website: sealbehaviour.wordpress.com email: a.m.bishop(a)dur.ac.uk
