New Publication: Annual, seasonal, and diel patterns in blue whale call occurrence off eastern Canada
by Bette Rubin 28 Dec '22

28 Dec '22

Dear MARMAM community, My co-authors and I are pleased to share our recent publication, published in *Endangered Species Research*: Citation: Wingfield, J.E., Rubin, B., Xu, J., Stanistreet, J.E., Moors-Murphy, H.B. (2022). Annual, seasonal, and diel patterns in blue whale call occurrence off eastern Canada. Endang. Species Res. 49:71-86. Abstract: Little is known about the year-round occurrence of blue whales in Atlantic Canadian waters. We used passive acoustic monitoring to investigate blue whale call presence and increase our understanding of year-round blue whale occurrence along the eastern edge of the Scotian Shelf, Nova Scotia, Canada. Blue whale calls were recorded at 3 deep water sites within and near the Gully Marine Protected Area from October 2012 to September 2014 using bottom-mounted passive acoustic recorders. Calls were categorized as either tonal or downsweeping. At all 3 sites, tonal calls occurred most often from November through January in both years and in August 2014, while the majority of downsweeping calls occurred during May through September 2014. There was no discernible diel pattern in the occurrence of tonal calls. Downsweeping calls occurred most often during evening twilight, with a dramatic peak in occurrence during the hour of 19:00 Atlantic Standard Time at all 3 sites. The peak in downsweeping call occurrence during evening twilight may have been related to blue whale foraging ecology. This study sheds light on the poorly understood year-round occurrence of blue whales off Atlantic Canada. Understanding when and where blue whales occur will help to inform management decisions for the protection and conservation of this endangered population.

New publication: Using a consumer drone for the collection of humpback whale blow samples during the Arctic polar nights
by Helena Costa 26 Dec '22

26 Dec '22

Dear all, My co-authors and I are pleased to share our recent communication “Blowing in the Wind: Using a Consumer Drone for the Collection of Humpback Whale (Megaptera novaeangliae) Blow Samples during the Arctic Polar Nights”. Costa, H.; Rogan, A.; Zadra, C.; Larsen, O.; Rikardsen, A.H.; Waugh, C. Blowing in the Wind: Using a Consumer Drone for the Collection of Humpback Whale (Megaptera novaeangliae) Blow Samples during the Arctic Polar Nights. Drones 2023, 7, 15. https://doi.org/10.3390/drones7010015 Abstract: Analysis of cetacean blow offers a unique potential for non-invasive assessments of their health. In recent years, the use of uncrewed aerial vehicles (UAVs) has revolutionized the way these samples are collected. However, the high cost and expertise associated with purpose-built waterproof UAVs, paired with the challenges of operating during difficult meteorological conditions, can be prohibitive for their standardized use worldwide. A pilot study was conducted in a Northern Norwegian fjord during winter, to assess the feasibility of using a minimally modified and affordable consumer drone to collect blow samples even during the polar nights’ challenging weather conditions. For each flight, six petri dishes were attached with velcro to a DJI Mavic 2 Pro. The flights were conducted under temperatures ranging from -1 to -18 degrees Celsius, wind speeds ranging from 9 to 31 km/h, and with the absence of the sun. During the 6-day-long boat survey, 16 blow samples were successfully collected from 11 distinct groups of humpback whales (Megaptera novaeangliae). With this study, we further validated the use of a consumer drone as a practical, affordable, and simplified tool for blow collection, functional under harsh meteorological conditions.

Please also send me an email at marinebrit(a)gmail.com for a copy if you don't have access. All the best for the holidays, Andrew Andrew J. Wright & Hilary B. Moors-Murphy 2022. Regulating Impacts of Noise on Marine Mammals in North America: An Overview of the Legal Frameworks in Canada and the United States. Journal of International Wildlife Law & Policy. https://doi.org/10.1080/13880292.2022.2151116 https://www.tandfonline.com/doi/full/10.1080/13880292.2022.2151116?src= Abstract: Marine mammals are protected under dedicated taxonomic legislation, endangered species legislation, and general environmental stewardship laws in many countries. Governments and agencies within those countries are tasked with assessing and limiting human impacts in accordance with their own laws, including those arising from underwater noise emissions. While the United States (US) has established thresholds for permanent and temporary threshold shifts (PTS and TTS) in the hearing of marine mammals, Canada has not yet established specific numeric onset thresholds for hearing impairment or other noise-related impacts. Given that Canada and the US are jointly responsible for the management of a number of at-risk marine mammals, we provide a brief overview of the main laws and associated standards relevant to management of noise impacts on marine mammals in these two jurisdictions. The US PTS/TTS thresholds are only a small part of a suite of elements collectively applied to assess and mitigate the full range of impacts of noise on marine mammals, and the implementation of these (or any other) thresholds in Canada would not negate the need to conduct case-specific impact assessments to satisfy their own broader requirements. Caution should be taken when applying US thresholds to address Canadian legal standards, as there are substantial differences in the legal definitions to which these thresholds might be applied. Thus, the need for, and application of, similar generalised PTS/TTS thresholds in Canada is still under debate and noise impacts will likely continue to be assessed in different ways in these two bordering nations.

Canadian Journal of Zoology, https://doi.org/10.1139/cjz-2022-0085 https://cdnsciencepub.com/doi/10.1139/cjz-2022-0085 Abstract: Technical Guidance from the U.S. National Marine Fisheries Service recommends Federal agencies use estimated thresholds for peak sound pressure levels and weighted cumulative sound exposure levels for the onset of permanent (and temporary) hearing threshold shifts in marine mammals. These dual metrics were developed to inform impact assessments within the U.S. legal landscape. Despite its merits, the Technical Guidance contains uncertainties due to a lack of data on marine mammal hearing and auditory response to noise, the underlying assumptions about the representative value of existing data create limitations in the applicability of the Technical Guidance. These limitations warrant consideration before it can be applied effectively in other jurisdictions with different legal standards. Using the Canadian legal framework as a working example, we found that Canadian species are under-represented in the dataset used for the Technical Guidance, which also does not address all relevant impact types to meet the precautionary requirements of many Canadian legal standards. Thus, the Technical Guidance alone cannot address all Canadian legal standards and, if the Guidance is incorporated, some adjustments to the criteria within may be needed. -- Andrew Wright, Ph.D. VaquitaAreBrowncoats: Where Sci-Fi meets Science, the Cosmos meets Conservation and Firefly meets Flipper.

New Publication: Occurrence, site fidelity, and abundance of bottlenose dolphins (Tursiops truncatus) in the Western Ligurian Sea
by Davide Ascheri 22 Dec '22

22 Dec '22

Dear all, My co-authors and I are pleased to share the publication our recent publication: Occurrence, site fidelity, and abundance of bottlenose dolphins (*Tursiops truncatus*) in the Western Ligurian Sea, Italy, published in the Journal of Cetacean Research and Management. Ascheri, D., Fontanesi, E., Ballardini, M., Nani, B. and Allessi, J. 2022. Occurrence, site fidelity, and abundance of bottlenose dolphins (*Tursiops truncatus*) in the Western Ligurian Sea. *J. Cetacean Res. Manage. *23: 191-204. Abstract: This study represents the first complete assessment of the population dynamics and residency of common bottlenose dolphins in the Western Ligurian Sea, an area where bottlenose dolphin sightings have been rare in the past. Despite being greatly affected by human pressure, information about this population is poor and sporadic. The study took place from April 2018 to December 2020. One hundred and seventy‐one dedicated boat surveys were performed year‐round resulting in 95 sightings, and 123 individuals were identified through mark‐recapture photo‐identification techniques. Dolphins were found to be present year‐round. Most of the animals (79) used the area sporadically and only 19.5% of the dolphins (24) were seen regularly. Bottlenose dolphin abundance was estimated at 248 using open POPAN population models (CI 95% = 217–284). These results help fill a knowledge gap by highlighting the regular presence of bottlenose dolphins in the study area. Moreover, they represent a baseline for future studies investigating abundance trends and the conservation status of this population.

New publication: Foraging segregation in South American fur seal and South American sea lions in Peru
by Susana Cardenas 22 Dec '22

22 Dec '22

Hello MARMAM members, My co-authors and I are pleased to announce our recent publication "Strategies for segregation during foraging in sympatric otariids of the Peruvian upwelling Humboldt Current System" https://doi.org/10.3354/meps14203 Abstract The competitive exclusion principle predicts that species exhibit segregation mechanisms to coexist. In the Humboldt Current System, South American sea lions Otaria byronia (SASL) coexist with South American fur seals Arctocephalus australis (SAFS); however, the existence of temporal and spatial partitioning in foraging strategies remains unknown. To compare foraging strategies, we analyzed locations of 35 adults (18 SASL, 17 SAFS; 4 and 8 females, 14 and 9 males, respectively) equipped with satellite tags in Punta San Juan, Peru (2013-2017). We evaluated (1) distance and duration of foraging trips, (2) utilization distributions (UDs), (3) foraging by hour and (4) association of foraging with environmental variables. Regular interval tracks (every 30 min) were modeled, and residence time was estimated to determine foraging events. Proportion overlap and analysis of similarity compared groups in core areas (50% UD) and home ranges (95% UD). Generalized additive mixed models were built to determine if hour of day and environmental conditions had an effect on foraging. Multiple mechanisms for foraging segregation that explain coexistence were found. Duration and distance between species-sex groups were significantly different, except for trip duration between SASL sexes. SAFS traveled longer distances and duration than SASL, and males traveled longer distances and duration than conspecific females. Female UDs overlapped, while male UDs did not. Core areas between sexes overlapped in SAFS and SASL, but home ranges were significantly different. Hour of day had a significant effect on foraging events in SAFS females and SASL males. Environmental conditions during foraging by SASL and SAFS females reflected coastal and offshore habitats, respectively. However, interspecific segregation was not evident between males.

New publication: An epigenetic DNA methylation clock for age estimates in Indo-Pacific bottlenose dolphins (Tursiops aduncus)
by Katharina Peters 21 Dec '22

21 Dec '22

Kia ora MARMAM community, My colleagues and I are very happy to share the publication of our new paper: ‘An epigenetic DNA methylation clock for age estimates in Indo-Pacific bottlenose dolphins (Tursiops aduncus)’ in Evolutionary Applications. Citation: Peters, K. J., Gerber, L., Scheu, L., Cicciarella, R., Zoller, J. A., Fei, Z., Horvath, S., Allen, S. J., King, S. L., Connor, R. C., Rollins, L. A., & Krützen, M. (2022). An epigenetic DNA methylation clock for age estimates in Indo-Pacific bottlenose dolphins (Tursiops aduncus). Evolutionary Applications, 00, 1– 8. Abstract: Knowledge of an animal's chronological age is crucial for understanding and predicting population demographics, survival and reproduction, but accurate age determination for many wild animals remains challenging. Previous methods to estimate age require invasive procedures, such as tooth extraction to analyse growth layers, which are difficult to carry out with large, mobile animals such as cetaceans. However, recent advances in epigenetic methods have opened new avenues for precise age determination. These ‘epigenetic clocks’ present a less invasive alternative and can provide age estimates with unprecedented accuracy. Here, we present a species-specific epigenetic clock based on skin tissue samples for a population of Indo-Pacific bottlenose dolphins (Tursiops aduncus) in Shark Bay, Western Australia. We measured methylation levels at 37,492 cytosine-guanine sites (CpG sites) in 165 samples using the mammalian methylation array. Chronological age estimates with an accuracy of ±1 year were available for 68 animals as part of a long-term behavioral study of this population. Using these samples with known age, we built an elastic net model with Leave-One-Out-Cross-Validation, which retained 43 CpG sites, providing an r = 0.86 and median absolute age error (MAE) = 2.1 years (5% of maximum age). This model was more accurate for our data than the previously published methylation clock based on skin samples of common bottlenose dolphins (T. truncatus: r = 0.83, MAE = 2.2) and the multi-species odontocete methylation clock (r = 0.68, MAE = 6.8), highlighting that species-specific clocks can have superior performance over those of multi-species assemblages. We further developed an epigenetic sex estimator, predicting sex with 100% accuracy. As age and sex are critical parameters for the study of animal populations, this clock and sex estimator will provide a useful tool for extracting life history information from skin samples rather than long-term observational data for free-ranging Indo-Pacific bottlenose dolphins worldwide.
