8 April 2021 Mr. Jon Kurland Assistant
8 April 2021 Mr. Jon Kurland Assistant Regional Administrator Protected Resources Division, Alaska Region National Marine Fisheries Service P.O. Box 21668 Juneau, Alaska 99082-1668 Dear Mr. Kurland: The Marine Mammal Commission (the Commission), in consultation with its Committee of Scientific Advisors on Marine Mammals, has reviewed the National Marine Fisheries Service’s (NMFS) 8 January 2021 Federal Register notice (86 Fed. Reg. 1452) revising its proposed designation of critical habitat for Arctic ringed seals (Phoca hispida hispida)1 and reopening the comment period on that proposal. The Commission offers the following comments and recommendations. Background On 28 December 2012, NMFS published a final rule listing the Arctic ringed seal as threatened under the Endangered Species Act (ESA) (77 Fed. Reg. 76706) and requesting information on physical and biological features essential to the conservation of Arctic ringed seals and on economic consequences of designating critical habitat for this species. Section 3(5)(A) of the ESA defines “critical habitat” as: (i) the specific areas within the geographical area occupied by the species, at the time it is listed in accordance with section 4 of this Act, on which are found those physical or biological features (I) essential to the conservation of the species and (II) which may require special management considerations or protection; and (ii) specific areas outside the geographical area occupied by the species at the time it is listed in accordance with the provisions of section 4 of this Act, upon a determination by the Secretary that such areas are essential for the conservation of the species. -

List of Marine Mammal Species & Subspecies
List of Marine Mammal Species & Subspecies The Committee on Taxonomy, chaired by Bill Perrin, produced the first official Society for Marine Mammalogy list of marine mammal species and subspecies in 2010 . Consensus on some issues was not possible; this is reflected in the footnotes. The list is updated annually. This version was updated in October 2015. This list can be cited as follows: “Committee on Taxonomy. 2015. List of marine mammal species and subspecies. Society for Marine Mammalogy, www.marinemammalscience.org, consulted on [date].” This list includes living and recently extinct (within historical times) species and subspecies, named and un-named. It is meant to reflect prevailing usage and recent revisions published in the peer-reviewed literature. An un-named subspecies is included if author(s) of a peer-reviewed article stated explicitly that the form is likely an undescribed subspecies. The Committee omits some described species and subspecies because of concern about their biological distinctness; reservations are given below. Author(s) and year of description of the species follow the Latin species name; when these are enclosed in parentheses, the species was originally described in a different genus. Classification and scientific names follow Rice (1998), with adjustments reflecting more recent literature. Common names are arbitrary and change with time and place; one or two currently frequently used names in English and/or a range language are given here. Additional English common names and common names in French, Spanish, Russian and other languages are available at www.marinespecies.org/cetacea/. Species and subspecies are listed in alphabetical order within families. -

The Ladoga Ringed Seal (Pusa Hispida Ladogensis) Under Changing Climatic Conditions
Russian J. Theriol. 12(1): 4148 © RUSSIAN JOURNAL OF THERIOLOGY, 2013 The Ladoga ringed seal (Pusa hispida ladogensis) under changing climatic conditions Irina S. Trukhanova ABSTRACT. The Ladoga ringed seal is a Red listed subspecies of ringed seal, which most critical life cycle stages are closely related to ice presence on the lake. Climatic changes which are observed globally have their impact on local marine mammal populations resulting in shifts in distribution, abundance, migration pattern, disease occurrence, reproductive success. We considered trends in various ice related parameters on the Lake Ladoga since mid-XX century in relation to possible consequences to the Ladoga seal population. Analysis of the probability of winter with 100% ice coverage of the lake showed a statistically significant negative trend. Similarly, negative, though rather weak, trends were observed for sum of negative temperatures in the region and average ice thickness. The total duration of the ice period on the lake has reduced by 13.7% during the second part of the XX century. Maintenance of such trends, though non-significant on short term scale, can cause stress reactions in the Ladoga ringed seal living at the very southern edge of the species global range.

EDEN: Deep Feature Distribution Pooling for Saimaa Ringed Seals Pattern Matching Ilia Chelak12, Ekaterina Nepovinnykh2, Tuomas Eerola2, Heikki K¨alvi¨ainen2, and Igor Belykh1 1 Peter the Great St. Petersburg Polytechnic University, Saint Petersburg, Russian Federation [email protected], [email protected], 2 Lappeenranta-Lahti University of Technology LUT, School of Engineering Science, Department of Computational Engineering, Computer Vision and Pattern Recognition Laboratory, P.O.Box 20, 53850 Lappeenranta, Finland [email protected] Abstract. In this paper, pelage pattern matching is considered to solve the individual re-identification of the Saimaa ringed seals. Animal re- identification together with the access to large amount of image material through camera traps and crowd-sourcing provide novel possibilities for animal monitoring and conservation. We propose a novel feature pool- ing approach that allow aggregating the local pattern features to get a fixed size embedding vector that incorporate global features by tak- ing into account the spatial distribution of features. This is obtained by eigen decomposition of covariances computed for probability mass func- tions representing feature maps. Embedding vectors can then be used to find the best match in the database of known individuals allowing ani- mal re-identification. The results show that the proposed pooling method outperforms the existing methods on the challenging Saimaa ringed seal image data. Keywords: pattern matching, global pooling, animal biometrics, Saimaa ringed seals 1 Introduction Automatic camera traps (game cameras) and crowd-sourcing provide tools for collecting large volumes of image material to monitor and to study wildlife an- imals.

21 August 2017 Ms. Angela Somma, Chief Endangered Species
21 August 2017 Ms. Angela Somma, Chief Endangered Species Conservation Division Office of Protected Resources National Marine Fisheries Service 1315 East-West Highway, Room 13535 Silver Spring, MD 20910 ATTN: Ron Dean Dear Ms. Somma: The Marine Mammal Commission (the Commission) has reviewed the National Marine Fisheries Service (NMFS) request for information regarding the endangered baiji/Chinese river dolphin/Yangtze River dolphin (Lipotes vexillifer) and endangered Saimaa subspecies of ringed seal (Phoca hispida saimensis)1 for use in its five-year review of their respective statuses under the Endangered Species Act (ESA) of 1973, as amended (82 Fed. Reg. 28304). The announcement requests information that has become available since the previous status review for baiji/Chinese river dolphin/Yangtze River dolphin in February 2012 and Saimaa ringed seal in December 2010. With respect to the baiji, the Commission is not aware of any evidence that might suggest a change to the statement on abundance and population trends in the previous 2012 five-year review which read: “The last photographic supported sighting was in 2002 and the last confirmed stranding was in 2001 (Turvey et al. 2007). In November and December of 2006, a visual and acoustic survey failed to locate a single baiji leading to conclusions that the baiji is likely extinct (Turvey 2008; Turvey et al. 2007) [Citations in original]. A few sightings have been reported since the 2006 range-wide survey, but these reports have not been verified.” With respect to the Saimaa ringed seal, the Commission notes the International Union for Conservation of Nature (IUCN) Red List assessments for all pinnipeds were updated in 2016. -

Status and Biology of Ringed Seals (Phoca Hispida) in Svalbard
Status and biology of ringed seals (Phoca hispida) in Svalbard Christian Lydersen Norwegian Polar Institute, N- 9005 TromsI/J, Norway ABSTRACT The ringed seal is the most abundant mammal in the Svalbard area. Annual pup production in this area is estimated to be 20,000. No systematic harvest records exist, but some few hundred seals are t*en annually, mainly for dog food. The ringed seals in Svalbard are protected from hunting in the period 15 March - 15 April. Peak pupping season is the first week of April. New-born ringed seals weigh an aven~ge of 4.6kg. They are nursed for about 39 days, and weaned at an average body mass of around 22kg. During the period of maternal care pups consume a total of about 54 litres of milk, that is composed of approximately 38% fat and 10% protein. Asymptotic standard lengths and body masses for adult ringed seal males and females are 131.5 and 127.8cm, and 52.6 and 59.9kg, respectively. The maximum values recorded for lengths of males and females in Svalbard are 157cm and 107kg, respectively. There is marked seasonal variation in body mass in both sexes with the highest mass records being recorded in early spring before pupping occurs, and with minimum values in the summer after the breeding and moulting seasons. The observed variation in mass is mainly due to changing blubber thickness of the seals. Ringed seal males attain sexual maturity at the age of 5 - 7 years, while females reach maturity when they are 3-5 years of age. -
