Here is the absctrat:

In this short-note, we provided information on an apparent increase in the 
Guadalupe fur seal’s (Arctocephalus townsendi) (GFS) habitat expansion range, 
involving the potential establishment of the first bulls haul-out site located 
in the Midriff Islands Region of the Gulf of California. We highlight the 
relevance of increase research efforts in this area to determine their 
potential colonization, which is relevant due to haul-out site is located in a 
region where important anthropogenic activities (e.g, fishing) are performed, 
representing a potential risk forindividuals welfare and survival during their 
post-breeding migration period along the Gulf of California.

[MARMAM] Marine Mammal Conference Workshops

[Polasek, Lori K (DFG)]

Florida bound friends - We welcome everyone to peruse the list of 15 workshops 
occurring the weekend before the Maine Mammal Conference.  Titles of the 
workshops are below, and more details can be found on the conference website 
(workshops).  As of today, all workshops still have 
space, and we encourage you to attend.


  *   Integrated Conservation Planning for Cetaceans: ICP and this workshop are 
intended to encourage formation of new partnerships, to increase levels of 
trust and understanding among conservation practitioners and stakeholders 
across multiple management contexts, and to expand and enhance the quality of 
the tools available for science-based conservation action.
  *   Shiny tools for management tools: Using R and "shiny" to streamline 
marine mammal conservation: In this workshop we will demonstrate how effective 
conservation tools can be developed by researchers without formal computer 
science training using accessible, open source tools (R and RStudio).
  *   2nd Marine Mammal eDNA Workshop: We will bring together early-career and 
established researchers interested in applying emerging techniques in 
environmental DNA (eDNA) to marine mammal species.
  *   Cachalote Consortium 2019- Behavior, ecology and the structure of sperm 
whale societies - transforming science into stewardship for ocean nomads: The 
Cachalote Consortium was created in 2005 with the goal of bringing together 
researchers from multiple disciplines to promote understanding of global 
patterns of sperm whale biology, ecology and conservation.
  *   Experimental science in wild and captive marine mammals: current and 
future focuses, needs, and collaborations: Panel topics will include 
conservation technology and innovation, bioacoustics and cognition, research 
training, the logistics/specifics of working with facilities, etc.
  *   Individual-based models - predictive models for studying impacts of 
disturbance on marine mammals: The goals of this interactive workshop are to 
identify key processes currently used in marine mammal IBMs and those which 
should be considered in future models, define alternative approaches, and 
outline best practices for going forward.
  *   Marine mammal sensory systems: recent advances and emerging technologies: 
This workshop explores both specific and integrated marine mammal sensory 
systems with a focus on recent advances in this field of research as well as 
emerging technologies that can advance our understanding of (multimodal) 
sensory perception. The workshop will be supported by funding through a 
Scientific Meeting Grant, with funds to reimburse the workshop fee for a 
limited number of participants, preference given to students on a 
first-come-first-served basis.
  *   Tenth International Sirenian Symposium: The Tenth International Sirenian 
Symposium will support and promote Sirenian conservation by providing a venue 
and opportunity for researchers from around the globe to present novel and 
relevant work.
  *   Assessment Approaches to Support Bycatch Management for Marine Mammals: 
The aims of this workshop are to increase the number of marine mammal 
populations for which abundance and bycatch can be estimated and to help 
identify which fisheries are most urgently in need of mitigation.
  *   Exploring Marine Mammal Cognition as a Conservation Tool: This 
multi-disciplinary workshop explores current applications and future expansions 
of cognitive approaches to marine mammal conservation.
  *   Pinniped entanglement prevention and response: sharing best practices to 
improve safety and success: This workshop is intended to bring together 
pinniped researchers, managers, and responders interested in reducing global 
pinniped entanglements and interactions with active fishing gear.
  *   A Research-Based Approach to Collaboration and Communication for 
Conservation: This interactive session uses FourSight, a research-based 
framework that is both universal and instinctive, to explore how people 
approach communication and problem solving.
  *   Acoustic citizen science and tourism vessels - best practices and 
possibilities for the future: The workshop will look at the benefits, barriers, 
and untapped potential for utilizing platforms of opportunity, and citizen 
scientists, for gathering and analyzing acoustic marine mammal and 
environmental data.
  *   US East Coast Offshore Wind Research Opportunities and Coordination: We 
propose to gather developers and scientists together to present ongoing and 
upcoming research, discuss collaborative and funding opportunities, and develop 
a more coordinated effort that minimizes redundancy, improves regional 
communication, and makes researchers aware of current and future funding and 
priority questions identified by agencies and stakeholder processes.
  *   Win More Battles for Marine Mammals!!! Science Communication for REAL 
Impact: Our goal is to have participants leave 1) understanding why they must

[MARMAM] SMM Editor’s Select Series Feeding tactics of resident Brydes whales

[Student Members-at-Large Society for Marine Mammalogy]

Greetings Marmam,

Join us on Friday May 20th, 11 am NZST (Thursday May 19th, 4 pm PDT / 7 pm
EDT / 11 pm GMT) for the next SMM Seminar Editors' Select Series: Feeding
tactics of resident Bryde's whales in New Zealand with Dr. Sahar Izadi of
the University of Auckland.

Free to attend. Registration required. Presented online on Zoom.

Register here:
https://us06web.zoom.us/webinar/register/WN_90MvXhciTZ61bj-3rNwA-g

Space on Zoom is limited to the first 500 attendees.
The talk will also be streamed live on the SMM Facebook page.

The SMM Seminar Editors' Select Series highlights the latest and most
exciting marine mammal science published in the Marine Mammal Science
Journal. This is your chance to engage with marine mammal scientists, learn
and ask questions from anywhere in the world.
All are welcome.

About this talk:
Baleen whales are the largest mammals on earth, but many questions about
their behaviour remain unanswered as they are submerged in the pelagic
environment. Among baleen whales, Bryde’s whales are one of the least
known. They are a non-migrating species of baleen whale with a wide
distribution. There is a small (∼ 135) year-round population of Bryde’s
whales in the Hauraki Gulf, New Zealand. We investigated their foraging
behaviour using data collected by an archival tag (DTAG2), boat-based
surveys, and drones. Our investigation not only revealed some interesting
aspects of their foraging behaviour, but also helped us to understand other
aspects of their lives such as rest.

About the presenter:
After receiving a masters in Marine Mammal Science from the University of
St Andrews, Sahar moved to New Zealand to do a PhD at the University of
Auckland. She completed her PhD on behavioural ecology of Bryde’s whales
and graduated in 2019. Since then, she has been doing something completely
different from marine mammal science; she is a co-founder at a tech
start-up in New Zealand. But, she thinks she hasn’t distanced herself from
science, still working on the papers from her PhD and believes she will get
back to marine science world full time in the future.

Best regards,

[MARMAM] New Paper: Calf-directed aggression as an infanticide attempt in Pacific white-sided dolphins (Leanne Rosser)

[Leanne Rosser]

Hello everyone,

On behalf of our team here in Japan at Mutsu Bay Dolphin Research, I would
like to announce the publication of our new paper:

'Calf-directed aggression as a possible infanticide attempt in Pacific
white-sided dolphins (Lagenorhynchus obliquidens).'

Our latest work has been published in the current issue of Aquatic Mammals
and can be found here:

https://doi.org/10.1578/AM.48.3.2022.273

Abstract:
We report the first case of conspecific calf-directed aggression in Pacific
white-sided dolphins (Lagenorhynchus obliquidens) as a possible infanticide
attempt in Mutsu Bay, Japan. Our observation of a 75-minute-long persistent
attack on a neonate was performed by 10 attackers (4 adult males, 1
possible male, and 5 of unknown sex) and left the neonate with visible
injuries. Only one individual was recorded for the entirety of the event
and was regarded as the suspected mother, displaying protective behaviours
towards the neonate as well as being the target of coercive guarding and
sexual behaviours, such as mounting, by the attackers. The observation
featured a distinct group composition change in which after 50 minutes the
attack was taken over by a new group of attackers. There was a brief
overlap between the groups in which some dolphins from the first group
surfaced with the second. Excluding the mother and calf, only two
individuals that were observed towards the end of the first group attack,
remained with the second group until the end of the observation. The first
group of attackers did not make further aggressive attempts on the neonate
or presumed mother, and no conflict between the two groups was witnessed.
The second group continued the attack with significantly increased
aggression and a greater array of behavioural types than the first, often
dividing into two approximately 5-10 m distanced subgroups, one that herded
the suspected mother and another that focused on attacking the neonate. Our
study analysed the frequency and variety of behavioural types used in the
attack and compared them between individuals and the two separate attack
groups. The group change we observed is absent from the literature on
conspecific calf-directed attacks in other cetacean species and, if this is
an infanticide attempt, provides new insight into the social structure of
Pacific white-sided dolphins.
