[MARMAM] Interactions between orcas and boats

[Ruth Esteban]

Dear Mamam community,

Since July there have been interactions between orcas and mainly sailing
vessels around the Iberian Peninsula, as far as we know it all started in
southern Spain. According to witnesses, normally the animals go around the
vessel, and ram the hull, making the boat to turn some degrees and even
breaking parts of the rudder. There have been cases also in Portugal, and
now the interactions are concentrated in northern Spain. It is probably the
same group that has been travelling up north, but unfortunately we don't
have pictures/videos which are good enough to confirm it, or even confirm
to which population do they belong to.

It has been all over the news in Spain and Portugal, and now more broadly
(The Guardian:
https://amp.theguardian.com/environment/2020/sep/13/killer-whales-launch-orchestrated-attacks-on-sailing-boats?__twitter_impression=true=09).
We have no clue what could be the motivation of the whales to behave like
this, for this reason it would be really helpful if we could get any input
from other places, where those types of interactions between boats and
killer whales have been happening before. So can you please contact me if
you have any info on something similar?. We would really appreciate it.

Kind Regards,

Ruth

Internship Announcement



The Center for Coastal Studies (CCS), a nonprofit institution dedicated to
the understanding and protection of our coastal environment and marine
ecosystems, is seeking a seasonal Right Whale Ecology Program intern from
January 04 - May 29, 2021. This long-term project focuses on documenting

and their food resource in Cape Cod Bay and adjacent Massachusetts waters.
The intern will assist the habitat research associate in the collection and
processing of zooplankton in the field and lab. Fieldwork responsibilities
include zooplankton collection through tow and pump techniques, marine
observer, and environmental data collector. Lab responsibilities include
zooplankton species identification and counts, plastics analysis, archiving
samples, data entry and maintenance, and maintaining field equipment.

Minimum Requirements

-A college degree, preferably in biological/ environmental sciences

-Good memorization skills and strong attention to details

-Basic computer literacy and experience using Microsoft Office
programs (Excel, Word, PowerPoint). Experience with database entry and
management is preferred

-Experience working on boats, ability to withstand harsh elements,
and not be prone to serious seasickness

-Must be able to live and work well in a team

-Enthusiasm and willingness to learn field and lab-based research
methods

-Strong attention to detail and ability to work well under pressure



Preferred Qualifications:

-Plankton identification

-Microscopy and laboratory experience

-Not prone to seasickness

-A valid US driver’s license



The successful applicant will be required to work a minimum of four full

Atlantic right whale and Cape Cod Bay has been a major critical habitat for
over 50% of the estimated population in recent years. This is an excellent
opportunity for anyone wishing to expand their skills in marine mammal
survey techniques and zooplankton analysis; and will offer the successful
applicant the unique chance to work with one of the world’s most endangered
cetaceans. This internship will afford the successful applicant an
invaluable opportunity to work within a well-established institution, with
highly-qualified scientists, and to gain experience in boat-based research,
zooplankton and environmental collections, plankton identification, plastic
analysis, and data entry and analysis. Details of our work can be found on
our website: http://coastalstudies.org/right-whale-research/

[MARMAM] New publications on fat embolism in stranded cetaceans

[marina arregui]

Dear colleagues,



On behalf of the animal pathology laboratory of the Institute of Animal Health 
and Food Safety of the University of Las Palmas de Gran Canaria, we are pleased 
to announce the following two publications on fat embolism in stranded 
cetaceans:




Arregui, M., Glandon, H. L., Bernaldo de Quirós, Y., Felipe-Jiménez, I., 
Consoli, F., Caballero, M. J., Koopman, H. N. and Fernandez, A. (2020a). Lipids 
of lung and lung fat emboli of the toothed whales (Odontoceti). Sci. Rep. 10, 
14752.


Abstract: Lipids are biomolecules present in all living organisms that, apart 
from their physiological functions, can be involved in different pathologies. 
One of these pathologies is fat embolism, which has been described 
histologically in the lung of cetaceans in association with ship strikes and 
with gas and fat embolic syndrome. to assess pathological lung lipid 
composition, previous knowledge of healthy lung tissue lipid composition is 
essential; however, these studies are extremely scarce in cetaceans. In the 
present study we aimed first, to characterize the lipids ordinarily present in 
the lung tissue of seven cetacean species; and second, to better understand the 
etiopathogenesis of fat embolism by comparing the lipid composition of lungs 
positive for fat emboli, and those negative for emboli in Physeter 
macrocephalus and Ziphius cavirostris (two species in which fat emboli have 
been described). Results showed that lipid content and lipid classes did not 
differ among species or diving profiles. In contrast, fatty acid composition 
was significantly different between species, with C16:0 and C18:1ω9 explaining 
most of the differences. This baseline knowledge of healthy lung tissue lipid 
composition will be extremely useful in future studies assessing lung 
pathologies involving lipids. concerning fat embolism, non-significant 
differences could be established between lipid content, lipid classes, and 
fatty acid composition. However, an unidentified peak was only found in the 
chromatogram for the two struck whales and merits further investigation.

Arregui, M., Fernández, A., Paz-Sánchez, Y., Santana, Á., Sacchini, S., Sierra, 
E., Arbelo, M. and Bernaldo de Quirós, Y. (2020b). Comparison of three 
histological techniques for fat emboli detection in lung cetacean’s tissue. 
Sci. Rep. 10, 8251.



Abstract: Fat embolism is the mechanical blockage of blood vessels by 
circulating fat particles. it is frequently related to traumas involving soft 
tissues and fat-containing bones. Different techniques have been used for 
decades to demonstrate histologically fat emboli, being the extremely toxic 
post-fixation with osmium tetroxide one of the most used techniques in the last 
decades. in the present study, the osmium tetroxide technique was compared 
qualitatively and quantitatively, for the first time, with chromic acid and Oil 
Red O frozen techniques for histological fat emboli detection in the lungs of 
eight sperm whales that died due to ship strikes. This was also the first time 
that chromic acid technique was tested in cetaceans. Results showed that the 
three techniques were valuable for the histological detection of fat embolism 
in cetaceans, even when tissues presented advanced autolysis and had been 
stored in formaldehyde for years. Although quantitative differences could not 
be established, the Oil Red O frozen technique showed the lowest quality for 
fat emboli staining. on the contrary, the chromic acid technique was proven to 
be a good alternative to osmium tetroxide due to its slightly lower toxicity, 
its equivalent or even superior capacity of fat emboli detection, and its 
significantly lower economic cost.
