Subject: CAMMS update

Current Advances in Marine Mammal Science (CAMMS) was developed to help keep
researchers informed of current marine mammal publications.

The current update covers the dates of 27 Sept and 07 Oct. and users can now
search for references by the addition date.  Instructions are available at
<http://camms.tamug.tamu.edu/>http://camms.tamug.tamu.edu.

Attached are a few of the 132 references added to CAMMS.

beluga whales (Delphinapterus leucas). Applied Organometallic Chemistry
12(8-9):651-656.
Fifty-two beluga whale samples (Six liver samples, and 46 blubber samples
including ones from different depths of the fat layer) from the St Lawrence
River, Canada, were analyzed for butyltin compounds (mono-, di-, and
tri-butyltin) with a view to investigating the occurrence and contamination of
butyltin in these;animals, A special procedure was also developed for the
determination of butyltin compounds in blubber samples with high lipid content
(up to 95%), Total-butyltin concentrations in liver samples were found to be
much higher than those in the blubber samples. The concentrations of butyltin
compounds in blubber samples were observed to Be related to their lipid
content. Concentration levels of butyltin species in beluga whale were
compared
with those in other marine vertebrates in other parts of the world. The
presence of butyltin compounds in liver and blubber samples suggests the
accumulation of these toxicants by beluga whale.


Venegas,C.C. 1997. Estimation of population density by aerial line
transects of
Commerson's dolphin Cephalorhynchus commersonii in the Strait of Magellan,
Chile. Anales del Instituto de la Patagonia Serie Ciencias Naturales 24:41-48.
Results of an aerial sampling of Commerson's dolphin Cephalorhynchus
commersonii carried on during early summer (1989-1990) at the eastern
sector of
the Strait of Magellan are reported. The methodology employed was the
estimation of densities by mean of line transects. During two days 79
transects
were flown, corresponding to 1,320 km. Because of previous studies indicating
the existence of significant differences between the densities of the narrows
and the wide parts, the sampling between both sectors was stratified. The
total
estimated numbers within the study area was of 718 +- 196 individuals. These
outputs seems promising for the current state of conservation of the species,
as compared with those gotten previously by the author; however, one must bear
in mind that those previous results were obtained during autumn, period of
possible post summer migrations. On the other hand, when comparing them with
those gotten during summer by other authors, the figures of the present study
do not even reach up to one fourth of the estimated in that season. Due to the
high variability of these figures, it is suggested a higher frequency of
monitoring studies on this population of dolphins.

metabolites of polychlorinated biphenyls (PCBs) in cetaceans from the Irish
and
the Aegean Seas. Archives of Environmental Contamination and Toxicology
35(1):121-128.
The levels of PCBs and PCB methyl sulphone metabolites were determined in the
blubber of six species of cetaceans that originated from the Irish Sea and the
Aegean Sea (Mediterranean). Burdens ranging from 2.80 to 27.80 mu g g(-1)
(lipid weight) total PCBs and 0.03 to 0.58 mu g g(-1) (lipid weight) total
methyl sulphones were recorded. The highest cetacean methyl sulphone burden
(0.58 mu g, g(-1)) was in an Irish Sea harbor porpoise (Phocoena phocoena).
Methyl sulphone isomer formation capacity, as determined by PCB:MSF ratios,
varied considerably between species as follows: harbour porpoise (1:10) >
pilot
whale (Globicephalus melas), white-sided dolphin (Lagenorhyncus acutus)
(1:50) >
common dolphin (Delphinus delphis), Risso's dolphin (Grampus griseus), and
striped dolphin (Stenella coerueoalba), (1:100), and was related to
interspecific variation in PCB methyl sulphone formation capacity.

cetaceans from Monte Voltraio (Tuscany, Italy). Biostratigraphical,
paleoecological and paleoclimatic observations. Rivista Italiana di
Paleontologia e Stratigrafia 104(1):123-129.
The historic collection of fossil odontocetes (Cetacea) from Monte Voltraio,
near Volterra (Tuscany, Italy) has been examined and lithostratigraphical and
biostratigraphical investigations on the find locality have been carried out.
The Monte Voltraio outcrop is referred to the Middle Pliocene, in
particular to
Globorotalia aemiliana and Discoaster tamalis zones. The odontocete remains
are
assigned to the families Kogiidae (Kogia pusilla) and Delphinidae
(Globicephala?
etruriae and two indeterminate specimens which might belong to
Hemisyntrachelus
and Stenella giulii). The Middle Pliocene cetacean fauna from the
Mediterranean
basin (Monte Voltraio and Rio Stramonte associations) includes extinct taxa or
extant taxa no longer represented in this basin. The disappearance of these
taxa may be linked with the Pliocene and/or Quaternary climatic deteriorations
(e.g. the climatic crisis at about 2.6-2.4 MA).
