Dear MARMAM friends and colleagues,
my coauthors and I are pleased to announce the publication of the following papers. They both offer reflections on the phenomenon of swim-with wild dolphins and its management, but approach the topic from two, quite different, perspectives.
Fumagalli M., Cesario A., Costa M., Notarbartolo di Sciara G., Harraway J. and Slooten E. (2019). Population ecology and the management of whalewatching operations on a data-deficient dolphin population.
Abstract: 1) Whale watching is a popular commercial activity, producing
socio‐ecological benefits but also potential long‐term effects on the
targeted cetacean population. This industry is currently developing in
data‐deficient contexts in a largely unregulated fashion. Management
schemes should adopt precaution and be informed by the relevant
literature, but would be more effective if the assessment of the target
population vulnerability, biological impacts, and management
implications was drawn from site‐specific data. 2) This paper focuses on a reef‐associated,
data‐deficient population of spinner dolphins in the Egyptian Red Sea.
In Satayah Reef, new information on population size and dynamic
parameters were documented using visual observation and
photo‐identification‐based capture–recapture methods
(Cormack–Jolly–Seber time‐since‐marking model). 3) Dolphins occurred on 98% of the survey days. Average school size was 66 individuals (±42.1 SE),
with most groups including calves. The population was equally divided
into recurrent and transient individuals. An “emigration + mortality”
model best described residence at the site. Five recurrent males (5% of
the Satayah population) provided connectivity between this and the
geographically close population of Samadai Reef. 4) Average annual survival probability was 0.83 (±0.06 SE) in the year following first capture and 0.99 (±0.06 SE) for recurrent individuals. Mean yearly population sizes ranged 143–207 individuals. 5) The study had the power to detect a 30% decline in
the population, but not the rate of change in abundance estimated from
the data (r = 0.018 ± 0.04), which would have required a 3‐ to 5‐times longer study. Synthesis and application: These findings
advance the assessment of the Satayah population's intrinsic
vulnerability and have three major management applications: (a) the
delineation of management units; (b) the identification of key
indicators for future impact monitoring and assessment; and (c)
realistic estimates of the statistical power for trend detection. Based
on our results, we recommend supporting future research, devising
site‐specific time–area closure plans, and integrating them in a
regional scheme. Approaches employed in this case study can inform the
management of whale watching industries targeting other data‐deficient
populations
Bertella G., Fumagalli M. and Williams-Grey V. (2019). Wildlife tourism through the co-creation lens.
Abstract: This study reflects on the conceptualisation of wild animals as
co-creators. Its purpose is to encourage reflection about the role of
animals in wildlife tourism. Therefore, to this end – and in the belief
that diversity and creativity are important elements in critical
thinking – the study was developed by a research team with diverse
professional backgrounds. It adopts a fictional methodological approach,
employing a fictive dialogue between a tourist joining a
swim-with-dolphins tour and a dolphin and draws upon recent scholarly
contributions on animals from the perspective of various disciplines,
including philosophy, biology and tourism, The study’s most important
contribution comes in the form of a discussion of the co-creation
concept from a critical perspective, based on innovative and
explicitly-described ontological, epistemological and methodological
considerations
