Consequences of culturally-driven ecological specialization: Killer whales and beyond
by Hal Whitehead 12 Jun '26

12 Jun '26

The following paper has just been published: Consequences of culturally-driven ecological specialization: Killer whales and beyond. by: Hal Whitehead and John K.B. Ford Journal of Theoretical Biology 456: 279-294 Abstract: Culturally-transmitted ecological specialization occurs in killer whales, as well as other species. We hypothesize that some of the remarkable demographic and ecological attributes of killer whales result from this process. We formalize and model (using agent-based stochastic models parametrized using killer whale life history) the cultural evolution of specialization by social groups, in which a narrowing of niche breadth is spread and maintained in a group through social learning. We compare the demographic and ecological results of cultural specialization to those of a similar model of specialization through natural selection. We found that specialization, through either the cultural or natural selection routes, is adaptive in the short term with specialization often increasing fitness. Generalization, in contrast, is rarely adaptive. The cultural evolution of specialization can lead to increased rates of group extirpation. Specialization has little effect on group size but tends to reduce population size and resource abundance. While the two specialization processes produce similar results, cultural specialization can be very much faster. The results are generally consistent with what we know of the formation and maintenance of specialist ecotypes in killer whales, and have implications for the persistence, nature and ecological effects of these apex predators.

Update to SOCPROG
by Hal Whitehead 01 Jul '24

01 Jul '24

A new and updated version of SOCPROG, SOCPROG2.9 (both compiled and uncompiled downloads) is available at: http://whitelab.biology.dal.ca/SOCPROG/social.htm SOCPROG is a MATLAB-based package of programs for the analysis of animal social structures, movements and populations. The compiled version does not need MATLAB itself. This version is compatible with MATLAB2018b (although it will likely work well on recent and soon-to-be-released versions of MATLAB). It fixes a few bugs and adds functionality compared to previous versions (especially association complexity). Thanks Hal Whitehead, Dalhousie University, Canada

New paper: Far-Field Effects of Impulsive Noise on Coastal Bottlenose Dolphins
by Fernandez, Oihane 15 Sep '23

15 Sep '23

Dear MARMAM colleagues, On behalf of my co-authors I would like to share our recent publication in Frontiers in Marine Science (open access): Fernandez-Betelu O, Graham IM, Brookes KL, Cheney BJ, Barton TR and Thompson PM (2021) Far-Field Effects of Impulsive Noise on Coastal Bottlenose Dolphins. Front. Mar. Sci. 8:664230. doi: 10.3389/fmars.2021.664230 The paper was published as part of the Frontiers research topic "Before-After Control-Impact (BACI) Studies in the Ocean" and can be downloaded freely from: https://www.frontiersin.org/articles/10.3389/fmars.2021.664230/full Abstract Increasing levels of anthropogenic underwater noise have caused concern over their potential impacts on marine life. Offshore renewable energy developments and seismic exploration can produce impulsive noise which is especially hazardous for marine mammals because it can induce auditory damage at shorter distances and behavioral disturbance at longer distances. However, far-field effects of impulsive noise remain poorly understood, causing a high level of uncertainty when predicting the impacts of offshore energy developments on marine mammal populations. Here we used a 10-year dataset on the occurrence of coastal bottlenose dolphins over the period 2009-2019 to investigate far-field effects of impulsive noise from offshore activities undertaken in three different years. Activities included a 2D seismic survey and the pile installation at two offshore wind farms, 20-75 km from coastal waters known to be frequented by dolphins. We collected passive acoustic data in key coastal areas and used a Before-After Control-Impact design to investigate variation in dolphin detections in areas exposed to different levels of impulsive noise from these offshore activities. We compared dolphin detections at two temporal scales, comparing years and days with and without impulsive noise. Passive acoustic data confirmed that dolphins continued to use the impact area throughout each offshore activity period, but also provided evidence of short-term behavioral responses in this area. Unexpectedly, and only at the smallest temporal scale, a consistent increase in dolphin detections was observed at the impact sites during activities generating impulsive noise. We suggest that this increase in dolphin detections could be explained by changes in vocalization behavior. Marine mammal protection policies focus on the near-field effects of impulsive noise; however, our results emphasize the importance of investigating the far-field effects of anthropogenic disturbances to better understand the impacts of human activities on marine mammal populations.

New Online Training Course: An Introduction To Integrating QGIS/GIS And R For Spatial Analysis - 6th to 8th May 2020
by cdmacleod＠gisinecology.com 20 Jan '23

20 Jan '23

We will be running a new online training course called 'An Introduction To Integrating QGIS/GIS and R For Spatial Analysis' between the 6th and 8th of May 2020. It will be held via the Zoom video-conferencing platform. This course is aimed at those who wish to learn how to use and integrate QGIS (the leading freely available GIS software package) and R (the leading freely available data analysis software package) for spatial analysis. It will be taught by Dr. Colin D. MacLeod, the author of 'An Introduction To Integrating QGIS And R for Spatial Analysis [1]' (Pictish Beast Publications) and a renowned expert in using GIS in biological and ecological research. He is also a co-author of the recenntly publised 'An Introduction To Basic Statistics For Biologists Using R [2]', which is a practical guide to carrying out the analysis of biological data in R. The course assumes no prior knowledge of either QGIS/GIS or R, and so is open to complete beginners as well as those how know how to use one of these software packages, and wish to learn how to integrate it with the other. Attendance will be limited to a maximum of 16 people. The course for this three day course will cost GBP 395 per person (with a discounted rate of GBP 300 for students, the unwaged and those working for registered charities). To book a place, or for more information, visit http://gisinecology.com/online-course-an-introduction-to-integrating-qgis-g… or email info(a)GISinEcology.com. GIS and statistical analysis are two of the most fundamental software tools for marine mammalogists wishing to conduct spatial analyses, which is, itself, a cornerstone for the management and conservation of marine mammal species. However, GIS and statistical analyses have their own sets of software packages, and sometimes it can be difficult to know how to integrate the two. This course will provide an introduction to the integration of QGIS (the leading freely available GIS software package) and R (the leading data analysis software packages used by biologists) to create a combined tool set that makes the most of the strengths of each of these individual software packages. It will consist of a series of background sessions on using GIS and R for spatial analysis, mixed in with practical sessions where you will learn how to use QGIS, how to use R, and how to integrate two to complete a spatial analysis project. This last part will include working through an example project, starting with creating a high quality map for publication through creating raster data layers of environmental variables, joining data together based on their spatial relationships and analysing the combined data set using R (including creating summary statistics, conducting linear regressions and conducting generalised additive modelling - GAMs). While it will primarily be based around QGIS, this course is taught using software-independent approach, and it is also open to those who wish to learn how to use ArcGIS to do biological GIS. When you attend this course you will receive a free copy of An Introduction To Integrating QGIS And R for Spatial Analysis [1] (GIS For Biologists Workbooks) as the practical exercises in that course are based on the ones contained in that book. NOTE: If you wish to use ArcGIS software for this course, alternative materials will be provided for the practical sessions. ================================================================================== GIS IN ECOLOGY - Providing Training, Advice And Consultancy On The Use Of GIS In Ecology Web: www.GISinEcology.com Email: info(a)GISinEcology.com Need to ask a question about using GIS?

New paper on spatial variabilities in humpback whale acoustic presence in the Southern Ocean
by Elena Schall 19 Aug '22

19 Aug '22

We are pleased to announce our new paper in Royal Society Open Science on humpback whales in the Southern Ocean: *Large-scale spatial variabilities in the humpback whale acoustic presence in the Atlantic sector of the Southern Ocean* Elena Schall, Karolin Thomisch, Olaf Boebel, Gabriele Gerlach, Stefanie Spiesecke and Ilse Van Opzeeland Southern Hemisphere humpback whales (/Megaptera novaeangliae/) inhabit a wide variety of ecosystems including both low- and high-latitude areas. Understanding the habitat selection of humpback whale populations is key for humpback whale stock management and general ecosystem management. In the Atlantic sector of the Southern Ocean (/ASSO/), the investigation of baleen whale distribution by sighting surveys is temporally restricted to the austral summer. The implementation of autonomous passive acoustic monitoring, in turn, allows the study of vocal baleen whales year-round. This study describes the results of analysing passive acoustic data spanning 12 recording positions throughout the/ASSO/applying a combination of automatic and manual analysis methods to register humpback whale acoustic activity. Humpback whales were present at nine recording positions with higher acoustic activities towards lower latitudes and the eastern and western edges of the/ASSO/. During all months, except December (the month with the fewest recordings), humpback whale acoustic activity was registered in the/ASSO/. The acoustic presence of humpback whales at various locations in the/ASSO/confirms previous observations that part of the population remains in high-latitude waters beyond austral summer, presumably to feed. The spatial and temporal extent of humpback whale presence in the/ASSO/suggests that this area may be used by multiple humpback whale breeding populations as a feeding ground.

New publication

Dear MARMAM community, We are pleased to announce the publication of our new dugong study in Scientific Reports (open access): Derville, S., Cleguer, C. & Garrigue, C. Ecoregional and temporal dynamics of dugong habitat use in a complex coral reef lagoon ecosystem. Sci Rep 12, 552 (2022). [ https://doi.org/10.1038/s41598-021-04412-3 | https://doi.org/10.1038/s41598-021-04412-3 ] [ https://www.nature.com/articles/s41598-021-04412-3 | https://www.nature.com/articles/s41598-021-04412-3 ] Abstract: Mobile marine species display complex and nonstationary habitat use patterns that require understanding to design effective management measures. In this study, the spatio-temporal habitat use dynamics of the vulnerable dugong ( Dugong dugon ) were modelled from 16 satellite-tagged individuals in the coral reef lagoonal ecosystems of New Caledonia, South Pacific. Dugong residence time was calculated along the interpolated tracks (9371 hourly positions) to estimate intensity of use in three contrasting ecoregions, previously identified through hierarchical clustering of lagoon topographic characteristics. Across ecoregions, differences were identified in dugong spatial intensity of use of shallow waters, deeper lagoon waters and the fore-reef shelf outside the barrier reef. Maps of dugong intensity of use were predicted from these ecological relationships and validated with spatial density estimates derived from aerial surveys conducted for population assessment. While high correlation was found between the two datasets, our study extended the spatial patterns of dugong distribution obtained from aerial surveys across the diel cycle, especially in shallow waters preferentially used by dugongs at night/dusk during high tide. This study has important implications for dugong conservation and illustrates the potential benefits of satellite tracking and dynamic habitat use modelling to inform spatial management of elusive and mobile marine mammals.
