Abstract:

Death or injury to whales from vessel strike is one of the primary threats to 
whale populations worldwide. However, quantifying the rate of occurrence of 
these collisions is difficult because many incidents are not detected 
(particularly from large vessels) and therefore go unreported. Furthermore, 
varying reporting biases occur related to species identification, spatial 
coverage of reports and type of vessels involved. The International Whaling 
Commission (IWC) has compiled a database of the worldwide occurrence of vessel 
strikes to cetaceans, within which Australia constitutes ∼7% (35 reports) of 
the reported worldwide (∼471 reports) vessel strike records involving large 
whales. Worldwide records consist largely of modern reports within the last two 
decades and historical evaluation of ship strike reports has mainly focused on 
the Northern Hemisphere. To address this we conducted a search of historical 
national and international print media archive databases to discover reports of 
vessel strikes globally, although with a focus on Australian waters. A 
significant number of previously unrecorded reports of vessel strikes were 
found for both Australia (76) and worldwide (140), resulting in a revised 
estimate of ∼15% of global vessel strikes occurring in Australian waters. This 
detailed collation and analysis of vessel strike data in an Australian context 
has contributed to our knowledge of the worldwide occurrence of vessel strikes 
and challenges the notion that vessel strikes were historically rare in 
Australia relative to the rest of the world. The work highlights the need to 
examine historical records to provide context around current anthropogenic 
threats to marine fauna and demonstrates the importance of formalized reporting 
structures for effective collation of vessel strike reports. This paper 
examines the issues and biases in analysis of vessel strike data in general 
that would apply to any jurisdiction. Using the Australian data as an example 
we look at what information can be inferred from historical data and the 
dangers of inference without consideration of the reporting biases.

Joshua Smith

Quantifying ship strike risk to breeding whales in a multiple-use Marine Park: 
The Great Barrier Reef

ABSTRACT: Spatial risk assessments are an effective management tool used in 
multiple-use marine parks to balance the needs for conservation of natural 
properties and to provide for varying socio-economic demands for development. 
The multiple-use Great Barrier Reef Marine Park (GBRMP) has recently 
experienced substantial increases in current and proposed port expansions and 
subsequent shipping. Globally, large whale populations are recovering from 
commercial whaling and ship strike is a significant threat to some populations 
and a potential welfare issue for others. Within the GBRMP, there is spatial 
conflict between the main breeding ground of the east Australian humpback whale 
population and the main inner shipping route that services several large 
natural resource export ports. The east coast humpback whale population is one 
of the largest humpback whale populations globally, exponentially increasing 
(11% per annum) close to the maximum potential rate and estimated to reach 
pre-exploitation population
numbers in the next 4-5 years. We quantify the relative risk of ship strike to 
calving and mating humpback whales, with areas of highest relative risk 
coinciding with areas offshore of two major natural resource export ports. We 
found females with a dependent calf had a higher risk of ship strike compared 
to groups without a calf when standardized for group size and their inshore 
movement and coastal dependence later in the breeding season increases their 
overlap with shipping, although their lower relative abundance decreases risk. 
The formalization of a two-way shipping route has provided little change to 
risk and projected risk estimates indicate a three- to five-fold increase in 
risk
to humpback whales from ship strike over the next 10 years. Currently, the 
whale Protection Area in the GBRMP does not cover the main mating and calving 
areas, whereas provisions within the legislation for establishment of a Special 
Management Area during the peak breeding season in high-risk areas could occur. 
A common
mitigation strategy of re-routing shipping lanes to reduce risk is not a viable 
option for the GBRMP due to physical spatial limitations imposed by the reef, 
whereas speed restrictions could be the most feasible based on current ship 
speeds.

Cheers
Josh

[MARMAM] New publication

2020-08-12 Thread Joshua Smith
My co-authors and I are pleased to announce the publication of our open access 
paper in Ecological Applications

Validation of presence‐only models for conservation planning and the 
application to whales in a multiple‐use marine park
Joshua N. Smith, Natalie Kelly and Ian W. Renner

Identification of species’ Biologically Important Areas (BIAs) is fundamental 
to conservation planning and species distribution models (SDMs) are a powerful 
tool commonly used to do this. Presence‐only data are increasingly being used 
to develop SDM’s to aid the conservation decision‐making process. The 
application of presence‐only SDM’s for marine species’ is particularly 
attractive due to often logistical and economic costs of obtaining systematic 
species’ distribution data. However, robust model validation is important for 
conservation management applications that require accurate and reliable 
species’ occurrence data (e.g. spatially explicit risk assessments). This is 
commonly done using a random subset of the data and less commonly with fully 
independent test data. Here, we apply a spatial block cross‐validation (CV) 
approach to validate a MaxEnt presence‐only model using independent 
presence/absence survey data for a highly mobile, marine species (humpback 
whale, Megaptera novaengliae) in the Great Barrier Reef (GBR). A MaxEnt model 
was developed using opportunistic whale sightings (2003 - 2007) and then used 
to identify areas differing in habitat suitability (low, medium, high) to 
conduct a systematic, line‐transect aerial survey (2012) and derive a density 
surface model. A spatial block CV buffering strategy was used to validate the 
MaxEnt model, using the opportunistic sightings as training data and 
independent aerial survey sightings data as test data. Moderate performance 
measures indicate MaxEnt was reliable in identifying the distribution patterns 
of a mobile whale species on their breeding ground, indicated by areas of high 
density aligned to areas of high habitat suitability. Furthermore, we 
demonstrate that MaxEnt models can be useful and cost‐effective for designing a 
sampling scheme to undertake systematic surveys that significantly reduces 
sampling effort. In this study, higher quality information on whale 
reproductive class (calf versus non‐calf groups) was obtained that the 
presence‐only data lacked, while sampling only 18% of the GBR World Heritage 
Area. The validation approach using fully independent data provides greater 
confidence in the MaxEnt model, which indicates significant overlap with the 
main breeding ground of humpback whales and the inner shipping route. This is 
important when evaluating presence‐only models within certain conservation 
management applications, such as spatial risk assessments.

[MARMAM] PhD opportunity - Australian southern right whales

2023-09-02 Thread Joshua Smith
Dear colleagues,

We wanted to let you know of an exciting PhD opportunity to study the 
conservation status and population dynamics of Australia's endangered southern 
right whales through the Institute for Marine and Antarctic Studies (IMAS) of 
the University of Tasmania in Hobart. IMAS has a strong reputation in Fisheries 
and Aquaculture, Ecology and Biodiversity, and Oceans and Cryosphere with 
cross-disciplinary themes of Climate Change. Critical to this project will be 
an understanding of how climate change has and likely will impact upon the 
recovery of this species.

Project title: Population Dynamics of Right 
Whales<https://www.utas.edu.au/research/degrees/available-projects/projects/marine-and-antarctic/population-dynamics-of-right-whales?fbclid=IwAR3cNET0TSoy9PuHwTrEa-bhaN-lHtbjnsxtbXb07WyJQ74dqb7Kxleqi_A>

This PhD project will utilise a long-term program (over four decades) of annual 
aerial survey data on Australia's southern right whale population that was 
initiated and maintained by the late John Bannister since the mid 1970's. The 
successful candidate will contribute to the curation, analysis, and publication 
of the southern right whale aerial survey dataset and strongly collaborate with 
the Australian and international southern right whale research community on 
ongoing research into Australian southern right whale population dynamics and 
potential impacts from climate change on southern right whales.

The candidate will:

-  conduct time series analysis of the aerial survey count data to 
determine long-term population trends and associated variability;

-  assess methods to estimate population size and estimate change in 
the spatial distribution of sightings over the survey period;

-  determine whether oceanographic conditions on Southern Ocean summer 
feeding grounds correlate with annual calving rates by developing past climate 
histories in likely foraging areas; and,

-  assess the utility of satellite imagery to complement or replace 
annual aerial surveys for annual censuses of right whales in southern Australia.

Funding
Applicants will be considered for a Research Training Program (RTP) scholarship 
or Tasmania Graduate Research Scholarship (TGRS) which, if successful, provides:

-  a living allowance stipend of $31,500 per annum (2023 rate, indexed
