“…A common issue for biosecurity managers is a dearth of knowledge concerning potential invading species' life-histories that might inform management opportunities, probable impacts to value attributes, and mechanisms of dispersal (e.g., Hewitt et al 2004;Azmi et al 2015). One lesson from invasion ecology readily applied to A. planci is the understanding of critical stages in life-history to inform cost-effective management actions and determine outbreak triggers (Pratchett et al 2014).…”

“…The spatial component targets potential sources and strategically identified sinks. An epidemiological approach that utilises network theory (e.g., Kiss et al 2006;Youssef et al 2011) to create hub and spoke models (e.g., Azmi et al 2015) could be useful for identifying the starting point of an outbreak and the subsequent spread both temporally and spatially. The surveillance regime would need to be sensitive enough to detect the pests at an appropriate scale while also at low enough densities, but requires understanding of trade-offs between effort and benefit (e.g., Davidson et al 2015).…”

“…Given A. planci are native to the Great Barrier Reef, epidemiology could be used to understand the boom and bust cycle of the species and potential origins or initiation points. Coupled with hub and spoke models (e.g., Azmi et al 2015) that focus on how the species will spread, will provide and idea of where rapid response efforts need to be deployed.…”

Coral reef systems are in global decline. In Australia, much of this decline has been attributable to cyclic outbreaks (every ~17 years) of the coral-feeding crown-of-thorns seastar. While a native species, when in large enough densities the seastar acts like an invasive pest. Since 2012 the Australian government has invested significantly in a targeted control program using lethal injection. While this program is effective for individual reefs, it is not a complete strategy for the entire Great Barrier Reef (~2,500 reefs). In order to find a longer-term solution to the problem, in 2015, the lead author travelled to New Zealand, the United States, and Canada under a Churchill Fellowship to understand successful aquatic integrated pest management strategies and their potential application to the Great Barrier Reef. Meetings and workshops were convened with experts who specialise in risk assessment, categorisation, and management of aquatic invasive species. The experts comprised academics, applied scientists, policy makers, and a not for profit community based invasive species council. Bioinvasion management and prioritisation of management effort using risk-based frameworks were reviewed for application to the crown-of-thorns seastar. This viewpoint is novel in its approach of applying invasive species tools and perspectives to a non-invasive, native marine pest. Early detection and rapid response is key to preventing the transition of the seastar from natural densities to outbreak densities. However given the seastar is a native species already established, when in outbreak mode a multifaceted post-border management approach is essential. Private support funding models, that bridge conservation and tourism/philanthropy have proved successful in New Zealand to supplement government funded marine reserve management -this is an approach which should be explored by Australia to help manage the seastar. Dedicated support and commitment is needed to break the issue-attention cycle. On the Great Barrier Reef, a dedicated biosecurity approach should be used to maintain the seastar at natural densities, increase the time between outbreaks, protect coral cover and increase resilience of the system.

“…The Sunda Strait is an alternative route of shipping when the traffic flow in the Malacca Strait is inhibited [5], [6]. Therefore, the Sunda Strait is the route commonly used for international shipping lanes [7], [8] as well as the crossing path from Java Island to Sumatra Island [9]. The depth in the Sunda Strait waters ranges from 0.5 m to 1,885 m [10]- [12].…”

The characteristic of tide is different for each region. Co-tidal charts are one of the media to present an information about the character of tidal. There are two types of co-tidal chart, such as co-phase chart and co-range chart. Co-phase chart will show the distribution of tides, meanwhile the co-range chart will show the propagation direction of tides. Sunda Strait was chosen to analyze the tidal propagation pattern. The amount of the tidal station which were observed are 33 stations across Sunda Strait. This research used four harmonic constituents of tide, such as M2, S2, K1 O1 and the chart of Sunda Strait to establish cotidal charts. The harmonic constituent of tide was analyzed by Admiralty Method. These data were obtained from Hydrography and Oceanography Center, Indonesian Navy (PUSHIDROSAL). The result of this research shows the tidal propagation direction of semidiurnal harmonic constituents of tide (M2, S2) that flows in south area of Sunda Strait (comes from Indian Ocean through the western part of Sumatra island). Meanwhile, in north area of Sunda Strait, the tidal propagation that comes from Indian Ocean flows through Karimata Strait. The direction of tidal propagation of diurnal harmonic constituents of tide (K1, SO1) that flows in Sunda Strait comes from Pacific Ocean through Karimata Strait. However, the tidal type in Sunda Strait is dominated by mixed tide prevalling semidiurnal and the highest amount of Z0 is 100 cm, meanwhile the lowest value of Z0 in Sunda Strait is 40 cm.

Prioritising surveillance for alien organisms transported as stowaways on ships travelling to South Africa

The global shipping network facilitates the transportation and introduction of marine and terrestrial organisms to regions where they are not native, and some of these organisms become invasive. South Africa was used as a case study to evaluate the potential for shipping to contribute to the introduction and establishment of marine and terrestrial alien species (i.e. establishment debt) and to assess how this varies across shipping routes and seasons. As a proxy for the number of species introduced (i.e. ‘colonisation pressure’) shipping movement data were used to determine, for each season, the number of ships that visited South African ports from foreign ports and the number of days travelled between ports. Seasonal marine and terrestrial environmental similarity between South African and foreign ports was then used to estimate the likelihood that introduced species would establish. These data were used to determine the seasonal relative contribution of shipping routes to South Africa’s marine and terrestrial establishment debt. Additionally, distribution data were used to identify marine and terrestrial species that are known to be invasive elsewhere and which might be introduced to each South African port through shipping routes that have a high relative contribution to establishment debt. Shipping routes from Asian ports, especially Singapore, have a particularly high relative contribution to South Africa’s establishment debt, while among South African ports, Durban has the highest risk of being invaded. There was seasonal variation in the shipping routes that have a high relative contribution to the establishment debt of the South African ports. The presented method provides a simple way to prioritise surveillance effort and our results indicate that, for South Africa, port-specific prevention strategies should be developed, a large portion of the available resources should be allocated to Durban, and seasonal variations and their consequences for prevention strategies should be explored further.
