Abstract: The interpretation and use of bio ersity offsets in planning and development is a contentious issue because they rarely encompass each of the environmental, social and economic aspects of sustainable development. While currently agreed best practice for bio ersity offsets includes consideration of scope, scale, location, timing and duration, and monitoring, current literature on these components does not consider all aspects of sustainable development. Furthermore, much of the current agreed best practice focusses on the design of bio ersity offsets, without consideration of ongoing management or end-of-life. This manuscript reviews current best practice for bio ersity offsets, giving consideration to the environmental, social and economic aspects of sustainable development. In particular, we report that consideration of cost and risk is key and the use of planning frameworks, bonds and advanced offsets could mitigate these risks and allow for long-term success. Following this approach, a holistic model for design, implementation and ongoing management of direct bio ersity offsets that balances all aspects of sustainable development is presented.

Abstract: Large sea-going passenger vessels can pose a high biosecurity risk. The risk posed by marine species is well documented, but rarely the risk posed by terrestrial arthropods. We conducted the longest running, most extensive monitoring program of terrestrial arthropods undertaken on board a passenger vessel. Surveillance was conducted over a 19-month period on a large passenger (cruise) vessel that originated in the Baltic Sea (Estonia). The vessel was used as an accommodation facility to house workers at Barrow Island (Australia) for 15 months, during which 73,061 terrestrial arthropods (222 species - four non-indigenous (NIS) to Australia) were collected and identified on board. Detection of Tribolium destructor Uytt., a high-risk NIS to Australia, triggered an eradication effort on the vessel. This effort totalled more than 13,700 human hours and included strict biosecurity protocols to ensure that this and other non-indigenous species (NIS) were not spread from the vessel to Barrow Island or mainland Australia. Our data demonstrate that despite the difficulties of biosecurity on large vessels, stringent protocols can stop NIS spreading from vessels, even where vessel-wide eradication is not possible. We highlight the difficulties associated with detecting and eradicating NIS on large vessels and provide the first detailed list of species that inhabit a vessel of this kind.

Abstract: The use of shipping containers for cargo transportation has the potential to transport insect pests from infested to non-infested areas. Therefore, fumigation is required as an appropriate biosecurity measure to exterminate these pests. In-transit fumigation trials were conducted in two 20 ft shipping containers during a two-day journey in both September and December 2017. Ethyl formate (90 g m

Abstract: This book covers the proceedings of a major 2006 symposium on macropods that brought together the many recent advances in the biology of this erse group of marsupials, including research on some of the much neglected macropods such as the antilopine wallaroo, the sw wallaby and tree-kangaroos. More than 80 authors have contributed 32 chapters, which are grouped into four themes: genetics, reproduction and development morphology and physiology ecology and management. The book examines such topics as embryonic development, immune function, molar progression and mesial drift, locomotory energetics, non-shivering thermogenesis, mycophagy, habitat preferences, population dynamics, juvenile mortality in drought, harvesting, overabundant species, road-kills, fertility control, threatened species, cross-fostering, translocation and reintroduction. It also highlights the application of new techniques, from genomics to GIS. Macropods is an important reference for academics and students, researchers in molecular and ecological sciences, wildlife and park managers, and naturalists.

Abstract: Cyantraniliprole is the first diamide insecticide to have cross‐spectrum activity against a broad range of insect orders. The insecticide, like other diamides, selectively acts on ryanodine receptor, destroys Ca 2+ homeostasis, and ultimately causes insect death. Although expression regulations of genes associated with calcium signaling pathways are known to be involved in the response to diamides, little is known regarding the function of calmodulin (CaM), a typical Ca 2+ sensor central in regulating Ca 2+ homeostasis, in the stress response of insects to the insecticide. In this study, we cloned and identified the full‐length complementary DNA of CaM in the whitefly, Bemisia tabaci (Gennadius), named BtCaM . Quantitative real‐time reverse transcription polymerase chain reaction‐based analyses showed that the messenger RNA level of BtCaM was rapidly induced from 1.51‐ to 2.43‐fold by cyantraniliprole during 24 h. Knockdown of BtCaM by RNA interference increased the toxicity of cyantraniliprole in whiteflies by 42.85%. In contrast, BtCaM expression in Sf9 cells significantly increased the cells’ tolerance to cyantraniliprole as much as 2.91‐fold. In addition, the expression of BtCaM in Sf9 cells suppressed the rapid increase of intracellular Ca 2+ after exposure to cyantraniliprole, and the maximum litude in the Sf9‐BtCaM cells was only 34.9% of that in control cells ( Sf9‐PIZ/V5 ). These results demonstrate that overexpression of BtCaM is involved in the stress response of B. tabaci to cyantraniliprole through regulation of Ca 2+ concentration. As CaM is one of the most evolutionarily conserved Ca 2+ sensors in insects, outcomes of this study may provide the first details of a universal insect response to diamide insecticides.

Abstract: Mangrove communities in the tropical north of Australia are some of the most species rich in the world, yet surprisingly little is known of their reproductive and vegetative phenology. This study investigated the phenology of four mangrove species: Avicennia marina (Forsk.) Vierh., Ceriops australis (C.T.White) Ballment, T.J.Sm & Stoddart, Rhizophora stylosa Griff. and Sonneratia alba J.Smith, in Darwin Harbour over 24 months. Investigations included documenting the flowering and fruiting phenology, periods of leaf flush and leaf longevity. Flowering in these mangroves generally occurred during the dry season (June–October), with the exception of R. stylosa in which flowering occurred in the middle of the wet (December–February). Fruits and propagules were released in the dry and ‘build up’ periods (August–November), with the exception of A. marina, which released propagules in the middle of the wet season. Fruit and/or propagule maturation took less than 2 months in A. marina and S. alba, whereas in C. australis and R. stylosa maturation took 12 and 11 months, respectively. Timing of new leaf production generally coincided with the wet season, after the flowering and fruiting periods of each of the four species. Periods of leaf flush and leaf fall were often closely linked, and species with longer-lived leaves produced fewer leaves at each period of leaf flush. Maximum leaf longevity varied considerably among mangroves, ranging from 8 months in the lower canopy of S. alba to more than 24 months in C. australis. There was also large variability in leaf longevity among different regions of the canopy, with shade leaves generally living longer than sun leaves, and leaves in the upper canopy (3–7 m) longer than those in the lower regions (0–3 m).

Abstract: To date seagrass monitoring has involved the removal of seagrass from its environment. In fragile or highly disturbed systems, monitoring using destructive techniques may interfere with the environment or add to the burden of disturbance. Video photography is a form of non-destructive monitoring that does not require the removal of seagrass or interference with the environment and has the potential to be a valuable tool in monitoring seagrass systems. This study investigated the efficacy of video photography as a tool for detecting change in seagrass cover, using the temperate Australian species Amphibolis antarctica (Labill.) Sonder ex Aschers. Using visual and random point estimates of seagrass cover from video footage, it was possible to determine the minimum s le size (number of random video frames) needed to detect change in seagrass cover, the minimum detectable change in cover and the probability of the monitoring design committing a Type II error. Video footage was examined at three scales: transects (m apart), sites (km apart) and regions (tens of km apart). Using visual and random point estimation techniques, a minimum s le size of ten quadrats per transect was required to detect change in uniform and variable seagrass cover. With ten quadrats it was possible to identify a minimum detectable change in cover of 15% for uniform and 30% for variable seagrass cover. Power analysis was used to determine the probability of committing a Type II error from the data. Region level data had low power, corresponding to a high risk of committing a Type II error. Site and transect level data had high power corresponding to a low risk of committing a Type II error. Based on this study's data, managers using video to monitor for change in seagrass cover are advised to use data from the smaller scale, for ex le, site and transect level data. By using data from the smaller scale, managers will have a low risk of incorrectly concluding there has not been a disturbance when one has actually occurred.
