Tropical teleconnections through the Amundsen Sea Low impact Antarctic toothfish recruitment within the Ross Gyre
Antarctic toothfish (
Dissostichus mawsoni
) in the Ross Sea region are believed to spawn predominantly in the northern parts of the Ross Gyre during the austral winter with fluctuations in their recruitment observed. This Lagrangian modelling study attempts to explain these fluctuations and shows how sea-ice drift impacts the buoyant eggs and the overall recruitment of juveniles reaching the Amundsen shelf break. Interannual variations in the Amundsen Sea Low, linked to tropical sea surface temperatures, cause modulations in the sea-ice drift and subsequent recruitment. When the Amundsen Sea Low is weaker, consistent with El Niño conditions, the northward sea-ice drift reduces, and more eggs remain within the Ross Gyre leading to a larger recruitment success. Conversely, recruitment success reduces during La Niña conditions. The sea-ice drift may explain about 80% of the interannual Antarctic toothfish recruitment variability over the period 1975–2016 and is of particular importance during the first year after spawning. These results enable future interannual changes in Antarctic toothfish recruitment success based on remote observations to be anticipated. Our findings suggest that ongoing climate change strengthening of the Amundsen Sea Low, will likely contribute to a long-term toothfish recruitment decline in the Ross Gyre region.

A comparison of fragmenting lead-based and lead-free bullets for aerial shooting of wild pigs
In response to the health threats posed by toxic lead to humans, scavenging wildlife and the environment, there is currently a focus on transitioning from lead-based to lead-free bullets for shooting of wild animals. We compared efficiency metrics and terminal ballistic performance for lead-based and lead-free (non-lead) bullets for aerial shooting of wild pigs ( Sus scrofa ) in eastern Australia. Ballistic testing revealed that lead-based and lead-free bullets achieved similar performance in precision and muzzle kinetic energy (E 0 ) levels (3337.2 J and 3345.7 J, respectively). An aerial shooting trial was conducted with wild pigs shot with one type of lead-based and one type of lead-free bullets under identical conditions. Observations were made from 859 shooting events ( n = 430 and 429 respectively), with a sub-set of pigs examined via gross post-mortem ( n = 100 and 108 respectively), and a further sub-set examined via radiography ( n = 94 and 101 respectively). The mean number of bullets fired per pig killed did not differ greatly between lead-based and lead-free bullets respectively (4.09 vs 3.91), nor did the mean number of bullet wound tracts in each animal via post-mortem inspection (3.29 vs 2.98). However, radiography revealed a higher average number of fragments per animal (median >300 vs median = 55) and a broader distribution of fragments with lead-based bullets. Our results suggest that lead-based and lead-free bullets are similarly effective for aerial shooting of wild pigs, but that the bullet types behave differently, with lead-based bullets displaying a higher degree of fragmentation. These results suggest that aerial shooting may be a particularly important contributor to scavenging wildlife being exposed to lead and that investigation of lead-free bullets for this use should continue.

The Sonority Controversy
Sonority has a long and contentious history. It has often been invoked by linguists as an explanatory principle underlying various cross-linguistic phonotactic generalizations, especially within the domain of the syllable. However, many phonologists and phoneticians have expressed concerns about the adequacy of formal accounts based on sonority, including even doubts about the very existence of sonority itself.
To date, the topic of sonority has never been the focus of an entire book. Consequently, this is the first complete volume that explores diverging viewpoints about phonological phenomena rooted in sonority taken from numerous languages. All of the contributors are well-known and respected linguists who publish their research in leading academic outlets. Furthermore, each chapter in this collection contains new, cutting-edge results based on the latest trends in the field. Hence, no other extant piece of literature matches this volume in terms of its breadth and coverage of issues, all converging on the common theme of sonority.
Given the wide variety of subtopics in this collection, there is something to appeal to everyone — the list of contributions encompasses areas such as Optimality Theory, acquisition, computational modeling, acoustic phonetics, typology, syllable structure, speech perception, markedness, connectionism, psycholinguistics, and even MRI technology. What ties all of these issues together is a solid and consistent emphasis on sonority as a unified background phenomenon. Furthermore, a continuum of opinions about sonority is represented, ranging from complete acceptance and enthusiasm, on the one hand, to moderate skepticism on the other hand.

Exploring experienced nurses’ views, attitudes and expectations of graduate nurses in the operating theatre
While the new graduate nurse journey has been well documented, little research exists from the perspective of the experienced nurse, particularly in the perioperative environment. Barriers to graduate nurse support need to be understood, as job satisfaction, nurse wellbeing and quality of patient care can be negatively affected.
