Life cycle assessment (LCA) of shrimp aquaculture is hampered by widely divergent results, with reported impacts varying by more than fiftyfold across key categories. This systematic review of 16 peer‐reviewed LCAs provides quantitative evidence that much of this divergence is driven by analytical choices rather than on‐farm performance: In this case study covering 37 farming cycles, methodological differences in shrimp LCAs i...

Purpose The aim of this study was to confirm the impact of heat acclimation on aerobic performance in hot conditions and elucidate the transfer of heat adaptations to cool and hypoxic environments. Methods Ten males (VO 2peak : 4.50 ± 0.50 L/min) completed two three-week interventions consisting of heat acclimation (HA: 36°C and 59% RH) and temperate training (TEMP: 18°C and 60% RH) in a counter-balanced crossover design. Trai...

Globally, collapse of ecosystems—potentially irreversible change to ecosystem structure, composition and function—imperils biodiversity, human health and well‐being. We examine the current state and recent trajectories of 19 ecosystems, spanning 58° of latitude across 7.7 M km 2 , from Australia's coral reefs to terrestrial Antarctica. Pressures from global climate change and regional human impacts, occurring as chronic ‘press...

Artificial lights at night cause high mortality of seabirds, one of the most endangered groups of birds globally. Fledglings of burrow‐nesting seabirds, and to a lesser extent adults, are attracted to and then grounded (i.e., forced to land) by lights when they fly at night. We reviewed the current state of knowledge of seabird attraction to light to identify information gaps and propose measures to address the problem. Althou...

In this study, a total of 212 eggs were visually identified as snapper Chrysophrys auratus . Real‐time PCR confirmed visual identification in 69% of cases but corroboration varied widely among plankton samples. The use of molecular tools to support visual identification prior to adopting daily egg production stock assessment methods should be considered.

The native fucalean macroalga Carpophyllum flexuosum (Esper) Grev. has recently occupied many reefs on wave‐exposed coasts in north‐eastern New Zealand. At recently colonised sites, C. flexuosum occurs mainly on coralline‐dominated areas with moderate densities of sea urchins ( Evechinus chloroticus ). At these sites, stipes of C. flexuosum are shorter, with more branching, reduced laminae, and increased stipe weights compared...
