New light on UU Sagittae * [PDF]
New V and I band CCD photometry and medium resolution spectroscopy are used to derive the masses, luminosities and radii accurate to < 10% for the individual components of the eclipsing central star of the planetary nebula A63–UU Sge (M1 = 0.63 ± 0.06M⊙, R1 = 0.33 ± 0.01R⊙, M2 = 0.29 ± 0.04M⊙ and R2 = 0.53 ± 0.002R⊙).

Phylogenetic and ecological duality in the otoliths of Sciaenidae
Abstract Teleost fishes have evolved taxon‐specific otoliths that vary greatly in size and shape and are primarily involved in hearing and balance. This study identifies the main drivers of otolith shape disparity in Sciaenidae, a clade of sound‐producing bony fishes, using three‐dimensional geometric morphometrics (3DGM).

The 2001 Superoutburst of WZ Sagittae [PDF]
We report the results of a worldwide campaign to observe WZ Sagittae during its 2001 superoutburst. After a 23-year slumber at V=15.5, the star rose within 2 days to a peak brightness of 8.2, and showed a main eruption lasting 25 days. The return to quiescence was punctuated by 12 small eruptions, of ~1 mag amplitude and 2 day recurrence time; these ...

Studies on marine ecosystems rely on the identification of fish prey species of piscivores (fish, aquatic mammals, and aquatic birds) based on their bones and otoliths. The stomach contents of piscivores show predation on marine atherinids of commercial

ABSTRACT Fish stocking is a common management practice used to mitigate the effects of overfishing and other threats to wild fish populations. It is mainly employed in freshwater ecosystems with complex and variable strategies (different timings, fish lengths and origins), making its effectiveness challenging to assess.

Squids are important components of marine ecosystems because of their role as both predator and prey. Across the Tasman Sea, Gould's arrow squid (Nototodarus gouldi) is a commercially targeted ommastrephid squid that supports an economically important fishery.
