The 'type' of the fly species 'Trypeta' cylindrica Walker, 1853, from the William Saunders Collection, was misidentified and subsequently placed in the genus Chyliza Fallén (Psilidae). A specimen from the same collection with identical label data but belonging to Coelopacidia Enderlein (Tephritidae) is hereby identified as the correct holotype and the species should therefore be referred to as Coelopacidia cylindrica (Walker, 1853). Chyliza pallidipes Lamb, 1917 stat.

Microcystins produced by cyanobacteria pose a great threat to human health by releasing toxins upon cell death. In the present study, we studied microcystin production in the cyanobacterial strains (B629 and 2949) and (SF33) exposed to 1, 2 and 4 g/L sodium chloride (NaCl). Cultures grown for 7 days in BG11/HEPES medium were pelleted, re-grown in the corresponding NaCl levels, and enzyme linked immunosorbent assay (ELISA) performed.

Many animal populations display consistent individual differences in suites of correlated behaviours. While these so called 'animal personalities' can substantially influence the ecology and evolution of populations, little is known about cross-sex correlations of behaviour and thus the potential of personality to limit sex-specific behavioural adaptations. Here, we experimentally induced sex-change in the sequentially hermaphroditic reef fish Parapercis cylindrica and demonstrate the existence of tight cross-sex correlations for two behaviours with presumed different sex-specific optima.

Positive density dependence (i.e., the Allee effect; AE) often has important implications for the dynamics and conservation of populations.

Sexual selection explains sex-specific growth plasticity and positive allometry for sexual size dimorphism in a reef fish.

In 1950, Rensch noted that in clades where males are the larger sex, sexual size dimorphism (SSD) tends to be more pronounced in larger species. This fundamental allometric relationship is now known as 'Rensch's rule'. While most researchers attribute Rensch's rule to sexual selection for male size, experimental evidence is lacking.
