Worms were exposed to fixed daylengths (short-8h light: 16h dark; neutral-12h:12h; long-16h:8h), switched between different fixed daylengths, and switched from fixed daylengths to increasing or decreasing daylengths. Timing of parturition was synchronized when under neutral daylength, but became asynchronous under both short and long daylength, as well as when any of the fixed daylength was followed by decreasing daylenths. Worms under neutral daylength had the highest fecundities and shortest life spans, while those under long days had the lowest fecundities and longer life spans. When fixed daylength (short, neutral, long) was followed by increasing daylengths, timing of parturition was synchronized, fecundity was high, and life span shortened. These and earlier published experiments on the influence of seasonally changing photoperiods indicate that the life cycle of the estuarine N. limnicola is programmed to be completed in somewhat less than a year, and that seasonally changing photoperiods modulate it to determine the optimal time of parturition.10aREPRINT/PHOTOCOPY1 aFong, P., P.1 aPearse, J., S.  uhttps://annelida.myspecies.info/node/5000887nas a2200157   4500008004100000245016100041210006900202300002000271490000700291520030800298653002200606100001900628700002100647700001700668856004400685       1990                        eng d00aTaxonomy of the arboreal polychaete Lycastopsis catarractarum Feuerborn (Namanereidinae: Nereididae) with a discussion of the feeding biology of the species0 aTaxonomy of the arboreal polychaete Lycastopsis catarractarum Fe  a341-350,illustr0 v243 aLycastopsis catarractarum Feuerborn, 1931 is redescribed and a neotype designated.
