Figure 1
Distribution map and spawning periodicities of Diadema setosum.
Locations of known spawning times are indicated by dots. Radial plots indicate estimated spawning periods (black portions) for each location. The plots are constructed of 12 equally sized slices representing the monthly annual cycle from January to December (clockwise). In sites of continuous year-round spawning, peak spawning months are indicated by asterisk (if such distinction was mentioned in the literature). Distribution estimates were based on: Pearse12,57; Clark and Rowe58; Marsh and Marshall59; Rowe and Gates60; Shin61; Lessios et al.4; James62; Sastry63; Yokes and Galil64; Nader and El Indary65 as well as data available from the OBIS website (http://www.iobis.org/home). Lowercase letters indicate the underlying publication of spawning periodicities for the particular location (only publications specifically referring to spawning periodicities were considered for the construction of this map). a: Kenya - Muthiga18; b: Al-Ghardaqa - Pearse10; c: Wadi-el-Dom (Gulf of Suez)- Pearse10; d: Port Tawtiq (Gulf of Suez) - Fox46; e: Eilat (Gulf of Aqaba)- this study; f: Kuwait - Alsaffar and Lone17; g: Sichang (Thailand)- Kobayashi45 (report of spawning in a two month study during February and March) ; h: Seto (Japan)- Onoda66, Kobayashi and Nakamura67; i: Misaki (Japan)- Yoshida30; j: Philippines - Tuason and Gomez44; k: Singapore - Hori et al.31; l: Low Isles (Great Barrier Reef) - Stephenson68; m: Rabaul (New Britain Island) - Pearse12 (report of spawning by field observations on 24.02.1965 based on pers. comm. from J. J. Gonor); n: Fiji - Coppard and Campbell14.
