Dorsal mantle length (DML) ranged from 24 mm to 360 mm and body weight (BW) from 2.4 g to 1630 g. Modal progression analysis (MPA) indicated a female life span of 13-18 mo and in male life span of 11 mo. Length-weight relationship was found to be positively allometric for males and negatively allometric for females in all three populations. Sex ratio did not differ significantly from 1:1 over the entire sampling period. Differences among the three populations were observed for the following life-cycle parameters: (1) males from the Portuguese waters had significantly different length-weight slopes from those from the remainder areas; (2) size at full recruitment was determined at 110 mm in females from the Portuguese waters whereas in females from the Southern Celtic Sea and Bay of Biscay and from the Greek Seas was 170 mm; (3) female recruitment peaks were recorded only during autumn in samples from the Southern Celtic Sea and Bay of Biscay while in those from the Portuguese waters and the Greek Seas the recruitment peaks were recorded at various seasons; (4) maturing and mature males were found abundantly over the entire sampling period in the samples from the Southern Celtic Sea and Bay of Biscay and the Greek Seas whereas in those from the Portuguese waters maturing and mature males were at higher percentages than immature ones only during spring and summer; peaks of the Gonadosomatic index, calculated for mature females from the Southern Celtic Sea and Bay of Biscay, were scored from February to April of 1998 and 1999 and during September of 1998 while in the samples from the Greek waters during April and August 1998 and during January and May 1999; (5) L50 (mantle length at which 50% of the individuals are mature) values estimated for both females and males from the three studied areas were gradually decreased from the North Atlantic to the Mediterranean; (6) length data suggest that females from the Greek Seas potentially mature at two modal sizes while those from the remainder areas show only one modal size at maturity. Environmental variables (sea surface temperature and chlorophyll-a concentration) were correlated with some of the biological indices of the I. coindetii populations. Finally, results on biological indices of the I. coindetii are compared with those calculated for its congeneric species I. illecebrosus, I. argentinus as well as with another European ommastrephid species Todaropsis eblanae. |

In addition, correspondence analysis of eight qualitative characters was performed. The results showed that, though body length had an inconsistent pattern of intersexual variation across taxa, other traits contributed to statistically significant level of SSD. The analysis on multivariate level revealed a highly significant effect of population in all three taxa, and significant effect of sex on character variation. Discriminant analysis confirmed a higher level of intersexual differences in B. variegata compared to B. bombina. Correspondence analysis showed that females and males were similar with respect to qualitative traits in all three taxa. At the univariate level, the most prominent features were: significant differences in tibia length in all three taxa, and highly significant differences in head width in B. bombina and in humerus length in B. v. scabra. These results are discussed with respect to specific reproductive behaviour and possible ecological differences between sexes.}, keywords = {}, pubstate = {published}, tppubtype = {article} } The direction and level of sexual size dimorphism (SSD) was examined in fire-bellied toads from the central Balkans.

The average concentrations of total PCB congeners (∑PCBs) in the gas and particulate phases of the atmosphere were 68.1 ± 28.8 and 2.3 ± 1.8 pg/m3, respectively. The lack of seasonal variation for the atmospheric concentration of individual congeners and ∑PCBs and the shallow slopes obtained from the Clausius-Clapeyron (CC) plots for several PCB congeners indicated that long-range transport is the main factor controlling the atmospheric levels of PCBs in this area. Most of the episodes with elevated concentrations of ∑PCBs concurred with air transport from western and central Europe. This observation was mostly attributed to the predominance of N-NW winds in eastern Mediterranean. The wind speed apparently did not affect the atmospheric concentration of PCBs. Significant changes observed on the homologue group profile of PCBs were mostly related to the origin of air parcels sampled and during summer were most probably related to the reaction of the lighter congeners with OH radicals. Partitioning of PCBs between gas and particulate phases was well correlated with the subcooled liquid vapor pressure (PLo) for 11 of the 37 samples.
