Fig. 5: Distribution and abundance maps of eggs during May (A, B) and July 2010 (C-E), in the NE Aegean Sea. The major patches are indicated by different colours, while the size of the circles is scaled by the maximum abundance per species and period (Table 2). The number of each patch indicates the ranking according to the abundance of individuals in each patch. The small black cross symbols show the centres of gravity (CG) of each major patch (i.e. those patches having more than 10% of the overall abundance; Table 3). The large cross indicates the CG of the population. The length of the cross axes indicate the isotropy of the egg distribution. The 200m isobaths are also shown (dark contour line).

Fig. 4: Box-and-whisker plots for temperature (oC; at 10 m depth), salinity (at 10 m depth), log-transformed integrated fluorescence (μg l-1) and log-transformed mesozooplankton biomass (mg m-2) between three groups of sampling stations: L – Lemnos plateau, O – offshore pelagic area north of Lemnos island, and T- Thracian Sea shelf. Boxes indicate median and interquartile ranges, whiskers delineate full ranges. F-values are provided for comparisons of the parameters between the three groups (L, O, T) and within each season. For comparisons that did not meet the assumptions of the analysis of variance, the Kruskal-Wallis statistic H is provided. Asterisks indicate significant differences: *p <0.05, **p <0.01, ***p <0.001. Post-hoc multiple comparisons were performed with a Student-Newman-Keul's test, where statistically significant differences among groups are indicated by letters a, b, c on the left side of each box. Groups with the same letter do not differ significantly.

Data from: Same school, different conduct: rates of multiple paternity vary within a mixed-species breeding school of semi-pelagic cichlid fish (Cyprichromis spp.)

Mating system variability is known to exist between and within species, often due to environmental influences. An open question is whether, vice versa, similar environmental conditions entail congruent mating behavior, for example in terms of multiple paternity, in species or populations sharing largely comparable breeding modes. This study employed microsatellite markers to investigate the incidence of multiple paternity in Cyprichromis coloratus and Cyprichromis leptosoma, two sympatric, closely related, mouthbrooding Lake Tanganyika cichlids with similar ecological and behavioral characteristics including the formation of open-water schools. Mouthbrooding females of both species were collected from the same mixed-species breeding school at the same time, minimizing environmental variation during courtship and mating. In C. coloratus, four of 12 broods had more than one sire, with a mean of 1.33 reconstructed sires per brood. C. leptosoma exhibited multiple paternity in 18 of 22 broods, with a mean of 2.59 or 2.86 reconstructed sires per brood according to the programs gerud and colony, respectively. In addition, two broods were found to contain offspring transplanted from another brood. There was no significant difference in brood size between species, but mean sire number did differ significantly. Hence, substantial similarity in reproductive behavior along with shared environmental conditions during courtship and spawning did not lead to equal rates of polyandry or sneaking in the two species.

Head-body 46:5-47-8 cm (males), 44-45-5 cm (females), tail 40-43 cm (males), 38-39 cm (females), hindfoot 8:7-9-8 cm (males), 8-9 cm (females), ear 4-7-5-4 cm (males), 5-1-5-8 cm (females); weight 1-3-2 kg. The coat color is pale ocher, with brownish or grayish tones; melanistic individuals are quite common. The throat and chest are blackish, and the ventral pelage varies from creamy white to dirty white. The stripes and spots on the body vary from different hues of brown to black. The nuchal stripes run as two parallel lines from the nape to the shoulders, where they diverge and enlarge towards the elbows; they are not so conspicuously marked as in other genet species. Below them, a pair of thinner stripes and small spots are scattered on the shoulders and sides of the neck. A third pair of thinner, parallel stripes runs down the neck between the nuchal stripes, extending to about one fourth of the mid-dorsal line, where they vanish or diverge as the first row of flank spots. The black mid-dorsal line is continuous and is flanked on each side by four rows of oblong to squared spots, and by a few small-scattered spots below. There is a dorsal erectile crest. The face has a dark mask and a pair of white sub-ocular spots. The tail has seven to nine black rings, alternating with pale rings; the intervening white spaces are pigmented with a brownish tinge on the dorsal midline. The width of the pale rings relative to the dark rings in the middle of the tail is 50-75%; the tip of the tail is dark. The hindlimbs and forelimbs are black; there are white hairs on the metacarpals and metatarsals. [he posterior parts of the feet are dark. There are two pairs of teats. The posterior chamber of the auditory bulla is not ventrally inflated and has a continuous curve line on the external side. The ratio between the inter-orbital constriction and frontal width is 1-00 + 0-12. Dental formula: 13/3, C1/1,P 4/4, M 2/2 = 40. in Viverridae

Gressitt's Mosaic-tailed Rat is a medium-sized Paramelomys with a soft, thick and woolly pelage, a long narrow foot, and a tail with three hairs per scale. It exhibits a medium-sepia dorsal pelage and a gray-buff ventral one. Tail is slightly shorter (99%) than head-body length. The skull has a narrow zygomatic plate. Habitat. Moist tropical mountain forest between 2300 m and 2400 m. Food and Feeding. No information. Breeding. No information. Activity patterns. Gressitt's Mosaic-tailed Rat is terrestrial.
