Abundance And Distribution

The biology, ecology and distribution of Pennant’s swimming crab (Portumnus latipes) along the coast of Portugal in 2015 was studied. Females dominated the catches and the highest percentage of berried females was recorded between February and April. Mean fecundity values were 7711, 10 004 and 4838 eggs for development stages I, II and III, respectively. Estimated Von Bertalanffy growth parameters ,Kand were 34.83 mm, 0.52 year−1and −0.41 year for males, and 27.16 mm, 0.74 year−1and −0.39 year for females, respectively.P. latipesis widely distributed along the Portuguese coast on sandy bottom to a maximum depth of 20 m, with the highest relative abundances from the south coast near estuaries and coastal lagoon inlets. Size distributions differed significantly () between the south and the southwest and northwest regions, with larger crabs in the south. Abundance was generally correlated with abundance ofDonax trunculusandDonax vittatus, supporting the hypothesis of a predator-prey relationship.

Cyclic Variations

AbstractLong-term cyclic variations in the distribution of prominences and intensities of green (530.3 nm) and red (637.4 nm) coronal emission lines over solar cycles 18–23 are presented. Polar prominence branches will reach the poles at different epochs in cycle 23: the north branch at the beginning in 2002 and the south branch a year later (2003), respectively. The local maxima of intensities in the green line show both poleward- and equatorward-migrating branches. The poleward branches will reach the poles around cycle maxima like prominences, while the equatorward branches show a duration of 18 years and will end in cycle minima (2007). The red corona shows mostly equatorward branches. The possibility that these branches begin to develop at high latitudes in the preceding cycles cannot be excluded.
