We also recorded and compared a series of life-history traits, including the onset and end of aestivation, copulation, oviposition, and hatching. Our aim was to obtain more information on the ecology of Albinaria, to reveal possible life-history patterns, and to understand the association of life-history characteristics with both extrinsic (density independent) and intrinsic (density dependent) factors and microevolutionary processes. The onset of aestivation period occurs always in April and is independent of the end of rainfall, whereas awakening and copulation is actually synchronous and occurs after the first autumn rains. The duration of the oviposition and hatching period is short, but oviposition can be prolonged under favourable climatic conditions. Density is high, but its fluctuations were not related to climatic or time factors. Any density dependent pattern resulting from competition was not detected. Higher mortality did not coincide with aestivation, and usually relatively high mortality results after hatching. Juveniles usually exhibit higher mortality than adults. Spatial distribution of these rock-dwelling snails is always highly contagious. Clustering behaviour was probably influenced by the substratum, mosaic or uniform, and the occurrence of crevices. Predictions about the population dynamics of these iteroparous, long-lived species were not possible because of sampling inadequacies and/or because fluctuations of population structure, density, mortality and spatial distribution were random.}, keywords = {Albinaria, density, Greece, life history, Mollusca, mortality, Spatial distribution}, author = {Giokas, S. and Mylonas, M.} } @article {13496, title = {On the life-history of Barbus peloponnesius and Barbus cyclolepis in Macedonia, Greece}, journal = {Folia ZoologicaFolia Zoologica}, volume = {54}, number = {3}, year = {2005}, note = {Export Date: 4 September 2006Source: ScopusReferences: Adams, P.B., Life history patterns in marine fishes and their consequences for fisheries management (1980) U.S. Fish.

In both species, after the first year of life, females exhibited longer mean lengths at age and greater maximum length than the males, while between species B. cyclolepis showed greater mean lengths at age and greater maximum length than B. peloponnesius.

Significant difference in the sex ratio was found only for B. cyclolepis and this species population was male dominated. Gonad maturation began at the age of 1+ in males and 3+ in females of both species. Both species exhibited a protracted multi-spawning season, which started at the end of March-beginning of April and lasted until mid July. Despite differences in growth and body size, the two species are characterized by similar life-history styles: (1) similar age structure, (2) early maturation and same age at maturity, (3) males have a shorter life span, higher rate of mortality, decreased growth and smaller body size and mature earlier than the females and (4) elongated multi-spawning season, which shows a high investment in reproduction.

In an attempt to explain the presence of the various species, modes and ecological consequences of Quaternary island colonization by large mammals and man in the Mediterranean are discusssed from a hypothetical point of view, as are the reasons for the extinction of the Quaternary fauna. Small arboricole mammals may have reached the islands on vegetation-rafts. Some larger mammals, like Myotragus on the Balearic Islands, Prolagus on Sardinia, and possibly endemic deer on the Aegean islands, could be relics of the desiccation of the Mediterranean on the Mio/Pliocene border. Hippos, elephants and giant deer reached the islands by swimming. At the arrival of new species, older endemic species became extinct by ecological competition. Overpopulation consisting of a single or few species with corresponding damages to the vegetation led to dwarfing and an adaptation to hard foods. Because of the lack of carnivores, the genetically fixed behaviour patterns for flight and attack are lost in island endemics. During the Middle (Corso-Sardinia) and Upper Pleistocene, suspected or established (Sardinia, Cyprus, Sicily) invasions of Homo sp. led to the near-complete extinction of the unwary endemic fauna. Some islands (Sicily, Corso-Sardinia) were repopulated by swimming ungulates which were exterminated by later human invasions. For lack of game, a permanent human settlement was nearly impossible before the Neolithic.

A time-variant, stage-classified, matrix population model was developed to interpret the seasonal variation of octopus stage densities and to estimate several life cycle parameters. An annual and a semi-annual periodic cycle were found in the stage densities. A main peak of benthic settlement was observed during summer and a secondary, irregular one during late autumn. Two spawning peaks were estimated, a main one during late winter-spring and a secondary one during late summer-early autumn. More than 50\% of the just-settled individuals will eventually die after 3 months. Mortality rate declines, as individuals grow larger, reaches a minimum approximately 6 months after settlement, and then grows again probably because of terminal spawning. The life expectancy of recently settled individuals (<50 g) during their summer peak is approximately 5 months. The lifespan of the common octopus is estimated to be between 12 and 15 months.

The results indicated that the distribution of S. oleae was highly aggregated and the degree of aggregation changed considerably during the generation, as indicated by the values of the exponent k of negative binomial distribution and the I{\"a} index of aggregation. Aggregation increased during the ovipositional period in summer and during winter, whereas it decreased during autumn and spring. The increased aggregation during summer was caused by the combined effect of crawler behavior as they searched for settlement, and of mortality, which is negatively related to population density. During autumn, and possibly during spring when the main action of natural enemies occurred, the reduced aggregation was caused by the direct density dependence of mortality. This relationship was determined to a certain extent by the action of the internal parasitoid Metaphycus helvolus (Compere). The increased aggregation during winter was attributed to an inverse density-dependent relationship between mortality and population density and also to larval movement from leaves to branches. A strong relationship between the mean and variance of population density (Taylor power law) was established with 2 types of sampling units (leaf, branch). The corresponding 2 values of the coefficient b were remarkably similar. However, the exponent k of negative binomial and the Morisita index of aggregation (I{\"a}) were found best to describe changes in the spatial pattern during the generation compared with the Taylor relationship.}, keywords = {mortality, Saissetia oleae, Spatial pattern}, author = {Kapatos, E.T. and Stratopoulou, E.T. and Sahinoglou, A.} } @booklet {7194, title = {Age, growth, mortality, reproduction, and feeding habits of the striped seabream, Lithognathus mormyrus (Pisces: Sparidae), in the coastal waters of the Thracian Sea, Greece}, howpublished = {Scientia MarinaScientia Marina}, volume = {69}, number = {3}, year = {2005}, note = {Export Date: 4 September 2006Source: ScopusReferences: Anderson, R.O., Neumann, R.M., Length, weight, and associated structural indices (1996) Fisheries Techniques, pp. 447-481. , Murphy B.R. and D.

Prey analyses of stomach contents identified 15 important items (\%Rn > 0.05) belonging to six major groups: crustacean (copepods, cladocera), mollusca (bivalve: larvae), insects (larvae), cestode worms and finfish (fry and eggs). Dominant prey were larvae of the bivalve Dreissena polymorpha (\%Rn = 33.8), the copepods Eudiadomus drieschi (\%Rn = 26.4) and the cladocera Diaphanosoma brachyurum (\%Rn = 24.2). The importance of cladocera and copepods decreased with increasing size of the sand smelt, while the importance of bivalve larvae, fish eggs and finfish fry increased with increasing sand smelt size. Seasonal changes in diet composition and prey abundance in sand smelt stomachs were recorded as coinciding with the seasonal composition and abundance of the zooplankton community in the surface layers of Trichonis Lake. Bivalve larvae were the dominant prey of A. boyeri during January to May, while copepods and cladocera dominated from June to December.}, keywords = {age, estuary, fishes, growth, lagoon, mortality, Pisces, population, river}, isbn = {0175-8659}, author = {Chrisafi, E. and Kaspiris, P. and Katselis, G.} } @article {3103, title = {Effectiveness of spinosad dust against different European populations of the confused flour beetle, Tribolium confusum Jacquelin du Val}, journal = {Journal of Stored Products ResearchJournal of Stored Products ResearchJournal of Stored Products Research}, volume = {44}, number = {1}, year = {2008}, note = {ISI Document Delivery No.: 253JKTimes Cited: 6Cited Reference Count: 30}, pages = {47-51}, type = {Article}, abstract = {Six populations of the confused flour beetle, Tribolium confusum, obtained from Greece, Italy, Portugal, Denmark, Germany and France were tested for their susceptibility to a spinosad dust formulation, containing 0.125\% spinosad. For this purpose, adults and larvae of T confusum were exposed on wheat treated with two dose rates of the dust formulation, 0.06 and 0.19 ppm of a.i. corresponding to 50 and 150 ppm of the formulation, at 25 degrees C and 65\% Hi. Mortality of the exposed individuals was assessed after 7, 14 and 21 days of exposure on the treated substrate. The increase of dose and exposure interval increased mortality, while adults were more tolerant to spinosad than larvae. Significant differences were noted among populations, for both adults and larvae. The most tolerant to spinosad was the strain from Greece, while the least tolerant were the strains from Germany and Denmark. After 7 days of exposure, on wheat treated with 50 ppm, mortalities of adults of the Greek, German and Danish strains were 2\%, 25\% and 62\% respectively, while the respective figures for 150 ppm were 1 \%, 31 \% and 81 \% respectively. In the case of larvae, of the same strains, mortality at 50 ppm was 6\%, 27\% and 28\% and at 150 ppm 11 \%, 23\% and 40\%, respectively. The results of the present study suggest that different strains and stages of T confusum differ widely in their susceptibility to spinosad-treated wheat. (c) 2007 Elsevier Ltd.

From 1990 to 1992, an epizootic produced a massive die-off of striped dolphins in the Mediterranean Sea. The event\ started in mid-Spain but extended, through three apparently\ interconnected outbreaks, to finally coverthe whole western\ Mediterranean and the Tyrrhenian and Aegean Seas.\ Although more than 1000 carcasses of striped dolphins\ were collected during the event, the total toll remains\ unknown because of fragmentary coverage of rescue\ networks and because many carcasses never reached the\ shore. The primary cause of the episode was identified as\ an infection by a morbillivirus, the origin of which could not\ be ascertained. The dolphins affected were found to carry\ concentrations of pollutants higher than normal for the\ general population. This difference could not be explained\ by variation in nutritive condition or by sex or age composition.\ The dolphins that died at the beginning of the outbreak were\ in abnormally poor nutritional condition, and had increased\ prevalence of ectoparasites and epizoits. This suggested\ that these dolphins had recently undergone a period of\ restricted mobility, during which the ectoparasites had found\ attachment easier than under normal conditions. Abnormal\ weatherconditions, leading to depressed marine productivity,\ may have been the cause of some of these anomalies.
