Climate Proxies

Archival records and historical documents offer direct observation of weather and atmospheric conditions and have the highest temporal and spatial resolution, and precise dating, of the available climate proxies. They also provide information about variables such as temperature, precipitation and climate extremes, as well as floods, droughts and storms. The present work studied Arab-Islamic documentary sources covering the western Mediterranean region (documents written by Arab-Islamic historians that narrate social, political and religious history) available for the period AD 680–1815. They mostly provide information on hydrometeorological events. In Iberia the most intense droughts were reported during AD 747–753, AD 814–822, AD 846–847, AD 867–874 and AD 914–915 and in the Maghreb AD 867–873, AD 898–915, AD 1104–1147, AD 1280–1340 and AD 1720–1815 had prevalent drought conditions. Intense rain episodes are also reported.

AbstractThe pluviometric regime in the Western Mediterranean and concretely in Catalonia (NE Spain) is characterised by irregular amounts at monthly and annual scales, sometimes with copious short episodes causing floods and, conversely, sometimes with long dry spells exceeding 1 month length, depending on the chosen threshold level to define the dry episode. Taking advantage of a dense network of rain gauges, most of them with records length of 50–60 years and some others exceeding 85 years, the evolution of these monthly and annual amounts is quantified by means of their time trends, statistical significance and several irregularity parameters. In agreement with the evolution of the CO2 emissions into the atmosphere and the increasing concentration, in parts per million (ppm), of this greenhouse gas, different time trends at annual scale have been detected up to approximately years 1960–1970 in comparison with the interval 1960–1970 to nowadays. Consequently, besides the greenhouse effects on the temperature regime, the influence on the pluviometric regime could not be negligible. Graphical abstract

AbstractA Cecidomyiid gall midge, Cystiphora schmidti (Rübsaamen), lives on several related Chondrilla spp. occurring from Greece and eastern Europe to Iran. Its biology and host specificity were studied in the eastern Mediterranean region as part of the biological control programme against the weed C. juncea (Compositae, Cichoriaceae) in Australia. The adult female oviposits into the lower epidermis of the plant where small circular to ovoid raised galls are produced on the rosette, stem leaves and the stem. All the immature stages are completed inside the gall in 24–44 days, allowing 6–7 generations per year in southern Greece before low temperatures prevent development of overwintering larvae. The midge is heavily parasitised in Greece by two species of Eulophidae. Particularly in southern Greece, dense gall populations cover the leaves and stems of C. juncea, causing death of leaves, stunting and less seeding. Tests against 76 species of plants including some Cichoriaceae closely related to Chondrilla showed that Cystiphora schmidti is specific to the genus Chondrilla. Comparative tests with Cystiphora schmidti from Greece against four forms of Chondrilla juncea showed that the midge was adapted to its usual Greek host but was less closely adapted to a western Mediterranean form. The Greek strain of the midge readily attacked and thrived on the main Australian form of C. juncea.
