Kulunda Steppe

The first list of the rare grasshoppers of the Baraba and Kulunda steppes is presented. Two sets of distribution data are compared: (1) for the first half of 20th century and (2) for 1972–2019. A series of digital maps was generated by MapInfo 12.03. The distribution patterns of several species, namely Asiotmethis muricatus (Pallas), Notostaurus albicornis (Eversmann), Eremippus simplex (Eversmann), Myrmeleotettix antennatus (Fieber), Gomphocerippus rufus (Linnaeus), Mesasippus arenosus (Bey-Bienko), Mecostethus parapleurus (Hagenbach), Locusta migratoria Linnaeus, did not change significantly. Four taxa (Asiotmethis jubatus (Uvarov), Arcyptera fusca (Pallas), Stenobothrus carbonarius (Eversmann), Sphingonotus coerulipes Uvarov) were relatively often in the first half of 20th century and nowadays they are extremely rare. Two species, namely Megaulacobothrus aethalinus (Zubovsky) and Aeropedellus variegatus (Fischer de Waldheim), were recently found near the south-eastern and north-eastern boundaries of the region respectively. There are also the type localities of Asiotmethis jubatus and Mesasippus arenosus in the Kulunda steppe.

Bathymetric distribution data were compiled on benthic Medusozoa (Cnidaria) of the Bay of Biscay and nearby seas. The area of study extended from 42°N to 48°30′N, and westwards to 10°W. The depth range of each species was traced in a review of the literature. The number of species in each of several depth zones is summarized here: intertidal, intertidal–30 m, 30–100 m, and thereafter at 100 m depth intervals throughout the entire column (0–5000 m). Some 200 species were included (six Scyphozoa, four Staurozoa, 190 Hydrozoa). Of these, 196 could be ascribed to the Coastal Realm (0–200 m) (118 exclusives; 60% of the fauna) and Deep Benthic Realm (200+m) (31 exclusives;16%), with 47 species inhabiting both (24%). Eighty-eight species (45%) were present intertidally. Biodiversity was highest above the summer thermocline (30 m) (133 species, 67%), and no species have been recorded from depths greater than 4706 m. Beyond the thermocline, biodiversity dropped with increasing depth. A significant change occurred in the 30–100 m interval (123 to 78 species; Distinctiveness=51%), although all intervals down to the 300 m isobath exhibited substantial changes. Most species in the Deep Benthic Realm thrive on the upper part of the slope (200–800 m; 50 species). Biodiversity appeared homogeneous across wide bathymetric ranges in deep bathyal and abyssal regions, perhaps due to unique vertical biocenological units. Thus, 15 species are known between 1400 and 2000 m, and four between 3100 and 4300 m. Fifty-four species were considered eurybathic (34%), with some showing impressive bathymetric ranges of over 4000 m, but most species were stenobathic (106, 66%).As with data on benthic medusozoans from South Africa, the north-western Atlantic, the Arctic, and the warm western Atlantic (Bermuda), bathymetric biodiversity was highest in the first 100 m, with a substantial drop below that in species numbers on the shelf and at the beginning of the bathyal. While numbers of species may vary widely from one geographical region to another, such variations are due to differences in biodiversity in the upper 100 m. Hydroid species richness in the deep bathyal and abyssal is similar and always low. Worldwide, benthic medusozoan biodiversity is highest at shallow depths, and these organisms normally seem to be minor components of deep benthos. Very likely, the graph of biodiversity at increasing depth is similar worldwide for the Hydrozoa.

The considerable linguistic variety in the Iberian peninsula in the pre-Roman period was reflected in inscriptions on coinage. Greek and Punic scripts were used in the colonies and cities with settlers belonging to these cultural groups. The north-eastern Iberian signary was used in the Iberian area and was borrowed in order to write the Celtiberian language while south-eastern Iberian is recorded in the south-eastern quadrant of the Iberian peninsula, including parts of the provinces of both Hispania Citerior and Hispania Ulterior. The script known as Tartessian, south-western, or South Lusitanian, about which almost nothing is known, was used on the coinage issued by the mint of Salacia (Portugal). Roman control was the reason why Latin was adopted as the language used for coin legends by many cities in Turdetania from the early second century BCE. As from c.45 BCE, the native scripts disappeared from coin legends.
