Latitudinal Range

Vanessa carye (Hübner, [1812]) has been reported to have a wide latitudinal range from Venezuela to the south of Chile (Patagonia). Populations are established at 3500 m in Putre region of Chile, with occasional observations around 4500 m. This article reports a new elevational record of V. carye above 5200 m located at the Sora Pata Lake, northeast of Caquena, in the highlands of the Chilean altiplano. This finding is the highest population ever reported for this migratory butterfly and one of the highest in the genus Vanessa.

Abstract The timing and duration of spawning and maturation schedules of Chrysophrys auratus were determined for populations in one subtropical (∼25°S on the upper west coast) and two temperate regions (∼32°S on the lower west and ∼35°S on the south coasts) over >2000 km of coastline along the west coast of Australia. This study thus encompassed the wide latitudinal range of this recreationally and commercially important sparid in this region. The results were used, in conjunction with previously published data, to explore traditional paradigms regarding the relationships between the reproductive characteristics and variations in water temperature. Spawning at each latitude occurred mainly at 19–21°C, but following a decline in temperature in the subtropical region and after a rise in temperature in the two temperate regions. Spawning on the upper west coast thus occurred between mid-autumn and early spring (∼7 months) as opposed to late winter to early summer on the lower west coast (∼6 months). Spawning on the south coast was mainly restricted to mid-spring to early summer (∼2–3 months) in 2003 and 2004 and did not occur in 2005 when temperatures in this period were the coldest on record. Thus, marked interannual differences in the prevalence of mature fish on the south coast probably reflect the “marginality” of the population. The length (L50) and age (A50) at which C. auratus matured increased markedly from 25 to 32°S. Studies such as this allow for latitudinal variations in reproductive characteristics to be incorporated into population models to optimize fisheries sustainable yield, and contribute towards appropriate spatial scales for sustainable management strategies (e.g. minimum legal lengths consistent with latitudinal variation in length-based maturity schedules). The narrow temperature range over which this species spawns accounts for its current latitudinal distribution and enables predictions of how this distribution might alter with climate change. This study provides relevant information for management and climate change implications for similar subtropical and temperate marine teleosts.

Pholadomya Sowerby, 1823 is an anomalodesmatan bivalve that dispersed during Mesozoic, like other Mollusks, colonizating the South Atlantic shallow seas, between Brazil and Africa. On brazilian Cretaceous the sources of Pholadomya are scarce, occurring in outcrops from Algodões Formation, Gramame Formation and Jandaíra Formation, where occurs the species Pholadomya baixaleitensis. Based on specimens from new outcrops of Jandaíra Formation, a new occurrence of P. cf. adversa and P. baixaleitensis are shown and a new morfotype for the genus is described. It was possible to infer that the species studied presented deep endobentonic habits, and burrowed slowly the sediment, probably living their whole life into the same cavity. During Campanian Pholadomya is known from Cameroon, France, Poland, Austria, Germany and other localities in United States of America, occurring in association with other tethyan mollusks. The records of the genus in the marginal equatorial basins enhance the fossil bivalve diversity, and agree with the hypotesis of a south latitudinal range for the Tethyan Realm during Upper Cretaceous.

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.
