Evaluation of various image transformation techniques for the delineation of coastal sand dune features in Tamil Nadu, South India

A study of geographic variation of maritime pine (Pinuspinaster Ait.) 9 years old, regarding height growth, transpiration and sap pressure daily kinetics has been performed in two sites, one in coastal sand dune and the other one in a more interior well-drained sandy moor. Successive height increments were measured from the 4th to the 9th year of growth and the year × provenance interaction was investigated. Transpiration and sap pressure were measured on 2-year-old needle fascicles. Results show discriminant variations between provenances and suggest some hypotheses about the possible ways of natural selection concerning drought resistance. The provenances North Landes (France) and Leiria (Portugal) grow best and strongly react to any variation of environmental factors as reflected by the high value of the slope of their regression lines (regression of their annual mean on the overall annual mean). Such a genotypie instability coincides with an intense physiologic activity (large flux of water correlated with a strong loss of weight by transpiration, reaching after 3 min 2% of the total dry weight of the separated needles and associated with the lowest sap pressure when the sun is around zenith). On the contrary, the Morocan provenance Tamjoute shows a large stability; its daily curves of transpiration and sap pressure reach early their maximum and minimum and therefore express a stress avoidance. Between these two extreme behaviours, the provenances Cazorla (south Spain) and Porto-Vecchio (Corsica) have intermediate values of transpiration and sap pressure, and their height growth shows a relative stability of response to environmental change.

The Odonata and physicochemical properties of freshwater streams, lakes, ponds and bogs in the sand-dune systems of Fraser, Moreton and North Stradbroke Islands and Cooloola, Queensland: and Wooli, New South Wales, are described. The odonate faunas of these dune masses show some differences from those of nearby areas, and there are close associations between some species and particular types of dune fresh water. Although no physicochemical characteristics were identified that might limit these dune dragonflies to their specific habitats, the lake-dwellers in particular may be useful indicators of environmental change.

The 16S Rrna Gene

Abstract An aerobic, Gram-stain-negative, non-motile, non-spore-forming, rod-shaped, and light pink-colored bacterial strain, designated TS19T, was isolated from a sand sample obtained from a coastal sand dune after exposure to 3 kGy of gamma radiation. Phylogenetic analysis based on the 16S rRNA gene sequences revealed that the isolate was a member of the genus Hymenobacter and was most closely related to H. wooponensis WM78T (98.3% similarity). Strain TS19T and H. wooponensis showed resistance to gamma radiation with D10 values (i.e., the dose required to reduce the bacterial population by tenfold) of 7.3 kGy and 3.5 kGy, respectively. The genome of strain TS19T consists of one contig with 4,879,662 bp and has a G+C content of 56.2%. The genome contains 3,955 protein coding sequences, 44 tRNAs, and 12 rRNAs. The predominant fatty acids of strain TS19T were iso-C15:0, summed feature 4 (iso-C17:1 I and/or anteiso-C17:1 B), summed feature 3 (C16:1 ω6c and/or C16:1 ω7c), and C16:1 ω5c. The major polar lipids were phosphatidylethanolamine, and one unknown aminophospholipid. The main respiratory quinone was menaquinone-7. Based on the phylogenetic, physiological, and chemotaxonomic characteristics, strain TS19T represents a novel species, for which the name Hymenobacter taeanensis sp. nov. is proposed. The type strain is TS19T (=KCTC 72897T =JCM 34023T).
