THE ROLE OF SOLUABLE CARBOHYDRATES IN HALOPHYTES OF THE AREA OF THE NEUSIEDLER LAKE, AUSTRIA. OECOLGIA PLANTARUM 13.1 27-42 1978 DE ART AUSTRIA THE PATTERN OF SOLUBLE CARBOHYDRATES IN HALOPHYTES: CRYPSIS ACULEATA, PUCCINELLIA DISTANS, BOLBOSCHOENUS MARITIMUS, JUNCUS GERARDII, AGROSTIS STOLONIFERA, PHRAGMITES AUSTRALIS, CAREX DISTANS, TRIGLOCHIN MARITIMUM, SPERGULARIA MEDIA, CHENOPODIUM SPP., ATRIPLEX HASTATA, CAMPHOROSMA ANNUA, SUAEDA SPP.,SALCORNIIA PROSTRATA, LEPIDIUM CRASSIFOLIUM, PLANTAGO MARITIMA, SONCHUS ARVENSIS, ASTER TRIPOLIUM SSP. PANNONICUS, AND ARTEMISIA MONOGYNA. FROM THE REGION EAST OF NEUSIEDLER LAKE IN AUSTRIA WAS INVESTIGATED. THE TOTAL SUGAR CONC IN THE CELL SAP OF MONOCOTS RANGE BETWEEN 154 AND 213 MMOL 1-1 FRESH WATER AND EXCEED BY FAR THE CONC IN DICOTS (19-85 MMOL 1-1;EXCEPT A. MONOGYNA:132 MMOL 1-1). APART FROM PRONOUNCED SALT ACCUMULATORS, THE TOTAL OSMOTIC POTENTIALS LIE AS LOW IN MONOCOTS AS IN MOST DICOTS, IN SPITE OF SALT UPTAKE OF FORMER SPECIES. ACCORDINGLY, IN MONOCOTS THE PERCENTAGES OF SOLUBLE CARBOHYDRATES OF THE TOTAL OSMOTIC POTENTIALS MOUNT UP TO VALUES AS HIGH AS 25-36% WHEREAS %'S IN DICOT HALOPHYTES REMAIN LOW (2-12%). THE HIGH SUGAR CONTENT OF MONOCOTS IS CONSIDERED TO BE OF ECO-PHYSIOLOGICAL IMPORTANCE, SINCE IT MAKES POSSIBLE THE GROWTH OF SUCH PLANTS ON SALINE SOILS HAVING LOW WATER POTENTIAL WITHOUT EXTENSIVE SALT ACCUMULATION.

WAS LIMITED TO HIGHLY WEATHERED SOILS OF LOW EXCHANGEABLE-CATION CONTENT AND HIGH ACIDITY. CAMPO SUJO VEGETATION (A SECONDARY ASSOCIATION DOMINATED BY PTERIDIUM AQUILINUM, BANISTERIA CROTONIFOLIA, ETC.) OCCURED ON SIMILAR SOILS, BUT WITH HIGHER P AND MN AND LOWER SESQUIOXIDES CONTENTS. THE SOILS OF PALM SAVANNAHS (ACROCOMIA) AND FOREST FORMATIONS WERE RELATIVELY RICH IN EXCHANGEABLE CATIONS AND HAD HIGHER PH VALUES. THE TYPICAL CERRADO TREES ARE EITHER TRUE ACIDOPHILOUS OR CALCIPHOBOUS PLANTS OR THEY MAY BE UNABLE TO COMPETE WITH PLANTS WHICH GROW VIGOROUSLY ON SOILS OF HIGHER PH AND BETTER FERTILITY.

THE SPECIMENS WERE ORIGINALLY COLLECTED FROM ALL PARTS OF THE TROPICAL AND WARM-TEMPERATE WORLD BETWEEN LATITUDES 40'N AND 40'S. THE SURVEY RESULTED IN THE RE-IDENTIFICATION OF ALL PREVIOUSLY KNOWN HYPERACCUMULATORS (>1000 UG/G DW BASIS) OF NICKEL (5 SPECIES) AND IN THE DISCOVERY OF 5 ADDITIONAL SPECIES (ALL FROM NEW CALEDONIA) FROM THESE TWO GENERA. FOURTEEN PREVIOUSLY UNKNOWN STRONG ACCUMULATORS (100-1000 UG/G) OF NICKEL WER ALSO DISCOVERED, MOST OF WHICH WERE GROWING OVER ULTRABASIC ROCKS.

DEFICIENCY DISEASES IN THE COW, APARANTLY CAN ARISE THROUGH TH CONSUMPTION OF FODDER OF LIMITED BOTANICAL COMPOSITION. AN ENRICHMENT OF SUCH SWARDS BY HERBACEOUS SPECIES WOULD INCREASE MINERALS AND CHLOROPHYLL. THE HERBS ARE GENERALLY PROVED TO BE ESPECIALLY RICH IN MINERALS AND ARE THEREFORE SUITABLE FOR REGULATING THE MINERAL RELATIONS OF RATIONS.

ECOLOGY 42 173-176 1961 EN 12 ART USA NM Y Y CRESTED WHEATGRASS (AGROPYRON DESERTORUM) HAS A MORE OR LESS PERPENDICULAR GROWTH FORM WHEN NOT GRAZED. ON DRY SITES, CRESTED WHEATGRASS IS MORE SPREADING THAN ON MOIST AREAS GRAZED AT SIMILAR INTENSITIES. GROWTH FORM BECOMES PROGRESSIVELY MORE SPREADING WITH INCREASED INTENSITIES OF CATTLE GRAZING UNTIL A PROSTRATE FORM MAY RESULT UNDER GRAZING WHERE 70% OR MORE OF THE HERBAGE IS REMOVED EARLY. PAST INTENSITY OF CATTLE GRAZING HAS A GREATER EFFECT UPON THE GROWTH FORM THAN DOES SITE.

SOIL CONSERVATION SERVICE NATIVE VEGETATION AS A CRITERION FOR DETERMINING CORRECT RANGE MANAGEMENT AND RUN-OFF CHARACTERISTICS OF GRAZING LANDS. JOURNAL OF FORESTRY 39 837-824 1941 EN 5 ART SW USA Y Y THE RECOGNITION OF RANGE CONDITIONS IS FACILITATED BY AN ACCURATE ANALYSIS OF THE VEGETATION AND THE DEGREE OF DETERIORATION FROM THE CLIMAX OR THE HIGHEST TYPE OF VEGETATION THE AREA WOULD NATURALLY SUPPORT; THE PRESCRIPTION OF CORRECTIVE MEASURES REQUIRES THAT THE VARIOUS DEGREES OF DETERIORATION OR RANGE CONDITION BE CLASSIFIED. SIX RANGE CONDITIONS, FROM EXCELLENT TO VERY POOR, ARE USED FOR RANGE PLANNING BY THE SOIL CONSERVATION SERVICE AND ARE PARTICULARLY ADAPED TO CLASSIFYING RANGE LANDS ON AN ARIAL BASIS. CORRECT FUTURE MANAGEMENT PRACTICES ARE GIVEN FOR THE SIX DIFFERENT CONDITION CLASSES.

BOTANICHESKII ZHURNAL 49.8 1119-1132 1964 RU EN ART RUSSIA Y Y A POSSIBILITY IS DISCUSSED OF USING THE ABUNDANCE OF NITROPHILOUS PLANTS IN COENOSES, AS WELL AS VARIOUS INDEXES OF THIER VIGOR, AS QUANTITATIVE INDICATORS OF THE NITRATE CONTENT OF THE SOIL. IT WAS ESTABLISHED THAT ANY ONE OF THESE INDICATORS IS NOT ALWAYS RELIABLE WHEN IT IS CONSIDEEERED ALONE, APART FROM ALL THE OTHERS; IT MIGHT GIVE A SOMEWHAT ERRONEOUS IDEA ABOUT THE ENERGY OF THE PROCESS OF NITRIFICATION PROCEEDING UNDER THE VEGETATIONAL COVER; BUT NEVERTHELESS, EACH OF THEM DOES NOT MERELY DUPLICATE THE EVIDENCE AFFORDED BY OTHER INDICATORS, IT SUPPLEMENTS THIS EVIDENCE AND CONTRIBUTES TO ITS PRECISION. CONSEQUENTLY THE USE OF THE ENTIIRE COMPLEX OF THE CHARACTERISTICS OF THE VEGETATIONAL COVER SERVING AS THE INDICATORS OF THE NITRATE CONTENT PERMITS ONE TO OBTAIN EVEN A MORE COMPLETE AND RELIABLE ESTIMATE OF THE REGIME OF NITRATES IN THE SOIL, THAN THAT BASED ON THE DATA OF THE DIRECT SOIL ANALYSIS.

THESE FACTS SEEM TO CORRELATE CLOSELY WITH THE DIFFERENCES OF LEAF SENESCENSE AND BROWN SPOT APPEARANCE. THE SENSITIVE RESPONSE OF INDICA TYPES TO REDUCED PADDY FIELD CONDITIONS SUGGESTS THE POSSIBILITY OF UTILIZING THEM AS PLANT INDICATORS TO DIAGNOSE THE REDOX STATE OF THE SOIL UNDER RICE CULTURE.

SSR, BIOL 1 28-37 1965 RU ART RUSSIA ? ? IN THE ORE BEARING REGION OF CENTRAL KARATAU THE ZN CONTENT OF THE VEGETATION IS INDICATIVE OF THE PRESENCE OR ABSENCE OF ZN DEPOSITS, BUT THE PB CONTENT OF THE VEGETATION IS LESS DIAGNOSTIC FOR PB DEPOSITS BECAUSE PB IS NOT ACCUMULATED BIOLOGICALLY. THE ZN CONTENT OF THE VEGETATION CAN INDICATE THE OCCURANCE OF PB DEPOSITS WHEN THE LATTER ALSO CARRY ZN. THE SOIL IS A BETTER INDICATOR OF PB THAN OF ZN, BECAUSE ZN MIGRATES INTENSIVELY BEYOND THE SOIL PROFILE. IN ANALYSING SOIL FOR PB, THE COARSE FRACTION OF THE UPPER HORIZONS SHOULD BE USED. INCREASING MN CONTENT WITH SOIL DEPTH CAN INDICATE MINERALIZATION OF PB IN ROCK OCCURING IN ITS PLACE OF ORIGIN. COMBINATION OF MN WITH OTHER SECONDARY ORE MINERALS ALTERS THE MORPHOLOGY OF THE SOIL PROFILE AND ALLOWS SOIL FORMED ABOVE OREBEARING ROCK TO BE CLEARLY DIFFERENTIATED FROM SOIL ABOVE ROCK THAT DOES NOT FORM ORE.

CHANGES IN BOTANICAL COMPOSITION IN 1856-1976 ARE OUTLINED. WHERE NO N WAS APPLIED, THE NUMBER OF SPP. DECLINED FROM C.50 TO AN AV. OF 37. GRASS CONTENT DECLINED FROM 76% TO C.50%, LEGUME CONTENT REMAINED AT C.7% AND OTHER SPP. INCREASED FROM 20% TO C.40% WITH A TENDENCY FOR LEONTODON DISPIDUS, PLANTAGO LANCEOLATA AND POTERIUM SANGUISORBA TO BECOME DOMINANT. THE LARGEST RECENT CHANGE ON THE UNMANURED PLOT WAS AN INCREASE IN RED FESCUE, TO ABOUT 30% OF THE HERBAGE. PKNAMG REDUCED LEGUMES AND INCREASED FESCUE AND AGROSTIS SPP. WITH LIME, ARRHENATHERUM ELATIUS INCREASED TO C. 30% OF THE HERBAGE. ON UNLIMED PLOTS RECIEVING (NH4)2SO4, ACID TOLERANT GRASSES BECAME DOMINANT, THE SPP. DEPENDING ON RATE OF N AND APPLICATION OF PKNAMG. ANALYSES IN 1975-6 SHOWED ON INCREASE OF A. ELATIUS ON THE LIMED HALVES OF (NH4)2SO4 PLOTS. WHERE NANO3 WAS APPLIED THE VEGETATION REMAINED RELATIVELY STABLE WITH C.30 SPP. NEW LIMING TREATMENTS REDUCED AGROSTIS CONTENT OF NKNAMG PLOTS, INCREASED FESCUE AND TREBLED DM YIELD. AT AN INTERMEDIATE N RATE, LIMING INCREASED FESCUE, YORKSHIRE FOG AND POA PRATENSIS. AT THE HIGHEST N RATE, LIMING REDUCED YORKSHIRE FOG AND INCREASED A ELATIUS, P. PRATENSIS, A.

EACH SPECIES PARTITIONED LESS THAN 2% OF ITS DRY WEIGHT INTO FLORAL FORMATION. HOWEVER YELLOW NUTSEDGE (C. ESCULENTUS L.) PARTITIONED ONLY 28% OF ITS DRY WEIGHT TO TUBERS, WHEREAS PURPLE NUTSEDGE (C. ROTUNDUS) PARTITIONED 50% OF ITS DRY WEIGHT TO FEWER AND LARGER TUBERS. THE ALLOCATION OF DRY WEIGHT TO REPRODUCTIVE STRUCTURES WAS RELATED TO CHANGES IN DAY-LENGTH. YELLOW NUTSEDGE TUBER FORMATION INCREASED AS DAY-LENGTH DECREASED FROM 14.5 TO 12.5 H, WHILE FLORAL FORMATION DID NOT BEGIN UNTIL THE DAY-LENGTH DROPPED BELOW 14 H. PURPLE NUTSEDGE FORMED INFLORESCENCES EARLIER AND PRODUCTION CONTINUED THROUGHOUT THE REMAINDER OF THE STUDY, BUT TUBER FORMATION ACCELERATED AS DAY-LN DECR.

WEED SCIENCE 24 186-190 1976 EN 35 ART USA Y Y THE OCCURANCE, ABUNDANCE, AND NATURE OF WEED COMMUNITIES WERE REVIED IN RELATION TO MAN'S MANIPULATION OF THE NATURAL ENVIRONMENT. MANIPULATIONS OF THE ENVIRONMENT NECESSARY FOR AGRICULTURAL PRODUCTION HAVE FORCED SECONDARY SUCCESIONSL SPECIES. THAT MANY OF THESE SERAL SPECIES HAVE OPPORTUNISTIC GENOTYPES HAS LED TO THE DEVELOPMENT OF WEEDS. WEEDS CONFORM TO THE CONCEPTS OF ECOLOGICAL SUCCESSSION, BUT AGRICULTURAL ECOSYSSTEMS ARE VERY DYNAMIC WITH SUDDEN AND RECURRENT CHANGES. THE ACCELERATION OF SUCCESSIONAL PATTERNS HAS PROVIDED ENVIRONMENTS CONDUCIVE TO THE SELECTION OF COMPETITIVE GENOTYPES AMONG NUMEROUS WEEDS. SPECIALIZED BREEDING SYSTEMS PROVIDE RAPID RESRESPONSES TO CHANGING CONDITIONS. WEEDS INCREASE THE DIVERSITY OF AGRICULTURAL ECOSYSTEMS BY UTILIZING ENVIRONMENTAL POTENTIAL CONCENTRATED FOR CROP PRODUCTION. WEEDS HAVE BEEN THE SHADOW OF HISTORY IN THAT THEY HAVE MIRRORED MAN'S ACTIVITIES. THE INTRODUCTION OF WEED SPECIES TO NEW ENVIRONMENTS MAY BE ONE OF THE GREATEST MANIPULATIONS OF THE NATURAL ENVIRONMENT, THE TOTAL CONSEQUENCES OF WHICH WILL BE DETERMINED IN THE FUTURE.

J. 2 200-246 1942 EN ART ISRAEL Y Y AN ATTEMPT IS MADE TO CHARACTERIZE THE MOST COMMON SOIL VARIETIES OF PALESTINE BY GEOBOTANICAL DATA. THE SOILS OF PALESTINE RARELY EXHIBIT PROFILES WITH TRUELY GENETIC HORIZONS AS IN MORE TEMPORATE REGIONS. PARTICULARLY IN THE MEDITERRANEAN PART OF THE COUNTRY ALMOST ALL THE SOIL UNITS ARE STRONGLY INFLUENCED BY HUMAN INTERFERENCE. SOME 20 TYPES AND SUB-TYPES ARE ECOLOGICALLY RECOGNIZABLE UNDER THE HEADINGS (1) CALCAREOUS SOILS (NOTABLY TERRA ROSA); (2) BASALT SOILS; (3) SANDY AND SANDY CALCAREOUS SOILS, INCLUDING DESERT SANDS; (4) LOES AND LOES-LIKE SOILS; (5) ALUVIAL, IRRIGATED AND PEAT SOILS; (6) SALINE SOILS.
