Abstract:

A description is given of the abiotic and biotic factors that affect edaphic springtail distribution and the main role that collembola play in soil development. Collembola degrade organic matter that has been inoculated with microorganisms, which they control and disperse. They also help decompose recalcitrant molecules in ecosystems, release nitrogen, phosphorus and other elements into soils, and control phytopathogenic fungi in crops, as well as stimulate microbial respiration and serve as soil quality bioindicators. Water is the main factor that determines whether springtail populations are present, followed by temperature, which in turn controls whether new generations will occur. Enzyme metabolism and even DNA structure is affected by pH. Collembola populations are also affected by materials that enter the soil, including the leaf litter dropped by plant coverage, manures and soil fertilizers, and are regulated by the ascending forces in an ecosystem.

Abstract:

This paper reviews briefly the climatic and edaphic factors related to tree adaptation. Photoperiod regimens, the timing and severity of low temperatures, and high temperaturemoisture interactions all are important climatic determinants of adaptation for which adequate data have been widely recorded. Edaphic factors that injure trees in managed environments are more difficult to extrapolate to natural systems, but natural soils that are poorly drained, calcareous, alkaline, or saline may be initial foci for seeking tough trees. A project to identify promising new landscape plants for the north-central United States, by examining climatic, edaphic, and floristic factors in Eastern Europe, is presented as a case study.

Abstract:

Knowledge of the influence of environmental factors on weed populations is important in developing sustainable turfgrass management practices. Studies were conducted to evaluate the relationship of green and false-green kyllinga population densities with elevation and edaphic factors in turfgrass systems. Studies were conducted on five different golf courses in North Carolina, three affected by green kyllinga, and two affected by false-green kyllinga. According to Spearman correlation coefficients, both green and false-green kyllinga were correlated with increasing soil volumetric water content, whereas correlation of other edaphic variables varied among sites and species. Stepwise logistic regression confirmed the correlation of volumetric water with green kyllinga presence, but model components varied among sites for false-green kyllinga. Increasing green kyllinga populations correlated with increasing soil sodium; however, sodium did not reach a level believed to be detrimental to turfgrass growth. No other variables correlated with green or false-green kyllinga across all sites. We hypothesized that the lack of significant correlations was due to the overall influence of relative elevation on edaphic variables. According to principal components analysis (PCA), relative elevation had a profound impact on the measured edaphic variables at all sites. However, results of PCA at one site differed sharply from other sites. Results from that site demonstrate the potentially strong effects of management practices to alter edaphic trends normally observed with topography.

Abstract:

Abstract: Plant-parasitic nematodes may cause mechanical damage to the roots, stems, leaves, and flower structures of many plants. The host plant is more important in the nematode population. The control of these nematodes is more difficult than that of other pests because they mostly inhabit the inner part of the crops. Some Edaphic factors and secondary metabolites of plants play an important role in nematode control. The present study aims to analyze the comparision between agriculture soil and common land soil in relation to soil edaphic factors and nematode community. For testing nematode infection in crops, different agricultural fields were selected from different areas in and around Junagadh District. We have selected some agriculture sites in which nematode population were widely found. On the other hand, common land soil were no nematode population found. Edaphic factors like soil pH, Temperature, Moisture, Organic Carbon, Electrical Conductivity, Phosphorus, and Potassium were effective in the nematode growth. Results indicate that Soil temperature and Moisture were more affected in the nematode community. Further studies for the control of these nematodes are underway.

Abstract:

Forest nitrous oxide (N2O) emission plays an important role in the greenhouse gas budget of forest ecosystems. However, spatial variability in N2O fluxes complicates the determination of key factors of N2O fluxes at different scales. Based on an updated database of N2O fluxes and the main edaphic factors of global forests, the magnitude of N2O fluxes from forests and the relationships between edaphic factors and N2O fluxes at different scales were analyzed. According to the results, the average annual N2O flux of the global forest was 142.91 ± 14.1 mg N m−2 year−1. The range of total forest estimated N2O emission was 4.45–4.69 Tg N in 2000. N2O fluxes from forests with different leaf traits (broadleaved and coniferous) have significant differences in magnitude, whereas the leaf habit (evergreen and deciduous) was an important characteristic reflecting different patterns of N2O seasonal variations. The main factors affecting N2O fluxes on the global scale were ammonium (NH4+) and nitrate (NO3−) concentrations. With an increasing scale (from the site scale to the regional scale to the global scale), the explanatory power of the five edaphic factors to N2O flux decreased gradually. In addition, the response curves of N2O flux to edaphic factors were diversified among different scales. At both the global and regional scales, soil hydrothermal condition (water filled pore space (WFPS) and soil temperature) might not be the main spatial regulation for N2O fluxes, whereas soil nutrient factors (particularly NO3− concentration) could contribute more on N2O flux spatial variations. The results of site-control analysis demonstrated that there were high spatial heterogeneity of the main N2O controls, showing N2O fluxes from low latitude forests being more likely associated with soil WFPS and temperature. Thus, our findings provide valuable insights into the regulatory edaphic factors underlying the variability in N2O emissions, when modeling at different scales.

Abstract:

The influence of soil characteristics on the lability and bioavailability of zinc at both background and phytotoxic concentrations in Albic Retisol soil (Loamic, Ochric) was studied using various methods. Ranges of insufficient, non-phytotoxic, and phytotoxic zinc concentrations in soil solutions were established in an experiment with an aqueous barley culture. It was experimentally revealed that for a wide range of non-toxic concentrations of Zn in the soil corresponding to the indicative type of plant response, there was constancy of the concentration ratio (CR) and concentration factor (CF) migration parameters. As a result, a new method for assessing the buffer capacity of soils with respect to Zn (PBCZn) is proposed. The transformation processes of the chemical forms and root uptake of native (natural) zinc contained in the Albic Retisol (Loamic, Ochric) through the aqueous culture of barley were studied using a cyclic lysimetric installation and radioactive 65Zn tracer. The distribution patterns of Zn(65Zn) between different forms (chemical fractions) in the soil were established using the sequential fractionation scheme of BCR. The coefficients of distribution and concentration factors of natural Zn and 65Zn, as well as accumulation and removal of the metal by plants were estimated. The values of the enrichment factor of natural (stable) Zn contained in sequentially extracted chemical fractions with the 65Zn radioisotope were determined and the amount of the pool of labile zinc compounds in the studied soil was calculated.

Sofiah S, Setiadi D, Widyatmoko D. 2018. The Influence of Edaphic Factors on Bamboo Population in Mount Baung Natural Tourist Park, Pasuruan, East Java. Trop Drylands 2: 12-17. There are 1250 bamboo species in the world, an estimated 161 of them are in Indonesia. Mount Baung Natural Tourist Park (MBNTP) is one of the bamboo forests located in a conservation area in East Java. The purpose of this research was to study the influence of edaphic factors on the growth of bamboo. This research was carried out from September 2011 to May 2012. The principal component analysis (PCA) was performed to determine the relationships between edaphic components and bamboo occurrences. Seven species of bamboo were found in MBNTP, namely, Bambusa blumeana, Bambusa vulgaris, Dendrocalamus asper, Schizostachyum iraten, Gigantochloa atter, Gigantochloa apus, and Dinochloa matmat. The edaphic factors affected the presence of bamboo in MBNTP. Phosphor (P) is one of the edaphic factors which contributes significantly to B. blumeana, B. vulgaris, D. asper and S. iraten presence in MBNTP. These bamboos grow in soil with high P levels of up to 27 ppm. The existence of G. apus was influenced by Manganese (Mn) and Sodium (Na) elements. This bamboo in this area was more commonly found in soil environments with low levels of Na (< 0.02 (cmol (+) kg-1)) and Mn (≤ 24 ppm). The species of bamboo with the densest population in Mount Baung, namely B. blumeana, was influenced by environment factor, i.e., the slope. Each bamboo has its own uniqueness in its growth. G. apus and G. atter populations were affected by solar radiation.

Abstract:

Glomalin-related soil protein (GRSP), soil nutrients, and soil enzyme activities are closely related to soil fertility and land productivity, which play an important role in indicating soil quality. Little is known about the spatial variation in GRSP and its relationship with edaphic factors. Here, the spatial distribution of GRSP, soil chemical properties, and the soil enzyme activities of 0–20 cm depth farmland soil in the black soil region of northeast China were investigated, and the relationships among edaphic factors were analyzed collected from 41 sampling sites. The results indicate that GRSP, soil organic matter, total nitrogen, and acid phosphatase activities showed significant patterns of spatial variation, generally decreasing from north to south along a latitudinal gradient. Principal component analysis revealed that total GRSP (by 80.19%) and soil organic matter content (by 80.15%) were the greatest contributing factors accounting for the variations. Edaphic factors such as soil organic matter, total nitrogen, total phosphorus, and acid phosphatase were significantly positively correlated with GRSP, while urease was negatively correlated with GRSP. Mantel tests also showed that soil organic matter, total nitrogen, urease, and acid phosphatase were positively correlated with GRSP. The results reflect the soil fertility characteristics of the black soil region of northeast China and reveal the relationship among edaphic factors. These findings could be used to inform agricultural production and provide new insight into the role of GRSP in soil quality.

Abstract:

Abstract This paper examines the role of ecological factors, derived from principal component analysis performed on edaphic and vegetational dataset as well as spatial variables, in structuring the soil macrofauna community of the Dnipro floodplain within the ‘Dnipro-Orilsky’ Nature Reserve (Ukraine). The soil macrofauna was defined as invertebrates visible to the naked eye (macroscopic organisms). The test points formed a regular grid with a mesh size of 3 m with 7 × 15 dimensions. Thus, the total test point number was 105. At each point, soil-zoological samples of 0.25 × 0.25 m were taken for quantifying the soil macrofauna. The spatial structure was modeled by a set of independent spatial patterns obtained by means of principal coordinates of neighbor matrices analysis (PCNM-variables). Spatial PCNM-variables explain significantly more variations of the community (19.9%) than edaphic factors (4.1%) and vegetation factors (3.2%). Spatial and combined environmental and spatial effects were divided into three components: broad-scale component was characterized by periodicity of spatial variation with a wavelength of 24.0–44.5 m, medium-scale – 11.1–20 m, fine-scale – 6.6–11.0 m. For a broad-scale component, environmental factors of a vegetational nature are more important, for medium-scale, edaphic factors are more important, for fine-scale, both vegetation and edaphic are important. For litter-dwelling animals, the most characteristic spatial patterns are on the broad and medium-scale levels. For endogeic and anecic animals, the most significant variability is on the fine-scale level.

Abstract:

Edaphic gradients can explain plant species distribution at a local scale in the neotropics and elsewhere, but few studies have evaluated the individual responses of species to such gradients. We collected data on species and soils in open savannic and forest formations (totalling five habitats in each formation), aiming to evaluate the importance of edaphic factors on the distribution of woody plant species in tropical habitats. Logistic regression was used to test the influence of predictor variables (soil texture and fertility) on plant occurrence (presence or absence). Most species (73%) responded to the edaphic gradients. However, the edaphic gradients did not explain the distribution of the remaining 27% of species, which implies the existence of other factors determining their occurrence. Soil fertility (nutritional status) was the major factor in forest habitats (65% of the species which showed significant response), while soil texture was the most explanatory factor for species occurrence in open habitats (55% of the species that showed a significant response). Thus, nutrient status was less limiting and soil texture was more limiting in savannic formations, whereas the opposite was observed for forest formations. Most species showing a relationship with edaphic gradients had a unimodal response, which is in accordance with the literature. Our study showed that soil properties largely regulate the distribution of plant species in tropical habitats, despite other factors not investigated here also having an effect on several of the studied species. Models of species distribution that take into account environmental heterogeneity are key for the elaboration of strategies for the conservation and restoration of ecosystems.

Abstract:

AbstractThe article presents the results of evaluation of the role of edaphic and vegetation factors on beta diversity of soil macrofauna by means of the MDM-approach. The multinomial diversity model (MDM) is a method for relating the Shannon diversity to ecological factors. The research was conducted in the ‘Dnipro-Orils’kiy’ Nature Reserve (Ukraine). The research polygon was laid in the forest within the Orlova ravine (48º31’13 “N, 34º48”15 “E). The study site comprises 1.0 ha of deciduous woodland bordered by an area of herbaceous cover within the ravine. In the soil of the studied polygon, 38 species of soil invertebrates were identified, which characterizes the gamma diversity. Alpha diversity, or the number of species on average at each sample point is 4.3. Beta diversity is 8.8. The principal component analysis of the edaphic parameters revealed four statistically significant principal components. For vegetation characteristics, six statistically significant principal components were identified. The sequential analysis of the effects shows that edaphic factors accounted for 20.9% (0.81 bit) of the available entropy (1.71–0.91). The largest decrease in the community entropy takes place under the action of the principal components 2 and 3 (0.06 bit and 0.05, respectively). A permutation test showed that these effects are statistically significant. In turn, 28.4% of the community β-diversity is attributable to vegetation factors. The greatest decrease in community entropy is related to the principal vegetation components 1, 3 and 4 (0.07, 0.05 and 0.04 bits, respectively). A permutation test indicated that this effect is statistically reliable. Geostatistical models substantially describe the varying effects on the beta-diversity of edaphic principal components 1 and 2, and the vegetation principal components 1 and 3. It was found that edaphic and plant factors play an important role in structuring the communities of soil macrofauna on the level of beta diversity. Community sensitivity to environmental factors varies in space and is spatially structured. For different environmental factors, specific spatial patterns of community sensitivity are allocated. Beta diversity may be due to the fact that the species of soil macrofauna communities also vary in the degree of sensitivity to various environmental factors. The species of soil microfauna are also divided according to their extent of sensitivity to different ecological factors.

Abstract:

Weeds are important components of the agroecosystems due to their role as primary producers within the farming systems, yet they are considered as major constraints to crop production. A phytosociological study was conducted to assess the composition and spatial distribution of existing weed species under the influence of various edaphic factors in the 15 wheat fields. Quadrat method was applied and different phytosociological attributes including abundance, density, and frequency were estimated by randomly laying down 10 square-shaped quadrats of size 1m2 in each wheat field. A total of 34 weed species belonging to 17 families and 30 genera were explored from 150 quadrats. Fabaceae and Asteraceae were ubiquitous plant families. Various edaphic factors such as; soil texture, electrical conductivity, soil pH, total dissolved solids, nitrogen, calcium carbonate, organic matter, NaCl, calcium, phosphorous, potassium, sodium, and zinc were determined. Pearson’s correlation was employed to correlate weeds and the potential edaphic variables. The results depicted that most of these weed pairs’ associations correlated positively. Simultaneously, the abundant weed species including Trifolium repens, Coronopus didymus, and Urtica dioica showed a positive correlation with most of the investigated ecological variables.

Abstract:

SUMMARYManaged grasslands provide environmental and agronomic services that can be predicted from the botanical and functional composition of the vegetation. These are influenced by management, edaphic and climatic factors. The present report set out to estimate and analyse the relative importance of management, soil and climate factors on botanical and functional characteristics of grassland vegetation. A set of 178 French grasslands having a large pedoclimatic and management gradient was selected, and information collected on botanical composition, pedoclimatic factors and management. Six vegetation characteristics were considered: two botanical (floristic composition and species dominance) and four functional (proportion of entomophilous species, number of oligotrophic species, leaf dry matter content and date of flowering). First, the links between the characteristics of the vegetation were analysed to check for any redundancy among them; all were kept. Second, it was demonstrated that botanical and functional characteristics were not driven by the same factors: functional composition was characterized by management, edaphic and climatic factors, whereas botanical composition was influenced mainly by climatic and edaphic factors plus other factors. Interactions between factors also have to be taken into consideration to predict botanical and functional composition of grasslands. Functional and botanical characteristics of vegetation help to predict ecosystem services delivered by grasslands and may be used in combination.

Issues of phytoindication and phytomonitoring of major ecological factors for large-scale regional (zonal) investigations are analyzed. The presented methodical approaches of phytoindication and examples of their application show the prospects of this scientific direction for the regional (zonal) ecological monitoring of edaphic regimes in forest ecotopes. The subjects of research were the first level monitoring plots (146 plots) located within Dnipro Left Bank Forest-Steppe forestry district, Ukraine. A concept of “eco-background”, i. e. the background factors of forests (a range of values within the limits of standard deviations), in relation to which the direction and intensity of edaphic and climatic processes are measured in the forest ecotopes of specific region, and within the region, in the ecotopes of the coniferous, mixed and broad-leaved forests, is used for the comparative monitoring of fluctuations and dynamics of the ecological regimes in relation to typical and zonally-provided values in the forest ecotopes of the region. The total edaphic eco-background (including hydro-background, acido-background, total salt-background, carbonate content-background, nitro-background) was investigated for the district’s forests and within the district, the separate edaphic eco-backgrounds of coniferous, mixed and broad-leaved forests.

Abstract:

Introduction – Edaphic factors influence the structure and composition of plant communities. The main objective is to identify soil properties associated with the presence of different Limonium species. Methods – We conducted a systematic phytocoenological and edaphic survey over 37 locations across the Balearic archipelago. Canonical Correspondence Analysis was applied to the physicochemical characteristics of soils in which 29 species of Limonium grow. Results – The distribution of Limonium species has a high correlation to specific edaphic factors. The species can be clustered into four major groups. The first group represents species with a high edaphic selectivity – soils characterized by having a high proportion of sand, SO42- and Ca2+. The second group is composed of species with high levels of SAR, OM and SO42- /Cl- ratio. The third group includes species present in soils with a loamy texture, low Ca2+ /Mg2+ ratio and high levels of CO32- and Mg2+. The fourth group includes plants which colonize soils that have a sandy texture, low salinity and high proportion of CO32-. Conclusions – A strong correlation between the distribution of Limonium species and soil characteristics exist. The study contributes to the establishment of foundations for habitat conservation, cultivation and recovery projects for endangered species of Limonium.

Abstract:

Horizontal (east, centre, west) and vertical (bottom, middle and top) distribution study of plants as well as the study of edaphic factors were done in 2016 in Chameli Community Forest hill. Soil samples were taken from bottom, middle and top areas of east, centre and west reasons of the hill. During this study, Schima wallichi and Rhododendron arboreum were found dominant species and had less effect of edaphic factors. Similarly climber plants like Smilax aspara, Smilax lancaefolia, Smilax ovalifolia and Dioscorea bulbifera were absent in west area of top region which might be due to low content of moisture, pH, and phosphorous. Scutellaria repens, Sida cordifolia, Solanum nigrum, Tripterospermum volubile, Carex baccans, Heteropogan contortus etc. were absent in west areas of middle region which might be due to the effect of high % of sand, phosphorous and moisture content and has low % of silt, potassium and pH. Herbs are more dominant in bottom, trees in middle and shrubs in top region. The east area of bottom, middle and top region had more diverse vegetation. The average of organic matter percentage, nitrogen, potassium and phosphorous content was maximum in middle hill which supports the highly diversified tree species and dense forest. Phosphorous showed the most effective factor on plant distribution. Therefore, for the proper growth, functioning and abundance of plant species, edaphic factors had a significant effect and play an important role on plant distribution.Int. J. Appl. Sci. Biotechnol.

Abstract:

The objective of this work was to describe the spatial distribution pattern of the arboreal and regenerating forest stratum and its relationship with edaphic factors in a multistratified agroforestry system without management. The data were obtained by means of a census of the arboreal and regenerating plants, in which the variables diameter were measured at 1.30m of the soil and total height, besides the botanical identification. The plants of the arboreal stratum were grouped in diameter and height classes and the regenerating plants in height classes. In both strata, the horizontal structure indicators were estimated and the species of higher Importance Value Index (IVI) were selected to perform the spatial analysis. The K Ripley function was applied in the univariate case to test the hypothesis of complete randomness in the groups and in the arboreal and regenerating species of higher IVI. In the bivariate case, the Ripley K function was applied to test the hypothesis of complete spatial independence between groups or aggregate pattern species, with edaphic attributes. The results indicated random spatial pattern for most of the tested groups, with only the species Gliricidia sepium and Archontophoenix alexandrae with aggregate spatial pattern, up to 30m distance, in the arboreal and regenerating strata, respectively. However, no spatial relationship was observed between the pattern of distribution of the species and the soil factors of agroforestry system (SAF). In general, it is concluded that edaphic factors were fundamental in the development of plants, but not for the formation of aggregates

Abstract:

Characteristics of vineyard soils and management practices can be assessed to determine the soil trend evolution, risks, and limits of soils for vine production through soil factors and foliar diagnosis. This study was made with soils from a vineyard divided into two plots belonging to the Rías Baixas D.O. The vineyard soils were sampled and characterized for three years. The total and available Cu and Zn contents and the physicochemical characteristics of the soils were determined annually and every four months, respectively. The main objective was to assess edaphic properties, phytosanitary treatments, fertilization, and tillage applied to indicate the quality of the vineyard soils. The soils presented certain limitations associated with mechanization, trafficability, and ease of tillage for cultivation. The soils showed a sandy loam texture, which makes the application of compost necessary to improve water retention and cation exchange capacity. Phytosanitary treatments and fungicides caused phytotoxic contents of Cu and Zn in the soils without being detrimental to the vines. In conclusion, the edaphic factors and foliar analysis were adequate to evaluate the condition of the soils and vines and to establish the necessary measures to improve the edaphic conditions of the vineyard soils to improve plant production.

Abstract:

Edaphic properties have been widely shown to influence community composition and distribution. However, the degree to which edaphic factors can affect grasses in semi-arid lowlands is still little researched. We assessed the significance of nine edaphic factors to explain the distributions of 65 grass species with various ecological traits (i.e., the ecological indicator values for their preferred habitat) in the semi-arid lowlands of Pakistan. To record information on species composition and related ecological conditions, we selected 10 random sampling locations between 2020 and 2021. For each species, we determined the important value index (IVI) and looked at the primary indicator species that were identified using the indicator species analysis approach. The major genera were Setaria, Brachiaria, and Cenchrus with 6.15% species in each followed by Aristida, Panicum, and Eragrostis with 4.61% wild grass species, Bothriochloa, Bromus, Phragmites, Polypogon, Saccharum, Poa, Echinochloa, and Dactyloctenium with 3.07% species, whereas other genera had a single species each. In total, 80% of the species were native, while only 20% were introduced species. Microphylls accounted for 49.23% of the leaf size spectra of the grass flora in the study area. The other frequent traits included macrophylls (21.53%), nanophylls (20%), and leptophylls (9.23%). The major life forms were therophytes (56.92%) followed by hemicryptophytes (38.46%) and geophytes (4.61%). The results of an ordination analysis indicated that the distribution of grasses was significantly (p ≤ 0.002) influenced by several edaphic parameters, with pH having the greatest impact on species distribution. The analyses of indicator species showed that pH and EC were the most powerful and important edaphic factors for determining the composition of plant communities and indicator species. The significant indicator species in various ecosystems were Cynodon dactylon (L.) Pers. rainer.bussmann@smnk.de and Leptochloa chinensis (L.) Nees (agroecosystem), Brachiaria reptans (L.) C.A. Gardner and C.E. Hubb, Dichanthium annulatum (Forssk.) Stapf, and Saccharum spontaneum L. (forest ecosystem), Cenchrus biflorus Roxb., Cenchrus ciliaris L., and Desmostachya bipinnata (L.) Stapf (urban ecosystem), Arundo donax L., Echinochloa crus-galli, and Phragmites australis (wetland ecosystem), and Saccharum spontaneum and Echinochloa crus-galli (L.) P. Beauv. (riparian ecosystem). We discovered that different species groupings had different habitat preferences and that soil pH had a significant beneficial effect on plant variety. These results provide a scientific roadmap for soil and plant restoration in semi-arid lowland habitats.

Abstract:

The quick-frozen (QF) cut and peel processing industry is growing and has significant economical importance. Crack development formation (CDF) and enhancement is a major obstacle in QF carrot processing since it lowers product quality, profitability and consumer preference. Studies were initiated to determine the role of edaphic factors on crack development. Carrot samples (var. Sugarsnax) were collected from nine different fields before processing, after processing, and after 8 weeks of -8 °C freezer storage. Samples were tested for the percent cracked; the length, width, and depth of cracks; and membrane stability using electrical conductivity per gram (EC/g). Membrane injury index (MII) was also analyzed on freezer-stored samples. Very few cracks and low EC readings were observed in treatments prior to processing, with the exception of field VC38. Samples taken at the end of the processing line had a higher percentage of visual cracks and significant differences were found between fields in EC/g and length, but not in width or depth of cracks. Freezer-stored samples had significant differences in all parameters, including EC/g, MII, crack length, width, and depth, indicating that the length of freezer storage time can increase the potential for crack development. Samples from V49 cracked heavily during 8 weeks in freezer storage compared to the samples from other fields. A significant interaction between field and time was also observed in processed samples, indicating that CDF is dependent on both field parameters and freezer storage time. Significant differences were observed among different fields in terms of crack morphology, especially after 8 weeks in freezer storage.

Abstract:

The results of the primary productivity investigation of agrobiogeocoenoses in different edaphic condition of reclamated soil have been presented. The spatial variability of the plant community biomass has been shown by means of GIS-approaches. By means of regression analysis the dependence of the phytomass on edaphic factors, such as aggregate composition and humus content, have been quantitatively assessed. The data obtained reveal that the rise of the soil aggregate with size of more than 3 mm leads to primary production increase of agrobiogeocenoses in the recultivated areas.

Abstract:

Sugarcane (Saccharum officinarum L.) grows under different weather conditions directly affecting crop maturation. Raw material quality predicting models are important tools in sugarcane crop management; the goal of these models is to provide productivity estimates during harvesting, increasing the efficiency of strategical and administrative decisions. The objective of this work was developing a model to predict Total Recoverable Sugars (TRS) during harvesting, using data related to production factors such as soil water storage and negative degree-days. The database of a sugar mill for the crop seasons 1999/2000, 2000/2001 and 2001/2002 was analyzed, and statistical models were tested to estimate raw material. The maturity model for a one-year old sugarcane proved to be significant, with a coefficient of determination (R²) of 0.7049*. No differences were detected between measured and estimated data in the simulation (P < 0.05).

Abstract:

Archaea are ubiquitous and highly abundant in Arctic soils. Because of their oligotrophic nature, archaea play an important role in biogeochemical processes in nutrient-limited Arctic soils. With the existing knowledge of high archaeal abundance and functional potential in Arctic soils, this study employed terminal restriction fragment length polymorphism (t-RFLP) profiling and geostatistical analysis to explore spatial dependency and edaphic determinants of the overall archaeal (ARC) and ammonia-oxidizing archaeal (AOA) communities in a high Arctic polar oasis soil. ARC communities were spatially dependent at the 2–5 m scale (P < 0.05), whereas AOA communities were dependent at the ∼1 m scale (P < 0.0001). Soil moisture, pH, and total carbon content were key edaphic factors driving both the ARC and AOA community structure. However, AOA evenness had simultaneous correlations with dissolved organic nitrogen and mineral nitrogen, indicating a possible niche differentiation for AOA in which dry mineral and wet organic soil microsites support different AOA genotypes. Richness, evenness, and diversity indices of both ARC and AOA communities showed high spatial dependency along the landscape and resembled scaling of edaphic factors. The spatial link between archaeal community structure and soil resources found in this study has implications for predictive understanding of archaea-driven processes in polar oases.

Abstract:

Arbuscular mycorrhizal fungi (AMF) colonization and spore numbers in the rhizosphere of two fruit species, Paullinia cupana Mart. and Theobroma grandiflorum Schum., growing in a terra firme ecosystem in Central Amazonia were studied from August 1998 to May 2000. Climatic and edaphic factors were also determined to investigate their influence on mycorrhizal variables. Soil pH, Al, Mn and effective cation exchange capacity exhibited seasonal variations during the investigation period. Temporal variations in mycorrhizal colonization levels and spore numbers occurred, indicating seasonality. Moreover, the patterns of mycorrhizal colonization levels and spore numbers for both host species were similar during the studied period. Mycorrhizal variables were related to climatic and edaphic factors, however, the intensity and type of influence of climatic and soil characteristics on AMF development tended to vary with the season and host plant species in Central Amazonia conditions.

Abstract:

SynopsisAn unusual form of Asplenium adiantum-nigrum from Scottish and European serpentine sites has been grown for several years under uniform conditions of culture alongside A. adiantum-nigrum of nonserpentine origin, and has been found to retain its characteristic features. The morphological distinctiveness of both types, apparent in juvenile as well as adult plants, has been maintained through successive generations.Transplant experiments were carried out in order to determine whether serpentine and non-serpentine plants differed also in their physiological response to soil factors. The results suggest that serpentine soils are unfavourable to the growth of non-serpentine A. adiantum-nigrum, particularly at germination and during the early development of the sporophyte. Soil analysis data are presented and briefly discussed.The experimental evidence presented here, combined with the constancy of the diagnostic differences leading to ease of recognition of the serpentine forms at all ages, suggests that evolution leading to the establishment of ecologically adapted divergent strains is actively in progress.
