Abstract:
AbstractThe spatial distribution of the abundance indices of the deep-water rose shrimp Parapenaeus longirostris was investigated applying geostatistical techniques on data collected in the central southern Tyrrhenian Sea from bottom trawl surveys carried out in the autumn since 1994. Experimental variograms (auto and cross) were constructed on the variable "abundance index", expressed in kg/km2, and those variogram models best describing the spatial continuity were detected and validated by the jackknife technique. The spatial structure of the "abundance index", exhibiting a similar pattern t

Knowledge about dispersion is of utmost importance for understanding populations’ reaction to changes in the environment. Expansion of a population range brings with it both spatial sorting and over time, spatial selection. This means that dispersion rates increases over time at the expanding edge. Most studies have so far been performed on continuously expanding populations. This study aims to bring more knowledge about dispersal biology in dynamic systems.

Estuaries are naturally stressed systems with a high degree of variability in their physical-chemical characteristics. The natural gradient of salinity, linked with other gradients (e.g. sediment type and dynamics, oxygen availability, temperature and current speed) are well documented as important factors in determining temporal and spatial variations in meiofauna communities. Among the estuarine biological components, meiobenthic communities are good indicators of environmental conditions and therefore changes in their density, diversity, structure and functioning indicate important alterati

Many species have shown recent shifts in their distribution in response to environmental changes, in particular to climate change, mostly moving towards higher latitudes and/or altitudes. In this framework, it’s crucial to determine temporal variation in species occurrence or abundance along altitudinal gradients in order to detect changes in altitudinal shifts and to assess sensitivity of mountain species to land use and climate change. The main purpose of the research was to detect temporal changes in species distribution along altitudinal gradients in the Alps at different levels of ecolog

Рост и развитие животных играют важную роль в производстве, селекции и их адаптации к окружающей среде в изменяющихся климатических условиях [1]. Поиск локусов количественных признаков (QTL) — это один из методов, который предоставляет возможность понять генетическую архитектуру признаков и выявить области генома, контролирующие количественные вариации признаков [2]. Селекция с помощью молекулярных маркеров – один из способов повышения мясной продуктивности сельскохозяйственной птицы.

Abstract:
Metrology approach to the personality traits is proposed, similar to the measurement of physical quantities of the International System of Units (SI). The analysis was made of open database of 500 subjects test including psychophysiological responses (PPR) to 48 multifactorial stimuli tied to multiple intelligences and personality vices consistently presented by Blitz Judgment program. Various equations for calculating of the current psychophysiological state (PPS) and PPR according to microvibration data of a human head, measured by vibraimage technology, are considered.

Abstract:
The main goals of this project as stated in the original proposal were to identify which of the candidate gene(s) identified in a 1.5 Mb region of wheat and rye chromosomes 1RS and 1BS were responsible for the differences in root architecture, reveal their natural variation and characterize the epistatic interactions that modulate their effect in different backgrounds. Background: Wheat is an essential crop for global food security and is well adapted to a wide variety of soils. However, the gene networks regulating different wheat root architectures remain poorly understood. Root depth and bi

Abstract:
Research problem: Bread wheat (Triticumaestivum) provides approximately 20% of the calories and proteins consumed by humankind. As the world population continues to increase, it is necessary to improve wheat yields, increase grain quality, and minimize the losses produced by biotic and abiotic stresses. Stripe rust, caused by Pucciniastriiformisf. sp. tritici(Pst), is one of the most destructive diseases of wheat. The new pathogen races are more virulent and aggressive than previous ones and have produced large economic losses. A rich source for stripe-rust resistance genes (Yr) was found in w

Abstract:
Architecture of a root system is the expression of the potential of various root types to branch, to grow and to coordinate with other plant organs, under the specific limitations of the environmental conditions. The present investigation has proven the following points. 1) Genotypes with different types of root systems were identified. The growth patterns of their roots and the distribution of laterals along their main axes were recorded. 2) The patterns of development of the root systems of four cotton genotypes, throughout the entire life cycle of the plants, were described, even at such a

Abstract:
Meiotic recombination is a process in which homologous chromosomes engage in the exchange of DNA segments, creating gametes with new genetic makeup and progeny with new traits. The genetic diversity generated in this way is the main engine of crop improvement in sexually reproducing plants. Understanding regulation of this process, particularly the regulation of the rate and location of recombination events, and devising ways of modifying them, was the major motivation of this project. The project was carried out in maize and wheat, two leading crops, in which any advance in the breeder’s tool

Abstract:
Control of agro-associated pathogens is becoming increasingly difficult due to increased resistance and mounting restrictions on chemical pesticides and antibiotics. Likewise, in veterinary and human environments, there is increasing resistance of pathogens to currently available antibiotics requiring discovery of novel antibiotic compounds. These drawbacks necessitate discovery and application of microorganisms that can be used as biocontrol agents (BCAs) and the isolation of novel biologically-active compounds. This highly-synergistic one year project implemented an innovative pipeline aimed

Abstract:
Fifty six diverse spring wheat cultivars were evaluated for genetic variation and heritability for thermotolerance in terms of cell-membrane stability (CMS) and triphenyl tetrazolium chloride (TTC) reduction. The most divergent cultivars for thermotolerance (Danbata-tolerant and Nacozari-susceptible) were crossed to develop an F8 random onbred line (RIL) population. This population was evaluated for co-segragation in CMS, yield under heat stress and HSP accumulation. Further studies of thermotolerance in relations to HSP and the expression of heterosis for growth under heat stress were perform

Abstract:
The objectives that were outlined in our original proposal have largely been achieved or will be so by the end of the project in February 1995 with one exception; that of mapping cold tolerance loci based on the segregation of tolerance in the BC1 progeny population. Briefly, our goals were to 1) construct a densely populated linkage map of the citrus genome: 2) map loci important in cold and/or salt stress tolerance; and 3) characterize the expression of genes responsive to cold land salt stress.
