Abstract (sommario):

Wool production and reproductive performance components of similar genotypes, brought from distinct production areas, were evaluated during five years trial at similar environments, such as, joining season and stocking rate on winter improved pasture. The least squares means revealed that the origin (breed) effect concentrated upon the Corriedale ewes wool production, whereas in Romney females it affected the reproductive performance. In the abscence of interaction between origin (breed) and year for most variables, it was assumed that the farm management procedures and/or selection criteria a

Abstract (sommario):

A spatial prepattern mechanism based on a biochemical reaction referred to as a reaction-diffusion (RD) system is able to account for many aspects of the initiation and development of primary wool follicles. The RD system can spontaneously produce spatial patterns in the distribution of its chemical components within the epidermis and epithelium. The first pattern produced in the epidermis by the chosen RD system is a spotted pattern which gives rise to the first generation of primary central follicles. Follicles initiate at the location of the spots, i.e. the localized regions where maxima ex

In an accompanying paper it was shown that a spatial prepattern mechanism based on a biochemical reaction referred to as a reaction-diffusion (RD) system is able to account for many aspects of the initiation and development of primary (P) wool follicles. In this paper the same RD system is applied to the initiation and development of original secondary (SO) follicles. Prepatterns are generated by solving the equations describing the reaction and diffusion of the chemical components of the RD system in early stage follicles. It is demonstrated that the prepattern mechanism can account for the l

ABSTRACT Sheep meat quality is influenced by a number of factors either intrinsic (species, breed, sex, and age) or extrinsic (nutrition, environment, and pre- and post-slaughter handling) to the animal. However, it is not known whether wool fibre color variations within the same breed can influence the instrumental and sensory characteristics of the meat. Thus, the objective of this study was to investigate the effect of the genetic group on the instrumental and sensory characteristics of meat of white and natural colored Corriedale lambs.

Abstract (sommario):

Negative genetic correlations result in sheep selected for fleece weight having reduced fatness and reproductive turnoff. Both of these characteristics depend mainly on energy metabolism, but the links between wool growth and energy metabolism are poorly defined. The present study examined aspects of energy metabolism (body composition, feed intake, and metabolic hormones) in Merino sheep with high or low estimated breeding values for clean fleece weight (CFW) or fibre diameter (FD). The groups were selected to have similar mean liveweights. High CFW sheep had a lower proportion of fat (P <

Abstract (sommario):

This paper reviews the rationale and approach to economic analysis of practices aimed at managing the genetic aspects of forests. Some forest genetics, like tree improvement, involve costs aimed at increasing wood production. Other "forest genetics" activities may be aimed at managing populations of both commercial and non-commercial values. Economic analysis is relevant to both categories but it can be misapplied and mis-interpreted. Good economic analysis should confront the notion of trade-offs head-on, whether assessing intensive silviculture or options to achieve the non-wood objectives s

Abstract (sommario):

Heartwood color is a complex trait that affects the economic and aesthetic value of the wood but is highly variable. How the color of the heartwood varies spatially and temporally is poorly understood. To illustrate how heartwood color varies within a tree, two opposite aspects of wood within the same tree, representing differential growth rate, were used to model the long-short axis system jointly. The color of the heartwood on the long and the short axis was considered to be two different traits. By jointly modeling the long and short axes, the correlation was examined between aspect (spatia

Abstract (sommario):

The balance between cell proliferation and differentiation into other cell types is crucial for meristem indeterminacy, and both growth aspects are under genetic control. The peptide-receptor signaling module regulates the activity of the cambial stem cells and the differentiation of their derivatives, along with cytokinins and auxin. We identified the genes encoding the signaling module CLE41-PXY and the regulator of vascular cambium division WOX4 and studied their expression during the period of cambial growth in the radial row: the conducting phloem/cambial zone and the differentiating xyle

Abstract (sommario):

Soil saturation index and its calculating are demonstrating multicollinear correlations between ecological-geochemical soil state and environmental circumstances. There are wood ecosystems on the research area with Phaeozem, Luvisol, Retisol and Fluvisol. We have also studied the buried soil. Their burials occurred as a result of natural processes (about 5000 BP) and as a result of human impact (about 1000 BP). Age of separate genetic horizons (from 360±50 to 1870±160 ВР) indicates soils genesis during the last stage of the Holocene – Subatlantic. In our opinion the dynamics of the climate dur

Abstract (sommario):

SummaryLotus pedunculatus was grown under high fertility conditions and its nutritive value was determined in a feeding trial with sheep at Palmerston North, New Zealand in 1989. The condensed tannins (CT) accounted for 5·5 % of lotus dry matter (DM) and its effect on digestion was evaluated by giving an intraruminal infusion of polyethylene glycol (PEG) to six of the sheep (PEG group). PEG preferentially binds with CT so that the lotus becomes essentially CT-free.The experiment was carried out with 14 sheep (six PEG and eight ‘Tannin’) held in metabolism crates indoors and given freshly cut l

Abstract (sommario):

Currently, the genus Populus is one of the favourite objects for research of molecular genetics of woody plants. A high growth rate and the broadly applicable timber as raw material for different types of products made of wood make poplar attractive for industrial usage. Despite the positive aspect of its growth capacity and wood composition, one major problem in cultivating fast-growing tree species in a forestry plantation system is the comparably high water demand of the plants. In this context, a rapid development of an efficient adventitious root system from dormant hardwood cuttings is a

SUMMARY It has been an assumption of many practitioners of comparative linguistics that genetic relations are defined between languages as holistic entities. A recent explicit expression of this position is Thomason &Kaufman (1988). An alternative viewpoint, probably a minority position, is that expressed (inter alia) by Allen (1953), which defines genetic relations in terms of linguistic components. Assuming the correctness of the first position, which is the more stringent one, I examine one aspect of linguistic structure in Nigerian Arabic, idiomatic expressions, showing that Nigerian A

Abstract To understand how variation in warning displays evolves and is maintained, we need to understand not only how perceivers of these traits select color and toxicity but also the sources of the genetic and phenotypic variation exposed to selection by them. We studied these aspects in the wood tiger moth Arctia plantaginis, which has two locally co-occurring male color morphs in Europe: yellow and white. When threatened, both morphs produce defensive secretions from their abdomen and from thoracic glands. Abdominal fluid has shown to be more important against invertebrate predators than a

Animal biography challenges both of these categories: what is a true dog character and how close can an author come to a life-like depiction of it?
