Abstract:

Isotope turnover rates of perenties, Varanus giganteus, were determined during two consecutive summers on Barrow I., W.A. The turnover rates were significantly lower in the first summer than those in the second, and there were considerable differences in turnover rates between individuals in both years. Estimated rates of prey consumption were 7.3 and 36.4 g kg- day-l , respectively, during the two summers, and perenties were more active during the second summer. The mean daily energy expenditure for a 10-kg perentie was much higher in both years than that predicted by allometric equations for

Abstract:

The daily activity pattern of the perentie Varanus giganteus on Barrow Island, was bimodal in summer with activity concentrated during the morning and late afternoon. Animais were active on most days in summer. Mean activity temperatures were approximately 36�C, which is similar to those of other varanid species. The heating rate for one animal was 0.09�C min-1. The activity areas of animals ranged in size from 2.9-21.5 ha. The diet consisted mainly of turtle eggs or hatchlings and other vertebrates. Mating and egg-laying appear to take place in the spring.

Abstract:

Abstract ContextEstimating animal abundance often relies on being able to identify individuals; however, this can be challenging, especially when applied to large animals that are difficult to trap and handle. Camera traps have provided a non-invasive alternative by using natural markings to individually identify animals within image data. Although camera traps have been used to individually identify mammals, they are yet to be widely applied to other taxa, such as reptiles. AimsWe assessed the capacity of camera traps to provide images that allow for individual identification of the world’s f

Abstract:

Understanding the behavioural responses of animals to habitat change is vital to their conservation in landscapes undergoing restoration. Studies of animal responses to habitat restoration typically assess species presence/absence; however, such studies may be restricted in their ability to show whether restoration is facilitating the return of self-sustaining and functional fauna populations. We present a case study using VHF/GPS tracking of a young adult perentie (Varanus giganteus), to demonstrate the range of applications of the Time Local Convex Hull method of home-range construction in a

An excursion was made into the history of the formation of this phenomenon, an overview of its directions, personalities and key concepts. The connection of traditionalism with idealistic philosophy, Romanticism, right-wing ideologies and academic religious studies is traced. The study concluded that integral traditionalism, as a special form of Western esotericism, is an organic part of European culture. Its place in the space of the latter can be represented i

Abstract:

The English daisy, Bellis perennis L., is a widespread lawn weed and a bane to those who favor daisy-free lawns and golf courses. The genetic name Bellis, a designation used by Pliny, means “pretty”; perennis means “through the years,” “continuing,” or “perennial” (Gledhill 1985; Mabberley 1989). While pretty, the English daisy is a persistent weed that spreads by short stolons (Tutin et al. 1976). It is a member of the cosmopolitan family Compositae, which encompasses 1,100 genera and 25,000 species (Heywood 1993). The genus Bellis comprises about 15 European and Mediterranean species. Some o

We examined the effects of a root-feeding beetle larva (Anomala cuprea Hope) on the survival and biomass of Lolium perenne L. and Plantago lanceolata L. plants at various ages. We hypothesized that belowground herbivory would kill more juveniles than mature plants because of greater root damage. We predicted that for juvenile plants, mortality would be higher for P. lanceolata than for L. perenne, because the thin taproot of P. lanceolata is less tolerant to herbivory. We hypothesized that for mature plants, herbivory of fibrous roots would negatively affect biomass; thus, L. perenne would be

Abstract A single chromosome of the grass species Festuca pratensis has been introgressed into Lolium perenne to produce a diploid monosomic substitution line (2n = 2x = 14). The chromatin of F. pratensis and L. perenne can be distinguished by genomic in situ hybridization (GISH), and it is therefore possible to visualize the substituted F. pratensis chromosome in the L. perenne background and to study chiasma formation in a single marked bivalent. Recombination occurs freely in the F. pratensis/L. perenne bivalent, and chiasma frequency counts give a predicted map length for this bivalent of

Abstract:

In order to understand better the factors which influence the persistence or non-persistence of Lolium perenne and Trifolium repens on damp hill land in a wet climate, swards in mid-Wales which had been converted from semi-natural rough grazing (predominantly Molinia caerulea or Nardus stricta or Agrostis/Festuca/Nardus) in 1961–81 were examined in 1982 and 1999, using a point quadrat technique.There was a marked decline between 1982 and 1999 in the proportion of L. perenne in the majority of the study areas. On the other hand, in 1999 the oldest swards (sown 30–38 years before) contained at l

Abstract:

A pot experiment on an acid brown soil was conducted in 1998-2001. Three multicomponent fertilizers were applied: Polifoska 8, Polifoska 15 and Polimag 306, Travit at the rates of 0.5; 1.0; and 1.5 gN per pot. The total forms of potassium were determined in dry matter of perennial ryegrass with the use of ASA method. The contents of these elements were higher in the fertilized variants as compared to the control. No significant differences were found among the contents of investigated elements compared in plants treated with different multicomponent fertilizers. The chemical analyses indicated

Abstract:

DM production and crop characteristics of Medicago sativa were studied in comparison with Lolium perenne and maize under temperate conditions and various N applications. Annual DM yields of M. sativa ranged from 13.4 to 18.1 t/ha and were comparable to those of L. perenne and maize. However, the digestibility of M. sativa was lower than that of L. perenne cut for silage and that of maize. Despite significant differences in leaf:stem ratio, specific leaf area and LAI, full light interception was achieved with the same amount of DM for L. perenne and M. sativa. After defoliation by cutting, the

Abstract:

Worldwide drought stress is the most important restriction factor on food and fodder productivity. In this study, morpho-physiological adaptations to dehydration stress were investigated in two tall fescue (Festuca arundinacea Schreb.) genotypes (Fa13 and Fa19 with a high and low sheep grazing preference respectively) and Lolium perenne L. Drought stress as evaluated by decreasing stomatal conductance and chlorophyll content, chlorophyll fluorescence parameters and fructan concentration were first observed in L. perenne (16 days after the start of the drought stress). Furthermore, after 20 day

Abstract:

The developmental cycle of <em>Mercurialis perennis</em> L. polycormones lasts about 6 years. Under natural conditions polycormones arise by way of vegetative propagation. Their development and growth depend on the age, size and developmental state of the part of the plant from which the new individual arises. Development of the polycormone is most intensive in the first three years. During that time the young individuals increase their number of above-ground and underground shoots according to geometrical progression. A certain stabilization in growth and spread was observed in th
