Mouthpart and foregut ontogeny in phyllosoma larvae of the spiny lobster Jasus edwardsii (Decapoda: Palinuridae)

Mouthpart and foregut structure indicates that Jasus edwardsii phyllosomas ingest soft fleshy foods such as gelatinous zooplankton. Mouthpart morphology changes little during larval development, indicating that ingestive capabilities and external mastication are well developed from an early age. However, the density and complexity of setation and robustness of individual mouthparts increases with age, suggesting a greater capacity to ingest larger prey during development. The foregut consists of a single chamber with a number of well-developed grooves, ridges, and setae but lacking a gastric mill. The primary role of the foregut is mixing, sorting, and filtering particles, preground by the mouthparts. Phyllosomas have been divided into early (stage I-III), mid (IV-V), and late (VI-X) stages based on the development of the filter press and main brushes. Increasing robustness of setation and complexity of the foregut suggest that the texture of prey becomes more muscular (fibrous) with larval development. The results presented here suggest that early-stage phyllosoma would benefit from a diet comprising soft gelatinous items, whereas late-stage phyllosomas are better prepared to deal with larger, fleshy prey. The changes in structural characteristics with age should also serve as a guide in the development of formulated diets.
Comparison of Glyphosate with Other Herbicides for Weed Control in Corn (Zea mays): Efficacy and Economics1

Abstract: Glyphosate was compared with other commonly used corn herbicides at three locations in Kentucky in 1998 and 1999. Sequential glyphosate treatments provided greater than 87% control of common cocklebur, ivyleaf morningglory, common lambsquarters, and giant ragweed. Control of these species with glyphosate treatments was similar to the control with atrazine plus other postemergence (POST) herbicides. Generally, treatments containing s-triazines and chloracetamides applied to the soil surface were not as effective as sequential glyphosate or atrazine plus POST herbicides. Corn yield was not significantly different at any location or for any year, whereas differences in net return occurred at one location in 1998.

Comparisons Of Laboratory And Feral Strains Of Spodoptera frugiperda And Helicoverpa zea (Lepidoptera: Noctuidae) In Laboratory And Field Bioassays

The effects of resistant corn entries and resistant silk-diets on the growth and development of fall armyworm and corn earworm from a laboratory and a I wild colony were compared in laboratory and field studies. For both species, there were significant interactions between insect strain and diet treatments. Compared to the laboratory strains, the I wild strains produced lighter larvae and required longer developmental times when reared on diets with and without resistant silks. Larval growth of both insect strains was significantly retarded by the addition of resistant silks to the diets. In field studies, the I wild strains generally performed better than the laboratory strains. For both insect species, interactions between insect strains and corn lines were observed. Strain differences for all measured parameters were greater for the corn earworm than for the fall armyworm. Results from these studies indicate that research on plant resistance for the fall armyworm and the corn earworm would better predict the relative levels of resistance among different corn lines and among different silk diets if I wild colonies were established annually, and if insects from these I wild colonies were used in conducting laboratory and field bioassays.
Investor Sentiment in an Artificial Limit Order Market

This paper examines the under/overreaction effect driven by sentiment belief in an artificial limit order market when agents are risk averse and arrive in the market with different time horizons. We employ agent-based modeling to build up an artificial stock market with order book and model a type of sentiment belief display over/underreaction by following a Bayesian learning scheme with a Markov regime switching between conservative bias and representative bias. Simulations show that when compared with classic noise belief without learning, sentiment belief gives rise to short-term intraday return predictability. In particular, under/overreaction trading strategies are profitable under sentiment beliefs, but not under noise belief. Moreover, we find that sentiment belief leads to significantly lower volatility, lower bid-ask spread, and larger order book depth near the best quotes but lower trading volume when compared with noise belief.
A COMPARATIVE STUDY OF VEGETATIVE AND REPRODUCTIVE GROWTH OF LOCAL WEEDY AND CLEARFIELD ® RICE VARIETIES IN MALAYSIA

The movement from transplanting to direct seeding has brought weedy rice problems in Malaysia’s rice granary areas. Weedy rice ( Oryza spp.) is very difficult to control compared to other weeds due its close genetic relationship to the cultivated rice ( Oryza sativa L.), therefore it cannot be controlled with conventional rice herbicides. Recently, a new technology for controlling weedy rice in rice fields which is known as Clearfield ® Production System has been introduced by discovering the combination of herbicide imidazolinone and resistant trait containing variety. Two cultivars have been released by Malaysia known as MR 220CL1 and MR 220CL2 which were derived from crosses between CL1770 from Louisiana State University with a Malaysian local rice variety, MR 220. The objective of the study is to understand the growth patterns (vegetative and reproductive) of four different weedy rice morphotypes and two variants of Clearfield ® rice in Malaysia. Weedy morphotypes were observed being significantly taller in all growth stages compared to Clearfield ® . Tillering abilities of weedy morphotypes were not different from Clearfield ® variants except for WR4 at 60 days after seeding (DAS). Flowering and maturity periods observed in weedy morphotypes were ranged widely where all weedy morphotypes flowered 10 to 20 days later than the Clearfield ® rice varieties. Understanding all these morphological and physiological characteristics of weedy rice is useful to improve the weedy rice management and good agricultural practices for better control of escaped weedy rice in the Clearfield ® planting areas.
A Synchronized Hybrid Brain-Computer Interface System for Simultaneous Detection and Classification of Fusion EEG Signals

Brain-computer interface (BCI) technology represents a fast-growing field of research and applications for disabled and healthy people, which is a direct communication pathway to translate the neural information into an active command. Owing to the complicated headset structure, low accuracies, extended training periods, and nonstationary noises, BCI still has many challenges that should be dealt with for further facilitation of BCI technology use in daily life. In this study, a simplified synchronized hybrid BCI system is proposed for multiple command control by the electroencephalograph (EEG) signals in the motor cortex. This system can detect the single motor imagery (MI) task, single steady-state visually evoked potential (SSVEP) task, and hybrid MI + SSVEP tasks simultaneously (total ten mental tasks) via 2 EEG channels with high accuracy. The fast independent component analysis algorithm is employed to hybrid signals for obtaining clear EEG signals resulting from denoising. Feature extraction is performed by the wavelet transform, which is extracted by the features in the frequency and time domains. Furthermore, a four-layer convolutional neural network (CNN) is used as a classifier to distinguish different mental tasks. Finally, the hybrid MI + SSVEP system with a simple structure achieves a high accuracy of 95.56%. Additionally, the single MI-based and the SSVEP-based BCI system obtain the classification accuracy of 90.16% and 93.21%, respectively. Experimental results indicate that the synchronized hybrid BCI system could achieve multiple command control with a simple structure. In comparison with the single MI-based and the SSVEP-based BCI system, the hybrid MI + SSVEP BCI system shows a stable performance and higher efficiency. The proposed investigation provides a new method for the multiple command control by a hybrid BCI system. Also, the proposed BCI system offers the possibility of friendly utilization for disabled people because of its reliability, ease of use, and simplified headset structure.
Impacts of thinning and fertilization on timber and energy wood production in Norway spruce and Scots pine: scenario analyses based on ecosystem model simulations

Summary Based on model simulations, we studied the sensitivity of the production of energy biomass and timber to varying precommercial stand densities. Additionally, we studied their sensitivity to varying thinning regimes alone or combined with nitrogen fertilization. The net present value (NPV) was used to identify the cost-efficiency of management regimes. The simulations were done for Norway spruce grown on fertile (OMT) and medium fertile (MT) sites and Scots pine grown on medium fertile and poor (VT) sites in Finland. For Norway spruce, the modelled stem wood production was the highest when the pre-commercial stand was very dense and late energy wood thinning was modelled together with fertilization. For Scots pine grown on the MT site, the response was similar to Norway spruce. However, on the VT site, the modelled stem wood production was the highest, when the pre-commercial stand was moderately dense and early energy wood thinning was modelled with fertilization. NPV was the highest when the pre-commercial stand was very dense, providing early income. However, energy wood price of 3–11 € m 3 would be needed to make the integration of timber and energy wood production more profitable than that aiming for timber production alone without any subsidies.
Litter quality and environmental controls of home-field advantage effects on litter decomposition

The ‘home-field advantage (HFA) hypothesis’ predicts that plant litter is decomposed faster than expected in the vicinity of the plant where it originates from (i.e. its ‘home’) relative to some other location (i.e. ‘away’) because of the presence of specialized decomposers. Despite growing evidence for the widespread occurrence HFA effects, what drives HFA is not understood as its strength appears highly variable and context-dependent. Our work advances current knowledge about HFA effects by testing under what conditions HFA is most important. Using published data on mass loss from 125 reciprocal litter transplants from 35 studies, we evaluated if HFA effects were modulated by macroclimate, litter quality traits, and the dissimilarity between ‘home’ and ‘away’ of both the quality of reciprocally exchanged litters and plant community type. Our results confirmed the occurrence of an overall, worldwide, HFA effect on decomposition with on average 7.5% faster decomposition at home. However, there was considerable variation in the strength and direction (sometimes opposite to expectations) of these effects. While macroclimate and average litter quality had weak or no impact on HFA effects, home-field effects became stronger (regardless of the direction) when the quality of ‘home’ and ‘away’ litters became more dissimilar (e.g. had a greater dissimilarity in N:P ratio; F1,42 = 6.39, p = 0.015). Further, home-field effects were determined by the degree of difference between the types of dominant plant species in the ‘home’ versus ‘away’ communities (F2,105 = 4.03, p = 0.021). We conclude that home-field advantage is not restricted to particular litter types or climate zones, and that the dissimilarity in plant communities and litter quality between the ‘home’ and ‘away’ locations, are the most significant drivers of home-field effects.
Genetics of earliness in brinjal (Solanum melongena L.)

A7 x 7 diallel analysis was done to study the genetic architecture of brinjal for earliness. Non-additive gene effect was found relatively more important for earliness in brinjal. The parents RCMB-10, RCMB-7 and RCMB-1 were good general combiners for earliness, and the crosses namely, RCMB-10 x RCMB-3, RCMB-10 x BB-64, RCMB-7 x RCMB-4, RCMB-1 x BB-40 and RCMB-1 x BB-64 were recorded as good specific combiners for these traits.
CAN PLANTS STIMULATE SOIL MICROBES AND THEIR OWN NUTRIENT SUPPLY? EVIDENCE FROM A GRAZING TOLERANT GRASS

The primary source of mineral nutrients for plants is the decomposition of organic matter by soil microbes. Plants are traditionally viewed as largely passive participants in the decomposition process, incapable of directly affecting rates of decomposition significantly and primarily assimilating nutrients unused by the microbial pool. We performed a 13C pulse-chase experiment on a common grazing tolerant grass, Poa pratensis L. , of Yellowstone National Park, to follow carbon flow into the soil rhizosphere and microbial biomass and the associated effects on soil N availability and plant N dynamics. Grazing promoted root exudation of carbon, which was quickly assimilated into a burgeoning microbial population in the rhizosphere of clipped plants. Moreover, these facilitating effects of defoliation on rhizospheric processes positively fed back on soil inorganic N pools, plant N uptake, leaf N content, and photosynthesis. Such findings are the first evidence, to our knowledge, that suggest (1) plants are cap.
Reduced antennal sensitivity, behavioural response, and attraction of male codling moths, Cydia pomonella, to their pheromone (E,E)‐8,10‐dodecadien‐1‐ol following various pre‐exposure regimes

The effects of pre‐exposing male codling moths, Cydia pomonella (L.) (Lepidoptera: Tortricidae), to their pheromone (E,E)‐8,10‐dodecadien‐1‐ol (codlemone), in static and moving air, under laboratory and field conditions, on subsequent antennal sensitivity, behavioural responsiveness, and attraction to codlemone were investigated. In flight tunnel experiments, the percentage of moths wing fanning and taking flight were mostly unaffected, but upwind flight to, and contact with, pheromone sources known to elicit responses of both were shown to depend on the intensity and duration of previous exposure to codlemone and recovery time between exposure and assessment. Ten to 30‐min pre‐exposures to codlemone in static air (≈ 35 µg l−1) not only caused a 99% reduction in attraction, but also significantly reduced electroantennogram response to codlemone. Recovery of full antennal sensitivity to codlemone took more than 1 h, but recovery of attraction took over 4 h, suggesting that habituation is also partially involved in reduced behavioural responsiveness following pre‐exposure. Seventy‐five min exposures to codlemone in moving air (5–10 cm s−1) at rates of 0.9, 4.5, and 18 µg h−1 from Celcon fibres caused 75, 86, and 99% disruption, respectively. However, 30–34‐h exposure of caged moths to air moving through an orchard treated with 1000 Isomate‐C® dispensers ha−1 releasing approximately 20 µg h−1 per dispenser during tests, had no impact on moth response in flight‐tunnel assays 30 min after removal from the orchard. In this treated orchard, catches of free‐flying moths in pheromone‐baited traps were completely inhibited. If observed mechanisms such as long‐lasting antennal adaptation or habituation of the central nervous system contribute to the disruption of pheromone communication among codling moths under field conditions, it seems unlikely that they occur following exposure to the average atmospheric concentrations of codlemone. For these effects to be important, codling moths may require close contact with pheromone sources for extended periods, or repeated close encounters.
Effects of supplementary concentrate level with grass silage, and separate or total mixed ration feeding, on performance and carcass traits of finishing steers

sues. Silage DM intake decreased (P < 0.001) but total DM intake increased (P < 0.001) with increasing concentrate level. Average live-weight gains for SO, LS, LM, MS, MM and AL was 0.34, 0.86, 0.86, 1.02, 1.00 and 1.12 (s.e. 0.064) kg/day, respectively. Corresponding carcass weight gains were 0.25, 0.58, 0.58, 0.71, 0.68 and 0.82 (s.e. 0.028)
Studies on the virulence of tubercle bacilli. The relationship of the physiological state of the organisms to their pathogenicity.

On the basis of earlier observations dealing with the relation of a petroleum ether-soluble material (cord factor) obtained from young cultures of virulent tubercle bacilli to the pathogenicity of these organisms, it was expected that young cultures yielding more cord factor than older ones of the same strain would also be more virulent for susceptible animals. By infecting mice with equal numbers of bacteria from 3 day and 3 week old cultures, significant differences in the character of disease produced were observed. The mice infected with the younger cultures died of a rapid, septicemic infection with tuberculous lesions in many organs including the heart. A tuberculous myocarditis was probably the immediate cause of death. Mice infected with the older bacteria died of a chronic disease corresponding to the well known mouse tuberculosis. In these cases, the heart was completely free of lesions. No histologic tissue reactions typical of tuberculosis were seen in the animals dying from the acute type of the disease. A similar rapidly progressing infection was observed in rabbits infected with bacteria from young cultures. The symptoms corresponded to the ones seen in the disease known as the Yersin type of tuberculosis. It seems that the pathology of this latter can be produced with every type of pathogenic mycobacteria, human as well as bovine and avian, provided the cultures used are young. Thus it may be inferred that the acute type of tuberculosis is more frequent than commonly accepted both in experimental infection and in the naturally occurring disease. It is proposed to explain the mechanism of this acute infection within the framework of the cord factor hypothesis.
Influence of feeding regime on intraspecific competition, fin damage and growth in 1+ Atlantic salmon parr (Salmo salar L.) held in freshwater production cages

The feeding behaviour, growth and feed conversion ratio (FCR) of cage-held Atlantic salmon parr (Salmo salar L.) were studied when in 576 m3 (12 m × 12 m × 4 m) commercial freshwater cages under ambient water temperature (8.84±3.53°C) and photoperiod (11.02±2.05 h) for 205 days. The effect of feeding regime on fin damage was also investigated. Six groups (n=31 234±2051 fish group−1, initial stocking density 1.25±0.14 kg m−3) were fed to satiation using either (a) an imposed regime involving scheduled, fixed ration feeding every 10 min from dawn till dusk or (b) on demand from dawn till dusk using commercial interactive feedback systems. During feeding, there were no significant differences in aggression although swimming speeds and turning angles were significantly higher in fish under the imposed regime. On-demand feeding significantly reduced the incidence of dorsal fin damage. There was no clear relationship between fish size, feed regime and the incidence of fin damage until 1 week before the fish were transferred to marine cages, when the smallest fish under each feeding regime had the highest incidence of fin damage. Interestingly, growth did not differ between regimes, but fish under the imposed regime were significantly overfed and achieved higher FCRs.
Tree form and taper variation over time for interior lodgepole pine

Changes in tree form and taper over time, as affected by changes in tree, stand, and site factors for interior lodgepole pine (Pinuscontorta var. latifolia Engelm.) were investigated using detailed stem analysis data from interior British Columbia. It was found that tree shape and taper change along the stem at one time and over time with changes in tree and stand factors, particularly the diameter at breast height to total tree height ratio, crown length, and crown ratio, and with predicted quadratic mean diameter at age 50 years, a stand density measure. At young ages, the trees were parabolic in shape from ground to top. However, as they increased in size over time, different portions of the stem took different shapes because of unequal growth in diameter along the stem. Changes in tree shape and taper over time were closely related to the crown size, which is related to stand density.
ETIOLOGY AND EPIDEMIOLOGICAL VARIABLES ASSOCIATED WITH MAIZE RESISTANCE TO WHITE SPOT DISEASE

SUMMARY Maize white spot disease (MWSD) has become most important in Brazil. With this study the susceptible maize hybrid DAS657 was artificially inoculated under greenhouse conditions with the bacterium Pantoea ananatis and the fungus Phaeosphaeria maydis, the two most likely candidate etiological agents of MWSD. Plants inoculated with P. ananatis reproduced the symptoms typical of MWSD, while several attempts to fulfill Koch’s postulates with P. maydis failed. The epidemiological variables associated with maize resistance to MWSD was assessed with eight simple hybrids, one double hybrid, one triple hybrid and five inbred lines evaluated in two trials in a randomized block design with three replicates in two planting times. The area under disease progress curve (AUDPC) and disease severity at the end of the epidemic (Y max ) were the epidemiological variables that better differentiated maize genotypes resistant to MWSD. One inbred line and three simple hybrids were highly resistant. Two inbred lines were identified as new sources of resistance and may be used in maize breeding programs.
Explanations of commonness and rarity in British breeding birds: separating resource use and resource availability

Two of the most prominent explanations for a positive interspecific relationship between local abundance and regional distribution are the resource breadth and the resource availability hypotheses. Here we test these hypotheses by characterising habitat use of British breeding birds using extensive census and environmental data. A group of 85 bird species was considered for study along with 34 land use or environmental variables, which were used to generate four ordination axes by Canonical Correspondence Analysis. Measures of niche breadth and position were derived from these synthetic environmental axes using standard procedures. Across species, none of five measures of abundance and distribution chosen were correlated with niche breadth, whereas four out of five of these measures were correlated negatively with niche position. Repeating the analyses using a method designed to control for phylogenetic non-independence confirmed these general patterns. Birds that tended to use resources that were more atypical of the environment tended to be rarer and thinly distributed, while those using typical resources were common and widely distributed. Performing the analyses on subsets of the data based on species sample sizes did not alter the conclusions. On the assumption that our analyses properly capture patterns of niche use by birds, we find little support for the resource breadth hypothesis, but considerable support for the resource availability hypothesis.
