The effects of future consumption by the Cape fur seal on catches and catch rates of the Cape hakes. 2. Feeding and diet of the Cape fur seal Arctocephalus pusillus pusillus

The current status of and future trends for the Cape fur seal Arctocephalus pusillus pusillus population are assessed using information from aerial counts of pup abundance. The model used in the analyses is age- and sex-structured, and assumes density-dependence in the survival rate of pups. Uncertainty is assessed by conducting sensitivity tests and estimating 90% confidence intervals by the percentile method. The results confirm the increase of the seal population since the introduction of legal controls at the end of the 19th century, and the estimate of 1,7 million animals of Age 1 and older at the start of 1993 is relatively robust to model assumptions and values for biological parameters. The food consumption by the seal population is estimated to have almost doubled between 1973 and 1993, and to be roughly 2 million tons annually at present. Future trajectories of seal numbers and annual consumption of food cannot be determined with great precision and are sensitive to the values assumed for the po.
Facteurs influençant les paramètres de reproduction des brebis Ouled Djellal

The study of the reproductive parameters of the ewes Ouled Djellal (n=269), conducted in semi-intensive in semi-arid environment, shows a fertility rate of 88 %, a fecundity rate of 95 % and a prolificacy rate was 111 %. The influence of different factors on the reproduction parameters, highlights on fertility, a significant influence (p<0.05) of the physiological state during the mating, an effect very significant of ewes age and a result highly significant (p<0.001) of mode of mating, of month of mating and for the interaction of physiological state during the mating × mode of mating. For fecundity, there is a significant effect (p<0.05) of the ewes age, very significant (p<0.01) of the physiological state during the mating and highly significant (p<0.001) for mode of mating and the month of mating. As for prolificacy, it is significantly influenced by the physiological state during the mating and very significantly by the month of mating.
Non‐stationarity and local approaches to modelling the distributions of wildlife

Despite a growing interest in species distribution modelling, relatively little attention has been paid to spatial autocorrelation and non‐stationarity. Both spatial autocorrelation (the tendency for adjacent locations to be more similar than distant ones) and non‐stationarity (the variation in modelled relationships over space) are likely to be common properties of ecological systems. This paper focuses on non‐stationarity and uses two local techniques, geographically weighted regression (GWR) and varying coefficient modelling (VCM), to assess its impact on model predictions. We extend two published studies, one on the presence–absence of calandra larks in Spain and the other on bird species richness in Britain, to compare GWR and VCM with the more usual global generalized linear modelling (GLM) and generalized additive modelling (GAM). For the calandra lark data, GWR and VCM produced better‐fitting models than GLM or GAM. VCM in particular gave significantly reduced spatial autocorrelation in the model residuals. GWR showed that individual predictors became stationary at different spatial scales, indicating that distributions are influenced by ecological processes operating over multiple scales. VCM was able to predict occurrence accurately on independent data from the same geographical area as the training data but not beyond, whereas the GAM produced good results on all areas. Individual predictions from the local methods often differed substantially from the global models. For the species richness data, VCM and GWR produced far better predictions than ordinary regression. Our analyses suggest that modellers interpolating data to produce maps for practical actions (e.g. conservation) should consider local methods, whereas they should not be used for extrapolation to new areas. We argue that local methods are complementary to global methods, revealing details of habitat associations and data properties which global methods average out and miss.

LOCAL WISDOM: CAN IT MITIGATE THE RISK OF FRAUD?

Histori Artikel : Tgl. Masuk : 27-02-2020 Tgl. Diterima : 10-03-2020 Tersedia Online : 20-04-2020 The risk of fraud in managing village funds is increasingly proportional to the increasing amount of funds provided by the central government every year. One of the ways that the government can use to mitigate the risk of fraud is to implement local wisdom. This research was conducted to identify the fraud risk that occurs in managing village funds in Kebonan Village and analyze local wisdom as one of the media to mitigate fraud in the management of village funds in the village. This research uses descriptive qualitative data method with primary data sources. The instrument used in the study was a semi-structured interview. The result of this study shows that even though there is already control to reduce and manage every fraud risk, local wisdom also can be used as a means of mitigating the fraud risk if it is properly imbued.
Variation in Growth Performance and Carcass Yield of Pure and Reciprocal Crossbred Turkeys

Abstract This study compared growth, feed conversion ratio (FCR), mortality rate and results of slaughter analysis of slow-growing Bronze turkeys (SG), fast-growing Big 6 turkeys (FG), and their reciprocal crosses (SF and FS). Until 6 weeks of age the birds were kept indoors and afterwards they were allowed to use free ranges. Toms were reared until 21 and hens until 15 weeks of age. The FS turkeys were characterized by higher (P≤0.05) BW and dressing percentage and by lower FCR compared to the SF crosses of both sexes. The analysis of orthogonal contrasts demonstrated that values of most of the slaughter analysis parameters were due to the additive effect of genes. Only weight of skin with fat and of gizzard could result from heterosis. Study results demonstrate that FS crosses constitute better material for the alternative production of turkeys compared to the other analysed groups (SG, SF, FG).
Disturbed Blood Flow Acutely Increases Endothelial Microparticles and Decreases Flow Mediated Dilation in Patients With Heart Failure With Reduced Ejection Fraction

Introduction Disturbed blood flow, characterized by high retrograde and oscillatory shear rate (SR), is associated with a proatherogenic phenotype. The impact of disturbed blood flow in patients with heart failure with reduced ejection fraction (HFrEF) remains unknown. We tested the hypothesis that acute elevation to retrograde and oscillatory SR provoked by local circulatory occlusion would increase endothelial microparticles (EMPs) and decrease brachial artery flow-mediated dilation (FMD) in patients with HFrEF. Methods Eighteen patients with HFrEF aged 55 ± 2 years, with left ventricular ejection fraction (LVEF) 26 ± 1%, and 14 control subjects aged 49 ± 2 years with LVEF 65 ± 1 randomly underwent experimental and control sessions. Brachial artery FMD (Doppler) was evaluated before and after 30 min of disturbed forearm blood flow provoked by pneumatic cuff (Hokanson) inflation to 75 mm Hg. Venous blood samples were collected at rest, after 15 and 30 min of disturbed blood flow to assess circulating EMP levels (CD42b−/CD31+; flow cytometry). Results At rest, FMD was lower in patients with HFrEF compared with control subjects (P < 0.001), but blood flow patterns and EMPs had no differences (P > 0.05). The cuff inflation provoked a greater retrograde SR both groups (P < 0.0001). EMPs responses to disturbed blood flow significantly increased in patients with HFrEF (P = 0.03). No changes in EMPs were found in control subjects (P > 0.05). Disturbed blood flow decreased FMD both groups. No changes occurred in control condition. Conclusion Collectively, our findings suggest that disturbed blood flow acutely decreases FMD and increases EMP levels in patients with HFrEF, which may indicate that this set of patients are vulnerable to blood flow disturbances.
Timescales of chemical equilibrium between the convecting solid mantle and over-/underlying magma oceans

After accretion and formation, terrestrial planets go through at least one magma ocean episode. As the magma ocean crystallises, it creates the first layer of solid rocky mantle. Two different scenarios of magma ocean crystallisation involve that the solid mantle either (1) first appears at the core–mantle boundary and grows upwards or (2) appears at mid-mantle depth and grows in both directions. Regardless of the magma ocean freezing scenario, the composition of the solid mantle and liquid reservoirs continuously change due to fractional crystallisation. This chemical fractionation has important implications for the long-term thermo-chemical evolution of the mantle as well as its present-day dynamics and composition. In this work, we use numerical models to study convection in a solid mantle bounded at one or both boundaries by magma ocean(s) and, in particular, the related consequences for large-scale chemical fractionation. We use a parameterisation of fractional crystallisation of the magma ocean(s) and (re)melting of solid material at the interface between these reservoirs. When these crystallisation and remelting processes are taken into account, convection in the solid mantle occurs readily and is dominated by large wavelengths. Related material transfer across the mantle–magma ocean boundaries promotes chemical equilibrium and prevents extreme enrichment of the last-stage magma ocean (as would otherwise occur due to pure fractional crystallisation). The timescale of equilibration depends on the convective vigour of mantle convection and on the efficiency of material transfer between the solid mantle and magma ocean(s). For Earth, this timescale is comparable to that of magma ocean crystallisation suggested in previous studies (Lebrun et al., 2013), which may explain why the Earth’s mantle is rather homogeneous in composition, as supported by geophysical constraints.
Structural Characteristics of Grasshopper Sparrow Habitat

Based on data from Breeding Bird Survey routes, the grasshopper sparrow (Ammodramus savannarum) has declined in West Virginia (Whitmore and Hall 1978). In much of the mid-Appalachians, surface-mine reclamation procedures have created large tracts of grassland that have potential for use by grasshopper sparrows (Allaire 1978, Whitmore 1978, Whitmore and Hall 1978). Because of the availability of this new habitat, grasshopper sparrows have become locally common in West Virginia, reaching population densities of 120 pairs/100 ha (Whitmore 1979). Because little was known about grasshopper sparrows (Smith 1963), my study was designed to quantify their habitat requirements, with special reference to key aspects of vegetation structure. The procedures outlined could serve as a basis
River Ecosystem Health Down Under: Assessing Ecological Condition in Riverine Groundwater Zones in Australia

Below many rivers and extending laterally beneath their banks lies a zone of saturated sediments—the hyporheic zone. This region is the site of dynamic exchanges of water and materials between the groundwater below, lateral alluvial aquifers, and the river flowing above. In this centrally located ecosystem component, the actions of the microbial biofilms coating the sediments are considered to act like a biological filter, enhancing water quality during the exchange process. However, the hyporheic zones in many rivers are threatened by siltation, toxicants and increasing acidity, physical extraction for gravel, or altered groundwater inputs through pumping. Current protocols to assess river health do not explicitly consider that of the hyporheic zone, despite its central role in many rivers. This oversight is due largely to the relative infancy of the discipline of hyporheic research, limited communication to river managers by ecologists, and technical difficulties in sampling the hyporheic zone. Ecosystem health assessments in rivers with potentially important hyporheic zones could include measurements of the extent of hydrological exchange between the river and the hyporheic zone at a range of scales, the rates of some key interstitial chemical processes, and perhaps the biodiversity of hyporheic invertebrates. In Australia, the potential of some of these measurements is being investigated, especially in relation to assessing the health of “groundwater-dependent ecosystems. ”
A Novel Method for Computationally Efficacious Linear and Polynomial Regression Analytics of Big Data in Medicine

Background: Machine learning relies on a hybrid of analytics, including regression analyses. There have been no attempts to deploy a scale-down transformation of data to enhance linear regression models. Objectives: We aim to optimize linear regression models by implementing data transformation function to scale down all variables in an attempt to minimize the sum of squared error. Materials and Methods: We implemented non-Bayesian statistics using SPSS and MatLab. We used Excel to generate 40 trials of linear regression models, and each has 1,000 observations. We utilized SPSS to conduct regression analyses, Wilcoxon signed-rank test, and Cronbach’s alpha statistics to evaluate the performance of the optimization model. Results: The scale-down transformation succeeded by significantly reducing the sum of squared errors [absolute Z-score=5.511, effect size=0.779, p-value<0.001, Wilcoxon signed-rank test]. Inter-item reliability testing confirmed the robust internal consistency of the model [Cronbach’s alpha=0.993]. Conclusions: The optimization model is valuable for high-impact research based on regression. It can reduce the computational processing demands for powerful real-time and predictive analytics of big data.
Effect of seaweed extract and biofertilizer on organic production of common bean seeds (Phaseolus vulgaris L.)

At the Experimental Farm, Agriculture Faculty, University of Ain Shams, Qaliobia Governorate, Egypt, in order to investigate the influence of biofertilizer ( Bio. ); Rhizobium ( R ), mycorrhiza ( MF ), R + MF and control, seaweed extract (SWE) concentration (zero, one, two and four gram per liter) and their interactions on vegetative growth, productivity and quality of seed common bean cv. Nebraska. Before planting, the seeds were soaked in MF (glomus sp.) and sown on the first of March 2016 and 2017 seasons respectively. The experimental plot area was seven m2 (four rows). The length of each row was 2.5 m and width of 0.7 m. The plant's distance was seven cm on one side, and an alley (one width m) was left as a border between the treatments. After two weeks of planting, young plant were inoculated with R phaseolus after the first irrigation. Plants were sprayed three times of SWE (30, 45 and 60 days) after sowing. A split plot design with four replicates was used; where the main plots are Bio treatments and the subplots are SWE treatments. The obtained results clearly indicated that different applied treatments increased measured growth characteristics (No. leaves/ plant, leaf area and total chlorophyll (SPDS)), the yield and components of yield (No. pods/plant, seed yield /plant and seed yield) and chemical constituents (total protein, carbohydrates, nitrogen and phosphorus) in seed after harvest. As well as, the best results were obtained by interactions between SWE (two and four gram per liter) and Bio. (R + MF) treatments in the two assigned seasons So adding combination between Bio. ( R + MF ) and SWE (two or four g) to improve vegetative growth, productivity and quality of common bean seed could be recommended under organic system ( conversion to organic agriculture ).
Suitability of Lake Sturgeon Growth Rings inChronology Development

Abstract The purpose of this investigation was to determine if ring widths in the cross section of lake sturgeon pectoral fin rays satisfy three criteria required of structures used in the development of growth chronologies. First, ring widths must be related to the overall somatic growth of the organism. Second, ring widths must demonstrate synchrony of interannual growth variation among individuals within a population. Finally, fin ray rings and growth chronologies should be related to both interpopulation and interannual variations of known environmental factors. This research indicated that ring widths document variations in somatic growth. Average fin ray cross-sectional radii at age 25 were related to total length using data from seven populations sampled across North America. This investigation also suggested that growth ring widths were influenced by large-scale, population-wide, extrinsic factors in two ways. First, differences between populations in fin ray cross-sectional radii at age 25 were s.
Pollen morphology of some Turkish Campanula spp. and their taxonomic value

Detailed pollen morphological structures of 12 Turkish species of Campanula L. , e.g. C. argaea, C. cymbalaria, C. glomerata subsp. hispida, C. latiloba subsp. latiloba, C. lyrata subsp. lyrata, C. olympica, C. persicifolia, C. pterocaula, C. rapunculoides subsp. cordifolia, C. rapunculus var. rapunculus, C. stricta var. stricta, C. pamphylica subsp. tokurii have been studied under light (LM) and scanning electron microscopes (SEM) for the first time. LM and SEM investigations show that the pollen grains of 12 taxa are more or less oblato-sphaeroidal, triporate (and/or tetraporate), tectum-scabrate, or with circular amb. The exine sculpture is granulate-scabrate in C. argaea, C. lyrata subsp. lyrata, C. stricta var. stricta, C. glomerata subsp. hispida and C. pamphylica subsp. tokurii; but those of C. cymbalaria, C. latiloba subsp. latiloba, C. olympica, C. persicifolia, C. pterocaula, C. rapunculoides subsp. cordifolia and C. rapunculus var. rapunculus are rugulate-scabrate. Introduction Campanula L. (Campanulaceae) is mainly a Northern hemisphere and Mediterranean genus and consists of 130 species of which 66 are endemic to Turkey (Damboldt 1978, Davis et al. 1988, Guner et al. 2001, Ocak 2003, Akcicek et al. 2005). As pollen structures are micro-morphological attributes that can be used both to distinguish related taxa and also to integrate them into a common group. The morphological features of pollen grains of some of the Campanula species have been dealt with by several authors (Oybak and Pinar 1995, Perveen and Qaiser 1999, Ocak 2003, Akcicek et al. 2005), and a detailed account of the pollen morphology of some Turkish Campanula species has been given by Inceoglu (Inceoglu 1976). The pollen characters of all Turkish Campanula species are yet to be studied in detail. The purpose of this study is to determine through the use of LM and SEM, the extent to which morphological differences are well evaluated in 12 Turkish species of Campanula, five of which are endemic species to Turkey. This study also aims to throw light on the problematic aspects of taxonomy and evolution. Materials and Methods Pollen material was obtained from the Faculty of Science and Arts of Eskisehir Osmangazi University Herbarium (OUFE). For the purpose of LM investigations, pollen grains from herbarium materials were collected and prepared according to Wodehouse (1935) and Erdtman (1960). The pollen dimensions of all species were measured in such amounts that the resulting data followed Gaussian curves (Ozdamar 2004). These measurements are shown in Table 1. For SEM investigations, the unacetolyzed pollen grains were directly placed on stubs, sputter-coated with gold plate, and examined with a Jeol 5600 LV scanning electron microscope (Walker 1974a,b). The terminologies for pollen morphology proposed by Skvarla (1966), Erdtman (1969), Walker (1974a,b), Charpin et al. (1974) and Faegri and Iversen (1975) were employed. Correspondence author.

Feed intake and nutrient digestibility of weaner rabbits fed cassava peel as replacement for maize

Twenty 8-week old crosses of New Zealand White X Chinchila weaner rabbits were used to assess the performance of rabbits fed diets with cassava peel replaced with maize on a graded level. Five diets were formulated, diets 1 (control), 2, 3, 4, and 5 in which maize was replaced with cassava peel at 0%, 25%, 50%, 75%, and 100%, respectively. The 20 rabbits were used in a completely randomized design with five treatments and four animal replicates per treatment. The trial lasted for 8 weeks. Parameters measured were feed intake, weight gain, feed conversion ratio and feed cost per kg. It was observed that there was no significant difference (P > 0.05) in the average daily feed intake of the rabbits fed diets 3, 4 and 5. However, diets 3, 4 and 5 had significantly higher (P < 0.05) intake than diets 1 and 2. Similarly, rabbits on diets 3, 4 and 5 had higher (P < 0.05) growth rates than those fed the control diet and diet 2. Feed cost per kg (N/kg) decreased from N35.33 in the control diet to N19.75 in diet 5. Cost of feed/kg live weight gain (N/day) decreased from N3.21 in the control diet to N1.29 in diet 5. It was concluded that maize supplementation in the diets of weaner rabbits could be replaced by cassava peels up to 100 % without any adverse effect. However, 75% cassava peel replacement was found to be the optimum and therefore recommended.
