Water‐related bird assemblages in an urban pond ‘archipelago’: Winter patterns of bird species occurrence, abundance and richness

This study reports on the patterns of species occurrence, abundance and richness of a wintering water-related bird assemblage in an ‘archipelago’ of 70 small artificial urban ponds (AUPs) embedded in a metropolitan landscape (Rome, central Italy). A total of 20 species in 26 AUPs were sampled. Only the largest AUPs (>0.1 ha) contained all these species, except for Gallinula chloropus. The highest total mean species abundance was observed in the largest ponds, with statistically significant differences evident among size classes. Two significant spatial thresholds in species abundance and richness were observed (between 0.01 and 0.1 ha; between 0.1 and 1 ha in size). The abundance of single species was correlated with their frequency of occurrence. Ponds in urban areas must be larger than 0.1 ha to host a rich winter assemblage of birds, with a further increase in richness noted with a surface area larger than 1 ha. The highest number of species was observed in the larger ponds (>1 ha). The species richness of each AUP is directly correlated to their size (log-transformed species–area relationship: log S = 3.515 + 0.497 log A; R2 = 0.76). Further research should be conducted to confirm these patterns and to implement information useful for planning and management of artificial ponds in urban areas for this purpose.
Determinants of Technical Inefficiencies of Sweet Potato Farming in Kuningan District

The study was conducted to analyse the technical inefficiency of sweet potato farming in Kuningan District. 51 farmers were analysed using the stochastic frontier production function. The sample is determined using simple random sampling with one output and six inputs (land, seed, organic fertilizer, chemical fertilizer, pesticides and labour). The results showed that the average technical efficiency was 66%. The technical inefficiency model shows that non-formal education, experience, and family size have a significant effect on technical inefficiency.
Experimental soil-warming effects on carbon processes of typical meadow Calamagrostis angustifolia wetland ecosystem in the Sanjiang Plain, northeast China

Abstract To examine the effects of soil warming on carbon-accumulation and -release processes in the wetland ecosystem, a field-warming experiment was conducted under flooded and unflooded water conditions in the typical meadow Calamagrostis angustifolia (C. angustifolia) (TMC) wetland in the Sanjiang Plain, northeast China. Warming cables were used to simulate soil warming. Warming caused significant increases in aboveground biomass compared with belowground biomass during the growing season, and the enhancement of aboveground biomass increased with plant growth while belowground biomass showed an opposite effect. Significant positive correlation was found between aboveground biomass and 10–20-cm soil content whereas belowground biomass was more significantly correlated with 0–10-cm soil content. Positive linear correlations were found between CO2 and CH4 fluxes and warming-induced changes in liable carbon (LBC) and carbohydrate carbon (CHC) contents. Flooded water conditions tended to increase the accumulation of belowground biomass, content and CH4 fluxes under warming treatment. Soil warming could not only stimulate the carbon-accumulation and -release processes in the TMC wetland ecosystem directly, but also indirectly through the enhancement of nitrogen availability and active carbon contents. The contents of and active carbon could be sensitive indicators for the carbon-process changes in wetland ecosystems under soil warming.
Impact of Chronic Medical and Neuropsychiatric Illnesses on Quality of Life and Life Expectancy among Patients at the University of Port Harcourt Teaching Hospital (UPTH)

The prevalence of chronic medical and psychiatric diseases has continued to increase worldwide, and their consequences have remained a growing concern. Acting with a number of sociodemographic and clinical variables, they tend to affect quality of life (QOL) and onward to life expectancy. There is a direct relationship between QOL and life expectancy. Hypertension and diabetes mellitus acting with adverse environmental factors reset and overamplify the sympathetic outflow, and this may worsen hypertension and or cause depression, dysthymia, and anxiety disorders. Tuberculosis and HIV are two chronic infective medical conditions that equally negatively affect quality of life well-being and life expectancy. These chronic medical and psychiatric conditions have been associated with reduced QOL and life expectancy. The aim of this study, therefore, was to determine the impact of chronic medical and psychiatric disorders (HIV, tuberculosis, diabetes mellitus, hypertension, dysthymia, and GAD) on quality of life and life expectancy. Following ethical approval and informed consent from the participants, 40 subjects from each group of HIV, tuberculosis, diabetes mellitus, hypertension, anxiety, and dysthymia were studied using sociodemographic/ clinical questionnaire and the WHOQOL-Bref. The data were analyzed using the SPSS version 20 statistical package. Confidence interval was set at 95% while P-value of less than 0.05 was considered statistically significant. There was reduced QOL on physical, psychological, and social relationship, environment domains, and general health facet, respectively. Chronic medical and psychiatric conditions may contribute to reduced QOL and life expectancy. Management of patients with these conditions should necessarily include attention to their QOL and well-being.
Current status of coastal sediments contamination in the former industrial area of Bagnoli-Coroglio (Naples, Italy)

ABSTRACT The purpose of this study is to investigate the current status of contamination due to the heavy metal and organic substances (PAHs, HC >12, organotin compounds, PCB, DDD, DDE, DDT) pollution of the sediments from the coastal area of the Bagnoli brownfield (Naples, Italy) and draw some hypotheses on the origin and trends of industrial and also geogenic contamination. Surface sediments and cores were collected and analysed. The results showed remarkable concentrations of heavy metals, PAHs, and other substances that are significantly higher than the national guideline values of sea sediment quality. Correlation analyses and spatial distribution analyses showed that generally the inorganic and organic pollutants have similar patterns, confirming the common origin from the industrial activity, but also that some of the studied metals have some natural contribution originated from the geologic setting of the area. The distribution of most of the heavy metals (especially Cd, Hg, Pb, Cu, Zn, partially Cr and Ni) and PAHs are similar, and the highest concentrations were recognised between and just off the piers, but a diffuse contamination is widespread up to the external areas of the site perimeter, rising concern on the diffusion of contaminants to the whole Gulf of Pozzuoli.
Development Effects of Electrification: A Meta-Analysis for Income, Labor and Educational Outcomes

Globally, substantial public and private investment has been allocated to electrification, the benefits of which have remained largely, and intuitively, undisputed. However, a close look at the literature suggests that those benefits are far from consistent across different contexts. In fact, estimates of the impacts of electrification are widely heterogeneous and inconclusive. For example, almost 40 percent of the literature’s estimates find no significant effects on income, with similar results for labor and educational outcomes. This paper synthesizes the impact evaluation studies published between the mid-1980s and mid-2019, focusing on the effects of electrification on education, labor and income outcome-categories. Those studies indicate electrification effects (and 95 percent confidence intervals (CI)) of around eight percent in school enrollment (CI=0.04-0.13),17 percent in employment (CI=0.02-0.34), and 24 percent in income (CI= 0.15-0.35). This paper shows, however, that those averages are biased upward, suggesting the presence of selective publication. The meta-regression estimates indicate a mean-corrected, statistically significant effect of 2.6 percent for school enrollment (CI= 0.01-0.04), 5.3 percent for employment (0.04-0.07), and seven percent for income (0.05-0.09). The study design helps explain the estimates’ heterogeneity—i.e., methodologies and data structures requiring less stringent assumptions tend to return lower estimated effects. These findings suggest that the observed heterogeneity reflects actual dispersion in the underlying effects associated with gender differences, as well as, contextual characteristics of the case study, such as country income per-capita and length of the evaluation period.
Pointing the finger at proton pump inhibitors

This issue of the Biomedical Journal welcomes articles from a wide range of disciplines. We take a look at the optimization of surgical techniques in rabbits and visit some of the medical wonders of stem cell technology. In particular, we highlight Sasmita Biswal′s discussion of an emerging link between the use of proton pump inhibitors and hospital-acquired Clostridium difficile infections, in addition to intriguing data showing that environmental enrichment protects hippocampal neurons from damage in stressed, diabetic rats.
Possible Metabolic Intermediates from IAA to β-Acid in Rice Bran

Five new metabolites related to IAA were isolated from aqueous methanol extract of rice bran and their structures were elucidated by spectroscopic methods to be 5-hydroxy-dioxindole-3-acetic acid (Ia), methyl ester of Ia (Ib), methyl dioxindole-3-acetate (IIb), methyl 5-hydroxyoxindole-3-acetate (IIIb) and methyl oxindole-3-acetate (IVb), respectively. The presence of these metabolites which are likely to be intermediates of oxidation of IAA to β-acid suggests such oxidation pathway operating in rice seed.
Effects of tDCS on Muscle Stiffness in Children with Cerebral Palsy Measured by Myotonometry: A Preliminary Study

Background: The aim of this study was to investigate the influence of transcranial direct current stimulation (tDCS) on the biceps brachii and flexor carpi radialis stiffness in children with cerebral palsy (CP). The authors also aimed to verify the relationship between spasticity and muscle stiffness. Methods: Twelve children with CP (mean ± SD; age, 8 ± 1.3 years; height, 118.7 ± 4.1 cm; weight, 23.0 ± 2.2 kg) were involved in the study. Muscle stiffness was estimated using a MyotonPRO device in a MultiScan pattern of five measurements. Simultaneously, the tDCS stimulation was performed. Spasticity was assessed by a neurologist using the Ashworth Scale. Results: Stiffness of the flexor carpi radialis muscle decreased significantly after tDCS therapy (p = 0.04). There was no significant change in stiffness of the biceps brachii. For all participants, the Spearman rank correlation showed statistically significant and positive relationships between muscle stiffness and the Ashworth Scale (p = 0.04). Conclusions: Transcranial direct current stimulation has a decreasing effect on stiffness and spasticity of the flexor carpi radialis in children with CP. The MyotonPRO device provides objective data and correlates with spasticity measurements.
Advancing Forest Cover Development on a High‐Elevation Sierra Nevada Mine Site with Nutritional Amendments

Selected nutrient amendments were evaluated for their capacity to enhance growth and nutrition of established but stunted Jeffrey pine (Pinus jeffreyi Grev. & Balf.) saplings on an acidic Sierra Nevada surface mine. The amendments were applied by topdressing at three rates each and consisted of Forestcote 22‐4‐6 + Minors, a controlled‐release formulation; Free Flow 29‐3‐4 and Hydro Agri 21‐7‐14, two conventional fertilizers, with the former featuring urea as the predominant N source, whereas that for the latter was exclusively ammoniacal and nitrate forms; and Milorganite 6‐2‐0 + Iron, an organic amendment based on municipal biosolids. All formulations reinvigorated sapling growth, generally more so as the amounts supplied increased, with the Free Flow and Hydro Agri amendments marginally more stimulative than Forestcote and Milorganite. Foliar analysis revealed that fertilized saplings had more N, with concentrations that generally rose with amounts supplied, and P but less Mn and Al than the control. Enhanced N nutrition in particular but also that of P probably accounted for most of the growth stimulation by the amendments, as availability of both in the soil was limiting. Of the two metallic elements, reduced Mn was likely most critical because concentrations encountered here were exceedingly elevated overall, including that in the soil, although soil Al was also high. These results suggest that a variety of nutritional amendments can be employed in forest restoration on surface mine sites and those similarly degraded, including sites for which dry climates greatly influence the selection of remedial practices.
Steady‐state bioassay approach applied to phosphorus‐limited continuous cultures: A growth study of the marine chlorophyte Dunaliella salina

Phosphorus‐limited growth and phosphate uptake kinetics of the marine phytoplankter Dunaliella salina were studied using continuous‐culture techniques. Determination of residual phosphate concentrations in the cultures were made using a steady‐state bioassay approach in which short‐term phosphate uptake rates as measured by 33P‐radiotracer were balanced with the turnover of phosphorus in the culture. This allowed the determination of low‐nanomolar ambient phosphate concentrations (8–95 nmol P L−1) at seven unique specific growth rates, which agreed closely with an alternative kinetics bioassay phosphate determination. The relationship of specific growth rate to ambient phosphate concentration for the D. salina cultures was well‐described by the Monod growth equation with μmax = 1.8 d−1 and Kμ = 28 nmol P L−1. Phosphate uptake kinetics were evaluated at three growth rates and adhered to Michaelis‐Menten kinetics, with evidence of growth‐rate‐dependent variability of uptake affinities (1.9–3.0 L µmol−1 h−1) and half‐saturation constants (1.85–3.8 µmol P L−1). Maximum uptake rates were constant across growth rates when measured in either carbon‐specific (220 µmol P mol C−1 min−1), volume‐specific (7 amol P µm−3 min−1), cell‐specific (1 fmol P cell−1 min−1), or phosphorus‐specific units (7 h−1). This represents a phosphate uptake rate capacity between 200‐fold and 600‐fold greater than the requirements for growth. Finally, we compared the results from our study with previous studies across four phytoplankton species and found that the Monod half‐saturation constant for phosphorus‐limited growth (Kμ) is well‐predicted by the theoretical ratio of the maximum specific growth rate to the phosphorus‐specific uptake affinity.
Ammonium excretion by benthic invertebrates and sediment-water nitrogen flux in the Gulf of Mexico near the Mississippi River outflow

Benthic macroinvertebrate biomass and ammonium excretion rates were measured at four stations in the Gulf of Mexico near the Mississippi River mouth. Calculated areal excretion rates were then compared to sediment-water nitrogen fluxes measured in benthic bottom lander chambers at similar stations to estimate the potential importance of macroinvertebrate excretion to sediment nitrogen mineralization. Excretion rates for individual crustaceans (amphipods and decapods) was 2–21 nmoles NH4+ (mg dry weight)−1 h−1. The mean excretion rates for the polychaetes, Paraprionaspio pinnata [6–12 nmoles NH4+ (mg dry weight)−1h−1] and Magelona sp. [27–53 nmoles NH4+ (mg dry weight)−1h−1], were comparable or higher than previous measurements for similar size benthic or pelagic invertebrates incubated at the same temperature (22±1°C). Although the relatively high rates of excretion by these selective feeders may have been partially caused by experimental handling effects (e.g., removal from sediment substrates), they probably reflected the availability of nitrogen-rich food supplies in the Mississippi River plume. When the measured weight-specific rates were extrapolated to total areal biomass, areal macroinvertebrate excretion estimates ranged from 7 μmole NH4+ m−2h−1 at a 40-m deep station near the river mouth to 18 μmole NH4+ m−2h−1 at a shallower (28-m deep) station further from the river mouth. The net flux of ammonium and nitrate from the sediments to the water measured in bottom lander chambers in the same region were 15–53 μmole NH4+ m−2h−1 and −25–21 μmole NO3− m−2h−1. These results suggest that excretion of NH4+ by macroinvertebrates could be a potentially important component of benthic nitrogen regeneration in the Mississippi River plume-Gulf shelf region.
Dormancy breakage and germination are tightly controlled by hypoxic submergence water on Echinochloa crus-galli seeds from an accession resistant to anaerobic germination

Abstract In wetlands, dormancy may be a key functional trait enabling seeds to avoid underwater germination, which could be lethal for seedling establishment. Our objectives were to find out (i) if shallow dormant (i.e. conditionally dormant) Echinochloa crus-galli seeds from an anaerobic germination resistant accession can break dormancy under hypoxic submergence and (ii) if underwater germination can be restored in scarified, non-dormant seeds. Shallow dormant E. crus-galli seeds perceived diurnally alternating temperatures (AT) and red light (R) pulses (i.e. dormancy-breaking cues) under hypoxic submergence; however, an inhibitory far-red light pulse given at the end of the 4-d inundation period demonstrated that most of the seeds (85%) were unable to break dormancy. Scarified E. crus-galli seeds, which did not express dormancy under drained conditions, were unable to germinate under hypoxic submergence, despite being exposed to dormancy-breaking cues (AT + R). Lastly, the temporal window for germination sensitivity to the inhibitory action of hypoxia, once dormancy-breaking signals have been applied, is progressively lost and bounded to approximately 18 h for half of the seed lot. These results highlight the importance of dormancy as a trait enabling E. crus-galli seeds to avoid underwater germination, a risky scenario for seedling emergence and establishment in this facultative hydrophyte.
A novel method of determining the optimal polyhedral orientation for discrete global grid systems applicable to regional-scale areas of interest

ABSTRACT The polyhedral discrete global grid system (DGGS) is a multi-resolution discrete earth reference model supporting the fusion and processing of multi-source geospatial information. The orientation of the polyhedron relative to the earth is one of its key design choices, used when constructing the grid system, as the efficiency of indexing will decrease if local areas of interest extend over multiple faces of the spherical polyhedron. To date, most research has focused on global-scale applications while almost no rigorous mathematical models have been established for determining orientation parameters. In this paper, we propose a method for determining the optimal polyhedral orientation of DGGSs for areas of interest on a regional scale. The proposed method avoids splitting local or regional target areas across multiple polyhedral faces. At the same time, it effectively handles geospatial data at a global scale because of the inherent characteristics of DGGSs. Results show that the orientation determined by this method successfully guarantees that target areas are located at the center of a single polyhedral face. The orientation process determined by this novel method reduces distortions and is more adaptable to different geographical areas, scales, and base polyhedrons than those employed by existing procedures.
GENETIC VARIATION FOR FORAGE QUALITY OF ALFALFA STEMS

When normally harvested for hay, the basal portion of alfalfa (Medicago sativa L.) stems is low in forage quality. This study was conducted to determine whether genetic variation for in vitro digestible dry matter (IVDDM) and crude protein (CP) concentration of stems of perennial Medicago spp. could be identified and whether morphological and chemical traits were associated with variation in these characteristics of stems. The lower six nodes and internodes of stems and total herbage from 64 Plant Introduction (PI) accessions and five cultivars of field-grown plants were harvested twice when most plants were at the early seed-pod stage of maturity. Several morphological and growth traits were measured, and both stems and total herbage were evaluated for IVDDM and CP concentration. Covariant analysis was used to adjust in IVDDM and CP concentration of stems for differences in plant maturity. Significant variation for IVDDM and CP concentration in stems existed among the cultivars and among the accessions.
