Abstract Exposure to extreme temperatures can negatively affect animal reproduction, by disrupting the ability of individuals produce any offspring (fertility), or number produced fertile (fecundity). This has important ecological consequences, because reproduction is ultimate measure population fitness: a reduction in reproductive output lowers growth rate and increases extinction risk. Despite this importance, there have been no large‐scale summaries evidence for effect temperature on...
Abstract Soils surrounding cattle dips in Australia are known to be highly contaminated with As and potentially of major concern the environment human health. A study 11 dip sites northern New South Wales (NSW) has revealed considerable surface soil (0–10 cm) contamination (37–3542 mg kg −1 soil). In addition it was shown that movement down through soils had occurred concentrations at 20 40 cm ranging from 57 2282 soil. At one particular site, an concentration above 14 000 determined a depth...
The most common source of elevated As concentrations in the Australian environment are attributable to anthropogenic activities. Mining activities have contributed contamination soil and water primarily Western Australia Victoria. However, other such as agriculture, forestry industry also contaminated at a localized scale. Currently there over 1000 sites previously used cattle dips for eradicating ticks. Although may be severe enough limit plant growth appears few reports identifying impacts...
Resilience can be defined as the ability of an animal to remain productive in face diverse environmental challenges. Several factors contribute animal's resilience including its resist disease, cope with climatic extremes and respond stressors. Immune competence, a proxy trait for general disease resistance, is expected resilience. This research aimed develop practical method assess immune competence Merino sheep which would not restrict future sale tested animals, estimate genetic...
A farmlet experiment was conducted between July 2000 and December 2006 as part of the Cicerone Project, which sought to enhance profitability sustainability grazing enterprises on Northern Tablelands New South Wales, Australia. self-replacing Merino enterprise grazed dominant livestock enterprise, together with ~20% carrying capacity cattle, each three treatments: higher levels soil fertility pasture renovation flexible rotational over eight paddocks (farmlet A), moderate B) intensive 37 C)....
The mediatorless electroanalytical sensing of sulfide is explored at a range commercially available graphitic based electrodes namely, edge and basal plane pyrolytic graphite (EPPGE BPPGE, respectively), boron-doped diamond (BDDE), glassy carbon (GCE) screen-printed (SPE). electrochemical performance evaluated in terms current density/analytical signal oxidation potential, where the GCE SPE are found to possess optimal responses. towards it that hampered by passivation, thus requiring...
A method has been developed for the speciation of arsenic (AsO − 2 , AsO 3− 4 and dimethylarsinic [DMA]) in natural soil solutions from contaminated sites Australia. The separation these anions was achieved by capillary zone electrophoresis (CZE) using a fused silica (72‐cm 50‐μm i.d.) with basic chromate buffer on‐column indirect UV detection at 254 nm. Method parameters, such as electrolyte pH, run voltage, temperature were studied order to establish suitable analytical conditions. ideal...
Abstract Exploratory laboratory research was performed to evaluate the fate of two organic contaminants in unsaturated zone Bandelier Tuff at Los Alamos National Laboratory chemical waste site. Studies concentrated on vapor phase diffusion for trichloroethylene and orthoxylene known occur significant amounts This undertaken support geohydrological characterization ultimately facilitate environmental transport predictions. In these diffusivity studies a method developed direct measurement...
Historically, local village, town, and county highway departments have relied heavily on the use of stone fill rock riprap to line drainage channels. These are often constructed without benefit design or evaluation alternatives, because they always been done this way. In September 1999, Munro Road reconstruction project was completed in Onondaga County, New York. As part an erosion sediment control demonstration project, portion redesigned using geosynthetic rolled products (RECPs) lieu...
With growing concerns over soil erosion and its impact on surface water quality, it is becoming increasingly important to find ways economically efficiently minimize erosion. There are a number of control methods available; however, in recent years, there has been move away from the use traditional methods, such as rock riprap, because they expensive time consuming install. This opened door for geosynthetic rolled products (RECPs.) RECPs temporary degradable or long-term non-degradable...
Evidence about the relationship between lighting and crime is mixed. Although a review of evidence found that improved road / street was associated with reductions in crime, these occurred daylight as well after dark, suggesting any effect not due only to changes visual conditions. One limitation previous studies data are reported aggregate thus analyses were required make simplifications concerning types crimes or locations. We will overcome by working UK police force access records...
In recent years, there has been a great deal of interest in the development and use natural-fiber rolled erosion control products (RECPs) to sustainably manage soil erosion. Natural fibers offer many advantages over synthetic that they are biodegradable, can absorb water, easily conform underlying surfaces. US, coir, jute, straw, wood excelsior commonly used manufacture RECPs; however, efforts being made around world (e.g. United Kingdom, Canada, US) explore potential uses other natural...
Geosynthetic rolled erosion control products (RECPs) are used extensively to minimize soil and enhance the growth of vegetation on slopes in channels. RECPs suitable for these applications come a variety different fiber structure types, ranging from coir blankets (ECBs), jute open weave textiles (OWTs), polyolefin turf reinforcement mats (TRMs). Although there is wide available, engineers often given little guidance selection beyond maximum allowable slope, velocity, shear stress. can vary...
Soil erosion by raindrop impact is an important source of soil from slopes and other non-concentrated flow areas. Vegetation one the most effective ways for minimizing impact. Ground covers, such as mulches, rock, rolled control products (RECPs) are also in reducing effects limiting amount exposed. This paper presents results a laboratory study that compares rainsplash performance 4 different RECPs (wood excelsior, coconut, jute, polypropylene (PP)), with without vegetation, using simulator....
Los anfibios han diversificado predominantemente en ambientes tropicales donde la humedad, temperatura y disponibilidad de microhábitats facilitan estabilidad demográfica. Sin embargo, múltiples linajes colonizado desiertos extremos, su diversidad es considerablemente menor. Una especie particular, el sapo Atacama (Rhinella atacamensis), se ha adaptado al Desierto Atacama, región más árida Tierra. Pese a singularidad ecológica esta especie, mayor parte los aspectos historia natural,...
A 2 year study was conducted to determine the effects of surface cover and roughness on sediment yield from plots subjected a simulated most damaging storm. This storm, based long term records 3 Wyoming streams, produced approximately 18 mm precipitation in 15 min with an intensity 97 hour(-1). The rainfall simulator covered plots; each 0.6 by m. Plots were 9% slopes highly erosive soils (silt fine sand texture) native rangeland areas Wyoming. Cover measured point frame. Sediment production...
