Due to climate change, forests are likely to face new hazards, which may require adaptation of our existing silvicultural practices. However, it is difficult to imagine a forest management approach that can simultaneously minimize all risks of damage. Multicriteria decision analysis (MCDA) has been developed to help decision makers choose between actions that require reaching a compromise among criteria of different weights. We adapted this method and produced a multicriteria risk analysis (MCRA) to compare the risk of damage associated with various forest management systems with a range of management intensity. The objective was to evaluate the effect of four forest management alternatives (FMAs) (i.e., close to nature, extensive management with combined...

A multi-period positive mathematical programming approach for assessing economic impact of drought in the Murray-Darling Basin, Australia AgEcon
Qureshi, Muhammad Ejaz; Ahmad, Mobin-ud-Din; Whitten, Stuart M.; Kirby, Mac.
In the last decade, the Murray-Darling Basin (MDB), Australia faced a severe drought which affected its agriculture production. Sustainable diversion limits as proposed in the Australian Government’s basin plan together with climate change is expected to impact on future agriculture production and development in the MDB. We developed a biophysical-economic mathematical model calibrated against the observed multi-period land use data utilising the positive mathematical programming (PMP) approach to evaluate the impacts on agricultural production activities of a range of climate events and policy options. This is an extension of our previous work where the model was calibrated against a single year and focus was on the southern MDB only. The multi-period...

A new concept for the control of Elytrigia repens in organic crop production Organic Eprints
Melander, Bo; Nørremark, Michael; Fløjgaard, Erik.
The control of perennial weeds in organic crop production needs reconsideration to minimise losses of nutrients through leaching. Long post-harvest periods with mechanical weed control hinder a plant cover with the purpose of taking up nutrients not being utilised by the main crop to maintain soil fertility. To meet the interests of nutrient and weed management, we suggest a new concept for the control of perennial weeds with propagules placed within the plough layer. The concept comprises uprooting and immediate removal of Elytrigia repens rhizomes with modified machinery to allow for a quick re-establishment of a plant cover to avoid longer periods of bare soil. Four passes with a modified cultivator where each pass was followed by rhizome removal and...

A New Method for Characterization of Natural Zeolites and Organic Nanostructure using Atomic Force Microscopy Nature Precedings
Domenico P. R. O. F. Fuoco.
In order to study and develop an economic solution to environmental pollution in water, a wide variety of materials were investigated. Natural zeolites emerge from that research as the best in class of this category. Zeolites are natural materials relatively abundant and non biodegradable, economic and good to perform processes of environmental remediation. This paper contains a full description of a new method to characterize superficial properties of natural zeolites of exotic provenience (Caribbean Islets) with atomic force microscopy (AFM). AFM works with the optical microscope simplicity and the high resolution typical of a transmission electron microscope (TEM). Structural information of mesoporous material is obtained using scanning and transmission...

A new outlook towards kidney injuries Nature Precedings
Mahesh Satwekar; Abhijeet Satwekar.
Acute and chronic progression of injury to the kidney leads to the failure of the renal system and has become an increasingly important cause of morbidity and mortality. Present diagnosis detects the condition only after irreversible loss of 70 percent of kidney function. Current research is focused only on the clinical manifestations after the kidney injuries and not towards the exact cause of the condition. Here we propose a new outlook- that there is an involvement of a pathogen in the pathogenesis of kidney injuries. Basis for our proposal is given by the similarity of the pathogenesis events occurring between a classical example of hepatitis and kidney injuries. Furthermore, literature regarding the role of early kidney injury biomarkers in innate...

A new single nucleotide polymorphism in the ryanodine gene of chicken skeletal muscle. Repositório Alice
DROVAL, A. A.; BINNECK, E.; MARIN, S. R. R.; PAIÃO, F. G.; OBA, A.; NEPOMUCENO, A. L.; SHIMOKOMAKI, M..
Some genes affect meat quality in chickens. We looked for polymorphisms in the Gallus gallus α-RyR gene (homologous to RyR 1) that could be associated with PSE (pale, soft and exudative) meat. Because RyR genes are over 100,000 bp long and code for proteins with about 5000 amino acids, primers were designed to amplify a fragment of hotspot region 2, a region with a high density of mutations in other species. Total blood DNA was extracted from 50 birds, 25 that had PSE meat and 25 normal chickens. The DNA samples were amplified by PCR, cloned, sequenced, and used to identify single nucleotide polymorphisms (SNPs). The amplified fragment of α-RyR was 604 nucleotides in length; 181 nucleotides were similar to two exons from a hypothetical...

A new species of Asplenium section Thamnopteris (Aspleniaceae) from Indonesia Naturalis
Dong, S.Y.; Mujahidin; Wei, L.L.; Chao, Y.S..
A new species, Asplenium riswanii (sect. Thamnopteris), is described from Central Java and West Papua, Indonesia. It is distinct from any known species by having thick and rigid fronds, abaxially keeled midribs, broadly lanceolate scales, and distantly spaced sori. Morphologically, A. riswanii is not similar to any species from Malesia but somewhat close to A. antrophyoides from mainland Southeast Asia. Molecular data reveal it has an isolated position in the phylogeny. The micromorphology of spores and leaf epidermis of A. riswanii is also documented and a key to the species of Asplenium sect. Thamnopteris from Malesia is given.

A NEW WORLD MONKEY MICROSATELLITE (AP74) HIGHLY CONSERVED IN PRIMATES Acta biol.Colomb.
OKLANDER,LUCIANA INÉS; STEINBERG3,ELIANA RUTH; DOLORES MUDRY,MARTA.
Given their great variability, microsatellites or STRs became the most commonly used genetic markers over the last 15 years. The analysis of these markers requires minimum quantities of DNA, allowing the use of non invasive samples, such as feces or hair. We amplified the microsatellite Ap74 in blood and hair samples in order to analyze the levels of genomic conservation among a wide range of primates including: Lemur catta, Alouatta caraya, Ateles belzebuth, Ateles chamek, Pan troglodytes, Papio sp., and Homo sapiens. In all cases we obtained amplification products that exhibited similar size both in monkeys and human (oscillating between 126 and 176 bp), except in the lemur where the detected fragment presented a size of approximately 1000 bp. The...

A Non-Parametric Analysis of Rice Production Efficiency in Sri Lanka AgEcon
Thibbotuwawa, Manoj; Mugera, Amin W.; White, Benedict.
This article investigates the production efficiency of rice farming in Sri Lanka using cross section survey data of 90 farms. Past studies on rice farming have mostly focused on technical efficiency (TE). Here, we examine technical efficiency, allocative efficiency (AE) and cost efficiency (CE) using the data envelopment analysis (DEA) approach. On average, the farms were 87% technically efficient; irrigated farms were more efficient (88%) than rain-fed farms (82%). Average cost, allocative and scale efficiencies were 73%, 84% and 87%. Bias corrected TE estimate suggests an expected output expansion of 25% with a given input combination in order to become fully efficient as opposed to 16% based on the original estimates. In addition, a second stage Tobit...

A non-parametric indicator Kriging method for generating coastal sediment type map. OceanDocs
Liu, Fucheng; Peng, Jun; Zhang, Cunyong.
Coastal sediment type map has been widely used in marine economic and engineering activities, but the traditional mapping methods had some limitations due to their intrinsic assumption or subjectivity. In this paper, a non-parametric indicator Kriging method has been proposed for generating coastal sediment map. The method can effectively avoid mapping subjectivity, has no special requirements for the sample data to meet second-order stationary or normal distribution, and can also provide useful information on the quantitative evaluation of mapping uncertainty. The application of the method in the southern sea area of Lianyungang showed that much more convincing mapping results could be obtained compared with the traditional methods such as IDW, Kriging...

A nonsense mutation in the tyrosinase gene causes albinism in water buffalo. Repositório Alice
DAME, M. C. F.; XAVIER, G. M.; OLIVEIRA FILHO, J. P.; BORGES, A. S.; OLIVEIRA, H. N.; RIET-CORREA, F.; SCHILD, A. L..
Background: Oculocutaneous albinism (OCA) is an autosomal recessive hereditary pigmentation disorder affecting humans and several other animal species. Oculocutaneous albinism was studied in a herd of Murrah buffalo to determine the clinical presentation and genetic basis of albinism in this species. Results: Clinical examinations and pedigree analysis were performed in an affected herd, and wild-type and OCA tyrosinase mRNA sequences were obtained. The main clinical findings were photophobia and a lack of pigmentation of the hair, skin, horns, hooves, mucosa, and iris. The results of segregation analysis suggest that this disease is acquired through recessive inheritance. In the OCA buffalo, a single-base substitution was detected at nucleotide 1,431 (G...

A Note On The Denisova Cave mtDNA Sequence Nature Precedings
Niccolo Caldararo; Michael Guthrie.
The recently published Altai fossil sequence from Denisova Cave was purported to be so different from anatomically modern humans, yet have the physiological landmarks of that species designation. When the published sequence was examined it was found that segments in the mtDNA hypervariable regions could be found to align with that of anatomically modern humans if one introduced an insertion at a position found in Neanderthals. Some other points of interest arise from a reconsideration of the sequences for other published samples and Neanderthals from the same perspective.
