Moon, Katie; Institute for Applied Ecology, University of Canberra; School of Business, University of New South Wales; katieamoon@gmail.com; Brewer, Tom D.; Northern Institute, Charles Darwin University, Darwin, Northern Territory, Australia; Australian Institute of Marine Science, Arafura Timor Research Facility, Brinkin, Northern Territory, Australia; tomdbrewer@gmail.com; Adams, Vanessa M.; University of Queensland, School of Biological Sciences, Brisbane, Queensland, Australia; v.adams@uq.edu.au; Blackman, Deborah A.; School of Business, University of New South Wales; d.blackman@adfa.edu.au.
A rise in qualitative social science manuscripts published in ecology and conservation journals speaks to the growing awareness of the importance of the human dimension in maintaining and improving Earth’s ecosystems. Given the rise in the quantity of qualitative social science research published in ecology and conservation journals, it is worthwhile quantifying the extent to which this research is meeting established criteria for research design, conduct, and interpretation. Through a comprehensive review of this literature, we aimed to gather and assess data on the nature and extent of information presented on research design published qualitative research articles, which could be used to judge research quality. Our review was based on 146...

A new study method of microhabitat structure of small mammals BJB
CERQUEIRA,R.; FREITAS,S. R..
The variables in habitat studies are usually transformed in such a way that they become abstractions and intuition is lost. We tested a new method for the analysis of habitat using data collected in a grid laid at the "restinga de Maricá", in Rio de Janeiro State, Brazil. Thirty-seven microhabitat variables were measured at each trap station. We assume that these variables characterize the microhabitat structure at the moment when measurements were taken. The data are transformed in 3 ways: (1) the averages of the measured variables were calculated, as usual in habitat studies; (2) the data are transformed in densities per area in square meters without reduction in the number of variables; and (3) we calculated the natural logarithms of the data thus...

A simple and rapid method for collecting saliva to assess sodium status in sheepum Ciência Rural
Ortolani,Enrico Lippi.
Fifteen lambs were fed diet with normal (0.11%) or deficient levels of sodium ( 0.035%), respectively, for five weeks on each diet. At the end of each period saliva was collected by three different methods: swabbing with a 5 x 5 x 1.25cm synthetic sponge, aspiration with a 15cm long plastic tube connected to a 20ml syringe and sucking with a 4mm x 45cm long plastic tube through a water-jet aspirator pump or an eletric motor pump. The volume of saliva collected/min and the salivary sodium: potassium ratio were analysed. Larger volume of saliva was obtained with the developed sucking apparatus than with the sponge or the syringe. There was no influence of the method of saliva collection on the values of salivary Na:K ratio in both periods. Nevertheless, the...

Accounting for Heterogeneity in Hedging Behavior: Comparing & Evaluating Grouping Methods AgEcon
Pennings, Joost M.E.; Garcia, Philip; Irwin, Scott H..
Heterogeneity, i.e., the notion that individuals respond differently to economic stimuli, can have profound consequences for the interpretation of behavior and the formulation of agricultural policy. This paper compares and evaluates three grouping techniques that can be used to account for heterogeneity in financial behavior. Two are well established: company-type grouping and cluster analysis. A third, the generalized mixture regression model, has recently been developed and is worth considering as market participants are grouped such that their response to the determinants of economic behavior is similar. We evaluate the grouping methods in a hedging framework by assessing their ability to reflect relationships consistent with theory. The empirical...

An analysis of seafood consumption survey methods in France. ArchiMer
Girard, Sophie; Mariojouls, Catherine; Paquotte, Philippe; Wisner-bourgeois, Claude.
(Not controled OCR) The different statistical data sources available for seafood I consumption analysis in France belong to three types : the apparent consumption estimated on the basis of a balance between production and trade, used at national scale and for international comparison, the data in value published by the national Institute for economic statistics, aggregating food balance sheet, and economic results of inquiries about the activities of the branch industries, and the household consumption estimated through consumers' panels. A critical and historical analysis of the different available data series is presented, with focus on the major difficulties when interpreting and cross-checking the data (series breaking-nomenclature items, range of...

Capture sequence and relative abundance of bats during surveys Rev. Bras. Zool.
Esbérard,Carlos E. L..
It is expected that rare species will be gradually added to biodiversity surveys over time and that complete inventories will include rare species. The objective in the present work is to test whether the capture sequence of species during a bat survey is related to species abundance. Species with capture rates lower than 0.01x10-3 captures/hour-net were considered rare. At Ilha da Gipóia, rare species accounted for 22.22% of the total and, at Rio das Pedras Reserve, they represented 30.00%. The existence of a negative relationship between the relative abundance and the first night of capture of each species for the Ilha da Gipóia and the high significance level for the accumulation curve at both localities suggest that the documentation of a large number...

Comparaison de méthodes d'évaluation de la production secondaire d'une population de l'annélide polychète Ditrupa arietina (O.F. Muller) ArchiMer
Medernach, L; Gremare, A.
We compared the ability of three direct methods (increment summation, loss summation and instantaneous growth rate coefficient), the size-frequency method, and eight indirect methods (Banse and Mosher, Benke, Brey, Edgar, Morin and Bourassa, Plante and Downing, Robertson and Schwinghamer et al.) to measure or to predict the secondary production of a Mediterranean population of the polychaete Ditrupa arietina. This comparison was carried out both on the 1994 cohort during its two-year lifespan and on the entire population during the two years of the study (1994-1996). Our results showed that all three direct methods are more or less equivalent. Results referring to the year 1994-1995 showed a strong overestimation of the actual production by the size...

Comparison of methodologies for moisture determination on dried bee pollen samples Ciênc. Tecnol. Aliment.
Melo,Illana Louise Pereira de; Almeida-Muradian,Ligia Bicudo de.
Bee pollen moisture value is one of the quality parameters for this product. Some countries such as Argentina, Brazil, Bulgaria, Poland and Switzerland have bee pollen regulations on quality parameters, but these are not clear regarding which method should be used for moisture determination. The aim of this paper was to compare six methods of moisture determination in dried bee pollen samples. The methods were: conventional oven at 100 °C, vacuum oven at 70 °C, desiccator with sulfuric acid, drying out process with infrared light at 85 °C, lyophilization and Karl Fisher's method. Based on the results, the best methods for moisture determination of bee pollen were the drying process with infrared and the lyophilization, since these have shown lower moisture...

COMPARISON OF METHODS FOR ESTIMATING REFERENCE EVAPOTRANSPIRATION: AN APPROACH TO THE MANAGEMENT OF WATER RESOURCES WITHIN AN EXPERIMENTAL BASIN IN THE BRAZILIAN CERRADO REA
Gotardo,Jackeline T.; Rodrigues,Lineu N.; Gomes,Benedito M..
ABSTRACT This study aimed to compare methods for estimating reference evapotranspiration using an experimental basin in the Brazilian Cerrado, for water management purposes. For that, we estimated daily reference evapotranspiration over a certain period (time series between 1982 and 2012) through different empirical methods. These methods consisted of Blaney-Criddle (BC), Hargreaves & Samani (HS), ASCE Penman-Monteith (ASCE- PM), Penman (1948/1963) (PO), Priestley-Taylor (PT), which were all compared to the standard Penman-Monteith FAO-56 (PM-FAO56). Based on statistics, ASCE- PM, P and BC methods should be recommended for cerrado areas, either in rainy or dry seasons. After these, the PT also stood out. Among the less complex methods, based on...

Conservation des laminaires apres sechage a tres hautes temperatures. ArchiMer
Perez, René.
Laminaria digitata is the only brown alga used in the French alginate industry. Air-dried and flash-dried (in a current of air at 200 to 850 degree C) algae were compared. Quality was assessed viscometrically and the results expressed graphically. Quality after drying and keeping properties were found better in flash-dried algae and the method was shown to be the cheapest of methods currently available.

Control of ammonia emissions in naturally ventilated dairy cattle facilities in Portugal REA
Pereira,José; Trindade,Henrique.
We conducted a study of the processes associated to NH3 emission in naturally ventilated dairy cattle facilities, having described factors that regulate NH3 emission, as well as methodologies for measuring these emissions at these facilities. Appropriate techniques to mitigate NH3 emission in facilities located in regions with warm climates were also identified. The most effective mitigation techniques with simple implementation include strategies associated to: (i) installation design and flooring, which lead to reduced emissions, (ii) excreta pre-excretion, namely the use of diets with optimized crude protein content and increased milk production at farm level; and (iii) excreta post-excretion, particularly by changing the conditions of environmental...

Efeitos fixos ou aleatórios de repetições no contexto dos modelos mistos no melhoramento de plantas perenes. Infoteca-e
RESENDE, M. D. V. de.
A estimação de componentes de variância e a predição de valores genéticos no contexto do melhoramento de plantas perenes, demanda o uso da metodologia de mode los mistos (REML/BLUP) ao nível individual, a qual vem sendo aplicada com eficiência ao melhoramento de várias espécies perenes. Uma questão fundamental na aplicação dessa metodologia refere-se à definição dos efeitos do modelo estatístico como fixos ou aleatórios. No caso do efeito de repetições experimentais esta definiçâo nem sempre é trivial. Assim, esta questão é abordada no presente artigo.

Estrogen Receptors in Immunohistochemically Stained Slides: Comparing Subjective and Computerized Evaluation Methods International Journal of Morphology
Millas,Ieda; Barros,Mirna Duarte; Curcio,Daniella Franco; Buck,Hudson Sousa; Liquidato,Bianca Maria.
Immunohistochemistry is a specific and sensitive staining method for detection of several proteins. One important function of this method is to help us on the diagnosis of the presence of specific receptors as the estrogen receptors. The aim of this study was to compare two different methods to evaluate immunohistochemical staining intensity to detect the presence of ER in the nasal mucosa tissue: one using a digital system and the other through conventional direct microscopy observation. Sixty two stained samples were observed and analyzed under optic microscopy by three specialized professionals, who have graded intensity from: absent, mild, moderate and intense staining. Afterwards, an objective measurement was obtained by a relative optical density...
