Texto completoTouchdown Herbicide (4 LC-E) tested against tadpoles of C. insignifera, H. eyrei, L. dorsalis and L. moorei was slightly less toxic than Roundup with 48-h LC50 values ranging between 27.3 and 48.7 mg/L (9.0 and 16.1 mg/L ae). Roundup Biactive (MON 77920) was practically non-toxic to tadpoles of the same four species producing 48-h LC50 values of 911 mg/L (328 mg/L ae) for L. moorei and >1000 mg/L (>360 mg/L ae) for C. insignifera, H. eyrei and L. dorsalis. Glyphosate isopropylamine was practically non-toxic producing no mortality amongst tadpoles of any of the four species over 48 h, at concentrations between 503 and 684 mg/L (343 and 466 mg/L ae). The toxicity of technical grade glyphosate acid (48-h LC50, 81.2-121 mg/L) is likely to be due to acid intolerance. Feeding stage tadpoles of B. marinus, X laevis, C. insignifera, H.eyrei, L. dorsalis and L. moorei were exposed to NPE and alcohol alkoxylate in static renewal acute toxicity tests. All species exhibited non-specific narcosis following exposure to both these surfactants. The 48-h EC50 values for NPE ranged between 1.1 mg/L (mild narcosis) and 12.1 mg/L (full narcosis). The 48-h EC50 values for alcohol alkoxylate ranged between 5.3 mg/L (mild narcosis) and 25.4 mg/L (full narcosis). Xenopus laevis was the most sensitive species tested. The sensitivity of the other five species was size dependent with larger species displaying greater tolerance. Replicate acute toxicity tests with B. marinus exposed to NPE at 30 degrees celsius over 96 hours indicated that the narcotic effects were not particularly time dependant.
The mean 24, 48, 72 and 96-h EC50 (mild narcosis) were 3.6, 3.7, 3.5 and 3.5 mg/L respectively. The mean 24, 48, 72, and 96-h EC50 (full narcosis) values were 4.0, 4.1, 4.2 and 4.0 respectively. Acute toxicity tests with B. marinus exposed to NPE at 30 degrees celsius under conditions of low dissolved oxygen (0.8-2.3 mg/L) produced a two to threefold increase in toxicity. The 12-h EC50 values ranged from 1.4 to 2.2 mg/L. The embryotoxicity of NPE was determined in X. laevis, L. adelaidensis and C. insignifera using a Frog Embryo Teratogenesis assay-Xenopus (FETAX). The 96-h LC50, EC50 and MCIG (LOEC) values for X. laevis were 3.9 to 5.4 mg/L, 2.8 to 4.6 mg/L and 1.0 to 3.0 mg/L respectively. The 140-h LC50, ECSO and MCIG values for L. adelaidensis were 9.2 mg/L, 8.8 mg/L and 5.1 to 6.0 ing/L respectively. The 134-h LC50, EC50 and MCIG values for C. insignifera were 6.4 mg/L, 4.5 mg/L and 4.0 mg/L respectively. Teratogenicity indices for the three species ranged between 1.0 and 1.6 indicating either no or low teratogenicity. Xenopus laevis was the more sensitive of the three species and the only species that displayed indisputable terata. The acute toxicity data indicated that the amphibian species tested were of similar sensitivity to fish and some invertebrates. Developmental retardation and oestrogenic effects following exposure to nonylphenol ethoxylate were indicated by sublethal toxicity tests. Crinia insignifera embryos were exposed during early embryogenesis to sublethal concentrations of NPE.
Exposure to NPE did not affect either weight nor size (snout-vent length) at metamorphosis. Exposure to 5.0mg/L NPE resulted in a significant delay in the time required to reach metamorphosis. Also, exposure to 3.0 mg/L NPE for the first 6 days of embryonic development or exposure to 5.0 mg/L NPE from day 2 to day 6 resulted in a statistically significant predominance in the female phenotype amongst metamorphosing froglets. Exposure for the first five days to 1.5 ing/L or 3.0 mg/L NPE had no effect on sex ratio. The results indicated that exposure to NPEs has endocrine disruptive effects in this species and that a narrow window of susceptibility exists for the induction of predominantly female phenotype. This study has also followed the degradation of a mixture of NPE oligomers and the concomitant formation of individual oligomers in static die-away tests with and without illumination in freshwater. Over 33 days in darkness there was a progressive and complete loss of long chain oligomers (NPEO(subscript)8-17), transient increases and subsequent loss of short to medium chain oligomers (NPE0(subscript)4-7), and large persistent increases (approximately 1000%) in short chain oligomers (NPE0(subscript)1-3). In the presence of illumination, biodegradation was retarded and heterotrophic bacterial proliferation was inhibited. After 33 days there was complete loss of long chain oligomers (NPE0(subscript)9-17), incomplete loss of medium chain oligomers (NPE0(subscript)6.8) and increases in short chain oligomers (NPE0(subscript)1-5).
This thesis discusses the importance of persistent metabolites of NPE degradation as it pertains to the habitat, developmental time frame and ecology of amphibians. Degradation of NPE is likely to occur over a time frame that is longer than that required for complete embryogenesis and metamorphosis of many species of amphibians, and may easily encompass those critical stages of development during which oestrogenic metabolites can affect development.

Texto completo""This thesis aims to develop a better understanding of the adoptive behaviour of grain growers, through identifying socio-economic factors that influence adoption processes, and the identification of farmer typologies based upon a market segmentation approach. This study has established a clear understanding of the behavioural characteristics associated with the target population in terms of adaptive behaviour, production capabilities, information seeking characteristics and innovativeness. This study has clearly identified characteristics of agricultural knowledge systems, including the influence of information providers, the quality and credibility of information, and social influences. This study has identified a range of farming typologies on the basis of the identification of the relationships between the measured characteristics of the target population, using a series of highly robust approaches involving principal component analysis and k-means cluster analysis." -- from Abstract.

Texto completoSustainable agricultural production on drylands faces challenges from increasing food demand and climate change. The interrelated issues of production instability, vulnerability to climate change and the need for effective adaptations require a comprehensive and integrated ecological-economic assessment. Accordingly, this thesis examines two key dryland agricultural regions, the Australian Wheatbelt and the Chinese Loess Plateau, to provide new insights and improved approaches for dryland agricultural management. Decomposition analysis was undertaken to identify the driving forces in growth and instability of Australian wheat production from 1900-2010. Results show that instability of Australian wheat production has not been reduced significantly in the past century. The increasing trend of wheat production was mainly due to sowing area increases whilst the yearly fluctuation of production is mainly caused by variable yields. A focus on yield alone may therefore bias assessments of the vulnerability of agriculture to climate change. A conceptual framework was developed to assess the agricultural vulnerability of 243 rural counties on the Chinese Loess Plateau. A vulnerability index for each county was calculated from statistical indicators. Within the 49 most vulnerable counties, 42 were characterised by high exposure and sensitivity but low adaptive capacity. The most vulnerable area was found to be located in the central northeast-southwest belt of Loess Plateau. Upon identifying vulnerable areas, the effectiveness of the regionally significant adaptation, plastic film mulching, on maize growth was assessed in the Loess Plateau. The APSIM model was calibrated and validated using field experiment data, then applied to simulate maize growth during 1961-2010 at Changwu station. Plastic film mulching could significantly increase maize yields by an average of 15.3%, and increase the cumulative probability at mid-range yield levels at Changwu. The advantage was found to be more pronounced in dry years than wet years. Geostatistical analysis was used to extend the modelling across the Loess Plateau to identify areas with climate favourable for adopting plastic film mulching. The central south presented high and stable production while the northwest showed the greatest potential in yield increase and variability reduction. The multiscale studies concern both developing and developed counties, can be referenced to location-specific information for policy makers and researchers. The principles, frameworks, technologies and tools can be modified and adopted in other dryland regions.
