Indirect contributions of forests to dietary diversity in Southern Ethiopia
Baudron, Frédéric

Remans, Roseline

Sunderland, Terry
We assess whether forests contribute indirectly to the dietary diversity of rural households by supporting diverse agricultural production systems. We applied our study in a landscape mosaic in Southern Ethiopia that was divided into three zones of increasing distance to Munesa Forest—“near,” “intermediate,” and “distant.” A variety of research tools and methods, including remote sensing, participatory methods, farm survey, and yield assessment, were employed. Diets of households were more diverse in the near zone than in the other two zones (6.58 ± 1.21, 5.38 ± 1.02, and 4.41 ± 0.77 food groups consumed daily in the near, intermediate, and distant zones, respectively). This difference was not explained by food items collected from Munesa Forest but by biomass flows from the forest to farmlands. Munesa Forest contributed an average of 6.13 ± 2.90 tons of biomass per farm and per year to the farms in the near zone, in the form of feed and fuelwood. Feed from the forest allowed for larger livestock herds in the near zone compared with the other two zones, and fuelwood from the forest reduced the need to use cattle dung as fuel in the near zone compared with the two other zones. These two biomass flows contributed to the availability of more manure to farmers closer to the forest (908 ± 853 kg farm -1 , 771 ± 717 kg farm -1 , and 261 ± 487 kg farm -1 in the near, intermediate, and distant zones, respectively). In turn, increased manure enabled a larger percentage of farms to cultivate a diversified homegarden (87, 64, and 39% of farms in the near, intermediate, and distant zones, respectively). Homegardens and livestock products provided the greater contribution to household dietary diversity closer to the forest.

Researching immunocontraceptive vaccines with mares (Equus caballus) as both a target and model for African elephant (Loxodonta africana) cows: a review
Joonè, Carolynne L.
Nolan, Margaret B.
Bertschinger, Henk J.
Schulman, Martin L.
A sequence of studies is reviewed that reported the domestic horse (Equus caballus) mare as an appropriate and accessible research platform for recording clinical and laboratory data post-immunisation with anti- GnRH and -zona pellucida (ZP) immunocontraceptive vaccines. Experience with a native porcine ZP (pZP) vaccine in African elephant (Loxodonta africana) cows highlighted needs for improving vaccine formulations and more clearly defining associated ovarian effects and safety profiles. Initially, the efficacy, reversibility and safety of the GnRH vaccine Improvac® in mares was demonstrated using reproductive tract ultrasonography and concurrently measuring serum antibody titres and progesterone concentrations. Results informed the study design and minimally invasive monitoring of post-treatment ovarian steroid responses of this vaccine in free-ranging African elephant cows. A subsequent sequence of studies reported reversible contraceptive and immunological efficacy in pony mares immunised with pZP formulated with Freund’s adjuvants. By comparison, mares treated with a recombinant ZP3 and ZP4 (reZP) vaccine showed disappointing responses. Unexpectedly, most pZP-treated mares showed ovarian inactivity. In attempting to understand this response, results showed the involvement of cytotoxic (CD8+) T-cells negatively correlated to serum ovarian steroid and anti-Müllerian hormone (AMH) levels. Of concern was the prevalence of injection-site lesions ascribable to Freund’s adjuvants. Following this, mares treated with both pZP and a novel reZP vaccine formulated with non-Freund’s adjuvants showed comparable immunological responses and ovarian inactivity, notably without adverse treatment reactions. In addition, measuring AMH showed promise for monitoring ovarian function in anti-ZP-treated animals.

Investigating the identification of atypical sugarcane using NIR analysis of online mill data
Sexton, Justin
Everingham, Yvette
Donald, David
Staunton, Steve
White, Ronald
In any given season thousands of tonnes of sugarcane with atypically low quality can pass undocumented through Australian sugarcane mills. Sugarcane with atypically low quality can negatively impact mill processes and throw off grower payment calculations. Mill laboratory operators often observe a small subset (1 similar to 5%) of cane consignments that have an unusually low juice Pol (Pij; a measure of sucrose content) relative to juice brix (Bij; a measure of dissolved sugars), that can indicate deteriorated or contaminated cane. Many mills only test a small subset of cane in the laboratory, with the majority of consignments analysed using fast near infrared (NIR) spectroscopic techniques. This means the true extent of 'atypical! consignments cannot be identified. To address this limitation, this paper compares five modelling approaches: Linear discriminant analysis (LDA), partial least squares discriminant analysis (PLS-DA), random forest (RF), Artificial Neural Networks (ANN) and Support Vector Machines (SVM). Model performance was reported as the correct classification rate (CCR) of typical and atypical samples based on independent test sets. The best performance was achieved by PLS-DA (CCRtypical = 88.65% and CCRtypical = 88.75%), while ANN had the lowest performance (CCRatypical = 85.27% and CCRtypical = 83.66%). The methodology used in this paper could be used to identify atypical consignments allowing mills to track occurrences to farms and if necessary develop process control operations for atypical cane. Furthermore, the use of a relatively simple modelling technique such as PLS-DA means model updates can be made efficiently and with confidence as PLS is already well established within the industry.

Traits for canopy development and light interception by twenty-seven Brazilian sugarcane varieties
Dias, Henrique Boriolo

Everingham, Yvette
Sentelhas, Paulo Cesar
Bermejo, Rodrigo
Christodoulou, Diomedes
Since new varieties are released continuously in the Brazilian sugarcane agro-industry, the understanding of their growth, development and yields are necessary. In Brazil, there is a lack of studies on sugarcane variety traits for canopy development and yields, especially those employed by the sugarcane modelling community. This paper assessed the canopy development and light interception by 27 sugarcane varieties grown at two tropical sites (Sao Romao, MG, and Guadalupe, PI) under non-limiting (potential) conditions in Brazil and tested the capability of the well-known APSIM-Sugar model to distinguish these varieties.
Parameters for APSIM-Sugar canopy traits (leaf size, green leaf number, tillering and stalk emergence) and the light extinction coefficient were derived for each variety from field experiments and by calibration for the plant cane cycle. Trait parameters were then validated satisfactorily against independent datasets from the same two sites (first racoon cycle of 27 varieties) and a row spacing experiment at Sao Romao (plant and racoon for six varieties). A validation was also done using published experiments in other five sites across Brazil (four varieties).
After APSIM-Sugar parameters were calibrated and validated, long-term simulations were run for each variety at the two sites. APSIM-Sugar outputs of thermal time to reach 50% of canopy closure were employed to group the varieties in terms of canopy formation by clustering analysis. The four major clusters corresponded well with promotional information from breeding companies in Brazil about canopy formation.
These findings suggest it is reasonable to hypothesise that the APSIM-Sugar parameters are plausible and are an important step for unravelling genetic x environment x management interactions to improve yields and quality in the Brazilian sugarcane agro-industry.

On the joint calibration of multivariate seasonal climate forecasts from GCMs
Schepen, Andrew
Everingham, Yvette
Wang, Quan
Multivariate seasonal climate forecasts are increasingly required for quantitative modeling in support of natural resources management and agriculture. GCM forecasts typically require postprocessing to reduce biases and improve reliability; however, current seasonal postprocessing methods often ignore multivariate dependence. In low-dimensional settings, fully parametric methods may sufficiently model intervariable covariance. On the other hand, empirical ensemble reordering techniques can inject desired multivariate dependence in ensembles from template data after univariate postprocessing. To investigate the best approach for seasonal forecasting, this study develops and tests several strategies for calibrating seasonal GCM forecasts of rainfall, minimum temperature, and maximum temperature with intervariable dependence: 1) simultaneous calibration of multiple climate variables using the Bayesian joint probability modeling approach; 2) univariate BJP calibration coupled with an ensemble reordering method (the Schaake shuffle); and 3) transformation-based quantile mapping, which borrows intervariable dependence from the raw forecasts. Applied to Australian seasonal forecasts from the ECMWF System4 model, univariate calibration paired with empirical ensemble reordering performs best in terms of univariate and multivariate forecast verification metrics, including the energy and variogram scores. However, the performance of empirical ensemble reordering using the Schaake shuffle is influenced by the selection of historical data in constructing a dependence template. Direct multivariate calibration is the second-best method, with its far superior performance in in-sample testing vanishing in cross validation, likely because of insufficient data relative to the number of parameters. The continued development of multivariate forecast calibration methods will support the uptake of seasonal climate forecasts in complex application domains such as agriculture and hydrology.

An improved workflow for calibration and downscaling of GCM climate forecasts for agricultural applications – a case study on prediction of sugarcane yield in Australia
Schepen, Andrew
Everingham, Yvette
Wang, Quan
Seasonal climate forecasts can improve the accuracy of early-season estimates of crop yield and influence seasonal crop management decisions. Climate forecasting centres around the globe now routinely run global climate models (GCMs) to provide ensemble forecasts. However, raw GCM forecasts require post-processing to improve their reliability and to enable systematic integration with crop models. Post-processing to meet crop model input requirements is highly challenging and simple bias-correction methods can perform poorly in this regard. As a result of the difficulties, GCM forecasts are often sidelined in favour of other inputs such as climate analogues. In this study, we evaluate two variants of a recently-developed post-processing method designed to systematically and reliably calibrate and downscale GCM forecasts for use in crop models. In one variant, local GCM forecasts of rainfall, temperature and solar radiation are post-processed directly. The second variant is a novel adaption in which the predictive input is instead the GCM's forecast of a large-scale climate pattern, in this case related to the El Nino-Southern Oscillation. The post-processed climate forecasts, which are in the form of ensemble time series, are used to drive an APSIM-sugar model to generate long-lead forecasts of biomass in north-eastern Australia from 1982 to 2016. A rigorous probabilistic assessment of forecast attributes suggests that local GCM forecast calibration provides the most skilful forecasts overall although the ENSO-related forecasts give more skilful biomass forecasts at certain times, implying model combination could be worthwhile to maximise skill. The generated biomass forecasts are unbiased and reliable for short to long lead times, suggesting that the downscaling methods will be of value to trial in a range of crop forecast applications, and support the quantitative, meaningful use of GCM forecasts in agriculture.

The role of Landcare group networks in rural Australia: exploring the contribution of social capital
Sobels, Jonathon
Curtis, Allan
Lockie, Stewart
In this paper, the authors report their qualitative research examining the origins, modus operandi and outcomes of two networks. The concept of social capital explains, at least in part, the apparent success of these networks. The two networks attracted substantial funding, created opportunities for participation and shared learning, carried out extensive on-ground works, improved communication structures, adopted more professional management practices and increased the knowledge of members. The key elements of social capital that were important in achieving these outcomes were trust, norms, expectations of reciprocity and linkages. Empowerment acted as a bridge that linked social capital with other factors contributing to network outcomes. The success of these Landcare networks suggests that top-down government stimulus can be a catalyst for bottom-up community development.

A review of welfare indicators for sea turtles undergoing rehabilitation, with emphasis on environmental enrichment

For animals undergoing rehabilitation it is vital to monitor welfare in a way that is feasible, practical, and limits stress to the animal. The industry gold standard is to assess welfare under the Five Domains model, including nutrition, environment, physical health, and behaviour as the first four physical domains and mental domain as the fifth. Feasibility and effectiveness of these domains for assessing welfare of sea turtles undergoing rehabilitation were reviewed and it was determined that the mental state can be best assessed through behavioural changes. A scoping review of the literature was conducted using Scopus and Web of Science to investigate use of environmental enrichment devices (EEDs) as a measure of welfare in sea turtles. Behavioural assessments using EEDs were found to be well-documented; however, most EED studies pertained largely to livestock or zoo animals. Furthermore, studies rarely concentrated on reptiles, and specifically sea turtles. Results also showed that some welfare assessment methods may be less appropriate for short-term captivity experienced during rehabilitation. Additionally, the hospital environment limits the ability to address some of the domains (ie biosecurity, feasibility, safety of turtle, etc might be compromised). This review shows that only three of the nine environmental enrichment strategies described in the literature suit the specific requirements of sea turtles in rehabilitation: feeding, tactile, and structural. It is documented that turtles display behaviours that would benefit from EEDs and, therefore, more specific studies are needed to ensure the best welfare outcomes for sea turtles undergoing rehabilitation.

Reports of toxic algae-related fish kills are on the rise. Toxic algae may predispose to secondary infectious disease or poor growth, and have a significant impact on aquaculture (Andersen et al., 2016; Noga, 1998; Place et al., 2012). This case was presented for investigation into persistent low-grade mortality in red snapper, Lutjanus species Bloch, which did not respond to several therapeutic interventions. Histopathological examinations suggest exposure to toxic

Rediscovering wild food to diversify production across Australia's agricultural landscapes
Canning, Adam D.
Conventional agriculture currently relies on the intensive and expansive growth of a small number of monocultures, this is both risky for food security and is causing substantial environmental degradation. Crops are typically grown far from their native origins, enduring climates, pests, and diseases that they have little evolutionary adaptation to. As a result, farming practices involve modifying the environment to suit the crop, often via practices including vegetation clearing, drainage, irrigation, tilling, and the application of fertilizers, pesticides, and herbicides. One avenue for improvement, however, is the diversification of monoculture agricultural systems with traditional foods native to the area. Native foods benefit from evolutionary history, enabling adaptation to local environmental conditions, reducing the need for environmental modifications and external inputs. Traditional use of native foods in Australia has a rich history, yet the commercial production of native foods remains small compared with conventional crops, such as wheat, barley and sugarcane. Identifying what native crops can grow where would be a first step in scoping potential native food industries and supporting farmers seeking to diversify their cropping. In this study, I modeled the potentially suitable distributions of 177 native food and forage species across Australia, given their climate and soil preferences. The coastal areas of Queensland's wet tropics, south-east Queensland, New South Wales, and Victoria were predicted to support the greatest diversity of native food and forage species (as high 80–120 species). These areas also correspond to the nation's most agriculturally intensive areas, including much of the Murray-Darling Basin, suggesting high potential for the diversification of existing intensive monocultures. Native crops with the most expansive potential distribution include Acacia trees, Maloga bean, bush plum, Emu apple, native millet, and bush tomatoes, with these crops largely being tolerant of vast areas of semi-arid conditions. In addition to greater food security, if diverse native cropping results in greater ecosystem service provisioning, through carbon storage, reduced water usage, reduced nutrient runoff, or greater habitat provision, then payment for ecosystem service schemes could also provide supplemental farm income.

The haematology of clinically healthy, farmed juvenile Asian seabass (Lates calcarifer Bloch)-reference intervals, and indicators of subclinical disease
Chew, Xian Zhe
Gibson-Kueh, Susan
This study establishes the blood reference intervals (RIs) for clinically healthy and farmed juvenile Asian seabass (Lates calcarifer), within 4-6 weeks after stocking into flow-through, marine aquaculture systems. The 90% percentile RIs (n = 156, mean bodyweight 41.8 g) are as follows: glucose (GLU) 2.4-11.3 mmol/L, haematocrit (Hct) 18.9%-39.2%, haemoglobin concentration (Hb) 56.0-85.0 g/L, total plasma protein (TPP) 56.0-77.0 g/L, total red blood cell (RBC) count 4.1-11.2 × 1012 /L, total white blood cell (WBC) count 5.3-69.9 × 109 /L, total lymphocytes 4.7-51.4 × 109 /L, monocytes 0.3-16.2 × 109 /L and heterophils count 0.6-8.4 × 109 /L. Pearson's method analysis showed weak but significantly positive correlations between fish bodyweight and Hct, Hb, TPP and total RBC count (p < 0.05). Histopathology of 42 of the 156 clinically healthy fish used to derive the RIs, with blood values within the 90% percentile range, did not exhibit any abnormal pathology. In contrast, histopathology from a different group of clinically healthy L. calcarifer (n = 72, mean bodyweight 31.3 g) with blood values falling outside of these established 90% percentile RIs showed that 25% of these fish had severe, chronic granulomatous enteritis, and 13% had severely depleted lipid stores in their liver. Point biserial correlation analysis of blood values from this second group of 72 fish showed that elevated total WBC, monocyte and heterophil counts and reduced Hct levels are significantly associated (p < 0.05) with the occurrence of severe, chronic granulomatous enteritis and depleted lipid stores in their liver. Reduced blood GLU and TPP levels in the second group of fish were significantly associated with fish that had depleted lipid stores in liver (p < 0.05), corroborating a period of malnutrition. This study is among the first to establish blood RIs for clinically healthy, farmed juvenile L. calcarifer and detection of subclinical diseases in fish to support early intervention.

Four putative aquabirnaviruses, based on morphology, nucleic acid type and partial RNA-dependent RNA polymerase gene (VP1) sequence, isolated from three tropical freshwater fish species were not neutralised by antisera against type members of the Aquabirnavirus genus serogroups A, B or C. Antisera produced against two of the isolates neutralised the homologous and heterologous isolates, but not any type member of Aquabirnavirus serogroups A, B or C. The serological comparisons suggest that the four isolates should be regarded as members of a fourth Aquabirnavirus serogroup, D.
