Resumen

A study was made of the germination characteristics of a broad spectrum of rangeland species by studying their behaviour under different conditions. Seeds of common species (both native and exotic) were collected from tropical (north-east Queensland) (36 species) and sub-tropical areas (south-east Queensland) (47 species). The seeds were exposed to three storage treatments: in a shade-house for 60 months, in a seed store (tropical collection) or freezer (sub-tropical collection) for 60 months, or in an oven with fluctuating temperatures (25/60°C) for 3 (tropical collection) or 4 (sub-tropical collection) months. Germination was tested during and after storage under standard conditions of 30/25°C (tropical collection) or 30/20°C (sub-tropical collection) with light during the 12-h period of higher temperature. In addition, germination of the sub-tropical collection was tested in the dark and at lower temperature (20/10°C). The species were divided into groups on the basis of changes in germination during storage in a shade-house or in a seed store or freezer. The species showed a wide range of germination behaviour, changes during storage, and responses to germination conditions. Differences in the responses of seed lots of the same species in the two collections show that care is needed when extrapolating results from one experiment to other collections and regions.

Resumen

Salmonellosis is an important cause of morbidity in tropical regions.This study aims to describe the epidemiology of non-typhoidal Salmonellae (NTS) in children presenting to public hospitals in Queensland, Australia, over the past 20 years, with a focus on differences between tropical and sub-tropical zones in the region. This is a retrospective and descriptive cohort study of 8162 NTS positive samples collected in 0–17-year-olds from the Queensland public hospital pathology database (Auslab) over a 20-year period from 1997 to 2016. There were 2951 (36.2%) positive NTS samples collected in tropical zones and 5211 (63.8%) in the sub-tropical zones of Queensland, with a total of 8162 over the region. The tropical zone contributed a disproportionately higher number of positive NTS samples by population sub-analysis. Of the specimens collected, 7421 (90.92%) were faecal, 505 (6.2%) blood, 161 (1.97%) urine, 13 (0.16%) cerebrospinal fluid (CSF) and 62 of other origin. Other categories of specimen types isolated include swab, fluid, aspirate, lavage, bone, tissue, isolate and pus, and these were not included in sub-analysis. The most commonly identified serovars were Salmonella Typhimurium, Salmonella Virchow and Salmonella Saintpaul. This is the first and largest study that emphasises the high burden of invasive and non-invasive NTS infections resulting in hospital presentations in the paediatric population of tropical north Queensland, compared to the sub-tropics.

Resumen

Clonal variation in morphological growth parameters of Populus deltoides and P. ciliata were studied in the nursery stages in Sub-tropical (Naganji) and Sub-temperate (Shilli) regions to assess their planting success and growth potential in their climatic zones. P. deltoides clones planted in Sub-tropical nursery recorded highest average height (298.70cm), basal diameter (21.75mm) and leaf area (175.40cm2) with clone ‘PD-1’ sharing maximum height (350.00± 26.07cm) and leaf area (193.70±6.86cm2). Whereas, basal diameter was recorded maximum in the clone ‘G-48’ (25.05±3.77mm). Among P. ciliata clones planted under Sub-temperate condition clone ‘Chhachpur’ recorded maximum height (159.00±24.54 cm) and leaf area (104.25±26.40 cm2) growth, whereas, basal diameter of 12.48±0.55 mm was found maximum in P. deltoides clone ‘90-2’. Standing fresh leaf biomass significantly decreased with advancement in month. Dry leaf biomass increased significantly from September to October. While, significant variation between sites having maximum fresh as well as dry leaf biomass was observed in sub-tropical nursery. It was observed that average height, diameter, leaf area and leaf biomass were almost double in the clones at Sub-tropical (Naganji) nursery as compared to Sub-temperate (Shilli).

Resumen

It is known that the size of monotone arithmetic (+, ·) circuits can be exponentially decreased by allowing just one division “at the very end,” at the output gate. A natural question is: can the size of (+, ·) circuits be substantially reduced if we allow divisions “at the very beginning,” that is, if besides nonnegative real constants and variables x1, …, xn, the circuits can also use their reciprocals 1/x1, ..., 1/xn as inputs. We answer this question in the negative: the gain in circuit size is then always at most quadratic. Over tropical (min, +) and (max, +) semirings, division turns into subtraction; so, reciprocal inputs are then -x1, …, -xn. We give the same negative answer also for tropical circuits. The question of whether reciprocal inputs can substantially speed up tropical (min, +, max) circuits, remains open.

Resumen

Abstract. Dissolved iron (DFe) distributions (<0.2 μm) were determined in the upper water column (0–400 m) of the south eastern tropical and subtropical Pacific, in October–November 2004. Data were collected along a transect extending from the Marquesas Islands to the Chilean coast with most of the stations located in the south Pacific gyre. The concentrations of DFe presented large variability with highest values observed at both extremities of the transect. In the Chilean upwelling, DFe concentrations ranged between 1.2–3.9 nM. These high values result from inputs from the continental margin and are likely maintained by anoxic conditions in the water corresponding to the Oxygen Minimum Zone (OMZ). In subsurface waters near the Marquesas, that were also associated with the extension of the OMZ, DFe concentrations varied between 0.15–0.41 nM. Vertical transport of this water by mesoscale activity eastward of the archipelago may explain the dissymmetric east-west distribution of chlorophyll-a evidenced by satellite images. Using the new tracer Fe*=DFe−rFe:P (PO43−) we show that DFe was in deficit compared to PO43− resulting from the remineralisation of organic matter. This suggests that the Marquesas islands and the surrounding plateau are not a significant source of DFe. In the gyre, DFe concentrations in the upper 350 m water column were around 0.1 nM and the ferricline was located well below the nitracline. These low concentrations reflect the low input of DFe from the atmosphere, from the ventilation of the upper thermocline with water containing low DFe, and from the low biological activity within this ultra oligotrophic gyre.

Resumen

Abstract Bos indicus and Bos taurus cattle diverged from an evolutionary standpoint more than 110,000 years ago. Since then, Bos indicus cattle have undergone genetic adaptations beyond the commonly discussed increased thermo-tolerance and parasite resistance. Several physiological differences exist between Bos indicus and Bos taurus cattle, and it is important to consider these differences when establishing reproductive management strategies. It has been well described that Bos indicus cattle have a delayed onset of puberty and longer periods of postpartum anestrus, yet through the utilization of estrus synchronization protocols these challenges can be attenuated. However, when Bos indicus females are exposed to these protocols, they are known to have smaller dominant follicles, lower expression of estrus, and decreased pregnancy rates to artificial insemination (AI) when compared to Bos taurus females. These factors can be overcome through the utilization of estradiol and progesterone based synchronization protocols, which improve follicular dynamics and yield acceptable pregnancy rates to assisted reproductive technologies in cattle adapted to tropical or subtropical conditions. However, the use of estrogens for synchronization purposes is not permitted in the United States, and cattle producers need to rely on GnRH-based protocols. Another key difference between subspecies, is that Bos indicus females have greater antral follicle counts than Bos taurus females, which proves beneficial for in vitro embryo production. Therefore, an opportunity exists to explore the greater productivity of donors in embryo production in order to improve genetics in herds that utilize these breeds.

Resumen

Abstract. Vertical (cross-isentropic) mixing is produced by small-scale turbulent processes which are still poorly understood and parametrized in numerical models. In this work we provide estimates of local equivalent diffusion in the lower stratosphere by comparing balloon borne high-resolution measurements of chemical tracers with reconstructed mixing ratio from large ensembles of random Lagrangian backward trajectories using European Center for Medium-range Weather Forecasts analysed winds and a chemistry-transport model (REPROBUS). We have investigated cases in subtropical latitudes using data from HIBISCUS campaign. Upper bound on the vertical diffusivity is found to be of the order of 0.5 m2 s−1 in the subtropical region, which is larger than the estimates at higher latitudes. The relation between diffusion and dispersion is studied by estimating Lyapunov exponents and studying their variation according to the presence of active dynamical structures.

Resumen

Pulses have emerged as important rotation crops in Australia. Some are in demand in agricultural production systems due to their high potential market value, because of their roles as grain or forage crops, their nitrogen fixation capability, and because they provide a disease break or improve soil health. While several pulse crops have been identified for winter-season cropping, there are few adapted legumes apart from mungbean that are appropriate for dryland summer cropping. Currently, short-duration crops of mungbean are commonly used, but yields are highly variable and susceptible to drought. Here, we propose that cowpea has the potential to become an alternative rotation crop in dryland summer cropping zones, providing a competitive and profitable alternative pulse crop option where its drought tolerance could enable better performance under inconsistent in-crop rainfall. We demonstrate that cowpea has nutritional properties and putative uses that could prove valuable in emerging plant-based protein and aquaculture markets.

Resumen

In tropical and sub-tropical regions, biomass carbon (C) losses through forest degradation are recognized as central to global terrestrial carbon cycles. Accurate estimation of forest biomass C is needed to provide information on C fluxes and balances in such systems. The objective of this study was to develop generalized biomass models using harvest data covering tropical semi-evergreen, tropical wet evergreen, sub-tropical broad leaved, and sub-tropical pine forest in North East India (NEI). Among the four biomass estimation models (BEMs) tested AGBest = 0.32(D2Hδ)0.75 × 1.34 and AGBest = 0.18D2.16 × 1.32 were found to be the first and second best models for the different forest types in NEI. The study also revealed that four commonly used generic models developed by Chambers (2001), Brown (1989), Chave (2005) and Chave (2014) overestimated biomass stocks by 300–591 kg tree−1, while our highest rated model overestimated biomass by 197 kg tree−1. We believe the BEMs we developed will be useful for practitioners involved in remote sensing, biomass estimation and in projects on climate change mitigation, and payment for ecosystem services. We recommend future studies to address country scale estimation of forest biomass covering different forest types.

Resumen

The sub-tropical ridge at 500 hPa in April has a considerable synoptic scale fluctuation. In April 1988, it showed a steady southward displacement to the equator. In May 1988, a fresh sub-tropical anticyclone formed in northern latitudes by the anticyclonic recut-mg of the dry northwesterlies of extra-tro-pical origin. By extending southward the northerlies ushered a dry spell extensively to the south of the sub-tropical ridge (STR). This was an event contrary to the normal northward progress of equatorial weather belt and the STR. Thus the mean April 500 hPa ridge does not provide a logical parameter for long range forecast-ing of the southwest (SW) monsoon rainfall over India.
