Abstract	Managed grasslands can be net sources or sinks for three major greenhouse gases (CO2, CH4 and N2O). We measured the exchange of these gases for three years over an irrigated, intensively-managed dairy pasture in New Zealand that was grazed ten times per year. We also measured the greenhouse gas (GHG) exchanges over a neighbouring dryland pasture for two years, including its conversion to a winter-forage kale crop in the second year and the grazing of that crop. From the gas exchanges, measurements of the grazed biomass, and estimates of other imports and exports we obtained annual net carbon (C) budgets and GHG budgets for these ecosystems. The irrigated pasture system (excluding cows) removed CO2 from the atmosphere, 423 (±23)gC m−2yr−1 on average, and when considering the other C inputs and outputs it was also a net C sink in each year, gaining 81 (±27)gCm−2yr−1 on average. The net CO2 uptake of the dryland in the conversion year was about half that of the irrigated pasture, and its net C budget was neutral. The irrigated pasture, without grazing cows, emitted CH4 throughout all seasons. These emissions were about 15 times greater than emissions expected just from cow dung; we cannot discern what fractions originated from the soil and the pasture plants, respectively. At the dryland/kale site, CH4 emissions of the same magnitude occurred. The emissions of N2O from the irrigated pasture were 0.68 (±0.026)gNm−2yr−1 on average (± standard error), and about half that from the kale crop. These results agree reasonably well with expected emissions based on the N inputs from fertiliser and excreta, using emission factors from New Zealand’s national GHG inventory; however, it is unclear what fraction of the observed emissions can be considered as non-anthropogenic background fluxes. For the irrigated pasture, the global-warming potential of the N2O emissions (expressed as CO2-equivalent mass) was approximately equal to the net C uptake. Hence, the pasture was offsetting its own N2O emissions. However, CH4 emissions directly from cows (calculated from the cows’ feed intake) were two to three times greater than the N2O emissions, and about six times greater than the pasture’s CH4 emissions. Therefore, the dairy system including pasture and cows was a net GHG source.

Abstract	Toxoplasma gondii is a common parasite that infects warm-blooded animals and influences host physiology. T. gondii is known to target the host's central nervous system, affecting circulating levels of steroid hormones, fear-related behaviors, and health, although these effects appear to vary among host taxa. Here, we investigated the relationship between T. gondii infection and levels of plasma testosterone and cortisol within a wild population of spotted hyenas (Crocutacrocuta, n = 109). In our analyses, we accounted for age and sex via stratified regression analyses. We detected a negative association between circulating plasma testosterone and T. gondii infection among female cubs and subadults as well as adult male hyenas. We found no associations between T. gondii infection and cortisol in any age class or sex group of hyenas. Our work adds to a growing body of literature by characterizing the relationship between T. gondii infection and physiology in a novel host in its natural habitat. In a broader context, our findings indicate that responses to infection vary with characteristics of the host and point to a clear need for additional studies and priorities for future work that include diverse taxa and ecological settings.

Article ; Online: Model for calculating ammonia emission from stored animal liquid manure

Abstract	Ammonia (NH₃) emissions from agriculture have increased by 90% from 1970 to 2005, and agriculture is now the largest source of NH₃ to the atmosphere. Calculated national NH₃ emissions from agriculture using static emission factors do not reflect regional conditions. We propose, parameterize and test a simple model to calculate emission rates which incorporates effects of temperature, pH, total ammoniacal nitrogen (TAN) concentration, exposed storage area, and storage cover. This is the first time that several known algorithms were combined in this semi-dynamic user-friendly model concept and that model parameters (uploaded on the internet) were estimated from a unique database comprising 44 studies. The calculator is designed to be used correctly even if there exists only little knowledge about manure chemistry or micrometeorology, and can calculate emissions with a low demand for input data Calculations using the new model are as accurate as the standard method. The proposed approach has two advantages compared to the standard alternative: it does not require an estimate of TAN flow through the store, and calculated values reflect management (e.g., storage area or covers), TAN concentration, pH and temperature based on well-established principles. The simple and process-related approach has the potential to deliver more accurate estimates after a more precise parameterization from dedicated studies where the focus is on emission measurements, slurry composition characterization, air and slurry temperature and turbulence. To facilitate this approach, data need to be collected over relatively short time intervals (less than twice per day) to ensure that they cover cardinal diurnal conditions at the same time and right place. A spreadsheet implementation of the model is publicly available from https://github.com/sashahafner/AMOSTO.

Abstract	Previous soil sampling from grazed pastures in New Zealand compared the changes of soil organic carbon (SOC) in adjacent irrigated and unirrigated portions of the same paddocks. It showed that irrigated portions had lower SOC stocks than unirrigated portions, with an average difference of 7.0 tC ha⁻¹ or 0.6 tC ha⁻¹ yr⁻¹. These findings have formed the basis of an assessment for the net effect of conversion of New Zealand's grazed pastures to irrigation. However, since cattle could move freely between irrigated and unirrigated portions of the studied paddocks, there could have been different grazing intensities and/or excreta transfer between the irrigated and unirrigated portions of the same paddocks. Both these factors could have affected SOC stocks. In this study, we used the process-based model, CenW, to simulate the consequences of this possible carbon transfer via animal excreta and different grazing intensities. We found that the observed increase of 0.6 tC ha⁻¹ yr⁻¹ in SOC stock in the unirrigated portions could result from a transfer of 20% excreta from the irrigated to unirrigated portions (with an area ratio of 6:1) of a paddock and with the unirrigated portions being grazed only lightly with 2.0 tDM ha⁻¹ in foliage biomass residuals remaining after grazing. That means that the observed higher SOC stocks in the unirrigated portions could potentially be attributable to the behaviour of grazing animals. We suggest that a realistic extent of carbon transfer and/or differences in grazing intensities could be sufficient to account for the observed differences in SOC stocks even if irrigation per se caused no differences in carbon stocks. It is therefore inappropriate to ascribe the change of SOC to irrigation effects based on experimental findings where SOC changes can be affected by the behaviour of grazing animals.

Abstract	Diversity is a key driver of scientific innovation, yet fields in science, technology, engineering, and mathematics (STEM) have struggled to retain diverse communities. Research suggests that fostering a sense of belonging is critical for retaining diversity. We propose an iterative process that aims to improve sense of belonging among laboratory (lab) members through self-reflection and community collective action.

Abstract	Intensification of agricultural management practices, including irrigation and addition of nitrogen (N) fertilizers, can lead to enhanced N leaching and loss of soil fertility. In New Zealand, expansion of the dairy industry has rapidly increased irrigated land area, particularly on shallow, stony soils of the Canterbury region that are prone to leaching, leading to degradation of surface- and ground-water quality and losses of soil N and carbon (C). In this study, we measure components of N balance for two adjacent fields of lucerne (Medicago sativa L., alfalfa) harvested for cut-and-carry feed and grazed in situ. One field was non-irrigated and one irrigated with both water and dairy effluent. Inputs from N fixation associated with the legume crop were quantified using a natural abundance isotopic approach. Drainage from the root zone and leaching were measured with 6 large lysimeters in each field. Leaching losses from non-irrigated lucerne were 7–30 kg N ha⁻¹ y⁻¹ with the largest losses occurring in a year with primarily grazing management. Losses from irrigated lucerne were 39–102 kg N ha⁻¹ y⁻¹, with the largest losses resulting from summer drainage events exacerbated by irrigation. Fixation of N was the largest input to both systems, contributing 192–257 kg N ha⁻¹ y⁻¹ for non-irrigated lucerne. Under irrigation, biomass production increased, but N uptake from effluent and soil stocks contributed to biomass N to a greater extent and fixation was 262–286 kg N ha⁻¹ y⁻¹. Management influenced N balance through inputs from animal excreta and effluent additions and exports through harvest and grazing removals. Management practices which reduce N losses from the soil are needed to minimize environmental impacts and protect soil fertility.

Abstract	Environmental factors early in life can have lasting influence on the development and phenotypes of animals, but the underlying molecular modifications remain poorly understood. We examined cross‐sectional associations among early life socioecological factors and global DNA methylation in 293 wild spotted hyenas (Crocuta crocuta) in the Masai Mara National Reserve, Kenya, grouped according to three age classes (cub, subadult and adult). Explanatory variables of interest included annual maternal rank based on outcomes of dyadic agonistic interactions, litter size, wild ungulate prey density and anthropogenic disturbance in the year each hyena was born based on counts of illegal livestock in the Reserve. The dependent variable of interest was global DNA methylation, assessed via the LUminometric Methylation Assay, which provides a percentage methylation value calculated at CCGG sites across the genome. Among cubs, we observed approximately 2.75% higher CCGG methylation in offspring born to high‐ than low‐ranking mothers. Among cubs and subadults, higher anthropogenic disturbance corresponded with greater %CCGG methylation. In both cubs and adults, we found an inverse association between prey density measured before a hyena was 3 months old and %CCGG methylation. Our results suggest that maternal rank, anthropogenic disturbance and prey availability early in life are associated with later life global DNA methylation. Future studies are required to understand the extent to which these DNA methylation patterns relate to adult phenotypes and fitness outcomes.
