Abstract: Observational evidence of precipitation extremes is vital to better understand how these events might change in a future warmer climate. Over the terrestrial regions of a quasi-global domain, we assess the representation of annual maxima of daily precipitation (Rx1day) in 22 observational products gridded at 1° × 1° resolution and clustered into four categories: station-based in situ , satellite observations with or without a correction to rain gauges, and reanalyses (5, 8, 4 and 5 datasets, respectively). We also evaluate the interproduct spread across the ensemble and within the four clusters, as a measure of observational uncertainty. We find that reanalyses present a heterogeneous representation of Rx1day in particular over the tropics, and their interproduct spread is the highest compared to any other cluster. Extreme precipitation in satellite data broadly compares well with in situ -based data. We find a general better agreement with in situ -based observations and less interproduct spread for the satellite products with a correction to rain gauges compared to the uncorrected products. Given the level of uncertainties associated with the estimation of Rx1day in the observations, none of the datasets can be thought of as the best estimate. Our recommendation is to avoid using reanalyses as observational evidence and to consider in situ and satellite data (the corrected version preferably) in an ensemble of products for a better estimation of precipitation extremes and their observational uncertainties. Based on this we choose a subs le of 10 datasets to reduce the interproduct spread in both the representation of Rx1day and its timing throughout the year, compared to all 22 datasets. We emphasize that the recommendations and selection of datasets given here may not be relevant for different precipitation indices, and other grid resolutions and time scales.

Abstract: Wildlife populations are vanishing at alarmingly high rates. This issue is being addressed by organisations around the world and when utilizing social media sites like Instagram, images are potentially more powerful than words at conveying crucial conservation messages and garnering public support. However, different elements of these images have been shown to potentially have either positive or negative effects on viewers’ attitudes and behaviours towards wildlife and towards the organisation posting the image. This study used a quantitative content analysis to assess the most common and engaging elements of wildlife images posted to Instagram in 2020 and 2021, using Australian conservation organisations as a case study. A total of 670 wildlife images from the Instagram accounts of 160 conservation organisation Instagram accounts were coded and analysed. Results highlight that the most common image elements used included natural backgrounds, mammals and birds, and no human presence. In addition, it was found that the taxon of the animal featured in a post and the presence of humans did not impact engagement levels. Our findings highlight the potential for Instagram posts to feature and promote a wide range of currently underrepresented species, and for conservation organisations to be able to confidently share and post images that promote positive perceptions of both the animal and the conservation organisation.

Abstract: Abstract. We introduce the Frequent Rainfall Observations on GridS (FROGS) database (Roca et al., 2019). It is composed of gridded daily-precipitation products on a common 1∘×1∘ grid to ease intercomparison and assessment exercises. The database includes satellite, ground-based and reanalysis products. As most of the satellite products rely on rain gauges for calibration, unadjusted versions of satellite products are also provided where available. Each product is provided over its length of record and up to 2017 if available. Quasi-global, quasi-global land-only, ocean-only and tropical-only as well as regional products (over continental Africa and South America) are included. All products are provided on a common netCDF format that is compliant with Climate and Forecast (CF) Convention and Attribute Convention for Dataset Discovery (ACDD) standards. Preliminary investigations of this large ensemble indicate that while many features appear robust across the products, the characterization of precipitation extremes exhibits a large spread calling for careful selection of the products used for scientific applications. All datasets are freely available via an FTP server and identified thanks to the DOI: 0.14768/06337394-73A9-407C-9997-0E380DAC5598.

Abstract: With the rising popularity of social media, conservation organisations and zoos need to understand its impact on public perceptions of the animals they house and their role in conservation. In addition, many zoos offer close-encounter experiences, and visitors frequently share images from these experiences online. This study measured the effects that viewing such encounter images had on public perceptions of both the zoo and the animals they saw. One of sixteen images was randomly presented to participants in two s les: one of Zoo Community followers and members of Zoos Victoria (n = 963), and a representative s le of the Australian public (n = 1619). Each image featured one of four animals (Eclectus parrot, Kangaroo Island kangaroo, Monteith’s leaf insect, Centralian carpet python) and one of four human positions (human and animal touching, human and animal ~30 cm apart, human and animal ~1 m apart, animal alone). Results indicated that viewing different animals and the different human positions within these human–animal encounter images can affect public perceptions of zoo animals. In particular, the closer the proximity of a human to an animal in an image, the more likely respondents were to think that the animal was not displaying a natural behaviour and the more likely it was for General Public respondents to think that the animal would make a good pet. These findings can be used by zoos, wildlife tourism, and media organisations to ensure that they are sending clear, positive, and intended messages about zoo facilities and animals, as well as providing insights into animal encounter images in wider settings.

Abstract: An often overlooked impact of urbanisation is a reduction in our ability to connect with nature in our daily lives. If people lose the ability to connect with nature we run the risk of creating a nature-disconnect, which is hypothesised to have an impact on our empathy for other species and our desire to help conservation efforts. Understanding how a sense of connection with nature can impact upon people's decisions to seek out nature in their daily lives is important if we wish to encourage the practice of wildlife gardening as a tool to enhance both urban bio ersity and connectedness to nature. This study targeted members of wildlife gardening programmes (n=261) and members of the general public (n=417) and provides empirical evidence that connectedness to nature is a primitive belief, but also shows that a strong sense of connection with nature is not a prerequisite for engaging in wildlife gardening.

Abstract: Adaptation to climate change is imperative for the resilience of smallholder agriculture in many developing countries. While studies have focused on climatic impacts on crops and adaptation decisions, barriers to the uptake of adaptation measures by smallholder farmers remain largely unexplored. We empirically quantified the adoption of adaptation measures, as well as barriers to adoption and their determinants for smallholder agriculture in Far Western Province, Nepal, based on a survey of 327 smallholder farmers. We established relationships between barriers and adoption for three different agroecosystems: the Mountain, Hill, and Terai. We then used multiple regression to identify the determinants of barriers in the broader study area, as well as across agroecosystems. We found that adaptation measures such as crop adjustment, farm management, and fertiliser management were practised across all regions. Techno-informational, economic, and environmental barriers were strongly and inversely correlated with adoption of adaptation measures. Adoption, barriers, and determinants varied across agroecosystems. The findings indicate that agricultural development policies must consider climate change adaptation measures tailored to specific agroecosystems in order to most effectively alleviate barriers and promote smallholder resilience.

Abstract: In Australia, the management of feral horse populations is a contentious issue, owing to their pluralistic status as an introduced pest and a national icon. In this review, we synthesise current knowledge of the ecological effects of feral horses and the human dimensions of feral horse management, using case studies from around the world to illustrate contentious and successful management practices. We highlight gaps in the literature and suggest that more peer-reviewed research would be beneficial in reducing the current public controversy surrounding management of feral horses.

Abstract: It is now widely accepted that it is important to understand the ‘human dimensions’ of wildlife management issues in order to achieve management goals. This growing field of study was born in the 1960s and involves an examination of societal values, knowledge and behaviours associated with wildlife and wildlife management issues. This paper provides an overview of the history and directions in human dimensions research, focusing specifically on its application for wildlife population management in Australasia (in particular, Australia and New Zealand). It also provides a ‘toolkit’ of methods and approaches for those wishing to undertake, interpret or utilise human dimensions enquiries.

Abstract: The achievement of global sustainability agendas, such as the Sustainable Development Goals, relies on transformational change across society, economy, and environment that are co‐created in a transdisciplinary exercise by all stakeholders. Within this context, environmental and societal change is increasingly understood and represented via participatory modeling for genuine engagement with multiple collaborators in the modeling process. Despite the ersity of participatory modeling methods to promote engagement and co‐creation, it remains uncertain what the extent and modes of participation are in different contexts, and how to select the suitable methods to use in a given situation. Based on a review of available methods and specification of potential contextual requirements, we propose a unifying framework to guide how collaborators of different backgrounds can work together and evaluate the suitability of participatory modeling methods for co‐creating sustainability pathways. The evaluation of method suitability promises the integration of concepts and approaches necessary to address the complexities of problems at hand while ensuring robust methodologies based on well‐tested evidence and negotiated among participants. Using two illustrative case studies, we demonstrate how to explore and evaluate the choice of methods for participatory modeling in varying contexts. The insights gained can inform creative participatory approaches to pathway development through tailored combinations of methods that best serve the specific sustainability context of particular case studies.

Abstract: The aim of this study was to examine the values and attitudes held by Australasian wildlife managers as they relate to wildlife management issues, and to gain some insight into possible future directions and priorities for Australasian wildlife management. During December 2002 – February 2003, 138 questionnaires were completed by members of the Australasian Wildlife Management Society (AWMS) and registrants of the 2002 AWMS annual conference. Threatened species management, threatened communities/habitats, and management of introduced species were the issues rated as needing the highest priority for the Australasian Wildlife Management Society. Issues such as animal rights, genetically modified organisms and timber harvesting on public lands were the lowest-rating issues. Respondents expressed a strong belief in managing and controlling wildlife to achieve wildlife management objectives, a strong belief that wildlife should be protected and that wildlife managers should minimise the pain and suffering of in idual animals, and a belief that resources should be directed towards conserving wildlife populations rather than protecting in idual animals from non-threatened populations. While respondents held a strong belief that it is important to consult the community when developing wildlife management policies and programs, there was little support for a comanagerial approach where the community has a significant role to play in decision-making processes.

Abstract: A range of in situ , satellite and reanalysis products on a common daily 1° × 1° latitude/longitude grid were extracted from the Frequent Rainfall Observations on Grids database to help facilitate intercomparison and analysis of precipitation extremes on a global scale. 22 products met the criteria for this analysis, namely that daily data were available over global land areas from 50°S to 50°N since at least 2001. From these daily gridded data, 10 annual indices that represent aspects of extreme precipitation frequency, duration and intensity were calculated. Results were analysed for in idual products and also for four cluster types: (i) in situ , (ii) corrected satellite, (iii) uncorrected satellite and (iv) reanalyses. Climatologies based on a common 13-year period (2001–2013) showed substantial differences between some products. Timeseries (which ranged from 13 years to 67 years) also highlighted some substantial differences between products. A coefficient of variation showed that the in situ products were most similar to each other while reanalysis products had the largest variations. Reanalyses however agreed better with in situ observations over extra-tropical land areas compared to the satellite clusters, although reanalysis products tended to fall into ‘wet’ and ‘dry’ c s overall. Some indices were more robust than others across products with daily precipitation intensity showing the least variation between products and days above 20 mm showing the largest variation. In general, the results of this study show that global space-based precipitation products show the potential for climate scale analyses of extremes. While we recommend caution for all products dependent on their intended application, this particularly applies to reanalyses which show the most ergence across results.

Abstract: We present the second update to a data set of gridded land‐based temperature and precipitation extremes indices: HadEX3. This consists of 17 temperature and 12 precipitation indices derived from daily, in situ observations and recommended by the World Meteorological Organization (WMO) Expert Team on Climate Change Detection and Indices (ETCCDI). These indices have been calculated at around 7,000 locations for temperature and 17,000 for precipitation. The annual (and monthly) indices have been interpolated on a 1.875°×1.25° longitude‐latitude grid, covering 1901–2018. We show changes in these indices by examining ”global”‐average time series in comparison with previous observational data sets and also estimating the uncertainty resulting from the nonuniform distribution of meteorological stations. Both the short and long time scale behavior of HadEX3 agrees well with existing products. Changes in the temperature indices are widespread and consistent with global‐scale warming. The extremes related to daily minimum temperatures are changing faster than the maximum. Spatial changes in the linear trends of precipitation indices over 1950–2018 are less spatially coherent than those for temperature indices. Globally, there are more heavy precipitation events that are also more intense and contribute a greater fraction to the total. Some of the indices use a reference period for calculating exceedance thresholds. We present a comparison between using 1961–1990 and 1981–2010. The differences between the time series of the temperature indices observed over longer time scales are shown to be the result of the interaction of the reference period with a warming climate. The gridded netCDF files and, where possible, underlying station indices are available from www.metoffice.gov.uk/hadobs/hadex3 and www.climdex.org .

Abstract: It is now well established that men and women often differ significantly in their attitudes and responses to workplace situations, challenges and policies. The aim of this study was to examine the effect of gender on perceptions and priorities held by Australasian wildlife managers. Data were collected via a questionnaire distributed during December 2002 – February 2003 to members of the Australasian Wildlife Management Society (AWMS) and registrants of the 2002 AWMS annual conference. The results show that there are now significantly more female AWMS members than there were in the early 1990s, a possible indication of a change in the wider wildlife management profession in Australasia. Consistent with previous research, male respondents held different views from female respondents about wildlife and wildlife management. In particular, male respondents were significantly more likely to express the ‘management/consumptive use of wildlife’ perspective than female respondents. Interestingly, this gap was observed only in the 18–30-year age category. The paper examines what these differences might mean for the future of wildlife management in Australasia.

Abstract: This paper explores the management implications of a recent study that was designed to explore public and stakeholder values of wildlife in Victoria, Australia. Questionnaires (n = 1431) were used to examine values and knowledge of wildlife held by residents from seven Victorian municipalities and members of six wildlife management stakeholder groups. The results suggest that most Victorians have a relatively strong emotional attachment to in idual animals (the humanistic value) and are interested in learning about wildlife and the natural environment (the curiosity/learning/interacting value). In comparison, the negativistic, aesthetic, utilitarian-habitat and dominionistic/wildlife-consumption values were not expressed as strongly. These findings suggest that wildlife managers should expect support for wildlife management objectives that reflect the relatively strong humanistic orientation of Victorians and tailor management and education programs to appeal to this value and Victorians' interest in learning about wildlife.

Abstract: Feeding wild birds is a common and popular human-wildlife interaction throughout the world. However, controversy exists over the benefits and costs to the birds and humans involved. This bibliometric study documents wild bird feeding policies around the globe and examines environmental and socio-cultural factors which may influence the position adopted by these policies. We located 412 policies from 237 different countries, territories or dependencies (jurisdictions) 58.7% of jurisdictions had no information available online regarding wild bird feeding policy. Generalized Linear Modelling revealed that colder minimum ambient temperatures were associated with more pro-feeding policy settings. An index of controversy was calculated for each jurisdiction most (77.6%) had no controversy. This study highlights the significant variation in policy settings for wild bird feeding across jurisdictions and controversy in almost a quarter of jurisdictions. Recommendations are made for the development of clear, consistent and readily available policy advice on this globally popular human-wildlife interaction.
