The benefits of publishing systematic quantitative literature reviews for PhD candidates and other early-career researchers

Universities increasingly expect students to publish during a PhD candidature because it benefits the candidate, supervisor, institution, and wider community. Here, we describe a method successfully used by early-career researchers including PhD candidates to undertake and publish literature reviews – a challenge for researchers new to a field. Our method allows researchers new to a field to systematically analyse existing academic literature to produce a structured quantitative summary of the field. This method is a more straightforward and systematic approach than the traditional ‘narrative method’ common to many student theses. When published, this type of review can also complement existing narrative reviews produced by experts in a field by quantitatively assessing the literature, including identifying research gaps. The method can also be used as the initial step for further analysis, including identifying suitable datasets for meta-analysis. Students report that the method is enabling and rewarding.

A review of the impacts of nature based recreation on birds.

Nature based recreation such as wildlife viewing, hiking, running, cycling, canoeing, horse riding and dog walking can have negative environmental effects. A review of the recreation ecology literature published in English language academic journals identified 69 papers from 1978 to 2010 that examined the effect of these activities on birds. Sixty-one of the papers (88%) found negative impacts, including changes in bird physiology (all 11 papers), immediate behaviour (37 out of 41 papers), as well as changes in abundance (28 out of 33 papers) and reproductive success (28 out of 33 papers). Previous studies are concentrated in a few countries (United States, England, Argentina and New Zealand), mostly in cool temperate or temperate climatic zones, often in shoreline or wetland habitats, and mostly on insectivore, carnivore and crustaceovore/molluscivore foraging guilds. There is limited research in some regions with both high bird diversity and nature based recreation such as mainland Australia, Central America, Asia, and Africa, and for popular activities such as mountain bike riding and horse riding. It is clear, however, that non-motorised nature based recreation has negative impacts on a diversity of birds from a range of habitats in different climatic zones and regions of the world.

Comparing hiking, mountain biking and horse riding impacts on vegetation and soils in Australia and the United States of America

Hiking, horse riding and mountain biking are popular in protected areas in Australia and the United States of America. To help inform the often contentious deliberations about use of protected areas for these three types of activities, we review recreation ecology research in both countries. Many impacts on vegetation, soils and trails are similar for the three activities, although there can be differences in severity. Impacts include damage to existing trails, soil erosion, compaction and nutrification, changes in hydrology, trail widening, exposure of roots, rocks and bedrock. There can be damage to plants including reduction in vegetation height and biomass, changes in species composition, creation of informal trails and the spread of weeds and plant pathogens. Due to differences in evolutionary history, impacts on soil and vegetation can be greater in Australia than in the USA. There are specific social and biophysical impacts of horses such as those associated with manure and urine, grazing and the construction and use of tethering yards and fences. Mountain bike specific impacts include soil and vegetation damage from skidding and the construction of unauthorised trails, jumps, bridges and other trail technical features. There are gaps in the current research that should be filled by additional research: (1) on horse and mountain bike impacts to complement those on hiking. The methods used need to reflect patterns of actual usage and be suitable for robust statistical analysis; (2) that directly compares types and severity of impacts among activities; and (3) on the potential for each activity to contribute to the spread of weeds and plant pathogens. Additional research will assist managers and users of protected areas in understanding the relative impacts of these activities, and better ways to manage them. It may not quell the debates among users, managers and conservationists, but it will help put it on a more scientific footing.

Do tourists disperse weed seed? A global review of unintentional human-mediated terrestrial seed dispersal on clothing, vehicles and horses

Human-mediated seed dispersal is recognised as an important, but under-researched, issue. To assess the potential for tourists to act as unintentional seed dispersal agents, we reviewed published and unpublished data on seed dispersal via clothing, vehicles (cars) and in/on horses and donkeys, all of which can be used by tourists. Seeds from 754 species of terrestrial plants have been collected from these vectors, 15% of which are internationally recognised environmental weeds. Seeds were collected from personal clothing and equipment (228 species), the fur of donkeys and horses (42 species), horse dung (216 species) and vehicles (505 species). Most were herbs (429 species) or graminoids (237 species) and native to Europe. Annual Poa, White Clover, Kentucky Bluegrass and Yorkshire Fog were the most frequent species. There have been eight studies specifically on tourists, which identified 12 species on clothing, 26 on vehicles and 133 from horse dung. Methods that minimise the risk of tourists as human-mediated dispersal agents may therefore be appropriate for some tourism activities/destinations: suggestions are made. Further sampling using standardised experimental techniques is required to assess the relative risk associated with specific tourist activities and locations and determine which, and how much, seed is transported.

Alien Plants in the Australian Alps

Abstract The current status of alien plants in the alpine and subalpine areas of the Australian Alps is assessed in this article. The number of alien species has increased following the regions use by nonindigenous Australians over the last 170 years. One hundred and seventy-five alien plant taxa have been recorded above 1500 m in the Australian Alps. These taxa are mainly perennials from Europe, Asia, and the Americas. They are predominantly associated with disturbance and are categorized here according to the types of human activities with which they are associated. There are roadside or path weeds (78% of species), resort weeds (58%), grazing weeds (25%), and rehabilitation weeds (11%). Just over 20% of the alien taxa have become naturalized in the region. Diversity, distribution, and biology of the species are evaluated along with the threats they pose to the conservation of the region.

Recent advances in recreation ecology and the implications of different relationships between recreation use and ecological impacts.

Recreation ecology – the study of the environmental consequences of outdoor recreation/nature-based tourism activities and their effective management – is an emerging field of global importance. A primary research generalization in this field, the use–impact relationship, is commonly described as curvilinear, with proportionally more impact from initial recreation/tourism use. This finding has formed the basis of visitor management strategies in parks, wilderness, and protected areas in many parts of the world. In this paper, however, we argue that the current generalization may be an oversimplification derived from one ecological response: the response of vegetation cover in some plant communities to trampling. Use–response functions for other plant communities, wildlife, soils, and aquatic/marine systems, for example, can differ and require alternative management strategies for sustainable use. On the basis of the available literature, we propose several alternative response relationships.

From barriers to limits to climate change adaptation: path dependency and the speed of change

Research on the barriers and limits to climate change adaptation identifies many factors, but describes few processes whereby adaptation is constrained or may indeed fail to avoid catastrophic losses. It often assumes that barriers are by and large distinct from limits to adaptation. We respond to recent calls for comparative studies that are able to further knowledge about the underlying drivers of barriers and limits to adaptation. We compare six cases from across Australia, including those in alpine areas, rivers, reefs, wetlands, small inland communities, and islands, with the aim of identifying common underlying drivers of barriers and limits to adaptation. We find that the path-dependent nature of the institutions that govern natural resources and public goods is a deep driver of barriers and limits to adaptation. Path-dependent institutions are resistant to change. When this resistance causes the changes necessary for adaptation to be slower than changes in climate, then it becomes a limit to adaptation.

Changes in demand for tourism with climate change: a case study of visitation patterns to six ski resorts in Australia

Tourism in ski resorts depends on snow cover which is expected to decline with climate change. This paper explores hypotheses about demand side responses to climatic change by analyzing patterns of visitation in recent years with differing snow cover. Snow cover and visitation patterns to six resorts which differ in altitude and size in Victoria, Australia, were compared between a slightly warm and much drier year (2006, +0.6°C and −50% precipitation to longer-term averages) to a more typical year (2007) and to nine earlier years. Snowmaking partly offset declines in natural snow cover in 2006, although there were still fewer days with snow on the ground. The number of visitor days was much lower in 2006 than the previous nine years for the three lowest-altitude resorts (−69%), while it actually increased (+10%) in the highest altitude resort where there were fewer visitors (−17%), but they stayed longer. Snowmaking is already critical for ski resorts in low snow years. With warmer conditions, lower-altitude resorts may not receive enough income due to reduced visitation to offset snowmaking costs, while higher-altitude resorts may have a short-term gain, but become uneconomical in the longer term.

Perceptions of climate change impacts, adaptation and limits to adaption in the Australian Alps: the ski-tourism industry and key stakeholders

This paper explores perceptions of ski-tourism representatives and other regional stakeholders about climate change impacts, limits to tourism development and adaptation strategies in the Australian Alps. This area faces rising temperatures, declining rain and snow falls, and shorter skiing seasons. Open-ended interviews examined the perceptions, plans and attitudes of the ski industry and those of conservation managers, local government officials and Australian researchers into tourism and/or climate change effects in the Australian Alps. All interviewees accepted climate change was a reality; several, however, questioned the worst-case scenarios. The major tourism-related adaptation strategies were snowmaking and diversifying to year-round tourism; the success of these strategies will vary according to individual resorts’ snowmaking capacity and potential summer tourism revenue. Currently non-snow-based tourism revenue is worth only approximately 30% of winter revenue. Social resistance to increased water and electricity use for snowmaking emerged as an important issue. Competition for water, including the needs of ecosystems, agriculture and fire protection in this summer-fire-prone region, and fire management issues, is a key concern. Current conflicts between the ski industry and other stakeholders over climate change adaptation call for a collaborative adaptation and change policy within the Australian Alps.
