Examining how companies’ support of tourist attractions affects visiting intentions: The mediating role of perceived authenticity

As public funding for the restoration of tourist attractions decreases, assistance is often sought from the private sector in the form of corporate social responsibility (CSR). However, research has yet to understand how such CSR activities impact the beneficiary, namely tourist attractions. Thus, extending past CSR literature, we explore whether differing company CSR motivations can influence a tourists’ visiting intentions. The results of two experimental studies show low company altruism (e.g., demanding to acquire naming rights of the site), compared to high company altruism (e.g., demanding nothing in return), decreases visiting intentions. Furthermore, we show that perceived authenticity of the site mediates this effect. Finally, we find the negative effect of low altruistic CSR is mitigated in the case of no heritage. Based on the results, we show tourist attraction managers should be wary of companies displaying nonaltruistic intentions, as such activity may have harmful consequences

Tree water use under conditions of drought

The impact of drought on tree water use was investigated in remnant forest in the Liverpool Plains NSW. Tree water use was measured using commercial sap flow testers from December 2002 to September 2004 which corresponded with a period of drought and a period of higher rainfall. Understorey evapotranspiration and soil moisture were also measured. Water use of the stand of trees was a larger proportion of annual total rainfall (87%) during the drought period than during the post-drought period (50% water use) when rainfall was higher. Understorey water use was about 20% of rainfall, suggesting that the understorey evapotranspiration component of the water balance can make a significant contribution to water use and the availability of water for groundwater recharge. The results indicate that the remnant forest was able to survive during the drought because of deep roots. The findings also demonstrate the valuable role forests play in maintaining the hydrological balance and in ameliorating the development of dryland salinity in agricultural areas (A).4 page(s

Daily, seasonal and annual patterns of transpiration from a stand of remnant vegetation dominated by a coniferous Callitris species and a broad-leaved Eucalyptus species

Quantifying water use of native vegetation is an important contribution to understanding landscape ecohydrology. Few studies provide long-term (more than one growing season) estimates of water use and even fewer quantify interseasonal and interannual variation in transpiration. Globally, changes in land use are significantly altering landscape ecohydrology, resulting in problems such as dryland salinity and excessive groundwater recharge. Estimating stand water use is complex in multispecies forests, due to the differences in relationships among sapwood area, basal area and tree size for co-occurring species. In this article, we examine seasonal and interannual variation in transpiration rate of the tree canopy of two co-occurring species (a conifer Callitris glaucophylla J. Thompson & L.A.S. Johnson and a broad-leaved Eucalyptus crebra F. Muell.) in an open woodland in eastern Australia. Evapotranspiration of understorey species was measured using an open-top chamber, and tree water use was measured using heat-pulse sap flow sensors. Annual stand transpiration was 309 mm in 2003, a year of below average rainfall, and 629 mm in 2004, a year with higher-than-average rainfall. Despite an almost doubling (522 vs. 1062 mm) of annual rainfall between 2003 and 2004, annual tree water use remained a constant fraction (59%) of rainfall, indicative of compensatory mechanisms linking annual rainfall, leaf area index and tree water use. Deep drainage was estimated to be 4% of rainfall (20.8 mm) in 2003 and 2% (21.2 mm) in 2004, indicating that this native woodland was able to minimize deep drainage despite large interannual variability in rainfall.10 page(s

Consequences of nocturnal water loss : a synthesis of regulating factors and implications for capacitance, embolism and use in models

Total daily water use is a key factor influencing the growth of many terrestrial plants, and reflects both day-time and nocturnal water fluxes. However, while nocturnal sap flow (En) and stomatal conductance (gs,n) have been reported across a range of species, ecosystems and microclimatic conditions, the regulation of these fluxes remains poorly understood. Here, we present a framework describing the role of abiotic and biotic factors in regulating Enand gs,nhighlighting recent developments in this field. Across ecosystems, Enand gs,ngenerally increased with increasing soil water content and vapor pressure deficit, but the interactive effects of these factors and the potential roles of wind speed and other abiotic factors remain unclear. On average, gs,n and En are higher in broad-leaved compared with needle-leaved plants, in C3compared with C4 plants, and in tropical compared with temperate species. We discuss the impacts of leaf age, elevated [CO₂] and refilling of capacitance on night-time water loss, and how nocturnal gs,nmay be included in vegetation models. Younger leaves may have higher gs,n than older leaves. Embolism refilling and recharge of capacitance may affect sap flow such that total plant water loss at night may be less than estimated solely from En measurements. Our estimates of gs,n for typical plant functional types, based on the published literature, suggest that nocturnal water loss may be a significant fraction (10-25%) of total daily water loss. Counter-intuitively, elevated [CO₂] may increase nocturnal water loss. Assumptions in process-based ecophysiological models and dynamic global vegetation models that gs is zero when solar radiation is zero are likely to be incorrect. Consequently, failure to adequately consider nocturnal water loss may lead to substantial under-estimation of total plant water use and inaccurate estimation of ecosystem level water balance.9 page(s

Seasonal variations in tree water use and physiology correlate with soil salinity and soil water content in remnant woodlands on saline soils

Ecophysiological studies of remnant woodlands in saline environments are scarce. We investigated seasonal fluctuations in soil water and salinity together with leaf and branch traits (area-based maximum assimilation (Amax), foliar nitrogen, specific leaf area (SLA) and Huber value (Hv)) and sap velocities of Eucalyptus macrorhyncha at four semi-arid sites in south-eastern Australia. Summer and winter soil salinities (10 cm depth) were 15-35 dS m⁻¹ and 8-10 dS m⁻¹ respectively. Gravimetric soil water content in the upper 20 cm was 2-5% in summer and 7-23% in winter, resulting in a significant inverse correlation between soil water and soil salinity. We found significant correlations between soil conditions and plant traits and function across seasons. Soil water content was significantly correlated with foliar N, SLA, Hv and maximum sap velocity while soil salinity was significantly correlated with Amax, Hv and maximum sap velocity. Correlations indicate co-variation of soil conditions and plant physiology in response to environmental conditions such as solar radiation and vapour pressure deficit (D). E. macrorhyncha tolerates the dual stresses of high salinity and low soil water during summer. While the plants appeared unhealthy, our data show that remnant vegetation can remain functional even in close proximity to saline scalds.9 page(s

Root biomass distribution and soil properties of an open woodland on a duplex soil

Data on the distribution of root biomass are critical to understanding the ecophysiology of vegetation communities. This is particularly true when models are applied to describe ecohydrology and vegetation function. However, there is a paucity of such information across continental Australia. We quantified vertical and horizontal root biomass distribution in a woodland dominated by 'Angophora bakeri' and 'Eucalyptus sclerophylla' on the Cumberland Plains near Richmond, New South Wales. The site was characterised by a duplex (texture contrast) soil with the A horizon (to 70 cm) consisting of loamy sand and the B horizon (to > 10 m) consisting of sandy clay. The topsoil had a smaller bulk density, a smaller water holding capacity but a larger organic component and a larger hydraulic conductivity in comparison to the subsoil. Root biomass was sampled to 1.5 m depth and declined through the soil profile. Whilst total biomass in the B horizon was relatively small, its contribution to the function of the trees was highly significant. Coarse roots accounted for approximately 82% of the root mass recovered. Lateral distribution of fine roots was generally even but coarse roots were more likely to occur closer to tree stems. Variation in tree diameter explained 75% of the variation in total below-ground biomass. The trench method suggested the below-ground biomass was 6.03 ± 1.21 kg m⁻² but this method created bias towards sampling close to tree stems. We found that approximately 68% of root material was within a 2 m radius of tree stems and this made up 54% of the total number of samples but in reality, only approximately 5 to 10% of the site is within a 2 m radius of tree stems. Based on these proportions, our recalculated below-ground biomass was 2.93 ± 0.59 kg mm⁻². These measurements provide valuable data for modeling of ecosystem water use and productivity

Aboriginal interpretation in Australian wildlife tourism

This paper evaluates Aboriginal cultural interpretation at wildlife attractions and on wildlife tours in Australia. The sites included 14 wildlife parks or zoos; three Aboriginal-owned emu or crocodile farms; and 16 wildlife tours, river cruises or resorts with Indigenous interpretation of wildlife. Telephone interviews were conducted with 35 managers (nine Indigenous) and 26 Indigenous staff at wildlife attractions that included verbal or written Aboriginal wildlife interpretation. The Indigenous guides verbally presented both traditional uses and personal stories about Australian wildlife followed by Aboriginal 'Dreaming' or creation stories about totemic animal species. Non-Indigenous staff explained traditional Aboriginal uses of wildlife followed by biological facts and species information. The responses in this study thus highlight cultural differences in animal attitudes and approaches to wildlife use or interpretation. According to staff, tourists benefit from the inclusion of Aboriginal interpretation at wildlife sites by broadening their mind, dispelling myths, learning/education about Aboriginal cultures, novelty and excitement for visitors, increasing cultural awareness and developing more positive attitudes towards Indigenous people. Some guidelines for wildlife attractions and tours to develop and present Aboriginal cultural interpretation of Australian wildlife are also identified

Economic costs of informal care for people with chronic diseases in the community: lost income, extra welfare payments, and reduced taxes in Australia in 2015-2030

We estimated the economic costs of informal care in the community from 2015 to 2030, using an Australian microsimulation model, Care&WorkMOD. The model was based on data from three Surveys of Disability, Ageing, and Carers (SDACs) for the Australian population aged 15-64\ua0years old. Estimated national income lost was AU$3.58 billion in 2015, increasing to$5.33 billion in 2030 (49% increase). Lost tax payments were estimated at AU$0.99 billion in 2015, increasing to AU$1.44 billion in 2030 (45% increase), and additional welfare payments were expected to rise from $1.45 billion in 2015 to AU$1.94 in 2030 (34% increase). There are substantial economic costs both to informal carers and the government due to carers being out of the labour-force to provide informal care for people with chronic diseases. Health and social policies supporting carers to remain in the labour force may allow governments to make substantial savings, while improving the economic situation of carers
