    The far north Queensland microclimate (FNQ-microclim) is an ongoing long-term microclimate monitoring project from across five tropical rainforest sites (Daintree Rainforest SuperSite, Cape Tribulation; Daintree Rainforest SuperSite, Cow Bay; Rex Range; Mt. Lewis National Park; Mt. Bellenden Ker), located within an elevation range of 40 - 1550 m a.s.l. Microclimatic parameters measured include: a) air temperature (about 15 cm above ground), b) near surface temperature at the interface between soil and air (less than 1 cm above ground), c) top soil temperature (about 10 cm below ground), and d) top soil moisture. Data are recorded every 15 minutes using the TMS-4 sensors (Temperature Moisture Sensor, T.M.O.S.T s.r.o, Prague, Czech Republic).

    The acquisition of sunphotometer measurements are critical to capture vital data on atmospheric properties during airborne hyperspectral imaging campaigns as well as for measurements coinciding with the overpass of satellite sensors. The atmospheric properties measured are used in atmospheric correction of the remotely sensed image data. This data is primarily for input into atmospheric correction systems. It may also prove of use in validation of aerosol products such as MOD04 and the reflectance change method developed as part of CRC-SI project 4.1 which may be integrated into the Auscover 19 band reflectance product processing. It can also be used to check methods that produce water vapour directly from the data (SODA). The MicroTops instruments referred to here capture solar radiance data in 5 wavelengths which are used to extract information on aerosol optical thickness and water vapour content. These two key parameters of interest are used as inputs for the atmospheric correction of remotely sensed image data.

    The project is focused on the topic, 'enhanced heat tolerance of virus-infected aphids lead to niche expansion and reduced interspecific competition. The two aphid species studied are <i>Rhopalosiphum padi</i> and <i>Rhopalosiphum maidis</i>. The project had some of the following objectives: [1] Spatial distribution of two aphid species on the host plants [2] Upper thermal limits of two aphid species. [3] Effects of the viral infection on the host plant thermal profile. [4] Levels of expression of heat shock protein genes of virus-free and viruliferous aphids. [5] Locomotor capacity of aphids, effects of viruses on the locomotor capacity. [6] Effects of viral infection, temperature, and competition on the lifespan and fecundity of <i>R. padi</i> [7] Effects of viral infection, temperature, and competition on the lifespan and fecundity of <i>R. maidis</i> [8] Temperature of acrylic tubes used on aphid experiments. [9] Thermal lethal dose 50 of virus-free and viruliferous aphids [10] Thermal preference of virus-free and viruliferous aphids. This information can be very useful for ecologist working on insect population dynamics as well as physiologist and eco-physiologists doing meta-analyses of expression of heat shock protein genes induced by symbionts.

    Heatwaves are defined as unusually high temperature events that occur for at least three consecutive days with major impacts to human health, economy, agriculture and ecosystems. This dataset provides time-series of heatwave characteristics such as peak temperature, number of events, frequency and duration from 1950 to 2016 in Australia. The analysis were based on daily minimum and maximum temperature obtained from the Australian Water Availability Project (AWAP). The data is available as spatial time-series (5km grid-cell) and aggregated time-series for all Local Government Areas in Australia.

    <p>This dataset contains audio files for TERN Whroo Dry Eucalypt SuperSite. Long-term recordings of the environment can be used to identify sound sources of interest, characterise the soundscape, aid in the assessment of fauna biodiversity, monitor temporal trends and track environmental changes.</p> <p>The site was established in 2011 in box woodland dominated by <em>Eucalyptus microcarpa</em> (grey box) and <em>Eucalyptus leucoxylon</em> (yellow gum). Smaller numbers of <em>Eucalyptus sideroxylon</em> (ironbark) and <em>Acacia pycnantha</em> (golden wattle) are also found on site. Elevation of the site is close to 165 m and mean annual precipitation from a nearby Bureau of Meteorology site measure 558 mm. Maximum temperatures range from 29.8°C (in January) to 12.6°C (in July), while minimum temperatures range from 14.2°C (in February) to 3.2°C (in July). Maximum temperatures vary on a seasonal basis by approximately 17.2°C and minimum temperatures by 11.0°C.

    This dataset presents the demographic monitoring (growth and survival) of 81 tree species based on repeated stem measurement data from 20, 0.5 ha (100 m x 50 m) permanent moist forest plots in northern Queensland, Australia from 1971 to 2019, as well as four additional plots of 0.1 to 1 ha whose monitoring began in the 2000s. The plots have a rainfall range of 1200 to over 6000 mm, represent eleven vegetation types, six parent materials, and range from 15 m to 1500 m above sea level. Except for minor disturbances associated with selective logging on two plots, the plots were established in old growth forest and all plots have thereafter been protected. Plots were regularly censused and at each census the diameter at breast height (DBH) of all stems ≥10 cm DBH were recorded. We only report the data for the 81 species studied in Bauman et al. 2022 (Nature), here. We also provide the climatology of these plots as well as the temperature, vapour pressure deficit, and maximum climatological water deficit of all intervals separating consecutive censuses, as used in the analyses of Bauman et al. 2022.

    <p>This dataset contains audio files for Litchfield Savanna SuperSite. Litchfield Savanna SuperSite was established in 2013 in Litchfield National Park. Site selection was influenced by the history of long-term monitoring work undertaken in this area by the Darwin Centre for Bushfire Research (formerly Bushfires NT). The core 1 ha plot is dominated by <em>Eucalyptus miniata</em> and <em>Eucalyptus tetrodonta</em>. The site is representative of the dominant ecosystem type across northern Australia: frequently burnt tropical savanna in high rainfall areas.

    <p>This dataset contains audio files for TERN Calperum Mallee SuperSite. Long-term recordings of the environment can be used to identify sound sources of interest, characterise the soundscape, aid in the assessment of fauna biodiversity, monitor temporal trends and track environmental changes.</p> <p>The site was established in 2010 and is located on Calperum Station, near Renmark, in South Australia. The property was a pastoral grazing lease for nearly 150 years, and suffered grazing-induced modifications to its ecosystems that are now being actively restored following removal of sheep in 1994. The area includes mallee woodlands and riverine vegetation. A significant amount of the mallee woodlands was burnt in January 2014. The mallee species are multi-stemmed eucalyptus trees (<em>Eucalyptus dumosa</em>, <em>E. incrassata</em>, <em>E. oleosa</em> and <em>E. socialis</em>) while the sparsely distributed mid-storey species come from <em>Eremophila</em>, <em>Hakea</em>, <em>Olearia</em>, <em>Senna</em> and <em>Melaleuca</em> genera. The spaced understory is predominately clumps of spiny grass (<em>Triodia spp.</em>).

    <p>This dataset contains audio files for TERN Cumberland Plain Woodland SuperSite. Long-term recordings of the environment can be used to identify sound sources of interest, characterise the soundscape, aid in the assessment of fauna biodiversity, monitor temporal trends and track environmental changes.</p> <p>Cumberland Plain Woodland SuperSite was established in 2012 in a protected remnant of Shale Gravel Transition Forest, located on the Hawkesbury Campus of the University of Western Sydney in New South Wales. The vegetation at the site is dominated by <em>Eucalyptus moluccana</em> and <em>E. fibrosa</em>, which have hosted a population of mistletoe (<em>Amyema miquelii</em>); a subcanopy of <em>Melaleuca decora</em> is visible in some gaps. The ecosystem is subject to pressure from altered fire regimes, urban development, conversion to agriculture and extreme climate events. However, the forest patch at the site is in excellent condition with the exception of edge effects. For additional site information, see https://www.tern.org.au/tern-observatory/tern-ecosystem-processes/cumberland-plain-supersite/.</p> <p>In 2011 an acoustic recorder was set up to collect audio data for a total of 12 hours per day, split between six hours around dawn and six hours around dusk. A second recorder was added in 2012, and two more were added in 2014. The recording schedule aimed at capturing morning and evening bird choruses while minimizing memory and battery requirements.
