Key Aspects

Nest boxes have been recognised as research and management tools for arboreal marsupials in Australia for over 20 years. We review the published literature with the aim of describing the scope of studies conducted in Australia thus far and providing guidance to future research. We recognise three types of application in research: (1) detection of species, (2) study of a species’ ecology, and (3) investigation of box designs preferred by different species. Several species of arboreal marsupial may be detected more readily in nest boxes than by conventional survey techniques, allowing description of key aspects of their ecology; e.g. feathertail glider (Acrobates pygmaeus), eastern pygmy possum (Cercartetus nanus) and brush-tailed phascogale (Phascogale tapoatafa). Identifying the most favoured nest-box design for any species has implications for detection and management uses of nest boxes. More research is needed but preliminary findings suggest that species prefer narrow entrance holes, while height of the nest box above 3 m may be inconsequential. We recognise three types of management application: (1) species introduction, (2) support of populations of endangered species, and (3) strategic placement such as to enhance habitat connectivity. Currently there have been few attempts to use nest boxes to manage arboreal marsupials but further research is needed to realise their potential as a management tool.

Although nest boxes have considerable application in the research and management of hollow-using arboreal marsupials, few studies have assessed whether species show a preference for particular nest box designs. This study aimed to determine whether the feathertail glider (Acrobates pygmaeus) showed a preference when offered four different designs, each of which had been used in earlier studies. We established one of each design in 45 plots across five locations, spanning north-east New South Wales and south-east Queensland. Feathertail gliders used 34 nest boxes at four locations but avoided a medium-sized rear-entry box with a 45-mm-diameter entrance. No clear preference was shown for three designs with narrow (≤25 mm) entrances. Feathertail gliders used 15 small rear-entry boxes, 10 large slit-entrance boxes and 9 wedge-shaped bat boxes. A slight preference was shown by breeding groups to occur in the non-wedge boxes compared with the wedge boxes. Squirrel gliders (Petaurus norfolcensis) used 51% of medium rear-entry boxes at four locations. This may account for the avoidance of this box design by feathertail gliders at these locations. Breeding and prolonged use of nest boxes by resident feathertail gliders and squirrel gliders at two locations in eucalypt plantations suggest that nest boxes can support local populations of arboreal marsupials where tree hollows are absent or scarce.

The results are reported of a nest-box study conducted in two locations in the mountain ash (Eucalyptus regnans) forests of the Central Highlands of Victoria (south-eastern Australia) to compare usage of different nest-box designs located at different heights in trees. A total of 96 nest boxes was established using a rigorous experimental design – two regions (Powelltown and Toolangi State Forests), two forest age classes (20-year post-logging regrowth and 60-year fire- and salvage-logging regrowth), two nest-box designs (large boxes with large entrance holes and small boxes with small entrance holes), and two heights at which nest boxes were attached to trees (3 m and 8 m above the ground). The study entailed setting out four nest boxes at each of 24 sites to meet the design criteria. Evidence of occupancy by vertebrates was recorded in a total of 19 of 96 boxes on 11 of 24 sites site during regular inspections over more than three years. Thirteen boxes were used by Leadbeater's possum (Gymnobelideus leadbeateri), six by the mountain brushtail possum (Trichosurus cunninghami) and seven by the common ringtail possum (Pseudocheirus peregrinus). The common ringtail possum and mountain brushtail possum were seen only in high–large boxes but Leadbeater's possum used all but the low–large boxes. There was evidence of spatial dependence in usage patterns, with all four boxes at a given site showing signs of eventually being occupied. Only two nest boxes located in mountain ash forest regenerating after the 1939 wildfires were occupied. Relatively limited use of nest boxes supports concerns about the use of a nest box over large scales and long timeframes as an effective recovery tool for species threatened by the loss and subsequent shortage in the numbers of naturally occurring hollows.

Managing the availability of shelter sites is central to the conservation of vertebrate wildlife dependent on tree hollows (cavities) because hollow abundance has been reduced in many landscapes and trees do not typically acquire hollows until they are at least 100 years old. Artificial hollows (nest boxes) provide one option to offset local shortages in tree hollows. However, knowledge of preferred designs is required for this to be effective. We investigated nest box preference by the eastern pygmy-possum (Cercartetus nanus), a small marsupial recognised as threatened across part of its geographic range in eastern Australia. We installed nest boxes of four different designs in each of 30 plots where tree hollows were scarce. Designs showed no significant difference in thermal profile. We captured 223 adult and subadult pygmy-possums within 78% of the 120 boxes. Breeding females used boxes more frequently than adult males and showed a preference among the designs whereas males did not. Females favoured plywood nest boxes over a PVC design offering a horizontal cavity. Use of the PVC design increased when repositioned to present a vertical cavity. Thus, breeding females are selective of the cavities used to rear young, which may limit local population size.

Recovery Program

As hollow-bearing trees become scarcer due to habitat loss, the use of nest boxes as a management tool for hollow-dependent species is likely to increase. However, nest-box use can be variable among species and habitats, and one possible reason may be that nest boxes offer little protection against extreme temperatures compared with natural hollows; this may be particularly important in the tropics. Here, we measured the microclimate of 16 nest boxes, installed as part of a recovery program for an endangered arboreal marsupial, the mahogany glider, during the summer in tropical north Queensland. We also measured the microclimate of 14 naturally occurring refuges (hollows in standing and fallen trees) at the same study sites. Nest boxes were significantly hotter during the day than were natural refuges (either in fallen or standing live trees) and experienced a greater range of temperatures. The most important factors explaining variation in daytime temperature in boxes was box aspect and the amount of canopy cover directly above the box: boxes that faced north, and those with greater canopy cover, were up to 7°C cooler than those that faced south or had little cover. We discuss our results in relation to the use of nest boxes in management plans for arboreal marsupials in the tropics.

Context. Nest boxes provide important nesting, denning and shelter sites for many fauna species worldwide, but we know little about the factors that influence the suitability of nest boxes for particular species. Such information is crucial in urban landscapes where natural hollows are scarce. Aims. The aim of this study was to record the use of nest boxes by sugar gliders (Petaurus breviceps), squirrel gliders (P. norfolcensis) and other fauna in a peri-urban landscape in northern Victoria and examine factors at multiple spatial scales that may influence nest-box use. Methods. We monitored the use of 102 nest boxes over three seasons in 2006. Attributes that may influence nest-box occupancy were measured at five different spatial scales: (i) landscape; (ii) the habitat beyond 20 m of the nest box; (iii) the habitat within 20 m of the nest box; (iv) the tree that the nest box was located in; and (v) the nest box. Key results. At the landscape scale, topography influenced nest-box occupancy with squirrel gliders using boxes in flat or gully areas, and sugar gliders using boxes in gully, mid-slope or ridge areas. For habitat beyond 20 m of the nest box, sugar gliders were more likely to occupy boxes with a higher density of surrounding nest boxes and a higher density of residential dwellings. Within 20 m of the nest box, boxes occupied by sugar gliders were more likely to occur in areas with a higher density of acacia shrubs and lower density of hollow-bearing trees, whereas the presence of acacia did not influence nest-box use by squirrel gliders. At the scale of the nest-box tree, boxes occupied by sugar gliders were more likely to be on smaller trees (based on height and diameter) and on box (e.g. red box Eucalyptus polyanthemos) species. The only nest-box characteristic to have a strong relationship with occupancy was date of establishment, with longer established boxes more likely to be occupied. Conclusions. Our study demonstrates that various factors influence nest-box use at different scales and nest boxes remain an important conservation and management tool in heavily modified landscapes. Implications. Land managers and groups should be aware that nest boxes may help to alleviate some of the negative impacts of the loss of hollow-bearing trees in low density urban areas, but nest-box use will vary depending on landscape context, habitat factors, box design, and the ecological traits of the target species. Each of these factors must be considered to maximise the conservation benefits of nest-box programs.

Cavity-using birds and mammals reliant on nest boxes may be negatively affected by the poor thermal buffering of nest boxes. I investigated whether nest box use by the eastern pygmy-possum (Cercartetus nanus) over a 4-year period was influenced by maximum ambient temperature, which ranged from 15.6 to 34.9°C during survey occasions. Occupancy modelling of 144 site detections over 30 survey occasions suggested that a model that included maximum temperature had little support whereas a model involving time-varying detection (i.e. detection differed across sample occasions) was the most plausible. I also investigated how temperatures in nest boxes and tree hollows varied over the four hottest days of summer, including one day when the temperature reached 40.6°C. Maximum temperatures were 3–4°C cooler in plywood nest boxes and 5–8°C cooler in tree hollows compared with ambient temperatures. Together, these results suggest that eastern pygmy-possums using nest boxes in coastal areas are unlikely to experience heat stress. Cavity-using species are a heterogeneous group such that empirical studies are required to identify those that may be vulnerable to heat stress if nest boxes are used to provide population support.

Sampling Procedures

The etiological agent for novel coronavirus (COVID-19, Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), not only affects the human respiratory system, but also the gastrointestinal tract resulting in gastrointestinal manifestations. The high rate of asymptomatic infected individuals has challenged the estimation of infection spread based on patients’ surveillance, and thus alternative approaches such as wastewater-based epidemiology (WBE) have been proposed. Accordingly, the number of publications on this topic has increased substantially. Thus, this systematic review aimed at providing state-of-the-knowledge on the occurrence and existing methods for sampling procedures, detection/quantification of SARS-CoV-2 in sewage samples, as well as anticipating challenges and providing future research direction to improve the current scientific knowledge. Articles were collected from three scientific databases. Only studies reporting measurements of virus in stool, urine, and wastewater samples were included. Results showed that improving the scientific community’s understanding in these avenues is essential if we are to develop appropriate policy and management tools to address this pandemic pointing particularly towards WBE as a new paradigm in public health. It was also evident that standardized protocols are needed to ensure reproducibility and comparability of outcomes. Areas that require the most improvements are sampling procedures, concentration/enrichment, detection, and quantification of virus in wastewater, as well as positive controls. Results also showed that selecting the most accurate population estimation method for wastewater-based epidemiology studies is still a challenge. While the number of people infected in an area could be approximately estimated based on quantities of virus found in wastewater, these estimates should be cross-checked by other sources of information to draw a more comprehensive conclusion. Finally, wastewater surveillance can be useful as an early warning tool, a management tool, and/or a way for investigating vaccination efficacy and spread of new variants.

The vast majority of works published on Lean focus on the evaluation of tools and/or the strategies needed for its implementation. Although many authors highlight the degree of employee commitment as one of the key aspects of Lean, what has gone largely unnoticed in the literature, is that few studies have examined in-depth the concept of organizational commitment in connection with Lean. With this narrative literature review article, our main objective is (1) to identify and analyze an extensive body of literature that addresses the Lean Manufacturing approach and how it relates to employee commitment, emphasizing affective commitment as the main type of organizational commitment positively associated with Lean, and (2) to highlight the management practices required to encourage this kind of commitment and promote the success and sustainability of Lean. This paper aims to provide a comprehensive overview that can help researchers and practitioners interested in Lean better understand the importance of employee commitment in this type of approach, and as well, to identify related research questions.

Tropical island countries are often highly populated and deliver immense ecosystem service benefits. As human wellbeing depends on these ecosystems, proper management is crucial in the resource-rich tropical lands where there is less related research. Though ecosystem service and biodiversity studies are a promising path to inform the ecosystem management for these mostly developing countries, published evidence of using ecosystem service studies in decision making is lacking. The purpose of this study is to provide an overview of ecosystem services and related research in Sri Lanka, examining trends and gaps in how these studies are conceptualized. Out of the considered 220 peer-reviewed articles, the majority of articles (48.2%) were terrestrial and forest related while coastal ecosystems were considered in 33.2% of studies. In most studies, the ecosystem service category studied was provisioning (31.5%) followed by regulatory service (28.7%). Studies investigating and quantifying ecosystem services, pressures on ecosystems, and their management were fewer compared to studies related to biodiversity or species introduction. Moreover, studies investigating the value of ecosystem services and biodiversity to the communities or involvement of stakeholders in the development of management actions regarding the ecosystem services were rare in Sri Lanka, and an intense focus from future studies in these aspects is timely and necessary.
