The article informs about the approaches with drones for restoring biodiverse native vegetation under Land degradation poses a significant threat to the health and integrity of native ecosystems. Topics include require restoration are remote or have difficult-to-access terrain, further complicating restoration efforts; and seed broadcasting methods have the potential to reduce labour and facility maintenance costs.

The article focuses on the steps taken to reduce the impact of mammal decline on the ecosystem in the arid regions of Australia, such as reintroduction of mammals such as bettongs, creation of microsites, and improved leaf litter capture and decomposition for seedling germination. Topics discussed include study on myrmecochory where ants act as seed predators, role of mammals on the increase in shrubs, and importance of vegetation dynamics in arid zones.

The purpose of this study was to investigate burnout symptoms among public school music educators (N = 101) using the Maslach Burnout Inventory (MBI) and to determine potential demographic and job related factors that may be associated with burnout using the Demographic and Data Sheet (DDS) questionnaire. Based on multiple regression analyses it was found that the DDS variables; work load and time to complete the work, desire to change professional careers, contentment with job, unclear goals from administration, and lack of personnel goals in career plans, lack of recognition by students, and lack of cooperation among teachers in the district outside the area of music, significantly contributed to the variance in the regression models and were determined to be reliable predictors of burnout as measured by the MBI.

The purpose of this study was to assess classroom environments, as measured by the Classroom Environment Scale, Form R (CESR) and as perceived by high school instrumental and choral students and teachers (N= 1,843) in performing ensembles, to determine whether any significant differences existed between CESR subject scores according to musical achievement (contest ratings), status (teacher or student), sex, or type of performing group (instrumental or choral). Statistical analysis revealed significant differences in all these areas.

Vegetation cover is fundamental in the formation and maintenance of geomorphological features in dune systems. In arid Australia, increased woody shrub cover has been linked to removal of the apex predator (Dingoes, Canis dingo) via subsequent trophic cascades. We ask whether this increase in shrubs can be linked to altered physical characteristics of the dunes. We used drone-based remote sensing to measure shrub density and construct three-dimensional models of dune morphology. Dunes had significantly different physical characteristics either side of the ‘dingo-proof fence’, inside which dingoes are systematically eradicated and shrub density is higher over vast spatial extents. Generalized additive models revealed that dunes with increased shrub density were higher, differently shaped and more variable in height profile. We propose that low shrub density induces aeolian and sedimentary processes that result in greater surface erosion and sediment transport, whereas high shrub density promotes dune stability. We speculate that increased vegetation cover acts to push dunes towards an alternate stable state, where climatic variation no longer has a significant effect on their morphodynamic state within the bi-stable state model. Our study provides evidence that anthropogenically induced trophic cascades can indirectly lead to large-scale changes in landscape geomorphology.
