In severely phosphorus (P)-impoverished environments, plants have evolved to use P very efficiently. Yet, it is unclear how P allocation in leaves contributes to their photosynthetic P-use efficiency (PPUE) and position along the leaf economics spectrum (LES). We address this question in 10 species of Banksia and Hakea, two highly P-efficient Proteaceae genera.

- The study examines how the thickness of low-density polyethylene (LDPE) films affects the release rate of phthalic acid esters (PAEs), as well as their structural integrity and production efficiency in agriculture.
- Aging tests on LDPE films with varying thicknesses (0.006 to 0.015 mm) showed that thicker films had significantly less damage after exposure, with the most damage in the thinnest film (32.2% vs. 3.5% in the thickest).
- Thicker LDPE films also resulted in a lower average release rate of PAEs and improved soil water storage and thermal conditions, suggesting that increasing film thickness can enhance production efficiency while reducing environmental risks in arid regions.
South-western Australia is a global biodiversity hotspot and has some of the oldest and most phosphorus (P)-impoverished soils in the world. Proteaceae is one of the dominant P-efficient plant families there, but it is unknown how leaf P concentrations and foliar P allocation of Proteaceae and coexisting dominant plant families vary between seasons and habitats. To investigate this, we selected 18 species from Proteaceae, Myrtaceae and Fabaceae, six from each family, in two habitats from Alison Baird Reserve (32°1'19''S 15°58'52''E) in Western Australia.

- Biodegradable (Bio) plastic films are seen as better alternatives to traditional LDPE films to reduce plastic waste in agriculture, but evidence of their effectiveness is lacking.
- A study in a maize field showed that Bio films degrade by 41.1%, while LDPE films do not degrade at all, which increases microplastic presence in the soil.
- The presence of plastic residues negatively impacted soil structure by lowering macro-aggregates and changing nitrogen and carbon content, pointing out significant flaws in using Bio films in agriculture.
[Impact of habitats on rodent-mediated seed fates of Quercus aliena var. acuteserrata.].

Disturbance is the driving force of forest succession, which can change forest structure and surface vegetation. Disturbance also affects rodent-mediated seed dispersal. In this study, numbered plastic tags were used to examine the responses of rodent dispersal behavior to the fates of Quercus aliena var.
