Mucilages and polysaccharides in Ziziphus species (Rhamnaceae): localization, composition and physiological roles during drought‐stress
TL;DR: In Ziziphus species, growing in environments with erratic rainfall, the primary role of foliar mucilage and glucans, rather than as hydraulic capacitors, may be as sources for the remobilization of solutes for osmotic adjustment, thus enabling more effective water uptake and assimilate redistribution into roots and stems prior to defoliation as the drought-stress intensified.

Archaeological charcoal as a window on palaeovegetation and wood-use during the Middle Stone Age at Sibudu Cave
TL;DR: In this paper, Allott et al. analysed the charcoal from Middle Stone Age layers in Sibudu Cave and found evidence for environmental change and wood selection during the Last Glacial.

Evolution in the proteaceae
TL;DR: The characters of the ancestral "Proto-Proteaceae" are postulated and an evolutionary scheme of probable relationships of subfamilies, tribes, and genera is put forward, but formal taxonomic rearrangement is deferred for a later publication.

A survey of root pressures in vines of a tropical lowland forest
TL;DR: A root pressure mechanism to reverse embolisms in stem xylem could apply to some but not to most of the climbing plants that were studied, as well as three members of the Dilleniaceae.

Host Range of Generalist Caterpillars: Trenching Permits Feeding on Plants with Secretory Canals
TL;DR: It is confirmed that armyworms could feed on plants bearing secretory canals if the larvae were capable of trenching, and the effectiveness of canal—borne exudates as a defense is dependent upon the behavioral capabilities of the herbivore.
