Journal ArticleDOI
Mericarp morphology and its systematic implications for the genus Salvia L. section Hymenosphace Benth. (Lamiaceae) in Turkey
TL;DR: Variation was sufficient to distinguish taxa at species level, including morphologically similar species, and the variation in the nature of surface sculpturing, mericarp shape and size, exocarp cell shape, nature of transverse sections and abscission scar diameter proved useful diagnostic characters.
Journal ArticleDOI
Bioclimatic transect networks: powerful observatories of ecological change
Stefan Caddy-Retalic,Alan N. Andersen,Michael J. Aspinwall,Martin F. Breed,Margaret Byrne,Matthew J. Christmas,Ning Dong,Bradley Evans,Damien A. Fordham,Greg R. Guerin,Ary A. Hoffmann,Alice C. Hughes,Stephen van Leeuwen,Francesca A. McInerney,Suzanne M. Prober,Maurizio Rossetto,Paul D. Rymer,Dorothy A. Steane,Glenda M. Wardle,Glenda M. Wardle,Andrew J. Lowe +20 more
TL;DR: It is argued that replicating and networking transects, along with the introduction of experimental treatments, addresses concerns and can provide a spatiotemporal understanding of past and future climate‐induced changes, which will inform effective management actions for promoting biodiversity resilience.
Journal ArticleDOI
Nutlet morphology in Hemigenia R.Br. and Microcorys R.Br. (Lamiaceae)
TL;DR: A cladistic analysis of nutlet characters suggests both Hemigenia and MicroCorys are polyphyletic, and Microcorys paraphyletic with respect to Westringia Sm.
Journal ArticleDOI
Opportunities for Integrated Ecological Analysis across Inland Australia with Standardised Data from Ausplots Rangelands.
Greg R. Guerin,Ben Sparrow,Andrew Tokmakoff,Anita K. Smyth,Emrys Leitch,Zdravko Baruch,Andrew J. Lowe +6 more
TL;DR: In this article, the authors presented a new dataset from AusPlots Rangelands that enables integrative rangelands analysis due to its geographic scope and standardised methodology, enabling comparison of a suite of metrics including fractional vegetation cover, basal area, and species richness, diversity, and composition.
Journal ArticleDOI
Weed abundance is positively correlated with native plant diversity in grasslands of southern Australia.
TL;DR: The positive relationships existing between native and exotic plant species in high-moderately disturbed grasslands of South Australia are most likely due to facilitation through different strategies in occupation of space given that the effect of habitat suitability was controlled for by including environmental and disturbance factors.
