Patterns and Drivers of Phylogenetic Beta Diversity in the Forests and Savannas of Africa

open access: yesJournal of Biogeography, EarlyView.
ABSTRACT Aim Studying beta diversity, or the variation in species composition among communities, can give insights into plant community assembly over space and time. If different biomes show contrasting large‐scale beta‐diversity patterns, this can indicate divergent evolutionary histories or ecological processes that then drive species turnover among ...

What Are the Phylogenetic Limits to Pollinator Diversity?

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT Although huge progress has been made over the past 200 years in identifying the diversity of pollinators of angiosperms and other plants, new discoveries continue to be made each year, especially in tropical areas and in the fossil record. In this perspective article I address the following questions: Just how diverse are the pollinators and ...

The Australian Plant Breeder's Rights Act 1994 (Cth) and how it is used for Australian native plants

open access: yesThe Journal of World Intellectual Property, EarlyView.
Abstract With increasing interest in intellectual property relating to plants, it is timely to assess the use of Plant Breeder's Rights (PBRs) in Australia for native plants, with tens of thousands of native plants nearly all of which are endemic and many with known uses.

Disruption and irruption shape genetic variation and population structure of the common rock‐rat in north‐western Australia

open access: yesJournal of Zoology, EarlyView.
The most abundant and widespread of Australia's rock‐rats shows marked genetic diversity, with the Great Sandy Desert marking a long‐standing genetic dichotomy between populations in the monsoonal and arid biomes. Genetically depauperate relictual island populations formed from 10 ky bp are divergent but nonetheless align with mainland cognates, and ...
