A dated phylogeny shows Plio-Pleistocene climates spurred evolution of antibrowsing defences in the New Zealand flora.

Some plant traits may be legacies of coevolution with extinct megafauna. One example is the convergent evolution of 'divaricate' cage architectures in many New Zealand lineages, interpreted as a response to recently extinct flightless avian browsers whose ancestors arrived during the Paleogene period. Although experiments have confirmed that divaricate habit deters extant browsers, its abundance on frosty, droughty sites appears consistent with an earlier interpretation as a response to cold, dry Plio-Pleistocene climates.

Comparing diversity of fungi from living leaves using culturing and high-throughput environmental sequencing.

High-throughput sequencing technologies using amplicon approaches have changed the way that studies investigating fungal distribution are undertaken. These powerful and time-efficient technologies have the potential for the first time to accurately map fungal distributions across landscapes or changes in diversity across ecological or biological gradients of interest. There is no requirement for a fungus to form a fruiting body to be detected, and both culturable and nonculturable organisms can be detected.

Systematics of Kirk (Poaceae, Agrostidinae) - an endemic, threatened New Zealand grass genus.

A new species of the New Zealand endemic grass , is described. The new species is segregated from and compared with and . occurs mostly in lightly shaded areas of seasonally dry alluvial forest.

Pulling the sting out of nettle systematics - A comprehensive phylogeny of the genus Urtica L. (Urticaceae).

The genus Urtica L. is subcosmopolitan, found on all continents (except Antarctica) and most extratropical islands and ranges from Alaska to Patagonia, Spitzbergen to the Cape and Camtschatka to the subantarctic islands. However, throughout its geographical range morphologically nearly indistinguishable species are found alongside morphologically quite disparate species, with the overall diversity of morphological characters extremely limited.

When do plant radiations influence community assembly? The importance of historical contingency in the race for niche space.

Plant radiations are widespread but their influence on community assembly has rarely been investigated. Theory and some evidence suggest that radiations can allow lineages to monopolize niche space when founding species arrive early into new bioclimatic regions and exploit ecological opportunities. These early radiations may subsequently reduce niche availability and dampen diversification of later arrivals.
