Clades That Frequently Accumulate Metals Do Not Have Low Abundance in the Tropical Forests of Sulawesi, Indonesia Open
In diverse tropical communities, individuals with more distinct traits typically have lower abundance. In many tropical communities, the most distinct plants with regard to their stoichiometry are metal hyperaccumulators. The Celastrales, …

Disentangling evolutionary, geometric and ecological components of the elevational gradient of diversity Open
Despite the high importance and risk of mountain ecosystems in global biodiversity conservation, the mechanisms giving rise to and maintaining elevational biodiversity gradients are poorly understood, limiting predictions of future respons…

From earthquakes to island area: multi‐scale effects upon local diversity Open
Tropical forests occupy small coral atolls to the vast Amazon basin. They occur across bioregions with different geological and climatic history. Differences in area and bioregional history shape species immigration, extinction and diversi…

A new species of Lasjia (Proteaceae) from Sulawesi: Lasjia griseifolia Utteridge & Brambach Open
Summary Lasjia griseifolia Utteridge & Brambach, a member of the Proteaceae, is described and illustrated as a new species from the Indonesian island of Sulawesi. The new species is similar to L. erecta , also from Sulawesi, and morphologi…

Island area, isolation and climate effects upon flower traits in a megadiverse archipelago Open
Aim Flower traits are critical to the mutualistic networks that underpin ecosystem function. However, the broad‐scale drivers of flower traits are unclear. Using the megadiverse islands of Malesia, we test three hypotheses: (1) Flower size…

Environment‐dependent influence of fruit size upon the distribution of the Malesian archipelagic flora Open
Societal Impact Statement We found evidence that larger fruited plant species are more likely to be found in aseasonal wet areas of Malesia. These areas are likely to be impacted by increasing human encroachment, which threatens both large…

Environmental stress influences Malesian Lamiaceae distributions Open
Dual effects of spatial distance and environment shape archipelagic floras. In Malesia, there are multiple environmental stressors associated with increasing uplands, drought, and metal‐rich ultramafic soils. Here, we examine the contrasti…

Safeguarding Imperiled Biodiversity and Evolutionary Processes in the Wallacea Center of Endemism. Open
Wallacea-the meeting point between the Asian and Australian fauna-is one of the world's largest centers of endemism. Twenty-three million years of complex geological history have given rise to a living laboratory for the study of evolution…

Plant species biogeographic origin shapes their current and future distribution on the world's highest island mountain Open
In New Guinea, low elevations are thought to be dominated by plant species with biogeographic origins in Sunda (Borneo, Sumatra, Java, Mainland Asia) and high elevations by species from Sahul (Australia and New Guinea). In regions where fr…

Genomic insights into rapid speciation within the world’s largest tree genus Open
Species radiations have long fascinated biologists, but the contribution of adaptation to observed diversity and speciation is still an open question. Here, we explore this question using the clove genus, Syzygium, the world’s largest genu…

A SURVEY OF ALUMINIUM ACCUMULATION IN EUMACHIA (RUBIACEAE) Open
A useful character for spotting specimens of the pantropical Rubiaceae genus Eumachia is the leaves drying green. The physiological reasons for this are unresolved. We investigated whether the phenomenon is related to the accumulation of a…
