Significant gaps remain in understanding the response of plant reproduction to environmental change. This is partly because measuring reproduction in long‐lived plants requires direct observation over many years and such datasets have rarely been made publicly available. Here we introduce MASTREE+, a data set that collates reproductive time‐series data from across the globe and makes these data freely available to the communit...
Direct and indirect effects of climate on richness drive the latitudinal diversity gradient in forest treesNARA Subscribed
Climate is widely recognised as an important determinant of the latitudinal diversity gradient. However, most existing studies make no distinction between direct and indirect effects of climate, which substantially hinders our understanding of how climate constrains biodiversity globally. Using data from 35 large forest plots, we test hypothesised relationships amongst climate, topography, forest structural attributes (stem ab...
Petrogenesis and tectonic setting of bimodal volcanism in the Sakoli Mobile Belt, Central Indian shieldNARA Subscribed
The Sakoli Mobile Belt comprises bimodal volcanic rocks that include metabasalt, rhyolite, tuffs, and epiclastic rocks with metapelites, quartzite, arkose, conglomerate, and banded iron formation (BIF). Mafic volcanic rocks are tholeiitic to quartz‐tholeiitic with normative quartz and hypersthene. SiO 2 shows a large compositional gap between the basic and acidic volcanics, depicting their bimodal nature. Both the volcanics ha...
Sexual reproduction in field populations of the facultative apomict, Hieracium pilosellaNARA Subscribed
Hand pollination under New Zealand field conditions of capitula from each of six populations of Hieracium pilosella (maternal parent) with the closely related but morphologically distinct H. aurantiacum produced F 1 hybrids in every case. The frequency of F 1 hybrid offspring among the populations ranged from 0.2 to 21.6%. Involucral bract characteristics, leaf shape, and petal colour were the most useful characters for identi...
