Repeated upslope biome shifts in Saxifraga during late-Cenozoic climate cooling.
Mountains are among the most biodiverse places on Earth, and plant lineages that inhabit them have some of the highest speciation rates ever recorded. Plant diversity within the alpine zone - the elevation above which trees cannot grow—contributes significantly to overall diversity within mountain systems, but the origins of alpine... -

Precipitation is the main axis of tropical plant phylogenetic turnover across space and time.
Early natural historians—Comte de Buffon, von Humboldt, and De Candolle—established environment and geography as two principal axes determining the distribution of groups of organisms, laying the foundations for biogeography over the subsequent 200 years, yet the relative importance of these two axes remains unresolved. Leveraging phylogenomic and global species distribution... -

Landscape dynamics and diversification of the megadiverse South American freshwater fish fauna.
Landscape dynamics are widely thought to govern the tempo and mode of continental radiations, yet the effects of river network rearrangements on dispersal and lineage diversification remain poorly understood. We integrated an unprecedented occurrence dataset of 4,967 species with a newly compiled, time-calibrated phylogeny of South American freshwater fishes—the most... -

Barking up the wrong tree: the dangers of taxonomic misidentification in molecular phylogenetic studies.
– is a Brazilian endemic genus that has sat uncomfortably in Convolvulaceae where it was placed due to an enlarged and adnate fruit bract typical of . A recent molecular phylogeny suggested that two of its five morphologically almost identical species actually belong to two different families, Malpighiaceae (superrosids) and... -

Evolutionary history, traits, and weediness in Digitaria (Poaceae: Panicoideae).
Digitaria is a large pantropical genus, which includes a number of economically problematic agricultural weeds. Difficulties in species identification and the circumscription of the genus have previously hindered progress in understanding its evolution and developing a stable classification. We investigate the evolutionary history of Digitaria by combining two approaches: (i)... -

Tribe Shoreae (Dipterocarpaceae subfamily Dipterocarpoideae) Finally Dissected.
The dipterocarp tribe Shoreae, perhaps more than any other members of this elegant family of often giant emergent trees, is familiar to all who visit the once ubiquitous lowland forests of tropical Asia. Timbers of the genus comprised the bulk of hardwood traded on international markets for thirty years, since...Ashton, P. S. ; Heckenhauer, J.

The origin of modern patterns of continental diversity in Mauritiinae palms: the Neotropical museum and the Afrotropical graveyard.
While the latitudinal diversity gradient has received much attention, biodiversity and species richness also vary between continents across similar latitudes. Fossil information can be used to understand the evolutionary mechanisms that generated such variation between continents of similar latitudes. We integrated fossil data into a phylogenetic analysis of the Mauritiinae... -

“Manisa bozaka” or “Counting grass”: Global Grassy Group guide to understanding and measuring the functional and taxonomic composition of ground layer plants.
Grassy biomes span more than 40% of the global land surface and are central to people, biodiversity and Earth System functioning. There is however limited standardised measurement of herbaceous taxonomic and functional composition in grassy biomes that inhibits the development of a comparative understanding of grassy biomes among geographic regions.... -

Diversification dynamics in the Neotropics through time, clades, and biogeographic regions.
The origins and evolution of the outstanding Neotropical biodiversity are a matter of intense debate. A comprehensive understanding is hindered by the lack of deep-time comparative data across wide phylogenetic and ecological contexts. Here, we quantify the prevailing diversification trajectories and drivers of Neotropical diversification in a sample of 150... -

Savanna tree evolutionary ages inform the reconstruction of the paleoenvironment of our hominin ancestors.
Ideas on hominin evolution have long invoked the emergence from forests into open habitats as generating selection for traits such as bipedalism and dietary shifts. Though controversial, the savanna hypothesis continues to motivate research into the palaeo-environments of Africa. Reconstruction of these ancient environments has depended heavily on carbon isotopic... -

Phylogenetic relationships of Fabales, the effect of outgroups on Fabales topology and the evolution of keel flowers within the order.
Fabales is a cosmopolitan angiosperm order which consists of four families, Leguminosae (Fabaceae), Polygalaceae, Surianaceae and Quillajaceae. Despite the great interest of botanists, a convincing phylogeny of the order is still not available because almost every phylogenetic study reveals a different scheme of relationships amongst families of the order. Therefore,...Aygoren Uluer, Deniz
