Evidence for divergence between sympatric stone charr and Dolly Varden along unique environmental gradients in Kamchatka.Nikolai Melnik, Grigorii Markevich, Eric Taylor, Evgeny Esin & Aleksey Loktyushkin
Here we describe the biological and ecological differences between partially anadromous Dolly Varden and riverine stone charr distributed in the Kamchatka River middle course. Endemic stone charr, being the ambush predator, is defined by the accelerated growth and prolonged lifespan, robust body and large mouth, as well as specific marble colouration since an early age. The significant restriction in gene flow between the stone charr and benthos-eating Dolly Varden was supported by an allelic distribution...
Trait-dependent diversification in angiosperms: Patterns, models and dataAndrew Helmstetter, Rosana Zenil-Ferguson, Hervé Sauquet, Sarah Otto, Marcos Méndez, Mario Vallejo-Marin, Jürg Schönenberger, Concetta Burgarella, Bruce Anderson, Hugo De Boer, Sylvain Glemin & Jos Käfer
Variation in species richness across the tree of life, accompanied by the incredible variety of ecological and morphological characteristics found in nature, has inspired many studies to link traits with species diversification. Angiosperms are a highly diverse group that has fundamentally shaped life on earth since the Cretaceous and illustrate how species diversification affects ecosystem functioning. Numerous traits and processes have been linked to differences in species richness within this group, but we know little...
Do ecological specialization and functional traits explain the abundance–frequency relationship? Arable weeds as a case studyGuillaume Fried, Laura Armengot, Jonathan Storkey, Bérenger Bourgeois, Sabrina Gaba, Cyrille Violle & François Munoz
Aim: The abundance-frequency relationship (AFR) is among the most-investigated pattern in biogeography, yet the relative contributions of niche-based processes related to ecological strategies, and of neutral processes related to spatial colonization-extinction dynamics, remains uncertain. Here, we tested the influences of ecological specialization and functional traits on local abundance and regional frequency, to determine the contribution of niche-based processes. Location: France and the UK. Taxon: Vascular plants. Methods: We used two arable weed surveys covering 1544...
Data from: Pulled diversification rates, lineages-through-time plots and modern macroevolutionary modellingAndrew Helmstetter
Estimating time-dependent rates of speciation and extinction from dated phylogenetic trees of extant species (timetrees), and determining how and why they vary, is key to understanding how ecological and evolutionary processes shape biodiversity. Due to an increasing availability of phylogenetic trees, a growing number of process-based methods relying on the birth-death model have been developed in the last decade to address a variety of questions in macroevolution. However, this methodological progress has regularly been criticised...
