Abstract

Why are some traits and trait combinations exceptionally common across the tree of life, whereas others are vanishingly rare? The distribution of trait diversity across a clade at any time depends on the ancestral state of the clade, the rate at which new phenotypes evolve, the differences in speciation and extinction rates across lineages, and whether an equilibrium has been reached. Here we examine the role of transition rates, differential diversification (speciation minus extinction) and non-equilibrium dynamics on the evolutionary history of angiosperms, a clade well known for the abundance of some trait combinations and the rarity of others. Our analysis reveals that three character states (corolla present, bilateral symmetry, reduced stamen number) act synergistically as a key innovation, doubling diversification rates for lineages in which this combination occurs. However, this combination is currently less common than predicted at equilibrium because the individual characters evolve infrequently. Simulations suggest that angiosperms will remain far from the equilibrium frequencies of character states well into the future. Such non-equilibrium dynamics may be common when major innovations evolve rarely, allowing lineages with ancestral forms to persist, and even outnumber those with diversification-enhancing states, for tens of millions of years.

Abstract

Early flowering plants are thought to have been woody species restricted to warm habitats (1-3). This lineage has since radiated into almost every climate, with manifold growth forms (4). As angiosperms spread and climate changed, they evolved mechanisms to cope with episodic freezing. To explore the evolution of traits underpinning the ability to persist in freezing conditions, we assembled a large species-level database of growth habit (woody or herbaceous; 49,064 species), as well as leaf phenology (evergreen or deciduous), diameter of hydraulic conduits (that is, xylem vessels and tracheids) and climate occupancies (exposure to freezing). To model the evolution of species' traits and climate occupancies, we combined these data with an unparalleled dated molecular phylogeny (32,223 species) for land plants. Here we show that woody clades successfully moved into freezing-prone environments by either possessing transport networks of small safe conduits (5) and/or shutting down hydraulic function by dropping leaves during freezing. Herbaceous species largely avoided freezing periods by senescing cheaply constructed aboveground tissue. Growth habit has long been considered labile (6), but we find that growth habit was less labile than climate occupancy. Additionally, freezing environments were largely filled by lineages that had already become herbs or, when remaining woody, already had small conduits (that is, the trait evolved before the climate occupancy). By contrast, most deciduous woody lineages had an evolutionary shift to seasonally shedding their leaves only after exposure to freezing (that is, the climate occupancy evolved before the trait). For angiosperms to inhabit novel cold environments they had to gain new structural and functional trait solutions; our results suggest that many of these solutions were probably acquired before their foray into the cold., Flowering plants (angiosperms) today grow in a vast range of environmental conditions, with this breadth probably related to their diverse morphology and physiology (7). However, early angiosperms are generally thought [...]

Author

Stevens, Peter F.

Abstract

Describes differing concepts of nature held by systematists from 1789-1859, connections between these concepts, and how they saw relationships among groups and made classifications. Discusses what these systematists intended their classifications to represent and how these intentions relate to classifications used by twentieth-century biologists. Cautions against comparing taxa at the same hierarchical rank. Contains 40 references. (PVD)

47. Angiosperm phylogeny poster (APP) – Flowering plant systematics

Author

Cole, Theodor C H, Hilger, Hartmut H, and Stevens, Peter F

Abstract

The "Angiosperm Phylogeny Poster – Flowering Plant Systematics" is an educational tool presenting an overview of the evolutionary relationships among flowering plants according to APG IV and APweb as of 2016. The phylogenetic tree depicts the 64 orders and the majority of the 416 families, listing the main apomorphies and plesiomorphies as well as diagnostic and nondiagnostic anatomical, morphological, and phytochemical features for orders and higher levels within the tree. The intuitive color-coding facilitates memorization and teaching. Translations of the poster by internationally renown botanists are now available in 18 languages. Hyperlinks to APweb (Peter F. Stevens, Missouri Botanical Garden) are provided for the orders and higher ranks. This is one in a series of three educational posters on the phylogeny of land plants: Poster 1: "Angiosperms", Poster 2: "Tracheophytes: Lycophytes, Ferns, Gymnosperms", Poster 3: "Bryophytes: Liverworts, Mosses, Hornworts".

Abstract

The Melbourne Congress of 2011 authorized a Special Committeeon Registration of Algal and Plant Names (including fossils), whichwas established the following year (Wilson in Taxon 61: 878–879.2012). Its explicit mandate was “to consider what would be involved inregistering algal and plant names (including fossils), using a procedureanalogous to that for fungal names agreed upon in Melbourne andincluded in the Code as Art. 42”, but expectations at the NomenclatureSection in Melbourne went farther than that. There was the hope thatregistration systems for at least some of the main groups would soonbe set up, to be used and tested on a voluntary basis and, if found tobe generally accepted, would persuade the subsequent Congress inShenzhen, in 2017, to declare registration of new names an additionalrequirement for valid publication.
