Data from: The role of functional strategies in global plant distribution
<p>Understanding the determinants of species distributions is a central topic in ecology. Competition, stress tolerance and colonization, respectively represented by Grime's competitor (C), stress-tolerator (S) and ruderal (R) schemes, are three important functions that interactively influence plant distributions. In this study, we compiled a dataset of 2645 vascular plant species to explore the roles of the CSR strategies in global plant distribution. We analyzed the associations between the CSR scores and species range size with phylogenetic generalized least square (PGLS) models and phylogenetic path analysis, both of which accounted for the effects of species phylogenetic relatedness, longevity, and growth form. The functional strategy-range size associations differed across different distributional ranges and growth forms. Specifically, species global and native range sizes were positively associated with the R score; species naturalized range size was positively associated with the C score; and all range-size measurements were negatively associated with the S score. These patterns were mostly driven by herbs but not shrubs or trees. For species global and native-range distributions, the patterns of shrubs were even opposite to those of herbs. Our work emphasizes the importance of distinguishing the functional strategy-distribution associations between different distributional ranges and growth forms for ecosystem conservation and invasion risk prediction, because of the trade-offs among the CSR strategies.</p>
Data from: Functional traits explain variation in plant life history strategies
Ecologists seek general explanations for the dramatic variation in species abundances in space and time. An increasingly popular solution is to predict species distributions, dynamics and responses to environmental change based on easily measured anatomical and morphological traits. Trait-based approaches assume that simple functional traits influence fitness and life history evolution, but rigorous tests of this assumption are lacking because they require quantitative information about the full life-cycles of many species representing different life histories. Here we link a global traits database with empirical matrix population models for 222 species and report strong relationships between functional traits and plant life histories. Species with large seeds, long-lived leaves, or dense wood have slow life histories, with mean fitness (i.e. population growth rates) more strongly influenced by survival than by growth or fecundity, compared to fast life history species with small seeds, short-lived leaves, or soft wood. In contrast to measures of demographic contributions to fitness based on whole life-cycles, analyses focused on raw demographic rates may underestimate the strength of association between traits and mean fitness. Our results help establish the physiological basis for plant life history evolution and show the potential for trait-based approaches in population dynamics.
Data from: Conserving phylogenetic diversity can be a poor strategy for conserving functional diversity
For decades, academic biologists have advocated for making conservation decisions in light of evolutionary history. Specifically, they suggest that policy makers should prioritize conserving phylogenetically diverse assemblages. The most prominent argument is that conserving phylogenetic diversity (PD) will also conserve diversity in traits and features (functional diversity [FD]), which may be valuable for a number of reasons. The claim that PD-maximized ("maxPD") sets of taxa will also have high FD is often taken at face value and in cases where researchers have actually tested it, they have done so by measuring the phylogenetic signal in ecologically important functional traits. The rationale is that if traits closely mirror phylogeny, then saving the maxPD set of taxa will tend to maximize FD and if traits do not have phylogenetic structure, then saving the maxPD set of taxa will be no better at capturing FD than criteria that ignore PD. Here, we suggest that measuring the phylogenetic signal in traits is uninformative for evaluating the effectiveness of using PD in conservation. We evolve traits under several different models and, for the first time, directly compare the FD of a set of taxa that maximize PD to the FD of a random set of the same size. Under many common models of trait evolution and tree shapes, conserving the maxPD set of taxa will conserve more FD than conserving a random set of the same size. However, this result cannot be generalized to other classes of models. We find that under biologically plausible scenarios, using PD to select species can actually lead to less FD compared with a random set. Critically, this can occur even when there is phylogenetic signal in the traits. Predicting exactly when we expect using PD to be a good strategy for conserving FD is challenging, as it depends on complex interactions between tree shape and the assumptions of the evolutionary model. Nonetheless, if our goal is to maintain trait diversity, the fact that conserving taxa based on PD will not reliably conserve at least as much FD as choosing randomly raises serious concerns about the general utility of PD in conservation.
Data from: Shifts in plant functional strategies over the course of wheat domestication
1. Human selection, changes in environmental conditions and management practices drove the phenotypic trajectory of crops during domestication. The characterization of the crop domestication syndrome lies mostly on reproductive characters. However, biophysical and ecophysiological constraints during vegetative growth are also at play and can strongly impact crop phenotypes. It has been argued that a broadened examination of crop phenotypes through a functional trait-based lens should improve our understanding of the domestication syndrome. 2. We used a collection of 39 genotypes representative of key steps during tetraploid wheat domestication, and grew them in a common garden experiment. We quantified the vegetative phenotype of each genotype through the measurements of 13 functional traits related to root, leaf and whole-plant dimensions. 3. In modern cultivars, compared to ancestral forms, leaf longevity was shorter while net photosynthetic rate, leaf production rate and nitrogen content were higher. Modern cultivars had a shallower root system and exhibited a larger proportion of fine roots, preferring to invest biomass above rather than below ground. We found ancestral forms to be integrated phenotypes characterized by coordination between above- and below-ground functioning. Conversely, in modern forms, human selection appeared to have broken this coordination and to have generated a new type of network of trait covariations. 4. Synthesis and applications. The examination of leaf, root, and whole-plant traits of wheat accessions indicated a strong shift in plant functional strategies over the course of domestication. Elite genotypes tended to better optimize resource-use acquisition strategies than ancestral ones. The characterization of the crop phenotype based on vegetative traits thus suggests a much more complete domestication syndrome. Our findings highlight the benefits of using a functional trait-based characterization of crop phenotypes to document the extent of domestication syndrome and to further advance the agroecological management of cereals.10-Oct-2017
Functional changes in fortified places: Strategy and defensive architecture in the Medieval and Early Modern Era
<p><strong>Data for Scott Kirk's Doctoral Dissertation.</strong></p> <p><strong>Dissertation Abstract:</strong></p> <p>Defined as fortified elite Houses, castles are a cross-cultural phenomenon, best understood by pairing Niche Construction Theory (NCT) with the Lévi-Straussian concept of the House. NCT can be thought of as a theory of the built environment, thus the material configuration of castles and their placement on the landscape reflect elite socio-cultural requirements. My dissertation asks: How do changes in castle morphology and landscape placement reflect broad shifts in function diachronically and cross-culturally?</p> <p>Wherever elites are militarized, castles typically appear. Similarities in castle design and function are best understood through anthropological frameworks and comparative, interdisciplinary approaches. Using a sample of castles from medieval European, western colonial, and nonwestern societies, I hypothesize that: (1) castle building is a common, cross-cultural behavior, (2) geography and the environment constrain castle location, allowing for a landscape-based typology of castles, and (3) changes in castle placement and design reflect large-scale social competition between elites.</p> <p>These hypotheses contradict much of the current regionally-focused work in castle studies, which are often grounded in national ideologies. Early 20th century studies were more aligned with my hypotheses. Revisiting these earlier investigations, my dissertation uses anthropological theories within an interdisciplinary approach. It combines architectural, statistical, and geospatial analyses to quantitatively test how similar castle placement and co-occurring architectural features are cross-culturally, and how these attributes change over time in relation to elite competition.</p> <p>This research has general and theoretical significance for assessing mechanisms of elite status reinforcement, behavior, and decision-making across space and time. Building a typology that characterizes castles as resource control points, examining how similar architectural features appear in disparate cultures, and exploring social change driven by elite competition, my dissertation takes aim at nationalistic policies by illustrating cross-cultural similarities that are applicable to the modern world in terms of increasing wealth disparities and socioeconomic inequality.</p>
