There is an urgent need to synthesize the state of our knowledge on plant responses climate. The availability open-access data provide opportunities examine quantitative generalizations regarding which biomes and species are most responsive climate drivers. Here, we time series structured population models from 162 populations 62 plants, mostly herbaceous temperate biomes, link growth rates (λ) precipitation temperature We expect: (1) more pronounced demographic than temperature, especially...
Abstract Aim We mapped global patterns of tree phylogenetic endemism (PE) to identify hotspots and test hypotheses about possible drivers. Specifically, we tested related current climate, geographical characteristics historical conditions assessed their relative importance in shaping PE patterns. Location Global. Time period used the present distribution trees, predictors covering from mid‐Miocene present. Major taxa studied All seed‐bearing trees. Methods compiled distributions for 58,542...
Abstract Discrete time structured population projection models are an important tool for studying dynamics. Within this field, Integral Projection Models (IPMs) have become a popular method populations by continuously distributed traits (e.g. height, weight). Databases of discrete time, state models, example DATLife (life tables) and COMPADRE & COMADRE (matrix models), made quantitative syntheses straightforward to implement. These efforts allow researchers address questions in both...
Abstract Integral projection models (IPMs) are an important tool for studying the dynamics of populations structured by one or more continuous traits (e.g. size, height, body mass). Researchers use IPMs to investigate questions ranging from linking drivers population dynamics, planning conservation and management strategies, quantifying selective pressures in natural populations. The popularity stage‐structured has been supported R scripts packages IPMpack , popbio popdemo lefko3 ) aimed at...
Summary Matrix population models (MPMs) are an important tool for biologists seeking to understand the causes and consequences of variation in vital rates (e.g., survival, reproduction) across life cycles. Empirical MPMs describe age- or stage-structured demography organisms usually represent history a during particular time frame at specific geographic location. The COMPADRE Plant Database COMADRE Animal most extensive resources MPM data, collectively containing >12,000 individual...

Abstract Plant population ecologists strive to understand how environmental drivers influence demographic vital rates and thus dynamics. Hundreds of studies have collected data used matrix and/or integral projection models quantify lifetime fitness dynamics plants. However, most these focused on native plant species, there is a need for more alien Further, few plants experimentally manipulated in order the mechanisms that allow species positive growth. A synthetic understanding will only be...
Abstract Aims Trees dominate the biomass in many ecosystems and are essential for ecosystem functioning human well‐being. They also one of best‐studied functional groups plants, with vast amounts biodiversity data available scattered sources. We here aim to illustrate that an efficient integration these could produce a more holistic understanding vegetation. Methods To assess extent potential integration, we use key databases plant to: (a) obtain list tree species their distributions; (b)...
Carpobrotus species are harmful invaders to coastal areas throughout the world, particularly in Mediterranean habitats. Demographic models ideally suited identify and understand population processes stages life cycle of that could be most effectively targeted with management. However, parameterizing these has been limited by difficulty accessing cliff-side locations where its populations typically found, as well accurately measuring growth spread individuals, which form large, dense mats....
The genus Carpobrotus N.E.Br. comprises between 12 and 25 species, most of which are native to South Africa. Some species considered among the damaging invasive in coastal dune systems worldwide. In their introduced areas, these represent a serious threat significantly impact soil conditions geochemical processes. Despite being well studied, taxonomy remains problematic, as complex that hybridize easily difficult distinguish from each other. To explore population genetic structure (i.e., C....
Several invasion hypotheses predict a positive association between phylogenetic and functional distinctiveness of aliens their performance, leading to the idea that distinct compete less with resident communities. However, synthetic pattern relationships alien performance direct tests competition as driving mechanism have not been forthcoming. This is likely because different patterns are observed at spatial grains, trait information often incomplete, need for experiments measure demographic...
spind is an R package aiming to provide a useful toolkit account for spatial dependence in the analysis of lattice data. Grid-based data sets modelling often exhibit dependence, i.e. values sampled at nearby locations are more similar than those further apart. methods, described here, take this kind two-dimensional into and sensitive its variation across different scales. Methods presented autocorrelation based on two fundamentally approaches generalised estimating equations as well...

Abstract Population dynamics play a central role in the historical and current development of fundamental applied ecological science. The nascent culture open data promises to increase value population studies field ecology. However, synthesis is constrained by difficulty identifying relevant datasets, heterogeneity available access raw (as opposed aggregated or derived) observations. To obviate these issues, we built relational database, popler , its R client, library "popler". accommodates...
ABSTRACT Approximately 25 % of mammals are threatened globally with extinction, a risk that is amplified under climate change 1 . Persistence determined by the combined effects climatic factors on multiple demographic rates (survival, development, reproduction), and hence, population dynamics 2 Thus, to quantify which species places Earth most vulnerable climate-driven global understanding how respond needed 3 We synthesise information such responses in terrestrial mammals, where extensive...
