Data from: Land use alters trophic redundancy and resource flow through stream food webs

Elliott L. Price, Mirela Sertić Perić, Romero Q. Gustavo & Pavel Kratina
1. The changes to physical and chemical ecosystem characteristics as a response to pervasive and intensifying land use have the potential to alter the consumer-resource interactions and to rewire the flow of energy through entire food webs. 2. We investigated these structural and functional properties of food webs in stream ecosystems distributed across woodland, agricultural and urban areas in the Zagreb region of Croatia. We compared resource availability and consumer diet composition using stable isotope...

Data from: Warming at the population level: effects on age structure, density, and generation cycles.

Alice M. Laughton & Robert J. Knell
The impact of climate change on strongly age-structured populations is poorly understood, despite the central role of temperature in determining developmental rates in ectotherms. Here we examine the effect of warming and its interactions with resource availability on the population dynamics of the pyralid moth Plodia interpunctella, populations of which normally show generation cycles, a consequence of strong and asymmetric age-related competition. . Warming by 3°C above the standard culture temperature led to substantial changes...

Data from: Temperature-dependence of minimum resource requirements alters competitive hierarchies in phytoplankton

Leah Lewington-Pearce, Anita Narwani, Mridul K. Thomas, Colin Kremer, Helena Vogler & Pavel Kratina
1. Resource competition theory is a conceptual framework that provides mechanistic insights into competition and community assembly of species with different resource requirements. However, there has been little exploration of how resource requirements depend on other environmental factors, including temperature. Changes in resource requirements as influenced by environmental temperature would imply that climate warming can alter the outcomes of competition and community assembly. 2. We experimentally demonstrate that environmental temperature alters the minimum light and...

Data from: Shifts along parasite-mutualist continuum are opposed by fundamental trade-offs

Andrew C. Matthews, Lauri Mikonranta & Ben Raymond
Theory suggests that symbionts can readily evolve more parasitic or mutualistic strategies with respect to hosts. However, many symbionts have stable interactions with hosts that improve nutrient assimilation or confer protection from pathogens. We explored the potential for evolution of increased parasitism or decreased parasitism and mutualism in a natural gut symbiosis between larvae of Plutella xylostella and the microbe Enterobacter cloacae. We focused on interactions with the pathogen, Bacillus thuringiensis: selecting for parasitism in...

Data from: Bayesian estimation of species divergence times using correlated quantitative characters

Sandra Álvarez-Carretero, Anjali Goswami, Ziheng Yang & Mario Dos Reis
Discrete morphological data have been widely used to study species evolution, but the use of quantitative (or continuous) morphological characters is less common. Here, we implement a Bayesian method to estimate species divergence times using quantitative characters. Quantitative character evolution is modelled using Brownian diffusion with character correlation and character variation within populations. Through simulations, we demonstrate that ignoring the population variation (or population “noise”) and the correlation among characters leads to biased estimates of...

Data from: Interactions between plant genome size, nutrients and herbivory by rabbits, molluscs and insects on a temperate grassland

Maïté S. Guignard, Michael J. Crawley, Dasha Kovalenko, Richard A. Nichols, Mark Trimmer, Andrew R. Leitch & Ilia J. Leitch
Angiosperm genome sizes (GS) vary c. 2,400-fold. Recent research has shown that GS influences plant abundance, and plant competition. There are also tantalising reports that herbivores may select plants as food dependent on their GS. To test the hypothesis that GS plays a role in shaping plant communities under herbivore pressure, we exploit a grassland experiment that has experimentally excluded herbivores and applied nutrient over 8 years. Using phylogenetically-informed statistical models and path analyses, we...

Data from: Multiscale patterns of rarity in fungi, inferred from fruiting records

Alan C. Gange, Lewis P. Allen, Aline Nussbaumer, Edward G. Gange, Carrie Andrew, Simon Egli, Beatrice Senn-Irlet & Lynne Boddy
Aim: It is unknown whether fungi show similar trends to other organisms in their macroecological patterns of abundance and spatial distribution. Here, we investigated fungal abundance-occupancy relationships to determine whether fungi that are common at a local scale tend to be more widely distributed. Location: UK and Switzerland Time period: 1950 - 2014 Major taxa studied: Fungi Methods: We used a local dataset of fruiting records of 2,319 species in the UK, accumulated over 65...
