1. Plant functional traits, in particular specific leaf area (SLA), wood density and seed mass, are often good predictors of individual tree growth rates within communities. Individuals and species with high SLA, low wood density and small seeds tend to have faster growth rates. 2. If community-level relationships between traits and growth have general predictive value, then similar relationships should also be observed in analyses that integrate across taxa, biogeographic regions and environments. Such global...
Data from: Speciation by genome duplication: repeated origins and genomic composition of the recently formed allopolyploid species Mimulus peregrinusMario Vallejo-Marin, Richard J. A. Buggs, Arielle M. Cooley & Joshua R. Puzey
Whole genome duplication (polyploidisation) is a mechanism of “instantaneous” species formation that has played a major role in the evolutionary history of plants. Much of what we know about the early evolution of polyploids is based upon studies of a handful of recently formed species. A new polyploid hybrid (allopolyploid) species Mimulus peregrinus, formed within the last 140 years, was recently discovered on the Scottish mainland and corroborated by chromosome counts. Here, using targeted, high-depth...
Data from: Sex differences in the effects of juvenile and adult diet on age-dependent reproductive effortThomas M. Houslay, John Hunt, Matthew C. Tinsley & Luc F. Bussière
Sexual selection should cause sex differences in patterns of resource allocation. When current and future reproductive effort trade-off, variation in resource acquisition might further cause sex differences in age-dependent investment, or in sensitivity to changes in resource availability over time. However, the nature and prevalence of sex differences in age-dependent investment remain unclear. We manipulated resource acquisition at juvenile and adult stages in decorated crickets, Gryllodes sigillatus, and assessed effects on sex-specific allocation to age-dependent...
Data from: Range-wide population genetics and variation in morph ratio in style-dimorphic Narcissus papyraceus (Amaryllidaceae)Violeta I. Simón-Porcar, F. Xavier Picó & Juan Arroyo
Premise of the study: Theoretical models state that natural selection and mating patterns account for floral morph ratio in style- polymorphic plants. However, the demographic history of populations can also influence variation in morph ratios. If so, we hypothesize an association between the morph ratios and the genetic structure across populations. Methods: We used nuclear microsatellites to assess genetic variation and structure in populations of Narcissus papyraceus, a style-dimorphic plant whose floral morph ratios (L-morph...
Data from: Sex allocation theory reveals a hidden cost of neonicotinoid exposure in a parasitoid waspPenelope R. Whitehorn, Nicola Cook, Charlotte V. Blackburn, Sophie M. Gill, Jade Green, Shuker M. David & D. M. Shuker
Sex allocation theory has proved to be one the most successful theories in evolutionary ecology. However, its role in more applied aspects of ecology has been limited. Here we show how sex allocation theory helps uncover an otherwise hidden cost of neonicotinoid exposure in the parasitoid wasp Nasonia vitripennis. Female N. vitripennis allocate the sex of their offspring in line with Local Mate Competition (LMC) theory. Neonicotinoids are an economically important class of insecticides, but...
Data from: Climatic stress during stand development alters the sign and magnitude of age-related growth responses in a subtropical mountain pinePaloma Ruiz-Benito, Jaime Madrigal-Gonzalez, Sarah Young, Pierre Merctoris, Liam Cavin, Tsurng-Juhn Huang, Jan-Chan Chen, Alistair S. Jump, Pierre Mercatoris & Jan-Chang Chen
The modification of typical age-related growth by environmental changes is poorly understood, In part because there is a lack of consensus at individual tree level regarding age-dependent growth responses to climate warming as stands develop. To increase our current understanding about how multiple drivers of environmental change can modify growth responses as trees age we used tree ring data of a mountain subtropical pine species along an altitudinal gradient covering more than 2,200 m of...
Data from: Fuels and fires influence vegetation via above- and below-ground pathways in a high-diversity plant communityPaul R. Gagnon, Heather A. Passmore, Matthew Slocum, Jonathan A. Myers, Kyle E. Harms, William J. Platt & C. E. Timothy Paine
1. Fire strongly influences plant populations and communities around the world, making it an important agent of plant evolution. Fire influences vegetation through multiple pathways, both above- and belowground. Few studies have yet attempted to tie these pathways together in a mechanistic way through soil heating even though the importance of soil heating for plants in fire-prone ecosystems is increasingly recognized. 2. Here we combine an experimental approach with structural equation modelling (SEM) to simultaneously...
Data from: Unravelling the evolutionary history and future prospects of endemic species restricted to former glacial refugiaOrly Razgour, Irene Salicini, Carlos Ibáñez, Ettore Randi & Javier Juste
The contemporary distribution and genetic composition of biodiversity bear a signature of species’ evolutionary histories and the effects of past climatic oscillations. For many European species, the Mediterranean peninsulas of Iberia, Italy and the Balkans acted as glacial refugia and the source of range recolonization, and as a result, they contain disproportionately high levels of diversity. As these areas are particularly threatened by future climate change, it is important to understand how past climatic changes...
