Data from: Interannual variations in needle and sapwood traits of Pinus edulis branches under an experimental drought

Marceau Guerin, Dario Martin-Benito, Georg Von Arx, Laia Andreu Hayles, Kevin L. Griffin, Rayann Hamdan, Nate G. McDowell, Robert Muscarella, Will Pockman, Pierre Gentine, William Pockman & Laia Andreu-Hayles
1) In the Southwest United States, recent large-scale die-offs of conifers raise the question of their resilience and mortality under droughts. To date, little is known about the interannual structural response to droughts. 2) We hypothesized that piñon pines (Pinus edulis) respond to drought by reducing the drop of leaf water potential in branches from year to year through needle morphological adjustments. We tested our hypothesis using a seven-year experiment in central New Mexico with...

Data from: In situ genetic association for serotiny, a fire-related trait, in Mediterranean maritime pine (Pinus pinaster Aiton)

Katharina B. Budde, Myriam Heuertz, Ana Hernández-Serrano, Juli G. Pausas, Giovanni G. Vendramin, Miguel Verdú & Santiago C. González-Martínez
Wildfire is a major ecological driver of plant evolution. Understanding the genetic basis of plant adaptation to wildfire is crucial, because impending climate change will involve fire regime changes worldwide. We studied the molecular genetic basis of serotiny, a fire-related trait, in Mediterranean maritime pine using association genetics. A single nucleotide polymorphism (SNP) set was used to identify genotype : phenotype associations in situ in an unstructured natural population of maritime pine (eastern Iberian Peninsula)...

Data from: Congruent phylogeographic patterns of eight tree species in Atlantic Central Africa provide insights on the past dynamics of forest cover

Gilles Dauby, Jérôme Duminil, Myriam Heuertz, K. Guillaume Koffi, Tariq Stévart & Olivier J. Hardy
Cycles of Quaternary climate change are assumed to be major drivers of African rainforest dynamics and evolution. However, most hypotheses on past vegetation dynamics relied on palaeobotanical records, an approach lacking spatial resolution, and on current patterns of species diversity and endemism, an approach confounding history and environmental determinism. In this context, a comparative phylogeographic study of rainforest species represents a complementary approach because Pleistocene climate fluctuations may have left interpretable signatures in the patterns...

Data from: Causes and consequences of large clonal assemblies in a poplar hybrid zone

David Macaya-Sanz, Myriam Heuertz, Dorothea Lindtke, Giovanni G. Vendramin, Christian Lexer & Santiago C. Gonzalez-Martinez
Asexual reproduction is a common and fundamental mode of reproduction in plants. Although persistence in adverse conditions underlies most known cases of clonal dominance, proximal genetic drivers remain unclear, in particular for populations dominated by a few large clones. In this study, we studied a clonal population of the riparian tree Populus alba in the Douro river basin (northwestern Iberian Peninsula) where it hybridizes with Populus tremula, a species that grows in highly contrasted ecological...

Data from: Can facilitation influence the spatial genetics of the beneficiary plant population?

Maria Clara Castellanos, Santiago Donat-Caerols, Santiago C. González-Martínez & Miguel Verdú
Plant facilitation is a positive interaction where a nurse or nurse plant community alters the local conditions, improving the life-time fitness of other beneficiary plants. In stressful environments, a common consequence is the formation of discrete vegetation patches under nurse plants, surrounded by open space. The consequences of such spatial patterns have been studied mostly at the community level. At the population level, facilitation causes a distribution of beneficiary individuals that could have intra-specific genetic...

Data from: Climatic drivers of leaf traits and genetic divergence in the tree Annona crassiflora: a broad spatial survey in the Brazilian savannas

Priciane C. Ribeiro, Matheus L. Souza, Larissa A. C. Muller, Vincenzo A. Ellis, Myriam Heuertz, José P. Lemos-Filho & Maria Bernadete Lovato
The Cerrado is the largest South American savanna and encompasses substantial species diversity and environmental variation. Nevertheless, little is known regarding the influence of the environment on population divergence of Cerrado species. Here, we searched for climatic drivers of genetic (nuclear microsatellites) and leaf trait divergence in Annona crassiflora, a widespread tree in the Cerrado. The sampling encompassed all phytogeographic provinces of the continuous area of the Cerrado and included 397 individuals belonging to 21...

Data from: Severity of impacts of an introduced species corresponds with regional eco-evolutionary experience

Kimberley T. Davis, Ragan M. Callaway, Alex Fajardo, Anibal Pauchard, Martin A Nunez, Rob W Brooker, Bruce D. Maxwell, Romina D Dimarco, Duane A Peltzer, Bill Mason, Seppo Ruotsalainen, Anne C S McIntosh, Robin J Pakeman, Alyssa Laney Smith & Michael Gundale
Invasive plant impacts vary widely across introduced ranges. We tested the hypothesis that differences in the eco-evolutionary experience of native communities with the invader correspond with the impacts of invasive species on native vegetation, with impacts increasing with ecological novelty. We compared plant species richness and composition beneath Pinus contorta to that in adjacent vegetation and other P. contorta stands across a network of sites in its native (Canada and USA) and non-native (Argentina, Chile,...

Data from: Context-dependent colonisation of terrestrial habitat 'islands' by a long-distance migrant bird

Robin C. Whytock, Elisa Fuentes-Montemayor, Kevin Watts, Nicholas A. Macgregor, Lefora Williams & Kirsty J. Park
Landscape context can affect how individuals perceive patch quality during colonisation. However, although context-dependent colonisation has been observed in aquatic environments it has rarely been studied in terrestrial environments or at large spatial scales. Here, we assessed how landscape context influenced colonisation rates in a large-scale (c.7000 km2) terrestrial system where colonisers (Willow Warbler Phylloscopus trochilus) are capable of rapid, long-distance movements. Bioacoustic recorders were used to detect first song dates (an indicator of colonisation...

LeWoS: A universal leaf‐wood classification method to facilitate the 3D modelling of large tropical trees using terrestrial LiDAR

Di Wang, Stéphane Momo Takoudjou & Eric Casella
1. Leaf-wood separation in terrestrial LiDAR data is a prerequisite for non-destructively estimating biophysical forest properties such as standing wood volumes and leaf area distributions. Current methods have not been extensively applied and tested on tropical trees. Moreover, their impacts on the accuracy of subsequent wood volume retrieval were rarely explored. 2. We present LeWoS, a new fully automatic tool to automate the separation of leaf and wood components, based only on geometric information at...

Predicting hedgehog mortality risks on British roads using habitat suitability modelling

Patrick Wright, Frazer Coomber, Fiona Mathews, Sarah Perkins & Chloe Bellamy
Road vehicle collisions are likely to be an important contributory factor in the decline of the European hedgehog (Erinaceus europaeus) in Britain. Here, a collaborative roadkill dataset collected from multiple projects across Britain was used to assess when, where and why hedgehog roadkill are more likely to occur. Seasonal trends were assessed using a Generalized Additive Model (GAM). There were few casualties in winter — the hibernation season for hedgehogs — with a gradual increase...

Translocated native pine martens Martes martes alter short-term space use by invasive non-native grey squirrels Sciurus carolinensis

Catherine M. McNicol, David Bavin, Stuart Bearhop, Mark Ferryman, Robin Gill, Cecily E.D. Goodwin, Jenny Macpherson, Matthew J. Silk & Robbie A. McDonald
1. Predators can shape the distributions and dynamics of their prey through direct and indirect mechanisms. Where prey animals are regarded as pests, the augmentation of predator populations might offer a potential tool in their management. 2. Declines in invasive non-native grey squirrel Sciurus carolinensis populations in Ireland and Scotland have been related to an increase in range and density of native pine marten Martes martes populations. These reductions in grey squirrel abundance have, in...

Genetic conservation literature review

Melissa Minter, David O'Brien, Joan Cottrell, Richard Ennos, Jane Hill & Jeanette Hall
Genetic diversity is important for species persistence and Gene Conservation Units (GCUs) have been implemented for forest trees to protect genetic diversity and evolutionary processes in situ. The Convention on Biological Diversity stipulates the protection of genetic diversity as an Aichi target, and so we explore the potential for GCUs to be implemented more widely. Our global systematic review showed that GCUs are currently implemented primarily for plant species of economic importance (109/158 species studied),...

Data from: Positive effects of liana cutting on seedlings are reduced during El Niño-induced drought

Michael J. O'Brien, Christopher D. Philipson, Glen Reynolds, Dzaeman Dzulkifli, Jake L. Snaddon, Robert Ong & Andy Hector
1. Liana cutting is a management practice currently applied to encourage seedling regeneration and tree growth in some logged tropical forests. However, there is limited empirical evidence of its effects on forest demographic rates in Southeast Asia. 2. We used 22 four-hectare plots in the Sabah Biodiversity Experiment (a reduced impact logging site) enrichment line planted with 16 dipterocarp species to assess the effects of complete liana cutting on tree growth and survival. We compared...
