Data from: Genome-wide variation in nucleotides and retrotransposons in alpine populations of Arabis alpina (Brassicaceae)Aude Rogivue, Rimjhim Roy Choudhury, Stefan Zoller, Stéphane Joost, Francois Felber, Michel Kasser, Christian Parisod & Felix Gugerli
Advances in high-throughput sequencing have promoted the collection of reference genomes and genome-wide diversity. However, the assessment of genomic variation among populations has hitherto mainly been surveyed through single-nucleotide polymorphisms (SNPs) and largely ignored the often major fraction of genomes represented by transposable elements (TEs). Despite accumulating evidence supporting the evolutionary significance of TEs, comprehensive surveys remain scarce. Here, we sequenced the full genomes of 304 individuals of Arabis alpina sampled from four nearby natural...
Data from: Climate‐driven shifts in the distribution of koala browse species from the Last Interglacial to the near futureFarzin Shabani, Mohsen Ahmadi, Katharina J. Peters, Simon Haberle, Antoine Champreux, Frédérik Saltré & Corey J. A. Bradshaw
The koala's (Phascolarctos cinereus) distribution is currently restricted to eastern and south‐eastern Australia. However, fossil records dating from 70 ± 4 ka (ka = 103 years) from south‐western Australia and the Nullarbor Plain are evidence of subpopulation extinctions in the southwest at least after the Last Interglacial (128‐116 ka). We hypothesize that koala sub‐population extinctions resulted from the eastward retraction of the koala's main browse species in response to unsuitable climatic conditions. We further posit...
To understand and forecast biological responses to climate change, scientists frequently use field experiments that alter temperature and precipitation. Climate manipulations can manifest in complex ways, however, challenging interpretations of biological responses. We reviewed publications to compile a database of daily plot‐scale climate data from 15 active‐warming experiments. We find that the common practices of analysing treatments as mean or categorical changes (e.g. warmed vs. unwarmed) masks important variation in treatment effects over space and...
Quantitative constraints on soil organic matter (SOM) dynamics are essential for comprehensive understanding of the terrestrial carbon cycle. Deep soil carbon is of particular interest, as it represents large stocks and its turnover times remain highly uncertain. In this study, SOM dynamics in both the top and deep soil across a climatic (average temperature ~1-9 °C) gradient are determined using time-series (~20 years) 14C data from bulk soil and water-extractable organic carbon (WEOC). Analytical measurements...
Data from: Effects of stand age, richness and density on productivity in subtropical forests in ChinaShuai Ouyang, Wenhua Xiang, Xiangping Wang, Wen-Fa Xiao, Liang Chen, Shenggong Li, Han Sun, Xiangwen Deng, David Forrester, Lixiong Zeng, Pifeng Lei, Xiangdong Lei, Mengmeng Gou & Changhui Peng
1. Forest productivity may be determined not only by biodiversity but also by environmental factors and stand structure attributes. However, the relative importance of these factors in determining productivity is still controversial for subtropical forests. 2. Based on a large dataset from 600 permanent forest inventory plots across subtropical China, we examined the relationship between biodiversity and forest productivity and tested whether stand structural attributes (stand density in terms of trees per ha, age and...
Data from: Increasing plant diversity of experimental grasslands alters the age and growth of Plantago lanceolata from younger and faster to older and slowerAnna Roeder, Fritz H. Schweingruber, Markus Fischer & Christiane Roscher
The persistence of plant populations depends on the ability of individuals to cope with the conditions provided by the community. So far, it is not known whether differences in the diversity and composition of plant communities affect the age structure of plant populations or the expression of stem anatomical traits reflecting investment into plant growth and storage. We analyzed annual growth rings in the secondary xylem and measured stem anatomical traits in individuals from 18...
Climate drives community-wide divergence within species over a limited spatial scale: evidence from an oceanic islandAntonia Salces-Castellano, Jairo Patiño, Nadir Alvarez, Carmelo Andújar, Paula Arribas, Juan J. Braojos-Ruiz, Marcelino Del Arco-Aguilar, Víctor García-Olivares, Dirk Karger, Heriberto López, Ioanna Manolopoulou, Pedro Oromí, Antonio J. Pérez-Delgado, William W. Peterman, Kenneth F. Rijsdijk & Brent C. Emerson
Geographic isolation substantially contributes to species endemism on oceanic islands when speciation involves the colonisation of a new island. However, less is understood about the drivers of speciation within islands. What is lacking is a general understanding of the geographic scale of gene flow limitation within islands, and thus the geographic scale and drivers of geographical speciation within insular contexts. Using a community of beetle species, we show that when dispersal ability and climate tolerance...
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...
Data from: Testing species assemblage predictions from stacked and joint species distribution modelsDamaris Zurell, Niklaus E. Zimmermann, Helge Gross, Andri Baltensweiler, Thomas Sattler & Rafael O. Wüest
Aim: Predicting the spatial distribution of species assemblages remains an important challenge in biogeography. Recently, it has been proposed to extend correlative species distribution models (SDMs) by taking into account (a) covariance between species occurrences in so-called joint species distribution models (JSDMs) and (b) ecological assembly rules within the SESAM (spatially explicit species assemblage modelling) framework. Yet, little guidance exists on how these approaches could be combined. We, thus, aim to compare the accuracy of...
1. Understanding what determines the high elevation limits of trees is crucial for predicting how treelines may shift in response to climate change. Treeline formation is commonly explained by a low-temperature restriction of meristematic activity (sink limitation) rather than carbon assimilation (source limitation). In arid mountains, however, trees face simultaneously low temperature and drought, both potentially restricting their growth and thus setting range limits. However, the mechanisms of treeline formation in high arid mountains are...
Data from: Adaptation to local climate in a multi-trait space: evidence from silver fir (Abies alba Mill.) populations across a heterogeneous environmentKatalin Csilléry, Otso Ovaskainen, Christoph Sperisen, Nina Buchmann, Alex Widmer & Felix Gugerli
Heterogeneous environments, such as mountainous landscapes, create spatially varying selection pressure that potentially affects several traits simultaneously across different life stages, yet little is known about the general patterns and drivers of adaptation in such complex settings. We studied silver fir (Abies alba Mill.) populations across Switzerland and characterized their mountainous landscape using downscaled historical climate data. We sampled 387 trees from 19 populations and genotyped them at 374 single-nucleotide polymorphisms (SNPs) to estimate their...
Removal of host plants is a 'tool' that can be used for the eradication of invasive alien plant pests. We developed a spatially explicit agent-based population model to simulate the population dynamics of the European strain of gypsy moth, Lymantria dispar, based on Robinet et al. (2008 - Journal of Animal Ecology 77, 966–973. doi:10.1111/j.1365-2656.2008.01417.x). The model was coded in the R language (R Core Team, 2017) and is deposited in this Dryad record. A...
