Data from: Effect of epistasis and environment on flowering time of barley reveals novel flowering-delaying QTL alleleNazanin Pesaran Afsharyan, Wiebke Sannemann, Jens Léon & Agim Ballvora
Flowering time is a complex trait and has key role in crop yield and adaptation to environmental stressors such as heat and drought. The aim of this study was to better understand interconnected dynamic of epistasis and environment and look for novel regulators. For this purpose we investigated 534 spring barley MAGIC DH lines for flowering time at various environments. Analysis of QTL, epistatic interaction, QTL × environment (Q×E) and epistasis × environment (E×E) interactions...
Understanding population genetic structure is key to developing predictions about species susceptibility to environmental change, such as habitat fragmentation and climate change. It has been theorized that life-history traits may constrain some species in their dispersal and lead to greater signatures of population genetic structure. In this study, we use a quantitative comparative approach to assess if patterns of population genetic structure in bees are driven by three key species-level life-history traits: body size, sociality,...
Testing Finch’s hypothesis: the role of organismal modularity on the escape from actuarial senescenceConnor Bernard, Aldo Compagnoni & Roberto Salguero-Gómez
1. Until recently, senescence was assumed to be a universal phenomenon. Evolutionary theories of senescence predict that no organism may escape the physiological decline that results in an increase in mortality risk and/or decline in fertility with age. However, evidence both in animals and plants has emerged in the last decade defying such predictions. Researchers are currently seeking mechanistic explanations for the observed variation in ageing trajectories. 2. We argue that the historical view on...
Data from: Habitat amount, not patch size and isolation, drives species richness of macro‐moth communities in countryside landscapesThomas Merckx, Murilo Dantas De Miranda & Henrique Miguel Pereira
Aim: Our aim is to test whether species richness patterns are best explained by the effect of the total amount of habitat within the landscape, or instead by a combination of patch size and patch isolation effects. To this end, we jointly contrast the habitat amount hypothesis and countryside biogeography with patch size and isolation concepts from island biogeography. Location: Three multi-habitat landscapes in Peneda-Gerês National Park, NW Portugal. Taxon: Macro-moths (Lepidoptera). Methods: Light-trapping using...
Data from: Release from natural enemies mitigates inbreeding depression in native and invasive Silene latifolia populationsKarin Schrieber, Sabrina Wolf, Catherina Wypior, Diana Höhlig, Stephen R. Keller, Isabell Hensen & Susanne Lachmuth
Inbreeding and enemy infestation are common in plants and can synergistically reduce their performance. This inbreeding × environment (I×E) interaction may be of particular importance for the success of plant invasions if introduced populations experience a release from attack by natural enemies relative to their native conspecifics. Here, we investigate whether inbreeding affects plant infestation damage, whether inbreeding depression in growth and reproduction is mitigated by enemy release and whether this effect is more pronounced...
Data from: Climate outweighs native vs. non-native range-effects for genetics and common garden performance of a cosmopolitan weedChristoph Rosche, Isabell Hensen, Adrian Schaar, Uzma Zehra, Marie Jasieniuk, Ragan M. Callaway, Damase P. Khasa, Mohammad M. Al-Gharaibeh, Ylva Lekberg, David U. Nagy, Robert W. Pal, Miki Okada, Karin Schrieber, Kathryn G. Turner, Susanne Lachmuth, Andrey Erst, Tomonori Tsunoda, Min Sheng, Robin Schmidt, Yanling Peng, Wenbo Luo, Yun Jäschke, Zafar A. Reshi & Manzoor A. Shah
Comparing genetic diversity, genetic differentiation and performance between native and non-native populations has advanced our knowledge of contemporary evolution and its ecological consequences. However, such between-range comparisons can be complicated by high among-population variation within native and non-native ranges. For example, native vs. non-native comparisons between small and non-representative subsets of populations for species with very large distributions have the potential to mislead because they may not sufficiently account for within-range adaptation to climatic conditions,...
Data from: A tale of scale: plot but not neighbourhood tree diversity increases leaf litter ant diversityMichael Staab, Merle Noack, Helge Bruelheide, Werner Härdtle, Goddert Von Oheimb, Thomas Scholten, Steffen Seitz & Carl Skarbek
1. Diversity of producers (e.g. plants) usually increases the diversity of associated organisms, but the scale (i.e. the spatial area of plant diversity considered) at which plant diversity acts on other taxa has rarely been studied. Most evidence for cross-taxon diversity relations come from aboveground consumers that directly interact with plants. 2. Experimental tests of plant diversity effects on elusive organisms inhabiting the leaf litter layer, which are important for nutrient cycling and decomposition, are...
Data from: Neighbour species richness and local structural variability modulate aboveground allocation patterns and crown morphology of individual treesMatthias Kunz, Andreas Fichtner, Werner Härdtle, Pasi Raumonen, Helge Bruelheide & Goddert Von Oheimb
Local neighbourhood interactions are considered a main driver for biodiversity–productivity relationships in forests. Yet, the structural responses of individual trees in species mixtures and their relation to crown complementarity remain poorly understood. Using a large‐scale forest experiment, we studied the impact of local tree species richness and structural variability on above‐ground wood volume allocation patterns and crown morphology. We applied terrestrial laser scanning to capture the three‐dimensional structure of trees and their temporal dynamics. We...
The Island Species-Area relationship (ISAR) describes how the numbers of species increases with increasing size of an island (or island-like habitat, such as lakes), and is one of the oldest laws in ecology. Despite its conceptual importance, there remains a great deal of ambiguity regarding the ISAR and its underlying processes. We compiled data from sampled zooplankton assemblages from several hundred lakes in North America and Europe to examine the influence of the three main...
Data from: A pre-Miocene Irano-Turanian cradle: origin and diversification of the species-rich monocot genus Gagea (Liliaceae)Angela Peterson, Dörte Harpke, Jens Peterson, Alexander Harpke & Lorenzo Peruzzi
The Irano‐Turanian (IT) floristic region is considered an important centre of origin for many taxa. However, there is a lack of studies dealing with typical IT genera that also occur in neighbouring areas. The species-rich monocot genus Gagea Salisb. shows a centre of diversity in IT region and a distribution in adjacent regions, therefore representing a good study object to investigate spatial and temporal relationships among IT region and its neighbouring areas (East-Asia, Euro-Siberia, Himalaya,...
