Data from: Using seedling and pericarp tissues to determine maternal parentage of dispersed valley oak recruitsPeter E. Smouse, Victoria L. Sork, Douglas G. Scofield & Delphine Grivet
The spatial pattern of established seedlings yields valuable information about variation in fecundity, dispersal, and spatial structure of distributed recruits, but separating maternal and paternal contributions in monoecious species has been hampered by the “2 parent” problem. It is now possible to determine the maternal parentage of established recruits with genetic assay of maternally derived tissues of the seed or fruit, but the DNA of weathered maternal tissues often yields unreliable genotypes, reducing the practical...
Data from: Morphological and moisture availability controls of the leaf area-to-sapwood area ratio: analysis of measurements on Australian treesHenrique Furstenau Togashi, Ian Colin Prentice, Bradley John Evans, David Ian Forrester, Paul Drake, Paul Feikema, Kim Brooksbank, Derek Eamus, Daniel Taylor & Iain Colin Prentice
1. The leaf area-to-sapwood area ratio (LA:SA) is a key plant trait that links photosynthesis to transpiration. The pipe model theory states that the sapwood cross-sectional area of a stem or branch at any point should scale isometrically with the area of leaves distal to that point. Optimization theory further suggests that LA:SA should decrease toward drier climates. Although acclimation of LA:SA to climate has been reported within species, much less is known about the...

Domesticated species are impacted in unintended ways during domestication and breeding. Changes in the nature and intensity of selection impart genetic drift, reduce diversity, and increase the frequency of deleterious alleles. Such outcomes constrain our ability to expand the cultivation of crops into environments that differ from those under which domestication occurred. We address this need in chickpea, an important pulse legume, by harnessing the diversity of wild crop relatives. We document an extreme domestication-related...
Data from: Genomic comparisons reveal biogeographic and anthropogenic impacts in the koala (Phascolarctos cinereus); a dietary-specialist species distributed across heterogeneous environmentsShannon R. Kjeldsen, Herman W. Raadsma, Kellie A. Leigh, Jennifer R. Tobey, David Phalen, Andrew Krockenberger, William A. Ellis, Emily Hynes, Damien P. Higgins & Kyall R. Zenger
The Australian koala is an iconic marsupial with specific dietary requirements distributed across heterogeneous environments, over a large geographic range. The distribution and genetic structure of koala populations has been heavily influenced by human actions, specifically habitat modification, hunting and translocation of koalas. There is currently limited information on population diversity and gene-flow at a species-wide scale, or with consideration to the potential impacts of local adaptation. Using species-wide sampling across heterogeneous environments, and high-density...
Data from: First insights into the transcriptome and development of new genomic tools of a widespread circum-Mediterranean tree species, Pinus halepensis Mill.Sara Pinosio, Santiago C. González-Martínez, Francesca Bagnoli, Federica Cattonaro, Delphine Grivet, Fabio Marroni, Zaida Lorenzo, Juli G. Pausas, Miguel Verdú & Giovanni G. Vendramin
Pinus halepensis is a relevant conifer species for studying adaptive responses to drought and fire regimes in the Mediterranean region. Deciphering the molecular basis of Aleppo pine to the Mediterranean environment is therefore needed. In this study we performed Illumina next-generation sequencing of two phenotypically divergent Pinus halepensis accessions with the aims of i) characterizing the transcriptome through Illumina RNA-Seq of two accessions, phenotypically divergent for adaptive traits link to fire adaptation and drought, ii)...
Data from: Crop pests and predators exhibit inconsistent responses to surrounding landscape compositionDaniel S. Karp, Rebecca Chaplin-Kramer, Timothy D. Meehan, Emily A.

Angelella, Muhammad Zubair Anjum … & Yi Zou
The idea that noncrop habitat enhances pest control and represents a win–win opportunity to conserve biodiversity and bolster yields has emerged as an agroecological paradigm. However, while noncrop habitat in landscapes surrounding farms sometimes benefits pest predators, natural enemy responses remain heterogeneous across studies and effects on pests are inconclusive. The observed heterogeneity in species responses to noncrop habitat may be biological in origin or could result from variation in how habitat and biocontrol are...
