Data from: Genetic evidence for a Janzen-Connell recruitment pattern in reproductive offspring of Pinus halepensis trees.

Ofer Steinitz, David Troupin, Giovanni G Vendramin & Ran Nathan
Effective seed dispersal, combining both dispersal and post-dispersal (establishment) processes, determines population dynamics and colonization ability in plants. According to the Janzen-Connell (JC) model, high mortality near the mother plant shifts the offspring establishment distribution farther away from the mother plant relative to the seed dispersal distribution. Yet, extending this prediction to the distribution of mature (reproductive) offspring remains a challenge for long-living plants. To address this challenge we selected an isolated natural Aleppo pine...

Data from: Effects of forest plantations on the genetic composition of conspecific native Aleppo pine populations

Ofer Steinitz, Juan J. Robledo-Arnuncio & Ran Nathan
Afforestation is a common and widespread management practice throughout the world, yet its implications for the genetic diversity of native populations are still poorly understood. We examined the effect of Aleppo pine (Pinus halepensis) plantations on the genetic composition of nearby conspecific native populations. We focused on two native populations in Israel with different levels of isolation from the surrounding plantations and compared the genetic diversity of naturally established young trees within the native populations...

Data from: Islands and streams: clusters and gene flow in wild barley populations from the Levant

Sariel Hübner, Torsten Günther, Andrew Flavell, Eyal Fridman, Andreas Graner, Abraham Korol & Karl J. Schmid
The domestication of plants frequently results in a high level of genetic differentiation between domesticated plants and their wild progenitors. This process is counteracted by gene flow between wild and domesticated plants because they are usually able to inter-mate and to exchange genes. We investigated the extent of gene flow between wild barley Hordeum spontaneum and cultivated barley Hordeum vulgare, and its effect on population structure in wild barley by analyzing a collection of 896...
