Cherry Trees

The possible effect of shaker harvest on root damage of 10-year-old cherry trees was studied on a simple tree structure model. The model was composed of elastic trunk and rigid main roots, the ends of which were connected to the surrounding soil via springs and dumping elements. Equations were set up to be able to calculate the relation between shaking height on the trunk and strain in the roots. To get the data for root break and their elongation at different shaking heights on the trunk, laboratory and field experiments were carried out on cherry trees and on their roots. Having evaluated the measured and calculated data it could be concluded that root damage is to be expected even at 3.6% strain and the risk of it increases with increased trunk amplitudes, i.e.with the decrease of shaking heightat smaller stem diameters (i.e. in younger plantation), andif the unbalanced mass of the shaker machine is too large for the given tree size.

Geopolitical Context

The series of drawings, Encounters – ongoing stems from chance meetings on leisurely road trips around the mountains of Lebanon. The drawings act as markers of my conversations with landowners, farmers, and people directly working in the fields. The formal particularities of drawing, and specifically the use of ink washes, allows for an approach that is both intuitive and intentional. This approach reproduces the spontaneity of these accidental or brief exchanges with people who have a vested interest in Lebanese land. Each conversation is represented by a simple tree branch, or a fragment of a (flowering) plant, belonging to the site and moment the encounter took place. This fragment indexes an encounter in which the farmer's story, experience, or relationship to the land and its borders was shared. Excerpts from our exchanges are also hand-written in Arabic on the picture plane. In the directness of the creative process, and the abstraction of the conversations, this project alludes to, and yet blurs, the sectarian divisions upon which the ownership of land is based, as well as a present geopolitical context. What I share is the marking of unplanned encounters through the representations of fragmented personal accounts along specific terrains and borders.

Simple Tree

Horizontal gene transfer (HGT) is often considered to be a source of error in phylogenetic reconstruction, causing individual gene trees within an organismal lineage to be incongruent, obfuscating the ‘true’ evolutionary history. However, when identified as such, HGTs between divergent organismal lineages are useful, phylogenetically informative characters that can provide insight into evolutionary history. Here, we discuss several distinct HGT events involving all three domains of life, illustrating the selective advantages that can be conveyed via HGT, and the utility of HGT in aiding phylogenetic reconstruction and in dating the relative sequence of speciation events. We also discuss the role of HGT from extinct lineages, and its impact on our understanding of the evolution of life on Earth. Organismal phylogeny needs to incorporate reticulations; a simple tree does not provide an accurate depiction of the processes that have shaped life's history.
