By def inition, sepsis refers to a life threatening organ dysfunction due to a dysregulated host response to an infection[1]. More precisely, sepsis triggers a multifaceted response characterized by a simultaneous manifestation of proinflammatory and anti-inflammatory elements that disrupt mechanisms intended to maintain homeostasis. Initially, an overwhelming hyperinflammatory reaction ensues, resulting in tissue damage and organ dysfunction.

We tested the role of interspecific competition in driving species distribution at multiple spatial scales using two sibl- ing species of Galerida larks （G cristata and G. theklae） in Morocco （sympatry）, Balearic islands （G theklae only） and Israel （G cristata only）. We first investigated regional-scale determinants by contrasting allopatric versus sympatric patterns in five distinct habitat types. We next focused on a single habitat used by both species, the coastal sand dunes. Dune quadrats were established along the Moroccan coast and completed by a quadrat in the nearest distinct landscape habitat. Poisson regressions were used to model Galerida counts together with ecological predictors as concerns the climate, topography, vegetation structure and soil gra- nulometry. At the local scale, both species preferred grey dunes over white sand dunes, and both were negatively affected by the abundance of the congeneric species in the dune. However, we found that G theklae tended to replace G. cristata in more arid sand dunes, even if the transition was not strictly clinal. Instead, the transition occurred when the surrounding landscape changed from coastal wetlands to bathas （grasslands with shrubs）, highlighting the importance of habitat composition at the landscape scale. The fact that G cristata used bathas in allopatry, but not in sympatry, suggested that the competitive environment contri- buted to determine sand dune occupancy. We suggest that landscape-level effects may be pivotal in explaining species distribu- tion not only at the local scale, by affecting the pool of potential immigrants, but also at the regional scale, by contributing to species＇ range limit [Current Zoology 61 （1）： 10-22, 2015].

The export of nutrients from source organs to parts of the body where they are required （e.g. sink organs） is a fundamental biological process. Export of amino acids, one of the most abundant nitrogen species in plant long-distance transport tissues （i.e. xylem and phloem）, is an essential process for the proper distribution of nitrogen in the plant. Phys- iological studies have detected the presence of multiple amino acid export systems in plant cell membranes. Yet, surpris- ingly little is known about the molecular identity of amino acid exporters, partially due to the technical difficulties hampering the identification of exporter proteins. In this short review, we will summarize our current knowledge about amino acid export systems in plants. Several studies have described plant amino acid transporters capable of bi-directional, facilitative transport, reminiscent of activities identified by earlier physiological studies. Moreover, recent expansion in the number of available amino acid transporter sequences have revealed evolutionary relationships between amino acid exporters from other organisms with a number of uncharacterized plant proteins, some of which might also function as amino acid exporters. In addition, genes that may regulate export of amino acids have been discovered. Studies of these putative transporter and regulator proteins may help in understanding the elusive molecular mechanisms of amino acid export in plants.
