Morphology and load transport behaviour of the seed-harvesting ant Messor barbarus Linnaeus 1767
<p>This Excel file contains two datasets. The first dataset (sheet “Morphometric data”) gives the measure of thorax length, body mass as well as the mass of main body segments of 57 individual workers of the ant species <em>Messor barbarus</em> Linnaeus 1767. The workers originated from a colony collected in Saint-Hippolyte, France (42°80 N, 2°98 E) in October 2013. The second dataset (sheet “Transportation data”) relates to observations aiming at investigating the efficiency of <em>M. barbarus</em> workers when transporting pieces of dry pasta on their foraging trails. The data gives the body mass, the characteristics of the item transported, the transportation method (carry or drag), as well as the time required to travel a distance of 1m for 239 individual workers from five colonies located on the campus of the Universitat Autònoma de Barcelona, Spain (41°30′00N, 2°06′49E). For each ant followed the air temperature at ground level is also indicated.</p>

Seed Morphology in Key Spanish Grapevine Cultivars
<p>Photographs were taken with a camera Nikon D80 of 10,2 megapixels. The seeds were oriented with their chalaza downwards, such as to expose the ribs upwards (ventral orientation) and straight in the middle to provide each seed image a maximum of symmetry. Composed images containing 30 seeds per accession were prepared with Corel Photo Paint</p>
Significance of fruit and seed morphology in current taxonomy of the genus Iberis L. (Brassicaceae) in Turkey
<p>Fruit and seed morphology of 10 taxa belonging to the genus <em>Iberis </em>(Brassicaceae) in Turkey were investigated with stereo microscopy (SM) and scanning electron microscopy (SEM), in order to understand and check their diagnostic significance at generic and spesific level. Fruits and seeds of <em>Iberis </em>species were photographed and examined to evaluate different characteristics including fruit size, shape, color, indumentum, surface ornamentation, style length, sinus width, wing width, septum length, and also seed size, shape, color, surface ornamentation, cell types, anticlinal and periclinal cell wall features. In addition, cluster analysis and principal coordinates analysis (PCoA) were performed to reveal the similarities between the related taxa in terms of seed and fruit morphology. According to fruit morphology, <em>Iberis </em>taxa in Turkey are divided into three main groups particularly by fruit shapes, those are ovate, ovate-obovate and ovate-orbicular. In the present study SM photographs of both immature and mature fruits of relevant species were also provided for the first time. Style length, which is one of the most important features between some <em>Iberis </em>taxa was taken into consideration in the study. There are three types of seed shapes, those are inequilateral obovate, broadly obovate and inequilateral elliptic. The fruit size limits of <em>I. simplex</em> were also been expanded. The UPGMA tree topology of cluster analysis based on a total of 20 fruit and seed characters presents the current taxonomical classification of the taxa in Turkey, which is updated in this study. An identification key for the genus <em>Iberis </em>in Turkey was provided in the light of current data.</p>
