We qualitatively and quantitatively compared the histological anatomy of five aphid species (Paracletus cimiciformis, Forda marginata, Forda formicaria, Baizongia pistaciae and Geoica wertheimae) that induce galls in Pistacia terebinthus shrubs growing in Israel. We also quantitatively compared these galls to those that they create on the same host in Spain. Histological study was conducted following methods described before by the authors. Quantitative differences among the galls were found in five of 12 common anatomical traits: gall thickness, stomatal number in the epidermis-air, size of vascular bundles, distance of phloem ducts from the lumen and number of intraphloematic schizogenous ducts. Other structures were particular to one or some species: number of cracks in the epidermis-lumen, a sclereid layer, trichomes and microcrystal inclusions. Fisher's tests of combined prob...

To verify this hypothesis we used transects to quantified ants in a small sacred forest in a hot Mediterranean region, and the impact of cattle presence in part of it. We hypothesized that it should be mainly inhabited by species having a northern temperate distribution. We detected ants belonging to 39 species including 15 new species for the region. As expected, the majority of them had Palearctic distribution, while others were endemic to the Levant. All of them were known to live in regions with temperate climate. The presence of cattle did not statistically impact on either the number of species or on their biodiversity indices: the average number of ant species per transect was 21 ± 4.6 (SD) in the presence of cows and 23 ± 4.8 in their absence. As hypothesized, the main impact of cattle was on community composition: in the presence of cattle more species were specialists for, or tolerant to, disturbed habitats, resulting in a relatively low Jaccard coefficient of similarity between the two parts of the forest (Sj = 0.56). In conclusion, this small sacred forest, protected for centuries, facilitates the conservation of a great number of shade-loving ant species in a hot region by providing suitable habitats, but the presence of livestock reduces the conservation value of the forest by promoting ant species tolerant to disturbed habitats.

I tested this hypothesis in northern hills of Israel, surveying ant nesting in three habitats: Mediterranean shrub steppe (bata), artificial planted pine stands and unmanaged firebreak bands in pine stands, newly covered with natural bata plants. For this purpose I surveyed twice five sites in the Northern region of Israel for a total of 75 quadrats, each 80-meter square. I detected ant nests in each quadrat by digging soil at 5 cm deep, turning up stones and splitting stumps of hewn trees. I found 102 nests belonging to 19 ant species representing 8% of total ant species living in Israel. Ant species showed high specialization for one of the habitats: twelve species were found in only one habitat, two species in two of them and only five species in three. The Shannon Biodiversity Index was not different in each habitat; however, I found higher similari...
