On the occurrence of the Medicinal Leech,Hirudo medicinalis L., in the Levant

Abstract

Historical records of H. medicinalis are reviewed and specimens have been identified from recent collections of leeches in northern Israel, confirming that this species has not disappeared from our area.     

Recurrent origin of peripheral,coastal (sub)species in Mediterranean Senecio (Asteraceae)

Background: It is argued that coastal endemic taxa may evolve in parallel at the periphery of the distributional range of a widespread species.

Aims: We tested this hypothesis for the origins of three peripheral, coastal isolates of Senecio, S. glaucus ssp. glaucus (Israel), S. g. ssp. coronopifolius p.p. (Sicily), and S. hesperidium (Morocco), from widespread S. glaucus ssp. coronopifolius. We also determined the relative roles of selection vs. genetic drift in shaping phenotypic divergence in ssp. glaucus and S. hesperidium, using Lande’s test of neutral morphological change.

Methods: We surveyed morphological and/or allozyme variation in the three peripheral isolates and mainly inland populations of S. g. ssp. coronopifolius.

Results: Genetic data supported independent origins of the coastal taxa from nearby populations of ssp. coronopifolius. These descendant and ancestral populations showed pronounced morphological but weak genetic differentiation. Phenotypic similarities between ssp. glaucus (Israel) and S. hesperidium (Morocco) in plant height and floral traits may have resulted from parallel divergent selection from ssp. coronopifolius, though drift remains an alternative cause in S. hesperidium.

Conclusions: Our results indicate parallel ecotype formation and (sub)speciation in Senecio in which primarily selective vs. neutral determinants promoted the recurrent origin of coastal types in, respectively, Israel and Morocco.

The presented contribution concerns the study of several samples of Microcoryphia and of Zygentoma obtained in Israel; an up to date of the species of these insect Orders reported from Palestine is also presented. Genus Hyperlepisma (Lepismatidae: Ctenolepismatinae) is reported for the first time from the country and one new species H. palaestinensis n. sp., is described from the northern Negev. Another new species this one of the genus Lepidospora s. s. (Nicoletiidae: Coletiniinae), L. (L.) ayyalonica n. sp., is described from the Ayyalon Cave in Western Central Israel, from where several other terrestrial and aquatic endemic arthropods were already known.     

Review of subtribe Pterellina Rohdendorf, 1967 (Diptera: Sarcophagidae) of Middle East with descriptions of twelve new species

Summary

Based on a revision of large recent collections housed at the Natural History Museum (London), Tel Aviv University and in the private collection of Yu. Verves and L. Khrokalo (Kyiv, Ukraine), new distributional data and an updated list with comments of 28 species of Middle Eastern Sarcophagidae of the subtribe Pterellina are presented. Seventeen of them are recorded for Israel, 11 for Egypt, four for Iran, two each for the Palestinian Authority, Saudi Arabia and Turkey, and one each for Jordan and the UAE. No data are known for the territories of Bahrain, Cyprus, Iraq, Kuwait, Lebanon, Oman, Qatar, Syria and Yemen. Twelve species new to science are described, including nine from Israel (Chaetapodacra montana n. sp., Eremasiomyia bicolor n. sp., E. deserta n. sp., E. fuscata n. sp., Protomiltogramma bidentata n. sp., P. serrata n. sp., Pterella hermonica n. sp., P. indigens n. sp., P. zefatica n. sp.), two from Egypt (Chaetapodacra griseola n. sp., Eremasiomyia alba n. sp.) and one from Saudi Arabia (Protomiltogramma arabica n. sp.). The male of Eremasiomyia nigra Rohdendorf, 1935 is described for the first time. One new combination of specific name is proposed ? Protomiltogramma immunita (Villeneuve, 1923), n. comb. Original keys for the identification of genera and species are proposed. An annotated list of all world genera and species and compiled data on larval habits of Pterellina are included.     

Diversity and ecology of algae from the Nahal Qishon river,northern Israel

In 59 samples of periphyton and phytoplankton collected in 2002 - 2003 from the Nahal Qishon (Qishon River), northern Israel, we found 178 species from seven divisions of algae and cyanoprocaryotes. Diatoms, clorophytes, and cyanoprocaryotes prevail. Nitzschia and Navicula (Bacillariophyta) are the most abundant. Most of the species are cosmopolitan or widespread, except Lagynion janei (Chrysophyta), which is endemic for the Mediterranean Realm. About 17% of species (26) are new for Israel and five of them represent the first recorded genera: Crinalium endophyticum Crow, Actinocyclus normanii (Gregory) Hustedt, Rhizoclonium hieroglyphicum (Agardh) Kütz (Chlorophyta), Lagynion janei Bourelly, and Stylococcus aureus Chodat. Most of them come from a rare riverine assemblage with red alga Audouinella pygmea, as well as from the estuarine assemblage. Alkaliphiles predominate among the indicators of acidity, with few acidophiles confined to the communities under the impact of industrial wastes. Among the indicators of salinity, most numerous are the oligohalobien-indifferents and species adapted to a moderate salinity level. The relative species richness of ecological groups and the indices of saprobity are correlated with changes in conductivity, pH, and N-nitrate concentration. Indicators of organic pollution fall in the range of betameso- to alfamesosaprobic self-purification grades. Our studies show ecological significance of the Nahal Qishon as a model for a strongly disturbed aquatic ecosystem in the coastal zone of eastern Mediterranean.     

Diversity and ecology of algae from the Lower Jordan River,Israel

Abstract

The Lower Jordan River stretches from the outlet of Lake Kinneret till the Dead Sea and is one of the most polluted rivers in Israel. In order to estimate the aquatic ecosystem of the northern part of the Lower Jordan River we used algal communities as biological indicators in the rainy and dry seasons of 2005 and 2007. We found 152 species of algae and cyanoprokaryotes from seven taxonomic divisions, which were mostly dominated by diatoms accompanied by the greens, blue‐greens and euglenoids. The xanthophycean species Heterococcus viridis, a red freshwater alga Audouinella hermannii, and a cyanobacterium Microcrocis marina were found for the first time in Israel. In the ecological analysis we revealed groups of freshwater algae according to pH, salinity, and saprobity as well as temperature, streaming and oxygenation. Quantitative information on the relationship between species and environmental variables was obtained using CCA analysis, emphasizing the major seasonal parameters. The extent of association of species with the environmental variables vector allowed us to determine the bio‐sensors and bio‐indicators, which may be relevant for monitoring of pollutants in the Lower Jordan River. The combination of bio‐indicational methods and statistics were effective in the determination of the main factors influencing algal diversity, as well as in revealing the indicators or bio‐sensing species for the most important environmental variables.

Furthermore, these three species are reported for the first time in association with Quercus calliprinos. Macro- and microscopical characteristics, distribution, ecology, and illustrations related to morphology and anatomy of the species are provided.     

Groundnut pod rot potential in three crop rotations,as indicated by the relative pythium population in soil

Summary The severity of a groundnut (Arachis hypogaea L.) pod rot caused byPythium spp. was found to depend on crop rotation. In order to evaluate Pythium in the soil, baits ofSorghum vulgare Pers. kernels soaked with Pimaricin were used. Most baited Oomycetes were identified asPythium spp. The relative population density of Oomycetes in the soil, one year before the final groundnut harvest, was indicative of pod rot incidence at that harvest.

Diet of the nominate Southern Grey Shrike Lanius meridionalis meridionalis in the north of its range (Mediterranean France)

Capsule In this region the diet is mainly cold-blooded prey, mostly insects such as beetles.

Aims To describe the diet of this newly separated, poorly documented and endangered species.

Method Diet was inferred from pellet analysis, collected during a single breeding and winter period in the steppe of the Crau.

Results A total of 5409 prey were identified from 257 pellets. Vertebrates were seldom taken, except by adults (small passerines) during the fledgling period. High seasonal differences were found. Hymenoptera were largely consumed in autumn, Arachnida in autumn and winter, Orthoptera in summer and autumn and Lepidoptera larvae in winter and spring and by fledglings. Nevertheless, Coleoptera were ingested in large proportions all year round. Carabidae were the main prey in winter and Melolonthidae were especially important for adults during the nestling period, as were Cetoniidae for the fledglings.

Conclusion Small mammals and small birds were less exploited in France and Spain (L. m. meridionalis) than in Israel (L. m. elegans or L. m. aucheri), whereas the opposite might be expected, following a north–south climatic gradient. Thus, the nominate subspecies L. m. meridionalis differed in diet from L. m. elegans or L. m. aucheri.     

White folks: race and identity in rural America

Abstract

Since the breakdown of the Middle East Peace Summit at Camp David in 2000 and the start of the second Palestinian Intifada there has been a voluminous literature that asserts that hostility to Israel and Zionism is a new form of anti-Semitism. This essay critiques the ‘new anti-Semitism’ view. Reversing the method that Plato uses in the Republic, the analysis moves from microcosm (an imaginary ride on a London bus) to macrocosm (the Middle East). In the process, the author argues that anti-Semitism is best defined not by an attitude to Jews but by the figure of ‘the Jew’. In the light of the analysis, and bearing in mind the variety of possible reasons for hostility to Israel or Zionism, it is difficult to see how the ‘new anti-Semitism’ view can be sustained.     

The importance of micro-habitat in the breeding of Barn Owls Tyto alba

Capsule?Habitat parameters associated with 706 Barn Owl (Tyto alba) nesting boxes in Israel were analysed. Pairs bred in 259 of the boxes. The intensity of agricultural practices at nestbox sites were shown to have only a weak effect on aspects of Barn Owl breeding in this region.

Representation,minorities and electoral reform: the case of the Palestinian minority in Israel

ABSTRACT

The article examines the impact of the recent change in the electoral threshold in Israel, from 2 per cent to 3.25 per cent, on the political representation of the Palestinian minority in Israel in the 2015 national election. I argue that the change in the threshold had a direct impact on Palestinian electoral representation and that this change provided incentives to Palestinian leadership to broaden their appeal and become more inclusive in their agenda. Following recent scholarship on ethnic minorities and employing the concept of “representational claims”, I suggest that through the provision of electoral incentives, institutional design can influence not only the degree of representation, but its substantive claims as well.     

Phylogeny and systematics of the Acrapex apicestriata (Bethune-Baker, 1911) species complex (Lepidoptera,Noctuidae, Noctuinae,Apameini, Sesamiina) with the description of eight new species from the Afrotropics

Twelve morphologically similar species of Acrapex Hampson 1894, (Lepidoptera, Noctuidae, Noctuinae, Apameini, Sesamiina), from Western, Central and Eastern Africa are reviewed. Eight of these species are new to science and are described: Acrapex akunamatata n. sp. and A. incrassata n. sp. from Kenya; A. gracilis n. sp., A. iringa n. sp., A. lukumbura n. sp. and A. rungwe n. sp. from Tanzania; A. soyema n. sp. from Ethiopia; and A. zoutoi n. sp. from Benin. All 12 species belong to a species complex that we hereby define as the Acrapex apicestriata group. Host-plants for three of the new species are recorded: Setaria incrassata (Hochst.) Hack. for Acrapex incrassata; Cymbopogon pospishilii (K. Schum.) C.E. Hubb. for A. rungwe; and Andropogon perligulatus Stapf. for A. zoutoi. We also conducted molecular phylogenetic analyses (using maximum likelihood and Bayesian inference) on a six gene multimarker molecular dataset (four mitochondrial and two nuclear gene fragments; 4581 nucleotides in length) consisting of 15 Acrapex species (including seven species from the apicestriata group) and four outgroups species from the subtribe Sesamiina (from genera Busseola Thurau 1904, Sciomesa Tams & Bowden 1953, Pirateolea Moyal, Le Ru, Conlong, Cugala, Defabachew, Matama-Kauma, Pallangyo & Van den Berg 2010 and Sesamia Boisduval & Guenée 1852). Both maximum likelihood and Bayesian inference analyses yield a similar and well-supported topology, which supports the monophyly of the apicestriata group.     

RAPD polymorphism of wild emmer wheat populations, Triticum dicoccoides, in Israel

 Genetic diversity in random amplified polymorphic DNAs (RAPDs) was studied in 110 genotypes of the tetraploid wild progenitor of wheat, Triticum dicoccoides, from 11 populations sampled in Israel and Turkey. Our results show high level of diversity of RAPD markers in wild wheat populations in Israel. The ten primers used in this study amplified 59 scorable RAPD loci of which 48 (81.4%) were polymorphic and 11 monomorphic. RAPD analysis was found to be highly effective in distinguishing genotypes of T. dicoccoides originating from diverse ecogeographical sites in Israel and Turkey, with 95.5% of the 100 genotypes correctly classified into sites of origin by discriminant analysis based on RAPD genotyping. However, interpopulation genetic distances showed no association with geographic distance between the population sites of origin, negating a simple isolation by distance model. Spatial autocorrelation of RAPD frequencies suggests that migration is not influential. Our present RAPD results are non-random and in agreement with the previously obtained allozyme patterns, although the genetic diversity values obtained with RAPDs are much higher than the allozyme values. Significant correlates of RAPD markers with various climatic and soil factors suggest that, as in the case of allozymes, natural selection causes adaptive RAPD ecogeographical differentiation. The results obtained suggest that RAPD markers are useful for the estimation of genetic diversity in wild material of T. dicoccoides and the identification of suitable parents for the development of mapping populations for the tagging of agronomically important traits derived from T. dicoccoides.

The new species, close toM. kieferi, is described and some remarks are given for the other species.     

Comparison of the hatching process of the tadpole shrimps Triops cancriformis and Lepidurus apus lubbocki (Notostraca) and its relation to their distribution in rain-pools in Israel

Rain-pool habitats are gradually disappearing in Israel as a result of agricultural and urban development. Present and past records of notostracan distribution here reveal a difference in the occurrence of Triops cancriformis and Lepidurus apus lubbocki, the former rather rare, and support the suggestion that species of Triops are more thermophilic than Lepidurus, with optimal hatching temperature 8–12°C higher. The limited distribution of T. cancriformis in Israel may be partly attributed to sub-optimal temperatures (<20°C) in early winter.All populations of T. cancriformis in Israel were monosexual female. Resting Notostraca eggs float and become exposed to light, needed for hatching, and to warm day-time temperatures at the water surface which enhance embryonic development. Exposure to higher temperatures may be particularly important for the thermophilic T. cancriformis in Israel, where deep water temperatures in early winter are often below hatching values.
