Three new species of Heliotmpium (Boraginaceae) from the Horn of Afiica region

Heliotropium subspinosum sp. nov., from the coastal and subcoastal zones of Yemen, Oman and Somalia, is described and illustrated. This is a woody species with small leaves, and particularly the only 1–4–flowered inflorescences, the axes of which become subspinescent, are remarkable in the genus. H. laxum sp. nov., a slender shrublet from central Somalia, is described, and H. personatum sp. nov., a shrublet that is widespread and scattered, particularly on gypseous ground, in eastern Ethiopia, most parts of Somalia and in southern Yemen, is described and illustrated.     

Five new species of Triotemnus (Coleoptera, Curculionidae, Scolytinae) from Morocco and Yemen

Fivenew species of the genus Triotemnus from Morocco and Yemen are described. Triotemnus is a new genus of Scolytinae for the Yemen region. External morphology of the new species and all morphologically related species of the genus were studied. While the new species from Morocco are morphologically similar to the known species from the corresponding region, all three newly described species from Yemen, mainly two of them living in Socotra, are morphologically very different from all other known species of the genus. Geographical distribution and the probability of endemicity are discussed.     

Freshwater macrofauna of stagnant waters in Yemen Arab Republic

We inventorize the freshwater macrofauna of 4 different wadis, representing the low and highlands, in Yemen Arab Republic. The fauna comprised 6 molluscan, 21 Coleopteran, 8 Hemipteran, 2 amphibian and one fish species. Of the Coleoptera, 8 species are new records to yemen Arab Republic. The genus Exitianus is recorded for the first time in Yemen Arab Republic. Diversity in the uplands and lowlands was similar, but biomass was much higher in the lowlands than in the highlands.

Low genetic diversity and recovery implications of the vulnerable Bankoualé Palm Livistona carinensis (Arecaceae), from North-eastern Africa and the Southern Arabian Peninsula

The Bankoualé Palm, Livistona carinensis is the only known species of Livistona occurring in Africa and is currently classified as vulnerable (IUCN 2004). This extreme outlier species of the genus is restricted to Yemen, Somalia and Djibouti, where all populations are in rapid decline. In Djibouti the palm is confined to three valley systems within the upland plateau of the Goda Massif. This study used microsatellite markers to investigate the genetic diversity and relationships within the species. At the species level L. carinensis contained very low genetic diversity. Most variation was due to the variation between the samples from Yemen and Somalia compared with those in Djibouti. The Djibouti populations were almost monomorphic across the nine loci tested. Interestingly, and despite the small sample sizes, the individuals from botanic gardens collections of the Yemen and Somalia populations were more genetically diverse than the Djibouti populations. This study indicates that the populations in Yemen and Somalia are highly significant for the conservation of the species genetic diversity. Given the lack of genetic diversity both within and among L. carinensis populations in Djibouti, plants could be cultivated for in-situ population enhancement from any seed that is available from within Djibouti with no significant genetic impacts of provenance mismatch. Clearly the populations from Djibouti, Somalia and Yemen are different genetic provenances raising some issues for the conservation and recovery of L. carinensis.     

New species of Tephrosia (Fabaceae) from Somalia and Yemen

The new species Tephrosia flava , from limestone areas in north-eastern Somalia, and T. mahrana , from wadis in the deserts of south-eastern Yemen, are described and illustrated.     

Two new species of Acacia (Leguminosae–Mimosoideae) from Ethiopia and Yemen

Two new species of Acacia belonging to subgenus Acacia, A. origena from the high lands of N Ethiopia and Yemen and A. prasinata from the Rift Valley in central Ethiopia are described. The external morphology of the latter species is shortly described.     

A new species of Limonium (Plumbaginaceae) from Soqotra (Yemen)

Abstract

Limonium guigliae, from the island of Soqotra (Yemen) is described. This new species, close to L. paulayanum differs from it by its size, flower morphology and ecology.     

First record of the Leatherback Turtle,Dermochelys coriacea,from Jordan

Abstract

The present study provides information on the ecology of four species of land snail which are distributed in the north region of the Republic of Yemen (NY). These are Eurypryxis labiosa, Euryptyxis fragosa, Zebrinops albata and Macroptychia sumarana. In addition, Revoilia bentianum and the slug Laevicaulis alte are recorded for the first time from northern Yemen and from Yemen as a whole respectively.

Additions to the scorpion fauna of Yemen

Abstract

Three scorpion species of the family Buthidae are recorded for the first time: Androctonus crassicauda and Buthotus jayakari from the north region of Yemen, and Apistobuthus pterygocercus from Yemen as a whole, The presence of A. crassicauda in the northern region of Yemen closes a gap in our knowledge of its distribution. The other two species are endemisms of the Arabian peninsula: A. pterygocercus is apparently confined to the Arabian peninsula; B. jayakari is probably restricted to the southern part of the Arabian peninsula.     

Functional anatomy of the egg pore in Callosobruchus maculatus: a trade-off between gas-exchange and protective functions?

Abstract. The chorion of the egg in Callosobruchus maculatus (Coleoptera: Bruchidae) provides protection but also has to allow exchange of respiratory gases. A single opening in the chorion (the egg pore) allows diffusion of gases, and young larvae die if the egg pore is blocked. Comparison of respiration rates using a Gilson respirometer showed an increase in oxygen uptake from the first to the seventh day after the egg was laid; the increase was from 6.8 to 11.2 pl/egg/day in a Brazil strain and from 8.6 to 23.5 pl/egg/day in a Yemen strain. The Yemen strain had double the metabolic rate of Brazil-strain insects in the larvae, which are exposed to seed toxins, but not in the non-feeding adults. It is suggested that the higher metabolic rate in the Yemen larvae is related to their ability to develop in seeds that are toxic to the Brazil strain. The egg pore also differed in size and shape between the two strains. The egg pore was cylindrical in the Brazil strain, but shorter and funnel-shaped with an increased external diameter in the Yemen strain. Calculation showed that the different shape and size of the Yemen egg pore would allow a 2–3-fold increase in gas conductance compared with the Brazil strain, and this increase was consistent with the enhanced oxygen requirement of the Yemen larvae, which was a little over twice that of the Brazil larvae at 7 days. The anatomy of egg pores in Cmaculatus thus seems to represent a trade-off between two functions, allowing adequate gas exchange while maintaining the protective function of the chorion.
