The oligolectic bee genus Melitta Kirby, 1802 (Melittidae: Melittinae) is recorded from the Arabian Peninsula for the first time, and from Saudi Arabia in particular. A series of females of Melitta schmiedeknechti Friese, 1898 were captured near Jabal al Mashār, Ha’il, Saudi Arabia, representing the first occurrence of this species, previously known across northern Africa and the southern Levant. Brief remarks and a key are provided for the two subspecific forms of M. schmiedeknechti. 相似文献

It is now known that several population movements have taken place at different times throughout southern Arabian prehistory. One of the principal questions under debate is if the Early Holocene peopling of southern Arabia was mainly due to input from the Levant during the Pre‐Pottery Neolithic B, to the expansion of an autochthonous population, or some combination of these demographic processes. Since previous genetic studies have not been able to include all parts of southern Arabia, we have helped fill this lacuna by collecting new population datasets from Oman (Dhofar) and Yemen (Al‐Mahra and Bab el‐Mandab). We identified several new haplotypes belonging to haplogroup R2 and generated its whole genome mtDNA tree with age estimates undertaken by different methods. R2, together with other considerably frequent southern Arabian mtDNA haplogroups (R0a, HV1, summing up more than 20% of the South Arabian gene pool) were used to infer the past effective population size through Bayesian skyline plots. These data indicate that the southern Arabian population underwent a large expansion already some 12 ka. A founder analysis of these haplogroups shows that this expansion is largely attributed to demographic input from the Near East. These results support thus the spread of a population coming from the north, but at a significantly earlier date than presently considered by archaeologists. Our data suggest that some of the mtDNA lineages found in southern Arabia have persisted in the region since the end of the Last Ice Age.

Family status was recently proposed for the Tryonicus-Lauraesilpha group (Insecta: Blattodea: Tryonicidae), which had been assigned to Blattidae before. In order to test this hypothesis, a molecular phylogenetic analysis of Blattodea was conducted using the 12S and H3 genes. The results show that Tryonicidae indeed form a lineage distinct from Blattidae. The results are compared to the previous classifications and phylogenetic hypotheses (morphology- and molecular-based). It is suggested that the Polyzosteriinae tribe Methanini should remain in Polyzosteriinae (Blattodea: Blattidae). 相似文献

The Collared Kingfisher (Todiramphus chloris) is widely distributed across the Indian and western Pacific Oceans and consists of about 50 subspecies. Two different subspecies of T. chloris occur in the Arabian Peninsula: T. c. abyssinicus from the Red Sea coast and T. c. kalbaensis from the Arabian Sea coast in the United Arab Emirates and Oman. The aim of this study was to determine the molecular relationship between the two Arabian subspecies and to establish the first DNA barcodes from the Arabian Peninsula for this species. Three different mitochondrial genes were used: (i) cytochrome c oxidase subunit I (COI), (ii) 12S rRNA (12S) and (iii) NADH dehydrogenase-1 (ND1). The COI gene sequences of the two subspecies were 100% identical, while the 12S and ND1 gene sequences revealed a unique single nucleotide variation between the two subspecies. Thus, this single nucleotide variation can be used as a DNA barcode to discriminate between two subspecies. Furthermore, the genetic profile or fingerprint for both subspecies were compared using ten primers of the highly polymorphic nuclear markers (Inter Simple Sequence Repeat, ISSR). As expected, the DNA analysis of the ISSR markers was able to distinguish between the specimens of the two subspecies. These results suggest that T. c. abyssinicus and T. c. kalbaensis are not identical and thus belong to different subspecies. Besides, the sequences of the COI gene for T. c. abyssinicus and T. c. kalbaensis differs by only 1.28% from T. sanctus suggesting that the Arabian subspecies are closely related to the Sacred Kingfisher (T. sanctus). 相似文献

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. 相似文献

This study is to evaluate the potential of endophytic fungi of Salvadora persica for the production of bioactive compounds against pathogenic bacteria and fungi. Forty-two fungal isolates were obtained from 135 young and old stem and 125 root segments. Those 42 isolates representing ten fungi include: Trichoderma sp. (the most common), two species of Alternaria, Rhizopus arrhizus and 6 sterile mycelia. The ten fungi were grown in liquid culture and their crude extracts were tested against pathogenic bacteria and fungi. Nine crude extracts gave positive reactions against pathogenic bacteria of which Alternaria sp. (A8) was chosen further study. The fungal isolate was growing as sterile mycelium and was identified by phylogenetic analyses based on LSU rDNA sequence data and it might represent undescribed species of Alternaria. Sixty-two bioactive chemical compounds were identified from the ethyl acetate crude extracts of Alternaria sp., of which the following were recorded as major compounds in the active sub-fractions. These compounds showed strong antibacterial activity in combination. 相似文献

The ant genus Solenopsis Westwood, 1840 is the largest in Myrmicinae subfamily having almost 200 described species worldwide. They are commonly distributed in the tropics and temperate areas of the world. Some invasive Solenopsis species are very dreadful. We have already reported a fire ant species, Solenopsis saudiensis Sharaf & Aldawood, 2011, identified using traditional morphometric approaches of species identification. Present study was carried out to develop DNA Barcoding to identify Solenopsis saudiensis and to elucidate genetic structure of the various S. saudiensis populations across their distribution range in Riyadh, Saudi Arabia. The comparison of DNA barcodes showed no genetic diversity among six populations and a queen from S. saudiensis analyzed from the Riyadh region. This genetic resemblance probably reflects their adaptation toward a specific habitat, thus constituting a single and strong gene pool. Our comprehensive field survey did not provide any evidence of Solenopsis species except S. saudiensis in the Riyadh region. Solenopsis saudiensis populations were only found around date palm trees indicating their strong association with date palm groves. Moreover, S. saudiensis has 83–86% sequence identity to other Solenopsis spp. from other parts of the world. Interestingly, the highest sequence identity of (86%) was with that of Solenopsis molesta Say, 1836, the thief ant, from the USA. This study provides a working laboratory procedure and a reference library for the identification of Solenopsis saudiensis. 相似文献

Mountain gazelles (Gazella gazella) rank among the most critically endangered mammals on the Arabian Peninsula. Past conservation efforts have been plagued by confusion about the phylogenetic relationship among various ‘phenotypically discernable’ populations, and even the question of species boundaries was far from being certain. This lack of knowledge has had a direct impact on conservation measures, especially ex situ breeding programmes, hampering the assignment of captive stocks to potential conservation units. Here, we provide a phylogenetic framework, based on the analysis of mtDNA sequences (360 bp cytochrome b and 213 bp Control Region) of 126 individuals collected from the wild throughout the Arabian Peninsula and from captive stocks. Our analyses revealed two reciprocally monophyletic genetic lineages within the presumed species Gazella gazella: one ‘northern clade’ on the Golan Heights (Israel/Syrian border) and one genetically diverse larger clade from the rest of the Arabian Peninsula including the Arava Valley (Negev, Israel). Applying the Strict Phylogenetic Species Concept (sensu Mishler & Theriot, 2000) allows assigning species status to these two major clades. 相似文献

Apterous viviparous females of Neoamphorophora ledi (Wahlgren, 1938) living on Rhododendron degronianum Carr. (Ericaceae) on Honshu island, Japan, are redescribed and the hitherto unknown alate viviparous females are here described. Rhododendron degronianum is a new host plant species for this aphid. This species is recorded for aphid fauna of Eastern Palearctic for the first time. Keys to species of Neoamphorophora based on apterous and alate viviparous females are given. A key to aphid genera with swollen siphunculi living on species of Rhododendron worldwide based on apterous viviparous females is also provided. 相似文献
