Determining the age of Qatari Jabal Jassasiyah Petroglyphs
Raid Hassiba,Gerald Benjamin Cieslinski,Brandon Chance,Faisal Abdulla Al-Naimi
QScience Connect , 2012, DOI: 10.5339/connect.2012.4
Abstract: The petroglyph site in Jabal Jassasiyah Qatar is located approximately 60 km northeast of the capital city of Doha and has over 900 different types of petroglyphs. The most commonly found petroglyphs are cupules, which are almost always arranged in geometric patterns. A number of petroglyphs of boats are also found, usually seen from above, with a few seen in profile. As there is little evidence of what age to assign to these petroglyphs, samples of the calcium oxalate containing layers covering the petroglyphs were sent for radiocarbon dating to determine the minimum age they were created. The minimum ages of nine samples taken for analysis were found to be very short, the oldest minimum age being only 235 years BP (before present). No evidence was found for the petroglyphs dating back a few millennia as was previously postulated. Due to the lack of chronological data for Qatar’s archaeological past, the study data cannot completely rule out the petroglyphs dating back to ancient times.

Trabajos de Prehistoria , 1994,
Abstract: This paper highlights the existence of several representations of wild boar primarily on zoomorphic fibulae, in the Western Meseta, which was a Celtic language speaking area. We point out the possible relationship with the European Celtic world, where the boar played an important role and where many boar figurines have been found. Se subraya la existencia de numerosas representaciones de jabalí, mayoritariamente fíbulas zoomorfas, en la Meseta Occidental, territorio en el que se habló una lengua celta. Se apuntan las posibles similitudes con el mundo celta europeo donde el jabalí jugó un papel destacado y cuyas representaciones fueron igualmente abundantes.
Hydrogeochemical Variations of Groundwater of the Northern Jabal Hafit in Eastern Part of Abu Dhabi Emirate, United Arab Emirates (UAE)  [PDF]

Abstract: This study is aimed to assess and evaluate the suitability of groundwater of the area located to the south-east of Al-Ain area in the UAE using hydrogeochemcical approach. The chemical analyses of groundwater samples collected from the study area showed that the groundwater salinity is high which resulted from heavy groundwater pumping. High chloride concentrations in groundwater of Mubazarah and Neima might be attributed to the entrapped saline water within the limestone sequence of Jabal Hafit, or it can be the agricultural activities as it clear from the positive relationship between Cl- and Br-. High sulphate concentrations in groundwater might be related to the presence of gypsum and anhydrite within the limestone sequence of Jabal Hafit. The anionic and cationic compositions of groundwater indicate that the chloride and sodium ions are the dominant and presence of bicarbonate and sulphate may reflect the mixing of such water by the recent freshwater through the existing structural lineaments within the study area. The hydrochemical parameters indicate a relative increase in the concentration of calcium, magnesium and sulphate ions and this could reflect the influence of carbonates and evaporite sediments.
Ecología trófica del jabalí europeo (Sus scrofa) silvestre en Chile Trophic ecology of the wild boar (Sus scrofa) in Chile  [cached]
Revista chilena de historia natural , 2007,
Abstract: Documentamos la dieta del jabalí silvestre en el centro-sur de Chile basados en el examen de 20 estómagos colectados en los faldeos de volcán Mocho-Choshuenco (39°54' S, 72°02' O) y en el Parque Nacional Vicente Pérez Rosales (41°03' S, 71°54' O). La dieta está representada por animales, vegetales y hongos. Entre los vegetales y hongos son consumidas tanto las partes epígeas como hipógeas, lo mismo que frutos y semillas. Hongos y rizomas de Gunnera tinctoria constituyen ítemes vegetales cuantitativamente importantes en la alimentación. El jabalí forrajea en general en ambiente boscoso, pero las especies vegetales más frecuentes en la dieta se encuentran en espacios abiertos o fuera del bosque. El ambiente dominado por Chusquea spp. constituye un importante sitio de alimentación. Los roedores de la familia Muridae dominan entre los animales determinados en la dieta del jabalí. Esta situación, sin embargo, parece obedecer a la ocurrencia de una ratada producto de la semillación masiva de Chusquea spp. durante la época de muestreo. Las aves de la familia Rhinocryptidae e invertebrados (en especial larvas del coleóptero Chiasognathus grantii) constituyen parte frecuente de los ítemes animales de la dieta del jabalí. En comparación a estudios en otras partes del mundo, el jabalí silvestre en Chile consume hongos en porcentaje de ocurrencia similar (65 %) a su dieta en Estados Unidos de América pero bastante más alta que su dieta en Europa (5-32 %). En relación al volumen del componente animal, el jabalí en Chile consume más (16,1 %) que en Estados Unidos de América (6 %) y que en Europa (7-13 %) We document the diet of wild boar in south-central Chile based on analysis of 20 stomachs collected on the outskirts of Mocho-Choshuenco volcano (39°54' S, 72°02' W) and of Vicente Pérez Rosales National Park (41°03' S, 71°54' W). The diet incorporates animals, plants and fungi. Among the latter two, both epigeal and hypogeal parts are consumed, together with fruits and seeds. Fungi and rhizomes of Gunnera tinctoria are the most abundant plant items in the diet. The wild boar in Chile forages chiefly in forested environments, but nonetheless the most frequent plant items in its diet are found in open spaces or outside the forest. Environments dominated by bamboos Chusquea spp. constitute important foraging sites. Rodents in the family Muridae prevail among animal items in the wild boar diet. This situation, however, is associated to the occurrence of a mouse outbreak (ratada) resulting from the mast seeding of Chusquea spp. during our study. Birds in the family Rhino

Abstract: The fungal flora with special attention to Trichoderma in 23 soil samples collected from Al-Jabal Al-Akhdar Region, Libya was studied using different culture media. Trichoderma Selective Medium (TSM), Martin's medium (MT) and Potato Dextrose Agar (PDA) were the superior media for isolating Trichoderma. Martin's medium (MT) and Malt Extract medium (ME) were the most valuable for isolating the greatest number of total fungal count. Trichoderma Selective Medium (TSM) supplemented with 100 μg mL-1 PCNB was the most effective medium for counting Trichoderma and recorded 120-140% efficacy of re-isolation. Trichoderma occurred in moderate frequency in the tested soil and was isolated from 5 soil samples. Trichoderma counted 0.5-1x103 CFU g-1 dry soil and five Trichoderma isolates were identified as Trichoderma harzianum. Aspergillus and Penicillium sp. were the most frequent fungi isolated from the tested soil and were averaged 8.3-5.5 CFU mg-1 soil, respectively. Further studies are needed to clarify the distribution of fungal flora especially Trichoderma sp. in the Libyan soil.

Abstract: The Al Haruj Intra-continental Volcanic Province is the largest part of the extensive volcanic activity in Libya which is considered to be a typical within plate basalts. The volcano-tectonics evolution of this province, as well as its origin, are still widely disputed. According to K-Ar dating previously studied, the volcanic activity started in the Late Miocene and lasted until at least the Late Pleistocene. The field may still be volcanically active. The mafic rocks of Jabal Al Haruj have been classified into six major phases or groups. These phases have been differentiated using Landsat images together with aerial photographs of different scales as well as field observations. The topographic forms of the earliest phase are highly eroded while the forms of the latest phase are usually fresh and very well preserved as regards primary features. Mafic lavas of this field consist of alkali basalts to olivine tholeiites (transitional basalt) which contain olivine as essential constituent together with clinopyroxene, plagioclase and glass. The basalt exhibits intergranular, intersertal, ophitic and subophitic relations. Amygdaloidal and glomerporphyritic textures are also observed. The basaltic rocks of different ages and from different localities are petrographically rather similar. Phenocrysts of olivine probably the result from slow cooling in crustal magma chambers prior to eruptions, suggesting that magmas ascended slowly through the crust. 109 samples have been carefully collected from various phases, some of these samples have been chosen for major and trace elements analyses, using XRF in order to determine the characteristics of themantle source and investigate crustal interaction. The major and trace elements revealed aslightly significant chemical diversity among the phases and within each phase. The normative classification of most of these rocks shows close agreement with their modal classification. A vague correlation between MgO and most major oxides in the studied samples suggests different degrees of partial melting rather than fractional crystallization. A characteristic feature of the studied volcanic rocks is the relatively constant ratios of certain incompatible trace elements (Nb/Zr, Rb/Zr), which provides strong evidence of a

Abstract: The growth rate of farmed European wild boars (Sus scrofa L.) is perceived to be very slow. However, there is no available information on the genetic potential of these animals in terms of potential lean tissue growth.The aim of the study was to determine the maximum capacity for protein deposition (operational PDmax) in wild boars under controlled environmental conditions. Four diets were formulated containing different levels of digestible energy (DE): 2.2, 2.4, 2.6, and 2.8 Mcal DE kg-1. All of the diets contained at least 5 g lysine per Mcal DE. Twenty purebred wild boars from a commercial farm of the same age (± 4 d) and with an initial liveweight of 27 ± 0.50 kg (mean ± standard error of the mean) were used in the study. At the beginning of the study (day 1), four animals were sacrificed and the carcasses were frozen without the digestive tract contents. The remaining animals were divided in foursomes and received each of the four diets over a 28-d period; they were then sacrificed and the carcasses were frozen without the digestive tract contents. All of the carcasses were ground and analyzed for DM, crude protein, ether extract, and ash. Protein deposition of the animals sacrificed on day 28 was determined as the difference between crude protein content estimated for the animals on day 1 using data from the animals sacrificed on day 1 and protein content of animals sacrificed on day 28. It was not possible to determine PDmax due to the genetic heterogeneity of the animals. Further studies on PDmax in wild boars must be carried out following genetic selection and breeding to produce more homogeneous animals. La tasa de crecimiento del jabalí Europeo (Sus scrofa L.) se considera muy baja. Sin embargo, no existe información respecto al potencial genético de estos animales en términos de aumento potencial de tejido magro. El objetivo del presente estudio fue determinar la capacidad de acumulación de proteína (PDmax operacional) en jabalíes bajo condiciones ambientales controladas. Se formularon cuatro dietas con distintos niveles de energía digestible (ED: 2,2; 2,4; 2,6; y 2,8 Mcal ED kg-1. Todas las dietas contenían al menos 5 g lisina por Mcal ED. Veinte jabalíes puros de la misma edad (± 4 d) provenientes de un plantel comercial, con un peso vivo inicial de 27 ± 0,5 kg (promedio ± error estándar de la media) fueron utilizados en el estudio. Al inicio del estudio (día 1) se sacrificaron cuatro animales, y posteriormente se congelaron sin el contenido del tractodigestivo. El resto de los animales recibieron las dietas (cuatro animales por cada diet
Possible Geological Reason for the Missing of the Oligocene Section in Sector (5) and Its Vicinity, Deryanah-Al Abyar Area, Al Jabal Al Akhdar, NE Libya  [PDF]

Open Journal of Geology (OJG) , 2013, DOI: 10.4236/ojg.2013.34037

The existing stratigraphic framework of the Eocene-Miocene in the study area (sector 5) shows limited temporal stratigraphic and structural resolution. Using this framework, it is difficult to unravel the influence of possible local tectonic movements and eustatic sea level changes on sedimentation. The precise influence of the onset of the possible Late Eocene-Early Oligocene orogenic phase, which caused inversion and uplift in the study area (sector 5), is also dubious as a result of the limited data. To improve the correlations and recognition of the Eocene to Oligocene successions in the area in question (from sector 1 to sector 8), a new stratigraphic interpretation, based on correlated lithostratigraphic columns from different outcrops, is presented. The changes in sedimentation and tectonic events in the study area can be correlated to time-equivalent sea level changes and tectonic uplift in Al Jabal Al Akhdar area, which suggests that the processes causing the sedimento/structural activity are of regional importance.

Revista chilena de historia natural , 2012,
Abstract: Se estudió la dieta del puma (Puma concolor)en los anos 1988 y 2004 en los faldeos de los volcanes Mocho y Choshuenco, pluviselva valdiviana, sur de Chile, a través de la identificación de ítemes-presas en sus heces y la búsqueda en terreno de carcasas de jabalí europeo (Sus scrofa).Se registra por primera vez al jabalí europeo entre los ítemes-presas del puma en Chile. El puma depredó predominantemente sobre juveniles y los porcentajes de consumo variaron entre un 17-37 % dependiendo del método empleado para analizar el contenido de presas presentes en sus heces. The diet of the American puma (Puma concolor)was studied in 1988 and 2004 in the foothills of the volcanoes Mocho and Choshuenco, Valdivian rainforest, southern Chile, through the identification of prey-items in their feces and field surveys of European wild boar (Sus scrofa)carcasses. We reported for the first time the invader European wild boar as a puma's prey in Chile. The puma preys mainly on juveniles and its percentage of consumed prey ranges between 17 and 37 % according to the method employed to assess the analyses of their feces prey contents.
