De Smet K. 2003. Cheetah in and Around Hoggar National Park in Central Sahara (Algeria)
de Smet K. 2003. Cheetah in and around Hoggar National Park in Central Sahara (Algeria). Cat News 38(Spring):22-4. Keywords: 1DZ/Acinonyx jubatus/cheetah/Hoggar NP/National Park/North Africa/prey/Sahara/status/ territorial behaviour Abstract: According the studies conducted in the late' 80s, in 2000 and in 2003, the cheetah is largely widespread in the Hoggar Mountains (Algeria) and its surroundings. Their numbers have probably risen since 2000. The potential preys of the cheetah are abundant. However, the cheetah is often killed by the Tuaregs despite their protection status. Cheetahs are reported to move on constantly from one valley to another, but have a territorial behaviour. The absence of competitors allows cheetah to hunt its preys without facing their robbery. The situation may be good in the Tassili Mountains too. D'après les études menées à la fin des années 80, en 2000 et en 2003 le guépard est largement répandu dans les montagnes du Hoggar (Algérie) et ses environs. Leur nombre a probablement augmenté depuis 2000. Les proies potentielles du guépard sont abondantes. Cependant, malgré son statut d'espèce protégée, le guépard est souvent tué par les Touaregs. D'après les observations, les guépards se déplacent constamment d'une vallée à l'autre, mais gardent un comportement territorial. L'absence de compétiteurs permet au guépard de chasser ses proies sans avoir à faire face à leur vol. La situation doit également être bonne dans les montagnes du Tassili.

Since 1997, all book proposals have been refereed by specialist reviewers as well as by the Society’s Books Editorial Committee. If the referees identify weaknesses in the proposal, these must be addressed before the proposal is accepted. Once the book is accepted, the Society Book Editors ensure that the volume editors follow strict guidelines on refereeing and quality control. We insist that individual papers can only be accepted after satisfactory review by two independent referees. The questions on the review forms are similar to those for Journal of the Geological Society. The referees’ forms and comments must be available to the Society’s Book Editors on request. Although many of the books result from meetings, the editors are expected to commission papers that were not presented at the meeting to ensure that the book provides a balanced coverage of the subject. Being accepted for presentation at the meeting does not guarantee inclusion in the book. -

Influence of Salt in the Tectonic Development of the Frontal Thrust
t Special section: Balancing, restoration, and palinspastic reconstruction Influence of salt in the tectonic development of the frontal thrust belt of the eastern Cordillera (Guatiquía area, Colombian Andes) Vanessa Parravano1, Antonio Teixell2, and Andrés Mora3 Abstract Geologic maps, seismic lines, and data from a dry exploration well were used to develop a new structural model for a segment of the eastern foothills of the Eastern Cordillera of Colombia, emphasizing the role of salt tectonics. Milestones in the deformation history of the Guatiquía foothills were studied by sequential section restoration to selected steps. Uncommon structural geometries and sparse salt occurrences were interpreted in terms of a kinematic evolution in which Cretaceous salt migration in extension produced a diapiric salt wall, which was subsequently welded during the main episodes of the Andean compression, when the salt wall was squeezed generating a large overturned flap. Salt-weld strain hardening resulted in breakthrough thrust- ing across the overturned flap in late deformation stages. We have evaluated a pattern of salt tectonics pre- viously unrecognized in the foothills thrust belt, which may be significant in other parts of the external Colombian Andes. Introduction We aim to provide an explanation for differences in The prolific thrust belt of the eastern foothills of the structural style in the EC external thrust belt.
