Although most Old World vulture species are declining or threatened in Asia and Africa, in Europe healthy vulture populations still exist. However, recent application of sanitary legislation that has greatly reduced the availability of animal carcasses is now a concern for conservationists. Until now, no studies have been undertaken to determine long-term dietary shifts in these species in Euro...

The Cinereous Vulture, Aegypius monachus, formerly known as the Black Vulture, is classified as near-threatened at world level (Collar et al. 1994). A. monachus is widely distributed, with a continuous range extending from Europe and North Africa through the Middle East to Mongolia and China (Appak, 1992). It has since been extirpated in most of its European range. Its only remaining stronghold...

Knowledge of black vulture (Coragyps atratus) and turkey vulture (Cathartes aura) spatial ecology is surprisingly limited despite their vital ecological roles. Fine-scale assessments of space use patterns and resource selection are particularly lacking, although development of tracking technologies has allowed data collection at finer temporal and spatial resolution. Objectives of this study we...

A presumptive diagnosis of secondary ethylene glycol toxicity in a female Turkey vulture (Cathartes aura) was made depending on the histopathological changes found in the renal tubules and presence of Isospora spp. of non-avian type within the colon. To the best of our knowledge, this is the first reported case of possible secondary ethylene glycol toxicity in a Turkey vulture in Louisiana Stat...

Biodiversity losses are increasing as a consequence of negative anthropogenic effects on ecosystem dynamics. However, the magnitude and complexity of these effects may still be greatly underestimated. Most Old World vultures have experienced rapid population declines in recent years. In Europe, their immediate conservation depends on changes in health regulations affecting the availability of f...

Key findings The results show that 77.4% of respondents rear an average of 2.97 livestock unit (LSU) per household. More than half of respondents who rear livestock (53.82%) dump livestock carcasses in the open fields. Ethnicity, age, education status, gender, livestock unit and involvement in conservation activities are the most significant predictors for the positive attitudes towards vulture...

Vehicle Routing problem (VRP) is the challenging and sophisticated optimization problem which can be solved by various approaches like Exact methods, metaheuristic optimization algorithm and Mathematical approaches including linear and integer programming Techniques. Exact algorithms can only solve relatively small problems of VRP. Several approximate algorithms have proven successfully to find...

Abstract Remains of at least three species large aegypiine vultures from early Palaeolithic and Iberomaurusian Ifri n’Ammar, Morocco are the first substantial fossil record these taxa in Maghreb. They can be tentatively referred to two extant Aegypius monachus (Cinereous Vulture) Gyps fulvus (Griffon Vulture), extinct melitensis . Few fragments remarkably bones may belong especially specimens A...

The aim of the present study was to characterize a collection of Escherichia coli strains isolated from asymptomatic griffon vulture (Gyps fulvus) during a reintroduction program in the southeast of Spain, in order to establish if griffon vulture could play a role in the spread of resistant or potentially pathogenic E. coli strains. For this purpose, 14 E. coli strains obtained from 10 griffon ...

The Bearded Vulture (Gypaetus barbatus) is an endangered species in Europe that feeds almost exclusively on bone remains of wild and domestic ungulates. In this paper, we present a model of an ecosystem related to the Bearded Vulture in the Pyrenees (NE Spain), by using P systems. The evolution of six species is studied: the Bearded Vulture and five subfamilies of domestic and wild ungulates up...
