Résumé :

Scavenging guilds often have several trophic levels with varying dominance and intra-guild predation, competition, and interaction. Apex predators can control subordinate predators by limiting their numbers and affecting behaviour but also supply a continuous food source by abandoning carcasses. Camera traps monitored the scavenger guild in Alpe di Catenaia, Tuscan Apennine, for three years to determine intraguild interactions and the behaviour response. Wild boar visited most feeding sites but only scavenged in 1.4% of their visits. Red fox was the most frequent scavenger, traded vigilance an

Résumé :

La aparición de pueblos y ciudades ha creado un nicho carroñero potencial para oportunistas al que una serie de especies de aves, interesadas en la explotación de esta fuente de alimento, se han adaptado. La información obtenida en Europa noroccidental evidencia el éxito de un pequeño grupo de carroñeros urbanos, especialmente depredadores y necrófagos, donde se incluyen especies cuyas áreas de distribución se han visto marcadamente reducidas durante los últimos siglos.

Résumé :

Cadaver decomposition islands around animal carcasses can facilitate establishment of various plant life. Facultative scavengers have great potential for endozoochory, and often aggregate around carcasses. Hence, they may disperse plant seeds that they ingest across the landscape towards cadaver decomposition islands. Here, we demonstrate this novel mechanism along a gradient of wild tundra reindeer carcasses. First, we show that the spatial distribution of scavenger faeces (birds and foxes) was concentrated around carcasses. Second, faeces of the predominant scavengers (corvids) commonly cont

Wind energy has become one of the fastest-growing renewable electricity sources globally, and this trend is expected to continue. However, wind turbines cause avian mortality when birds collide with these structures.

This uncertainty is often attributed to searcher inefficiencies or scavenger losses. Furthermore, data regarding the effectiveness of active bird mortality mitigation at these facilities are a

Experimental findings which support a functional connection between the pineal gland and immune system in mammals and birds are summarized. Developmental and age-related changes in pineal gland function appear, at least partially, to be related with immune system efficiency. Mechanisms whereby melatonin influences immune system function are complex, but include participation of mediators (endogenous opioids, cytokines, hormones, zinc pool) as well as specific binding sites on the immune cells.

Résumé :

Due to the fact that they consume carrion, vultures serve an important ecological purpose in addition to being very reliable indicators of the ecosystem's overall health. They are the only group of vertebrates that have been documented as being obligate scavengers. There are nine distinct species of old world vultures found in India. The Red-headed Vulture (RHV) is a species of vulture found in the United States that reaches a height of 2,000 meters throughout the nation. The inquiry was conducted in Madhya Pradesh, popularly known as Bundelkhand, and Uttar Pradesh, two states in India. The re

(Uploaded by Plazi for the Bat Literature Project) Small wind turbines (SWTs) are an increasingly popular means to generate renewable energy worldwide. Flexibility in size and design allow SWTs to be installed in a much wider range of settings compared to large wind turbines. While large wind turbines can cause substantial mortality of birds and bats, the extent and correlates of such collision mortality at SWTs have not been quantified. Thus, siting decisions for SWTs are currently made with considerable uncertainty of their impact on wildlife. We combined field data and questionnaire surveys

Résumé :

The pterosaur is the first known vertebrate clade to achieve powered flight. Its hyoid apparatus shows a simplification similar to that of birds, although samples of the apparatus are rare, limiting the ability to make an accurate determination. In this study we reveal a new pterosaur specimen, including the first definite basihyal. Through the comparison of pterosaur hyoids, a trend has been discovered for the shortened hyoid relative to the length of the skull, indicating a diminished role of lingual retraction during the evolution of the pterosaur.

Abstract The Asian water monitor (Varanus salvator) is a large generalist predator and scavenger lizard. This species has a widespread distribution throughout South and Southeast Asia and is frequently encountered around the edges of urban settlements. Here, we present information on diet diversity and habitat utilisation of a population of Asian water monitors inhabiting the University of Malaysia Terengganu campus located on the east coast of mainland Malaysia. The stomach contents of 30 Asian water monitors were examined by stomach flushing, and 47.6% of stomach contents was mangrove crab,

Résumé :

The knowledge in the behaviour and movement of endangered species is of key importance for the precise targeting and assessing the efficiency of nature conservation actions, especially considering vultures, which explore vast areas to locate ephemeral and unpredictable food resources. Therefore, a total of 51 Griffon Vultures (<i>Gyps fulvus</i>) from both the re-introduced population and the autochthonous Balkan Peninsula (Balkans) colonies have been tagged with GPS/GSM transmitters in recent years, in order to study their seasonal and spatial distribution. The current study presents the anal

Résumé :

Over the last century, marine mammals have been dramatically reduced in the world's oceans. We examined evidence that this change caused dietary and foraging pattern shifts of the Andean condor ( Vultur gryphus ) in Patagonia. We hypothesized that, after the decrease in marine mammals and the increase in human use of coastlines, condor diet changed to a more terrestrial diet, which in turn influenced their foraging patterns. We evaluated the diet by means of stable isotope analysis ( δ 13 C, δ 15 N and δ 34 S) of current (last decade) and historical (1841–1933) feathers. We further evaluated t

Résumé :

Hypoxic pulmonary vasoconstriction (HPV) is an adaptive response that diverts pulmonary blood flow from poorly ventilated and hypoxic areas of the lung to more well-ventilated parts. This response is important for the local matching of blood perfusion to ventilation and improves pulmonary gas exchange efficiency. HPV is an ancient and highly conserved response, expressed in the respiratory organs of all vertebrates, including lungs of mammals, birds, and reptiles; amphibian skin; and fish gills. The mechanism underlying HPV and how cells sense low Po2 remains elusive. In perfused trout gills (

Résumé :

Trypanosoma cruzi, the protozoan causative of Chagas disease, is primarily transmitted through blood-sucking insects and infects mammalian and some reptilian hosts. In Chile, insects of the Mepraia genus are key vectors of T. cruzi in its wild transmission cycle. High prevalence and mixed infection of T. cruzi lineages have been reported in a Mepraia population on Santa María Island in the Atacama Desert. However, no small mammals have been reported. The island’s vertebrate community is dominated by the lizard Microlophus atacamensis and marine and scavenger birds. This study aimed to research

Résumé :

This research aims to analyze the reality of the lives of scavengers, the problem of poverty that holds them hostage, and the role of the church in empowering scavengers. The scavenger profession is carried out due to the acute poverty problem experienced by urban communities. Scavengers work by picking up rubbish, such as aqua glass, bottles, iron, and various other rubbish that can be sold, to meet economic needs. Scavengers are always viewed negatively as poor people and often receive discrimination from society in general. Using qualitative research methods, this research conducted observa
