New insight into spatial ecology of Griffon Vulture (Gypsfulvus) on the Balkans provides opportunity for focusing conservation actions for a threatened social scavenger

Biodiversity Data Journal, 2021
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 ...

Spatially explicit poisoning risk affects survival rates of an obligate scavenger [PDF]

, 2018
Obligate scavengers such as vultures provide critical ecosystem services and their populations have undergone severe declines in Asia and Africa. Intentional poisoning is a major threat to vultures in Africa, yet the impact on vulture populations of ...

Effects of chronic browsing on life‐history traits of an irruptive large herbivore population

Population Ecology, EarlyView.
This study aimed to determine the relationship between diet quality, body mass, and size (hind foot length), and female reproduction and sought to identify the mechanism by which high density under severe food limitations is maintained. Our results demonstrated that sika deer introduced to Nakanoshima Island have maintained high densities through high ...

Egyptian Vulture in the Karatau Mountains and Adjacent Territories, Kazakhstan

Пернатые хищники и их охрана, 2022
Egyptian Vulture (Neophron percnopterus) is a globally threatened species. The northernmost limit of its breeding range is located in Kazakhstan and is fragmented into three large enclaves. The Karatau range is one such enclave. It was previously assumed

Combining transient dynamics and logistic‐asymptotic growth to study the recovery of two seabird populations after rat eradication

Population Ecology, EarlyView.
This study examines the demographic dynamics of two seabird populations on Tromelin Island, 15 years after the eradication of brown rats. The results indicate that these populations are in good health and are expected to continue growing until breeding sites are saturated in about a century.

The unpredictably eruptive dynamics of spruce budworm populations in eastern Canada

Population Ecology, EarlyView.
We examine historical population data for spruce budworm from several locations through the period 1930–1997, and use density‐dependent recruitment curves to test whether the pattern of population growth over time is more consistent with Royama's (1984; Ecological Monographs 54:429–462) linear R(t) model of harmonic oscillation at Green River New ...

Factors influencing the breeding density of Bearded Vultures, Egyptian Vultures and Eurasian Griffon Vultures in Catalonia (NE Spain): management implications [PDF]

Animal Biodiversity and Conservation, 2007
Using multivariate analyses we examined differences in breeding density of the Bearded Vulture Gypaetus barbatus, the Eurasian Griffon Vulture Gyps fulvus and the Egyptian Vulture Neophron percnopterus in NE Spain (Catalonia) in relation to trophic ...
