The Social Costs of Keystone Species Collapse: Evidence from the Decline of Vultures in India

Social Science Research Network
Scientific evidence has documented we are undergoing a mass extinction of species, caused by human activity. However, allocating conservation resources is difficult due to scarce evidence on damages from losing individual species.

Traditional belief systems and trade in vulture parts are leading to the eradication of vultures in Nigeria: an ethno-ornithological study of north-central Nigeria

Ostrich, 2021
The population of various species of vultures are declining rapidly across Africa, with noticeable declines in most areas including protected areas. This sudden decline of vultures in African countries, especially Nigeria, is quite alarming.

The presence of black vultures at the calving sites and its effects on cows’ and calves’ behaviour immediately following parturition

Animal, 2013
Black vultures (Coragyps atratus) are often present near calving sites, and under this situation they may play a positive role by removing animal carcasses and afterbirth or a negative role by attacking neonate calves or disturbing cow–calf behaviours ...

Recent applications and advances of African Vultures Optimization Algorithm

Artificial Intelligence Review
The African Vultures Optimization Algorithm (AVOA) is a recently developed meta-heuristic algorithm inspired by the foraging behavior of African vultures in nature. This algorithm has gained attention due to its simplicity, flexibility, and effectiveness

Current policies in Europe and South Asia do not prevent veterinary use of drugs toxic to vultures

Ecological Solutions and Evidence
Population declines of vultures of the genus Gyps in the Indian Subcontinent in the 1990s and 2000s were among the most rapid global population declines recorded for any bird species.

The non-steroidal anti-inflammatory drug nimesulide kills Gyps vultures at concentrations found in the muscle of treated cattle

bioRxiv, 2021
Throughout South Asia, cattle are regularly treated with non-steroidal anti-inflammatory drugs (NSAIDs) and their carcasses are left for scavengers to consume.

De novo synthesis of short‐chain aldehydes and hydrocarbons secreted by the brown marmorated stink bug Halyomorpha halys

FEBS Open Bio, EarlyView.
The brown marmorated stink bug, Halyomorpha halys, mainly secretes 4‐oxo‐(E)‐2‐hexenal, (E)‐2‐decenal, dodecane and tridecane, a mixture representative of that released by many heteropterans. We demonstrated that H. halys can synthesise these secretory components de novo using dietary glucose.

Survival rates of wild and released White‐rumped Vultures (Gyps bengalensis), and their implications for conservation of vultures in Nepal

Ibis
Beginning in the mid‐1990s, populations of three species of Gyps vultures declined by more than 97% in South Asia in little more than a decade, caused by unintentional poisoning by the non‐steroidal anti‐inflammatory drug (NSAID) diclofenac.
