Summary Vulture populations are in severe decline across Africa and prioritization of geographic areas for their conservation is urgently needed. To do so, we compiled three independent datasets on vulture occurrence from road-surveys, GPS-tracking, citizen science (eBird), used maximum entropy to build ensemble species distribution models (SDMs). We then identified spatial priorities Ethiopia, a stronghold vultures Africa, while accounting uncertainty our predictions. were able robust five the entirety including Critically Endangered, one Near Threatened species. show that occur highlands which provide particularly important habitat Bearded Gypaetus barbatus , Hooded Necrosyrtes monachus Rüppell’s Gyps rüppelli White-backed africanus Vultures, as well lowlands north-eastern valuable Egyptian Neophron percnopterus . One-third core was protected, followed by at one-sixth, all other one-tenth. Overall, only about one-fifth priority protected. Given there limited protection range widely, argue measures broad legislative scope will be necessary address drivers declines, poisoning, energy infrastructure, climate change, considering local social context aiding sustainable development.

Human-induced direct mortality affects huge numbers of birds each year, threatening hundreds species worldwide. Tracking technologies can be an important tool to investigate temporal and spatial patterns bird as well their drivers. We compiled 1704 records from tracking studies across the African-Eurasian flyway for 45 species, including raptors, storks, cranes, covering period 2003 2021. Our results show a higher frequency human-induced causes than natural taxonomic groups, geographical areas, age classes. Moreover, we found that remained stable over study period. From events with known cause (n = 637), three main were identified: electrocution (40.5 %), illegal killing (21.7 poisoning (16.3 %). Additionally, combined energy infrastructure-related (i.e., electrocution, power line collision, wind-farm collision) represented 49 % all events. Using random forest model, predictors group, geographic location (latitude longitude), human footprint index value at mortality. Despite conservation efforts, drivers in do not appear have declined last 15 years studied group species. Results suggest stronger actions address these threats reduce impacts on In particular, projected future development infrastructure is representative example where application planning, operation, mitigation measures enhance conservation.

Abstract Over millennia, human intervention has transformed European habitats mainly through extensive livestock grazing. “Dehesas/Montados” are an Iberian savannah-like ecosystem dominated by oak-trees, bushes and grass species that subject to agricultural uses. They a good example of how large-scale, low intensive transformations can maintain high biodiversity levels as well socio-economic cultural values. However, the role these human-modified play for individuals or living beyond their borders is unknown. Here, using dataset 106 adult GPS-tagged Eurasian griffon vultures ( Gyps fulvus ) monitored over seven years, we show breeding in western populations from Northern, Central, Southern Spain, France made long-range forays (LRFs) up 800 km converge threatened “dehesas” forage. There, wild ungulates provide large amounts carcasses, which available scavengers traditional exploitations rewilding processes. Our results highlight maintaining critical not only local but also long-term conservation services provided avian across continent.

Abstract Many apex scavenger species, including nearly all obligate scavengers, are in a state of rapid decline and there is growing evidence these declines can drastically alter ecological food webs. Our understanding how scavengers regulate populations mesoscavengers, those less‐efficient occupying mid‐trophic levels, improving; yet, has been no comprehensive evaluation the around competitive release species by loss scavengers. Here we present current that supports mesoscavenger hypothesis, increase mesoscavengers carrion face declining We provide two models dynamics to demonstrate hypothesis consistent with theory. further examine human well‐being implications decline, removal disease regulation services.

Abstract Background Fire strongly affects animals’ behavior, population dynamics, and environmental surroundings, which in turn are likely to affect their immune systems exposure pathogens. However, little work has yet been conducted on the effects of wildfires wildlife disease. This research gap is rapidly growing importance because becoming globally more common severe, with unknown impacts disease unclear implications for livestock human health future. Results Here, we discussed how could influence susceptibility infection wild animals, potential consequences ecology public health. In our framework, outlined habitat loss degradation caused by fire defenses, behavioral demographic responses pathogen exposure, spread, maintenance. We identified relative unknowns that might dynamics unpredictable ways (e.g., through altered community composition free-living parasites). Finally, avenues future investigations fire-disease links. Conclusions hope this review will stimulate much-needed role wildfire influencing disease, providing an important source information wake other natural disasters, encouraging further integration fields ecology.

Nature's contribution to people (i.e. ecosystem services) is becoming integral conservation science and policy, yet our knowledge restricted only a few services taxa. Vultures (family: Accipitridae Cathartidae), most of which are threatened with extinction, have been touted for delivering regulation maintenance via their capacity rapidly consume organic matter. As such, appellation as "nature's clean-up crew" has become very popular. However, comprehensive evaluation the supporting evidence such was absent from published literature. We performed systematic review assessment quantify global vultures towards over 20 disservices. Our analysis determined critical imbalance in scope focus research. In contrast birds' popularised image cleaners environment, we found weak support any vultures. Moreover, studies on disservices were prominent. The supported by strong cultural, although even these evidenced limited number studies.

Proactive approaches are typically more cost-effective than reactive ones, and this is clearly the case for biodiversity conservation. Research conservation actions Old World vultures followed large population declines, particularly in Asia Africa. These clear examples of intensive management. We here contend that there signs a potential upcoming continental vulture crisis New World. Word share many threats have decimated their counterparts, such as toxicosis from poisoning lead. At same time, we show quantitative data on key demographic action aspects largely lacking vultures, those restricted to Neotropics. This knowledge gap prevents us quantifying turn, design effective management mitigate prevent further declines. Essentially, if current gaps not filled rapidly, will miss opportunity apply proactive propose set Americas.
