The widely held assumption that any important scientific information would be available in English underlies the underuse of non-English-language science across disciplines. However, is expected to bring unique and valuable information, especially disciplines where evidence patchy, for emergent issues synthesising an urgent challenge. Yet such contribution communities application rarely quantified. Here, we show studies provide crucial informing global biodiversity conservation. By screening...
How animals refine migratory behavior over their lifetime (i.e., the ontogeny of migration) is an enduring question with important implications for predicting adaptive capacity migrants in a changing world. Yet, our inability to monitor movements individuals from early life onward has limited understanding migration. The exploration–refinement hypothesis posits that learning shapes migration long-lived species, resulting greater exploratory followed by more rapid and direct movement during...
English is widely recognized as the language of science, and English-language publications (ELPs) are rapidly increasing. It often assumed that number non-ELPs decreasing. This assumption contributes to underuse in conservation practice, policy, especially at international level. However, articles published different languages poorly documented. Using local search systems, we searched for scientific on biodiversity from 1980 2018 15 non-English languages. We compared growth rate across In 12...
We determined the effects of past and future climate changes on distribution Montivipera raddei species complex (MRC) that contains rare endangered viper limited to Iran, Turkey Armenia. also investigated current MRC locate unidentified isolated populations as well evaluate effectiveness network protected areas for their conservation. Present was modeled based ecological variables model performance evaluated by field visits. Some individuals at newly identified showed uncommon morphological...
Migratory raptors rarely fly over stretches of water larger than 25 km, although different species undertake crossings varying lengths, depending mainly on their wing morphology. Oriental Honey‐buzzards c . 680 km the East China Sea in autumn from breeding areas Japan to wintering Southeast Asia, but avoid this long crossing spring. We investigated effects weather exceptional migratory behaviour and its seasonality through a maximum entropy niche modelling approach. used data collected...
Flying over the open sea is energetically costly for terrestrial birds. Despite this, over-water journeys of many birds, sometimes hundreds kilometres long, are uncovered by bio-logging technology. To understand how these birds afford their flights sea, we investigated role atmospheric conditions, specifically wind and uplift, in subsidizing flight at a global scale. We first established that ΔT, temperature difference between surface air, meaningful proxy uplift water. Using this proxy,...
Flapping flight is relatively costly for soaring birds such as raptors. To avoid flight, migrating raptors generally flying over water. As a result, all but one of the global raptor migration flyways are largely land. The East Asian oceanic flyway exception. Raptor species using this migrate by island-hopping, open ocean distances up to 300 km between islands. We used satellite telemetry data grey-faced buzzards Butastur indicus , that dominates southern part flyway, investigate geographical...
Thermal soaring birds extract energy from the atmosphere to achieve energetically low-cost movement. When encountering regions that are costly fly over, such as open seas, they should attempt adjust spatio-temporal pattern of their passage maximize extraction over these ecological barriers. We applied concept landscapes investigate dynamics availability sea for flight. specifically investigated how ‘energy seascape' may shape age-specific sea-crossing behaviour European honey buzzards,...

Summary We developed a habitat suitability model for wintering populations of the Asian Houbara Bustard Chlamydotis macqueenii in Iran and determined environmental variables affecting its occurrence. Our results indicate that various patches central, western eastern provide most suitable habitats Houbara. Annual precipitation, slope distance to croplands were important predicting also effects future climate changes on distribution Iran. Results showed will increase Iran, but considerably...
Achieving independence from parental care requires animals to learn about their environment while acquiring vital skills. The timing and type of the transition vary across species, with some achieving early, others rely on prolonged presumably mature develop When is delayed until juveniles reach a certain level skill, we can expect that skill acquisition rate proficiency will predict independence. Here, investigated whether soaring flight skills latency engage in extra-territorial excursions...
A 2-year study of the food habits Persian leopard was conducted in Sarigol National Park northeastern Iran, North Khorasan Province. Based on an analysis 52 scats, principal prey wild sheep (Ovis orientalis: frequency occurrence = 61.5%; relative 47.05%; biomass 53.96%), followed by pig (Sus scrofa: 23.07%; 17.64%; 25.38%) and goat (Capra aegagrus: 13.46%; 10.29%; 6.64%). The high proportion medium- large-size diet indicates favorable feeding conditions area. Habitat use determined using...
Migratory birds can be adversely affected by climate change as they encounter its geographically uneven impacts in various stages of their life cycle. While a wealth research is devoted to the on distribution range and phenology migratory birds, indirect effects optimal routes flyways, through changes air movements, are poorly understood. Here, we predict influence route long-distant migrant using an ensemble correlative modelling approaches, present future atmospheric data obtained from...

Divergent evolution between Western Rock Nuthatch Sitta neumayer and Eastern tephronota is widely recognized as the original case study of character displacement. However, in their contact zone Zagros Mountains, Iran, morphological differences important for niche segregation two species remain unknown. We investigated microhabitat use adaptations species, predicting that to different habitats these nuthatches have led spatial segregation. Seventy‐seven birds were captured measured allopatric...
Classifying the status of threatened species using tools such as IUCN Red List is a critical step for identifying at-risk species, and conservation planning at global sub-global levels. The requirement data on population trends, geographic ranges sizes has proved challenging to carry out national level, especially in countries with unstructured spatially limited monitoring schemes resources. In this study, we investigated repeatability risk assessments made under guidelines assessment level....
Summary The network of wetland systems in Iran provides valuable staging and wintering areas for waterbirds the African-Western Eurasian flyways. West Siberian/Caspian/Nile populations Anatidae (ducks, geese swans) regularly overwinter stop over Iran, are considered an economically culturally important group birds country. Conservation such migratory requires identification key threat factors impacting them throughout flyway. Since documented data on status threats facing very scarce, this...
The heterogeneity of the physical environment determines cost transport for animals, shaping their energy landscape. Animals respond to this landscape by adjusting distribution and movement maximize gains reduce costs. Much our current knowledge about dynamics focuses on factors external animal, particularly spatio-temporal variations environment. However, an animal’s internal state can significantly impact its ability perceive utilize available energy, creating a distinction between...
1 Abstract Soaring flight developed as a result of behavioural and morphological adaptations that allow birds to reduce the metabolic cost by harnessing energy available in atmosphere. Despite an increased attention given last decades physics ecology soaring flight, its study has been limited generally low spatio-temporal resolution atmospheric data. This constrained our ability quantify conditions soaring, understanding flexibility different uplift conditions. While use updraughts such...
