Animals may perceive humans as a form of predatory threat, disturbance, triggering behavioral changes together with the activation physiological stress responses. These adaptive responses allow individuals to cope stressful stimuli, but repeated or long-term exposure disturbances have detrimental individual- and population-level effects. We studied effects human activities, particularly hunting, on behavior status near-threatened nongame steppe bird, little bustard. Using semiexperimental...
Abstract Farmland bird populations have declined sharply due to agricultural intensification. In Europe, these negative population trends been linked the loss of semi‐natural vegetation types, particularly fallow land. The work Sanz‐Pérez et al. (2019) has far‐reaching implications for conservation farmland biodiversity. We argue that it supports a new paradigm understanding and management fallows should be integrated into forthcoming post‐2020 Common Agricultural Policy (CAP). Following...
The next reform of the EU Common Agricultural Policy (CAP) for period 2021-2027 (currently extended to 2023-2030) requires approval by European Commission a Strategic Plan with environmental objectives each Member State. Here we use best available scientific evidence on relationships between agricultural practices and biodiversity delineate specific recommendations development Spanish Plan. Scientific shows that Spain should (1) identify clear regional targets landscape-level measures needed...
European green agricultural policies have been relaxed to allow cultivation of fallow land produce animal feed and meet shortfalls in exports from Ukraine Russia. However, conversion semi-natural habitats will disproportionately impact long term biodiversity food security.
Summary Many European farmland bird populations are rapidly declining because of agricultural intensification and land-use changes. Robust estimates population sizes trends, habitat use, protected area coverage within the distribution range crucial to inform conservation management threatened species. Here we report on results 2019 Black-bellied Sandgrouse Pterocles orientalis (BBS) survey promoted coordinated by SEO/BirdLife update its breeding distribution, size, trends in continental...
Abstract Arthropods play key roles in ecosystems as pollinators or food resources for many birds. The decline arthropods farmland due to agricultural intensification is related negative population trends Semi‐natural areas such fallow land are valuable habitats arthropod communities farmland, but the potential of these boost biodiversity greatly depends on their management. We used a field experiment explore mechanisms behind effects mechanical management high conservation value land. GLMMs...
Species distribution patterns are determined not only by habitat preferences but also biotic factors. Particularly, the presence of conspecifics may yield different types benefits and costs for individuals involved. This study analyses spatial Little Bustard families during breeding season in relation to male core areas three Spanish populations species. A compositional analysis is used evaluate selection most preferred females with offspring. Spatial were performed proximity displaying...
Abstract Interspecific competition is a dominant force in animal communities that induces niche shifts ecological and evolutionary time. If occurs, expansion can be expected when the competitor disappears because resources previously inaccessible due to competitive constraints then exploited (i.e., release). Here, we aimed determine potential effects of interspecific between little bustard ( Tetrax tetrax ) great Otis tarda using multidimensional approach with habitat distribution data. We...
In order for competing species to coexist, segregation on some ecological niche component is required and often mediated by differential habitat use. When unequal competitors are involved, the dominant tends displace subordinate one its less preferred habitat. Here, we use isodars, an approach which reflects evolutionary stable strategies of selection, evaluate whether interspecific competition between two with distinct preferences, little bustard Tetrax tetrax great Otis tarda, modulates...
Biotic interactions and land uses have been proposed as factors that determine the distribution of species at local scale. The presence heterospecifics may modify habitat selection pattern individuals this important implications for design effective conservation strategies. However, proposals are often focused on a single flagship or umbrella taken representative an entire assemblage requirements. Our aim is to identify evaluate role coexistence areas scale tools, by using data two...
Abstract Competition is a prominent mechanism driving population dynamics and structuring community assemblage, which can be investigated by linking shifts in species’ ecological niche the densities of sympatric species because release from competitive constraints density‐dependent process. In this work we determine how steppe passerine segregates their niches evaluate role competition inducing changes species. We built multidimensional (with Gaussian kernel density estimators) using data on...
Abstract Increasing abundance of large ungulates is raising human-wildlife impacts and the effectiveness recreational hunting to reduce their population growth increasingly questioned. We report on long-term trends (> 15 years) in wildlife-vehicle collisions (WVC) bags, associations between annual rate WVC that bags for three – wild boar, red deer, roe deer grey wolf northwest Spain evaluate regulating capacity at spatial scale. Wildlife-vehicle increased by 332% 16 years 91% all traffic...
Traffic noise is an associated effect of roads, potentially impacting wildlife. In the case birds, it may alter spatial distribution, behavioural responses and physiological status, frequently masking acoustic signals conspecifics predators. We analyse how road traffic affects habitat selection Little Bustard males during breeding season, when they produce brief territorial snort calls. The study site in a typical agrarian area central Spain, markedly affected by noise. A map was built using...

Habitat degradation and climate change are major threats to the long-term persistence of reptile populations. However, their roles on primary productivity instability remain unclear at certain scales. Besides, design protected areas has often overlooked reptiles or assumed that ecological requirements represented under umbrella more charismatic species. Here, we assess vulnerability high diversity in Iberian Peninsula global using data from satellite imagery. We focused productivity,...
Atenuar el declive de las aves agrarias es uno los objetivos la nueva Política Agraria Común (PAC) 2023-2027. Para ello, planes estratégicos Estados miembros deben incluir medidas específicas dentro su Arquitectura Verde (condicionalidad reforzada, eco-regímenes y ayudas desarrollo rural) para abordar este objetivo, cuya efectividad debe ser evaluada directamente. Mediante una evaluación ex-ante, examinamos si incluidas en plan estratégico español PAC (PEPAC) favorecer a podrían...
