Effective policies to halt biodiversity loss require knowing which anthropogenic drivers are the most important direct causes. Whereas previous knowledge has been limited in scope and rigor, here we statistically synthesize empirical comparisons of recent driver impacts found through a wide-ranging review. We show that land/sea use change dominant worldwide. Direct exploitation natural resources ranks second pollution third; climate invasive alien species have significantly less than top two...

Efficient management of biodiversity requires a forward-looking approach based on scenarios that explore changes under future environmental conditions. A number ecological models have been proposed over the last decades to develop these scenarios. Novel modelling approaches with strong theoretical foundation now offer possibility integrate key and evolutionary processes shape species distribution community structure. Although is affected by multiple threats, most studies addressing effects...

Based on an extensive model intercomparison, we assessed trends in biodiversity and ecosystem services from historical reconstructions future scenarios of land-use climate change. During the 20th century, declined globally by 2 to 11%, as estimated a range indicators. Provisioning increased several fold, regulating decreased moderately. Going forward, policies toward sustainability have potential slow loss resulting change demand for provisioning while reducing or reversing declines...

Abstract Temporal baselines are needed for biodiversity, in order the change biodiversity to be measured over time, targets conservation defined and progress evaluated. Limited information is widely recognized as a major barrier identifying temporal baselines, although comprehensive quantitative assessment of this lacking. Here, we report on that could drawn from monitoring schemes Europe compare those with rise important anthropogenic pressures. Most were initiated late 20 th century, well...

Abstract. To support the assessments of Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES), IPBES Expert Group Scenarios Models is carrying out an intercomparison biodiversity ecosystem services models using harmonized scenarios (BES-SIM). The goals BES-SIM are (1) to project global impacts land-use climate change (i.e., nature's contributions people) over coming decades, compared 20th century, a set common metrics at multiple scales, (2) identify model...

Abstract Aim Species distribution models often assume a changing climate (dynamic variables) but unchanged land use (static to estimate future species shifts. However, scenarios of projected change are available calculate dynamic variables. Surprisingly, the importance using instead static variables when projecting potential distributions under remains largely unexplored. We tested whether joint inclusion and altered projection compared with classical approach assuming use. Location E urope...

It is now widely recognized that climate and land use changes are among the most important threats to biodiversity ecosystem services (Maxwell, Fuller, Brooks, & Watson, 2016; Scheffers et al., 2016). Biodiversity models scenarios developed explore possible future impacts of these (Thuiller 2013; Urban Such approaches needed inform decision-makers on conservation or management options anticipate response change.

SUMMARY In Europe, and particularly in the Mediterranean Basin, abandonment of traditional land-use practices has been reported as one main causes decline for open-habitat species. Data from large-scale bird butterfly monitoring schemes north-east Iberian Peninsula were used to evaluate impact that land had on local biodiversity. Species’ habitat preferences, along a gradient open forest habitats, significantly related population trends: both birds butterflies, species showed most marked...

In human-altered environments, organisms may preferentially settle in poor-quality habitats where fitness returns are lower relative to available higher-quality habitats. Such ecological trapping is due a mismatch between the cues used during habitat selection and quality. Maladaptive settlement decisions occur when time-constrained have rapidly evaluate quality based on incomplete knowledge of resources conditions that will be later season. During three-year study, we examined...

The climatic preferences of the species determine to a large extent their response climate change. Temperature have been shown play key role in driving trends animal populations. However, relative importance temperature and precipitation is still poorly understood, particularly systems where ecological processes are strongly constrained by amount timing rainfall. In this study, we estimated played determining population for birds butterflies Mediterranean area. Trends were derived from...

Species populations naturally fluctuate, yet long-term trend analysis can reveal patterns of success, decline, or stability under global change pressures. While responses to climate are well-documented, its synergy with another major driver, urbanization, remains understudied. Here, we analyzed monitoring data from over 8,400 145 butterfly species across Europe, representing a high diversity traits, assess population trends in response and urbanization. We examined how vary between urban...

Abstract Aim Species distribution models built with geographically restricted data often fail to capture the full range of conditions experienced by species across their entire area. Using such predict shifts under future environmental change may, therefore, produce biased projections. However, restricted‐scale have potential include a larger sample taxa for which are available and provide finer‐resolution projections that better applied conservation planning than forecasts broad‐scale...
