The overarching aim of the atlas is to communicate potential risks climatic change future European butterflies. main objectives are to: (1) provide a visual aid discussions on climate and impacts biodiversity thus contribute risk communication as core element assessment; (2) present crucial data large group species which could help prioritise conservation efforts in face change; (3) reach broader audience through combination new scientific results with photographs all treated some straight...

Bumble bees represent one of the most important groups pollinators. In addition to their ecological and economic relevance, they are also a highly charismatic group which can help increase interest people in realizing, enjoying conserving natural systems. However, like animals, bum- ble sensitive climate. this atlas, maps depicting potential risks climate change for bumble shown together with informative summary statistics, back- ground information picture each European species.

ABSTRACT Aim We investigate the importance of interacting species for current and potential future distributions, influence their ecological characteristics on projected range shifts when considering or ignoring species, consistency observed relationships across different global change scenarios.

Abstract Aim To assess the effectiveness of protected areas in preventing biodiversity decline. We first test whether species richness butterfly assemblages is higher within European Natura 2000 (N2000) sites than their surroundings. then temporal trends and these differ inside outside N2000 network. Location Germany, Europe. Methods utilized generalized linear mixed‐effects models (GLMM) to analyse an 11‐year data series on collected 245 transects across located sites, comprising a total...

Trait-based analyses explaining the different responses of species and communities to environmental changes are increasing in frequency. European butterflies an indicator group that responds rapidly with extensive citizen science contributions documenting abundance distribution. Species traits have been used explain long- short-term climate, land-use vegetation changes. Studies often characterised by limited trait sets being used, risks relative roles not fully explored. Butterfly...

Summary The rapid expansion of systematic monitoring schemes necessitates robust methods to reliably assess species' status and trends. Insect poses a challenge where there are strong seasonal patterns, requiring repeated counts abundance. Butterfly ( BMS s) operate in an increasing number countries with broadly the same methodology, yet they differ their observation frequency used compute annual abundance indices. Using simulated observed data, we performed extensive comparison two...

Detailed information on species' ecological niche characteristics that can be related to declines and extinctions is indispensable for a better understanding of the relationship between occurrence performance wild species their environment and, moreover, an improved assessment impacts global change. Knowledge such as habitat requirements already available in literature butterflies, but about climatic still lacking. Here we present unique dataset 397 European butterflies representing 91% (see...

This report presents the European Grassland Butterfly Indicator, based on national Monitoring Schemes (BMS) in 19 countries across Europe, most of them Union. The indicator shows that since 1990 till 2011 butterfly populations have declined by almost 50 %, indicating a dramatic loss grassland biodiversity. also means situation has not improved first version published 2005.

International trade of species facilitates the establishment nonnative organisms. Highlighting areas potentially suitable for invasive (risk areas) allows effective importation regulations to prevent spread and potential damage caused by such species. Species distribution models (SDMs) are commonly used predict risk but they usually disregard intraspecific differentiation corresponding differences in climatic requirements. We Bombus terrestris as an example a traded developed SDMs at...

Abstract Aim Conventional species distribution models (SDMs) usually focus on the level but disregard intraspecific variability. Phylogeographic structure and evolutionary significant units (ESU) have been proposed as pragmatic proxies to incorporate differentiation in SDMs. Nevertheless, efficiency of using these SDMs has poorly investigated. We analysed how projections current future climatically suitable areas can be affected when ESU‐based or lineage‐based compared a species‐level model....

Abstract Despite large numbers of reintroduction projects taking place and the high cost involved, there is a generally low success rate. Insects in particular are understudied within ecology, with guidelines focusing on more iconic vertebrate taxa. Species distribution models (SDMs) examine associations between species observations environmental variables to find conditions which populations could survive. This study utilises two frequently used SDM approaches, regression model (general...

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...

In 2005 a nationwide monitoring scheme for butterflies (and diurnal moths) was launched in Germany.

The core objectives are (a) to provide central element analysis biodiversity (b) investigate develop role indicators state biodiversity. Both aims at regional, national,...

Abstract The Irano‐Turanian (IT) floristic region is considered an important center of origin for many taxa. However, there a lack studies dealing with typical IT genera that also occur in neighboring areas. species‐rich monocot genus Gagea Salisb. shows diversity and distribution adjacent regions, therefore representing good study object to investigate spatial temporal relationships among its areas (East Asia, Euro‐Siberia, Himalaya, Mediterranean).
