This dataset contains information on life history, wing morphological and reproductive traits of Pararge aegeria (L.). The data was collected from an eco-evolutionary study examining how male and female Pararge aegeria from woodland and agricultural landscape populations were affected by development on drought stressed host plants. The data of life history cover total development time and sex of the studied species. The data of wing morphology include total development time, sex, wing loading, the mean of forewing melanin, the mean of forewing:aspect ratio, and the total wing area. The data of female reproductive output are mean egg size, longevity, number of days until first egg laid, fecundity, arcine square root of the percentage of eggs hatched and the percentage of eggs hatched. All the data have adult mass, population name, landscape type and treatments. Further information can be found in Gibbs, M., Van Dyck, H., & Breuker, C. J. (2011).

The datasets were collected during experiments undertaken to examine survival rates and larval performance of Speckled Wood butterflies (Pararge aegeria) in different habitats (grassland and woodland). The experiments were carried out between 2008 and 2010 by the University of York, at sites in Yorkshire, Great Britain.

This dataset contains maternal reproductive output data, embryonic development data and offspring performance data for the Speckled Wood butterfly, Pararge aegeria. The data were collected from a laboratory experiment testing the hypothesis that repeat periods of intensive flight during female oviposition affects egg provisioning and reduces offspring performance when larval development occurs on drought stressed host plants. The experiment involved stimulating female butterflies to fly for 5 minutes for 3 periods during oviposition; removing eggs from 5 different days during oviposition to be monitored for hatching; and removing a larva on day of hatching to be reared on a drought stressed host plant. For each larva, development time from hatching to pupation, pupal mass and survival to eclose as an adult was recorded. On eclosion, each offspring adult was sexed and the thorax weighed. The overall aim of this experimental work was to explore one of the potential mechanisms for the impact of drought and habitat fragmentation on biodiversity.

[THIS DATASET HAS BEEN WITHDRAWN]. This dataset provides linear trends, over varying time periods, for the UK Butterfly Monitoring Scheme (UKBMS) Collated Indices of individual butterfly species across the UK. The main statistical values derived from a linear regression (slope, standard error, P-value) are presented for the entire time series for each species (1976 to 2015), for the last 20 years, and for the last decade. In addition a trend class, based on slope direction and its significance, and a percentage change for that time period are provided to describe the statistical trends. These trend data are provided for 59 UK butterfly species. Trends across different time series allow us to determine the long and short-term trends for individual species. This enables us to focus conservation and research and also to assess species responses to conservation already in place. The Centre for Ecology & Hydrology (CEH) and Butterfly Conservation (BC) are responsible for the calculation and interpretation of this trend datasets. The collection of the underlying UKBMS data is reliant on a large volunteer community. The UK Butterfly Monitoring Scheme is funded by a consortium of organisations led by the Joint Nature Conservation Committee (JNCC).

Butterfly data from the UK Environmental Change Network (ECN) terrestrial sites. Counts of individual species are recorded. These data are collected while walking a defined transect at all of ECN's terrestrial sites using a standard protocol. They represent continuous weekly records from 1993 to 2015. ECN is the UK's long-term environmental monitoring programme. It is a multi-agency programme sponsored by a consortium of fourteen government departments and agencies. These organisations contribute to the programme through funding either site monitoring and/or network co-ordination activities. These organisations are: Agri-Food and Biosciences Institute, Biotechnology and Biological Sciences Research Council, Cyfoeth Naturiol Cymru - Natural Resources Wales, Defence Science & Technology Laboratory, Department for Environment, Food and Rural Affairs, Environment Agency, Forestry Commission, Llywodraeth Cymru - Welsh Government, Natural England, Natural Environment Research Council, Northern Ireland Environment Agency, Scottish Environment Protection Agency, Scottish Government and Scottish Natural Heritage.

This dataset contains arthropod species presence and abundance data, species trait data and environmental data for arable reversion sites in southern England. A chronosequence of 52 arable grassland restoration sites and five target National Nature Reserve grassland communities were sampled for arthropods in 2014. These sites were located on calcareous soils. The majority of these sites were established as part of the South Downs Environmentally Sensitive Area (ESA), South Wessex Downs ESA, as well as through subsequent agri-environmental schemes including Countryside Stewardship or Higher Level agri-environment. Restoration sites ranged in age (1 to 30 years), habitat quality (e.g. sward structure and floral similarity to target grasslands), management (cutting and grazing) and surrounding landscape (isolation and cover of grassland). This environmental variation was captured and is included in the data set. Arthropods were identified across a wide range of trophic groups (detrititvores, herbivores, predators and pollinators). For arthropod species identified to species, information on functional traits is derived, including body mass, dispersal ability and trophic group.
