    <p>Effects of changing age-specific annual survival rates (top) and the constituents of productivity (bottom) on population growth rate of female soprano pipistrelles; the vital rates used are shown in brackets. In the absence of perturbation, the mean stochastic growth rate λ<sub>s</sub> was 0.997 i.e. essentially stable.</p

    Critical threshold of population parameters for female <i>Pipistrellus pygmaeus</i>, below which a population of 100 females is likely to become extinct within an arbitrary 500 years; figures in brackets show the vital rates used in the population models.

    <p>Shows the total number of day roost locations for bats at each site during exclusion experiments, the number of different roost types identified, and the proportional use (parentheses) of each roost type (calculated as the number of incidences that a bat was found roosting in a roost type divided by the total number of diurnal roost locations recorded for the site).</p

    Bird (from the BBS) and butterfly (from the UKBMS) abundance data used in the paper. Bird species names are given as BTO species codes. Sites where no study species were recorded have "NoTargetBirdRecorded" or "NoTargetButterflyRecorded" in the species column, and no value in the count column. NOTE - because this dataset has been processed as described in the paper, we strongly recommend researchers wishing to use BBS and UKBMS data in their own research to obtain data from the BTO (https://www.bto.org/research-data-services/data-services/data-request-system) and the UKBMS (http://www.ukbms.org/Obtaining.aspx) rather than use this file
