The dataset contains values on the prevalence and mean intensity of Batrachochytrium dendrobatidis (Bd) infection and ranavirus (Rv) infections in different combinations of common frog (Rana temporaria) and common toad (Bufo bufo) during mesocosm experiments executed in the summer of 2018, at the Institute of Zoology, Zoological Society of London (ZSL).

Data were generated from a mesocosm experiment to determine the extent to which non-reservoir hosts impact the maintenance and transmission of infections from parasites supported by reservoir hosts. The three host species were salamanders, Tree frogs (Hyla meridiensis) and Spiny toads (Bufo spinosus). The infection used was Batrachochytrium dendrobatidis (Bd). The experiment was executed in the late summer of 2017, at the Centre for Captive Breeding of Threatened Amphibians, located in Rascafria, Spain.

This dataset contains locations of worker bumblebees of five species (Bombus terrestris, B. lapidarius, B. pascuorum, B. hortorum, B. ruderatus) across an agricultural landscape centred on the Hillesden Estate, Buckinghamshire, UK. Locations were recorded in the field using a handheld GPS unit. Workers were non-lethally DNA sampled between June and August 2011, and genetic analysis used to confirm species and assign individuals to full-sib groups (colonies). Data were collected as part of a project led by the Centre for Ecology & Hydrology, funded under the Insect Pollinators Initiative.

Microsatellite data for five species of common and declining bumblebee (Bombus terrestris, B. lapidarius, B. pascuorum, B. hortorum and B. ruderatus) collected across the Hillesden Estate, Buckinghamshire, UK, in summer 2011. Worker genotypes were determined from individuals sampled across an agricultural landscape and queen genotypes were reconstructed from sampled worker offspring. Data were collected as part of a project led by the Centre for Ecology & Hydrology, funded under the Insect Pollinators Initiative.

Geographic distances between pairs of wild bumblebee colonies across an agricultural landscape centred on the Hillesden Estate, Buckinghamshire, UK. Colony locations were estimated using the foraging locations of workers sampled in summer 2011, genotyped and grouped into full-sib families. The spatial structure of five Bombus species (Bombus terrestris, B. lapidarius, B. pascuorum, B. hortorum and B. ruderatus) was determined, with inter-colony distances varying from 7 to 5264 metres. Data were collected as part of a project led by the Centre for Ecology & Hydrology, funded under the Insect Pollinators Initiative.
