title: Leech blood-meal iDNA reveals differences in Bornean mammal diversity across habitats

description: <b>Description: </b>This data set includes the data used in Drinkwater et al. (2020) Leech blood-meal iDNA reveals differences in Bornean mammal diversity across habitats, submitted to Molecular Ecology. There are three sets of data based on the biomonitoring of mammals using iDNA extracted from leeches collected across the SAFE project (and DVCA) in 2016. At each site in the SAFE landscape 20 minute handsearches took place within the boundaries of fixed 25m2 vegetation plots. For these analyses we only used Haemadipsa picta individuals, as previous studies have revealed species differences between H. picta and H. zeylanica in the SAFE area. With metabarcoding techniques, first we extracted and amplified the 16S rRNA region of mammal DNA, from site-matched pools of leeches using PCR and specific mammal primers. NGS sequencing was used and the short fragments were then identified using in silico PCR with ecoPCR and OBITOOLS (metabarcoding packages) to assign taxonomy to the unknown sequences. We then analysed diversity in different habitats across the landscape and included microclimate data, from LiDAR scans of the landscape as variables which could impact the detection of mammals. <b>Project: </b>This dataset was collected as part of the following SAFE research project: <b>The effects of rainforest fragmentation on mammal community assemblages using leech blood-meal analysis</b><b>Funding: </b>These data were collected as part of research funded by: NERC (Standard grant , NE/K016148/1)NERC (Independent research grant, NE/S01537X/1)This dataset is released under the CC-BY 4.0 licence, requiring that you cite the dataset in any outputs, but has the additional condition that you acknowledge the contribution of these funders in any outputs.<b>Permits: </b>These data were collected under permit from the following authorities:Sabah Biodiversity Council (Research licence JKM/MBS.1000 2/2 (34))Sabah Biodiversity Council (Research licence JKM/MBS.1000 2/3 JLD.2 (107))Sabah Biodiversity Council (Export licence JKM/MBS.1000 2/3 JLD.3 (44))Danum Valley Conservation Area (Research licence YS/DVMC/2016/253)<b>XML metadata: </b>GEMINI compliant metadata for this dataset is available here<b>Files: </b>This consists of 1 file: Drinkwater2020-iDNA_diversity3.xlsx<b>Drinkwater2020-iDNA_diversity3.xlsx</b>This file contains dataset metadata and 3 data tables:<b>UNFILTERED Taxonomic assignment of iDNA sequences</b> (described in worksheet ecoTAG_output_raw)Description: UNFILTERED This dataset is the raw output of the in silico PCR using the programs ecoPCR and the OBITOOLS package. The exact primers are matched against all mammal sequences in GenBank (NCBI) using a minimum of three mismatches between primer and query sequence and a quality filter of a minimum identity of 0.95.

The value is a count of the numebr of time the unique sequence for that taxon was recorded in the pool. Geographically implausible mammals have been removed and taxa which agree per site have been collapsed. This give a detections by pool matrix. For analyses these counts were converted into presence/absence data.
