    Description

    TITLE: Analysis of eDNA Experimental data

    ACAN:

    The purpose of this Advance Contract Award Notice (ACAN) is to signal the government’s intention to award a contract for these services to Maelle Sevellec, Thorigné-Fouillard, France. 

    Before awarding a contract, however, the government would like to provide other suppliers with the opportunity to demonstrate that they are capable of satisfying the requirements set out in this Notice, by submitting a statement of capabilities during the ACAN posting period.

    If other potential suppliers submit a statement of capabilities during this ACAN posting period that meets the requirements set out in the ACAN, the government will proceed to a full tendering process on either GETS or through traditional means, in order to award the contract.

    If no other supplier submits, on or before the closing date, a statement of capabilities meeting the requirements set out in the ACAN, a contract will be awarded to the pre-selected supplier.

    INTRODUCTION:

    The Department of Fisheries and Oceans (DFO) has been conducting research to support the development genomic tools including environmental DNA (eDNA) which can be utilized for community-based coastal biodiversity monitoring program in the Canadian Arctic. This research will address the DFO Results Framework under the Aquatic Ecosystems core responsibility to conserve and protect Canada’s oceans and other aquatic ecosystems and species from human impact and invasive species.

    BACKGROUND:

    Environmental DNA (eDNA) has the ability to allow researchers to monitor and collect baseline biodiversity data on a large spatial and temporal scale in remote regions where data collection and monitoring is often limited. Although eDNA is a powerful tool for the biomonitoring of Arctic ecosystems, a better understanding of factors influencing eDNA variability is needed to improve the standardization of this method. DFO has conducted experimental work in several regions of the Arctic to examine the ecology of eDNA in Arctic marine coastal environments with respect to DNA recovery and species detection from water samples. Samples were previously collected in various locations and have been sequenced with taxonomic assignments.

    OBJECTIVES:

    DFO requires a contractor to conduct analyses of the eDNA data, write up data analysis methods, provide interpretation of results, and conduct background literature reviews/ write associated summaries on selected topic areas as outlined below.

    .

    WORK REQUIREMENT:

    The contractor will conduct analyses of the data, write up data analysis methods and interpretation of results, and conduct background literature reviews/ write associated summaries related to the following experiments: 

    1. Contrasting efficiency between zooplankton bulk metabarcoding versus water eDNA metabarcoding;
    2. Interannual variation in eDNA-based biodiversity indices across coastal locations;
    3. Evaluating water sample size versus volume effects on coastal eDNA-based estimates of coastal biodiversity; and
    4. eDNA-based evaluation of diversity in ship hull biofouling assemblages. This information will be important in improving the standardization of eDNA for coastal biodiversity sampling and development of community-based monitoring protocols

    1. Literature review/summary
