Agriculture as a Measure of Biodiversity
Traditionally, agriculture = downgraded
ecosystem a poor relation to the ideal
biodiverse ecosystem of "Nature" Agriculture has its own
challenges Reduced diversity - easily
discovered by pests Monocultures - species, cultivars Spatial regularity - row crops,
crowding Selection pressure: environment
modified by use of pesticides, resistant cultivars, planting date

Wealth of Data
Aside from scientists interested in conservation of genetics of crops & their wild relatives, few agricultural scientists see the value of their data to the biodiversity community Value in peer-reviewed publications, not data
publication Concern about losing control of their dataset
Biodiversity community has traditionally only paid attention to what is stored in museums or databanks

Land Managers, Climate Change Specialists Need
More than one-off collections of taxa Sampling biased by
collector, but not always apparent
Need measures over time of Presence and absence Diversity
Under varying conditions

Agricultural Research has Rich Data Heritage
Purposefully constructed hypotheses tested in Variety of (controlled) habitats
& (uncontrollable) abiotic conditions
Replicated experimental designs Examine effects of manipulation
of the environment on species behavior
Samples taken at uniform intervals over seasons, years

Integrated Pest Management Sets an economic
threshold for making decisions on strategies for maintaining pests at, or below a threshold of economic loss (economic injury level)
The choice of strategies can conserve Biodiversity Water, air, & soil quality money

Aphids - Pucerons - Afidos
Direct pests of plants Vectors of plant viruses Produce honeydew
Food source for ants, predators, & parasitoids
Molds Damage to crops depends on
when & in what numbers they appear in the field

Tracking Aphids at Elevations Above Ground Level (AGL)

aphids accumulate at or in inversions (temperatures are warmer than the air below)
Wind speed Below jet, aphids local In jet, had traveled
overnight from sources 240-400 km south from overwintering populations

Implications of Darwin Core for Agricultural Data
Simple Darwin Core Most agricultural
data fit rows/columns
Fields used only once
No minimum/ maximum data
Will include samples with 0 to multiple observations for a taxon
Challenges Human observations
(not preserved) thus not given an identifier
Asked to think about data in unaccustomed ways
Asked to document items usually noted once in a field notebook
![Page 19: Integrating the Monitoring of Agricultural Pests into Biodiversity Assessments](https://reader035.vdocuments.mx/reader035/viewer/2022062815/56812be7550346895d906633/html5/thumbnails/19.jpg)
Example of SimpleDarwinRecord
Easier to use Excel spreadsheet or create a database template to export to Excel
![Page 20: Integrating the Monitoring of Agricultural Pests into Biodiversity Assessments](https://reader035.vdocuments.mx/reader035/viewer/2022062815/56812be7550346895d906633/html5/thumbnails/20.jpg)
Challenges Mixture of
observations & vouchered specimens
Results buried in literature
Little or no metadata for raw data
Scientists have little incentive to go to extra trouble to share
![Page 21: Integrating the Monitoring of Agricultural Pests into Biodiversity Assessments](https://reader035.vdocuments.mx/reader035/viewer/2022062815/56812be7550346895d906633/html5/thumbnails/21.jpg)
Conclusions If we want to incorporate
agricultural datasets into our biodiversity assessments, we will need to work with these scientists to make it easy to provide their data in a format that is fit for use by the biodiversity community. Biocontrol in action!Biocontrol in action!

How do we do this? Jim Case provided in talk earlier today,
Bring groups together Provide introductory guides (documents) Provide links to resources Registry system Discussion forums bring users together
And engage the cooperation of journals to provide a home for data with its metadata
