FINAL THOUGHTS. I'm still going to use GenAI, but I'm going to ask why it gives me the responses that it does more often. GenAI is a roleplayer, at times it appeared chipper, sycophantic, & remorseful (without ever directly saying it shouldn't have made πŸ’© up).

I dug deeper. Since #GenAI essentially "roleplays" responses I asked it about potential reputational harm if I used this false information. I agree with its responses.

I checked to make sure that both ChatGPT and I were using the same definition of terms. then asked WHY I were given dubious claims.

It turns out that real elements were blended with "illustrative" (but false) details.

I started by asking for real examples of a farmer that uses technology to manage insects, then refined my question to specify an Australian example. I given the name of a real farmer, a bold claim of a 50%reduction in #insecticide use. Without references.

I've been exploring how to use #GenerativeAI to create engaging narratives. Check out this thread to read about my discussion with ChatGPT about why it gave me misleading "facts"

The results were fascinating.
I'm going to start asking why I was given particular responses more often now.

While "mop-top" refers to a distinct deformation of the leaves, sometimes associated with bright yellow v-shaped marks, foliar symptoms are not always present. More often inside the tubers have dark discolored rings. It can be mistaken for other potato diseases. - buff.ly/bxW2jXL

Potato mop-top virus ( #PMTV ) has been detected in Tasmania for the 1st time. To the best of our knowledge, this virus is not widespread in the region yet, but it is crucial to be vigilant for this disease. - buff.ly/A7ovJ8g

Did you know our Newnham campus is home to an orchard that dates back to the 1800s?
A rehabilitation of the orchard is underway.
TIA’s tree crop physiologist Leticia Reis and entomologist Justin Cappadonna hosted a workshop to teach attendees how to prune apple trees and keep an orchard healthy. πŸ‘

A huge thank you goes out to Leticia Reis, the Tasmanian Institute of Agriculture team, & the University of Tasmania Community Gardens staff for helping this event run so well.

I'm looking forward to the upcoming revitalization events later this year.

Are you a berry grower in Tasmania? πŸ“
Our entomologists are advising berry growers in the state to be aware of an emerging pest, the Bronze Leaf Beetle.
Bronze Leaf Beetles chew on leaves, flowers and fruits, causing poor quality and reduced yields.

Recently, I was invited to speak with the Australian Plants Society Tasmania. We discussed #pollinator #conservation on #farms, & the importance of "refuges" amongst monoculture (single crop) fields. It was great to meet so many engaged & passionate gardeners. - @tia.utas.edu.au @utas.edu.au

From wildlands to farmlands, we need to put functional roles front & centre.
Insect functional diversity supports pollination, pest control, nutrient cycling, & more.

Let’s design systemsβ€”conservation & agriculturalβ€”that work with insects, not without them. #Agroecology #InsectConservation

We can’t afford to forget insects when managing landβ€”especially not on farms.

Across >5000 studies, diversified farming practices increased functional diversity and ecosystem servicesβ€”without reducing yields.

Drawing on 20 years of community data, Rodrigues et al. found that functional trait compositionβ€”not just the number of speciesβ€”is key to predicting how ecosystems respond to change.

It’s a reminder: biodiversity is about what organisms do.

Functional diversity isn’t just a buzzwordβ€”it’s the engine of ecosystem resilience.

A new study shows that the stability of ecological communities depends not just on species richness, but what functional roles those species play.

I didn't intend for things to get so dirty, but when I visited the University of Tasmania gardens to discuss a partnership with the Tasmanian Institute of Agriculture (STAY TUNED) we ended up talking about their amazing #composting machine in the heart of campus.
