Hi Oliver, we have data from 24 hares tagged with gps collars and followed for 6 months in agricultural area of northern Italy (orchards, vineyards, maize wheat). we know the products used in the crops and we have samples of   bone muscle, liver faeces and so on. I've never used this data. I must ask the permission to use them to the company that financed the research.

Small mammals are more useful for this kind of research because a single field can include the home range of the animal. Ungulates have larger home ranges and a field can be used occasionally in the home range. I mean, that what can affect ungulates surely affect small mammals. Do you have an interest in a particular product?

Hello Dear

It is more a general interest.

i also thought about hares, as we were also involved in similar projects. However, I wondered if there IS anything on larger mammals (esp. more recently)? And I wondered if there are some accumulations?

It looks like there is no interest (!!!) by companies or governments to investigate these effects on that animals (hard to do, afraid of finding some effects ???)

G'day Oliver,

There has been a few studies about residue analysis following baiting operations in large mammals, particularly feral pigs. This is mainly to assess secondary poisoning risk or to determine safe withholding periods prior to harvest. I know this is probably left of field of your request, but some of the methods etc. are of interest. Residues are typically low levels, but still detectable, with direct consumption of bait material containing large amounts of toxin. Looking for environmental/agricultural pesticides would probably be difficult and obviously would have to have a good idea about what toxins you are looking for, and metabolism, fate etc.  I'm happy to send you the link to these if they are of interest

cheers

Matt
