The Dendrochronology Laboratory at the University of Turin
is part of the Department of Agronomy, Silviculture and Land Management. This
is a satellite campus that is located on the outskirts of Turin. They focus on
dendroecology and forest management in anthropogenically altered landscapes.
They also have a specialty area in fire ecology and use wood anatomy in many of
their studies.

The lab had the standard wall display of charismatic
specimens which I was intrigued by, although this is the only collection that I
have ever seen that includes the head of a wild boar which apparently was a
problem on one of their sampling sites.
This core shows the suppressions from larch budmoth (Zeiraphera diniana) which
is a common defoliating insect in Larix trees throughout Europe. It has a very
regular eight year cycle that changes strength through time.
Dr. Renzo Motta was my main contact for all of my travels in
Northern Italy and was a gracious host.
I got to enjoy one of the best meals that I had during my European
travels in Pavia with his family at a small restaurant in the old city. I had
contacted Dr. Motta about his mast (tree seeding) data sets back in 2000 during
my PhD dissertation. I was happy to hear that he is looking into using this
dataset that they collected and that Piovesan had published on masting in beech
(Fagus) trees (see the previous post). Dr. Motta has done a lot of work
examining ungulate effects on tree growth (Motta 1996). I appreciated his work
with coarse woody debris in forests (Motta et al. 2006b) which is something that
we have examined in my lab through Ross Alexander’s work on his masters thesis.
During our tour of the Western Italian Alps, Renzo pointed out a stand of trees
that was left on the landscape because the local villagers knew that it
protected them from snow avalanches. He has done some research on protective
forests such as this (Motta and Haudemand 2001) and examined other human land
use effects (Motta and Nola 2001, Motta et al. 2006b).
Dr. Giovanni Bovio has done some dendrochronological work
with Dr. Motta and the others in the lab and has published work on land zoning
and fire history (Bovio and Camia 1997) and the effect of sylviculture on
forest fires (Bovio 2011).
Dr. Raffaella Marzano focuses on fire ecology in the
wildland-urban interface (Marzano et al. 2008) and the establishment of
seedlings after forest fires (Marzano et al. 2013). I got to see a poster of
some repeat photography that Dr. Marzano took after a fire that showed the growth
of herbs and the establishment of seedlings on plots with different forest
management techniques. I hoped that we would be able to visit this site in the
Western Italian Alps during our field tour, but we did not have the time to get
to this site.
Dr. Davide Ascoli specializes in fire ecology and has
actually examined fire scars in two angiosperm genera (Populus and Betula,
Ascoli and Bovio 2010). During my European travels, I was presenting on three
research projects, one of which was the potential of scarring from fire in 15
angiosperms species. So it was exciting to see Dr. Ascoli’s work that examined
multiply scarred angiosperms. Much of Dr. Ascoli’s other work includes adaptive
management and use of prescribed burning in Italy (Ascoli et al. 2009, Ascoli
and Bovio 2013, and Ascoli et al. 2013).
Dr. Giorgio Vacchiano specialized in forest ecology with a
main focus on modelling (Vacchiano et al. 2008) and has also conducted some
drought stress analysis in Scots pine (Vacchiano et al. 2012). He also has some recent publications simulating forest encroachment (Vacchiano et al. 2014a) and examining the effect of soils on Scots pine recovery after fire (Vacciano et al. 2014b). Dr. Vacchiano
was also very helpful in planning my day tour to the Western Italian Alps.
I spent a wonderful evening with Renzo and his colleagues.
We ate some true Italian pizza (the best in the world) and were treated to
gelato at Groms afterwards that might just be the best gelato in the world.
They gave me a great tour of the Turin in the evening where I got to hear about
the history of the city and also some personal views of growing up in this
city. I was interested in hearing about academic process in Italy. The norm is
to progress through all degrees (BS, MS, and PhD) at the same institution and
then to teach there when you are done. From my travels I found that in Italy,
Switzerland, and the Czech Republic the people are much more connected to their
community (and home) and they don’t tend to move nearly as much as the United
States norm. Also, all three countries have a limited number of academic
institutions where one can get a job which means that professorships are
limited within their countries. I forget the specific numbers, but if a PhD
researcher wanted to stay in Italy, they could only apply to 5-10 potential
institutions for a job compared to the thousands that are available in the US. Germany
had many more institutions that one could choose from and had more of a
migratory population.
