During the symposium there will be the presentation of the first results of Sunbear (Helarctos malayanus) conservation project that UAGRA is following as partner of Istituto Oikos, WCS and Fondation Segré.
During camera trapping field campaing several Sunbears and other endangered species have been captured underling how important is to preserve tropical forest habitat.
This is the first study that confirms the invasiveness of the Pallas’s squirrel also in terms of capability to compete with native species. UAGRA shows how the Palla’s squirrel in Italy competes with the Eurasian red squirrel for space and food resources. Read more here.
Here what Damiano (Preatoni) thinks of the recent book on camera trapping by Francesco Rovero and Fridolin Zimmermann
The book everyone working with camera traps should have. A detailed and complete “hands-on” approach on camera trapping, with applied examples on almost every aspect of using camera traps, from planning (camera choice, deployment, etc.) to data colleciton and analysis. Strong of several decades of photographic trapping experience, the Authors offer to the reader their first-hand experience.
During this week UAGRA is hosting the Master in Management and Conservation of Environment and Fauna, both lectures and fieldwork.
Next week UAGRA staff will be with master’s students at Adamello-Brenta Nature Park
You can find more information on the master here and here.
Current and future conifer seed production in the Alps: testing weather factors as cues behind masting
Forest resilience to climate change?
Temporal patterns of masting in conifer species are intriguing phenomena that have cascading effects on different trophic levels in ecosystems. Many studies suggest that meteorological cues (changes in temperature and precipitation) affect variation in seed-crop size over years. We monitored cone crops of six conifer species in the Italian Alps (1999–2013) and analysed which seasonal weather factors affected annual variation in cone production at forest community level. Larch, Norway spruce and silver fir showed masting while temporal patterns in Pinus sp. were less pronounced. We found limited support for the temperature difference model proposed by Kelly et al. Both seasonal (mainly spring and summer) temperatures and precipitations of 1 and 2 years prior to seed maturation affected cone-crop size, with no significant effect of previous year’s cone crop. Next, we estimated future forest cone production until 2100, applying climate projection (using RCP 8.5 scenario) to the weather model that best predicted variation in measured cone crops. We found no evidence of long-term changes in average cone production over the twenty-first century, despite increase in average temperature and decrease in precipitation. The amplitude of predicted annual fluctuations in cone production varies over time, depending on study area. The opposite signs of temperature effects 1 and 2 years prior to seed set show that temperature differences are indeed a relevant cue. Hence, predicted patterns of masting followed by 1 or more years of poor-medium cone production suggest a high degree of resilience of alpine conifer forests under global warming scenario.
