Introduction
My main research interest is applying GIS in wildlife management, forestry and ecology. I have been teaching FOSS GIS since 2004 at professional courses and at universities of Trento, Varese and Milano. I developed free tutorials for the self learning of GRASS and QGIS. I am also interested in the effect of (eco) tourism on large carnivore conservation. I am guest researcher at the University of Trento, Forest Ecology Lab.

Migratory birds need to stop along their route to rest and feed at so called stopover sites. “Bolle di Magadino” is a protected wetland located near lake Maggiore (CH), an internationally recognized nesting and stop-over site for birds. The waters of Lake Maggiore are important resources for multiple usages, and are artificially regulated through a...

In the last decades the Alpine landscape has dramatically changed due to social and economic factors. The most visible impact has been the reduction of the population for mid and high altitude villages and the shrinking of the part of the land used for agriculture and grazing, with a progressive reduction of pastures and meadows and the expansion o...

Wildlife-vehicle collisions cause damages and loss for people and animals alike and are a reason of human wildlife conflict. Collisions are considered a consequence of the landscape fragmentation which is also a major cause of biodiversity loss worldwide. In Europe the most of the recorded accidents involves ungulates, and in Trentino (N Italy) a s...

Windstorms are a major disturbance factor for European forests. The 2018 Vaia storm, felled large volumes of timber in Italy causing serious ecological and financial losses. Remote sensing is fundamental for primary assessment of damages and post-emergency phase. An explicit estimation of the timber loss caused by Vaia using satellite remote sensin...

Occupancy models estimate presence and detection probability of species of interest of which they provide useful information and also contribute to decision making. In this proof-of-concept, we propose an approach to demonstrate the applicability of occupancy models in insect monitoring having as targets the spittlebug Philaenus spumarius, the m...

Recent events related to the measures taken to control the spread of the Coronavirus (SARS-CoV-2) reduced human mobility (i.e. anthropause), potentially opening connectivity opportunities for wildlife populations. In the Italian Alps, brown bears have recovered after reintroduction within a complex anthropogenic matrix, but failed to establish a me...

Land use changes in the Alps over the last few decades have been characterised by a significant increase in forest coverage as a result of the abandonment of marginal agricultural sites. Natural afforestation and species protection laws affected the ecosystem, and therefore the services provided by the mountain environment, including landscape stru...

Rub trees are specific trees that bears mark with their scent to communicate their presence to possible partners or rivals. Adult males have been observed more frequently performing this behaviour especially during the mating season. Rub trees are recognizable from the other trees of the surrounding environment due to being larger or of a different...

Accurate estimates of seed production are central for understanding mast seeding mechanisms at tree and forest scales, and for designing sustainable management strategies. As trees are long-lived organisms, a long-term perspective is required to understand how reproduction acts during the life cycle of a tree. However, long-term series of seed prod...

The variation of species diversity over space and time has been widely recognised as a key challenge in ecology. However, measuring species diversity over large areas might be difficult for logistic reasons related to both time and cost savings for sampling, as well as accessibility of remote ecosystems.

Accurate estimates of canopy cover (CC) are central for a wide range of forestry studies. As direct measurements are impractical, indirect optical methods have often been used to estimate CC from the complement of gap fraction measurements obtained with restricted-view sensors. In this short note we evaluated the influence of the image pixel resolu...

Humans profoundly affect animal distributions by directly competing for space, not only transforming, but actively using their habitat. Anthropogenic disturbance is usually measured via structural proxies such as infrastructure and land use that overlook the impact of human presence, or functional disturbance. In this study, we propose a methodolog...

The French Alps is an important area for several species of crayfish; some species are native in this region and several were introduced by humans. The present study aimed at modelling the distributions of these two categories of species and find the significant environmental variables to explain these distributions. Field sampling was performed in...

In recent decades the growing interest in forested areas has led to a higher level of appreciation and consideration regarding the various benefits and services provided by forests. Despite this, when it comes to acknowledging their economic value and their capacity to produce income, the production of timber seems to be the main or even the only f...

Accurate and frequently updated tree volume estimates are required for poplar plantations, which are characterized by fast growth rate and short rotation. In this study, we tested the potential of terrestrial laser scanning (TLS) as a reliable method for developing nondestructive tree volume allometries in poplar plantations. The trial was conducte...

“BugMap” is a citizen science mobile application that provides a platform for amateur and expert scientists to report sightings of two invasive insect pests, the tiger mosquito Aedes albopictus Skuse (Diptera: Culicidae) and the brown marmorated stink bug, Halyomorpha halys Stål (Hemiptera: Pentatomidae). The latter is a notorious pest of fruit tre...

Bird migration is a long studied phenomenon that involves animals moving back and forth from wintering sites and to reproductive grounds. Several studies have focused on identifying the timing, physiology and evolution of migration, but a spatial approach to understand the migratory routes is still an open challenge.

Trentino is an Italian alpine region (about 6200 km²) with a forest coverage exceeding 60% of its whole surface. In the past, forest landscape has changed dramatically, especially in periods of forest over-exploitation.

Heritage maps represent fundamental information for the study of the evolution of a region, especially in terms of landscape and ecologic features. Historical maps present two kinds of hurdle before they can be used in a modern GIS: they must be geometrically corrected to correspond to the datum in use and they must be classified to exploit the inf...

CONCLUSIONS • Rubbing was significantly more performed by adult males with a peak during the breeding season. • Adult males used a greater variety of positions to mark the trees. • Rubbing occurred also during the non-breeding season, but with much less intensity. • Investigation of rub trees was performed by bears of all ages and sexes throughout...

The monitoring of natural hazards is of extreme importance in the areas of Italy where there are high hydrogeological and avalanche risks. Despite the fact that records of past events are sometimes available, some of their data are often incomplete and show that the monitoring and mapping of these phenomena are never enough to avoid damage. We pres...

Large-bodied mammals are a rich and diversified faunal group in tropical rainforests. However, knowledge on community size and composition, and on species’ distribution and ecology remains often scant and inadequate against their chronic status of threats.

In Italy, the reintroduction of the brown bear (Ursus arctos) has created conflicts with people because bears may damage livestock, crops, or honey farms. These damages—and their financial costs—are sometimes used as an argument by those who oppose the presence of this carnivore. Despite such damages, bears can provide economic benefits, such as at...

The behaviour of rubbing on trees by bears is an action whereby the animal stands on its back limb and scratches itself on the bark, sometimes leaving visible marks with its claws or teeth. The trees chosen for rubbing are usually the same over time, are used by different individuals and can be usually recognizable from the surrounding environment...

The behaviour of marking trees by the brown bear occurs throughout the range of presence of the species.
