In the years 2008-2012 we studied the nest-site characteristics of the Black Woodpeckers Dryocopus martius in the Varese province, in 3 study-areas in north-western Lombardy. The Black Woodpecker is a recent immigrant in our study area and in the surrounding pre-Alps; it selects wide-diameter trunk of mainly broadleaf trees, and the forest structure near the nest is significantly different from that of random spots within 500 m from the nest, with less dense trees of greater Diameter at Breast Height. We monitored 21 nesting events, of which 18 were successful and fledged 42 young, while 3 were unsuccessful; the overall fledging rate is 2,33 young/pair. The Black Woodpecker may be considered a habitat specialist for the nest site and habitat generalist in the home-range, with some territories very close to busy paved road and urbanized areas. From the original mountain sector, the Black Woodpecker expanded its range to the lower hill and, and, further south towards the plain, through the ecological corridor of the forests adjoining Lake Maggiore and the Ticino river.

The study was conducted in Chakrashila Wildlife Sanctuary of western Assam to explore diversity and habitat preference of odonata (both dragonflies and damseldly) from April 2018 to March 2019. During study period we recorded total 57 species of odonate from 39 genera and 8 families out of which, dragonfly (Anisoptera) represented by 37 species and damselfly (Zygoptera) represented by 20 species. Suborder Zygoptera were represented by the families Chlorocyphidae, Coenagrionidae, Platycnemididae, Euphaeidae, Calopterygidae and suborder Anisoptera by the Aeshnidae, Gomphidae and Libellulidae. Libellulidae was the largest family with 29 species, while Chlorocyphidae and Euphaeidae represent only single species. Among the five habitats highest species were recorded from wetland (63%) and lowest from dense forest (41%) while 20 species were recognized as habitat specialist and 7 species were habitat generalist.

Dirofilariosis is an emerging mosquito-borne veterinary and medical problem in the Northern hemisphere. The ecological investigation of 56 canine dirofilariosis cases in new endemic locations was performed in Szeged, Hungary. The aim was to analyse the influence of the spatial patterns of dog abundance and the potential mosquito breeding habitats on the spatial occurrence patterns of dirofilariosis in the city of Szeged. The limnoecological characterisation was based on the fluvial habitat classification of Amoros of natural water bodies; the built environment was evaluated using the UrbanisationScore urbanisation intensity measuring software. Dirofilaria immitis accounted for 51% and D. repens for 34.3% of the dirofilariosis cases, and in 20% of the cases only the Knott’s test was positive. It was concluded that most of the cases were related to locations with a medium to high urbanisation index, although the proximity of mosquito-bearing waters also played an important role in the observed spatial infection patterns. We found that the distance from potential mosquito habitats and the urbanisation intensity determine the abundance of dirofilariosis in urban environments.
