A new species, , is described and illustrated based on collections from the Majella Mountains in Central Apennine, Italy. It is morphologically similar to Boiss., but can be distinguished by green leaves, the basal ones adaxially lightly scabrous or sparsely hairy, longer ligules particularly in the upper leaves, panicles denser with primary branches sub-erect to erect, glumes with broader scarious margin, more acute glumes and lemmas, lemmas and paleas longer, rachilla hairy, calluses usually with a crown of hairs or shortly webbed, caryopses longer. A distribution map of the species is also presented.

European mountain systems have played a crucial role in shaping the distribution of species and of their genetic diversity during the Quaternary climatic changes, with the establishment of allopatric patterns across main mountain ranges. Here we investigated the evolutionary history of flea beetles of the species-group showing an uncommon disjunct biogeographic pattern across the Apennine and the Pyrenees. We applied a multilocus molecular approach and multispecies coalescent models to establish a phylogenetic and systematic framework for this morphologically homogeneous species-group and to estimate the time of main cladogenetic events underlying the origin of the Apennine-Pyrenees pattern.

Interspecific interactions among species of the same guild play a critical role in shaping their realized niches, and their understanding may disclose mechanisms of coexistence. Investigating interactions among apex predators is of ecological and management interest, especially in human-dominated landscapes where type and intensity of their interspecific competition may be affected by human interference. During 2005-2010, we investigated, by means of GPS-telemetry, interactions between brown bears ( = 19) and wolves ( = 7) in a long-established national park in the central Apennines, Italy, where bears and wolves have always coexisted close to humans.

Permanent and temporary ponds are considered peculiar ecosystems which provide important ecosystem functions, services, supporting biodiversity on small and large scales. Pond's conservation status is globally critical. Moreover, their ecological functioning and conservation status is frequently overlooked, because of the habitat small size, their seasonal occurrence and their unique appearance.
