Geophilomorph centipedes in the Mediterranean region: revisiting taxonomy opens new evolutionary vistas
No full textGeophilomorph centipedes (Geophilomorpha) are represented in the Mediterranean region by almost
200 species, 77 % of which are exclusive. Taxonomy and nomenclature are still inadequate, but recent
investigations are contributing to a better understanding of the evolutionary differentiation of this group
in the region. Since 2000, identity has been clarified for ca. 40 nominal taxa, and unexpected evidence
has emerged for the existence of three well-distinct lineages that had remained unrecognised before. Of
these, Eurygeophilus has evolved an unusually stout body and needle-like forcipules, and the vicariant
pattern of its two species is peculiar in encompassing both the Pyrenees and the Corsica-Sardinia
microplate; Diphyonyx has evolved unusually pincer-like leg claws, convergent to those originated
independently in two different unrelated geophilomorph lineages; Stenotaenia has maintained a very
uniform gross morphology, while differentiating widely in body size and number of trunk segments. The
fauna of the Mediterranean region is representative of most major lineages of the Geophilomorpha, and
the almost exclusive Dignathodontidae exhibit a remarkable morpho-ecological radiation in the region.
Essential to a better understanding of the regional evolutionary history of these centipedes will be
assessing the actual species diversity within many of the already recognised lineages, and reviewing in
a phylogenetic perspective the nominal taxa currently referred to the composite genera Geophilus and
Schendyla

The road towards sustainability: projects of renewal enhancement of green areas in the city: the Senigallia case study.
No full textIn 2010 the municipality of Senigallia, located in Marche region (Italy),requested to thethe Department of Agricultural Sciences together with the Department of TerritorialPlanning of the Alma Mater Studiorum of Bologna and in collaboration with four architects, two agronomists and communaltechnicians to draft the Green Masterplan (GM) of the city. Aim of the request was to promote a neat, homogeneous and sustainable development of the territory and improve the quality of life and the wellness of its inhabitants. It also targeted the reduction of the CO2, produced by the extension of the highway, that divided urban and rural landscape. In order to attain these objectives, the working group proposes to increase both the amount and the value of the green areas, and alsotheir level of interconnection.Specific guidelines for future planning and projects are proposed. The GM was approved and, since 2010, many projects have been proposed and realized during last years. The projects proposed and the ones that has been realized tried to create a big greenway, able to connect the northern zone of the town to the southern zone of the town, by the creation of new green areas, urban forests, tree-lines boulevards and green roundabouts. The article aim at describing these projects, which tried to enhance and protect the green areas of the city as a system. The approach that conceives green areas as residual elements, essentially serving as a décor, is surmountedby bringing back their leading role that inhabitants, ecological balance, and sustainability of our living models attach to it. The green presence is here considered as a new infrastructure which needs to be carefully planned, subjected to regulations and efficiently managed, used as a regulatory instrument for the territory, preserved and constantly maintained in good conditio
Arthropod segmentation and tagmosis
No full textAccording to a well-consolidated tradition, the body of arthropods is described in terms of segments and tagmata. Even the oldest names for these animals, Aristotle's εντομα [entoma, internally (sub)divided] and Linnaeus' Latin equivalent Insecta, now restricted to one of the major arthropod subgroups, already referred to the modular organization of the body. In the idealistic perspective of the past, this trait, more than the presence of articulated appendages to which the current name of arthropods refers, was considered the defining attribute for the body plan of these animals
Geophilus linearis C.L. Koch, 1835 and Geophilus sorrentinus Attems, 1903 (currently Stenotaenia linearis and S. sorrentina; Chilopoda): proposed conservation of the specific names
No full textThe purpose of this application, under Article 23.9.3 of the Code, is to
conserve the specific names linearis C.L. Koch, 1835 and sorrentinus Attems, 1903,
both originally published in Geophilus Leach, 1814, for two widespread European
species of geophilomorph centipedes currently referred to the genus Stenotaenia
C.L. Koch, 1847 of which Geophilus linearis C.L. Koch, 1835 is the type species.
Stenotaenia linearis (C.L. Koch, 1835), which is currently in universal and common
use, is threatened by the long forgotten subjective synonym Geophilus simplex
Gervais, 1835 because of a first-reviser action by Gervais (1837) which has been
practically disregarded since 1918. Stenotaenia sorrentina (Attems, 1903) is threatened
by its putative, subjective synonymy with Geophilus forficularius Fanzago, 1881,
a name never used as valid since the year of publication
