Parascon nichollsae Pilato & Lisi, 2004, n. sp.
No full textParascon nichollsae n. sp. (Fig. 2. A –D) Description of the holotype: Body length 220.0 µm, colorless, cuticle smooth without pores, eye spots absent. Buccopharyngeal apparatus of Parascon type (Fig. 2 A); buccal tube rigid without ventral lamina, pharyngeal tube rigid without spiral thickening; apophyses for the insertion of the stylet muscles shaped like flat ridges; their caudal processes (very thin and pointing laterally in the genus) not visible due to the orientation of the specimen. No cuticular droplike thickening present between buccal and pharyngeal tube. Stylet furcae very small, with very short branches, not swollen. Stylet supports present. Total length of the buccopharyngeal tube 20.8 µm; buccal tube 15.5 µm long (pbf = 74.5) and 1.5 µm wide (pt = 9.7). Pharyngeal bulb without apophyses and placoids (Fig. 2 A, C). Claws of Hypsibius type (Fig. 2 C); main branches with thin accessory points. On all legs the external claws have, as the other species of genera Parascon, Itaquascon and Astatumen, a slightly forked base. Due to the orientation, we were able to measure only the external claws of the first pair of legs (12.7 µm long: pt = 81.9), the external claws of the second pair of legs (13.4 µm long: pt = 86.5), and the internal claws of the second pair of legs (5.7 µm: pt = 36.8). Lunules and other cuticular thickenings on the legs absent. Differential diagnosis: Up to now only one species of genus Parascon is known: Parascon schusteri Pilato & Binda 1987 (Fig. 2 B) from Tanzania. The new species differs from it in the following features: shorter pharyngeal tube length in relation to the total length of the buccopharyngeal tube (see Fig. 2 and the values of the pbf index in table 1), shorter claws with lower values of the pt index (table 1).

La filiera corta per il consolidamento del mercato dei prodotti biologici
No full textIn the last years the economic and environmental sustainability of modern agriculture has been often challenged. It is affected more and more also by the several market crisis and the productive processes with a significant environmental burden.
The organic agriculture might be a suitable solution to change course on these concerns. In the last few years its market has continued to grow also thanks to the introduction of new marketing strategies very often linked to the concept of short supply chain.
The aim of this note is the analysis of the main characteristics of the organic food market, focusing on the factors that can lead to the enhancement of this agricultural sector.
For this purpose the constraints and the potentials for the " short supply chain" concept have been highlighted, taking into account the effects generated from its widespread application in the distribution phase of the biological food

Doryphoribius solidunguis Lisi, 2011, sp. nov.
No full text<i>Doryphoribius solidunguis</i> sp. nov. <p>(Fig. 5)</p> <p> <b>Material examined.</b> Holotype (slide number 3796), 37 paratypes and 12 exuviae with eggs (slide numbers 3785- 3796, 4179, 4180) mounted in polyvinyl lactophenol; Bali: Tampaksring, from a moss sample (data available from Pilato & Binda, 1990).</p> <p> <b>Specific diagnosis.</b> [Eye spots present*], very evident reticulate sculpture on dorsal and lateral cuticle forming mesh that was quite irregular in shape and size, delimited by ridges of various width (some very wide); the ridges were often rather protruding, only sometimes forming tubercles at crossings. Anterior sides of the first three pair of legs and posterior side of the fourth pair of legs, swollen; legs smooth. Bucco-pharyngeal apparatus of the <i>Doryphoribius</i> type; peribuccal papulae present, some of which were divided. Two pairs of dorsal teeth in the buccal cavity, difficult to see, along the anterior margins of the stylet sheaths. Two macroplacoids and no microplacoid or septulum in the pharyngeal bulb. Claws of the <i>Isohypsibius</i> type, large and stout, with very small accessory points on the main branches; external claws with wide basal portion enlarged at the very base; internal claws with smaller basal portion; evident smooth lunules present. A cuticular bar partially divided into dots was present beside the base of the internal claws of the first three pairs of legs. Smooth eggs laid into the exuvium.</p> <p>[*] = Not visible after mounting in polyvinyl lactophenol.</p> <p> <b>Description of the holotype.</b> Unfortunately the mounting media had caused contraction to a greater of lesser extent in many of the specimens. I have therefore designated as the holotype a specimen that best shows the most important characters of the species.</p> <p> It was not possible to correctly measure body length (probably about 380 µm) but in Table 4 the correct measurements are provided of a paratype; eye spots no longer visible; dorsal and lateral cuticle ornamented with ridges, often protruding and wide (especially those of the medial-dorsal cuticle), which formed a reticular design with mesh of various shape and size (Fig. 5 A in a paratype); the average size of the mesh increased from the lateral to the dorsal cuticle and from anterior to the posterior portion of the body, reaching the maximum between the third and the fourth pairs of legs (largest mesh about 7.3 µm; <i>pt</i> index 16.7) and decreased more posteriorly. On some crossings a tubercle could be seen, on others it was clearly absent, while in other cases the protruding ridges made it difficult to discern whether a tubercle was present or not. Due to the orientation of the specimen in the slide, the swollen portions (anterior for the first three pairs, posterior for the fourth pair of legs) were not visible but were in the paratypes. Cuticle of the legs smooth.</p> <p> Holotype Slide N. 3796 Smallest paratype Slide N. 3796 Largest paratype Slide N. 3796 Characters µm pt % bo-le µm pt % bo-le µm pt % bo-le III ex. claws 25.8 59.2???? 21.8? 52.9? 6.0? III int. claws 21.8 50.0??????? Bucco-pharyngeal apparatus of the <i>Doryphoribius</i> type (Fig. 5 B); peribuccal papulae present, some of which were divided; buccal armature consisted of only two pairs of dorsal teeth (Fig. 5 C, arrow), difficult to see, along the anterior margin of the stylet sheaths. Buccal tube 43.6 µm long and 5.9 µm wide (<i>pt</i> = 13.5), stylet supports inserted on the buccal tube at 70.0 % of its length (<i>pt</i> = 70.0); ventral lamina 25.4 µm long (<i>pt</i> = 58.3). Pharyngeal bulb could not be measured, with apophyses and two macroplacoids; no microplacoid or septulum present; placoid row 15.2 µm long (<i>pt</i> = 34.9), first macroplacoid slightly constricted in the middle, 8.5 µm long (<i>pt</i> = 19.5), second one 4.5 µm (<i>pt</i> = 10.3).</p> <p> Claws of the <i>Isohypsibius</i> type (Fig. 5D –G), slightly different in shape and size on each leg, large and stout, with poorly developed accessory points on the main branches; external claws with wide basal portion enlarged at the very base, internal with smaller basal portion; smooth lunules present, well developed under both the internal and external claws of the first three pairs of legs (Fig. 5 F, arrow). A cuticular bar partially divided into dots was present beside the base of the internal claws of the first three pairs of legs (Fig. 5 G, arrow). The measurements of the claws and the other metric characters of the holotype are reported in Table 4.</p> <p> <b>Remarks.</b> The paratypes showed the same, both qualitative and metric, characters of the holotype. The measurements of some structures are reported in Table 4. Smooth eggs (4–7) laid into the exuvium.</p> <p> <b>Etymology.</b> The name of the species refers to the stout claws: “ <i>solidus</i> ” = “stout”, “ <i>unguis</i> ” = “claw”.</p> <p> <b>Type depositories.</b> The type material is deposited in the Binda and Pilato collection (Museum of the Department of Animal Biology “Marcello La Greca”, University of Catania).</p> <p> <b>Differential diagnosis.</b> <i>Doryphoribius solidunguis</i> <b>sp. nov.</b> differed from <i>D. flavus</i> by having cuticular sculpture with smaller mesh (Table 5); the reticular design appeared more irregular due to the more variable width of the ridges, which were also more protruding and formed tubercles at some crossings. The legs had no reticular ornamentation. The new species had only two pairs of dorso-lateral teeth in the buccal cavity; stouter claws (Figs. 1 C– D, 2E and 5D–G); more evident lunules of the inner claws (Figs. 2 F and 5F); and a cuticular bar on the first three pairs of legs.</p> <p> <i>D. solidunguis</i> <b>sp. nov.</b> differed from <i>D. polynettae</i> above all in lacking cuticular sculpture on the ventral surface; by having a far more obvious dorsal cuticular sculpture with some tubercles present at the crossing of the mesh; pores nor roughness on the cuticle, absent; swollen portions of the legs; only two pairs of teeth in the oral cavity; wider buccal tube, stouter claws; and cuticular bars on the legs.</p> <p> <i>Doryphoribius solidunguis</i> <b>sp. nov.</b> differed from <i>D. amazzonicus</i> <b>sp. nov.</b> by having the reticulate cuticular sculpture formed by thicker, more protruding ridges forming tubercles only at some crossing of the mesh. The largest mesh had higher <i>pt</i> index values (Table 5). <i>D. solidunguis</i> <b>sp. nov.</b> also had slightly shorter buccal tube with respect to the body length (Table 5); two pairs of teeth in the buccal cavity (not visible in <i>D. amazzonicus</i>); stouter claws which were also longer with respect to the buccal tube length (compare Table 2 with Table 4). It had more evident lunules of the inner claws and a cuticular bar at the base of the inner claws on the first three pairs of legs, which is absent in <i>D. amazzonicus.</i></p> <p> <i>D. solidunguis</i> <b>sp. nov.</b> differed from <i>D. bindae</i> <b>sp. nov.</b> by having a more evident reticulate cuticular design with larger mesh (Table 5) formed by far wider and more protruding ridges; tubercles present only at some crossing of the ridges; legs unsculptured; two pairs of teeth in the buccal cavity instead of only one; longer and stouter claws (Table 5, and compare Table 3 with Table 4, Figs. 4D –F and 5D–G); more evident lunules of the inner claws, and a cuticular bar on the first three pairs of legs, absent in <i>D. bindae</i> <b>sp. nov.</b></p> <p> <i>D. solidunguis</i> <b>sp. nov.</b> differed from <i>D. quadrituberculatus</i> above all by lacking dorsal gibbosities; mesh comprising ridges with tubercles at some of the crossings; swollen portions of the legs; peribuccal papulae; only two pair of dorsal teeth in the oral cavity; lunules at the base of the claws; and cuticular bars on the legs.</p> <p> <i>D. solidunguis</i> <b>sp. nov.</b> differed from <i>D. smokiensis</i> by having eyes; different type of cuticular sculpture; swollen portions of the legs; only two pairs of dorsal teeth in the oral cavity; far narrower buccal tube; lunules at the claw base; cuticular bars on the legs; and other minor details.</p> <p> mer paratype of <i>Doryphoribius citrinus</i>; the values in brackets are from another paratype of the same body size), the paratype</p> <p> of <i>Doryphoribius amazzonicus</i> <b>sp. nov.</b>, the holotype of <i>D. bindae</i> <b>sp. nov.</b> and a paratype of <i>D. solidunguis</i> <b>sp. nov.</b>; “Styl.</p> <p>supp. insert.” indicates the stylet supports insertion point on the buccal tube; “% bo-le” indicates the percentage ratio with</p> <p>respect to the body length (calculated for the buccal tube length, the placoid row, the claws and the largest mesh).</p> <p> <i>D. flavus D. amazzonicus</i> <b>sp. nov.</b> <i>D. bindae</i> <b>sp. nov.</b> <i>D. solidunguis</i> <b>sp. nov.</b> slide N. 1200 slide N. 4828 slide N. 3609 slide N. 3796</p> <p>Characters µm pt % bo-le µm pt % bo-le µm pt % bo-le µm pt % bo-le</p> <p>Body length 404 - - 241.2 - - 327.6 - - 361.3 - -</p> <p>Buccal tube length 46.7 - 11.6 33.2 13.8 - 36.7 - 11.2 41.2 - 11.4</p>Published as part of <i>Lisi, Oscar, 2011, Remarks on Doryphoribius flavus (Iharos, 1966), and description of three new species (Tardigrada, Hypsibiidae), pp. 17-32 in Zootaxa 2834</i> on pages 28-31, DOI: <a href="http://zenodo.org/record/277335">10.5281/zenodo.277335</a>
Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
