Authorship of Italian medical literature on neuroendocrine neoplasms: any gender gap?
No full textPurpose: While males have dominated the physician lines over the last decades the recent female doctors' number increasing might progressively reduce this gender gap. This might be not fully true in the academic/research area. We aimed to analyze the gender distribution of first/senior Italian authors on neuroendocrine neoplasm papers published on peer reviewed journals. Methods: Publications from January 2019 to September 2023 were reviewed; only papers with first and/or senior Italian authors were included. First/senior author gender, type of article, co-authorship with foreign authors were the variable analyzed. Results: 742 papers with Italian first and/or senior authors were retrieved, 449 (60.5%) multicentric, 285 (38.4%) original articles. A female author was first and senior author in 386/742 (52%) and in 228/742 (31%) papers, respectively. 150 (20.2%) papers included foreign coauthors, being an Italian female researcher first author in 50 papers (33%), senior author in 28 (18.6%). The number of Italian female first/senior authors has been increasing over the years (22 in 2019, 113 in 2022; 16 in 2019, 62 in 2022, respectively). The first/senior female authors were mainly Oncologists/Endocrinologists/Pathologists rather than Gastroenterologists/Nuclear Medicine doctors/Surgeons/Radiologists. Conclusion: There has been an increase in the prevalence of female authorship of published research in the neuroendocrine setting over the last 5 years, which partially reflects the current distributions in this field, taking into account that several specialties with different gender distribution are involved. However, senior authorship continues to be primarily men. Efforts should be made to improve proportionate gender representation in both clinical and academic/research setting

Floristic changes along the topographical gradient in montane grassland in Monti Picentini (Campania, South-Western Italy)
No full textZonazione altitudinale della vegetazione di alcuni rilievi dell'Appennino meridionale e sue implicazioni fitostoriche
No full textCurrent methodological praxis in present day plant ecology and vegetation science, makes remarkably difficult to treat topics dealing with floristic changes along gradients, when qualitative aspects, based on biogeographical patterns are involved. Due to this, some outstanding “anomalies” in the altitudinal zonation of vegetation in southern Apennines and in the main islands, have traditionally been neglected or underestimated in their explanatory capacity for long-term vegetation processes. In this sense, patterns of floristic changes along topographical gradients observed in the Southern Italian ridges, from Monti Picentini (Campania) to Etna (Sicily) might be crucial for the interpretation of events and genesis of the plant cover of that part of peninsular Italy.
Here, the local ranges of some emblematic species are taken into account. Similarity in their sequences along local “catenas” with analogues in other regions of Southern Eurasia, are here used to infer modes of colonization and altitudinal stratification mirroring major events of Neogene climatic and paleogeographical changes.
In particular the patterns of altitudinal clustering of some taxa in Monte Etna, seems to be of major relevance for the detection of “fossil” zonations related to ancient environmental scenarios. The local behaviour of Pinus nigra s.l compared to its behaviour in the surrounding massifs and in other S-E European locations, suggests a pervasive persistence of Late-Miocene distribution patterns related to the connections with south and eastern Mediterranean landmasses of the emerging Italy of Late-Neogene
Floristic changes along the topographical gradient in montane grasslands in Monti Picentini (Campania, SW Italy)
No full textPopulations of xerotolerant species (Achnatherum calamagrostis, Stipa crassiculmis subsp. picentina, are scattered along a wide altitudinal gradient on slopes at mid- and high elevation in Monti Picentini, a subcoastal mesozoic limestone ridge in Tyrrhenian Southern Italy.
Their stands are widespread in grasslands of mostly secondary origin. At lower altitudes these grasslands replace former deciduous forest communities dominated by oaks or beech, while at higher altitudes they reach the summits, where they apparently merge into the remnants of the still partially grazed, zonal climatogenic, grasslands ranging above the local tree-line.
Nevertheless primary stands of these grasslands are to be found around the many clusters of highly dynamic sites of the montane and sub-alpine levels, scattered around screes and rocky outcrops of the prevalently dolomitic morphology of the slopes. This virtual continuity of non arboreal communities across more than 1000 metres of the local topographical gradient, where azonal, relic stands of Pinus nigra s.l. are transitional between the grasslands and the surrounding zonal broadleaved forest vegetation, stresses patterns of the coenological changes between Festuco-Brometea and Elyno-Seslerietea along the catena, which suggest fragmentary persistence of a paleozonation
