Coprinus Idae Uljé (Coprinaceae, Agaricales) found in Spain
No full textA new record of Coprinus idae Uljé, this time collected from Spain, is briefly described, and some taxonomic and ecologic observations are made. Up to now, this species has been reported from the Netherlands, only twice from the type-locality
Macropsis idae Emelyanov 1964
No full text15. Macropsis idae Emelyanov, 1964 Figs. 38–39 Macropsis gracilis Dubovskiy, 1966: 97 (synonymy by Tishechkin, 2002). Description. Head, pro-, and mesonotum pale yellowish, forewings in male brown, in female transparent with brown mesonotal margins (Figs. 38–39). Body length (including tegmina): ♂, 3.7–4.1 mm; ♀, 4.5–4.7 mm. Host. Rosa spp. Distribution. The whole territory of Kazakhstan, mountains of Central Asia; in the extreme northwest of the range reaches Southern Urals and Lower Volga Region, Russia. In Southeastern Kazakhstan was found in low mountains and in river valleys in the plains. Remark. Identification of this species is based on investigation of type specimens from Central Kazakhstan, deposited in ZIN.Published as part of Tishechkin, Dmitri Yu., 2020, Review of the genus Macropsis Lewis, 1836 (Homoptera: Auchenorrhyncha Cicadellidae: Eurymelinae: Macropsini) of Southeastern Kazakhstan with description of new species, pp. 381-405 in Zootaxa 4838 (3) on page 394, DOI: 10.11646/zootaxa.4838.3.4, http://zenodo.org/record/440415
Molecular confirmation of Leucoagaricus idae-fragum (Agaricales, Agaricaceae), and notes on its morphological variability
No full textLeucoagaricus idae-fragum, a nice and very rare pink-lilac lepiotoid species originally described from France, was put into synonymy with the North American taxon Lepiota decorata by Vellinga (2006), only on a morphological basis. In this paper, the independent position of L. idae-fragum from L. decorata is pointed out, based upon the phylogenetic analysis of the nrITS sequences obtained from recently collected specimens of L. idae-fragum from three Italian areas, and from the holotype collection. Morphological investigations of all these collections revealed high variability in shape of the cheilocystidia, spores, inconstant ammonia reaction, characters which have always been considered to be quite stable within a single species and traditionally used for discriminating among species in Leucoagaricus. Full descriptions, with illustrations of fresh basidiomes and of the main macro- and micromorphological features are provided together with a comparison with allied species. </jats:p

Leucocoprinus idae-fragum in a cypress alley nearby Lake Bracciano in Latium
No full textIn the area of the Italian town Trevignano Romano, within the Bracciano-Martignano Regional Natural Park, we have found several rare Leucocoprinus specimens belonging to section Piloselli. In the same cypress alley in precedence, we have reported the presence of the two uncommon species Myriostoma coliforme and a still undefined Battarrea sp. Specifically, in the winter period of recent years, we have found Leucocoprinus pseudopilatianus, Leucocoprinus gaillardii, Leucocoprinus marginatus and particularly, Leucocoprinus idae-fragum. The taxonomic identities of the specimens were confirmed through molecular and phylogenetic analyses. Because information on the extremely rare L. idae-fragum is still limited, a description of these specimens is presented including their peculiar growth environment which seems now under threat of human intervention
Tingkat kematangan gonad dan indeks kematangan gonad udang air tawar macrobrachium idae di Danau Tempe Kabupaten wajo
Get PDFPenelitian ini bertujuan untuk mengetahui tingkat kematangan gonad dan indeks kematangan gonad udang air tawar Macrobrachium idae. Pengambilan sampel udang dilakukan di Danau Tempe Kabupaten Wajo sekali dalam sebulan selama bulan Juni hingga bulan Oktober 2017, sedangkan analisis sampel dilakukan di Laboratorium Biologi Politeknik Pertanian Negeri Pangkep. Sampel udang ditangkap menggunakan alat tangkap serok dengan alat bantu panambe (scoop net with artificial bait) yang dioperasikan oleh nelayan pada malam hari. Sampel udang dimasukkan ke dalam cool box untuk dianalisis di laboratorium. Tingkat kematangan gonad diamati secara morfologi dan dianalisis secara deskriptif. Penentuan indeks kematangan gonad dengan cara membandingkan bobot gonad dengan bobot udang. Hasil penelitian menunjukkan bahwa ovarium udang air tawar M. idae berbentuk oval dengan ukuran dan warna bervariasi sesuai dengan tingkat kematangannya. Berdasarkan karakter morfologi, kematangan gonad udang dapat dibedakan atas empat tingkat, yaitu: TKG I, TKG II, TKG III, dan TKG IV. Indeks kematangan gonad (IKG) udang air tawar M. idae meningkat seiring dengan peningkatan Tingkat Kematangan Gonad (TKG). Nilai IKG udang air tawar M. idae rata-rata berkisar 0,213–7,429 %. Berdasarkan nilai IKG ini, menunjukkan bahwa udang air tawar M. idae dapat memijah lebih dari satu kali dalam setahu
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
An input-output analysis of the "key" sectors in CO2 emissions from a production perspective: an application to the Spanish economy
Get PDFHere we present an approach that allows the identification of the "key" productive sectors responsible for CO2 emission. For this purpose, we develop an input- output methodology from a supply perspective. We focus on the impact of an increase in the value-added of the different productive sectors on total CO2 emissions and we identify the productive sectors responsible for the increase in CO2 emissions when there is an increase in the income of the economy. The approach shows the contribution of the various sectors to CO2 emission from a production perspective and allows us to identify the sectors that deserve more consideration for mitigation policies. This analysis is complementary to the input–output analysis from a demand perspective. TheCO2 emissions,key productive sectors,input-output analysis
