Acicularia? weisswasserensis n. sp. and Terquemella? microsphaera n. sp., two new Dasycladales from the Upper Cretaceous (Late Turonian-Santonian) of the Northern Calcareous Alps (Gosau Group, Austria)

Two new dasycladalean algae are described from the Gosau Group of the Northern Calcareous Alps in Austria. The tiny spicules of Acicularia? weisswasserensis n. sp. were found in foraminiferal wacke- to packstones associated with rudist limestones of the Weisswasser locality (Middle Coniacian), Lower Austria. The small globulous Terquemella? microsphaera n. sp. occurs in marls to marly limestones of the Pletzachalm locality (Upper Turonian), Tyrol, and Russbach locality (Upper Santonian), Lower Austria. The Terquemella-Acicularia group requires taxonomic revision; the two forms described herein, however, are clearly distinct from other species, and belong to the smallest representatives of these genera. In addition, Acicularia? aff. magnapora Kuss and morphologically similar forms interpreted as gametophores of unknown larger dasycladales are described.     

Glucosinolate survey of cultivated and feral mashua (Tropaeolum tuberosum Ruíz & PavÓn) in the Cuzco region of Peru

Glucosinolates (GSL) present in cultivated and feral accessions of mashua (Tropaeolum tuberosum í & Pavón) were identified and quantfied by High Performance Liquid Chromatography (HPLC) analysis. The nwin glucosinolates detected were aromatic: 4—Hydroxybenzyl GSL (OHB, Glucosinalbin), Benzyl GSL (B, Glucotropaeolin), and m—Methoxybenzyl GSL (MOB, Glucolimnathin). The total amount of GSL observed ranged from 0.27 to 50.74 micromols per gram (μMol/g) of dried tuber tissue. Most of the low-content GSL accessions are distributed within the cultivated population with a total GSL concentration lower than 5.00 μMol/g of dried tuber tissue. The highest total and specific GSL (OHB, B, and MOB) contents (more than 25.00 μMol/g of dried tuber tissue) were observed in the feral population with few exceptions. in addition, only six different GSL profiles were found: Only MOB; only B; OHB and B; OHB and MOB; B and MOB; and OHB, B and MOB.

A false aciculariacean alga and its origin: an example from the Late Jurassic of the Northern Calcareous Alps,Austria

Slightly curved calcitic plates with marginal pores recalling an aciculariacean alga are common in Late Tithonian reefal platform margin deposits of the Plassen Carbonate Platform of the Northern Calcareous Alps of Austria. Illustrated also from the Western Carpathians, these forms were assigned to the genus Acicularia, e.g., Acicularia elongata Carozzi. It is demonstrated that these algal parts are not reproductive caps of polyphysacean algae (formerly known as acetabulariaceans), but represent sections through scattered articles fragments of the dasycladalean alga Neoteutloporella socialis (Praturlon), more precisely the proximal parts of the laterals. This alga formed reefal bushes at the platform margin near-by to coral-stromatoporoid patches. The characteristic aciculariacean algae recalling fragments occur in bioclastic packstones, a facies adjacent to these dasycladalean algal microreefs.     

Über die Beziehungen zwischen Waldvögeln und Waldameisen

Riassunto Viene riferito su esperimenti condotti in Germania allo scopo di studiare se esiste una eventuale azione competitrice in fatto di nutrimento fra uccelli del bosco e Formiche del gruppoF. rufa e.F. polyctena usate entrambe separatamente come misure di protezione contro gli insetti dannosi alla foresta. Viene documentato che la presenza di colonie delle Formiche determina un aumento degli uccelli del bosco ma sono necessarie ulteriori ricerche per chiarirne le cause.

Nationalization and Globalization Trends in the Wild Mushroom Commerce of Italy with Emphasis on Porcini (<Emphasis Type="Italic">Boletus edulis</Emphasis> and Allied Species)

Nationalization and Globalization Trends in the Wild Mushroom Commerce of Italy with Emphasis on Porcini ( Boletus edulis and Allied Species). This paper presents an historical overview of wild mushroom commerce in Italy, with a focus on recent trends in the production of porcini (Boletus edulis and closely allied species). Over the past century, two major trends—nationalization and globalization—have been apparent in the wild mushroom commerce of Italy. First, a simplified national mushroom menu has emerged through processes of governmental regulation and culinary fashion, but it has come at the expense of differing, localized mushroom traditions which may suffer under the European Union’s free trade principles. Second, Italy has emerged as a focal point of a global market for a small number of mushroom species—particular porcini. While the name porcini has become synonymous with Italian cuisine, and in spite of a vibrant tradition of recreational mushroom collecting in Italy, most of the porcini commercially available in Italy or exported by Italy are no longer of Italian origin. Porcini and other mushrooms now flow into Italy from all over the world—especially from China and eastern Europe—and are then often exported as “Italian porcini.” This globalization of the wild mushroom trade, while offering significant income to rural producers and processors around the globe, has other effects as well, for example, a kind of national branding as “Italian” of globally-produced products, of which porcini is one, that is in direct opposition to some of the European Union’s rules for regional denominations.

Processi di Nazionalizzazione e Globalizzazione nel Commercio Italiano dei Funghi spontanei, con Particolare Riguardo ai Porcini ( Boletus edulis e Specie Affini). Questo articolo presenta una panoramica storica sul commercio dei funghi spontanei in Italia, con particolare riguardo alle recenti tendenze nella produzione dei porcini (Boletus edulis e specie affini). Nello scorso secolo si sono osservate due tendenze principali—di nazionalizzazione e di globalizzazione—nel commercio dei funghi spontanei in Italia. In primo luogo si è affermata nel territorio nazionale una tradizione limitata al consumo di un numero contenuto di specie, sia per effetto di alcune normative che di mode culinarie, ma ciò è avvenuto a discapito di tradizioni locali più ricche, che potrebbero ulteriormente risentire dei principi per il libero scambio all’interno dell’Unione Europea. In secondo luogo, l’Italia si è posta in evidenza come un punto nodale per il mercato globale di alcune specie fungine, in particolare dei porcini. Nonostante quest’ultimo termine sia tradizionalmente associato alla cucina italiana, e nonostante esista in Italia una vivace e radicata tradizione nella raccolta amatoriale dei funghi, la maggior parte dei porcini ivi commercializzati (allo stato fresco, essiccati o variamente conservati) o esportati verso altri paesi non sono più di origine locale. I porcini e altre specie fungine giungono attualmente in Italia da ogni parte del mondo—in modo particolare dalla Cina e dall’Europa orientale—e sono successivamente spesso esportati come “prodotti Italiani.” Questo processo di globalizzazione del mercato dei funghi spontanei, pur offrendo un significativo introito ai raccoglitori e commercianti rurali su tutto il globo, è responsabile di altri effetti, come per l’appunto una sorta di marchio nazionale “Italiano” su alcuni prodotti di provenienza globale, come per l’appunto i porcini, cosa che contrasta con alcune delle regole dell’Unione Europea in materia di denominazioni regionali.

Chemistry and ethnobotany of commercial incense copals copal blanco, copal oro, and copal negro, of North America

The North American commercial incense copals are derived from species of Bursera, Protium (Burseraceae), and Hymenaea (Caesal-piniaceae) but are also distinguished by the technique of harvesting as well as by species. Sixty-eight compounds were identified in three commercial incense copals. The essential oil of copal bianco (probably from B. bipinnata) is dominated by 14.52 ± 1.28% α-copaene and 13.75 ± 1.06% germacrene D. The essential oil of copal oro (probably from H. courbaril) is dominated by 21.35 ± 5.96% α-pinene and 26.51 ± 1.22% limonene. The essential oil of copal negro (probably from P. copal) is dominated by 17.95 ± 1.35% α-pinene, 12.51 ± 0.08% sabinene, and 16.88 ± 2.02% limonene.

Risultati della lotta biologica contro ilDacus oleae Gmel. a mezzo dell'Opius concolor Sz. siculus Mon.

Summary The Author reports on the essays of artificial biological control of the olive fly (Dacus oleae Gmel.) made by himself andGenduso with the specific parasiteOpius c. siculus Mon. found in Sicily. The Authors followingDelanoue's technic have bred theseOpius in laboratory on larvae ofCeratitis capitata Wied; so they were able to release: in 1961 — 1000Opius in a small olive plantation near Palermo; in 1962 — 24000Opius in the island of Pantelleria (Sicily); in 1963 — 40000Opius in the island of Salina (Eolic Islands-Sicily); in 1964 — 180000Opius also in the island of Salina. The releasedOpius are ever reproduced, reducing theDacus pest. From the agricultural standpoint the results have been satisfactory and the Author hope to release a great number ofOpius in the olive plantation of all Eolic islands, in 1965.

Two new species of Aristolochia (Aristolochiaceae) from Brazil and Peru

Aristolochia dalyi, from western Peruvian and Brazilian Amazonia, andA. bahiensis, from Bahia, Brazil, are described and illustrated. The species belong toAristolochia ser.Thyrsicae andA. ser.Hexandrae subser.Anthocaulicae, respectively. A key to the eight western Amazonian species of the seriesThyrsicae is presented.Aristolochia dalyi closely resemblesA. silvatica Barb. Rodr. from the Río Negro basin, andA. bahiensis—the first cauliflorous species ofAristolochia known from the Mata Atlantica—is similar toA. guentheri O. C. Schmidt andA. klugii O. C. Schmidt, from the Western Amazon basin. Characters based primarily on the perianth shape, along with some vegetative features, are used to distinguish the two newly described species from their close relatives.

Neocomian Microfossil Association from the Taft area near Yazd (central Iran)

Summary An assemblage of microfossils, including calcareous green algae (dasycladaleans:Deloffrella quercifoliipora, Bakalovaella elitzae, Salpingoporella cf.muehlbergii, Terquemella sp.,Neomeris sp., andCylindroporella? sp.; Halimedaceans/Gymnocodiaceans:Boueina sp.Permocalculus aff.minutus), red algae (Solenoporaceans?:Marinella lugeoni), cysts of dinoflagellates? (Cadosina fusca fusca, Colomisphaera aff.conferta) and foraminifers (Torinosuella peneropliformis, Charentia cuvillieri, Commaliama sp.) is described from the carbonate beds within the terrigenous-carbonate Sangestan Formation (Upper Jurassic—Neocomian) exposed near the small village of Zereshk, approximately 63 km SW of Yard, central Iran. The micropaleontological assemblage indicates a late Neocomian (Hauterivian) age of the carbonate beds.     

Interaction between the tachinid parasite,Sturmiopsis inferens and granulosis virus in the sugarcane shoot borer,Chilo infuscatellus [Lep.: Crambidae]

Competition between granulosis virus (GV) and the larval parasite,Sturmiopsis inferens Tns. (Tachinidae: Diptera), was studied in 3^rd — and 4^th — instar larvae of the sugarcane shoot borer,Chilo infuscatellus Snellen (Crambidae: Lepidoptera), under laboratory conditions. Mortality due to GV infection and parasitization was 76.8 and 47.6 per cent, respectively, when they were tested separately. But when hosts were infected simultaneously with microfeeding of GV and larval parasite, a significantly low parasitism (5.5%) was obtained compared to 74.8 per cent mortality by GV infection. When the larvae were microfed with the GV 6 days after inoculation with parasitic maggots, mortality due to the virus was reduced significantly to 20.5 per cent, but when the maggot inoculation was preceded by virus microfeeding 6 days before, parasitization was unsuccessful, while 75% of larvae died of virus. Results obtained from field — collected larvae also showed that significantly more parasite puparia were recovered from healthy larvae than from virus — infected larvae. Similar differences in parasitization were not obtained in the case of healthy or virus — infected pupae.      

Post-dispersed pine seed removal and its effect on seedling establishment in a Mexican Temperate Forest

In order to assess the impact of seed removal and seedling establishment for four species of pines, we designed experiments with and without the exclusion of seed removers in three vegetation types (pine forest, oak-alder forest, and subalpine grassland). Seed removal was significantly different between species of pines (P < 0.01), as was the interaction between the vegetation types and category of exclusion (remover) (P < 0.0001). The significant difference in terms of seed removal was between P. patula and P. montezumae (33.0 and 17.9%, respectively). Seed removal was significant between pine forest—without exclusion (20.0%) versus oak-alder forest—without exclusion (7.0%). There was significant interaction between seedling establishment of the pine species and vegetation type (P < 0.0001). Highlighting differences between the pine forest—P. teocote (84.1%) versus oak-alder forest—P. patula (19.0%), oak-alder forest—P. pseudostrobus (45.0%), pine forest—P. patula (20.2%), pine forest—P. pseudostrobus (45.6%), subalpine grassland—P. montezumae (24.3%), subalpine grassland—P. patula (27.9%), and subalpine grassland—P. pseudostrobus (17.5%). The impact of the food preferences of rodents and other granivores for P. patula and P. pseudostrobus seeds, as well as the poor survival of seedlings of these species in the pine and oak-alder forest are both factors which may explain the dominance of P. teocote in the study region.     

Les parasites de la mouche des olives

Zusammenfassung Im vorliegenden Vortrag, der anl?sslich der CILB-Versammlung in Antibes am 21. November 1956 gehalten wurde, erw?hnt der A. die wichtigsten, bis heute in Europa ver?ffentlichten Untersuchungsergebnisse überDacus-Parasiten und gliedert sie in drei zeitliche Hauptperioden. Vor 50 Jahren habenSilvestri und Mitarbeiter die in Italien einheimischen Parasiten der Olivenfliege untersucht und unmittelbar vor dem ersten Weltkrieg hatSilvestri die in Afrika und Australien vorkommendenDacus— oderCeratitis — Parasiten studiert. Von allen, aus den verschiedensten L?ndern importierten Parasitenarten hat sich lediglichOpius concolor in Süditalien akklimatisiert. In den letzten 30 Jahren wurde vorwiegend versucht, die Wirkung der einheimischen Parasiten und R?uber durch Kulturmassnahmen zu erh?hen. Die in Südeuropa vorkommenden Parasiten geh?ren alle zur Superfamilie derChalcidoidea; der einzige bekannte R?uber stellt eine Cecidomyiden-Art dar.

Riassunto Nella presente nota, letta alla riunione della C.I.L.B. a Antibes il 21 novembre 1956, l'Autore elenca i principali studi compiuti in Europa sui parassiti delDacus ole? fino ad oggi, mettendo in evidenza tre periodi fondamentali: il primo periodo concerne le ricerche sui parassiti indigeni (Europa meridionale), intraprese in particolar modo da Silvestri e collaboratori, prima del 1908 circa; il secondo riassume l'intenso lavoro eseguito da Silvestri sui parassiti delDacus ole? eCeratitis capitata in Africa e Australia durante gli anni 1908–1914; l'ultimo periodo, dalla prima guerra mondiale ad oggi, è caratterizzato da sporadici studi sistematici su nuove specie parassite delDacus ole? o d'altri Tripetiti e da un abbandono delle ricerche concernenti parassiti esotici per la lotta biologica contro la mosca delle olive. Sono quindi menzionati i parassiti delDacus attualmente conosciuti nell'Europa meridionale secondo la più recente nomenclatura. L'Aurore conclude con un breve accenno al valore di queste specie a prevede la preparazione di alcuni lavori sulla sistematica dei parassiti finora allevati dalDacus, in e fuori Europa, da parte del Servizio di Identificazione della C.I.L.B.

Die «Neuen Regeln» der Zoologischen Nomenklatur,Ausgearbeitet von der Internationalen Nomenkla-turkommission Anlässlich des XV. Internationalen Kongresses für Zoologie,London 1958

Summary The report gives a preliminary account of the decisions made by the International Commission of Zoological Nomenclature during the XVth International Congress of Zoology held in London in 1958. — The most important of these resolutions deal especially with the newrange of application of the rules of nomenclature (validity from subspecies up to superfamily), thesecondary homonyms (rescission of the permanent invalidity), theprocedure of naming the types (onlyholo-, lecto- andneotypus, as well as thesyntypes are of documentary value for the interpretation of a species; severer regulations were made for the nomination ofneotypes) and finally with theprinciple of priority, which — with certain limitations — found its full confirmation contrary to the principles of continuity and conservation.

Genetic control of several α-amylase isozymes in winter hexaploid wheat

α-Amylase isozymes were detected via electrophoretic separation in a Tris-glycine polyacrylamide gel system (pH 8.4). Three chromosome 6B loci controlling the α-amylase isozyme composition were identified by studying the grain α-amylase patterns in an F_→∞ self-pollinating population of winter common wheat (Donskoi Mayak). The loci were found to take the following order in the long arm of chromosome 6B: cen. cen.—α-Amy-B3—α-Amy-B6—α-Amy-B1     

Faunistic similarity and endemism of earthworms in east mediterranean region

The analysis presents earthworm distribution in eight designated tectonic units (C—Cyprus, EP—East Pondites, ET—East Taurus block, Sc—Sakarya continent, Kb—Kırşehir block, L—the Levant, TM—Taurus–Menderes block, WP—West Pondites) in the East Mediterranean region (EM). It represents a full list of earthworm species (N = 81) of the region and reveals significant faunal similarities between Sc + WP, and between Kb + TM. The new Sc + WP unit is characterized by the presence of archaic (Spermophorodrilus) as well as modern earthworm fauna. In contrast, the second newly established Kb + TM unit is characterized by poorly presented earthworm autochthonous fauna and by a lack of endemic species. The analysis done on the species list (N = 73) representing the autochthonous family Lumbricidae showed statistically supported separation of L and EP between themselves and from other designated units. The Levant, part of the Arabian tectonic plate, is characterized by a high level of endemism in ancient (Healyella) and modern (Dendrobaena, Perelia) genera, and by the lack of archaic genera. The EP harbors unique species representing archaic (Eophila), ancient (Healyella), and modern (Allolobophora, Aporrectodea, Dendrobaena and Eisenia) earthworm genera in the EM. The analysis also indicates origin of earthworm fauna in TM and faunistic relationships among the designated units. Clearly, the present-day division of the EM earthworm fauna shows recognizable influences of tectonic history.
