    Description: The Holocene, Ahead of Print. 〈br/〉In this paper, we provide a comprehensive overview of the state-of-knowledge of dust flux and variability in time and space in different sectors of East Antarctica during the Holocene. By integrating the literature data with new evidences, we discuss the dust flux and grain-size variability during the current interglacial and its provenance in the innermost part of the East Antarctic plateau as well as in peripheral regions located close to the Transantarctic Mountains. The local importance of aeolian mineral dust aerosol deflated from low-elevation areas of peripheral East Antarctica is also discussed in the light of new data from several coastal, low-elevation sites.

    Description / Table of Contents: Résumé L'auteur a observé en laboratoire l'activité de récolte des ouvrières deCamponotus nylanderi Em. Au moyen d'observations régulières sur de petites colonies provenant de la Sicile, on prouve que l'activité en question est exclusivement nocturne au moins pendant l'été. Ce rythme d'activité persiste pendant quelques jours en conditions d'éclairage continu et de température irrégulièrement variable.C. nylanderi, est la seule espèce de la myrmecofaune italienne ayant une activité de récolte exclusivement nocturne: c'est un trait de comportement qu'on trouve seulement chez les espèces deCamponotus des déserts chauds, systématiquement voisines deC. nylanderi.
    Abstract: Zusammenfassung Der Verfasser studiert die Sammeltätigkeit der Arbeiterinnen desCamponotus nylanderi Em. Nach systematischer Beobachtung einiger Kolonien, die aus Sizilien stammen, beweist der Verf. dass die sommerliche Sammeltätigkeit ausschliesslich in der Nacht vorsichgeht. Im Herbst kann man auch während des Tages eine geringe Tätigkeit beobachten. Im Dauerlicht (unter uregelmässig wechselnder Temperatur) ist es möglich den Tätigkeitsrhytmus noch für einige Tage zu verfolgen.C. nylanderi ist die einzige Art des italienischen Ameisenfauna, bei der man eine solche nächtliche Aktivität vorfindet. Ein solches Verhalten kommt nur bei verwandtenCamponotus-arten vor, die die warmen Wüsten bewohnen.
    Notes: Riassunto L'Autore, dopo una rivista delle attuali conoscenze sui ritmi di attività delle formiche, studia l'attività di foraggiamento delCamponotus nylanderi Em. e segnala come, almeno nel periodo estivo, essa sia esclusivamente notturna con due massimi di attività (attorno alle ore 21 ed alle ore 2) nella prima e nella seconda metà della notte. In autunno, seppure molto ridotta, l'attività persiste anche nelle ore diurne. In luce costante (e temperatura irregolarmente variabile), l'attività periodica perdura ancora quattro o cinque giorni per poi divenire completamente aritmica. Un'attività notturna quale quella qui illustrata riveste un particolare interesse per la sua unicità in tutta la fauna mirmecologica italiana e per l'analogia che presenta con quella di alcuni affiniCamponotus tropicali.

    Notes: Summary: The traditional hypothesis that ant soldiers originate from large size workers is rejected in favour of their direct origin from gynes. This conclusion is supported by the first report of soldiers smaller than workers, by an intercaste morphometric comparative analysis by means of D'Arcy Thompson's transformation grids and by phylogenetic studies on Cephalotes showing that the cephalic shield appeared ancestrally among soldiers and only later among gynes. The same conclusion flows from facts already known but hitherto misunderstood and stressed in this paper such as: 1) there are species of Cephalotes with soldiers with incomplete cephalic shield and no gyne shield and other species with complete soldier shield but only incomplete gyne shield; 2) the phragmotic behaviour is exercised by workers and soldiers and not by gynes but its morphological correlate, i.e., the shield-shaped head, occurs among soldiers and gynes and not in workers. These observations prove that the selection pressure for the shield morphology acts on workers and soldiers and not on gynes but its morphological correlate actually appears first in soldiers, later in gynes and never in workers. These data sharply contrast with a worker origin of soldiers and are perfectly consistent with the hypothesis of a separate origin of soldiers directly from gynes.

    Description / Table of Contents: Zusammenfassung Obwohl eine funktionelle Monogynie bei Ameisen, der grossen ethologischen Plastizität dieser Tiere wegen, nur sehr schwer nachweisbar ist, enthalten die Beobachtungen vonBaroni-Urbani (1968) anMyrmecina graminicola bemerkenswerte Hinweise auf 3 der fünf vonPardi bei Wespen festgestellten klassischen Merkmale dieses Verhaltens. Trotz zahlreichen Literaturangaben bleibt das Problem der funktionellen Monogynie bei Ameisen immer noch recht unabgeklärt. In einer Arbeit vonBuschinger (1967), worin der Verfasser über ein weiteres Merkmal funktioneller Monogynie beiLeptothotax gredleri berichtet, findet es eine zusätzliche Bestätigung.
    Notes: Summary Functional monogyny is very difficult to demonstrate in ants because of the great behavioural plasticity of these animals.Baroni-Urbani (1968) observed inMyrmecina graminicola 3 of the five features which are characteristic of this behaviour according to the Pardi's classical works on wasps. In spite of the abundant literature data, these represent the most complete documentation in ants. However, they are supported also by a work ofBuschiner (1967) who found another character of functional monogyny inLeptothorax gredleri.
