A total of 61 dried bee pollen samples collected in four Brazilian macro-regions within 19 municipalities were analyzed to identify the sources used by Apis mellifera (L.) for pollen production and to enable a more accurate product certification. Sample preparation followed the standard methodology, including washing the pollen grains with ethanol and then with water and homogenising the sediment in a water/glycerine solution for microscopic observation. Pollen counts included at least 500 pollen grains per sample. Only six samples, presenting a unique species or pollen type comprising more than 90% of the pollen sum, were considered monofloral, including Ambrosia sp., Cecropia sp.,Eucalyptus sp., Fabaceae, Mimosa scabrella (Benth.) spp. and Schinus sp. pollen types. The most frequent pollen types of the heterofloral pollen batches, based on a counting limit of 45%, included Anadenanthera sp., Asteraceae,Brassica sp., Caesalpiniaceae, Cocos nucifera (L.) sp., Mimosa caesalpiniaefolia (Benth.) sp., Mimosa verrucosa(Benth.) sp., and Myrcia sp. pollen types. This result may be related to the great diversity of the Brazilian flora contributing to heterofloral pollen loads and honeys.

“…A exposição do pólen ocorre cerca de 30 minutos após a antese. O pólen é relativamente pequeno, se comparado ao de outras mirtáceas (Barth & Barbosa 1972), com superfície granulosa e seca, o que o torna facilmente transportável pelo vento.…”

-(Floral biology and reproductive phenology of the camu-camu (Myrciaria dubia (H.B.K.) McVaugh, Myrtaceae) in the State of Pará, Brazil). The camu-camu (Myrciaria dubia (H. B.K.) McVaugh, Myrtaceae) is a native fruit tree found on seasonaly flooded banks of Amazonian rivers and lakes, which is being domesticated for cultivation on non-flooded areas. Its high ascorbic acid content, approximately 2,800 mg.100g -1 of pulp has increased the demand for local market and exportation. The floral biology and reproductive phenology of camu-camu were investigated in 1997 and 1998. The studies were carried out in orchards at Embrapa Amazônia Oriental, located in Belém and in areas of natural occurrence in Santarém and Oriximiná, Pará State, northern Brazil. Direct observations on the visitors behavior were done, as well as capturing of specimens for identification. M. dubia showed inflorescences with white, polyandrous, hermaphroditic flowers. Anthesis occurred between 5:00 to 7:00 a.m. The pollen grains are dry, easily carried by wind or gravity, being the main flower resource. The osmophores are located at the calyx, corolla, anthers and stigma. The flowering phenology was "steady-state" type, and showed a peak in March. Fruitification was higher in July. Partial leaf fall was observed in all the studied plants, mainly in November. The main flower visitors were Nannotrigona punctata and Trigona pallens (Meliponinae), as well as small beetles (Chrysomelidae). The stingless bees were considered the legitimate pollinators. RESUMO -(Biologia floral e fenologia reprodutiva do camu-camu (Myrciaria dubia (H.B.K.) McVaugh, Myrtaceae) no Estado do Pará, Brasil). O camu-camu (Myrciaria dubia (H.B.K.)McVaugh, Myrtaceae) é uma fruteira nativa que ocorre nas margens de rios e lagos inundáveis da Amazônia, e está sendo domesticada visando o cultivo em terra firme. O alto teor de ácido ascórbico nos frutos, cerca de 2.800 mg.100g -1 de polpa, fortalece a demanda para consumo no país e exportação. No período de 1997 a 1998, investigou-se a biologia floral e fenologia reprodutiva do camu-camu, em plantios da Embrapa Amazônia Oriental, em Belém, e em áreas de ocorrência natural, em Santarém e Oriximiná, no Estado do Pará, norte do Brasil. Observações diretas sobre o comportamento dos visitantes foram acompanhadas da coleta de espécimens para identificação e registro fotográfico. M. dubia apresenta inflorescências com flores brancas, hermafroditas e poliândricas. A antese ocorre entre as 5:00 e 7:00 h. O pólen é seco e facilmente transportado pelo vento ou gravidade, sendo o principal recurso e atrativo floral. Os osmóforos estão localizados no cálice, corola, anteras e estigma. Constatou-se que a fenofase de floração foi do tipo "steady-state", sendo mais expressiva em março e a frutificação teve um pico no mês de julho. Observou-se desfolha parcial em todas as plantas estudadas, principalmente em novembro. Os principais visitantes foram Nannotrigona punctata e Trigona pallens (Meliponinae) e pequenos besouros (Chrysomelidae). A...

“…The present study examined extant Myrtaceae taxa from the Bega Swamp area with light microscopy and compared images of Myrtaceae pollen grains from various sections of Singh's 1980 core using visual character comparison and a Lucid key of extant Myrtaceae pollen morphology (Thornhill unpublished) with the aim of correlating extant and fossil pollen. Pollen of the plant family Myrtaceae is characterised by a syncolpate or parasyncolpate appearance, although some Myrtaceae tribes are brevicolpate and asyncolpate (Thornhill unpublished data), with many studies conducted on the pollen of the family or specific groups within (Pike 1956;McIntyre 1963;Churchill 1968;Barth and Barbosa 1973;Graham 1980;Gadek and Martin 1981;Gadek and Martin 1982;Patel et al 1984;Van Wyk and Dedekind 1985;Martin and Gadek 1988;Chalson and Martin 1995;Pickett and Newsome 1997;Parnell 2003;Eliseu and Dinis 2008). It has been said that at the generic and species levels, separation of taxa can be difficult or impossible (Pickett and Newsome 1997), but a number of useful and distinctive characters have been created to tackle the task (Dodson 1974;Chalson and Martin 1995).…”

terra australis 32Terra Australis reports the results of archaeological and related research within the south and east of Asia, though mainly Australia, New Guinea and island Melanesia -lands that remained terra australis incognita to generations of prehistorians. Its subject is the settlement of the diverse environments in this isolated quarter of the globe by peoples who have maintained their discrete and traditional ways of life into the recent recorded or remembered past and at times into the observable present.Since the beginning of the series, the basic colour on the spine and cover has distinguished the regional distribution of topics as follows: ochre for Australia, green for New Guinea, red for South-East Asia and blue for the Pacific Islands. From 2001, issues with a gold spine will include conference proceedings, edited papers and monographs which in topic or desired format do not fit easily within the original arrangements. All volumes are numbered within the same series. Copyright of the text remains with the contributors/authors, 2009. This book is copyright in all countries subscribing to the Berne convention.

List of volumes in Terra AustralisRabbit dung dots a lake bottom dry since their coming -only once, last century, after seven inches of rain a farmer had to rescue his sheep by boat.The roo bounces down-slope, a brown branch crackling.The professor's eye, noting the local runoff and what the westerlies do, observes seas that rush in and out of a continent's middle, salt lakes spreading and emptying, hills pimpling up and down with cartoon-like speed, or gullying themselves into extinction, rainforests and deserts zipping back and forth like Tom and Jerry. A human mouse plague swiftly swarms, perhaps soon gone.Impermanent planet. Impermanent surface. All under air and water. The lunette is a wave, a dumper of sand, a collapsing tower in the mad rabbit years when its top blew off and old bones winked through, with a vault's worth of fine stone cores.Once so simply mislaid in sand, now so obligingly sluiced out to the un-subincised world that smiles at stone knives. terra australis 32Altered Ecologies: Fire, climate and human influence on terrestrial landscapes v You might as well offer your table knife to a carpenter.Cane grass and the Dreamtime's stone fight the eroding rivulets together.
