“…Many Marcgraviastrum and Marcgravia species are reported to be bat pollinated (Vogel, ; Sazima & Sazima, ; Tschapka & von Helversen, ; Sazima, Buzato & Sazima, ; Zusi & Hamas, ; Dressler & Tschapka, ; Muchhala & Jarrín Valladares, ; Tirado Herrera et al ., ; Dressler, 2004a, b; Tschapka et al ., ; Simon et al ., ), whereas M. nepenthoides is most probably pollinated by larger arboreal mammals, such as opossums (Tschapka & von Helversen, ). Only little is known about the interaction of pollinators with Norantea flowers and nothing about the genus Pseudosarcopera .…”

Based on molecular phylogenetic studies, Balsaminaceae, Tetrameristaceae (including Pellicieraceae) and Marcgraviaceae form the strongly supported first branching clade in the asterid order Ericales. Marcgraviaceae and Tetrameristaceae were proposed to be closely related in pre‐molecular studies, but the systematic position of Balsaminaceae has been controversial for some time and a relationship with the other two families was never suggested in pre‐molecular/pre‐cladistic times. However, interfamilial relationships in the clade are still unclear because of conflicting phylogenetic hypotheses from molecular analyses. In order to assess the validity of these molecular hypotheses from a morphological point of view, the floral morphology, anatomy and histology of Balsaminaceae, Tetrameristaceae and Marcgraviaceae are comparatively studied in detail. In addition, earlier literature is reviewed. The monophyly of the balsaminoid clade is strongly supported by floral structure, and a series of potential floral synapomorphies is identified for the clade. Prominent features shared by the three families include broad and dorsiventrally flattened filaments, thread‐like structures lining the stomia of dehisced anthers, secretory inner morphological surfaces of the gynoecium, ovules intermediate between uni‐ and bitegmic, incompletely tenuinucellar ovules, fruits with persistent style and stigma, seeds lacking endosperm and several anatomical/histological traits. The families are also distinctive because the bracts and/or sepals are petaloid and nectariferous. Further, the floral structure supports a sister group relationship between Balsaminaceae and Tetrameristaceae rather than any of the other possible interfamilial relationships. These two families share a caducous calyx, post‐genital fusion/coherence of filaments and ovary surface, latrorse anther dehiscence, commissural carpel lobes and ovules with a thickened funiculus and a constricted chalazal region. The occurrence of these features in Ericales is discussed. Future structural studies in other ericalean lineages and additional molecular studies are needed to further test these features with respect to their systematic value for the balsaminoid clade. Some may turn out to be true synapomorphies, whereas others may be recognized as plesiomorphies, as they may be more widely spread in Ericales than currently thought. © 2013 The Linnean Society of London, Botanical Journal of the Linnean Society, 2013, 173, 325–386.

“…However, we found two more species of the genus Marcgravia at Rara Avis, M. caudata and M. brownei, where so far no data on visitors are available. While chiropterophily appears unlikely in the exceptionally small M. caudate, the inflorescences of M. brownei are larger than most Marcgravia with confirmed bat visits (Sazima and Sazima, 1980;Tirado Herrera et al, 2003;Tschapka and Helversen, 1999;Zusi and Hamas, 2001). Solely, M. polyantha Delpino (Sazima et al, 1999) may reach similar dimensions.…”

“…In a lowland Atlantic rainforest of Costa Rica four species of Marcgravia were found to coexist, all of which were visited by bats; however, one species (M. nepenthoides) showed distinct adaptations to the pollination by larger, arboreal mammals like opossums (Tschapka and Helversen, 1999). Meanwhile, several other authors Muchhala and Jarrı´n Valladares, 2002;Sazima et al, 1999;Tirado Herrera et al, 2003;Zusi and Hamas, 2001) have added reports of bat visits to various species belonging to the genus.…”

“…Dysoxylum maoto and Dysoxylum samoensis, both indigenous to Samoa (Whistler 1994), are in peak fruit from January through September (Webb et al 1999). We recorded visitation and feeding based on scan sampling (Altmann 1974), a method used commonly to assess behaviour of both birds and fruit bats (Pitter and Christiansen 1997;Sun and Moermond 1997; Ochoa-Acuna and Kunz 1999;Munoz-Romo 2006), as well as to investigate visitation and feeding at focal trees (Boinski and Scott 1988;Tirado Herrera et al 2003;Kirika et al 2008). Observations at Erythrina focal trees were made between 05:00 and 09:00 to capture peak feeding times for most avian and fruit-bat species.…”

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.
