Annonoideae tribe Annoneae) has a narrow taxonomic diversity with only nine extant species, it exhibits a striking diversity in other perspectives: Disepalum s.str. consists of six species with a calyx of two sepals and a fused corolla, and is confined to tropical lowland forests in western Malesia; whereas three species with typical trimerous floral structure have been classified in genus Enicosanthellum, which generally occurs in montane forests in continental Asia. The first species-level molecular phylogeny with extensive sampling of Disepalum species and related taxa was reconstructed in the present study using maximum parsimony (MP), maximum likelihood (ML) and Bayesian inference (BI) methods, based upon cpDNA (matK, trnL-F, ndhF and ycf1) and nDNA (AP3 and PhyA) regions. The resultant phylogeny is well resolved, confirming the monophyletic status of Disepalum s.l. and clarifying the sister relationship between Disepalum s.str. and Enicosanthellum clades. Since the topology is consistent with both taxonomic delimitations (broader delimitation of Disepalum s.l. and narrower circumscription following segregation of Enicosanthellum), morphological character mapping was conducted using parsimony and likelihood approaches to identify synapomorphies and diagnostic characters. Lack of morphological synapomorphies for Enicosanthellum provides a cogent argument against its recognition as a distinct genus, supporting the broader generic delimitation of Disepalum with development of pollen octads and carpophores as synapomorphies. As Enicosanthellum is clearly separated from Disepalum s.str. in several diagnostic characters, the two clades are recognized as distinct subgenera. The functional significance of selected floral, pollen and fruit characters was evaluated. Evolutionary loss of floral chamber in subgen. Disepalum in relation to compression of two petal whorls into one and fusion of contiguous petals was confirmed to be associated with a shift in pollination system. Comparative field studies on pollination ecology revealed a shift from a generalist pollination (including small beetles and fruit flies) in subgen. Enicosanthellum (D. pulchrum) to more specific bee pollination in subgen. Disepalum (D. anomalum), indicating that loss of floral chamber and partial breakdown of protogyny may have promoted the shift. The formation of pollen octads and increased number of carpels in Disepalum may be selectively advantageous when pollinator visits are infrequent, although this would require an extragynoecial compitum for intercarpellary pollen tube growth. Independent evolutionary origins of carpophores in the Annoneae were furthermore inferred, suggesting either carpophores or monocarp stipes have evolved to facilitate exposure of monocarps to frugivores. Molecular dating using an uncorrelated relaxed molecular clock (UCLD) model and two fossil calibrations, ancestral range estimation, and ecological niche modelling across evolutionary time were performed. The results indicate that a vicariance event resulting in a Neotropical-Asian disjunction within the Asimina-Disepalum clade likely coincided with climatic deterioration at the Eocene-Oligocene boundary. The ancestral range of Disepalum was inferred as western Malesia or western Malesia and continental Southeast Asia. Although

It includes c. 130 species of trees, distributed in tropical lowland and submontane forests in tropical Asia, Australia and Melanesia. Previous studies have indicated that Goniothalamus shows a significantly higher diversification rate in comparison to closely related taxa and that its species diversity is the result of a relatively recent radiation. The phylogenetic framework necessary for testing this hypothesis, including the investigation of potential intrinsic and environmental correlates of this putative radiation, and additional biogeographical and evolutionary studies, has not previously been available. Data from nine chloroplast DNA markers (11,214 aligned characters) and 67 ingroup accessions (c. 50% of the species diversity) of Goniothalamus are used for parsimony, maximum likelihood and Bayesian phylogenetic reconstructions. The results confirm the monophyly of Goniothalamus, indicate several strongly supported major subclades, and show that most previously described infrageneric taxa are para- or polyphyletic. Morphological character evolution in Goniothalamus is investigated using ancestral character state reconstructions and phylogenetic analysis of variance. The evolutionary patterns of 19 morphological characters for which a significant phylogenetic signal was identified are discussed in relation to function. Character correlations indicate two main fruit types: small monocarps (average diameter c. 1 cm) with glabrous seeds borne on young growth, which are hypothesized to be predominantly bird-dispersed, and larger (average diameter 1.5 cm) monocarps with hairy seeds borne on older twigs, the trunk or close to the ground, hypothesized to be predominantly mammal dispersed. Synapomorphies of several subclades of the Goniothalamus phylogeny are identified based on the ancestral character reconstructions of 11 categorical characters. Molecular dating is performed using two fossil calibrations, an uncorrelated rates relaxed molecular clock model, and the most comprehensive Annonaceae dataset to date (738 ingroup and 5 outgroup accessions, nine chloroplast markers), with the aim of investigating the historical biogeography of Goniothalamus. Mean divergence time estimates indicate a Goniothalamus crown group age of 23 Ma. Biogeographical analyses infer an ancestral area in western Southeast Asia, two dispersal events from western Southeast Asia to India, and multiple dispersal events from western Southeast Asia eastwards to the Philippines, New Guinea and Australia in the early to late Miocene. Diversification analyses corroborate previous studies which indicated that early Annonaceae diversification was characterized by a low net diversification rate and high relative extinction rate. The results of the present study, however, also indicate that the diversification rate peaked between 9.9 and 0.8 Ma, associated with a low relative extinction rate. Temporally coinciding environmental (tectonic and climatic) factors which may underlie this diversification peak are discussed. In contrast to previous studies, the results do not suggest that the species diversity in Goniothalamus is the result of a rapid, recent radiation. Significant rate shifts are not indicated when using methods that

Available in PDF, EPUB and Kindle. Book excerpt: The Ecology of Papua provides a comprehensive review of current scientific knowledge on all aspects of the natural history of western (Indonesian) New Guinea. Designed for students of conservation, environmental workers, and academic researchers, it is a richly detailed text, dense with biogeographical data, historical reference, and fresh insight on this complicated and marvelous region. We hope it will serve to raise awareness of Papua on a global as well as local scale, and to catalyze effective conservation of its most precious natural assets. New Guinea is the largest and highest tropical island, and one of the last great wilderness areas remaining on Earth. Papua, the western half of New Guinea, is noteworthy for its equatorial glaciers, its vast forested floodplains, its imposing central mountain range, its Raja Ampat Archipelago, and its several hundred traditional forest-dwelling societies. One of the wildest places left in the world, Papua possesses extraordinary biological and cultural diversity. Today, Papua’s environment is under threat from growing outside pressures to exploit its expansive forests and to develop large plantations of oil palm and biofuels. It is important that Papua’s leadership balance economic development with good resource management, to ensure the long-term well-being of its culturally diverse populace.
