Received: 25 March 2016 Returned for revision: 1 August 2016 Editorial decision: 3 November 2016 Published electronically: 10 January 2017 Background and Aims The breadfruit genus (Artocarpus, Moraceae) includes valuable underutilized fruit tree crops with a centre of diversity in Southeast Asia. It belongs to the monophyletic tribe Artocarpeae, whose only other members include two small neotropical genera. This study aimed to reconstruct the phylogeny, estimate diver- gence dates and infer ancestral ranges of Artocarpeae, especially Artocarpus, to better understand spatial and tem- poral evolutionary relationships and dispersal patterns in a geologically complex region. Methods To investigate the phylogeny and biogeography of Artocarpeae, this study used Bayesian and maximum likelihood approaches to analyze DNA sequences from six plastid and two nuclear regions from 75% of Artocarpus species, both neotropical Artocarpeae genera, and members of all other Moraceae tribes.

I Is the Sunda-Sahul Floristic Exchange Ongoing?
Is the Sunda-Sahul floristic exchange ongoing? A study of distributions, functional traits, climate and landscape genomics to investigate the invasion in Australian rainforests By Jia-Yee Samantha Yap Bachelor of Biotechnology Hons. A thesis submitted for the degree of Doctor of Philosophy at The University of Queensland in 2018 Queensland Alliance for Agriculture and Food Innovation i Abstract Australian rainforests are of mixed biogeographical histories, resulting from the collision between Sahul (Australia) and Sunda shelves that led to extensive immigration of rainforest lineages with Sunda ancestry to Australia. Although comprehensive fossil records and molecular phylogenies distinguish between the Sunda and Sahul floristic elements, species distributions, functional traits or landscape dynamics have not been used to distinguish between the two elements in the Australian rainforest flora. The overall aim of this study was to investigate both Sunda and Sahul components in the Australian rainforest flora by (1) exploring their continental-wide distributional patterns and observing how functional characteristics and environmental preferences determine these patterns, (2) investigating continental-wide genomic diversities and distances of multiple species and measuring local species accumulation rates across multiple sites to observe whether past biotic exchange left detectable and consistent patterns in the rainforest flora, (3) coupling genomic data and species distribution models of lineages of known Sunda and Sahul ancestry to examine landscape-level dynamics and habitat preferences to relate to the impact of historical processes. First, the continental distributions of rainforest woody representatives that could be ascribed to Sahul (795 species) and Sunda origins (604 species) and their dispersal and persistence characteristics and key functional characteristics (leaf size, fruit size, wood density and maximum height at maturity) of were compared.

Moraceae of Papua George D. Weiblen
Moraceae of Papua george d. weiblen Number of Genera and Species The 37 genera of Moraceae have a broad range of inflorescence forms, pollina- tion syndromes, and breeding systems (Datwyler and Weiblen 2004). Most of the 1,100 species are figs (Ficus) known for a unique inflorescence and obligate polli- nation mutualism with fig wasps. In Papua, there are ten genera and 173 described species, dominated by Ficus, with 151 species, and followed by Artocarpus, with seven. Distribution and Habitat Moraceae are distributed from tropical to temperate forests throughout the world but the great majority of species are restricted to tropical rainforest. In New Guinea, the family occurs from the lowlands to cloud forest up to 2,400 m above sea level. Ficus is a prominent member of forest communities throughout the island in terms of local species richness and abundance (Weiblen 1998). About 70% of these species are endemic to the island and alpha diversity is extreme. In a lowland rainforest, for example, it is not uncommon to encounter up to 50 Ficus species within a few hundred hectares. Species turnover at a regional scale, on the other hand, appears to be quite low. In a comparison of four lowland rainforests across the Ramu and Sepik river basins, for instance, at least half of the Ficus species are shared between any two sites, even those separated by 500 km (G.D. Weiblen, unpublished data). The uneven density of collections across the island make it difficult to discern patterns of local endemism but most species appear to be widespread, perhaps related to dispersal by vertebrate frugivores (Dumont et al.

Taxonomy and Conservation Status of Pteridophyte Flora of Sri Lanka R.H.G
Taxonomy and Conservation Status of Pteridophyte Flora of Sri Lanka R.H.G. Ranil and D.K.N.G. Pushpakumara University of Peradeniya Introduction The recorded history of exploration of pteridophytes in Sri Lanka dates back to 1672-1675 when Poul Hermann had collected a few fern specimens which were first described by Linneus (1747) in Flora Zeylanica. The majority of Sri Lankan pteridophytes have been collected in the 19th century during the British period and some of them have been published as catalogues and checklists. However, only Beddome (1863-1883) and Sledge (1950-1954) had conducted systematic studies and contributed significantly to today’s knowledge on taxonomy and diversity of Sri Lankan pteridophytes (Beddome, 1883; Sledge, 1982). Thereafter, Manton (1953) and Manton and Sledge (1954) reported chromosome numbers and some taxonomic issues of selected Sri Lankan Pteridophytes. Recently, Shaffer-Fehre (2006) has edited the volume 15 of the revised handbook to the flora of Ceylon on pteridophyta (Fern and FernAllies). The local involvement of pteridological studies began with Abeywickrama (1956; 1964; 1978), Abeywickrama and Dassanayake (1956); and Abeywickrama and De Fonseka, (1975) with the preparations of checklists of pteridophytes and description of some fern families. Dassanayake (1964), Jayasekara (1996), Jayasekara et al., (1996), Dhanasekera (undated), Fenando (2002), Herat and Rathnayake (2004) and Ranil et al., (2004; 2005; 2006) have also contributed to the present knowledge on Pteridophytes in Sri Lanka. However, only recently, Ranil and co workers initiated a detailed study on biology, ecology and variation of tree ferns (Cyatheaceae) in Kanneliya and Sinharaja MAB reserves combining field and laboratory studies and also taxonomic studies on island-wide Sri Lankan fern flora.

MORACEAE Genera Other Than FICUS (C.C
Flora Malesiana, Series I, Volume 17 / Part 1 (2006) 1–152 MORACEAE GENera OTHer THAN FICUS (C.C. Berg, E.J.H. Corner† & F.M. Jarrett)1 FOREWORD The following treatments of Artocarpus, Hullettia, Parartocarpus, and Prainea are based on the monograph by Jarrett (1959–1960) and on the treatments she made for this Flora in cooperation with Dr. M. Jacobs in the 1970s. These included some new Artocarpus species described in 1975 and the re-instatement of A. peltata. Artocarpus lanceifolius subsp. clementis was reduced to the species, in A. nitidus the subspe- cies borneensis and griffithii were reduced to varieties and the subspecies humilis and lingnanensis included in var. nitidus. The varieties of A. vrieseanus were no longer recognised. More new Malesian species of Parartocarpus were described by Corner (1976), Go (1998), and in Artocarpus by Kochummen (1998). A manuscript with the treatment of the other genera was submitted by Corner in 1972. Numerous changes to the taxonomy, descriptions, and keys have been made to the original manuscripts, for which the present ﬁrst author is fully responsible.
