As the Director, Dr. Horvitz spearheaded many activities that enabled the Gifford Arboretum to play all of these roles suc- cessfully. She improved the interpretive signage in the Arboretum, and increased the value of the collection by planting trees that represent a wide variety of fami- lies.

    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.

At least one complete plastid genome sequence has been reported for all of the 10 genera except Microcycas, making it an ideal plant group to conduct comprehensive plastome comparisons at the genus level. This article reports for the first time the plastid genome of Microcycas calocoma. The plastid genome has a length of 165,688 bp with 134 annotated genes including 86 protein-coding genes, 47 non-coding RNA genes (39 tRNA and eight rRNA) and one pseudogene. Using global sequence variation analysis, the results showed that all cycad genomes share highly similar genomic profiles indicating significant slow evolution and little variation. However, identity matrices coinciding with the inverted repeat regions showed fewer similarities indicating that higher polymorphic events occur at those sites. Conserved non-coding regions also appear to be more divergent whereas variations in the exons were less discernible indicating that the latter comprises more conserved sequences.

    In the Company One Botanist’s Humbling Encounters with Ancient Dioons ofof GiantsGiants Article and photos (unless otherwise indicated) by Jody Haynes 1,400 years prior! This population occurs in tropical oak forest alongside a small stream; such a setting is quite common for many of the 30+ populations of this species in Honduras. There were no cones evident, but seedlings were present. Due to its remoteness and relative inaccessibility, this population—and the giants therein— is almost certainly not threatened. During the HN03 expedition, Mark and I visited more than 20 populations of Dioon mejiae, documented at least ten more, and elevated the conservation status of this species to Not Threatened from previous assessments suggesting that it was Rare (Lucas & Synge, 1978) or Vulnerable (Mace et al., 1992; Walter & Gillett, 1998). We also revised the estimate of the total number of wild plants, increasing it 120-fold from the previous estimate of 5,000 (Osborne, 1995) to no less than 600,000 mature plants spread across 10,000 ha in northern Olancho and eastern Yoro (Haynes & Bonta, 2003; Haynes & Bonta, In press). Dioon spinulosum—The popula- tion of this species that we visited in northern Oaxaca is approximately 120 km from the type locality. The plants were growing on a karst (limestone) mogote rising up out of the surrounding farm fields (Fig. 2). Many large and hundreds of medium-sized and juvenile plants were growing on this mogote. In one area, female cones and seedlings were abundant, where- as cones and seedlings were Fig. 1. The author is dwarfed by a giant Dioon mejiae in Olancho, Honduras essentially absent in another (photo by Mark Bonta).

    Rainforest Trees Suitable for Birds

    1 RAINFOREST TREES SUITABLE FOR BIRDS When planting out your garden or plots of native rainforest, it is important to have a range of suitable species, which produce flowers and/or fruit over the whole year. This is to provide birds, with a reasonably reliable food supply. Most plant species listed are native to the Northern Rivers and south-east Queensland. Those species native to north east Queensland are denoted by NEQ. The species covered include those with nectar rich flowers and those with fruit/seeds.
