Author abbrev. (botany) Entwisle

Timothy (Tim) John Entwisle (born 1960), is an Australian botanist, [2] much of whose research work is in phycology (algae). See for example the articles. [3] [4] [5] [6] He was awarded a Ph.D. from La Trobe University in 1986 for work on the taxonomy of Vaucheria . [7]

Contents

He was New South Wales’ Government Botanist in 2007 and 2008, [8] [9] and for eight years was the executive director of the Royal Botanic Gardens Sydney (2003–2011). [10] [11] Subsequently, he was director of Conservation, Living Collections and Estates, Kew, London from 2011, [12] [13] and from 2013 to 2023 he was director and chief executive of the Royal Botanic Gardens Victoria. [10] He is an honorary professorial fellow at the University of Melbourne and is currently (2020) president of the International Association of Botanic Gardens. [14]

As director of the Royal Botanic Gardens Sydney, Entwisle managed Sydney's Royal Botanic Gardens, the Mount Tomah Botanic Garden, in the Blue Mountains and the Mount Annan Botanic Garden, near Camden, [13] and at Kew, he was responsible for Kew Gardens, Wakehurst Place, and the Millennium Seed Bank. [13] A major project on taking up the Victorian appointment has been succession planning for the gardens under climate change. [15]

He values communicating with the general public as well as the scientific community. He is interviewed on radio frequently [16] [17] [18] [19] [20] [21] and had a program, Talking Plants, on ABC radio,, [22] which ran from December 2014 [23] to January 2016. [24] He is a regular contributor to the ABC radio program, Blueprint for living. [25] He also writes blogs on plants, [26] [27] and articles for Gardening Australia. [28]

In 2022, Tim was on the panel of expert judges for ABC's ‘Australia's Favourite Tree’ competition, where he appeared on episodes of ABC TV's show Catalyst. [29] He also helped select the short-listed trees for a public poll which drew 265,000 responses over three weeks and contributed to ABC's live blog [30] and various ABC radio conversations about the poll.

In the same year, Thames &Hudson published his memoir called ‘Evergreen: The Botanic Life of a Plant Punk’ [31] about his experiences as director of Royal Botanic Gardens in Sydney, Kew and Melbourne, as well as his life influences and perspectives, particularly about the role of public gardens. His love of garage music and algae feature in the early years, and there is a chapter on the very public removal of ten fig trees in Sydney during his time as director there.

He continues to publish in phycology. [32] [33] [34]

Honours

The algal genus, Entwisleia F.J.Scott, G.W.Saunders & Kraft, 2013, was named for him. [36] [37]

<span class="mw-page-title-main">Florideophyceae</span> Class of algae

Florideophyceae is a class of exclusively multicellular red algae. They were once thought to be the only algae to bear pit connections, but these have since been found in the filamentous stage of the Bangiaceae. They were also thought only to exhibit apical growth, but there are genera known to grow by intercalary growth. Most, but not all, genera have three phases to the life cycle.

Thorea is a genus of freshwater algae in the Phylum Rhodophyta. Thorea is a small alga with filaments up to 200 cm long, dark green in colour and not red as are marine Rhodophyta. The filaments have only as few secondary branches.

<span class="mw-page-title-main">Conceptacle</span> Specialized cavities in algae

Conceptacles are specialized cavities of marine and freshwater algae that contain the reproductive organs. They are situated in the receptacle and open by a small ostiole. Conceptacles are present in Corallinaceae, and Hildenbrandiales, as well as the brown Fucales. In the Fucales there is no haploid phase in the reproductive cycle and therefore no alternation of generations. The thallus is a sporophyte. The diploid plants produce male (antheridia) and female (oogonia) gametangia by meiosis. The gametes are released into the surrounding water; after fusion, the zygote settles and begins growth.

<span class="mw-page-title-main">Red algae</span> Division of plant life

Red algae, or Rhodophyta, are one of the oldest groups of eukaryotic algae. The Rhodophyta comprises one of the largest phyla of algae, containing over 7,000 currently recognized species with taxonomic revisions ongoing. The majority of species (6,793) are found in the Florideophyceae (class), and mostly consist of multicellular, marine algae, including many notable seaweeds. Red algae are abundant in marine habitats but relatively rare in freshwaters. Approximately 5% of red algae species occur in freshwater environments, with greater concentrations found in warmer areas. Except for two coastal cave dwelling species in the asexual class Cyanidiophyceae, there are no terrestrial species, which may be due to an evolutionary bottleneck in which the last common ancestor lost about 25% of its core genes and much of its evolutionary plasticity.

<i>Hildenbrandia</i> Genus of algae

Hildenbrandia is a genus of thalloid red alga comprising about 26 species. The slow-growing, non-mineralized thalli take a crustose form. Hildenbrandia reproduces by means of conceptacles and produces tetraspores.

<span class="mw-page-title-main">Batrachospermaceae</span> Family of algae

Batrachospermaceae is a family of fresh water red algae (Rhodophyta). Genera within the Batrachospermaceae generally have a "Lemanea-type" life history with carpospores germinating to produce chantransia. Sporophyte phase with meiosis occurs in an apical cell to produce the gametophyte stage. Pit connections have two pit plug cap layers with the other layer enlarged. This family of freshwater red algae is uniaxial, meaning each filament with a single apical cell. The genera included within Batrachospermaceae are listed in the table below.
