Highlights of the Museum of Zoology Highlights on the Blue Route
Highlights of the Museum of Zoology Highlights on the Blue Route Ray-finned Fishes 1 The ray-finned fishes are the most diverse group of backboned animals alive today. From the air-breathing Polypterus with its bony scales to the inflated porcupine fish covered in spines; fish that hear by picking up sounds with the swim bladder and transferring them to the ear along a series of bones to the electrosense of mormyrids; the long fins of flying fish helping them to glide above the ocean surface to the amazing camouflage of the leafy seadragon… the range of adaptations seen in these animals is extraordinary. The origin of limbs 2 The work of Prof Jenny Clack (1947-2020) and her team here at the Museum has revolutionised our understanding of the origin of limbs in vertebrates. Her work on the Devonian tetrapods Acanthostega and Ichthyostega showed that they had eight fingers and seven toes respectively on their paddle-like limbs. These animals also had functional gills and other features that suggest that they were aquatic. More recent work on early Carboniferous sites is shedding light on early vertebrate life on land. LeatherbackTurtle, Dermochelys coriacea 3 Leatherbacks are the largest living turtles. They have a wide geographical range, but their numbers are falling. Eggs are laid on tropical beaches, and hatchlings must fend for themselves against many perils. Only around one in a thousand leatherback hatchlings reach adulthood. With such a low survival rate, the harvesting of turtle eggs has had a devastating impact on leatherback populations. Nile Crocodile, Crocodylus niloticus 4 This skeleton was collected by Dr Hugh Cott (1900- 1987). -
A Synopsis of the Pre-Human Avifauna of the Mascarene Islands
– 195 – Paleornithological Research 2013 Proceed. 8th Inter nat. Meeting Society of Avian Paleontology and Evolution Ursula B. Göhlich & Andreas Kroh (Eds) A synopsis of the pre-human avifauna of the Mascarene Islands JULIAN P. HUME Bird Group, Department of Life Sciences, The Natural History Museum, Tring, UK Abstract — The isolated Mascarene Islands of Mauritius, Réunion and Rodrigues are situated in the south- western Indian Ocean. All are volcanic in origin and have never been connected to each other or any other land mass. Despite their comparatively close proximity to each other, each island differs topographically and the islands have generally distinct avifaunas. The Mascarenes remained pristine until recently, resulting in some documentation of their ecology being made before they rapidly suffered severe degradation by humans. The first major fossil discoveries were made in 1865 on Mauritius and on Rodrigues and in the late 20th century on Réunion. However, for both Mauritius and Rodrigues, the documented fossil record initially was biased toward larger, non-passerine bird species, especially the dodo Raphus cucullatus and solitaire Pezophaps solitaria. This paper provides a synopsis of the fossil Mascarene avifauna, which demonstrates that it was more diverse than previously realised. Therefore, as the islands have suffered severe anthropogenic changes and the fossil record is far from complete, any conclusions based on present avian biogeography must be viewed with caution. Key words: Mauritius, Réunion, Rodrigues, ecological history, biogeography, extinction Introduction ily described or illustrated in ships’ logs and journals, which became the source material for The Mascarene Islands of Mauritius, Réunion popular articles and books and, along with col- and Rodrigues are situated in the south-western lected specimens, enabled monographs such as Indian Ocean (Fig. -
Extinction-Driven Changes in Frugivore Communities on Oceanic Islands
Zurich Open Repository and Archive University of Zurich Main Library Strickhofstrasse 39 CH-8057 Zurich www.zora.uzh.ch Year: 2017 Extinction-driven changes in frugivore communities on oceanic islands Heinen, Julia H ; van Loon, E Emiel ; Hansen, Dennis M ; Kissling, W Daniel Abstract: Global change and human expansion have resulted in many species extinctions worldwide, but the geographic variation and determinants of extinction risk in particular guilds still remain little explored. Here, we quantified insular extinctions of frugivorous vertebrates (including birds, mammals and reptiles) across 74 tropical and subtropical oceanic islands within 20 archipelagos worldwide and investigated extinction in relation to island characteristics (island area, isolation, elevation and climate) and species’ functional traits (body mass, diet and ability to fly). Out of the 74 islands, 33 islands (45%) have records of frugivore extinctions, with one third (mean: 34%, range: 2–100%) of the pre‐extinction frugivore community being lost. Geographic areas with more than 50% loss of pre‐extinction species richness include islands in the Pacific (within Hawaii, Cook Islands and Tonga Islands) and the Indian Ocean (Mascarenes, Seychelles). The proportion of species richness lost from original pre‐extinction communities is highest on small and isolated islands, increases with island elevation, but is unrelated to temperature or precipitation. Large and flightless species had higher extinction probability than small or volant species. Across islands with extinction events, a pronounced downsizing of the frugivore community is observed, with a strong extinction‐driven reduction of mean body mass (mean: 37%, range: –18–100%) and maximum body mass (mean: 51%, range: 0–100%). -

It has become a problem in Pacific regions and is particularly common in dry, coastal woodlands and in secondary forests. It grows on any soil type and will adapt to poor or degraded soils. T. heterophylla regenerates and forms pure monotypic stands. It is an extremely fast growing species and can easily outcompete native and other exotic trees. It bears leaves and branches almost to the base and casts a deep shade under which virtualy no other species can grow. Its thick litter layer may also prevent the growth of native seedlings. view this species on IUCN Red List Species Description T. heterophylla is a small- to medium-size tree attaining a height of 18m and a diameter of 60cm. It has a furrowed bark, and a narrow, columnar crown, with opposite, palmately compound leaves. There are 3-5 leaflets, with blades elliptic to oblanceolate or obovate, 6-16cm long, leathery, acute to blunt at the tip, acute to rounded or oblique at the base; surfaces glabrous; margins entire; petiole 3-12cm long. -

The Spotted Green Pigeon Caloenas Maculata
Hein van Grouw 291 Bull. B.O.C. 2014 134(4) The Spoted Green Pigeon Caloenas maculata: as dead as a Dodo, but what else do we know about it? by Hein van Grouw Received 31 July 2014 Summary.—Described in 1783 and since then re-examined by many notable ornithologists, the single specimen known as the ‘Spoted Green Pigeon’ Caloenas maculata in the collections of the World Museum, Liverpool, has always been a mystery. No-one has ever doubted that it is a pigeon, and many researchers were convinced it was a distinct species. Although its taxonomic status remained unclear, it was ofcially declared extinct by BirdLife International in early 2008. Recent DNA analysis has now revealed that Spoted Green Pigeon can indeed be considered a distinct species within the extended Dodo Raphus cucullatus clade of morphologically very diverse pigeon species. Most members of this clade exhibit terrestrial or semi-terrestrial habits. Further morphological research into this unique specimen, initiated by the World Museum, demonstrates that Spoted Green Pigeon, in contrast to its fellow clade members, may have possessed strongly arboreal habits. The Spoted Green Pigeon Caloenas maculata, represented by a single specimen held in the scientifc collections of the World Museum, Liverpool, has always bafed ornithologists. Although its provenance is unknown, the confusion has mainly centred on whether it is a valid species; that the specimen is a pigeon has never been questioned. Because of its green-glossed plumage and slightly elongated hackles, it is usually assumed to be allied to Nicobar Pigeon C. nicobarica, although they share few other morphological features. -

Between the 5th November 2007 and end of December 2008, forty- two juvenile and adult Pink Pigeons have been transferred from different sites within the park and released there, thus creating the sixth sub-population of the species. In May 2008, the first translocated birds started breeding at this site and made their first nesting attempts. On 16 September 2008, less than a year after the start of the releases, the Lower Black River Gorges celebrated its first on-site fledgling. The squab (pigeon chick) hatched on 1 September and the nest was monitored daily until the bird left the nest on the 16 September. -
