One New Endemic Plant Species on Average Per Month in New Caledonia, Including Eight More New Species from Île Art (Belep Islan
CSIRO PUBLISHING Australian Systematic Botany, 2018, 31, 448–480 https://doi.org/10.1071/SB18016 One new endemic plant species on average per month in New Caledonia, including eight more new species from Île Art (Belep Islands), a major micro-hotspot in need of protection Gildas Gâteblé A,G, Laure Barrabé B, Gordon McPherson C, Jérôme Munzinger D, Neil Snow E and Ulf Swenson F AInstitut Agronomique Néo-Calédonien, Equipe ARBOREAL, BP 711, 98810 Mont-Dore, New Caledonia.

The New Caledonian biodiversity hotspot contains many micro-hotspots that exhibit high plant micro- endemism, and that are facing different types and intensities of threats. The Belep archipelago, and especially Île Art, with 24 and 21 respective narrowly endemic species (1 Extinct,21Critically Endangered and 2 Endangered), should be considered as the most sensitive micro-hotspot of plant diversity in New Caledonia because of the high anthropogenic threat of fire. Nano-hotspots could also be defined for the low forest remnants of the southern and northern plateaus of Île Art. With an average rate of more than one new species described for New Caledonia each month since January 2000 and five new endemics for the Belep archipelago since 2009, the state of knowledge of the flora is steadily improving. -

Reptile species richness in South Africa (darker shades indicate higher richness), with the current protected area network indicated by the grey shaded polygons and the protected area expansion network indicated by black polygon outlines. 3 Appendix S1. Protocol for Measuring Protection Level for South African Reptiles The following process was applied to measure the level of protection for each species, using the interpreted distributions for the species (see main text). We evaluated the effectiveness of South Africa’s protected area network in ensuring that minimum viable populations of reptiles are protected. We set a conservation target for protection of at least 10 fragments of protected habitat, each with areas greater than 10 km2 (1000 ha) for a total of 100 km2 for each species. The fragment size was considered to be the minimum area that would support viable populations, with the total area considered to be the total area needed to safeguard the species survival into the future. The interpreted distributions for each species were then intersected with South Africa’s protected area network (Government of South Africa, 2010). -

Poison Dart Frogs of the Genus Phyllobates Secrete Lipophilic Alkaloid
Cloning and Sequence Analysis of the Voltage-Gated Muscle Na + Channel from the Poison Dart Frog Phyllobates aurotaenia . Castano, S. 1, 2 , Frezza, L. 1, Labro, A. 3, Fierro, L. 2, Bezanilla, F. 1, Correa, A.M. 1 1The University of Chicago, Chicago, IL, USA. 1Grupo de Biología Integrativa (BINTE), Escuela de Ciencias Básicas, Facultad de Salud, Universidad del Valle. 3University of Antwerp, Wilrijk, Belgium. Poison dart frogs of the genus Phyllobates secrete lipophilic alkaloid toxins through their skin that were used by Colombian Amerindians to poison the tips of blowdarts. One of the most potent toxins identified is batrachotoxin (BTX) which is an activator of voltage-gated Na+ channels. BTX causes sustained opening of these channels by shifting the voltage-dependent activation to more hyperpolarized potentials and by disabling both fast and slow inactivation. It also alters pore conductance and selectivity. Endogenous Na+ channels of the poison arrow frog have been proposed to be insensitive to lethal amounts of BTX. In this project we aim to identify what confers BTX insensitivity to Na+ channels of the host frog Phyllobates aurotaenia, therefore we cloned its skeletal muscle NaV channel. Total RNA from skeletal muscle of Phyllobates aurotaenia was isolated and cDNA was obtained with degenerate primers. The 1819 amino acids sequence shares 72% sequence identity with the rat Na+ channel NaV1.4, and 73% with that of the snake Thamnophis sirtalis. The TMs are extremely well conserved (87%) with absolute conservation of S4 in all domains. The N-and C- termini as well as the cytoplasmic linkers between domains are more divergent. -

E-mail: [email protected] Abstract A new species, Acropogon mesophilus Munzinger & Gâteblé (Malvaceae, Sterculioideae), is described from New Caledo- nia. This species is endemic to non-ultramafic areas, along the southwestern coast of Grande-Terre. The species has large leaves, widely ovate to ovate, and entire, and might be confused with only two other endemic species, namely A. bullatus (Pancher & Sebert) Morat and A. veillonii Morat. However, A. mesophilus differs from the other two species most evidently by its leaves 3-nerved, flat, and with truncate to rounded bases, versus leaves 5-nerved, bullate, and with cordate bases. A line drawing and color photos are provided for the new species, along with a discussion of its morphological affinities and a preliminary risk of extinction assessment of Endangered. Keywords: Acropogon, Malvaceae, mesic forest, New Caledonia, new species, Sterculioideae, taxonomy, threatened species Introduction Forests in New Caledonia are currently more or less arbitrarily divided into sclerophyll (or dry) and dense humid forests, the latter being further separated into two main types depending on edaphic conditions, i.e., on ultramafic versus non-ultramafic substrate (Jaffré et al. -

A Review of Chemical Defense in Poison Frogs (Dendrobatidae): Ecology, Pharmacokinetics, and Autoresistance
Chapter 21 A Review of Chemical Defense in Poison Frogs (Dendrobatidae): Ecology, Pharmacokinetics, and Autoresistance Juan C. Santos , Rebecca D. Tarvin , and Lauren A. O’Connell 21.1 Introduction Chemical defense has evolved multiple times in nearly every major group of life, from snakes and insects to bacteria and plants (Mebs 2002 ). However, among land vertebrates, chemical defenses are restricted to a few monophyletic groups (i.e., clades). Most of these are amphibians and snakes, but a few rare origins (e.g., Pitohui birds) have stimulated research on acquired chemical defenses (Dumbacher et al. 1992 ). Selective pressures that lead to defense are usually associated with an organ- ism’s limited ability to escape predation or conspicuous behaviors and phenotypes that increase detectability by predators (e.g., diurnality or mating calls) (Speed and Ruxton 2005 ). Defended organisms frequently evolve warning signals to advertise their defense, a phenomenon known as aposematism (Mappes et al. 2005 ). Warning signals such as conspicuous coloration unambiguously inform predators that there will be a substantial cost if they proceed with attack or consumption of the defended prey (Mappes et al. 2005 ). However, aposematism is likely more complex than the simple pairing of signal and defense, encompassing a series of traits (i.e., the apose- matic syndrome) that alter morphology, physiology, and behavior (Mappes and J.
