Establishing a Protocol to Measure Tetrodotoxin (TTX) Levels in Small-Bodied Newts (Genus Lissotriton) in Western Europe
Establishing a protocol to measure tetrodotoxin (TTX) levels in small-bodied newts (genus Lissotriton) in western Europe Rosa Wagstaff This Thesis is Submitted in Fulfilment of the Requirements for the Degree of MSc by Research School of Science, Engineering and Environment University of Salford, Salford, UK March 2021 1 Abstract Tetrodotoxin (TTX) is a defence toxin most commonly found in marine organisms, and amphibians are the only land vertebrates (tetrapods) which are known to produce TTX. However, the origin of TTX in amphibians remains largely unknown, and our knowledge about the existence and distribution of TTX across taxa and populations is very incomplete. The present study summarises our knowledge of TTX in amphibians, and describes a series of experiments to determine whether TTX can be detected in newts (genus Lissotriton and Icthyosaura) across north-eastern Europe. The study was based on eggs and fresh roadkills collected in England, Scotland, Wales and France. The roadkill samples were collected at a site inhabited by both Lissotriton vulgaris and L. helveticus, and species identification was attempted using mtDNA sequencing. An initial set of TTX detection experiments considered all samples, and trialled alternative extraction protocols before employing HPLC/UV/Vis spectrometry. While strong candidate peaks for TTX were identified in some samples, the employed approach was not sufficiently sensitive to unambiguously demonstrate its presence. Three of the adult newts collected from England were further tested for TTX using liquid chromatography and high-resolution mass spectrometry. No tetrodotoxin was detected in any of the newts that were tested. The findings are discussed in light of the observed constraints by the protocols used and should serve as a useful basis for future studies on the presence of TTX in European amphibians. -
A New Dimension of Current Biodiversity Loss?

Abstract: Current loss of global biodiversity is dramatic. At present, species extinctions are scattered across the evolutionary tree of life, thus affecting numerous species. However, extinctions of entire species-rich evolutionary lineages have not been documented among the current biodiversity loss. Allocation of IUCN Red List categories to all 74 described species of the Neotropical frog genus Atelopus (harlequin frogs) revealed that nowadays two and 61 species are in the categories Extinct and Critically Endangered (which means nearly extinct), respectively. This is the first evidence that presently an entire species-rich evolutionary lineage of animals is next to extinction and may shift current biodiversity loss into a new dimension. Key words: Amphibia, Bufonidae, Atelopus, Neotropics, IUCN Red List categories, extinction. Resumen: "Una nueva dimensión de pérdida de biodiversidad actual?". La pérdida actual de biodiversidad es dramática. Actualmente, las extinciones de especies están dispersas por todo el árbol evolutivo de la vida, afectando por consiguiente a numerosas especies. -

Extinction Risk and Population Declines in Amphibians
Extinction Risk and Population Declines in Amphibians Jon Bielby Imperial College London, Division of Biology, A thesis submitted for the degree of Doctor of Philosophy at Imperial College London – May 2008 1 Thesis abstract This thesis is about understanding the processes that explain the patterns of extinction risk and declines that we see in amphibians, how we can use that understanding to set conservation priorities, and how we can convert those priorities into practical, hands-on research and management. In particular, I focus on the threat posed by the emerging infectious disease, chytridiomycosis, which is caused by the chytrid fungus, Batrachochytrium dendrobatidis ( Bd ). Amphibians display a non-random pattern of extinction risk, both taxonomically and geographically. In chapter two I investigate the mechanism behind the observed taxonomic selectivity and find that it is due to species biology rather than heterogeneity in either threat intensity or conservation knowledge. In chapter three I determine which biological and environmental traits are important in rendering a species susceptible to declines, focussing on susceptibility to Bd . I found that restricted range, high elevation species with an aquatic life-stage are more likely to have suffered a decline. Using these traits, I predict species and locations that may be susceptible in the future, and which should therefore be a high priority for amphibian research and conservation. 2 The use of predictive models to set conservation priorities relies on the accuracy of the modelling technique used. In chapter four I compare the predictive performance of both phylogenetic and nonphylogenetic regression and decision trees, and assess the suitability of each technique. -

Batrachochytrium Dendrobatidis Global Invasive Species Database
FULL ACCOUNT FOR: Batrachochytrium dendrobatidis Batrachochytrium dendrobatidis System: Undefined Kingdom Phylum Class Order Family Fungi Chytridiomycota Chytridiomycetes Chytridiales Common name chytrid frog fungi (English), Chytrid-Pilz (German), chytridiomycosis (English), frog chytrid fungus (English) Synonym Similar species Summary Batrachochytrium dendrobatidis is a non-hyphal parasitic chytrid fungus that has been associated with population declines in endemic amphibian species in upland montane rain forests in Australia and Panama. It causes cutaneous mycosis (fungal infection of the skin), or more specifically chytridiomycosis, in wild and captive amphibians. First described in 1998, the fungus is the only chytrid known to parasitise vertebrates. B. dendrobatidis can remain viable in the environment (especially aquatic environments) for weeks on its own, and may persist in latent infections. view this species on IUCN Red List Global Invasive Species Database (GISD) 2021. Species profile Batrachochytrium Pag. 1 dendrobatidis. Available from: http://www.iucngisd.org/gisd/species.php?sc=123 [Accessed 06 October 2021] FULL ACCOUNT FOR: Batrachochytrium dendrobatidis Species Description Fungal Morphology: Batrachochytrium dendrobatidis is a zoosporic chytrid fungus that causes chytridiomycosis (a fungal infection of the skin) in amphibians and grows solely within keratinised cells. Diagnosis is by identification of characteristic intracellular flask-shaped sporangia (spore containing bodies) and septate thalli. The fungus grows in the superficial keratinised layers of the epidermis (known as the stratum corneum and stratum granulosum). The normal thickness of the stratum corneum is between 2µm to 5µm, but a heavy infection by the chytrid parasite may cause it to thicken to up to 60 µm. The fungus also infects the mouthparts of tadpoles (which are keratinised) but does not infect the epidermis of tadpoles (which lacks keratin). -

Here, we report historical sightings and recent extensive surveys conducted by us in three historical localities where the Quimbaya toad was reported. The last observations of the Quimbaya toad were between 1994 and 1997 in these three localities. Although we conducted three extensive surveys during several years (2003–2004, 2010–2011, and 2011–2012), we could not detect any individual, nor eggs or tadpoles. We discuss some potential drivers of population declines and suggest that this species be declared as Possibly Extinct. -

Universidade de São Paulo, 05508-090, São Paulo, SP, Brazil. 3Corresponding author. E-mail: [email protected] The Neotropical toads of the genus Atelopus are among the most imperiled of all amphibians (La Marca et al. 2005; Gonzalez-Maya et al. 2013; McCaffery et al. 2015). Nowadays, at least 90% of the 93 listed species are threatened and more than 77% are Critically Endangered (McCaffery et al. 2015; IUCN 2016). Colombia has 44 described species of Atelopus (Frost 2017), two of these are categorized as extinct (EX) by the IUCN (2016): A. ignescens and A. longirostris, although they were recently re-discovered in Ecuador (Tapia et al. 2017), 34 as critical endangered (CR), four as endangered (EN), two as vulnerable (VU), one species has data deficient (DD) and another one has not been evaluated. Atelopus subornatus Werner, 1899, is an endemic Colombian harlequin toad described from 2300 to 2800 m.a.s.l in the municipalities of Sibaté (Alto de Sibaté and Agua Bonita) and Fusagasuga (above Fusagasuga and Tierra Negra), in Cundinamarca (Fig.
