JARG (Jersey Amphibian & Reptile Group) www.groups.arguk.org/jarg Slow Worm Anguis fragilis The slow worm is found throughout Jersey, with the majority of records being received from the South West of the Island; possibly due to under recording elsewhere. Slow worms look snake like, but are in fact a legless lizard; they can shed their tails and can also blink like other lizards do. Size – Much smaller than grass snakes, adults can reach up to 30-45cm, with newly born slow worms measuring just 7- 10cm. Features – Slow worms have a polished appearance. Adult females are often light or dark brown and have dark brown sides. They usually also have a thin dark line running along the centre of their backs. Males have a much larger head than females, with no obvious neck. They are also more uniformly coloured than females, and can be found in different shades of brown, bronze or silver. Mature males sometimes have blue spots along their sides. Juveniles in both sexes are golden in colour, with black sides, a black underside and a single black line running the length of the back from the top of the head. Habitat – Slow worms often live in gardens and allotments, where they make use of compost heaps, feeding on small slugs and slow moving invertebrates. In wilder areas of Jersey they can be found in heathland, dunes, wet and dry meadows and occasionally woodland. It is rare to see them basking out in the open as they are well camouflaged, and spend much of their time concealed within burrows, compost heaps or underneath logs, vegetation and loose soil. They can occasionally be seen out and about. Hibernation takes place between October/November-March. Reproduction – Breeding typically takes places in May. Slow worms are ovi-viviparous, meaning, females incubate their young internally, in an egg membrane that breaks shortly after birth. Newborn slow worms are born in the late summer. The slow worm is protected by the Conservation of Wildlife (Jersey) Law 2000. Photo credits: Krissy Le Feuvre .

Numbers of adult males, adult females and juveniles were recorded. Only 3 of 577 Slow-worms captured were found moving or basking on the surface. On days with high capture rates, females and juveniles were more active. The disturbance pattern due to sampling, as well as human activity not related to translocation, affected capture rates. The settling-in period for refugia was not as important as believed. When translocating Slow-worms, it is important to ensure significant capture effort is made throughout the season rather than attempting to choose ‘suitable’ conditions. It is also important to ensure that the density of refugia placement is as high as possible.

November 2018 / Available online: 12. November 2018 / Printed: June 2019 Abstract. Fifteen specimens of the slow worm, Anguis fragilis (two juvenile, five males and eight females), collected in Trabzon and Bursa Provinces, Turkey, were examined for helminths. Anguis fragilis was found to harbour four species of helminths: one species of Digenea, Brachylaemus sp. and three species of Nematoda, Entomelas entomelas, Oxysomatium brevicaudatum and Oswaldocruzia filiformis. In addition, DNA isolated from the Nematodes was analysed with clustal w and blast computer programs for nucleotide sequences. Anguis fragilis from Turkey represents a new host record for Brachylaemus sp. Also, 28s rDNA sequencing of Oxysomatium brevicaudatum and Oswaldocruzia filiformis produced new nucleotide sequences submitted to Genebank (NCBI: National Center for Biotechnology Information). To the knowledge, this is the first DNA analysis of the helminth fauna of Anguis fragilis. Key words: Anguis fragilis, Digenea, Nematoda, DNA sequence, taxonomy.

To the rear of the main hospital buildings are former gardens and much of the centre of the site is occupied by a playing field within which is a bowls square screened by a beech hedge. To the south-west are a sports/recreational centre and football pitch and also older buildings which may have been former stabling/coach houses.

Moscow, Russia Abstract Molecular phylogeny of the reptiles does not accept the basal split of squamates into Iguania and Scleroglossa that is in conflict with morphological evidence. The classical phylogeny of living reptiles places turtles at the base of the tree. Analyses of mitochondrial DNA and nuclear genes join crocodilians with turtles and places squamates at the base of the tree. Alignment of the reptiles’ ITS2s with the ITS2 of chordates has shown a high extent of their similarity in ancient conservative regions with Cephalochordate Branchiostoma floridae, and a less extent of similarity with two Tunicata, Saussurea tunicate, and Rinodina tunicate. We have performed also an alignment of ITS2 segments between the two break points coming into play in 5.8S rRNA maturation of Branchiostoma floridaein pairs with orthologs from different vertebrates where it was possible. A similarity for most taxons fluctuates between about 50 and 70%. This molecular analysis coupled with analysis of phylogenetic trees constructed on a basis of manual alignment, allows us to hypothesize that primitive chordates being the nearest relatives of simplest vertebrates represent the real base of the vertebrate phylogenetic tree.

These ectothermic animals are important in Mediterranean and temperate ecosystems, because they are the prey for many specialist birds (eg, the short-toed eagle, Circaetus gall icus . a snake eater). However, European herpetologists know the identity of few amphibian and reptilian predators. In the recently published "Handbuch der Reptilien und Amphibien Europas", references to predation are scarce and even ignored. However, the ornithological literature contains numerous papers on bird diets, and amphibians and reptiles are frequently cited as bird preys.

Variability in Pulmonary Reduction and Asymmetry in a Serpentiform Lizard: the Sheltopusik, Pseudopus Apodus (Pallas, 1775)
68 (1): 21– 26 © Senckenberg Gesellschaft für Naturforschung, 2018. 19.4.2018 Variability in pulmonary reduction and asymmetry in a serpentiform lizard: The sheltopusik, Pseudopus apodus (Pallas, 1775) Markus Lambertz 1, 2, *, Nils Arenz 1 & Kristina Grommes 1 1 Institut für Zoologie, Rheinische Friedrich-Wilhelms-Universität Bonn, Poppelsdorfer Schloss, 53115 Bonn, Germany — 2 Sektion Herpetolo- gie, Zoologisches Forschungsmuseum Alexander Koenig, Adenauerallee 160, 53113 Bonn, Germany; [email protected] — * Correspond- ing author Accepted 4.ix.2017. Published online at www.senckenberg.de/vertebrate-zoology on 5.4.2018. Editor in charge: Uwe Fritz Abstract Besides snakes, numerous lineages of squamates gave rise to limb-reduced and elongated (serpentiform) species, indicating the evolution- ary success of this modification of the plesiomorphic lizard Bauplan. Concerted with a serpentiform habitus are several morphological adaptations, many of which also concern the structure and arrangement of the viscera, such as frequently a pronounced pulmonary asym- metry in which one lung is reduced or even absent. The European glass lizard or sheltopusik, Pseudopus apodus, is the largest species of the exclusively serpentiform Anguinae. Driven by pre-existing conflicting statements on pulmonary asymmetry, we examined the lungs of 14 sheltopusiks and compared the condition to 11 slow worms (Anguis fragilis). We consistently found the left lung pronouncedly shorter for the slow worm, but indeed a highly variable pulmonary asymmetry between left and right sides in the sheltopusik. This is the first verified case of such variability in pulmonary reduction for any serpentiform squamate and raises several questions about the underlying developmental program for this otherwise taxon-specifically conservative trait.
