Additions to knowledge of the biodiversity of benthic hydroids (Cnidaria: Hydrozoa) in the Balleny Islands (Antarctica)

2021

The Balleny Islands, an isolated archipelago located 240 km off the coast of Victoria Land (East Antarctica), are separated from the Antarctic continental shelf by waters more than 2000 m deep. The benthic hydroid fauna of these islands is little known, with only 25 species reported so far. The present study contributes to a better knowledge of the benthic hydrozoans inhabiting this archipelago by studying a small collection held at the National Institute of Water and Atmospheric Research Invertebrate Collection at Wellington, New Zealand. Sixteen species of benthic hydroids were found in the collection, belonging to nine families and 12 genera of Leptothecata. Kirchenpaueriidae and Oswalde…

Comparison of sampling methods for semipelagic animals in two deep basins of Lake Saimaa

1996

The efficiency of different methods for sampling semipelagic animals was compared in the deep basins of Lake Paasivesi and Lake Puruvesi of the complex Lake Saimaa, Finland, during 1990–92. Certain semipelagic animals, such as Mysis relicta, amphipods and larvae of Chaoborus flavicans, are important bioindicators of water and benthic quality. However, owing to their high mobility and vertical migrations they are difficult to sample quantitatively with traditional benthic methods.

Parasite assemblages in the Western whip snakeHierophis viridiflavus carbonarius(Colubridae) from southern Italy

2012

AbstractParasite assemblages of the Western whip snakeHierophis viridiflavus carbonariuswere investigated from the Calabria region in southern Italy. A total of 14 parasite taxa including 6 nematodes, 3 acanthocephalans, 2 cestodes, 2 digeneans and a single pentastomid was identified. Within the study area,H. v. carbonariusserves as the final host for seven species of helminths, of which only four (Hexametra quadricornis,Kalicephalus viperae,Paracapillaria sonsinoiandRenifer aniarum) can be considered as snake specialists, while one (Oswaldocruzia filiformis) is shared with other reptiles and amphibians, and two (Paradistomum mutabileandRhabdias fuscovenosa) with lizards. A large proportion…

A new small mammal assemblage from the M013 Terre Rosse fissure filling (Gargano, South-Eastern Italy)

2013

Abstract The taxonomic study of the small mammal assemblage from fissure M013, sampled by a team of the University of Torino during the 2005–2009 excavations in the Dell’Erba Quarry (Apricena, Foggia) is presented. The assemblage includes the Echinosoricinae Apulogalerix cf. pusillus and the Crocidosoricinae ?Lartetium cf. dehmi; the Myomiminae species Stertomys simplex and Stertomys lyrifer; a new genus and species of Cricetodontinae and a single specimen of Hattomys cf. nazarii. Muridae include Mikrotia cf. parva, Mikrotia sp. 1 and a new genus and species of Murinae, phylogenetically related to Mikrotia. The occurrence of the new Murinae, the new Cricetodontinae, the two species of gliri…

Apulogalerix pusillus nov. gen., nov. sp., the small-sized Galericinae (Erinaceidae, Mammalia) from the ‘‘Terre Rosse’’ fissure filling of the Gargan…

2013

Abstract A small moonrat belonging to the Galericini tribe occurs in all the assemblages from the Terre Rosse fissure fillings of the Gargano. It was first mentioned in the pioneering report of Freudenthal and by Butler in his study of the “gigantic” Deinogalerix, and has been quoted with different names several times in faunal lists of the Terre Rosse endemic faunas. Up to date, however, the description of this gymnure has never been achieved. We present here the taxonomical and morphological description of a sample from Fissure Filling F32 that is considered to document the youngest phase of population of the Gargano Paleoarchipelago. The comparisons with genera Galerix, Parasorex and Sch…

New insular taxa from the oldest Terre Rosse fissure filling (Gargano, Southeastern Italy).

2012

A rich amount of fossil remains of a highly diversified vertebrate fauna, known as “Mikrotia fauna”, has been retrieved from the red soil deposits (Terre Rosse) which fill the extensive palaeokarst network that affects the Mesozoic limestone along the north-western slopes of Mount Gargano (Southern Italy). The faunal assemblages reveal a rather complex history of bioevents such as dispersals and extinctions, which occurred when the area was isolated. These reconstructions were based on the materials collected during the seventies and the eighties of the last century. Forty years after its discovery, the Gargano Terre Rosse finally yielded evidence of an older faunal settlement. The peculiar…

UNA LISTA COMENTADA DE LOS SPHINGIDAE DE BOLIVIA (INSECTA: LEPIDOPTERA)

2001

An annotated checklist of the Sphingidae (hawkmoths) of Bolivia is presented. A total of 189 species and subspecies are confirmed. Locality data derived from specimens in the collections of the Department of Entomology of the Natural History Museum Noel Kempff Mercado of Santa Cruz de la Sierra; the Bolivian Collection of Fauna, La Paz; The Natural History Museum, London; and the Carnegie Museum of Natural History, Pittsburgh, are given. A map of these localities and a synoptic discussion of their geography and ecology are also provided. Data on species not represented in these collections are collated from the publications of J. Haxaire and D. Herbin and presented. Diagnostic features to e…

The Protected Species of Lepidoptera in the Oak Forest "Dumbrava Sibiului", Romania

2011

This paper presents the results of research on Lepidoptera fauna of protected forest located Dumbrava Sibiu, near Sibiu city . The theme of the work is included in a study of forest biodiversity and Sibiu Lepidoptera "Dumbrava Sibiului" is part of a school project postdoctoral lasted several months in the forest.
 The first data on Lepidoptera fauna of the forest were reported by Daniel Czekelius collection and analysis covers a total of 45 species collected from the surrounding forest. An important contribution collections were then collected in the Transylvanian Saxons in 1009 and until around 1960 years and have made such an important contribution to knowledge of this group of insec…

Phylogeography of lions (Panthera leossp.) reveals three distinct taxa and a late Pleistocene reduction in genetic diversity

2009

Lions were the most widespread carnivores in the late Pleistocene, ranging from southern Africa to the southern USA, but little is known about the evolutionary relationships among these Pleistocene populations or the dynamics that led to their extinction. Using ancient DNA techniques, we obtained mitochondrial sequences from 52 individuals sampled across the present and former range of lions. Phylogenetic analysis revealed three distinct clusters: (i) modern lions, Panthera leo; (ii) extinct Pleistocene cave lions, which formed a homogeneous population extending from Europe across Beringia (Siberia, Alaska and western Canada); and (iii) extinct American lions, which formed a separate popula…
