We investigated the effects of different doses (0, 2.5, 25 and 250 µg) of the neuropeptide arginine vasotocin (AVT) on the calling characteristics of the grey treefrog in a chorus in its natural habitat. AVT changed some call characteristics known to influence social behaviour in grey treefrogs. It increased call duration and number of pulses in a call, but not dominant frequency, call rate or ...

The aim of the present work is to assess the potential long-distance effect of a high-speed railway line on the distribution of the European tree frog (Hyla arborea) in eastern France by combining graph-based analysis and species distribution models. This combination is a way to integrate patch-level connectivity metrics on different scales into a predictive model. The approach used is put in p...

Amphibian population declines around the world are associated with invasive species, pesticides, pathogens, habitat destruction, or a combination of factors. Because contamination is widespread, it represents a relevant environmental stress that can affect the ability of organisms to deal with other factors present in the environment. We examined the effects of the insecticide malathion, larger...

Polydesmidae are represented in Taiwan by seven species in two genera. Neither of the genera is endemic to Taiwan, but six of the species are, including five new: Nipponesmus minorsp. n., Epanerchodus bispinosussp. n., Epanerchodus curtigonopussp. n., Epanerchodus flagellifersp. n. and Epanerchodus pinguissp. n. In addition, the diagnosis of the hitherto enigmatic genus Nipponesmus Chamberlin &...

The mechanism of high-level resistance to vancomycin in enterococci consists of the synthesis of peptidoglycan terminating in D-alanyl-D-lactate instead of the usual D-alanyl-D-alanine. This alternate cell wall biosynthesis pathway is ensured by the collective actions of three enzymes: VanH, VanA, and VanX. The origin of this resistance mechanism is unknown. We have cloned three genes encoding ...

BACKGROUND Cockroaches are found as the most common urban pests of tropical countries, prompting economic and serious health risk problem for humans by carrying microbes and allergens, acting as vector for various pathogens of diseases. The present study was conducted from April 2013 to March 2014 in various human dwelling localities of urban area of district Lahore, Pakistan. METHODS Cockroa...

The cranial and postcranial anatomy of the basal hadrosaurid dinosaur Eotrachodon orientalis, from the uppermost Santonian of southern Appalachia (southeastern U.S.A.), is described in detail. This animal is the only known pre-Campanian non-lambeosaurine hadrosaurid, and the most complete hadrosauroid known from Appalachia. E. orientalis possesses a mosaic of plesiomorphic and derived character...

The Molecules Editorial Office wishes to make the following erratum to this paper [1]. There is a misspelling in the title of “Antioxidant, Lipoxygenase and Histone Deacetylase Inhibitory Activities of Acridocarbus orientalis from Al Ain and Oman.” The correct title should be “Antioxidant, Lipoxygenase and Histone Deacetylase Inhibitory Activities of Acridocarpus orientalis from Al Ain and Oman...

In the present study, a novel antigenic protein expressed in the piroplasm stage of Theileria orientalis was characterized. A 4,707 bp genomic fragment amplified by PCR contained two open reading frames (ORFs). The deduced amino acid sequence of the first ORF showed significantly high similarlity to the ubiquitin carboxy terminal hydrolases/proteases while the second ORF (To ORF2) showed homolo...
