A redescription of Protoopalina pingi Nie, 1935 is presented in this paper to complete Nie's description at both light and scanning electron microscope levels. These organisms were collected from the recta of the frogs Hylarana guentheri Boulenger, 1882 and Pelophylax nigromaculatus Hallowell, 1861 from Jialing River, Sichuan Province and Honghu Lake, Hubei Province, respectively, in China. Thi...

This paper aims to study the characteristics of greenhouse gas (GHG) emissions from heavy-duty trucks in the Beijing-Tianjin-Hebei (BTH) region, which is located in Northern China. The multiyear emissions of GHG (CO2, CH4 and N2O) from heavy-duty trucks fueled by diesel and natural gas during the period of 2006–2015 were compared and analyzed. The results show that the GHG emissions from heavy-...

Processes of regeneration and reorganization are analyzed in two sabellid polychaetes. Abdominal pieces of Branchiomma nigromaculata, during head regeneration, ordinarily reorganize only a fraction of the number of segments typical of the thorax. In pieces transected in the vertical plane, but obliquely with regard to the main axis of the worm, the extent of reorganization is greatly enhanced. ...

A rare basidiomycete Quambalaria cyanescens, documented so far on various substrates worldwide, was isolated from the skin of edible frog (Pelophylax esculentus) captured in South Banat. The fungal identification based sequencing ITS region and BLAST analyses. presence Q. cyanescens amphibian microbiome is not only first finding this fungus Serbia but also recording new ecological habitat for s...
