Eight different color polymorphisms of the Red-backed Salamander (Plethodon cinereus) have been described throughout its range. Among them, the erythristic phenotype is a mimetic morph with coloration patterns similar to that of toxic Eastern Newt efts (Notophthalmus viridescens). We describe an erythristic morph of P. cinereus collected at Mountain Lake Biological Station, Virginia. To our kno...

In comparison with the large volume of work on lakes located in lowland territories, only scattered information about their ecosystems was available for foothill (low-mountain) areas, both Russia and worldwide. Foothill differ significantly from high-mountain physical biological properties. May, July September 2022, current state Lakes Beloe Kolyvanskoe studied north-west Altai (Russia). The co...

Fig 2. Botfly maggot at early instar. INTRODUCTION Myiasis has largely been considered a rare, exotic condition in the United States. This perception often delays diagnosis, resulting in unnecessary pain and frustration for patients. Here we describe the unusual case of an 11-year-old girl who was parasitized by a cuterebrid botfly after a day trip in August of 2016 to Smith Mountain Lake, Virg...

We studied the isotopic composition of organic matter in the sediments of eight mountain lakes located in the Tatra Mountains (Western Carpathians, Poland). The sediments of the lakes were fine and course detritus gyttja, mud, and sand. The total organic carbon content varied from 0.5 to 53 %. The C/N ratio indicated that in-lake primary production is the major source of the organic matter in t...

We present a 50-year pollen record at near-annual resolution from Gahai Lake in the Qaidam Basin on the northeastern Tibetan Plateau. Chronology of a 22-cm short core was established by Pb and Cs analysis. The pollen results at 0.5 cm intervals show large changes in Artemisia/Chenopodiaceae (A/C) ratios from b0.2 to 0.95 in the last 50 years. High (low) A/C ratios represent increase (decrease) ...

impressive Quaternary lacustrine deposits are present as terrace remnants throughout the Karakoram Mountains, northern Pakistan. They are mainly the result of damming of drainage systems during glacial advances or by catastrophic mass movement deposits. The longevity of most lakes is relatively short, in the order of years to tens of yeaa, but sedimentation rates are extremely high as a consequ...

Polycyclic aromatic hydrocarbons (PAHs) were analysed in liver of fifty-seven individual trout distributed among seven high mountain lakes in Europe and one remote lake in Greenland. In all cases, very similar distributions were observed in which phenanthrene largely predominated and fluoranthene and pyrene were the second major compounds. These distributions were similar to those observed in t...
