A new locality of the taxon from genus Potentilla , endemic to flora Russia and Kazakhstan, was discovered in Eastern Europe. Previously, P. × angarensis recorded for European part based on collections Moscow Region Republic Udmurtia. The paper reports first record this hybrid Oka-Don Lowland, which found northeast Voronezh Region. main morphological characters hybridogenic taxon, dis...

In the continuation of studies on Alternaria species, some 500 isolates were obtained from seeds, soil and plant parts from various localities of Iran. Prior to morphological examination, pure cultures were obtained by single conidium and single chain methods. Descriptions for each taxon are based on cultures developed on potato carrot agar. Inoculated plates were incubated at 23-25°C under a c...

quercus persica and pistacia mutica are two known and prevalent forest trees of baneh and marivan from kurdistan province (w iran). thirty-five fungal isolates were obtained from 50 bark samples of q. persica collected in sept. and mar. 2010–11. the aim of this study was to identify fungi associated with oak trees of kurdistan province. based on morphological features and authentic keys (ellis ...

Background We coin the term "taxon expeditions" for citizen scientists' field courses to carry out publishable taxonomic work in close association with trained taxonomists. New information During the first-ever taxon expedition, in Maliau Basin Studies Centre, Sabah, Malaysian Borneo, the participants sampled leaf litter beetles from lowland dipterocarp forest using the Winkler apparatus. The...

The genus Tachuris Lafresnaye, 1836 was recently placed in a new monotypic family rank taxon, Tachurididae Ohlson, Irestedt, Ericson & Fjeldså, 2013, proposed to reflect the molecular recovery of this taxon as an independent lineage related to Tyrannidae Vigors, 1825 and Rhynchocyclidae Berlepsch, 1907 (Ohlson et al. 2013). The purpose of this paper is to propose a correction in the original sp...

MOTIVATION Abundance profiling (also called 'phylogenetic profiling') is a crucial step in understanding the diversity of a metagenomic sample, and one of the basic techniques used for this is taxonomic identification of the metagenomic reads. RESULTS We present taxon identification and phylogenetic profiling (TIPP), a new marker-based taxon identification and abundance profiling method. TIPP...

Conodonts are the most important fossil remains from the largest Phanerozoic extinction as well as the mass extinction of the late Paleozoic and could be used for exact dating during this period. Triassic deposits located in the Elikah Formation contain exposures in most of the Alborz sections as well as the Zal section in northwestern Iran. In this study, the Elikah Formation was investigated ...

A new genus and new species of the pselaphine tribe Batrisini, Zopherobatrus tianmingyii Yin & Li gen. et sp. n., is described based on material collected from a cave in Guizhou, southwestern China. The new taxon exhibits a typical suite of morphological adaptations to life in caves, and represents a third genus of the cave-inhabiting Pselaphinae in China.

As coral bleaching events become more frequent and intense, our ability to predict and mitigate future events depends upon our capacity to interpret patterns within previous episodes. Responses to thermal stress vary among coral species; however the diversity of coral assemblages, environmental conditions, assessment protocols, and severity criteria applied in the global effort to document blea...

Archaeoditomotarsus crassitylus, gen. and sp. nov. of Acanthosomatidae (Ditomotarsinae: Ditomotarsini), is described and illustrated. The biogeography of the new taxon is discussed and a key to the Chilean genera of Ditomotarsinae is included.
