Fuscoporia caymanensis sp. nov. (Basidiomycota, Hymenochaetaceae), a new species from tropical America

Fuscoporia caymanensis sp. nov. is described from tropical America. It is characterized by perennial, extensive, resupinate to indistinctly effused-reflexed basidiomata; a very thin to almost absent subiculum; multi-layered tubes with a black line between each layer; a dimitic hyphal system with&...

Challenge to molecular archaeology—Sediments contaminated by allochthonous animal proteins

In this work we proposed a novel methodological approach to detect and differentiate between cooked and uncooked animal meat protein in archaeological samples. We tested two groups of materials: ceramic dated to the early medieval period (9th–10th centuries CE) and soil samples collecte...

The cuticles of (?) thylacocephalan arthropod from the Basal Choteč Event (Choteč Formation, Eifelian; Barrandian area, Czech Republic)

Small fragments of phosphatic cuticle have been observed in dark limestone of the early Eifelian age (Choteč Formation) in the interval of the Basal Choteč Event. The cuticle is two-layered, primarily folded, with a chamber between outer and inner walls. Fragments likely represent ...

Problematic sclerites Eurytholia from the Lower and Middle Devonian of the Czech Republic

Problematic phosphatic sclerites Eurytholia are reported for the first time from the Middle Devonian. Unequivocal sclerites were observed in limestones of Emsian to late Eifelian age in six localities of the Barrandian area of the Central Bohemia of the Czech Republic. Formerly observed...

Dendritic microborings in brachiopod shells from the Silurian of the Barrandian area, Czech Republic

Four types of dendritic microborings preserved as natural casts were observed on the surfaces of brachiopod shells from the Silurian in Central Bohemia: Rhopalondendrina jakubinka isp. nov., ? Clionolithes isp., and an indeterminate dendrinid are of Llandovery (Aeronian) age, Clionolithes amoebae...

Uniformity of tropical micromorphic brachiopods from the Lower Devonian: lingulates from the section Compte-I of Spanish Central Pyrenees.

Lingulate brachiopods of the Lochkovian and Pragian age from the Compte-I section in the Spanish Central Pyrenees are described to elucidate the evolutionary history of this brachiopod group. Precise bio- and chronostratigraphic position of the brachiopod association is supported by the cono...

Methods for monitoring alpine plant phenology: a pilot study in the line Creek Plateau research natural area, USA

Alpine plant phenological traits are studied and several hypotheses about their latitudinal variation are tested within a comparative research project, which is being conducted on groups od plant species for which relationschips are inferred from available phylogenies. The study sites for th...

Lingulate brachiopods of Tremadocian age from the abandoned Gabriela Mine (Krušná Hora, Central Bohemia, Czech Republic)

Lingulate brachiopods are described from a lithic sandstone referred to the upper part of the Třenice Formation. Loose blocks were sampled from a dump of abandoned Gabriela Mine in Krušná Hora Hill near Beroun, Central Bohemia. Apart of the Acrotreta aff. grandis Klouček, 1919,...

Trilobite assemblage of Calceola-bearing beds in Acanthopyge Limestone (Choteč formation, middle Devonian, Eifelian, Prague Basin, the Czech republic)

The trilobite assemblage of Calceola-bearing beds in the upper part of Acanthopyge Limestone (Choteč Formation, Eifelian) in the Koněprusy area, the Czech Republic, is described. Together with occurrence of Calceola, it indicates absence of significant palaeogeographic barriers restricting the distrib...

Rhynchonelliform brachiopods and trilobites of the ‘upper dark interval’ in the Koněprusy Area (Devonian, Eifelian, Kačák Event; the Czech Republic)

The dark pelbiodetrital limestone beds of the ‘upper dark interval’ in the Koněprusy area, Central Bohemia, the Czech Republic, the assumed manifestation of the Kačák Event in this area, yielded a moderately diverse faunule of rhynchonelliform brachiopods and trilobites. In total, 15 sp...

The influence of load on the transformers on the size of their own losses

We examined the value of targeted molecular screening for the identification of uterine anaplastic lymphoma kinase (ALK)- rearranged mesenchymal tumors, including ALK immunohistochemistry followed by molecular genetic testing, in all uterine leiomyosarcomas and STUMPs (smooth muscle tumors of uncertain...

Recovery of the Velky Bolevecky Pond (Plzen, Czech Republic) via biomanipulation - Key study for management.

Promotion of successful examples of biomanipulation and long-term monitoring is important for encouragement of similar activities, which are still relatively scarce. A project to improve water quality in the Velky Bolevecky pond (Plzeň, Czech Republic) began in 2006. The main activities in&#...

On Craterocolla and Ditangium (Sebacinales, Basidiomycota)

In the present paper, we select a neotype for Tremella cerasi and prove that it is conspecific with Ditangium insigne (the genus type of Ditangium).We argue that Ditangium should be restored as a correct genus for T. cerasi, while the currently used generic name Craterocolla&#...

First records of Cartilosoma rene-hentic (Polyporales) in the Czech Republic

The recently described polypore Cartilosoma rene-hentic is recorded, described and illustrated from several localities in the Czech Republic for the first time. Its identity was confirmed both based on morphology and by sequencing ITS regions. The species variability and ecology is discussed...
