Abstract

The paper compares recent and known literature records of mosses from genera Orthotrichum and Nyholmiella in Crimean Peninsula (Ukraine). Field survey was carried out during botanical expedition to Crimean Peninsula in southern Ukraine in 2012. Total 11 species of the genus Orthotrichum and 1 of Nyholmiella were recorded. Among the most interesting taxa, O. lyellii as new species for Crimean Peninsula and O. affine var. bohemicum as new species for Ukraine, could be considered.

Abstract

The paper compares historical and recent records of bryophytes within Orthotrichaceae family recorded in 10 National Nature Reserves of north-eastern part of the Czech Republic. Field survey was carried out in 2013. Altogether 15 species of Orthotrichaceae family were recorded. For data comparison were used the collection efforts of the author, historical and recent herbarium specimens and the available historical literature.

Abstract

The study presents the distribution of the genera Orthotrichum s.l. and Nyholmiella in the phytogeographical district 98. Nízký Jeseník, and follows the project carried out between years 2005 and 2009 in nearby phytogeographical district 97. Hrubý Jeseník. The total number of 57 locations was visited during the year 2015, and 142 samples of mosses were collected. Altogether, 9 species of genus Orthotrichum s.l. and 1 species of the genus Nyholmiella were recently recorded in the studied area. Lists of species and localities are given.

Abstract

Using 35 presence-only data samples and five uncorrelated bioclimatic variables, we made species distribution models (SDMs) for 4 species of critically endangered (CR) liverworts from genus Jungermanniales and Marchantiales (Cephaloziella elegans, Leiocolea heterocolpos, Lophozia wenzelii and Riccia papillosa) using the maximum entropy modelling method (MaxEnt). Since we were modelling CR species, only one model proved to be strong enough to be used in the field. However, SDMs can serve as effective and fast tools for acceleration of the discovery of the rare and endangered species. The final model presented in this study can serve as a guide to future survey expeditions, the conservation of the target species and also to help understand their ecology.

Abstract

The article compares historical and recent records of epiphytic bryophytes from the Orthotrichaceae family in the Hrubý Jeseník Mts. Field survey was carried out between 2005 and 2009. In total, 128 localities were visited. Altogether, 9 species from the Orthotrichum genus, 1 from the Nyholmiella genus, and 2 from the Ulota genus were recently recorded. The following was used for data comparison: records coming from the bryological database of the second author, herbarium specimens (mainly from OP, SUM and private collections), and available historical literature sources.
