Abstract:
... This article presents the findings of the authors’ study of the mire ecosystem vascular plants of the island of Bolshoy Shantar, which is the largest island in the Shantar archipelago. Bolshoy Shantar Island is an insular ecosystem, the study of which can provide insight into the natural “polygons” of evolution at work. The botanical research was conducted through the application of traditional te ...
phytogeography, etc ; flora; phylogeny; spatial data; species diversity; Show all 5 Subjects
Abstract:
... Existing global regionalization schemes for plants consider the compositional affinities among biotas, but these have not explicitly considered phylogenetic information. Here, we present for the first time, a phytogeographical delineation of the global vascular flora based on species‐level evolutionary relationships. We analysed 8737 820 geographical occurrence records for vascular plants together ...
phytogeography, etc ; Neotropics; Rutaceae; Sapindaceae; flora; indigenous species; Brazil; Show all 7 Subjects
Abstract:
... The Sapindales comprise one of the hallmark orders in the Neotropics, being an important component of forested and open formations, especially in Brazil. In recent decades, there have been many efforts made to unravel the Brazilian flora and its distribution; among them is the Brazilian Flora 2020 Project, the main goal of which was to produce updated monographs about Brazilian plant groups. In th ...

Abstract:
... This work involved materials from the recent and ancient (Holocene and Late Pleistocene) localities of the ornithogenic assemblages of Ural rodent bone remains. The work included the development and trial of criteria for assignment of the temporal dynamics of rodent communities to particular scales based on their comparison against levels of the spatial differences of the recent rodent faunas from ...
phytogeography, etc ; altitude; bedrock; biotopes; phytosociology; species diversity; vegetation; Central Asia; Show all 8 Subjects
Abstract:
... Mountain areas are very often considered to be biodiversity hotspots. Rocks are one of the most unique habitats and serve as a suitable biotope for many endemic and specialized plant species. Here we present the results of the vegetation studies conducted in central and eastern Pamir-Alai and the south-western Tian Shan mountains in 2013‒2019. Based on 334 phytosociological relevés we propose a sy ...

Koch.) trees of the forests of the Gunib plateau (Intramontane limestone Dagestan) are presented. The forests on the plateau are mainly confined to the northern, northeastern, and northwestern slopes; they are found at altitudes of 1400–2170 m a ...

Abstract:
... Thanks to the recently published papers on the classification and diagnostics of soils in Russia, significant progress has been made in theoretical and practical soil science. Here, we outline the principles of the classification of peat soils, which occupy approximately 9% of the soil resources in Russia and annually increasing. As is shown, the organic and mineral parts of peat soils form a gene ...

Abstract:
... Myriopus eulinae (Heliotropiaceae), a new species from northeastern Brazil and associated with the Caatinga, Atlantic Forest, and Caatinga-Cerrado transition phytogeographic domain, is described and illustrated. The species can be morphologically recognized by its discolored leaf blade, lax inflorescences, and strigose to hirsute fruits. We discuss its habitat, flowering and fruiting, taxonomic af ...
phytogeography, etc ; cerrado; geographical distribution; indigenous species; macrophytes; species richness; wetlands; Amazonia; Brazil; Show all 9 Subjects
Abstract:
... Southern Amazonia harbors a wide diversity of aquatic macrophyte species because of its diverse wetland habitats and location in the Amazon-Cerrado transition zone, which spans the two largest biogeographic domains in South America. We investigated the taxonomic diversity of aquatic macrophytes in the region with a focus on endemism, species richness, and life forms. We present new records of aqua ...

Abstract:
... For the first time, a complete inventory and analysis of the taxonomic composition of the flora of the phytogeographic plot “Central Asia” in the M.M. Gryshko National Botanical Garden of the NAS of Ukraine were conducted. The plot “Central Asia” was established in 1953 for the directed introduction and naturalization of plants from Central Asia. Over 1,000 plant species have been tested here duri ...

Abstract:
... The fossil record of Lythrum is scarce and every new find brings an extra piece of the puzzle to the obscure phytogeographic history of this genus. Lythrum pollen is unique and has the potential to be recognized in palynological assemblages. Therefore, the few pre-Holocene fossil records are all pollen described from North America, Russia, and Europe. The European records are both most numerous an ...

Abstract:
... BACKGROUND: Some insects are harmful to humans, plants and animals, but some of them can also be a source of proteins, fats, vitamins and minerals and be of therapeutic value. The therapeutic potential requires that medicinal insects and their derived products need to be scrutinized. This study highlights the indigenous knowledge related to their use of medicinal insects in peri-urban and urban ar ...
