Abstract:

Grassland degradation is a major ecological problem at present, leading to changes in the grassland environment and the soil microbial community. Here, based on full-length 16S rRNA gene sequencing, we highlight the importance of small-scale environmental changes on the Qinghai-Tibet Plateau grassland for the composition and assembly processes of abundant and rare bacterial taxa. The results showed that grassland vegetation coverage affected the taxonomic and phylogenetic composition of rare bacterial taxa more than abundant bacterial taxa.

Unraveling how microbial interactions and assembly process regulate the rhizosphere abundant and rare taxa is crucial for determining how species diversity affects rhizosphere microbiological functions.

The taxonomic composition was significantly distinct between the fungal and bacterial abundant and rare taxa. Additionally, the rare taxa of bacteria and fungi exhibited higher diversit

Anthropogenic disturbances have a negative impact on lake ecosystems, such as water environmental degradation.

Microorganisms play essential roles in soil-ecosystem multifunctionality.

Rare taxa in Ontario are predominantly peripheral taxa, which have their main ranges outside of Ontario.

Detecting and classifying the plankton in situ to analyze the population diversity and abundance is fundamental for the understanding of marine planktonic ecosystem. However, the features of plankton are subtle, and the distribution of different plankton taxa is extremely imbalanced in the real marine environment, both of which limit the detection and classification performance of them while implementing the advanced recognition models, especially for the rare taxa.

Abstract:

Environmental contextMicrobes play key roles in controlling acidification and metal toxicity in coastal acid-sulfate soils. We characterised the time-dependent metabolic activities of abundant and rare taxa in acidifying tidal wetlands and showed that rare taxa exhibiting higher activity may exert significant influence on iron- and sulfur-cycling. Our findings yield new insights into the drivers and timing of iron- and sulfur-cycling in coastal acid-sulfate systems. AbstractTidal inundation has been trialled as a remediation strategy for coastal acid-sulfate soil (CASS) environments. Microbial

RESUME. Diversité floristique des suberaies du Parc National de Tlemcen (Algérie). L’analyse de la diversité floristique des forêts de Hafir Zariffet a révélé l’existence de 211 taxons appartenant à 65 familles et 164 genres. Le nombre de taxons endémiques et/ou rares inventoriés comporte: 1 endémique algérien,7 algéro-marocains, 11 ibéro-algéro-marocains, 7 sont endémiques d’Afrique du Nord et 11 sont des endémiques d’Afrique du Nord et de la Péninsule ibérique. Le nombre des taxons rares s’élève à 26 dont 9 sont en même temps rares est menacés. Des efforts urgents de protection doivent êtres

Abstract:

Analysis of the faunistic composition of Zooplankton in two reservoirs for watersupply nearby Kragujevac indicated a relatively great diversity. Qualitative analysis of Zooplankton composition in the Grosnica reservoir demonstrated the presence of 105 laxa, whereas somewhat fewer taxa (99) were recorded in the Gruza reservoir. Most of the taxa recorded in both reservoirs are cosmopolitan organisms. Small number of recorded taxa have been rarely registered in the territory of Serbia till present. The following species from the group of Rotatoria can be mentioned as being probably found for the

Abstract:

The review of recent researches regarding the in vitro culture of 30 endangered Dianthus taxa is presented in this paper. Various in vitro protocols developed for selected rare and threatened Dianthus taxa are analysed in order to provide a useful synthesis of the data obtained with the main principles, techniques and recommendations for futher research and practice. The recapitulated data presented in this review can be used as a tool for the micropropagation of other endangered Dianthus taxa, enabling their propagation and obtaining a sufficient amount of plants for reintroduction.

Abstract:

Additions to the flora of the Republic of Altai are given. For the first time for the Republic of Altai, Potamogeton maackianus, Potamogeton rutilus, Elatine hydropiper were detected; the findings of two pondweed hybrids Potamogeton × nitens and Potamogeton × cognatus were confirmed with identification characteristics. Information is provided on the general distribution of all taxa. Issues of rarity and conservation status of species discovered for the first time in the region are discussed. Due to its rarity throughout its range, including Siberia, Elatine hydropiper is recommended for involv
