Cool-season grasses often harbor obligate fungal symbionts from the genus Neotyphodium, and these symbiota can function as a single ecological unit. Previous studies have shown that gene flow in Neotyphodium in Festuca arizonica is low enou...

The fungal species involved in the decomposition of needle litter and their response to intraspecific genetic variation of trees are poorly known. First, we compared the needle decomposition and fungal decomposers underneath eight different...
Geosmithia fungi are highly diverse and consistent bark beetle associates: evidence from their community structure in temperate Europe [0.03%]
欧洲温带地区树木天牛社群结构中《Geosmithia》真菌的高度多样性和一致性分布规律的研究

Miroslav Kolarík et al.
Geosmithia spp. (Ascomycota: Hypocreales) are little-studied, dry-spored fungi that occur in galleries built by many phloeophagous bark beetles. This study mapped the distribution and environmental preferences of Geosmithia species occurrin...
Bacteria associated with the bleached and cave coral Oculina patagonica [0.03%]
与白化并形成洞穴的巴塔哥尼亚石珊瑚(Oculina patagonica)相关的细菌群落分析

Omry Koren
The relative abundance of bacteria in the mucus and tissues of Oculina patagonica taken from bleached and cave (azooxanthellae) corals was determined by analyses of the 16S rRNA genes from cloned libraries of extracted DNA and from isolated...

Wave-like distribution patterns of gfp-marked Pseudomonas fluorescens along roots of wheat plants grown in two soils [0.03%]
绿色荧光蛋白标记的荧光假单胞菌在小麦根系上的波浪式分布格局及其在两种土壤中的动态变化

Julie M Rose
Experimental studies were carried out on an Antarctic isolate of the heterotrophic nanoflagellate Paraphysomonas imperforata to examine the efficiency of incorporation and remineralization of nitrogen and phosphorus from bacterial prey. Exp...
Population dynamics and diversity of viruses, bacteria and phytoplankton in a shallow eutrophic lake [0.03%]
富营养浅水湖泊中病毒、细菌和浮游植物种群动态及多样性研究

Marjolijn Tijdens et al.
We have studied the temporal variation in viral abundances and community assemblage in the eutrophic Lake Loosdrecht through epifluorescence microscopy and pulsed field gel electrophoresis (PFGE). The virioplankton community was a dynamic c...
Arbuscular mycorrhizal fungi and rhizospheric bacteria diversity along an altitudinal gradient in South American Puna grassland [0.03%]
南美高寒草原车前子内生菌和根系细菌多样性沿海拔梯度的变化

M A Lugo et al.
Rhizospheric soil samples were taken from Puna native grasses along an altitudinal gradient. Biodiversity of arbuscular mycorrhizal fungi (AMF) and associated bacteria was analyzed considering altitude and grasses photosynthetic pathways (m...
Soil fertility and the impact of exotic invasion on microbial communities in Hawaiian forests [0.03%]
