The widely observed positive relationship between plant diversity and ecosystem functioning is thought to be substantially driven by complementary resource use of plant species.

Mycorrhizal fungi can re-distribute nutrients among plants through formation of underground common mycorrhizal networks and therefore may alter interspecific plant competition. However, the effect of ectomycorrhizal EM fungi on interspecific plant competition in subtropical forests is poorly understood. In this study, we investigated the effects of EM fungal identity and diversity on the outcome of interspecific competition of plant species in relation to different successional stages in a Chinese subtropical forest. This study selected four woody plant species, i.

Plant—mycorrhizal fungal interactions are ubiquitous in forest ecosystems. While ectomycorrhizal plants and their fungi generally dominate temperate forests, arbuscular mycorrhizal symbiosis is common in the tropics. In subtropical regions, however, ectomycorrhizal and arbuscular mycorrhizal plants co-occur at comparable abundances in single forests, presumably generating complex community structures of root-associated fungi. To reveal root-associated fungal community structure in a mixed forest of ectomycorrhizal and arbuscular mycorrhizal plants, we conducted a massively-parallel pyrosequencing analysis, targeting fungi in the roots of 36 plant species that co-occur in a subtropical forest.

INTRODUCTION

Metrics details. Establishing mixed plantations is an effective way to improve soil fertility and increase forest productivity. Arbuscular mycorrhizal AM fungi are obligate symbiotic fungi that can promote mineral nutrient absorption and regulate intraspecific and interspecific competition in plants. However, the effects of mixed plantations on the community structure and abundance of AM fungi are still unclear. The objective of this study is to compare the differential responses of the root and rhizosphere soil AM fungal communities of Juglans mandshurica to long-term mixed plantation management. Compared with that in the pure plantation, the relative abundance of Glomus was higher in the mixed plantation. The relative abundances of Diversispora and an unidentified genus of Glomeromycetes were higher and lower in the pure plantation, respectively.

Стоя над Хейлом и стараясь унять дрожь, Сьюзан услышала приближающиеся шаги и медленно обернулась. В проломе стены возникла фигура Стратмора. Он был бледен и еле дышал. Увидев тело Хейла, Стратмор вздрогнул от ужаса. - О Боже! - воскликнул.  - Что случилось.

Не спуская со Стратмора ледяного взгляда, Сьюзан сделала шаг вперед и протянула к нему руку с зажатым в ней предметом. Стратмор был почти уверен, что в руке Сьюзан сжимала беретту, нацеленную ему в живот, но пистолет лежал на полу, стиснутый в пальцах Хейла. Предмет, который она держала, был гораздо меньшего размера. Стратмор опустил глаза и тут же все понял. Время для него остановилось. Он услышал, как стучит его сердце. Человек, в течение многих лет одерживавший победу над опаснейшими противниками, в одно мгновение потерпел поражение.

Наконец он заговорил - спокойно, тихо и даже печально: - Нет, Грег, извини. Я не могу тебя отпустить. Хейл даже замер от неожиданности.

Фонтейн пришел к выводу, что Стратмор в полном порядке, что он трудится на сто десять процентов, все так же хитер, умен и в высшей степени лоялен, впрочем - как. Лучшее, что мог сделать директор, - не мешать ему работать и наблюдать за тем, как коммандер творит свое чудо.

Скажите, что вы от. Попросите его передать паспорт Росио. Росио сопровождает мистера Густафсона сегодня вечером. Она непременно передаст ему паспорт.

В приемной было темно, свет проникал только сквозь приоткрытую дверь кабинета Мидж. Голоса не стихали. Он прислушался. Голоса звучали возбужденно. - Мидж.

В Третьем узле виднелось голубоватое сияние: терминалы по-прежнему работали; они обеспечивали функционирование ТРАНСТЕКСТА, поэтому на них поступало аварийное питание. Сьюзан просунула в щель ногу в туфле Феррагамо и усилила нажим. Дверь подалась. Стратмор сменил положение. Вцепившись в левую створку, он тянул ее на себя, Сьюзан толкала правую створку в противоположном направлении.

У нее был такой вид, словно она только что увидела призрак. - Джабба! - Соши задыхалась.

    Biological invasions can have various impacts on the diversity of important microbial mutualists such as mycorrhizal fungi, but few studies have tested whether the effects of invasions on mycorrhizal diversity are consistent across spatial gradients.
