Adaptive behaviour of plants, including rapid changes in physiology, gene regulation and defence response, can be altered when linked to neighbouring plants by a mycorrhizal network (MN). Mechanisms underlying the behavioural include fungal colonization MN or interplant communication via transfer nutrients, signals allelochemicals. We focus this review on our new findings ectomycorrhizal ecosystems, also recent advances arbuscular systems. have found that depend environmental cues, identity...
• Spatial analysis was used to explore the distribution of individual species in an ectomycorrhizal (ECM) fungal community address: whether mycorrhizas ECM were patchily distributed, and at what scale; causes this patchiness might be. Ectomycorrhizas extracted from spatially explicit samples surface organic horizons a pine plantation. The number each recorded using morphotyping combined with internal transcribed spacer (ITS) sequencing. Semivariograms, kriging cluster analyses determine both...
Summary Data generated from next generation sequencing ( NGS ) will soon comprise the majority of information about arbuscular mycorrhizal fungal AMF communities. Although these approaches give deeper insight, analysing data involves decisions that can significantly affect results and conclusions. This is particularly true for community studies, because much remains to be known their basic biology genetics. During a workshop in 2013, representatives seven research groups using ecology...
Abstract Microbial ecology has made large advances over the last decade, mostly because of improvements in molecular analysis techniques that have enabled detection and identification progressively larger numbers microbial species. However, determining ecological patterns processes taking place communities microbes remains a significant challenge. Are randomly assembled through dispersal priority effects, or do species interact with each other leading to positive negative associations? For...
While an increasing number of studies indicate that the range, diversity and abundance many wild pollinators has declined, global area pollinator-dependent crops significantly increased over last few decades. Crop pollination to date have mainly focused on either identifying different guilds pollinating various crops, or factors driving spatial changes turnover observed in these communities. The mechanisms temporal stability for ecosystem functioning services, however, remain poorly...
Processes governing the fixation, partitioning, and mineralization of carbon in soils are under increasing scrutiny as we develop a more comprehensive understanding global cycling. Here examined fixation by Douglas-fir seedlings transfer to associated ectomycorrhizal fungi, soil microbes, full-sibling or nonsibling neighbouring seedlings. Stable isotope probing with 99% 13 C-CO2 was applied trace C-labelled photosynthate throughout plants, microbes an experiment designed assess effect...
Large-scale studies that examine the responses of ectomycorrhizal fungi across biogeographic gradients are necessary to assess their role in mediating current and predicted future alterations forest ecosystem processes. We assessed extent environmental filtering on interior Douglas-fir (Pseudotsuga menziesii var. glauca (Beissn.) Franco) fungal communities regional precipitation, temperature, soil fertility dominated forests western Canada. also examined relationships between fine-root...
Summary Separating edaphic impacts on tree distributions from those of climate and geography is notoriously difficult. Aboveground belowground factors play important roles, determining their relative contribution to success will greatly assist in refining predictive models forestry strategies a changing climate. In common glasshouse, seedlings interior Douglas‐fir ( Pseudotsuga menziesii var. glauca ) multiple populations were grown forest soils. Fungicide was applied half the separate soil...
Tree range shifts during geohistorical global change events provide a useful real-world model for how future changes in forest biomes may proceed. In North America, the last deglaciation, distributions of tree taxa varied significantly as regards rate and direction their responses reasons that remain unclear. Local-scale processes such establishment, growth, resilience to environmental stress ultimately influence dynamics. Despite fact interactions between trees soil biota are known...
Abstract Identifying feeding interactions in the fossil record remains a key challenge for paleoecologists. We report rare occurrence of conical, perforative bite mark cervical vertebra an azhdarchid pterosaur, which we identified as juvenile individual Cryodrakon boreas Hone, Habib, and Therrien, 2019 from Campanian Dinosaur Park Formation Alberta, Canada. Based on comparative analysis dentition ecomorphology potential trace makers Formation, well morphology trace, most likely candidate is...
Spaceborne instruments have an irreplaceable role in detecting fundamental vegetation features that link physical properties to ecological theory, but their success depends on our understanding of the complex dynamics control plant spectral properties-a scale-dependent challenge. We explored differences between warmer and cooler areas tree canopies with a ground-based experimental layout consisting spectrometer thermal camera mounted portable crane enabled synergies reflectance measurements...
Temperate forests provide crucial ecosystems services as living sinks for atmospheric carbon (C) and repositories of biodiversity. Applying harvesting at intensities that minimize losses offers one means mitigating global change. However, little is known overstory retention levels best conserve ecosystem in different regional climates, likewise climate changes. To quantify the effect harvest intensity on C stocks biodiversity, we compared five (clearcutting, seedtree retention, 30% patch 60%...
More than 80% of plant species exchange resources with mycorrhizal fungi and these associations impact both partners at multiple scales, from individuals to ecosystems. In total, 172 participants 33 countries 160 institutions met the 10th International Conference on Mycorrhiza (ICOM 10) in city Mérida Yucatan peninsula Mexico – an area famous for its Mayan archaeological sites, cenotes, Chicxulub crater that marks end Cretaceous period. They discussed latest advances research across 125...
Little is known about how community composition in the plant microbiome affected by events life of a plant. For example, when exposed to soil, microbial communities may be an important factor root assembly. We conducted two experiments asking whether microbiota mature plants could determined either timing exposure or priority effects early colonizing microbes. Timing was manipulated through inoculation experiment, where different ages were common soil inoculum. Priority challenging roots...
Summary Mature temperate woodlands are commonly dominated by ectomycorrhizal trees, whereas understory plants predominantly form arbuscular mycorrhizal associations. Due to differences in plant–fungus compatibility between canopy and ground layer vegetation the ‘mycorrhizal mediation hypothesis’ predicts that herbaceous plant establishment may be limited a lack of suitable fungal inoculum. We examined species data for 103 across Great Britain recorded 1971 2000 test whether richness was...
ABSTRACT Reptiles, squamates in particular, can be extremely valuable as indicator species due to their commonly small fundamental niche ranges. Yet these taxa are often overlooked North American Cenozoic palaeoecological studies favour of mammalian specimens. At the Coyote Canyon Mammoth Site (CCMS) on Columbia Plateau (eastern Washington State, USA) excavation has focused collection and subsequent identification all diagnostic fossil specimens, whether associated directly with mammoth...
Abstract Oaks ( Quercus spp.) are currently declining worldwide due to a multitude of threats. Woodland management is often heavily focused on thinning and burning nontarget species reduce competition promote oak dominance in the overstory. These techniques have typically been developed temperate regions, such as eastern U.S. forests, but whether they most effective strategy for promoting regeneration semiarid woodlands has not sufficiently examined. We conducted our study Edwards Plateau...
Forests are important for biodiversity, timber production and carbon accumulation, but these ecosystem services may be impacted by climate change. Field data collected from individual forest types occurring across a climatic gradient can contribute to forecasting consequences. We examined how changes in temperature, precipitation aridity affect 23 mature Douglas-fir ( Pseudotsuga menziesii ) forests nine regions 900 km British Columbia, Canada. Using Canadian National Forest Inventory...
