“…These intimate fungus-plant mutualisms play crucial ecological roles by determining the nutrient acquisition and drought tolerance of trees (Smith and Read 2008). There is concern that we lack baseline data on mycorrhizal species distributions and abundances against which to assess the effects of global change (Courty et al 2010;Kjøller et al 2012;Lilleskov and Parrent 2007;Peay et al 2010). Research on mycorrhizas has been focused at local scales (i.e.…”

“…Ectomycorrhizal communities are usually composed of a diverse flora consisting of several dominant and many infrequent EMF species (Buée et al, 2007;Courty et al, 2010;Pena et al, 2010;Tedersoo et al, 2012a;Danielsen et al, 2013). EMF community structures are strongly influenced by N deposition (Lilleskov et al, 2011;Kjøller et al, 2012). Stable isotope studies have revealed that EMF species differ in their abilities to exploit different N sources (Hobbie and Hö gberg, 2012).…”

Mycorrhizal fungi have a key role in nitrogen (N) cycling, particularly in boreal and temperate ecosystems. However, the significance of ectomycorrhizal fungal (EMF) diversity for this important ecosystem function is unknown. Here, EMF taxon-specific N uptake was analyzed via 15 N isotope enrichment in complex root-associated assemblages and non-mycorrhizal root tips in controlled experiments. Specific 15 N enrichment in ectomycorrhizas, which represents the N influx and export, as well as the exchange of 15 N with the N pool of the root tip, was dependent on the fungal identity. Light or water deprivation revealed interspecific response diversity for N uptake. Partial taxonspecific N fluxes for ectomycorrhizas were assessed, and the benefits of EMF assemblages for plant N nutrition were estimated. We demonstrated that ectomycorrhizal assemblages provide advantages for inorganic N uptake compared with non-mycorrhizal roots under environmental constraints but not for unstressed plants. These benefits were realized via stress activation of distinct EMF taxa, which suggests significant functional diversity within EMF assemblages. We developed and validated a model that predicts net N flux into the plant based on taxon-specific 15 N enrichment in ectomycorrhizal root tips. These results open a new avenue to characterize the functional traits of EMF taxa in complex communities.

“…Overall, land use intensification such as tillage, mowing, use of tracked mowers and increased nitrogen deposition had negative impact on functional diversity of different organisms (Pelosi et al, 2014;Lilleskov et al, 2011;Krause and Culmsee, 2013). While there is a relative consensus that reducing the land use intensification may contribute to maintain functional diversity, land abandonment also seems to have negative impacts (Fontana et al, 2014).…”

Functional diversity is increasingly pointed as a useful approach to reach Biological Conservation goals. Here, we provide an overview of the functional diversity approach status in the Biological Conservation field. We sought for peer-reviewed papers published over a period of twenty years (from 1994 to 2014). First we used the general topic "functional diversity" and then refined our search using the key-word "conservation". We have identified the conservation strategies addressed, the organism studied, and the continent of study site in each paper. Thirteen classes of conservation strategies were identified. Plants were the most commonly studied organism group and most study-sites were located in Europe. The functional diversity approach was introduced in the Biological Conservation field in the early 2000's and its inclusion in conservation strategies is broadly advised. However, the number of papers that operationalise such inclusion by developing models and systems is still low. Functional diversity responds differently and eventually better than other measures to changes in land use and management, which suggests that this approach can potentially better predict the impacts. More studies are needed to corroborate this hypothesis. We pointed out knowledge gaps regarding identification of the responses for functional diversity about urban impacts and in research on the level of management intensity of land needed to maintain functional diversity. We recommend the use of functional diversity measures to find ecological indicators. Future studies should focus on the development of functional diversity measures of other taxa beyond plants as well as test hypothesis in tropical ecosystems.Keywords: biodiversity assessments, biodiversity measures, conservation strategies, ecosystem functioning, trait-based approach. Uma visão geral sobre a aplicabilidade da diversidade funcional na Conservação Biológica ResumoA diversidade funcional é crescentemente apontada como uma abordagem útil para alcançar os objetivos da Conservação Biológica. Neste artigo, nós mostramos uma visão geral do status desta abordagem no campo da Conservação Biológica. Nós buscamos por artigos revisados por pares publicados ao longo de vinte anos (desde 1994 até 2014) usando, primeiramente, o tópico geral "functional diversity" e em seguida, refinamos a pesquisa com a palavra-chave "conservation". Identificamos a estratégia de conservação abordada, o organismo estudado e o continente da área de estudo de cada artigo. Treze classes de estratégias de conservação foram identificadas. As plantas foram o grupo de organismos mais amplamente estudado e a maior parte das áreas de estudo estavam localizadas no continente europeu. A abordagem da diversidade funcional entrou no campo da Conservação Biológica no início dos anos 2000 e sua inclusão nas estratégias de conservação é amplamente recomendada. Entretanto, o número de artigos que operacionalizam tal inclusão ainda é pequeno. A diversidade funcional responde diferentemente e, eventualmente,...
