The effect of tree species diversity on fine-root production in a young temperate forest
The phenomenon of overyielding in speciesdiverse plant communities is mainly attributed to complementary resource use. Vertical niche differentiation belowground might be one potential mechanism for such complementarity. However, most studies that have analysed the diversity/productivity relationshi...

Here we used a 5—6 year old forest diversity experiment to analyse how fine-root (<2 mm) production in ingrowth cores (0—30 cm) was influenced by tree species identity, as well as the species diversity and richness of tree neighbourhoods. Fineroot production during the first growing season after the installation of ingrowth cores increased slightly with tree species diversity, and four-species combinations produced on average 94.8% more fine-root biomass than monocultures. During the second growing season, fine-root mortality increased with tree species diversity, indicating an increased fine-root turnover in species-rich communities. The initial overyielding was attributable to the response to mixing by the dominant species, Pseudotsuga menziesii and Picea abies, which produced more fine roots in mixtures than could be expected from monocultures. In species-rich neighbourhoods, P. abies allocated more fine roots to the upper soil layer (0—15 cm), whereas P. menziesii produced more fine roots in the deeper layer (15—30 cm) than in species-poor neighbourhoods. Our results indicate that, although there may be no lasting overyielding in the fineroot production of species-diverse tree communities, increasing species diversity can lead to substantial changes in the production, vertical distribution, and turnover of fine roots of individual species.</description><identifier>ISSN: 0029-8549</identifier><identifier>EISSN: 1432-1939</identifier><identifier>DOI: 10.1007/s00442-012-2259-2</identifier><identifier>PMID: 22298110</identifier><language>eng</language><publisher>Berlin/Heidelberg: Springer</publisher><subject>Abies ; Biological diversity ; Biomass ; Biomass production ; Biomedical and Life Sciences ; Climate ; Complementarity ; Cores ; Differentiation ; Dominant species ; Ecology ; ECOSYSTEM ECOLOGY ; Ecosystem ecology - Original research ; Forest ecosystems ; Forest soils ; Forests ; Germany ; Growing season ; Growing seasons ; Hydrology/Water Resources ; Life Sciences ; Monoculture ; Mortality ; Niche (Ecology) ; Niches ; Picea - physiology ; Picea abies ; Plant communities ; Plant diversity ; Plant roots ; Plant Roots - growth & development ; Plant Roots - physiology ; Plant Sciences ; Plant species ; Plants ; Pseudotsuga - physiology ; Pseudotsuga menziesii ; Roots ; Soil ; Species ; Species diversity ; Species Specificity ; Temperate forests ; Trees ; Trees - physiology ; Vertical distribution ; Virgin soils</subject><ispartof>Oecologia, 2012-08, Vol.169 (4), p.1105-1115</ispartof><rights>Springer-Verlag Berlin Heidelberg 2012</rights><rights>Springer-Verlag 2012</rights><rights>COPYRIGHT 2012 Springer</rights><lds50>peer_reviewed</lds50><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-c594t-e43c4bae0507809a69db983a3b1fb620ad26bbdb5b9cb2569da8e750aec36caa3</citedby><cites>FETCH-LOGICAL-c594t-e43c4bae0507809a69db983a3b1fb620ad26bbdb5b9cb2569da8e750aec36caa3</cites></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><linktopdf>$$Uhttps://www.jstor.org/stable/pdf/23260142$$EPDF$$P50$$Gjstor$$H</linktopdf><linktohtml>$$Uhttps://www.jstor.org/stable/23260142$$EHTML$$P50$$Gjstor$$H</linktohtml><link.rule.ids>314,776,780,799,27901,27902,41464,42533,51294,57992,58225</link.rule.ids><backlink>$$Uhttps://www.ncbi.nlm.nih.gov/pubmed/22298110$$D View this record in MEDLINE/PubMed$$Hfree_for_read</backlink></links><search><creatorcontrib>Lei, Pifeng</creatorcontrib><creatorcontrib>Scherer-Lorenzen, Michael</creatorcontrib><creatorcontrib>Bauhus, Jürgen</creatorcontrib><title>The effect of tree species diversity on fine-root production in a young temperate forest</title><title>Oecologia</title><addtitle>Oecologia</addtitle><addtitle>Oecologia</addtitle><description>The phenomenon of overyielding in speciesdiverse plant communities is mainly attributed to complementary resource use.
