“…Pin cherry's response, however, is consistent with the reported lack of NO 3 -reductase in its leaves (Truax et al 1994). Patterns in species mineral N-form responses to the nutrient affinity index are generally consistent with the availability of N forms in the soil fertility gradients over which our species are distributed in the upper Great Lakes region (Zak et al 1989;Walters and Reich 1997;Baribault et al 2010;Walters and Gerlach 2013). Of the species that responded to , American elm and white ash are restricted to the most fertile glacial moraine soils.…”

“…Temporal variation in N is often associated with disturbance (an ephemeral increase in NO 3 − -N availability; Jerabkova et al 2011). Spatial variation in N at landscape scales is high among postglacial landforms (Zak et al 1989;Walters and Reich 1997;Baribault et al 2010) and also at much finer scales (1 m; Garten et al (2007)). Given that temperate forest tree species are reported to vary in their growth responses to both N (Kobe 2007) and N forms (Marschner 2008), large spatiotemporal variation in N may help determine species distributions over both landscape-scale fertility gradients and within local forest communities (e.g., Frelich et al 2003).…”

Tree species distributions and diversity could be explained by rank changes in performance over multiple spatiotemporal resource gradients, i.e., resource partitioning. For 14 species planted in 45 harvest gap and closed canopy locations in a mesic northern hardwood forest community, Michigan, USA, we asked the following questions: (i) are species growth responses to light, nitrogen (N), or N form (ammonium vs. nitrate) related to their ecological distributions and phylogenies? and (ii) is there evidence of growth-based resource partitioning over measured resource gradients? Growth responses to the N form were consistent with both differences in uptake energy requirements between N forms and their availability through succession and across fertility gradients; height growth was negatively related to the species shade-tolerance score, especially in high light, i.e., shade-intolerant species responded to soil nitrate-N and shade-tolerant species responded to ammonium-N; fertile soil associated species responded to nitrate-N and infertile soil associated species to ammonium-N; and gymnosperms responded to ammonium-N and angiosperm responses varied. Modeled growth responses to resources showed only modest evidence for rank changes over resource gradients, with N contributing less to rank changes than light. Thus, growth responses to resources were accurately predicted by species ecology and (or) phylogeny; however, there was only modest support for the notion that growth-based resource partitioning underlies community-scale diversity in a northern hardwood forest.Résumé : La distribution et la diversité des espèces d'arbre pourraient être expliquées par des changements de classe de performance selon de multiples gradients spatiotemporels de ressources, c'est-à -dire la répartition des ressources. Pour 14 espèces plantées à 45 endroits (trouée forestière ou couvert fermé) dans une communauté de feuillus nordiques établie sur une station mésique du Michigan, aux États-Unis, nous avons posé les questions suivantes : (i) est-ce que la réaction de croissance des espèces à la lumière, à l'azote (N) ou à la forme de N (ammonium ou nitrate) est reliée à leur distribution écologique et à leur phylogénie? et (ii) est-ce qu'il y a des signes de répartition des ressources fondée sur la croissance selon le gradient des ressources mesurées? La croissance en hauteur était négativement reliée au degré de tolérance à l'ombre des espèces, particulièrement en conditions de forte luminosité. En fonction des gradients de succession et de fertilité, la réaction de croissance à N était généralement cohérente avec la disponibilité des formes de N et des exigences énergétiques pour leur absorption : les espèces intolérantes à l'ombre réagissaient à N du sol sous forme de nitrate et les espèces tolérantes à l'ombre à N sous forme d'ammonium; les espèces associées aux stations fertiles réagissaient à N sous forme de nitrate et les espèces associées aux sols infertiles à N sous forme d'ammonium; les gymnospermes réagissaient à N sous forme d'am...

Soil-vegetation relationships in a toposequence of the Guayana Shield, Venezuela. The Guayana Shield is one of the oldest territories in the planet and has millions of years subjected to leaching and erosion processes that produce oligotrophic soils. This scarcity of nutrients has not avoided the development of high, diverse and magnificent forests, where plants have adaptations to survive these difficult conditions. The aim of this work was to characterize the physical and chemical parameters of the soils in different forest communities of the imataca Forest Reserve (iFR), to establish some interpretations on their origin, and some relationships between the edaphic components and the inhabitant species. Terrestrial journeys were carried out and two pathways were traced for the interpretation of forest communities. in each community, three plots (100m x 100m) for the ecological survey were established. In each plot, all trees, palms, and lianas were measured (dbh≥10cm; dbh: diameter at breast height); four 10m x 10m understory sub-plots were evaluated, and a census of all the spermatophyta species (dbh<10cm) was made. Soils were evaluated by means of a trial pit in each community, and a bore in each one understory sub-plot. The obtained data were analyzed by both a detrended and a canonical correspondence analysis. Results from a total of 15 plots allowed us to identify three communities: a forest dominated by Mora excelsa located in a narrow valley with high content of silt; a swamp forest dominated by Catostemma commune in a sandy broad valley, and a forest in clay hills dominated by Alexa imperatricis. Most of the soils had a pH between 3.1 and 4.5. Nutrients were in very low concentrations (N: 0-0.2%; P: 0-14ppm; K: 0-0.3Cmol/kg) and Al in toxicity quantities. We observed that Ca/Al relationship greater than 1 meant a neutralization of the toxic effect of Al. Besides, basal area ranged from 20.4 to 32.3m 2 /ha; the highest level (top local forest development) corresponded with the C. commune community with a Ca/Al value of 2.5. This research found an adequate relationship between soil and vegetation, as it was able to identify three communities into three distinct soil conditions. Nevertheless, edaphic constraints indicated that high forest cover must be maintained as an essential element for the conservation of these communities. Rev. Biol. Trop. 62 (1): 385-401. Epub 2014 March 01.Key words: oligotrophic soils, soil toxicity, imataca, tropical forests, ecosystem susceptibility.Desde hace poco más de un siglo, el trabajo de Flahault & Schöter (citados por Biondi, 2011) reconoce que una asociación es una agrupación vegetal con una determinada composición florística, que presenta una fisionomía uniforme y que se desarrolla en condiciones invariables del sitio. Esta es la base de Teoría Organísmica (Clements, 1916) y de la rama ecológica denominada Fitosociología (Braun-Blanquet, 1979), donde se considera que las comunidades vegetales pueden ser identificadas y clasificadas en un sistema jerár-quico....

“…Widespread calcium depletion has been implicated as a factor contributing to decline of sugar maple and red spruce in certain areas (DeHayes et al, 1999;Horsley et al, 2002). Baribault et al (2010) argued that net primary productivity of northern forests is constrained by a function of available water, nitrogen, and calcium. Regardless of the degree to which calcium limits productivity of trees, the foliar response to liming changes the quality of the substrate for litter decay in limed forests, and our results indicate that this may be true, in varying degrees, for a variety of tree species.…”
