“…The highest values of Jaccard and Sorensen indices are presented between the selective cutting and seed tree cutting in 1998. As the forest develops, a larger number of species is seen due to the stand opening and to the both, biotic and abiotic conditions that are modified when silvicultural practices are applied (Alanís-Rodríguez et al, 2010;Ares et al, 2009;Berger & Puettmann, 2000).…”

“…Los valores mayores de los índices de Jaccard y Sorensen se presentan entre la corta de selección y la de árboles padre realizadas en 1998. A medida que la masa forestal se desarrolla, se comparte un número mayor de especies debido a la apertura de claros y a las condiciones bióticas y abióticas que se modifican al realizar las prácticas silvícolas (Alanís-Rodríguez et al, 2010;Ares et al, 2009;Berger & Puettmann, 2000).…”

“…Understory is a key component of forest ecosystems because it provides habitat for wildlife and contributes to nutrient cycling, resulting in the maintenance of productive capacity in managed forests (Ampooter, Beaten, Koricheva, Vanhellemont, & Verheyen, 2014;Berger & Puettmann, 2000;Davis & Puettmann, 2009). This study considers that the understory (shrubs and herbs) is an integral component of the structure of managed forest.…”

“…El sotobosque es un componente clave de los ecosistemas forestales, ya que provee hábitat para la fauna silvestre y contribuye en el ciclo de nutrientes, lo que se traduce en el mantenimiento de la capacidad productiva en bosques bajo manejo (Ampooter, Beaten, Koricheva, Vanhellemont, & Verheyen, 2014;Berger & Puettmann, 2000;Davis & Puettmann, 2009). En el presente estudio se considera que el sotobosque Therefore, the objectives of this study were 1) to obtain richness, species composition and diversity indices (alpha and beta) of the tree layer and understory in forests managed under different silvicultural treatments and application times and 2) determine whether there are differences in the variables analyzed in a managed forest (silviculture and application time), when compared with unmanaged forest.…”

I n the present study, the effect of silvicultural practices on richness, composition and diversity of tree species, herbaceous and shrub species in a forest community of Santa Catarina Ixtepeji, Oaxaca was evaluated. To this end, the following silvicultural treatments were evaluated: selective cutting (1998), light thinning (2011) and seed tree cutting (1998 and 2011). Alpha and beta diversity indices of tree communities (shrub and herbaceous) were estimated, and also the Importance Value index (IVI) of the tree layer. The results showed that the herbaceous component is the most diverse in both stands with and without silvicultural management, followed by the shrub component. According to the IVI, Pinus oaxacana Mirov was the most important ecological species in all treatments evaluated, including unmanaged forest. The results indicate that logging modifies richness, diversity and composition of the tree strata (shrub and herbaceous), these two tree strata are the largest contributors to diversity. Therefore it is important to assess the understory, because it helps giving a better explanation of the total plant diversity of the forest. ResumenE n el presente estudio se investigó el efecto de las prácticas silvícolas sobre la riqueza, composición y diversidad de las especies arbóreas, herbáceas y arbustivas en un bosque de la comunidad de Santa Catarina Ixtepeji, Oaxaca. Para tal fin, los siguientes tratamientos silvícolas fueron evaluados: corta de selección 1998, aclareo ligero 2011 y árboles padre 1998 y 2011. Los índices de diversidad alfa y beta de las comunidades arbórea, arbustiva y herbácea se estimaron, así como el índice de valor de importancia (IVI) del estrato arbóreo. Los resultados mostraron que el componente herbáceo es el más diverso tanto en rodales bajo manejo silvícola como sin manejo, seguido del componente arbustivo. De acuerdo con el IVI, la especie de mayor importancia ecológica fue Pinus oaxacana Mirov. en todos los tratamientos evaluados, incluyendo el bosque sin manejo. Los resultados indican que el aprovechamiento forestal modifica la riqueza, diversidad y composición de los estratos arbóreo, arbustivo y herbáceo, siendo los dos últimos estratos los que más contribuyen a la diversidad. Por lo anterior resulta importante evaluar el sotobosque, ya que ayuda a dar una mejor explicación de la diversidad vegetal total del bosque. Palabras clave: Tratamiento silvícola, vegetación del sotobosque, estructura del rodal, índices de biodiversidad.

“…Total understory biomass, individual species biomass, and species composition of the understory vegetation are known to be affected by the amount of light reaching the forest floor, which is driven by overstory species composition, as well as stand and crown structure (Alaback, 1982;Berger and Puettmann, 2000;Hunt et al, 2005;Legare et al, 2002;Peek et al, 2001). Understory species composition and biomass are also affected by leaf litter (Harrington et al, 2003), productivity (Adkison and Gleeson, 2004), soil nutrient concentrations (Hunt et al, 2005), nitrogen deposition rate (Rainey et al, 1999), throughfall precipitation (Anderson et al, 1969), above and below ground competition with overstory vegetation (Harrington et al, 2003;Riegel et al, 1992), disturbance (Moser et al, 1996), and successional dynamics (Gleeson and Tilman, 1990).…”

Overstory Community Composition and Elevated Atmospheric CO2 and O3 Modify Understory Biomass Production and Nitrogen Acquisition

et al. 2006

Elevated atmospheric CO 2 and O 3 have the potential to affect the primary productivity of the forest overstory, but little attention has been given to potential responses of understory vegetation. Our objective was to document the effects of elevated atmospheric CO 2 and O 3 on understory species composition and biomass and to quantify nitrogen (N) acquisition by the understory vegetation. The research took place at the aspen free-air CO 2 and O 3 enrichment (FACE) experiment, which has four treatments (control, elevated CO 2 , elevated O 3 , and elevated CO 2 +O 3 ) and three tree communities: aspen, aspen/birch, and aspen/ maple. In June 2003, each FACE ring was uniformly labeled with 15N applied as NH 4 Cl. Understory biomass was harvested in June of 2004 for productivity, N, and 15N measurements, and photosynthetically active radiation (PAR) was measured below the canopy. The understory was divided into five species groups, which dominate in this young aggrading forest: Taraxacum officinale (dandelion), Solidago sp. (goldenrod), Trifolium repens and T. pretense (clover), various species from the Poaceae family (grass), and composited minor components (CMC). Understory species composition, total and individual species biomass, N content, and 15N recovery showed overstory community effects, but the direct effects of treatments was masked by the high variability of these data. Total understory biomass increased with increasing light, and thus was greatest under the open canopy of the aspen/maple community, as well as the more open canopy of the elevated O 3 treatments. Species were different from one another in terms of 15N recovery, with virtually no 15N recovered in clover and the greatest amount recovered in dandelion. Thus, understory species composition and biomass appear to be driven by the structure of the overstory community, which is determined by the tree species present and their response to the treatments. However, N acquisition by the understory does not appear to be affected by either the overstory community or the treatments at this point.

Changes in microclimate, soil physicochemical properties, understory vegetation cover, diversity, and composition as well as soil microbial community resulting from silvicultural practices are expected to alter soil food webs. Here, we investigated whether and how contrasting‐sized canopy openings affect soil nematode community within a 30 year‐aged spruce plantation. The results indicated that the responses of soil nematodes to canopy opening size were dependant on their feeding habit. The abundance of total nematodes and that of free‐living nematodes was negatively correlated with soil bulk density, whereas the abundance of omnivore–predators was negatively correlated with soil bulk density and shrubs cover, respectively. The ratio of the sum abundance of predators and omnivores to the plant parasites’ abundance, Simpson's dominance index, Pielou's evenness index, and sigma maturity index, maturity index (MI), MI 2‐5, basal index, enrichment index, and structure index was sensitive to alteration in canopy opening size. Multivariate analysis indicated that thinning‐induced gap size resulted in contrasting nematode assemblages. In conclusion, soil nematodes should be integrated as an indicator to monitor soil multifunctionality change due to thinning.
