“…Co-occurring oaks may facilitate (or benefit) each other more than has been recognized (Callaway et al, 2002). Shade and fine-root dynamics of incumbent oaks may facilitate colonization of other oak species by preventing grasses from establishing (Callaway et al, 1991;Callaway & Davis, 1998) or by enhancing soil conditions (Chavez-Vergara et al, 2015). For example, oak species with low nutrient resorption in leaves may improve soil fertility, benefitting oaks with high nutrient resorption.…”

Yet examination of these linkages remains challenging due to the contrasting nature of focal systems and research approaches. Model clades provide a critical means to integrate ecology and evolution, as illustrated by the oaks (genus Quercus), an important model clade, given their ecological dominance, remarkable diversity, and growing phylogenetic, genomic, and ecological data resources. Studies of the clade reveal that their history of sympatric parallel adaptive radiation continues to influence community assembly today, highlighting questions on the nature and extent of coexistence mechanisms. Flexible phenology and hydraulic traits, despite evolutionary stasis, may have enabled adaptation to a wide range of environments within and across species, contributing to their high abundance and diversity. The oaks offer fundamental insights at the intersection of ecology and evolution on the role of diversification in community assembly processes, on the importance of flexibility in key functional traits in adapting to new environments, on factors contributing to persistence of long‐lived organisms, and on evolutionary legacies that influence ecosystem function.

“…It has been shown that when more than two species inhabit the same area, the community of microorganisms increments its abundance and activity promoting higher soil nutrient availability (Gartner and Cardon, 2004). Therein, a recent study found that Quercus deserticola benefits Q. castanea by incorporating nutrients to the soil and facilitating the decomposition of litter (Chávez-Vergara and García-Oliva 2013; Chávez-Vergara et al 2014;2015). Overall, this complementarity effects might promote coexistence.…”

“…Recently, it was detected that the association of two oak species produce higher nutrient availability, which resulted advantageous for one of the species (Chávez-Vergara et al 2014;2015). Although, this exhibited the benefits of species coexistence, the evidence supporting the frequency of the associations between oak species is still scant.…”

“…Particularly, nutrient availability and fire regime, topography, soil and altitude frequency have influenced oak distribution (Abrams, 1990;2003;Cavender-Bares et al 2004;Meave et al 2006;Olvera-Vargas et al 2010;Rodríguez-Trejo and Myers 2010;de la Riva et al 2014). However, it is still unknown if these patterns of oak distribution hold at regional scales.On the other side within communities, it is thought that species coexistence is promoted if they have a contrasting resource use strategy, are temporally separated at some point of their life stage, (Nakashizuka, 2001;Silvertown, 2004;Cavender-Bares and Pahlich 2009) or develop positive synergic effects between each other (Kaye et al 2000;Gartner and Cardon 2004;Chávez-Vergara et al 2014;2015).

Elucidating the factors determining plant distribution is still on discussion. It has been stated that the distribution is mostly determined by environmental factors, but the evidence on whether this or other processes are the determinants remains inconclusive. In the present study, we hypothesized that oak species differ in their distribution, which might be mostly influence by the environment. Particularly, we explored: i) the patterns of distribution of Quercus species at a landscape scale; ii) the climatic, soil and topographic factors that might determine their distribution, and iii) the degree of association between the species within fragments. The study included the analysis of 78 oak forest fragments at the Cuitzeo lake Basin in Michoacán state, Mexico in which nine oak species were registered. The species showed clear differences in their distribution; three groups of oak species that differ significantly in their spatial arrangement were detected with a NMDS (Non-metric Multidimensional Scaling) analysis. We observed a relationship between oak species distribution with temperature and precipitation. In particular, Q. candicans, Q. crassipes and Q. rugosa were frequently distributed at sites with higher rainfall and lower temperature; in contrast, Q. deserticola, Q. gentryi and Q. glaucoides were at more arid areas. We found associations between pairs of oak species; the most recurrent one was between species from the Quercus and the Lobatae sections. Overall, the pattern of distribution among oak species was determined by environmental factors, which suggests that they partition their habitat to avoid competition for resources. Key words: coexistence, ecological niche, habitat fragmentation, patterns of distribution, oaks.

Leaf senescence have shed light on its contribution to the recovery of nutrients and signaling of the transition from the active to the dormant stage in winter. The manner by which climatic and edaphic factors and plant phylogeny affect the senescent leaf economics spectrum (more mineral elements included) of different growth habits along elevational gradients in mountain ecosystems is highly uncertain. To fill this knowledge gap, we examined 15 representative subalpine forest species' senescent leaf functional traits (i.e., specific leaf area [SLA], leaf dry matter content [DMC], pH, carbon [C], nitrogen [N], phosphorus [P], potassium [K], calcium [Ca], sodium [Na], magnesium [Mg], manganese [Mn], aluminum [Al], iron [Fe], C:N, N:P, and C:P ratios) to determine the senescent leaf economics spectrum along elevational gradients in the Hengduan Mountains, China. Our results demonstrate that all the functional traits of senescent leaf showed strong correlations with one another, and K was observed as the hub for the leaf economics spectrum. Irrespective of the difference among growth habits (arbor vs. shrub), leaf habits (deciduous vs. evergreen), and leaf types (broad vs. needle), the variations in the two‐dimensional spectrum of the senescent leaf trait exhibited uniformly positive associations with elevation, primarily attributed to climatic drivers. However, the modulation of the senescent leaf economics spectrum by soil properties and plant phylogeny was surprisingly modest. Collectively, our results revealed that the resource trade‐off of senescent leaf showed a trend from acquisition to conservation along elevational gradients, which could broaden the plant economics spectrum to include senescent leaf.
