“…To some degree, leaf defences may be the product of gene × environment interactions, which could complicate the interpretation of measurements of traits in a common garden. However, predictors of herbivory to oaks planted at sites across North America were similar among sites (Pearse & Hipp ), suggesting consistency of oak phenotypes across environments.…”

Leaf habit does not determine the investment in both physical and chemical defences and pair‐wise correlations between these defensive traits

Plant life-history strategies associated with resource acquisition and economics (e.g. leaf habit) are thought to be fundamental determinants of the traits and mechanisms that drive herbivore pressure, resource allocation to plant defensive traits, and the simultaneous expression (positive correlations) or trade-offs (negative correlations) between these defensive traits. In particular, it is expected that evergreen species - which usually grow slower and support constant herbivore pressure in comparison with deciduous species - will exhibit higher levels of both physical and chemical defences and a higher predisposition to the simultaneous expression of physical and chemical defensive traits. Here, by using a dataset which included 56 oak species (Quercus genus), we investigated whether leaf habit of plant species governs the investment in both physical and chemical defences and pair-wise correlations between these defensive traits. Our results showed that leaf habit does not determine the production of most leaf physical and chemical defences. Although evergreen oak species had higher levels of leaf toughness and specific leaf mass (physical defences) than deciduous oak species, both traits are essentially prerequisites for evergreenness. Similarly, our results also showed that leaf habit does not determine pair-wise correlations between defensive traits because most physical and chemical defensive traits were simultaneously expressed in both evergreen and deciduous oak species. Our findings indicate that leaf habit does not substantially contribute to oak species differences in plant defence investment.

; Padilla-Díaz, Carmen M.; Pearse, Ian S.; Pérez-Ramos, Ignacio M.; Vázquez-Piqué, Javier; and Pesendorfer, Mario B., "Is the relationship between mast-seeding and weather in oaks related to their life-history or phylogeny?" (2016 Abstract. Although the functional basis of variable and synchronous seed production (masting behavior) has been extensively investigated, only recently has attention been focused on the proximate mechanisms driving this phenomenon. We analyzed the relationship between weather and acorn production in 15 species of oaks (genus Quercus) from three geographic regions on two continents, with the goals of determining the extent to which similar sets of weather factors affect masting behavior across species and to explore the ecological basis for the similarities detected. Lag-1 temporal autocorrelations were predominantly negative, supporting the hypothesis that stored resources play a role in masting behavior across this genus, and we were able to determine environmental variables correlating with acorn production in all but one of the species. Standard weather variables outperformed "differential-cue" variables based on the difference between successive years in a majority of species, which is consistent with the hypothesis that weather is linked directly to the proximate mechanism driving seed production and that masting in these species is likely to be sensitive to climate change. Based on the correlations between weather variables and acorn production, cluster analysis failed to generate any obvious groups of species corresponding to phylogeny or life-history. Discriminant function analyses, however, were able to identify the phylogenetic section to which the species belonged and, controlling for phylogeny, the length of time species required to mature acorns, whether they were evergreen or deciduous, and, to a lesser extent, the geographic region to which they are endemic. These results indicate that similar proximate mechanisms are driving acorn production in these species of oaks, that the environmental factors driving seed production in oaks are to some extent phylogenetically conserved, and that the shared mechanisms driving acorn production result in some degree of synchrony among coexisting species in a way that potentially enhances predator satiation, at least when they have acorns requiring the same length of time to mature.

Invasive plants disrupt both floral and faunal communities of the invaded regions. Influence of invasive plants on ecosystem functioning and dynamics in the invaded region can be understood by taking into consideration complex interactions between native insects and non-native plants. This review attempts to synthesize available key literature on the effects of plant invasion on native insect communities and the role of native insects in control or spread of invasive plants. The toxic or attractive nature of invasive plants will have bearing on the novel associations that native insects form with the invasive plants and consequently in regulating their population. This study examines the consequences of herbivory and pollination on invasive plants upon encounters with native insects in the invaded regions and illustrates a sequence of possible changes that native insects and invasive plants interactions may bring about within a biotic community.
