“…Further work by Paige documented overcompensation for ungulate herbivory in 10 additional scarlet gilia populations (Paige 1999) and found that scarlet gilia overcompensates even when rebrowsed (Paige 1992a, see also Paige 1992b). Subsequent studies demonstrated that other plant species can overcompensate for damage by various vertebrate herbivores, such as cattle (Loeser et al 2004), sheep (Liu et al 2012), horses (Lennartsson et al 1997), blackbirds (Dyer 1975), swans (Nolet 2004), geese (Van der Graaf et al 2005), and voles (Yeh et al 2012).…”

Not all herbivory is detrimental to plants. In some cases, plants can compensate for herbivory, maintain growth and fitness following damage, or even overcompensate for herbivory and perform better than if left undamaged. Examples of overcompensation to vertebrate herbivory are well known, but here we review the literature for examples of reproductive overcompensation (i.e., increased production of traits associated with fitness) and increased vegetative growth (i.e., vegetative overcompensation) following insect herbivory. We used a meta‐analysis to explore the effects of plant growth form, evolutionary history, herbivore feeding guild, and other plant and insect traits on the expression of reproductive and vegetative overcompensation by plants. Our literature search revealed 86 studies documenting examples of overcompensation for insect herbivory by 67 plant species representing 26 families. These plants included monocots and dicots, annuals and perennials, and woody and herbaceous plants. We also found that varied insect herbivores induce overcompensation, including 75 insect species in six orders representing 27 families and myriad feeding guilds. In our meta‐analysis, we calculated 53 effect sizes from 21 publications documenting reproductive overcompensation and 89 effect sizes from 40 publications documenting vegetative overcompensation. Variation in reproductive overcompensation was seen among plant growth forms, functional groups, cultivation, herbivore feeding sites, and plant and herbivore families. Variation in vegetative overcompensation was seen among plant families, herbivore families, and latitudinal gradients. We suggest overcompensation for insect herbivory may be far more prevalent than previously thought. Additional research focusing on the mechanisms, patterns, and ecological and evolutionary consequences of overcompensation for insect herbivory is likely to provide exciting new insights into this poorly understood and largely overlooked outcome of plant–insect interactions.

“…However, A. semotus and N. culturatus are known omnivores feeding on various plants and animals (Gan, 1995; Shaner et al, 2013; Yeh, 2012), whereas E. melanogaster and A. kikuchii are herbivorous (Bao & Zhuge, 1986; Gan, 1995; Liu et al, 1993; Yeh, 2012; Yeh et al, 2012). Alexandromys kikuchii in particular have a narrow diet favouring Yushan cane Yushania niitakayamensis (Yeh et al, 2012), which is in contrast to the broad diet of E. melanogaster comprising several dozens of plant species (Bao & Zhuge, 1986; Gan, 1995; Liu et al, 1993). At regional scale, A. kikuchii occurs in higher altitude, whereas E. melanogaster in lower altitude leading to their predominantly allopatric distribution (Yu, 1994).…”

Niche overlap in rodents increases with competition but not ecological opportunity: A role of inter‐individual difference

Niche variation at population level mediates niche packing (i.e. patterns of species' spread within the niche space) and species coexistence at community level. Competition and ecological opportunity (resource diversity) are two of the main mechanisms underlying niche variation. Dense niche packing could occur through increased niche partitioning or increased niche overlap. In this study, we used stable carbon and nitrogen isotope data of 635 individual rodents from four species across nine sites in the montane region of a subtropical island to test the effects of competition and ecological opportunity on population isotope niche size, inter‐individual niche difference within population and interspecific niche overlap within community. We used the Bayesian Standard Ellipse Area (SEAB, the ellipse area enclosed by carbon and nitrogen isotope values of organisms on a bi‐plot) to estimate population niche size and interspecific niche overlap. Inter‐individual niche difference within population was quantified as isotopic divergence and isotopic uniqueness. We used rodent abundance (the number of unique individuals captured) to measure competition and plant isotope niche size (plant SEAB) to measure ecological opportunity. The rodents experienced competition as evidenced by a negative relationship between population change rate and conspecific abundance. Rodent population niche size increased with ecological opportunity but not competition. The inter‐individual niche difference (isotopic uniqueness) increased with competition (interspecific competition only) but not ecological opportunity. At community level, interspecific niche overlap (herbivore–omnivore pair only) increased with competition (the combined abundance of the pair) but not ecological opportunity. This study demonstrated that isotope niche variation of the rodents could be hierarchically influenced by ecological opportunity and competition, with the former setting the limit of population niche size across communities and the latter shaping inter‐individual niche difference and interspecific niche overlap within communities. Under strong intraspecific competition and limited ecological opportunity for niche expansion, individuals may choose to increase their isotopic uniqueness from conspecifics at the cost of overlapping with heterospecifics of different trophic roles within the community niche space as overall competition increases. Denser niche packing of these rodent communities might be achieved through increased niche overlap.
