“…In several forest types, edge formations appear to act positively on herbivore activity; Wirth et al (2008) verified that approximately 80 % of such studies indicated this tendency. This result may be related to a preference by adult insects to oviposite on plants that are more exposed to the sun (Moore et al 1988), and thus a faster development of insects near the edge (Cappuccino & Martin 1997). It also may be due to the physiological conditions of the plants, such as higher nutritional value of the leaves due to the disponibility of nitrogen and soluble sugars, thus increasing the quality of the food and its palatability (Fortin & Maufette 2001).…”

Biotic and abiotic factors, such as luminosity, temperature, air humidity, and herbivory, can affect the establishment of reintroduced plants in natural habitats. This study evaluated the effects of these factors on the survival and growth of Cattleya intermedia plants reintroduced into a forest fragment in South Brazil. Plants of C. intermedia were obtained from in vitro seed germination in asymbiotic culture. Eighty-eight plants were reintroduced at both the forest edge and forest interior. Plants with greater shoot heights and number of leaves and pseudobulbs suffered more damage from herbivores at the edge. There were no significant differences in morphometric parameters between damaged and non-damaged plants in the interior. Tenthecoris bicolor, Helionothrips errans, Ithomiola nepos, Molomea magna and Coleoptera larvae damaged C. intermedia. Luminosity was higher at the edge, while air humidity and temperature were the same in both environments. Herbivory associated with abiotic factors increased plant mortality in the interior, while abiotic factors were determinative of plant survival at the edge. Luminosity is important to the survival of reintroduced epiphytic orchids, and herbivory affects the success of reintroduction.

“…With respect to the current study system, the role of positive edge effects seems a likely explanation for the observed findings. Positive responses to edges have been commonly observed in many different systems, for example forests (Cappuccino & Martin 1997, Didham et al 1998, seagrass meadows (Irlandi et al 1995, Warry et al 2009) and freshwater lakes (Trebitz & Nibbelink 1996).…”

Modification of the abiotic environment and creation of habitat by ecosystem engineers is an important ecological process. According to landscape ecology, the configuration (distance apart and spatial arrangement) of patches of engineered habitat within landscapes can also influence the physical environment and biodiversity. To examine the influence of a model engineer, the marine intertidal mussel Trichomya hirsuta, abiotic variables (sand deposition, temperature, and humidity) and biotic variables (species richness, numbers of unique species, densities of generalist species and entire assemblages) were compared between engineered and unmodified habitat and between different configurations of engineered patches. By keeping the number of habitat patches (i.e. mussels) constant, the effect of patch configuration (in terms of degree of patch aggregation) on the same abiotic and biotic variables was investigated. Mussels were found to trap large amounts of sand and engineer intertidal habitat that was cooler and, to a lesser extent, more humid during low tides. Mussels also had more species, more unique species and different assemblages compared to habitat without mussels. Different configurations of mussels had similar effects on the physical environment and had similar assemblages as a whole. Most importantly, regularly spaced solitary mussels had more edge and consequently more species, unique species and densities of generalists. These key findings suggest that the configuration of patches of habitat is a crucial factor affecting mussel bed biodiversity, and fragmentation of habitat into regularly spaced patches may have a positive influence on biodiversity due to the positive response of other species to habitat edges.

“…We found that the abundance of herbivorous insects, such as Lepidoptera and Orthoptera, increased with increasing gap size. This is probably because lepidopteran larvae prefer the edges of canopy gaps (Cappuccino & Martin, 1997;Cappuccino & Root, 1992;Courtney & Courtney, 1982), and they migrate from the canopy to the understory as canopy leaf quality degrades (leaf toughness and tannin increased, while the nitrogen and water contents decreased) in late season (Murakami & Wada, 1997). These lepidopteran larvae feed canopy trees and understory plants (Murakami & Wada, 1997), thus, most of these Lepidoptera larvae may be generalists.…”

1.Availabilities of light and soil nitrogen for understory plants vary by extent of canopy gap formation through typhoon disturbance. We predicted that variation in resource availability and herbivore abundance in canopy gaps would affect herbivory through variation in leaf traits among plant species. We studied six understory species that expand their leaves before or after canopy closure in deciduous forests. We measured the availabilities of light, soil nitrogen, soil water content, and herbivore abundance in 20 canopy gaps (28.3-607.6 m 2 ) formed by a typhoon and in four undisturbed stands.We also measured leaf traits and herbivory on understory plants. 2.The availabilities of light and soil nitrogen increased with increasing gap size.However, soil water content did not. The abundance of herbivorous insects (such as Lepidoptera and Orthoptera) increased with increasing gap size. 3.Concentrations of condensed tannins, total phenolics, and nitrogen in leaves and the leaf mass per area increased in late leaf expansion species with increasing gap size, while none of the leaf traits varied by gap size in early leaf expansion species. 4.Herbivory increased on early leaf expansion species with increasing gap size, but decreased on late leaf expansion species. In these late leaf expansion species, total phenolics and C:N ratio had negative relationships with herbivory.Takafumi et al. 3 5.These results suggested that following typhoon disturbance, increased herbivory on early leaf expansion species can be explained by increased herbivore abundance, while decreased herbivory on late leaf expansion species can be explained by variation in leaf traits.
