abstract = {Fluctuating asymmetry (FA), a widely used measure of developmental instability in plants and animals, which describes random differences in size and/or shape between the two sides of a bilateral character. We used FA as a tool to detect stress in three mangrove species (Avicennia germinans, Laguncularia racemosa, Rhizophora mangle), growing in both disturbed and conserved habitats in the Atlantic coast of Mexico. In this region, disturbed habitats are the result of deforestation, livestock, tourism and agriculture activities. Twenty plants of each species were sampled in each of four sites (two disturbed and two conserved) and levels of FA, proportion of individuals with herbivory, proportion of leaves with damage, and leaf area removed by herbivores were evaluated. In disturbed habitats, regardless of plant species, more plants were attacked by insects, more leaves were damaged, and more leaf area was removed by herbivores, indicating higher overall damage to plants. We detected that FA levels varied significantly amongst mangrove species, they were higher in disturbed compared to conserved habitats, indicating the importance of FA as a monitoring tool of mangrove stress. A positive relationship between FA and herbivory levels also indicates that herbivores might be a source of stress.},

abstract = {Interspecific hybridization is a prevalent process in plant species that may have different ecological and evolutionary consequences. Interactions with herbivorous insects may be altered because of hybridization among host plants. These changes result from the morphological, physiological and chemical traits expressed in hybrid individuals. Therefore, it is of interest to document the changes in traits such as leaf morphology and their consequences on patterns of herbivory by insects in hybrid complexes of plants. Another useful indicator that may serve to evaluate developmental instability resulting from genetic or environmental stress in hybrid plants is fluctuating asymmetry. In this study, we used two previously genetically characterized complexes of hybridizing Mexican oaks as models to compare and understand the relationships between leaf morphology, fluctuating asymmetry and herbivory levels in parental and hybrid individuals. Results indicated that in the Quercus affinis × Q. laurina complex, hybrid individuals show a distinct morphology in relation to the parental species, while in the Q. magnoliifolia × Q. resinosa complex, hybrids were similar to Q. resinosa. In both hybrid complexes, our results show that hybrid individuals have higher levels of fluctuating asymmetry and herbivory levels, which may reflect higher levels of genetic or environmental stress in comparison to the parental species. These results might help explain why oak species usually remain distinct despite the high frequency of hybridization characteristic of the genus.},

abstract = {Mistletoes are parasitic plants that show effects that can parallel or contrast with those caused by herbivores to their host plants, particularly on aspects such as host biomass, resource allocation patterns, and interspecific interactions at the community level. In this study, we evaluated the potential synergistic effects of herbivory and infection by the mistletoe Psittacanthus calyculatus on nutritional quality and chemical defense of the white oak Quercus deserticola along forest fragments in Mexico. For this, we sampled leaves of parasitized oaks, unparasitized oaks and mistletoes at four forest fragments in the Cuitzeo basin, Michoacán state, Mexico, and measured herbivory levels and foliar water content, total nonstructural carbohydrates, phenols, flavonoids, and hydrolyzable tannins in each sample. Higher levels of infection by P. calyculatus were found in the smaller forest fragments, while foliar damage by herbivores was higher in larger forest fragments. At all sites, levels of herbivory were lower in the mistletoe than in both parasitized and unparasitized oaks. However, there was a positive relationship between herbivory levels in parasitized oaks and their mistletoes. Also, foliar water content and total phenol concentration were positively correlated between the oaks and the mistletoes. The results suggest that herbivory levels in parasitized hosts and mistletoes depend on the close physiological interaction between the nutritional quality and the chemical defense of the two plants involved. This is one of the few studies analyzing the chemical ecology of the interaction between plant hosts and plant parasites.},

abstract = {The urbanization of the natural landscape has spread along the major axis of all large towns worldwide, what has resulted in an unprecedented increase in habitat fragmentation and ultimately in a mosaic of patches of native vegetation. These changes have a continuum of impacts on the processes and mechanisms that shape habitat diversity and species interactions. An important and overlooked aspect that may aid in the understanding of the effects of urbanization on species interactions is herbivory. Herbivores and leaf removal can signalize the effects of the habitat via their host plants. Another potentially useful measure for evaluating the effects of environmental stress on particular species is fluctuating asymmetry. We studied the herbivory levels and leaf fluctuating asymmetry on Solanum lycocarpum (Solanaceae) along an urban gradient in Brazil. The leaf area removed by folivores differed among sites and was significantly greater in the site with the higher level of urbanization. Also, the area removed varied significantly among individuals within urbanization sites. Similarly, the frequency of leaves with folivore damage was greater in the site with higher urbanization, although the area removed by them did not differ between shorter and larger plants. FA was significantly greater in the more urbanized sites in comparison with the other sites in the urbanization gradient and varied among individuals within site. Finally, we found a positive relationship between leaf area removed and FA values in the urbanization gradient. These results indicate that increased urbanization causes a reduction in habitat suitability for S. lycocarpum, which is reflected on higher FA levels. The leaf herbivores may benefit from the stress levels of hosts on more urbanized sites, which may have been caused by several factors acting in combination such as lower defenses, higher susceptibility and natural enemy pressures via habitat fragmentation/urbanization. This study exemplifies the variety of effects that urbanization exerts on remnant native populations and that fluctuating asymmetry could be a useful measure of the effects of these challenges on plant populations, and might also be used to assist management and conservation practices of natural areas within cities. © 2012 Elsevier Ltd.

abstract = {Leaf fluctuating asymmetry (FA) is considered an important indicator of environmentally induced stress in plants, but the relationship between herbivory and FA levels is not clear. In this study we compared leaf size and shape, leaf area consumed by herbivorous insects, and FA levels between individuals of Heliocarpus pallidus (Tiliaceae) from two adjacent and contrasting habitat types (deciduous and riparian) in the Chamela-Cuixmala tropical dry-forest biosphere reserve. Ten individuals of H. pallidus were collected in each habitat type. Leaf shape was assessed using geometric morphometric techniques. Results indicated statistically significant differences in leaf shape between individuals from the two habitat types. In individuals from the riparian habitat leaf area (mean = 42.3 ± 1.2 cm2), herbivory levels (mean = 25.5% ± 1.8%) and FA levels (mean = 0.38 ± 0.04 cm) were significantly higher than in individuals from the deciduous habitat (17.2 ± 3.5 cm2; 9.6% ± 1.0% and 0.18 ± 0.04 cm, respectively). Within habitats, significant correlations were found between total leaf area and percentage leaf area removed by insects (R2 = 0.92 in riparian habitats},
