“…This modification might be associated with changes in feeding behaviours between insects and passerine birds. These birds do not land in the flowers (as most insects do), but rather they forage from the ground, a nearby branch or by hovering [12,18,19]. Thus, the main mechanical interaction occurs when the bird collects nectar from the flower.…”

Pollinator shifts drive petal epidermal evolution on the Macaronesian Islands bird-flowered species

Pollinator shifts are considered to drive floral trait evolution, yet little is still known about the modifications of petal epidermal surface at a biogeographic region scale. Here we investigated how independent shifts from insects to passerine birds in the Macaronesian Islands consistently modified this floral trait (i.e. absence of papillate cells). Using current phylogenies and extensive evidence from field observations, we selected a total of 81 plant species and subspecies for petal microscopy and comparative analysis, including 19 of the 23 insular species pollinated by opportunistic passerine birds (Macaronesian bird-flowered element). Species relying on passerine birds as the most effective pollinators (bird-pollinated) independently evolved at least five times and in all instances associated with a loss of papillate cells, whereas species with a mixed pollination system (birds plus insects and/or other vertebrates) evolved at least five times in Macaronesia and papillate cells were lost in only 25% of these transitions. Our findings suggest that petal micromorphology is a labile trait during pollinator shifts and that papillate cells tend to be absent on those species where pollinators have limited mechanical interaction with flowers, including opportunistic passerine birds that forage by hovering or from the ground.

“…Damage from sucking insects causes progressive wilting of reproductive stalks whereas damage from biting insects leads to the immediate loss of flowers. Evidence indicates that florivory reduces female fitness by direct consumption of ovules, and it could reduce male fitness directly by the lost of pollen grains and indirectly by reducing the attractiveness of flowers (Krupnick & Weis 1998;Mothershead & Marquis 2000;McCall 2008;Cascante-Marín et al 2009;Zangerl & Berenbaum 2009;Rodríguez-Rodríguez & Valido 2011;de Jager & Ellis 2013). Using morphometric techniques we have gathered information for P. moranensis indicating that flower shape is a trait under phenotypic selection (in preparation).…”

Identifying the factors that affect a plant's probability of being found and damaged by herbivores has been a central topic in the study of herbivory. Although herbivory could have important negative consequences on carnivorous plants, their interaction with herbivores remains largely unexplored. We evaluated the effect of spatial variation in light environment (sunny, shade and full-shade sites) on the pattern of leaf herbivory and florivory of the carnivorous plant Pinguicula moranensis. Plants' overall probability of leaf damage was high (74.24%). Mean herbivory was four times higher in the sunny and shade sites than the observed in the full-shade site. Nearly 8% of plants suffered damage to reproductive structures, although the probability of florivory was similar among sites. Discussion addressed the inter-site variation in mean herbivory considering the effect of light exposure and the impact that herbivory could have on fitness components of this carnivorous plant.

“…This decrease in available resources following defoliation can reduce, for example, survival, growth, Xower production, fruit maturation and seed production (e.g. Mendoza has been shown to reduce reproductive success directly by decreasing fruit and seed production (Wallace and O'Dowd 1989;Rose et al 2005;Rodríguez-Rodríguez and Valido 2011), but also indirectly by disrupting pollinator visitation and eYciency ; Mothershead and Marquis 2000;Cardel and Koptur 2010). Hence, this type of damage can have an equal or greater negative eVect on plant Wtness compared to leaf damage.…”

Herbivores may damage both leaves and reproductive structures, and although such combined damage may affect plant fitness non-additively, this has received little attention. We conducted a 2-year field experiment with a factorial design to examine the effects of simulated leaf (0, 12.5, 25, or 50% of leaf area removed) and inflorescence damage (0 vs. 50% of inflorescences removed) on survival, growth and reproduction in the perennial herb Arabidopsis lyrata. Leaf and inflorescence damage negatively and independently reduced flower, fruit and seed production in the year of damage; leaf damage also reduced rosette size by the end of the first season and flower production in the second year. Leaf damage alone reduced the proportion of flowers forming a fruit and fruit production per plant the second year, but when combined with inflorescence damage no such effect was observed (significant leaf × inflorescence damage interaction). Damage to leaves (sources) caused a greater reduction in future reproduction than did simultaneous damage to leaves and inflorescences (sinks). This demonstrates that a full understanding of the effects of herbivore damage on plant fitness requires that consequences of damage to vegetative and reproductive structures are evaluated over more than 1 year and that non-additive effects are considered.
