“…Likewise, partial or total petal removal in Loasa tricolor (Loasaceae) had contrasting effects on pollination rates, indicating a dose‐dependent response of pollinators to flower herbivory (Cares‐Suárez et al . ). These results differ from those obtained by Cuartas‐Domínguez & Medel (), who reported that phenotypic modification of the lateral sepals and the labellar lobe of Chloraea bletioides (Orchidaceae) had no effect on male and female fitness functions.…”

Pollination in the Chilean Mediterranean‐type ecosystem: a review of current advances and pending tasks

We conducted a systematic review of the scientific literature published on plant-pollinator interactions, from both the plant and pollinator perspective, in the Chilean Mediterranean-type ecosystem (MTE hereafter). Our search identified 69 published papers on 235 native plant species from 62 families. Less than 7.9% of the flowering species inhabiting the Chilean Mediterranean have been studied, and most studies were restricted to only one locality and one reproductive season. The geographic location of the studies differed from a random pattern, showing two well-defined areas where most studies were conducted. Likewise, most studies in the Andes Range were performed above 2000 m a.s.l. The number of species of flower visitor per plant species was low (4.25 ± 0.22), which probably results from the historical and biogeographic isolation of Chile. This literature survey shows that studies relating floral traits with pollinator attraction and plant reproduction are the most frequent topics of research, reaching 37.6% of studies, followed by studies that examine pollination in relation to human impact (16.1%), micro- and macroevolution (14.0%), relationships between pollination and other ecological interactions (10.8%), community and network assessments (11.8%), and effects of abiotic variables on pollination interactions (9.7%). Our review highlights a lack of research on the effects of pollination for anthropogenic land use especially as agricultural practice is one of the most salient features of the Chilean MTE. Future directions to increase our understanding of the role of plant-pollinator relationships for biodiversity maintenance should include: to extend the taxonomic and geographic scope of research, to increase the number of spatial and temporal replicates, to increase the number of studies on pollination networks as they provide estimates of community complexity and putative stability, to develop studies that estimate the importance of pollination for plant demographic parameters and conservation, and to conduct studies that estimate the ecological service provided by Chilean native pollinators for crop yield and sustainable agriculture.

“…Florivory often reduces flower size ( Strauss and Whittall 2006 ) and nectar production ( Krupnick et al 1999 ; Strauss and Whittall 2006 ), both of which may reduce pollinator visitation as many pollinators tend to prefer larger flowers and greater nectar production ( Bell 1985 ; Galen 1989 ; Kudoh and Whigham 1998 ; Krupnick et al 1999 ; Arista and Ortiz 2007 ; Shumitt 2014 ). An increasing number of studies suggest that floral damage can indeed decrease pollinator visitation ( Karban and Strauss 1993 ; Pohl et al 2006 ; Ashman and Penet 2007 ; Penet et al 2009 ; Cardel and Koptur 2010 ; Sõber et al 2010 ; Cares-Suárez et al 2011 ), potentially resulting in reduced pollination and plant fitness ( Krupnick and Weis 1999 ; Mothershead and Marquis 2000 ; Leavitt and Robertson 2006 ; McCall and Irwin 2006 ; Strauss and Whittall 2006 ; Sánchez-Lafuente 2007 ; Carezza et al 2011 ).…”

Florivory and pollinator visitation: a cautionary tale

Floral herbivory can make flowers less attractive to pollinators. To study the effect of floral herbivory on pollination in the hummingbird-pollinated sticky monkeyflower, we conducted field observations and experiments. We used two indicators of pollinator visitation: stigma closure and the presence of microorganisms in floral nectar. The field observations revealed that stigma closure was less frequent in damaged flowers than in intact flowers. In the experiments, however, floral damage did not decrease stigma closure or microbial detection. These results tell a cautionary tale: a negative association between florivory and pollinator visitation can be observed without florivory affecting pollinator visitation.

“…Recruitment of those plants depending on pollination vectors (usually autoincompatible plants) is expected to diminish because of the herbivory, both directly (tissue damage) and indirectly due to the reduction of the pollinator visit rates [69,70,76], modifying plant fitness in many possible ways [77]. Moreover, the damage of certain key flower structure (e.g., nectar guides) could enhance this situation [78], especially if the flower damage goes beyond a damage threshold that makes the pollinators reluctant to visit the flowers [79].…”

Plant-animal interactions are a key component for biodiversity maintenance, but they are currently threatened by human activities. Habitat fragmentation might alter ecological interactions due to demographic changes, spatial discontinuities, and edge effects. Also, there are less evident effects of habitat fragmentation that potentially alter selective forces and compromise the fitness of the interacting species. Changes in the mutualistic and antagonistic interactions in fragmented habitats could significantly influence the plant reproductive output and the fauna assemblage associated with. Fragmented habitats may trigger contemporary evolution processes and open new evolutionary opportunities. Interacting parties with a diffuse and asymmetric relationship are less susceptible to local extinction but more prone to evolve towards new interactions or autonomy. However, highly specialized mutualisms are likely to disappear. On the other hand, ecological interactions may mutually modulate their response in fragmented habitats, especially when antagonistic interactions disrupt mutualistic ones. Ecoevolutionary issues of habitat fragmentation have been little explored, but the empiric evidence available suggests that the complex modification of ecological interactions in fragmented habitats might lead to nonanalogous communities on the long term.
