“…Parsimony methods are generally thought to perform poorly with AFLP data, most obviously because bands may be lost independently in more than one lineage, giving rise to multiple null alleles that are not identical by descent (Pellmyr et al, 2007).

“…Among other applications, AFLPs are currently widely used to create robust phylogenetic inferences especially within taxa, in which interspecific relationships have been difficult to resolve or when appropriate nuclear genes are scarce (Barluenga et al, 2006;Mendelson and Simons, 2006;Pellmyr et al, 2007). This widespread application is despite the restrictions on the use of AFLP markers in phylogenetic analyses resulting from their unknown mutation characteristics and anonymous nature (Felsenstein, 2004;Koopman, 2005).…”

Pinniped phylogenetic relationships inferred using AFLP markers

Amplified fragment length polymorphisms (AFLPs) are widely used for phylogenetic reconstruction in plants but their use in animal taxa has been limited, and in mammals rare. In addition, their use has been largely limited to shallow relationships amongst species or subspecies. Here, we genotype 23 pinniped species for 310 AFLP markers and find a strong phylogenetic signal, with individuals coclustering within species, and overall a good agreement between our phylogeny and those constructed using mitochondrial DNA and nuclear sequences even at nodes B15 million years old. Although supporting the existing ideas about pinniped relationships, our data shed light on relationships within the hitherto relatively unresolved Phocine species group, and provide further supporting evidence for raising two subspecies of Zalophus californianus, Z. c. californianus and Z. c. wollebaeki, to species level. Plotting AFLP divergence time estimates against those based on both mtDNA and nuclear sequences we find strong linear relationships, suggesting that the different markers are evolving in a clocklike fashion. These data further emphasize the utility of AFLP markers as general tools for phylogenetic reconstruction.

“…However, a recent AFLP-based analysis that included nearly 100 samples representing the most commonly named taxa (Pellmyr et al 2007) identified 34 phylogenetically defined species. In the present study, 96 individuals were selected for PCR and sequencing, representing the 34 species identified by Pellmyr et al (2007) and several putative outgroups, including Agave, Hesperoyucca and Hesperaloe. Whenever possible, samples selected for sequencing were the same individuals included in the AFLP study (Pellmyr et al 2007).…”

Pattern and timing of diversification in Yucca (Agavaceae): specialized pollination does not escalate rates of diversification

The yucca-yucca moth interaction is one of the most well-known and remarkable obligate pollination mutualisms, and is an important study system for understanding coevolution. Previous research suggests that specialist pollinators can promote rapid diversification in plants, and theoretical work has predicted that obligate pollination mutualism promotes cospeciation between plants and their pollinators, resulting in contemporaneous, parallel diversification. However, a lack of information about the age of Yucca has impeded efforts to test these hypotheses. We used analyses of 4322 AFLP markers and cpDNA sequence data representing six non-protein-coding regions (trnT-trnL, trnL, trnL intron, trnL-trnF, rps16 and clpP intron 2) from all 34 species to recover a consensus organismal phylogeny, and used penalized likelihood to estimate divergence times and speciation rates in Yucca. The results indicate that the pollination mutualism did not accelerate diversification, as Yucca diversity (34 species) is not significantly greater than that of its non-moth-pollinated sister group, Agave sensu latissimus (240 species). The new phylogenetic estimates also corroborate the suggestion that the plant-moth pollination mutualism has at least two origins within the Agavaceae. Finally, age estimates show significant discord between the age of Yucca (ca 6-10 Myr) and the current best estimates for the age of their pollinators (32-40 Myr).

“…In total, there now are over one thousand identified plant species from highly divergent families that are known to have coevolved pollination interactions with floral parasites (e.g., Herre et al 2008;Ibanez et al 2009;Kawakita 2010;Pellmyr et al 2007; . The majority of these plant species are pollinated exclusively by their coevolved partners (Dufaÿ and Anstett 2003), but some are visited also by generalist pollinators in some populations (e.g., Reynolds et al 2012;Thompson and Cunningham 2002).…”

Floral Scent Contributes to Interaction Specificity in Coevolving Plants and Their Insect Pollinators

et al. 2014

Chemical defenses, repellents, and attractants are important shapers of species interactions. Chemical attractants could contribute to the divergence of coevolving plant-insect interactions, if pollinators are especially responsive to signals from the local plant species. We experimentally investigated patterns of daily floral scent production in three Lithophragma species (Saxifragaceae) that are geographically isolated and tested how scent divergence affects attraction of their major pollinator-the floral parasitic moth Greya politella (Prodoxidae). These moths oviposit through the corolla while simultaneously pollinating the flower with pollen adhering to the abdomen. The complex and species-specific floral scent profiles were emitted in higher amounts during the day, when these day-flying moths are active. There was minimal divergence found in petal color, which is another potential floral attractant. Female moths responded most strongly to scent from their local host species in olfactometer bioassays, and were more likely to oviposit in, and thereby pollinate, their local host species in no-choice trials. The results suggest that floral scent is an important attractant in this interaction. Local specialization in the pollinator response to a highly specific plant chemistry, thus, has the potential to contribute importantly to patterns of interaction specificity among coevolving plants and highly specialized pollinators.
