text: 'Pedigree and sibship reconstruction are important methods in quantifying
relationships and fitness of individuals in natural populations. Current methods
employ a Markov chain-based algorithm to explore plausible possible pedigrees
iteratively. This provides accurate results, but is time-consuming. Here, we develop
a method to infer sibship and paternity relationships from half-sibling arrays
of known maternity using hierarchical clustering. Given 50 or more unlinked SNP
markers and empirically derived error rates, the method performs as well as the
widely used package Colony, but is faster by two orders of magnitude. Using simulations,
we show that the method performs well across contrasting mating scenarios, even
when samples are large. We then apply the method to open-pollinated arrays of
the snapdragon Antirrhinum majus and find evidence for a high degree of multiple
mating. Although we focus on diploid SNP data, the method does not depend on marker
type and as such has broad applications in nonmodel systems. '

in controlled conditions, and their effect on plant mating. Data were collected
as part of Tom Ellis' PhD thesis , submitted February 2016.\r\n\r\nWe placed a
total of 36 plants in a grid inside a closed organza tent, with a single hive
of commercially bred bumblebees (Bombus hortorum). We used only the yellow-flowered
Antirrhinum majus striatum and the magenta-flowered Antirrhinum majus pseudomajus,

how to deal with snapdragons, I observed pollinators foraging on plants, and recorded
the transitions between plants. Thereafter seeds on plants were allowed to develops.
A sample of these were grown to maturity when their flower colour could be determined,
and they were scored as yellow, magenta, or hybrid."

text: "Data on pollinator visitation to wild snapdragons in a natural hybrid zone,
collected as part of Tom Ellis' PhD thesis (submitted February 2016).\r\n\r\nSnapdragon
flowers have a mouth-like structure which pollinators must open to access nectar.
We placed 5mm cellophane tags in these mouths, which are held in place by the
pressure of the flower until a pollinator visits. When she opens the flower, the
tag drops out, and one can infer a visit. We surveyed plants over multiple days
in 2010, 2011 and 2012.\r\n\r\nAlso included are data on phenotypic and demographic
variables which may be explanatory variables for pollinator visitation."

text: Background and aims Angiosperms display remarkable diversity in flower colour,
implying that transitions between pigmentation phenotypes must have been common.
Despite progress in understanding transitions between anthocyanin (blue, purple,
pink or red) and unpigmented (white) flowers, little is known about the evolutionary
patterns of flower-colour transitions in lineages with both yellow and anthocyanin-pigmented
flowers. This study investigates the relative rates of evolutionary transitions
between different combinations of yellow- and anthocyanin-pigmentation phenotypes
in the tribe Antirrhineae. Methods We surveyed taxonomic literature for data on
anthocyanin and yellow floral pigmentation for 369 species across the tribe. We
then reconstructed the phylogeny of 169 taxa and used phylogenetic comparative
methods to estimate transition rates among pigmentation phenotypes across the
phylogeny. Key Results In contrast to previous studies we found a bias towards
transitions involving a gain in pigmentation, although transitions to phenotypes
with both anthocyanin and yellow taxa are nevertheless extremely rare. Despite
the dominance of yellow and anthocyanin-pigmented taxa, transitions between these
phenotypes are constrained to move through a white intermediate stage, whereas
transitions to double-pigmentation are very rare. The most abundant transitions
are between anthocyanin-pigmented and unpigmented flowers, and similarly the most
abundant polymorphic taxa were those with anthocyanin-pigmented and unpigmented
flowers. Conclusions Our findings show that pigment evolution is limited by the
presence of other floral pigments. This interaction between anthocyanin and yellow
pigments constrains the breadth of potential floral diversity observed in nature.
In particular, they suggest that selection has repeatedly acted to promote the
spread of single-pigmented phenotypes across the Antirrhineae phylogeny. Furthermore,
the correlation between transition rates and polymorphism suggests that the forces
causing and maintaining variance in the short term reflect evolutionary processes
on longer time scales.

text: Hybrid zones represent evolutionary laboratories, where recombination brings
together alleles in combinations which have not previously been tested by selection.
This provides an excellent opportunity to test the effect of molecular variation
on fitness, and how this variation is able to spread through populations in a
natural context. The snapdragon Antirrhinum majus is polymorphic in the wild for
two loci controlling the distribution of yellow and magenta floral pigments. Where
the yellow A. m. striatum and the magenta A. m. pseudomajus meet along a valley
in the Spanish Pyrenees they form a stable hybrid zone Alleles at these loci recombine
to give striking transgressive variation for flower colour. The sharp transition
in phenotype over ~1km implies strong selection maintaining the hybrid zone. An
indirect assay of pollinator visitation in the field found that pollinators forage
in a positive-frequency dependent manner on Antirrhinum, matching previous data
on fruit set. Experimental arrays and paternity analysis of wild-pollinated seeds
demonstrated assortative mating for pigmentation alleles, and that pollinator
behaviour alone is sufficient to explain this pattern. Selection by pollinators
should be sufficiently strong to maintain the hybrid zone, although other mechanisms
may be at work. At a broader scale I examined evolutionary transitions between
yellow and anthocyanin pigmentation in the tribe Antirrhinae, and found that selection
has acted strate that pollinators are a major determinant of reproductive success
and mating patterns in wild Antirrhinum.

text: Almost all species of the orchid genus Ophrys are pollinated by sexual deception.
The orchids mimic the sex pheromone of receptive female insects, mainly hymenopterans,
in order to attract males seeking to copulate. Most Ophrys species have achromatic
flowers, but some exhibit a coloured perianth and a bright, conspicuous labellum
pattern. We recently showed that the pink perianth of Ophrys heldreichii flowers
increases detectability by its pollinator, males of the long-horned bee Eucera
berlandi. Here we tested the hypothesis that the bright, complex labellum pattern
mimics the female of the pollinator to increase attractiveness toward males. In
a dual-choice test we offered E. berlandi males an O. heldreichii flower and a
flower from O. dictynnae, which also exhibits a pinkish perianth but no conspicuous
labellum pattern. Both flowers were housed in UV-transmitting acrylic glass boxes
to exclude olfactory signals. Males significantly preferred O. heldreichii to
O. dictynnae flowers. In a second experiment, we replaced the perianth of both
flowers with identical artificial perianths made from pink card, so that only
the labellum differed between the two flower stimuli. Males then chose between
both stimuli at random, suggesting that the presence of a labellum pattern does
not affect their choice. Spectral measurements revealed higher colour contrast
with the background of the perianth of O. heldreichii compared to O. dictynnae,
but no difference in green receptor-specific contrast or brightness. Our results
show that male choice is guided by the chromatic contrast of the perianth during
the initial flower approach but is not affected by the presence of a labellum
pattern. Instead, we hypothesise that the labellum pattern is involved in aversive
learning during post-copulatory behaviour and used by the orchid as a strategy
to increase outcrossing.
