Floral specialization and angiosperm diversity: phenotypic divergence, fitness trade-offs and realized pollination accuracy
Armbruster, William Scott (Journal article; Peer reviewed, 2014)Plant reproduction by means of flowers has long been thought to promote the success and diversification of angiosperms. It remains unclear, however, how this success has come about. Do flowers, and their capacity to have ... -
Inbreeding effects in a mixed-mating vine: Effects of mating history, pollen competition and stress on the cost of inbreeding
Opedal, Øystein Hjorthol; Armbruster, William Scott; Pelabon, Christophe (Journal article; Peer reviewed, 2015)Inbreeding depression is assumed to be a central factor contributing to the stability of plant mating systems. Predicting the fitness consequence of inbreeding in natural populations is complicated, however, because it may ... -
Intersexual conflict over seed size is stronger in more outcrossed populations of a mixed-mating plant
Raunsgard, Astrid; Opedal, Øystein Hjorthol; Ekrem, Runa K; Wright, Jonathan; Bolstad, Geir Hysing; Armbruster, William Scott; Pelabon, Christophe (Journal article; Peer reviewed, 2018)In polyandrous species, fathers benefit from attracting greater maternal investment toward their offspring at the expense of the offspring of other males, while mothers should usually allocate resources equally among ... -
Novel microsatellite markers for Dalechampia scandens(Euphorbiaceae) and closely related taxa:application to studying a species complex
Falahati-Anbaran, Mohsen; Stenøien, Hans K.; Bolstad, Geir Hysing; Hansen, Thomas F; Pérez‐Barrales, Rocio; Armbruster, William Scott; Pelabon, Christophe (Journal article; Peer reviewed, 2016)We developed novel microsatellite markers for D alechampia scandens L. (Euphorbiaceae). The target plants belong to a distinct, but undescribed, species in the D . scandens species complex, characterized by small resin-producing ... -
Rainfall seasonality predicts the germination behaviour of a tropical dry-forest vine
Martins, Adriana A.; Opedal, Øystein Hjorthol; Armbruster, William Scott; Pelabon, Christophe (Journal article; Peer reviewed, 2019)Seed dormancy is considered to be an adaptive strategy in seasonal and/or unpredictable environments because it prevents germination during climatically favorable periods that are too short for seedling establishment. ... -

Using ecological context to interpret spatiotemporal variation in natural selection
Albertsen, Elena; Opedal, Øystein Hjorthol; Bolstad, Geir Hysing; Pérez-Barrales, Rocío; Hansen, Thomas F; Pelabon, Christophe; Armbruster, William Scott (Peer reviewed; Journal article, 2020)Spatiotemporal variation in natural selection is expected, but difficult to estimate. Pollinator‐mediated selection on floral traits provides a good system for understanding and linking variation in selection to differences ...
