Dimorphic enantiostyly and its function for pollination by carpenter bees in a pollen-rewarding Caribbean bloodwort. [PDF]

Am J Bot
Abstract Premise Flowers that present their anthers and stigma in close proximity can achieve precise animal‐mediated pollen transfer, but risk self‐pollination. One evolutionary solution is reciprocal herkogamy. Reciprocity of anther and style positions among different plants (i.e., a genetic dimorphism) is common in distylous plants, but very rare in

Separating Sampling Bias From Abundance Shows That Different Methods Catch Different Wild Bees. [PDF]

Ecol Evol
Comparing community sampling methods' relative taxonomic biases is critical to interpreting the data they collect, but measuring bias explicitly is difficult when methods also produce different sample sizes. Here, we control for absolute abundance while comparing sample composition and richness of three common methods for sampling wild bee communities.

Generalization for both diurnal and nocturnal pollination in the mass-flowering desert geophyte Nerine laticoma (Amaryllidaceae). [PDF]

Plant Biol (Stuttg)
Both diurnal and nocturnal pollinators are important in the desert plant Nerine laticoma. Abstract The evolutionary limits to generalization in plant pollination systems are often determined by trade‐offs in which adaptations to one set of flower visitors reduces the effectiveness of another set of visitors.

Fine-tuning the buzz: comparing visitation frequency and pollination effectiveness in plant-pollinator networks. [PDF]

New Phytol
Summary Ecological network approaches have advanced our understanding of how species interactions influence community and evolutionary dynamics. However, a key limitation is that most network analyses rely solely on visitation data, often overlooking functional aspects of interactions.
