A clipart image of a plant representing the weed palmer amaranth surrounded by three additional images. In the upper left, a circle with three arrows on it represents extrachromosomal circular DNA containing the GS2 and EPSPS genes. On the right, a section labeled "Metabolic herbicide resistance" depicts an irregular shape representing a cytochrome P450 protein containing a heme domain shown as facilitating the metabolism of the chemical bentazon by adding a hydroxyl group. In the lower left, a section labeled "Horizontal gene transfer in parasitic plants" depicts a clipart of a mustard plant connected to the amaranth by tendrils of the vinelike dodder plant.

Flower color variation in Digitalis purpurea comprised violet, pink, and white morphs that were distinguishable in bee vision, whereas the inner nectar guides remained largely conserved across morphs, potentially limiting pollinator discrimination. Bumblebees were the main pollinators in all populations, but visitation patterns were population-specific, and morph frequencies were not associated with soil composition despite regional differences; only soil phosphorus was slightly lower beneath violet individuals. Reproductive fitness varied among populations but not consistently among color morphs, indicating that floral color variation is not driven by pollinators or soil conditions and is more likely maintained by local or neutral processes.

The 2D surface geometry of the shoot and root apical meristems of diverse vascular plants was analyzed using six different non-linear equations to assess which among the six provided the best mathematical representation. One among the six equations (the superparabolic equation) emerged as superior to the rest, although none was canonically correct.

Photo of the experimental setup used to evaluate the comparative response to herbivory across the Brachypodium species complex. The picture was taken during the feeding experiment, in which the authors placed one locust on multiple lines of diploid Brachypodium distachyon, B. stacei, and B. hybridum allopolyploid. Locusts were allowed to feed for 48 h, after which damage and fitness were evaluated.

The movement of seeds in space-time. The hypothetical two-dimensional space shows how habitat suitability varies across space and time. Seeds can avoid unsuitable conditions in the present by (i) dispersing to a more suitable location or (ii) remaining dormant until conditions change. However, a mix of both processes (iii) can also give individuals a great chance of reaching a suitable habitat. Gray-shaded areas represent hypothetical distributions showing the probability of dispersing to distance x and of escaping dormancy at time t. In our example, the probability of observing outcome iii is greater than observing outcomes i or ii.

Conceptual diagram of touch-sensitive stigma movements in Mazus miquelii. Higher temperatures accelerate both temporary closure and reopening. whereas permanent (irreversible) closure tracks pollination progress: greater pollen deposition and faster pollen-tube growth accelerate permanent closure, while pollen-tube position is positively associated with the time to permanent closure. Pollen source shows no detectable effect.

Sphagnum magniae, from Sandy Run Savanna Natural area, Onslow County, North Carolina (20 Sept. 2025, B. Aguero 21498, voucher at DUKE). This species, one of four in the S. magellanicum complex in eastern North America, is distributed mainly in the coastal plain from New Jersey to Florida and along the Gulf coast. S. magniae is closely related to the cold-temperate to boreal S. diabolicum and all plants from New Jersey to North Carolina are genetically admixed between these two species.
