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.

Duckweeds (Lemna minor sensu lato) cover the surface of the upper region of Mill Pond in Durham, NH, together with closely related species (Wolffia sp. and Spirodela polyrhiza). Duckweeds in this region exhibited weak local adaptation to biotic (microbiome) and abiotic (water) features of their environment combined.

Graphic announcing new AJB Synthesis article by Haley Branch.
Methodological illustration for asking whether X affects plants. “Question” provides an example of a question that both ecologists and evolutionary biologists ask, with categories of traits often of interest. “Experiment” shows trait examples and comparisons (populations, environmental, across time). Types of traits are where evolutionary biologists could expand their breadth. “Outcome” describes lasting effects of whether X affects traits to the point that it is passed on and contributes to future generations or it leads to extinction. “Outcomes” is where ecophysiologists could expand their work. Images courtesy of Dr. Stefanie Sultmanis (vein density), Dr. Beatrice Harrison Day (root section), and Dr. Vanessa Tonet (leaf cavitation).

Deuterocohnia is a small genus of bromeliads, with only 17 species, but has radiated into an extraordinary range of habitats, from sea level on the coasts of Chile and Peru coasts to 3900 m elevation in the Andes of Bolivia and Argentina. Li et al. use sequences of over 1800 nuclear genes and whole plastomes to infer relationships, reconstruct the evolution of morphology and ecology, and evaluate historical biogeography. They found rapid adaptive divergence, two convergent origins of the cushion-plant habit, recurrent effects of the Rio Pilcomaya barrier on speciation and chloroplast capture. Deuterocohnia arose in southeastern Bolivia, and—as shown by this stochastic mapping—repeatedly evolved up- and downslope into other habitats from Andean Yungas on steep slopes at mid-elevation.
