Are they two seeds in a pod? Comparing seed rain recovery in grasslands using artificial grass carpets vs sticky traps (by @llseedsull.bsky.social, DeSiervo, Kahan & Shoemaker)

Comparison of two seed rain trap methods in the field: a sticky trap (a Petri dish with a sticky substance sprayed on it) and an artificial grass carpet. Both have known numbers of grassland seeds placed on them.

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.

The sleeping giant needs coffee: Overlooked areas for integrating plant #ecophysiology & evolutionary biology

doi.org/10.1002/ajb2...

#botany #plantscience #ecology #evolution
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.

#Phylogenomics, ecomorphological #evolution, & historical biogeography in Deuterocohnia (Bromeliaceae: Pitcairnioideae)

New #AJB research by Bing Li, Nicole Schütz, Kurt Weising, Georg Zizka, Jacob Landis & Thomas Givnish

doi.org/10.1002/ajb2... #botany #plantscience #Neotropics
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.
