Identifying and managing Cercospora leaf blight in soybean: From scouting to best management practices

Crop, Forage &Turfgrass Management, Volume 12, Issue 1, June 2026.
Abstract Maximizing soybean [Glycine max (L.) Merr.] yield requires effective management of Cercospora leaf blight (CLB), a significant foliar disease that can reduce productivity and grain quality. The impact of CLB is particularly notable in regions such as the mid‐southern United States, where species of Cercospora, predominantly C. cf. flagellaris,

Widespread Lateral Transmission in Fergusonina Galling Flies (Diptera: Fergusoninidae) and Their Obligate Nematode Mutualists Does Not Preclude an Overall Pattern of Cospeciation

Ecology and Evolution, Volume 16, Issue 6, June 2026.
The biology of gall‐forming fergusoninid flies and their obligate nematode mutualists suggests strict vertical transmission of nematodes between fly generations. Using mitochondrial sequence data to associate fly and nematode haplotypes, we found widespread intraspecific horizontal transfer in multiple species.

Complex History of Organellar Introgression in Nothofagus Trees: Chloroplast and Mitochondrial Capture Facilitated by Natural Selection

Ecology and Evolution, Volume 16, Issue 6, June 2026.
Field photograph of an ancient Nothofagus tree covered with epiphytic lichens in the Patagonian temperate rainforest. This genus serves as a key model for investigating organellar introgression and evolutionary genomics in South America. ABSTRACT Hybridization is widespread across diverse groups of organisms, and in some cases, organellar genomes of ...

Observations of Modified Polyps and Polyp Leaves in Sea Pens (Cnidaria: Octocorallia): The Cases of Ptilella and Pennatula

Ecology and Evolution, Volume 16, Issue 6, June 2026.
We describe unusual and mostly unreported morphological traits on colonies of the deep‐water sea pens Ptilella and Pennatula from the Northwest Atlantic, namely the presence of hypertrophied polyps, split polyp leaves, and autozooids budding on the surface of polyp leaves (as opposed to the edges). ABSTRACT Here we describe unusual morphological traits

Resilience and plant growth forms 40 years after a volcanic disturbance

Ecosphere, Volume 17, Issue 6, June 2026.
Abstract Resilience represents a critical concept in ecology; yet, quantitative assessment of resilience in response to disturbance is rare, even for widely recognized growth forms. Plant groups based on deciduousness, clonality, morphology, and Raunkiaer life form could predict inertia to major disturbances and subsequent resilience.

The seed bank created by the dung of large herbivores drives seed circulation in an alpine meadow

Ecosphere, Volume 17, Issue 6, June 2026.
Abstract Seed circulation (i.e., sexual reproduction) is vital for the regeneration of aboveground grassland vegetation (AGV). It occurs in several steps: seed production (seed rain, SR), dispersal (endozoochory, i.e., dung seed bank, DSB), formation of the soil seed bank (SSB), germination, seedling growth, and establishment of adult plants.
