Traversing the effects of ploidy changes in different Eragrostis curvula genotypes through high-throughput RNA sequencing. [PDF]

open access: yesPlant Genome
Abstract Polyploidization has played a key role in plant genome evolution. Eragrostis curvula (Schrad.) Ness, a perennial forage grass species of the Poaceae family, is an excellent model for investigating genome duplication due to its natural variation in ploidy levels.

Resource suitability drives low use of avian-excavated tree cavities: A multi-state occupancy dynamics approach. [PDF]

open access: yesJ Anim Ecol
Birds that nest in tree cavities are sometimes dependent on a few cavity‐excavating bird species to make nesting sites available. Such interdependency, however, does not always materialize because excavated cavities may be unsuitable for continued use, even when available for several years after excavation.

Agrestal Environments and Maternal Genetic Effects Weaken the Ecological Barriers for Crop to Wild Introgression in Sunflower. [PDF]

open access: yesEcol Evol
We highlight how agrestal environments and maternal effects may facilitate the adaptation of crop‐wild hybrid sunflower to agroecosystems. We present two consecutive years of data on diverse wild and reciprocal crop‐wild hybrid sunflower populations planted in three contrasting, ruderal or agrestal, environments. We found that (i) agrestal environments

Cumulative Extreme Events Threaten Penguin Habitats Across the Southern Hemisphere. [PDF]

open access: yesGlob Chang Biol
This study examines how multiple extreme events overlap across the Southern Hemisphere, focusing on hotspots of 18 penguin species across both land and sea. African, Snares, Emperor, Adélie and Galápagos penguins experience the greatest combined exposure, and most species are projected to face more frequent extremes if current trends persist.
