Predation pressure varies vertically, with highest arthropod predation in the understory and highest bird predation in the canopy. Light availability differs across vertical strata, but predation patterns are more strongly influenced by height and forest structure than by light gradients.

Interactions of Spring Cereal Genotypic Attributes and Recovery of Grain Yield After Defoliation
Dual-purpose crops are grazed during their vegetative phase and allowed to regrow to produce grain. Grazing slow-developing winter cereals (wheat, barley, and triticale) is common, but there is also potential to graze faster-developing spring cereals ...

Invasion of winter moth in New England: Effects of defoliation and site quality on tree mortality. [PDF]
Widespread and prolonged defoliation by the European winter moth, Operophtera brumata L., has occurred in forests of eastern Massachusetts for more than a decade and populations of winter moth continue to invade new areas of New England.

A protracted phenology: Post‐diapause larval development of a threatened butterfly
Larval survival during diapause was high; hibernaculum webs were mostly located near Succisa pratensis plants, which often retained vital leaves through winter. Post‐diapause developmental time varied strongly depending on exposure to different microclimates, being reduced by litter cover, solar radiation and a higher heat load index.

ABSTRACT Rachiplusia nu, known as the sunflower looper (SFL) and belonging to the Plusiinae subfamily, is a major defoliator of soybeans, sunflowers and other horticultural crops across southern South America. This species has recently expanded to central and northern regions of Brazil, becoming a key soybean pest.

De novo stolon organogenesis in potato leaf callus elicited by Agrobacterium tumefaciens stimulus
Agrobacterium tumefaciens triggers stolon regeneration from potato leaf callus independent of T‐DNA insertion, suggesting a strategy to reprogram callus identity and expand the potential of tissue regeneration. ABSTRACT Plant cells can undergo cellular reprogramming, enabling pluripotent callus formation from excised leaves.
