Abstract Quantifying tree defoliation by insects over large areas is a major challenge in forest management, but it essential ecosystem assessments of disturbance and resistance against herbivory. However, the trajectory from leaf‐flush to insect refoliation broadleaf trees highly variable. Its tracking requires high temporal‐ spatial‐resolution data, particularly fragmented forests. In unique replicated field experiment manipulating gypsy moth Lymantria dispar densities mixed‐oak forests,...
Abstract 1. Gypsy moth outbreaks cause severe defoliation in Holarctic forests, both North America where it is invasive, and its native range Eurasia. Defoliation can hamper timber production impact ecological communities processes. Aerial insecticide applications are regularly performed outbreak areas to mitigate economic losses. These operations be financially costly harmful non‐target species may disrupt interaction networks. However, replicated studies of the relative impacts gypsy...
Outbreaks of the spongy moth Lymantria dispar can have devastating impacts on forest resources and ecosystems. Lepidoptera-specific insecticides, such as Bacillus thuringiensis var. kurstaki (BTK) tebufenozide, are often deployed to prevent heavy defoliation canopy. While it has been suggested that using BTK poses less risk non-target Lepidoptera than leaving an outbreak untreated, in situ testing this assumption impeded by methodological challenges. The trade-offs between insecticide use...
In this study, we investigate the immediate and short-term consequences of defoliation by spongy moth Lymantria dispar on secondary growth oaks (Quercus robur L. Quercus petraea (Matt.) Liebl.), including interplay between water availability during period within a large-scale field experiment in south-eastern Germany. Furthermore, impact oak is explored retrospectively based tree core measurements. Within filed experiment, 880 44 oak-dominated stands was monitored using permanent girth tapes...
Abstract Rachel Carson's warning of a silent spring directed attention to unwanted side effects pesticide application. Though her work led policies restricting insecticide use, various insecticides currently in use affect nontarget organisms and may contribute population declines. The tebufenozide is used control defoliating Lepidoptera oak forests harboring rich insect faunas. Over 3 years, we tested the effect its aerial application on bird populations with autonomous sound recorders...
Defoliation, a manifestation of foliage loss from trees, arises various influences: animals, microbes or drought stress. Removing the principal photosynthetical part tree has been shown to markedly influence growth across an array forest ecosystems.Among these, European oak woodlands, integral providers essential ecosystem services and substantial contributors carbon sequestration, are particularly noteworthy for their climate stability. Oaks characteristically counteract leaf by instigating...
ABSTRACT Functional exhaustion of T cells in cancer and persistent infections is characterized by the upregulation inhibitory receptors, progressive decline cytokine secretion impaired cytolytic activity. Terminally exhausted are steadily replenished a precursor population (Tpex) with phenotypic features memory stem-like capacity to self-renew. However, metabolic principles Tpex maintenance regulatory circuits that control their progeny remain incompletely understood. Using combination...
Eruptive population dynamics of forest insect species regularly attract the interest ecologists but also often evoke debates among stakeholders concerning threats that outbreaks or pest control activities pose to communities including insectivorous birds. Lymantria dispar is most serious native defoliator in mixed oak-broadleaf forests Central Europe. To investigate impact L. density and aerial application insecticide Mimic (tebufenozide) on nest box success cavity nesting birds, we deployed...
