Simulating Ips typographus L. outbreak dynamics and their influence on carbon balance estimates with ORCHIDEE r8627 [PDF]

open access: yesGeoscientific Model Development
New (a)biotic conditions resulting from climate change are expected to change disturbance dynamics, such as windthrow, forest fires, droughts, and insect outbreaks, and their interactions.

Patogeni žuželk s poudarkom na patogenih podlubniih (COL., Scolytidae: Ips typographus L.) : preliminarni rezultati o izolaciji entomopatogenih gliv iz dveh smrekovih podlubnikov v Sloveniji [PDF]

open access: yes, 2017
This paper deals with the most important groups of insect pathogens, i.e. viruses, bacteria, fungi, nematodes and protozoans (microsporidia). We describe their basic characteristics, virulence, method of infecting or attackon the host, signs of illnesses

Ips acuminatus (Gyllenhal) in the Czech Republic: Flight dynamics and adult population structure

open access: yesPhysiological Entomology, Volume 51, Issue 1, Page 136-146, March 2026.
Ips acuminatus exhibits a univoltine life cycle in Central Europe and no full second generation in midsummer. The sex ratio shifts from male‐biased in spring to slightly female‐biased with the season, with over 90% of females mated. Among the pheromone lures tested, the ACP was most attractive, and combining ACP and PH lures could be used for effective

Modeling stratified dispersal in forest pests: A case study of the mountain pine beetle in Alberta

open access: yesEcology, Volume 107, Issue 2, February 2026.
Abstract Forest pests pose critical threats to forest ecosystems worldwide, yet accurately predicting their spatial spread remains challenging due to complex dispersal behaviors, weather effects, and the inherent difficulty of tracking small organisms across large landscapes.

Geographical variability of sprucebark beetle development under climate change in the Czech Republic

open access: yesJournal of Forest Science, 2011
Climate change is expected to influence the distribution and population dynamics of many insect pests, with potential severe impacts on forests. Spruce bark beetle Ips typographus (L.) (Col.: Curculionidae, Scolytinae) is the most important forest insect

Taxonomy and pathogenicity of ophiostomatoid fungi associated with bark beetles infesting conifers in Japan, with special reference to those related to subalpine conifers [PDF]

open access: yes, 2017
Ophiostomatoid fungi are ambiguous. They belong to the Ascomycota, and were formerly treated as one family and grouped in one genus, but molecular phylogenic studies have shown that they are divided into two orders and their generic classification must ...

Forest Reorganization Sustains Carbon Sequestration Under Climate Change

open access: yesGlobal Biogeochemical Cycles, Volume 40, Issue 2, February 2026.
Abstract Forests currently mitigate anthropogenic climate change by sequestering substantial amounts of carbon, but future carbon dynamics are expected to vary across the temperate forest biome. Previously cold‐limited ecosystems with low disturbance activity could increase their carbon uptake, while water‐limited ecosystems with high disturbance ...

Outbreak dynamics of the spruce bark beetle Ips typographus in time and space [PDF]

open access: yes, 2015
The European spruce bark beetle Ips typographus (L.) is one of the most important pests of mature Norway spruce Picea abies (Karst.) in Europe. Outbreaks (periods with large-scale beetle-caused tree mortality) are often triggered by large-scale ...
