Towards an understanding of the evolutionary role of fire in animals

Evolutionary Ecology (2018), pp. 1-13,


Wildfires underpin the dynamics and diversity of many ecosystems worldwide, and plants show a plethora of adaptive traits for persisting recurrent fires. Many fire-prone ecosystems also harbor a rich fauna; however, knowledge about adaptive traits to fire in animals remains poorly explored. We review existing literature and suggest that fire is an important evolutionary driver for animal diversity because (1) many animals are present in fire-prone landscapes and may have structural and phenotypic characters that contribute to adaptation to these open ...


Pest categorisation of Ips typographus

EFSA Journal, Vol. 15, No. 7. (July 2017), 4881,


The Panel on Plant Health performed a pest categorisation of the eight-toothed spruce bark beetle, Ips typographus L. (Coleoptera: Curculionidae, Scolytinae), for the EU. I. typographus is a well-defined and distinguishable species, recognised mainly as a pest of spruce (Picea spp.) in Eurasia. It also attacks other conifers such as Abies spp., Larix spp., Pinus spp. and Pseudotsuga menziesii. Native to Eurasia, I. typographus has spread from the native range of spruce to new areas in Eurasia where spruce has been ...

The status of our scientific understanding of lodgepole pine and mountain pine beetles - A focus on forest ecology and fire behavior

Global Fire Initiative technical report, Vol. 2008, No. 2. (2008), pp. 1-13


A synthesis of our current knowledge about the effects of the mountain pine beetle epidemic on lodgepole pine forests and fire behavior, with a geographic focus on Colorado and southern Wyoming. [Excerpt: Implications for future forests] Models for predicting future climates have progressed dramatically in recent years, but their accuracy is questionable for planning purposes, particularly at local levels. Nonetheless, model predictions suggest significant alterations in climate from past observed patterns. These predictions are supported by recent climate events that themselves had largely been predicted several years ago. Therefore, the potential ...


Disturbance and the carbon balance of US forests: a quantitative review of impacts from harvests, fires, insects, and droughts

Global and Planetary Change, Vol. 143 (August 2016), pp. 66-80,


[Highlights] [::] Available data suggest harvest is the leading disturbance impact on C in US forests then fire, windthrow, insects, and droughts. [::] Disturbances in US forests lead to the loss of at least 200 Tg C in live biomass each year on average. [::] Regrowth roughly balances disturbance emissions, with growth enhancements contributing significantly to the net change in forest carbon. [::] Natural disturbance events are likely to rise in the future, leading to net release of forest carbon. [Abstract] Disturbances are a major determinant of ...

Dutch elm disease and elm bark beetles: a century of association

iForest - Biogeosciences and Forestry, Vol. 8, No. 2. (01 April 2015), pp. 126-134,


Bark beetles of the genus Scolytus Geoffroy are the main vectors of the fungus Ophiostoma ulmi s.l., which causes the Dutch elm disease. The large and small elm bark beetles - S. scolytus (F.) and S. multistriatus (Marsham), respectively - are the most common and important species spreading the pathogen worldwide. The success of the pathogen-insect interactions is mainly due to the characteristic reproductive behavior of the elm bark beetles, which, however, largely depends on the occurrence of infected trees. During ...


Unraveling the drivers of intensifying forest disturbance regimes in Europe

Global Change Biology, Vol. 17, No. 9. (September 2011), pp. 2842-2852,


Natural disturbances like wildfire, windthrow and insect outbreaks are critical drivers of composition, structure and functioning of forest ecosystems. They are strongly climate-sensitive, and are thus likely to be distinctly affected by climatic changes. Observations across Europe show that in recent decades, forest disturbance regimes have intensified markedly, resulting in a strong increase in damage from wind, bark beetles and wildfires. Climate change is frequently hypothesized as the main driving force behind this intensification, but changes in forest structure and composition ...


Human-caused climate change is now a key driver of forest fire activity in the western United States

Proceedings of the National Academy of Sciences (10 October 2016), 201612926,


[Excerpt] Effects of climate warming on natural and human systems are becoming increasingly visible across the globe. For example, the shattering of past yearly records for global high temperatures seems to be a near-annual event, with the five hottest years since 1880 all occurring since 2005. Not coincidentally, the single hottest year on record, 2015, also broke records for area burned by wildfire in the United States [...], eclipsing the previous high mark set just one decade prior. Scientists have known ...


Forest Service survey finds record 66 million dead trees in Southern Sierra Nevada

(June 2016)


[Excerpt] The U.S. Forest Service today announced that it has identified an additional 26 million trees dead in California since October 2015. These trees are located in six counties across 760,000 acres in the southern Sierra Nevada region of the state, and are in addition to the 40 million trees that died statewide from 2010 to October 2015, bringing the total to at least 66 million dead trees. Four consecutive years of severe drought in California, a dramatic rise in bark ...


Forest-landscape structure mediates effects of a spruce bark beetle (Dendroctonus rufipennis) outbreak on subsequent likelihood of burning in Alaskan boreal forest

Forest Ecology and Management, Vol. 369 (June 2016), pp. 38-46,


[Highlights] [::] We measured forest-landscape structure effects on disturbance patterns in Alaska. [::] Disturbance patterns and interactions were related to tree-species composition. [::] Bark beetles lead to increased probability of fire in mixed-spruce stands. [::] Results can inform management of disturbance in Alaska with climate change. [Abstract] Characterizing how variation in forest landscape structure shapes patterns of natural disturbances and mediates interactions between multiple disturbances is critical for anticipating ecological consequences of climate change in high-latitude forest ecosystems. During the 1990s, a massive spruce bark beetle (Dendroctonus ...


Characteristics of Norway spruce trees (Picea abies) surviving a spruce bark beetle (Ips typographus L.) outbreak

Trees - Structure and Function In Trees, Vol. 25, No. 6. (24 May 2011), pp. 965-973,


The characteristics of spruce individuals, which survived a massive bark beetle outbreak, were compared with the characteristics of neighbouring attacked trees in Šumava National Park (Czech Republic). Selected parameters related to crown geometry, stand conditions and distances between trees were measured or estimated. Significant differences were found between the surviving trees and the neighbouring trees attacked by I. typographus. Trees with a higher level of stem shading (longer crown length) tended to survive. The attacked trees were usually located in areas ...


Fine-scale spruce mortality dynamics driven by bark beetle disturbance in Babia Góra National Park, Poland

European Journal of Forest Research, Vol. 135, No. 3. (2016), pp. 507-517,


Bark beetle outbreaks have had major impacts on Norway spruce forests in Europe. The large majority of these forests are located in areas under forest management; thus, few studies have investigated outbreak-driven spruce mortality patterns unaffected by humans. Our study examined spruce mortality resultant from a beetle outbreak in a high-elevation, unmanaged forest over a 17-year span. We analyzed three tree-level survivorship and DBH datasets collected during pre-, mid-, and post-outbreak conditions to evaluate long-term mortality dynamics. We measured changes in ...


Tree and stand-level patterns and predictors of Norway spruce mortality caused by bark beetle infestation in the Tatra Mountains

Forest Ecology and Management, Vol. 354 (October 2015), pp. 261-271,


This study investigates temporal shifts in Norway spruce (Picea abies) mortality, stand structure characteristics, and stand complexity facilitated by a bark beetle (Ips typographus) outbreak that affected an unmanaged subalpine forest region in Tatra National Park, Poland in the late 2000s. Changes in survivorship and stand structure characteristics (diameter (DBH), basal area, height, age, and crown length ratio) of nearly 2500 spatially-referenced trees located in 64 long-term survey plots were compared over four time periods that spanned the duration of the ...


On underestimation of global vulnerability to tree mortality and forest die-off from hotter drought in the Anthropocene

Ecosphere, Vol. 6, No. 8. (August 2015), art129,


Patterns, mechanisms, projections, and consequences of tree mortality and associated broad-scale forest die-off due to drought accompanied by warmer temperatures—“hotter drought”, an emerging characteristic of the Anthropocene—are the focus of rapidly expanding literature. Despite recent observational, experimental, and modeling studies suggesting increased vulnerability of trees to hotter drought and associated pests and pathogens, substantial debate remains among research, management and policy-making communities regarding future tree mortality risks. We summarize key mortality-relevant findings, differentiating between those implying lesser versus greater levels of ...

Cross-scale Drivers of Natural Disturbances Prone to Anthropogenic Amplification: The Dynamics of Bark Beetle Eruptions

BioScience, Vol. 58, No. 6. (01 June 2008), pp. 501-517,


Biome-scale disturbances by eruptive herbivores provide valuable insights into species interactions, ecosystem function, and impacts of global change. We present a conceptual framework using one system as a model, emphasizing interactions across levels of biological hierarchy and spatiotemporal scales. Bark beetles are major natural disturbance agents in western North American forests. However, recent bark beetle population eruptions have exceeded the frequencies, impacts, and ranges documented during the previous 125 years. Extensive host abundance and susceptibility, concentrated beetle density, favorable weather, optimal ...


Anatomical and chemical defenses of conifer bark against bark beetles and other pests

New Phytologist, Vol. 167, No. 2. (03 May 2005), pp. 353-376,


[Summary] Conifers are long-lived organisms, and part of their success is due to their potent defense mechanisms. This review focuses on bark defenses, a front line against organisms trying to reach the nutrient-rich phloem. A major breach of the bark can lead to tree death, as evidenced by the millions of trees killed every year by specialized bark-invading insects. Different defense strategies have arisen in conifer lineages, but the general strategy is one of overlapping constitutive mechanical and chemical defenses overlaid ...


Individual vulnerability factors of Silver fir (Abies alba Mill.) to parasitism by two contrasting biotic agents: mistletoe (Viscum album L. ssp. abietis) and bark beetles (Coleoptera: Curculionidae: Scolytinae) during a decline process

Annals of Forest Science In Annals of Forest Science, Vol. 71, No. 6. (2014), pp. 659-673,


[Context] In recent decades, there have been increasing reports of forest decline, especially in Mediterranean forest ecosystems. Decline in tree vitality is usually due to complex interactions between abiotic factors and biotic agents that attack weakened trees. [Aims and methods] Estimating dendrometrical characteristics [basal area increment (BAI), age at DBH from tree ring counting, social status, height, and diameter], tree health status, and a competition index, we investigated the individual vulnerability of a French declining silver fir forest to both mistletoe (Viscum album L. ...


Spatiotemporal patterns of observed bark beetle-caused tree mortality in British Columbia and the western United States

Ecological Applications, Vol. 22, No. 7. (October 2012), pp. 1876-1891,


Outbreaks of aggressive bark beetle species cause widespread tree mortality, affecting timber production, wildlife habitat, wildfire, forest composition and structure, biogeochemical cycling, and biogeophysical processes. As a result, agencies responsible for forest management in the United States and British Columbia conduct aerial surveys to map these forest disturbances. Here we combined aerial surveys from British Columbia (2001–2010) and the western conterminous United States (1997–2010), produced 1-km2 grids of the area of crown mortality from bark beetle attack, and analyzed spatial and ...

Temperature as a potent driver of regional forest drought stress and tree mortality

Nature Climate Change, Vol. 3, No. 3. (30 September 2012), pp. 292-297,


As the climate changes, drought may reduce tree productivity and survival across many forest ecosystems; however, the relative influence of specific climate parameters on forest decline is poorly understood. We derive a forest drought-stress index (FDSI) for the southwestern United States using a comprehensive tree-ring data set representing AD 1000–2007. The FDSI is approximately equally influenced by the warm-season vapour-pressure deficit (largely controlled by temperature) and cold-season precipitation, together explaining 82% of the FDSI variability. Correspondence between the FDSI and measures ...
