TLDR
Future research needs to consider insect herbivore phenotypic and genotypic flexibility, their responses to global change parameters operating in concert, and awareness that some patterns may only become apparent in the longer term.Abstract:
This review examines the direct effects of climate change on insect herbivores. Temperature is identified as the dominant abiotic factor directly affecting herbivorous insects. There is little evidence of any direct effects of CO2 or UVB. Direct impacts of precipitation have been largely neglected in current research on climate change. Temperature directly affects development, survival, range and abundance. Species with a large geographical range will tend to be less affected. The main effect of temperature in temperate regions is to influence winter survival; at more northerly latitudes, higher temperatures extend the summer season, increasing the available thermal budget for growth and reproduction. Photoperiod is the dominant cue for the seasonal synchrony of temperate insects, but their thermal requirements may differ at different times of year. Interactions between photoperiod and temperature determine phenology; the two factors do not necessarily operate in tandem. Insect herbivores show a number of distinct life-history strategies to exploit plants with different growth forms and strategies, which will be differentially affected by climate warming. There are still many challenges facing biologists in predicting and monitoring the impacts of climate change. Future research needs to consider insect herbivore phenotypic and genotypic flexibility, their responses to global change parameters operating in concert, and awareness that some patterns may only become apparent in the longer term.read more

The effect of elevated temperature on Barley yellow dwarf virus-PAV in wheat.

TL;DR: Plants grown at elevated temperature were significantly bigger and symptoms associated with BYDV-PAV were visible earlier than in plants grown at ambient temperature, which may have important implications for the epidemiology of yellow dwarf disease under future climates in Australia.

The effect of temperature on the development and life cycle regulation of the pine weevil Hylobius abietis and the potential impacts of climate change
TL;DR: The prepupal stage may serve to minimize the risk of overwintering mortality in the pupal stage and help to synchronize the life cycle, and the effects of climate change on development, voltinism and weevil mass are discussed.

Elevated air temperature alters an old‐field insect community in a multifactor climate change experiment
TL;DR: It is demonstrated that climatic warming may alter certain insect communities via effects on insect species most responsive to a higher temperature, contributing to a change in community structure.

Contributions of insects and droughts to growth decline of trembling aspen mixed boreal forest of western Canada.
Lei Chen,Jianguo Huang,Andria Dawson,Lihong Zhai,Kenneth J. Stadt,Philip G. Comeau,Caroline Whitehouse +6 more
TL;DR: The data suggest that insect outbreaks could be triggered by warmer early spring temperature instead of drought, implicating that potentially increased insect outbreaks are expected with continued warming springs, which may further exacerbate growth decline and death in North America aspen mixed forests.

Effects of climate change and management on timber yield in boreal forests, with economic implications : A case study
TL;DR: The economic assessment based on net present value (NPV) showed the need to adapt management in the future to utilise the increasing growth under the climate change and the greatest increase in timber yield was found when a thinning regime with high stocking over a hundred-year rotation was used.

Climate Change 1995: The Science of Climate Change
TL;DR: The most comprehensive and up-to-date assessment available for scientific understanding of human influences on the past present and future climate is "Climate Change 1995: The Science of Climate Change" as mentioned in this paper.
Book
The life forms of plants and statistical plant geography
TL;DR: The publication of a collected edition in English of the works of Professor Raunkiaer is a considerable event in the history of the science of vegetation; and Englishspeaking students of the subject all over the world have reason to be grateful to the Danish committee which conceived the plan and helped to finance the undertaking as discussed by the authors.

TL;DR: The authors showed that migratory species can respond rapidly to yearly climate variation, and further global warming is predicted to continue for the next 50-100 years, and some migratory animals can respond quickly to climate variation.
