“…This might also have practical implications for pest control since in contrast to the often predicted increased probability of pest outbreaks with higher daily mean temperatures in the future (Taylor et al. ), pest species might be detrimentally affected by night time warming (Zhao et al. ).…”

“…Further, diurnal temperature variations have been shown to affect insect ecology and behavior (Vangansbeke et al 2015, Speights et al 2017. This might also have practical implications for pest control since in contrast to the often predicted increased probability of pest outbreaks with higher daily mean temperatures in the future (Taylor et al 2018), pest species might be detrimentally affected by night time warming (Zhao et al 2014). This is complicated by potentially strong effects of daily temperature variations on trophic interactions between insect populations (Stoks et al 2017) and the resulting top-down effects on vegetation (Barton and Schmitz 2018).…”

Investigating the consequences of climate change under different land‐use regimes: a novel experimental infrastructure

Climate change and land‐use change are considered as the most important threats to ecosystems. Both factors can be expected to have interacting influences on ecosystem functions directly and indirectly via changes in biodiversity. Knowledge about these interactions is limited due to a lack of experiments which investigate climate change effects under different land‐use scenarios. Among the processes involved in ecosystem responses to global change, in particular, those occurring in soils or related to biotic interactions and microevolution were underinvestigated in previous experiments. Examinations of these relationships require spatial and temporal scales which go beyond those realized in the majority of ecological field experiments. We introduce a new research facility, the Global Change Experimental Facility (GCEF), which was designed to investigate the consequences of a future climate scenario for ecosystem functioning in different land‐use types on large field plots (400 m2). Climate manipulation is based on projections for the period of 2070–2100 with an increased temperature and a changed precipitation pattern consisting of reduced precipitation in summer and increased precipitation in spring and autumn. We subject five different land‐use types (two farming systems, three grasslands), differing in land‐use intensity, to ambient and future climatic conditions. The use of automated roofs and side panels to passively increase night temperatures results in an average increase in daily mean temperature by 0.55°C accompanied by a stronger increase in minimum temperatures (up to 1.14°C in average) with longer frost‐free periods and an increase in growing degree days by 5.2%. The combined use of mobile roofs and irrigation systems allows the reduction (in summer by ~20%) and increase in rainfall (in spring and autumn by ~10%) according to future scenarios superimposed on the ambient variation in precipitation. The large plot size and the technical configuration allow the establishment of realistic land‐use scenarios and long‐term observations of responses of ecosystem functions and community dynamics on relevant temporal and spatial scales. Thus, the GCEF provides a well‐suited platform for the interdisciplinary research on the consequences of climate change under different land‐use scenarios.

“…Research shows that velvetleaf is likely to decline in southern Indiana by the end of the century (McDonald et al 2009). Johnsongrass, a weed now causing significant issues in southern Indiana, is expected to migrate northward and become a growing problem across Indiana (Taylor et al, 2018). Other research suggests weed-crop competition will change.…”

“…A second essential consequence is the "fertilization" effect of rising CO 2 on plant photosynthesis; approximately 95% of plant species, those that rely solely on the C 3 photosynthetic pathway, could increase growth and reproduction as CO 2 increases, including agronomic and invasive weeds. There are hundreds of studies and several meta-analyses showing that both recent and projected increases in atmospheric CO 2 can have numerous physiological effects for a wide variety of C 3 plants [9][10][11][12].From a pest biology view, changes in regional and global climate, from temperature to DTR, to precipitation, are likely to affect the establishment, spread, and impact of pest species within managed systems [13][14][15][16]. For example, the continuous increase in CO 2 can directly stimulate the growth and fecundity of weedy species, but also has implications for qualitative changes for host plants, and for insects and plant pathogens [17].Biotic losses in managed systems, such as agriculture, can be substantial (more than 40% worldwide [2]).…”

Climate Change, Carbon Dioxide, and Pest Biology, Managing the Future: Coffee as a Case Study

The challenge of maintaining sufficient food, feed, fiber, and forests, for a projected end of century population of between 9-10 billion in the context of a climate averaging 2-4 • C warmer, is a global imperative. However, climate change is likely to alter the geographic ranges and impacts for a variety of insect pests, plant pathogens, and weeds, and the consequences for managed systems, particularly agriculture, remain uncertain. That uncertainty is related, in part, to whether pest management practices (e.g., biological, chemical, cultural, etc.) can adapt to climate/CO 2 induced changes in pest biology to minimize potential loss. The ongoing and projected changes in CO 2 , environment, managed plant systems, and pest interactions, necessitates an assessment of current management practices and, if warranted, development of viable alternative strategies to counter damage from invasive alien species and evolving native pest populations. We provide an overview of the interactions regarding pest biology and climate/CO 2 ; assess these interactions currently using coffee as a case study; identify the potential vulnerabilities regarding future pest impacts; and discuss possible adaptive strategies, including early detection and rapid response via EDDMapS (Early Detection & Distribution Mapping System), and integrated pest management (IPM), as adaptive means to improve monitoring pest movements and minimizing biotic losses while improving the efficacy of pest control.can encompass simple to sophisticated strategies (e.g., from hoeing to modifying the environment to utilize ecosystem services) to manage pest populations and ensuing damage.Recent and projected increases in atmospheric carbon dioxide (CO 2 ) concentration are expected to continue with a potential 2× increase over current CO 2 levels, and subsequent, concomitant increases in average temperature between 0.15 and 0.3 • C, per decade, by 2100 [3,4]. Such projections, as well as recent potential changes in extreme events, increase the degree of uncertainty of how these environmental changes could impact pest biology (insects, plant pathogens, weeds), and the consequences for future biotic losses from managed plant systems.Recent and projected increases in atmospheric CO 2 could change pest biology in two essential ways. The first is related to physical changes in the environment incurred as CO 2 increases. Such increases, along with other radiation trapping gases (e.g., CH 4 , N 2 O), will increase surface temperatures [5], cause changes in precipitation frequency [6], and alter the diurnal temperature range (DTR) [7], as well as the magnitude and distribution of extreme weather events [8]. A second essential consequence is the "fertilization" effect of rising CO 2 on plant photosynthesis; approximately 95% of plant species, those that rely solely on the C 3 photosynthetic pathway, could increase growth and reproduction as CO 2 increases, including agronomic and invasive weeds. There are hundreds of studies and several meta-analyses showing that both recen...
