“…Such accumulations occur there partly because the immediate, local population spreads from the sheltering vegetation but largely because the hedgerow acts as a windbreak and concentrates insects from passing airborne populations [44,89,90]. Accumulation increases with the impermeability of the windbreak [91]. Thus, the amount of small, airborne insects accumulated close to wooded hedgerows would be an interesting resource, especially for hawking bats that prey mainly on small flying insects, such as Diptera nematocera [61,92].…”

The role of hedgerows in maintaining biodiversity in areas of intensive agriculture is well known, particularly for bats. However, few studies have addressed the importance of the intrinsic characteristics of hedgerows for bats and disentangled the relative effects of local and landscape characteristics of hedgerows on bat activity. In an acoustic survey, we assessed bat activity by recording bat calls using detectors and manually verified all calls using spectrogram analysis. The parameters used to determine local hedgerow structures were the length of the line of trees, of shrub hedgerows, of wooded hedgerows without shrubs and of hedgerows including the three strata (tree, shrub and herb) at a local scale. We assessed the influence of hedgerow structure and on bat activity with an approach considering both species and community, comparing two different scales, the local and the landscape. We highlighted the importance of hedgerow characteristics for bats on both the local and landscape scales even though responses differ between species and spatial scales. We found that the presence of trees in hedgerows exerts a generally positive influence on bat activity and that hedgerows with the three strata had lower bat activity than hedgerows with trees. In our study, some bats seemed to prefer agricultural landscapes dominated by wooded hedgerows and, on the local scale, hedgerows that include trees with little diversified among strata, except for gleaning species. Our study shows that in terms of hedgerow management, conservation efforts must be designed and undertaken on both the local and landscape scales.

“…Trees L1, L2, L3 and L20 are surrounded by vegetation that may have perturbed wind flow, disrupting exposure to prevailing winds that would carry adult wasps and lead to gall wasp infestations. Vegetation, buildings, and other windbreaks do impact local insect movement (Hough 1951, Pasek 1988, and likely play a role in the patterns of gall wasp proliferation we observed.…”

© iForest -Biogeosciences and Forestry IntroductionExotic species invasions pose a substantial threat to biological integrity and sustainability. In our increasingly global economy, the rate of species' invasions is increasing exponentially, compromising biodiversity and altering ecosystem function. Non-native invasive species can affect plant, animal, and human health, and these invasions can have devastating economic impacts (Schnase et al. 2002). A critical challenge for invasive species management is gaining a complete understanding of the invasion process. Predicting the spatial and temporal dynamics of newly established invaders is crucial to understanding their proliferation and mitigating their impacts.Emerging technologies such as remote sensing improve our ability to better understand factors influencing an invasion, including the invasability of an area, the dynamics of an invasion, predictions about invasiveness (Schnase et al. 2002, Holcombe et al. 2007, and mitigation of these invasions. The combined use of Global Positioning Systems (GPS) and Geographic Information System (GIS) offers a powerful set of tools to record movement and describe the behavior of invasive organisms. In the last few decades GIS-based analyses have been used effectively to investigate the pattern of dispersal of many diverse organisms. Hyperspectral images, GPS collected data and GIS have been used to locate and map invasive plants in California (Underwood et al. 2003), and combined with spatial regression analysis, to identify the parameters affecting their spread (Dark 2004). Remotely sensed data and GIS have also been used to understand invasions by naturalized horticultural imports (Lemke et al. 2011) and woody plants (Rouget et al. 2004).To predict the impacts of the invasive hemlock woolly adelgid, Adelges tsugae Annand (Hemiptera: Adelgidae), in eastern North America, remote sensing and spatial analysis has been used to map the occurrence of the highly susceptible eastern hemlock, Tsuga canadensis (L.) Carr. (Clark et al. 2012). These technologies have also proven effective in modeling the spread of windborne and flying insects (Riley 1989, Reynolds & Riley 2002. Remote sensing and GIS have been used to locate bark beetle (Coleoptera: Curculionidae) populations, characterize the scope and magnitude of infestations, and predict their spread (Wulder et al. 2006). Similarly, gypsy moth, Lymantria dispar L. (Lepidoptera: Lymantriidae), distribution in North America has been described and predicted using GIS and spatial analysis (Liebhold et al. 1992). These technologies have also been used to monitor pests in cropping systems. Carriere et al. (2006) modeled the movement of the lygus bug, Lygus hesperus Knight (Heteroptera: Myridae), through diverse settings. They tracked lygus bug populations within different crops over time, and were able to distinguish between source and sink locations. Clearly GIS-based spatial analyses allow a greater understanding of the biology, behavior and ecology of insects and how they interact...

“…Agroforestry practices can reduce wind speeds, which increases pollinator efficiency and allows pollinators to forage during wind events that would normally reduce or prohibit foraging [42,91]. The protective effect on insect flight extends up to a distance equal to about nine times the height of the windbreak [97,98] and the sheltered zone contains higher numbers of pollinating insects [99], increasing pollination and fruit set [91,100].…”

Agroforestry can provide ecosystem services and benefits such as soil erosion control, microclimate modification for yield enhancement, economic diversification, livestock production and well-being, and water quality protection. Through increased structural and functional diversity in agricultural landscapes, agroforestry practices can also affect ecosystem services provided by insect pollinators. A literature review was conducted to synthesize information on how temperate agroforestry systems influence insect pollinators and their pollination services with particular focus on the role of trees and shrubs. Our review indicates that agroforestry practices can provide three overarching benefits for pollinators: (1) providing habitat including foraging resources and nesting or egg-laying sites, (2) enhancing site and landscape connectivity, and (3) mitigating pesticide exposure. In some cases, agroforestry practices may contribute to unintended consequences such as becoming a sink for pollinators, where they may have increased exposure to pesticide residue that can accumulate in agroforestry practices. Although there is some scientific evidence suggesting that agroforestry practices can enhance crop pollination and yield, more research needs to be conducted on a variety of crops to verify this ecosystem service. Through a more comprehensive understanding of the effects of agroforestry practices on pollinators and their key services, we can better design agroforestry systems to provide these benefits in addition to other desired ecosystem services.
