“…Similarly, for PO activity we found an upregulation in response to the heat wave which was stronger in northern larvae. This result contrasts with Janssens et al (2014) who reported a stronger decrease in PO activity in northern compared to southern I. elegans when exposed to a heat treatment in the adult stage. This also illustrates the importance of studying delayed interactions between stressors within the same life stage as well as across metamorphosis.…”

“…Future studies considering more biomarkers and especially those looking at chronic effects may therefore be rewarding. Janssens et al (2014) also observed a synergetic negative effect between larval CPF exposure and adult heat treatment in the study species but this time on adult PO activity. Synergistic delayed effects between stressors are of major concern for risk assessment (Segner, 2011), and our study together with the one by Janssens et al (2014) add to this topic by illustrating that the sequence stressors are imposed and whether or not they are separated by metamorphosis may determine the outcome.…”

“…We chose to study Ischnura elegans (odonata, Coenagrionidae) as this is a very common damselfly species in Europe showing a broad latitudinal range (Dijkstra, 2006) and its response to CPF has been well studied (e.g. Dinh Janssens et al, 2014). CPF, an organophosphate insecticide, is an important pesticide to study in this context as it is a priority pollutant in the European Water Framework Directive (2000/60/EC) which has been approved under the European plant protection products regulation (1107/2009).…”

“…A study looking at the life history of Coenagrion puella under pesticide stress suggested that the sensitivity of life-history traits depends on the type of pesticide and the exposure time, being increased development time the only life-history trait which showed consistency across pesticide treatments in the long-term exposure experiment (atrazine, carbaryl and endosulfan in this case) (Campero et al, 2007). On the other hand, exposure of Ischnura elegans larvae to a pesticide (chlorpyrifos) decreased immune function signifi cantly, and adult heat stress caused a stronger decrease in immune function, indicating that temperature and pesticide stress interact across metamorphosis (Janssens et al, 2014). Moreover, urban populations of C. puella larvae showed increased activity levels when exposed to chlorpyrifos at 20° and 24°C while showing decreased food intake under pesticide stress at 24°C, compared to rural populations which showed decreased activity and food intake in all treatments (Tüzün et al, 2015).…”

“…These studies allow the partitioning of genetic and environmental factors to investigate the relative contributions of plasticity and adaptation, and have suggested that local adaptation to temperature (Dinh Van et al, 2014;Arambourou & Stoks, 2015) and pesticide stress (Tüzün et al, 2015) is common in odonates. Hence, studying phenotypic variation in urban environments represents a great opportunity for researchers in ecology and evolution to observe the complex, underlying processes of how species adapt to new circumstances through the use of urban habitat patch networks as "natural experiments".…”

ISSN (online): 1802-8829http://www.eje.cz gate current research on the impacts of urbanisation using odonates as a model group. First, we will present a brief overview on the impacts of urbanisation on terrestrial and freshwater ecosystems, then we conduct a systematic literature review regarding odonates in urban environments and outline the plausible effects on odonates, followed by the use of odonates as bioindicators, the conservation value of urban wetlands for odonates, a summary of evolutionary strategies for species to cope with urban stressors, and fi nally we conclude by identifying research needs. THE EFFECTS OF URBAN STRESSORS ON TERRESTRIAL AND FRESHWATER ECOSYSTEMSThe wide range of impacts associated with urbanisation indicates that it exerts a considerable effect on terrestrial biodiversity. Most studies show that species richness and evenness is reduced in highly urbanised regions, depending on the taxonomic group observed, degree of urbanisation, and spatial scale of analysis (McKinney, 2002(McKinney, , 2008. For example, butterfl ies (Ruszczyk, 1987;Ruszczyk & De Araujo, 1992; Blair & Launer, 1997) and ground arthropods (McIntyre et al., 2001) show this tendency. The general pattern of biodiversity decrease in cities is probably due to the fact that over 80% of land in city cores is covered by buildings and pavements, with the remain- Abstract. The expansion of urban areas is one of the most signifi cant anthropogenic impacts on the natural landscape. Due to their sensitivity to stressors in both aquatic and terrestrial habitats, dragonfl ies and damselfl ies (the Odonata) may provide insights into the effects of urbanisation on biodiversity. However, while knowledge about the impacts of urbanisation on odonates is growing, there has not been a comprehensive review of this body of literature until now. This is the fi rst systematic literature review conducted to evaluate both the quantity and topics of research conducted on odonates in urban ecosystems. From this research, 79 peer-reviewed papers were identifi ed, the vast majority (89.87%) of which related to studies of changing patterns of biodiversity in urban odonate communities. From the papers regarding biodiversity changes, 31 were performed in an urban-rural gradient and 21 of these reported lower diversity towards built up city cores. Twelve of the cases of biodiversity loss were directly related to the concentrations of pollutants in the water. Other studies found higher concentrations of pollutants in odonates from built-up catchments and suggested that odonates such as Aeshna juncea and Platycnemis pennipes may be candidate indicators for particular contaminants. We conclude by identifying current research needs, which include the need for more studies regarding behavioural ecology and life-history traits in response to urbanisation, and a need to investigate the mechanisms behind diversity trends beyond pollution.

To fully comprehend and predict the impact of drivers of global change such as climate warming and pollution, integrated multi‐trait approaches are needed. As organismal traits are often correlated, responses to stressors are expected to induce coordinated changes in many traits. A promising framework to study this is the pace of life syndrome (POLS), which predicts the integration of life history, behavioral, and physiological traits along a fast‐slow continuum. Using an integrative multi‐trait approach, we evaluated the presence of a POLS both within and across latitudes and how POLS patterns are affected by warming and metal pollution. We studied this in Ischnura elegans damselfly larvae of replicated low‐ and high‐latitude populations that strongly differ in voltinism (three to four generations per year vs. one generation every two years) reared in a common‐garden experiment at two temperatures. Across latitudes, life history, behavior, and physiology covaried in accordance with the POLS, with the fast‐paced low‐latitude damselflies characterized by a fast growth rate, high activity, and more explorative and risk‐taking behavior, fast metabolic rate, and low investment in immune function (activity of phenoloxidase). This fast POLS strategy was associated with a higher sensitivity to metal exposure and a higher vulnerability to predation. Warming caused opposite responses between the latitudes consistent with differential thermal adaptation in growth rate, behavior, and oxidative stress parameters. Despite this, damselflies of both latitudes showed a consistent pattern in phenotypic correlations among traits that, moreover, was not affected by warming and metal exposure. Within latitudes, there was no full support for the POLS. More active larvae were more explorative and risk taking, which aligned with the fast‐slow life history axis, but less strong than at the across‐latitude level. Physiological traits were also integrated within latitudes, yet there was no unambiguous coupling with the fast‐slow life history continuum. The consistent syndrome structure, if underpinned by genetic correlations, may restrict the independent evolution of individual traits, yet may not necessarily constrain adaptive evolution of integrated trait sets. This is because the covariance pattern was to a large extent similar across latitudes and within latitudes, suggesting adaptive trait integration guiding adaptive evolution of trait sets along the fast‐slow continuum.
