“…Whether flight ability was also correlated with monarch body size was not discussed in the paper. Additionally, a 4 C increase in rearing temperature resulted in reduced flight muscle mass and flight endurance in the damselfly Ishnura elegans (Tüzün et al, 2018).…”

Most of our understanding of the effects of climate warming on insect body size comes from laboratory experiments. Whether these studies predict patterns in nature is largely unknown. Here we examine the relevance of laboratory warming experiments for wild populations of the butterfly Pieris rapae. We tested two predictions: (i) butterflies reared at warmer temperatures in the laboratory should attain smaller adult sizes and have reduced flight ability, and (ii) in nature, this trait combination should lead to smaller butterflies visiting fewer flowers and accumulating less pollen. Overall, we found that warm‐reared butterflies were indeed smaller and flew more slowly compared to colder‐reared conspecifics. Additionally, wild‐caught small butterflies carried fewer, and a lower diversity of pollen grains compared to larger butterflies. Our warming experiments thus largely predicted pollen collection patterns in wild P. rapae. This study demonstrates that increased temperatures will likely have important consequences for butterfly‐plant interactions in nature.

“…Additionally, wing area of fore‐ and hind‐wings was measured using photographs of live individuals in dorsal view with the software ImageJ (Schneider et al., 2012). Then, wing loading was calculated as the ratio of the body mass divided by the total wing area (Tüzün et al., 2018).…”

Habitat use and movements of a large dragonfly (Odonata: Anax imperator) in a pond network

Local movements of aquatic insects within the surroundings of waterbodies aim essentially to find food, mates, resting sites, or avoid predation. Distances moved are very variable among species and may also differ depending on sex or age at the intraspecific scale. Despite a large panel of studies on odonate activities near waterbodies, little is known about their movements and behaviour in the surrounding landscape matrix. This knowledge is, however, crucial to support management schemes of pond networks and allow improvement of connectivity between them. In this study, 87 individuals of the large dragonfly Anax imperator were identified with a unique code on the wings and monitored visually on five ponds during summers 2017 and 2018. Simultaneously, 54 individuals were equipped with radio transmitters and tracked for up to 15 days. We built Cormack Jolly Seber models to test which factors are important for movement and survival of individuals, and calculated home ranges. Additionally, we performed a step selection analysis on the telemetry data to identify the terrestrial habitats selected by A. imperator at the interface between a rural area and a suburban area in north‐western France. A reduction of the survival rate was observed on the day immediately following capture regardless of the marking method. Individuals equipped with radio transmitters had a lower estimated daily survival (0.78; 95% confidence interval = 0.70–0.85) compared to wing‐marked individuals (0.89; 95% confidence interval = 0.85–0.92). Wing loading and age were the main variables influencing dragonfly survival for both methods. The probability of movement between ponds was similar for both sexes, but radio‐tracking data showed that females moved significantly further away in the landscape matrix than males, with one female detected up to 1,902 m away from the release pond. Females also had a larger home range (mean 95% kernel: 50 ha) than males (mean 95% kernel: 5 ha). Reproductive behaviour of males and flying behaviour of females were positively related to air temperature. Individuals of both sexes were present on ponds more often than in all other habitats whatever their activity. High trees were the preferred place to rest when air temperatures were low, especially for females. Overall, this study highlights the importance of integrating neighbouring trees in management schemes of ponds. It also confirms that preservation of pond networks must include on several hectares of land around ponds to meet the aquatic and terrestrial needs of amphibious organisms such as odonates. Our radio‐tracking data provide a basis for further studies on the persistence of odonate meta‐populations in fragmented landscapes.

“…The costly nature of manipulating water temperature in semi-natural conditions and challenge of controlling treatments that follow the natural fluctuations of the ambient, environmental temperature are reasons for the rarity of these studies. These manipulations of thermal regimes are more achievable in smaller, closed mesocosm systems mimicking pond systems [80][81][82][83][84]. By contrast, achieving these in open stream mesocosm systems (e.g.…”

Purpose of Review Global warming and pollution are among the five major causes of global biodiversity loss, particularly in aquatic invertebrates which are highly diverse but understudied. In this review, we highlight advancements in current environmental studies investigating the interactive effects between warming and contaminants in freshwater and marine invertebrates. We not only focused on temperate regions but also synthesized information on the less studied Arctic/Antarctic and tropical regions. Recent Findings In general, the same combination of warming and contaminants may result in either additive or non-additive interactive effects depending on taxa, the response variable, life stage, genotype, exposure level, duration and order of exposure, and the number of exposed generations. For traditional contaminants such as metals and pesticides, combined effects with warming at the individual level were generally synergistic. Growing evidence suggests that multigenerational exposure can shift the interaction between warming and contaminants toward antagonism, while contemporary evolution may change the interaction type. Summary Our synthesis highlights the importance of temporal aspects in shaping interaction type, including order of exposure, ontogenetic effects, transgenerational effects, and evolution. The combination of laboratory experiments (to advance mechanistic understanding) and outdoor mesocosm studies or field observations (to increase realism) is needed to obtain comprehensive assessments of interactive effects of warming and pollutants from genes to ecosystems.
