Historical changes in the phenology of British Odonata are related to climate [PDF]

open access: yes, 2007
Responses of biota to climate change take a number of forms including distributional shifts, behavioural changes and life history changes. This study examined an extensive set of biological records to investigate changes in the timing of life history ...

Field estimates of reproductive success in a model insect: behavioural surrogates are poor predictors of fitness [PDF]

open access: yes, 2011
Understanding, and therefore measuring, factors that determine fitness is a central problem in evolutionary biology. We studied a natural population of Coenagrion puella (Odonata: Zygoptera) over two entire breeding seasons, with over a thousand ...

Odonata: Who They Are and What They Have Done for Us Lately: Classification and Ecosystem Services of Dragonflies

open access: yesInsects, 2019
Odonata (dragonflies and damselflies) are well-known but often poorly understood insects. Their phylogeny and classification have proved difficult to understand but, through use of modern morphological and molecular techniques, is becoming better ...

Complete mitochondrial genomes of two damselfly species in coenagrionidae and phylogenetic implications

open access: yesMitochondrial DNA. Part B. Resources, 2021
Agriocnemis femina (Brauer, 1868) and Ischnura senegalensis (Rambur, 1842) are two damselflies inhabiting paddy lands. As an intermediate predator, they play an important role in controlling certain crop pest and mosquitoes.

Evolution determines how global warming and pesticide exposure will shape predator‐prey interactions with vector mosquitoes [PDF]

open access: yes, 2016
How evolution may mitigate the effects of global warming and pesticide exposure on predator–prey interactions is directly relevant for vector control.

Iflaviruses in arthropods: when small is mighty

open access: yesInsect Science, EarlyView.
Many arthropod species harbor iflaviruses, which often cause covert (asymptomatic) infections, but may still affect host fitness. We review the impact of iflaviruses on arthropod fitness, immunity, behaviour as well as the iflavirus’ host range, transmission, tissue tropism and the interactions with other microorganisms within arthropods.

Morph-Specific Fecundity and Egg Size in the Female-Dimorphic Damselfly Ischnura senegalensis [PDF]

open access: yes, 2010
Females of coenagrionid damselflies exhibit color dimorphism, consisting of an andromorph and a gynomorph. This study compared reproductive traits between the female morphs in both field-captured and laboratory-reared females of the female-dimorphic ...

Beyond Sexual Selection: Natural Selection Related Camouflage and Thermoregulation Shape Sexual Color Dimorphism in Diploderma Lizards

open access: yesIntegrative Zoology, EarlyView.
Integrating comparative spectrometry, image analysis, and thermal modeling, we reveal that (1) females optimize crypsis via background matching, (2) males prioritize high‐contrast disruptive patterning at a significant thermoregulatory cost (reduced solar heat gain), and (3) habitat‐specific monomorphism in Diploderma slowinskii underscores ecological ...

Structural Complexity of Artificial Habitat and the Feeding Success of Predatory Dragonfly and Damselfly [PDF]

open access: yes, 2013
The effect of different habitat complexity structure on the feeding success of predatoryDragonfly and Damselfly over the four of three hours trials was tested using an artificialhabitat complexity structure. Complexity of artificial habitat structure was

An experimental examination of dispersal decisions made by flight‐capable heteropteran insects in urban stormwater pond conditions

open access: yesEcological Entomology, EarlyView.
Salty conditions in urban stormwater ponds can influence dispersal timing in species‐specific ways for actively dispersing aquatic heteropteran insects. Assaying multiple aspects of dispersal propensity, Hesperocorixa obliqua emigrated earlier in stormwater pond conditions while overall probabilities remained unchanged; Notonecta undulata emigration ...
