Article
Females of the damselfly Ischnura graellsii display 3 color morphs, a male-like androchrome morph and 2 other morphs, infuscans and aurantiaca, which are not male-like. Previous research has suggested that male harassment has a negative effect on female fitness in many different insect species. Studying how male harassment affects fitness of the di...

Damselflies adapted to forest habitats are expected to be negatively affected by the disturbance of riparian forests, due to the change in insolation when trees are cleared. In this paper, we compare survivorship and behaviour of two populations of Heteragrion cooki by means of mark-recapture methods and focal observations of adults. We found simil...
Article
Colour-based traits are widespread in flying species due to the importance of visual perception in their communication. Ontogenetic colour changes and reversible physiological colours occur in some species and are used as communication signals to conspecifics. The genus Mnais (Zygoptera: Calopterygidae) shows both genetic colour polymorphism and ag...

Two key insights to better assess the ecological impact of global warming have been poorly investigated to date: global warming effects on the integrated life cycle and effects of heat waves. We tested the effect of a simulated mild (25 °C) and severe (30 °C) heat wave experienced during the larval stage on the flight ability of the damselfly Ischn...

Despite the great technological progress that has aided taxonomical identification, taxonomical issues remain for certain species found in remote and/or understudied geographical areas. The damselfly species Ischnura aurora has been the subject of a long-standing taxonomical debate, focused mainly on the existence of morphological and behavioural d...
Article
Population structure determines individuals’ interactions and trade-offs with evolutionary consequences. Male biased populations increase intrasexual competition and intersexual harassment, reducing female resource acquisition and thus, resources availability for the following generation. We analysed direct and cross-generational effects of male ha...
Article
The association of unrelated ant queens (pleometrosis) is supposed to improve nest foundation and competitiveness under environmental stress, but its evolutionary maintenance is difficult to explain because only one of the queens survives after nest foundation. My aim was to test the potential effect of queen association as a social buffer, i.e. as...

Ischnura praematura sp. nov. (Holotype ♂, China, Yunnan, Lijiang, 26º31´03.54"N, 100º13'38.89"E, 2396 m, 04 xii 2015, I. Sanmartín-Villar & H. Zhang leg.) is morphologically described, illustrated and compared with close species of the genus. Ischnura praematura can be mainly distinguished from its congeners I. aurora, I. rubilio and I. asiatica by...

The ‘functional allometry’ hypothesis proposes that the variation in allometric patterns of sexually selected traits is related to their function. We hypothesize that the allometric patterns for genitalia of aggressively territorial organisms are different from those in non-territorial organisms and predict that in aggressively territorial species,...

Early experience can prepare offspring to adapt their behaviors to the environment they are likely to encounter later in life. In several species of ants, colonies show ontogenic changes in the brood-to-worker ratio that are known to have an impact on worker morphology. However, little information is available on the influence of fluctuations in th...

1. The study of behavioural variability has a long research tradition in social insects. Because of their contribution to division of labour, between-individual variations have been mostly studied within the worker caste. In contrast, the level of behavioural variation between queens has been much less studied. 2. In ants, a high level of behaviour...

Can scientific laws be discussed on philosophical grounds? a reply to naïve arguments on 'predators' proposed by Bramble (2021). A recent paper by Bramble (2021) argues that given that predators inflict pain and fear on their prey we have the moral right to act to minimize these effects. The author proposes two alternatives. The first is to transfo...

A major challenge in evolutionary biology concerns how genetic and phenotypic variation is created and maintained. In this study, we investigated the origin(s) and evolutionary patterns of the female-limited colour polymorphism in Ischnura. This involves the presence of one to three colour morphs: one androchrome morph with coloration that resemble...
Chapter
Aquatic insects present diverse reproductive strategies, tactics, and complex life cycles which require distinct amounts of space and different food sources. And to achieve the reproductive goals they make use of many other strategies. Such reproductive repertoire allowed these insects to evolve the most intricate and fantastic mating systems, ofte...

We studied the demography and territorial behaviour of three species of the dam- selfly genus Hetaerina, H. aurora, H. caja and H. fuscoguttata, along three lowland streams in western Ecuador: Tabuga, Buenaventura and Moromoro. We measured recapture rates of marked individuals and estimated survival, longevity, sex ratio and population size of the...

Survival and longevity in neotropical damselflies (Odonata, Polythoridae). Longevity among insect orders varies greatly, and has mainly been studied in insects in temperate biomes, where seasonality determines high synchronization of reproductive activities and limits lifespan. Most forest damselflies in tropical regions have low population densiti...

Full-text available
Body colouration frequently possesses a communicative function, particularly in species with colour polymorphism and developed visual systems as odonates, and also affects the conspicuousness of animals in relation to the background. Therefore, these factors can influence colour evolution and its development. The ecology and ethology of Argia ocula...
Article
1. The evolutionary advantages that have driven the evolution of sex are still very much debated, and a number of benefits of parthenogenesis over sexual reproduction have been proposed. In particular, parthenogenetic individuals are thought to exhibit higher probabilities of establishment following arrival in new, isolated habitats such as islands...
Article
Full-text available
Current research on female colour polymorphism in Ischnura damselflies suggests that a balanced fitness trade-off between morphotypes contributes to the maintenance of polymorphism inside populations. The genetic inheritance system constitutes a key factor to understand morph fluctuation and fitness. Ischnura genei, an endemic species of some Medit...
Article
We studied Polythore damselflies by mark-recapture techniques in the Jatun Sacha Biological Reserve (Ecuador) for a period of 48 days in October-December 2014. Three species were found: Polythore mutata (MacLachlan) was the commonest species (111 individuals marked), Polythore derivata (MacLachlan) was rare (24 individuals) and Polythore concinna (...

We describe female colour morphs and ontogenetic colour changes of Ischnura rufostigma in three populations from China. Females showed two colour morphs, one androchrome, identical to males, and one gynochrome, with orange coloration when immature and green to brown thorax when mature. Population frequencies show that gynochrome females are the mos...

1.The pace-of-life syndrome (POLS) hypothesis integrates covariation of life-history traits along a fast-slow continuum and covariation of behavioural traits along a proactive-reactive personality continuum. Few studies have investigated these predicted life-history/personality associations among species and between sexes. Furthermore, whether and...

Amphibian reproductive modes are diverse and are characterised by complex adaptations, including vast variability in life history traits and different parental investment strategies. For instance, viviparity is rare in urodeles despite the potential ecological advantages gained in such populations by having semi-independency from water. The fire sa...

Question
The study of non-human animals with an anthropomorphic point of view generates errors because attributes and skills are used in individuals that do not have these properties. Nevertheless, when some term is detected in both (humans and non-humans), why should we employ different terms? It is not a loss in the holistic frame? I have in mind "personality" or "animal personality"; "behavior" or "animal behavior".
Question
Bold or shy behaviour can be modified with individual experience. Seems logical to think that bold individuals can be shyer learning about negative experiences and, in the other hand, shy individuals can be bolder with the lack of this events, but, how they are initially shy (excluding social effects)?
Question
What do you think about its genetic mechanism?
Some studies support that offspring has same/related behaviour than parents. How does the mechanism work?

Project
Inland waters, and in particular forest streams, are under great pressure due to high demands of water, pollution and degradation of riparian forests, which in many cases are replaced by plantations of fast-growing trees. This intensification of forestry determines direct effects on biodiversity, which are well known in temperate zones. In tropical forests, these effects have been less studied, particularly on organisms that, apparently, have no direct relationship with the forests. In this project we propose the use of the Odonata (in particular the damselflies or Zygoptera) as indicators of the loss of diversity in a new level, usually not considered, that we call "ethodiversity". The first objective is to determine how the intensive forestry practices affect communities of Odonata of tropical forest streams. Once the species most sensitive to the intensification of forest plantations are identified, we will conduct detailed studies of their behavior. We will descrive the ethological diversity of communities of primary forests and degraded areas. The project is proposed as a collaboration with scientists from different countries of the Neotropical region and Asia, contributing their experience and local knowledge. This will allow an optimal replication and will exploit the synergies between various groups of researchers. We want to determine which ethological characteristics are related to the risk of local extinction. Ultimately, the study will allow designing silvicultural practices that mitigate the effects of plantations, and contribute to a more ecological forestry. We will pay a special attention to species that have higher taxonomic uniqueness, and data and samples will be collected to resolve the taxonomic position of some of the lesser-known families of Odonata, thus combining basic and applied research.
