La conservación de las especies polinizadoras es de gran interés para la humanidad. Además de ayudar en el mantenimiento del ensamblaje de los ecosistemas, los polinizadores permiten la producción de más de 75% de los cultivos alimenticios. En las últimas décadas se ha documentado la disminución en la diversidad y abundancia de especies polinizador...

In terms of conservation, Argentinian odonates have not been assessed using a quantitative approach. One way to achieve this is by modelling their distribution to gather the extent of occurrence. Thus, we modelled the current and future (projected year, 2050) potential distribution of 44 odonate species that occur in Argentina as well as in neighbo...
Article
Morphological variation is widespread, and one case is that of female morphs in damselfly insects. Current knowledge indicates that these female morphs are maintained by a fitness balance whereby male-like, clear-colored females (i.e. andromorphs) are more likely to “escape” from male harassment given their male mimicking compared to dark females (...

The Asian giant hornet (AGH, Vespa mandarinia ) is the world’s largest hornet, occurring naturally in the Indomalayan region, where it is a voracious predator of pollinating insects including honey bees. In September 2019, a nest of Asian giant hornets was detected outside of Vancouver, British Columbia; multiple individuals were detected in Britis...

Background: Theory predicts that parasites can affect and thus drive their hosts' niche. Testing this prediction is key, especially for vector-borne diseases including Chagas disease. Here, we examined the niche use of seven triatomine species that occur in Mexico, based on whether they are infected or not with Trypanosoma cruzi, the vectors and c...
Article
• Climate change is a key stressor for species. Two major consequences of climate‐induced range shifts are the formation of new areas of geographic overlap (i.e. sympatry) and an increased probability of hybridisation in the de novo created contact zones. • One method to effectively quantify the potential of hybridisation is to integrate ecological...

Damselflies and dragonflies (Insecta: Odonata) are currently facing a number of threats. One tool to provide a straightforward assessment of risk is distribution area. Here we have used ecological niche modeling to estimate distribution range for 6 species of Argia damselflies distributed in North America: A. cuprea, A. funcki, A. garrisoni, A. har...
Article

Local adaptation is of fundamental interest to evolutionary biologists. Traditionally, local adaptation has been studied using reciprocal transplant experiments to quantify fitness differences between residents and immigrants in pairwise transplants between study populations. Previous studies have detected local adaptation in some cases, but others...
Article
While gene flow can reduce the potential for local adaptation, hybridization may conversely provide genetic variation that increases the potential for local adaptation. Hybridization may also affect adaptation through altering sexual dimorphism and sexual conflict, but this remains largely unstudied. Here, we discuss how hybridization may affect se...

Article
Isolation barriers work at different instances during the mating process in odonate insects. In territorial damselflies, heterospecific interactions are mainly precluded by sexual (visual) isolation, while in non-territorial damselflies, heterospecific interactions are mostly precluded by mechanical isolation and sexual (tactile) isolation. In this...

Odonates have been frequently labeled as a taxa where males control female’s mating and fertilization decisions. Contrary to this position, in our contribution, we review instances where females can actually show choice of mates. Previous to mating, possible selected male traits are wing pigmentation, ability to defend oviposition sites , body colo...

Male abdominal grasping apparatus that are used to secure a female prior, during and after mating, are widespread in arthropods. The scarce evidence regarding its selective regime suggests that they are male adaptations to circumvent female mating decisions, as predicted by the sexual conflict hypothesis. A recent discussion regarding this way of s...

Recent studies have found that insect genitalic traits show negative allometry, i.e., are relatively small in relation to body size. One interpretation of this is that males use their genitalia to stimulate females. Thus, given the nature of damselfly copulation in which males physically reach the rival sperm that females have stored from previous...
Article
Ornaments may show hyperallometry in certain taxa, i.e. large individuals have proportionally larger ornaments than small ones. One hypothesis suggests that higher sexual selection intensity leads to steeper hyperallometric patterns.This study tested whether an ornamental trait subject to both intra- and intersexual selection showed steeper allomet...
Article
It is widely admitted that sexual selection is the responsible force behind genital traits. However, the particular mechanisms of genital evolution are still debated. Recently, studies of genital static allometry in insects have been used to elucidate such mechanisms. Insect genital traits are often reported to show negative allometry (i.e., a slop...

We are mapping the distribution, areas and potential threats of Mexican odonates. The idea is to obtain more accurate information of the conservation status of these animals. Also, we are producing books and handbook material for kids so that these can get to know these fantastic animals.
