Analysis of adult damselfly fecal material aids in the estimation of antibiotic-resistant Enterobacterales contamination of the local environment [PDF]

PeerJ, 2018
Because damselflies are ubiquitously but focally present in natural environments and play a critical role as predators of other insect species, the fecal matter of damselflies may be useful for investigating antibiotic-resistant bacterial populations ...

Odonata (Insecta) diversity of Chinnar Wildlife Sanctuary, the southern Western Ghats, India

Journal of Threatened Taxa, 2015
A study was conducted at Chinnar Wildlife Sanctuary, Idukki District, Kerala, the southern Western Ghats, to assess the diversity of odonates. We report 48 species of odonates, which include 31 species of Anisoptera (dragonflies) and 17 species of ...

Immune function and parasite resistance in male and polymorphic female Coenagrion puella

BMC Evolutionary Biology, 2006
Background Colour polymorphisms are widespread and one of the prime examples is the colour polymorphism in female coenagrionid damselflies: one female morph resembles the male colour (andromorph) while one, or more, female morphs are described as ...

Do egg parasitoids increase the tendency of Lestes sponsa (Odonata: Lestidae) to oviposit underwater?

European Journal of Entomology, 2015
The selection of oviposition sites by insects can significantly affect egg mortality. Spreadwing damselflies (Odonata: Lestidae) predominantly lay their eggs in parts of plants growing above the surface of water and only occasionally also those parts ...

Exploring interdisciplinary aspects for conservation management: The case of land hermit crab wildlife trade in Taiwan

People and Nature, EarlyView.
Abstract Most conservation policies and management primarily focus on vertebrate animals. However, considering the high demand for invertebrate species in the exotic pet markets, it is crucial to give them great consideration. This research explores Coenobita purpureus, a land hermit crab newly recorded in Taiwan in 2017.

Diversity of Palaearctic Dragonflies and Damselflies (Odonata)

Diversity, 2022
More than 1.2 million distribution records were used to create species distribution models for 402 Palaearctic species of dragonflies and damselflies. On the basis of these diversity maps of total, lentic and lotic diversity for the whole of the Palaearctic (excluding China and the Himalayan region) are presented.

Impacts of Habitat Management on Larvae of the Damselfly Coenagrion mercuriale (Coenagrionidae, Odonata)—A Laboratory Study

River Research and Applications, EarlyView.
ABSTRACT Habitat management of small lotic waterbodies is essential to maintain flow and the quality of the habitats. For this purpose, aquatic plants are typically removed by authorities. This is done in a more or less disruptive manner, depending on the risk of interference with the bed.

Compensatory growth and oxidative stress in a damselfly [PDF]

Proceedings of the Royal Society B: Biological Sciences, 2008
Physiological costs of compensatory growth are poorly understood, yet may be the key components in explaining why growth rates are typically submaximal. Here we tested the hypothesized direct costs of compensatory growth in terms of oxidative stress. We assessed oxidative stress in a study where we generated compensatory growth in body mass by exposing

Dragonflies and damselflies (Odonata) in urban ecosystems: A review

European Journal of Entomology, 2016
The expansion of urban areas is one of the most significant anthropogenic impacts on the natural landscape. Due to their sensitivity to stressors in both aquatic and terrestrial habitats, dragonflies and damselflies (the Odonata) may provide insights ...

Competition for food affects the strength of reproductive interference and its consequences for species coexistence

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Competition for food and reproductive interference (negative interspecific sexual interactions) have been identified as major drivers of species exclusion. Still, how these biotic interactions jointly determine competitive dominance remains largely unknown.
