When Similar Individuals Don't Attract: Absence of Assortative Mating by Coloration in a Damselfly With Honest Signaling

Ethology, EarlyView.
In Acanthagrion lancea damselflies, both sexes display blue ornamentation, but do they choose mates based on it? We tested whether mutual mate choice and time constraints influence ornament evolution. Blue coloration correlated with individual quality, but individuals did not choose mates based on color, and this was unaffected by time constraints over

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 ...

A framework and case study to systematically identify long‐term insect abundance and diversity datasets

Conservation Science and Practice, 2022
Biodiversity is in crisis, and insects are no exception. To understand insect population and community trends globally, it is necessary to identify and synthesize diverse datasets representing different taxa, regions, and habitats.

Water availability and land‐use shape the diversity of Odonata in the Middle East

Insect Conservation and Diversity, EarlyView.
Odonata diversity in the Middle East depends on the availability of long‐lasting waters, emphasizing the importance of preserving stable aquatic habitats for biodiversity conservation under climate change‐driven droughts. Agricultural expansion is associated with increased Odonata species richness, but overall trait diversity remains limited ...

The Odonate fauna (Insecta: Odonata) of Belihuloya, southern intermediate zone of Sri Lanka: A preliminary assessment and conservation implications

Journal of Asia-Pacific Biodiversity, 2022
Belihuloya situated in a biogeographical transition zone in south-central Sri Lanka is being threatened by land-use changes. Establishing baseline biodiversity knowledge of an indicator taxon within this lesser explored area, the present study ...

Conservation implications of shifting habitat use in migrating insects: Selection patterns in a threatened damselfly show that season‐specific actions are needed

Insect Conservation and Diversity, EarlyView.
Well‐preserved heathlands of NW Italy are the main overwintering habitat of Sympecma paedisca, while grassy margins in farmland are used only in summer and are avoided from autumn onwards. Grassy margins in farmland act as corridors during the species' migrations between its breeding (ricefields) and overwintering (lowland heathlands) grounds ...

Evolution of Crematogaster sordidula (Hymenoptera, Formicidae) Ants in the Mediterranean Region During Plio‐Pleistocene Climatic Changes

Zoologica Scripta, EarlyView.
ABSTRACT Understanding insect responses to global climate change involves identifying strategies used during past climate oscillations. Phylogeography offers a powerful framework to unravel how historical climatic and geological events have shaped the spatial genetic patterns of species, providing critical insights into evolutionary processes, whereas ...

Molecular bases of insect odorant receptor function: specificity and evolution

Biological Reviews, Volume 101, Issue 2, Page 1036-1049, April 2026.
ABSTRACT Insect odorant receptors (ORs) are a class of chemoreceptors that insects use to detect volatile cues in their environment. In recent years, major advances in the field of structural biology have made it possible to obtain the first structures of insect ORs.

A century of theories of balancing selection

Biological Reviews, Volume 101, Issue 2, Page 804-825, April 2026.
ABSTRACT Traits that affect organismal fitness are often highly genetically variable. This genetic variation is vital for populations to adapt to their environments, but it is also surprising given that nature – after all – ‘selects’ the best genotypes at the expense of those that fall short.
