As warm-adapted insects of tropical origin, Odonata cope with cold periods by seasonal
regulation and diapause. A model for larval-overwintering species is proposed with three …

In the Mediterranean, Urothemis edwardsii is one of the most threatened dragonfly species
with a relict population restricted to the northeast of Algeria. Despite the recent subtle local …

Understanding habitat requirements of species of conservation concern is central for their
conservation and management. Although much of the research attention has been focused …

Aquatic macro-invertebrates play a vital role in the food chain of river ecosystem at several
trophic guilds and consumer levels, and are used as biomonitoring tools for aquatic …

In natural communities, closely related species are phenotypically similar but usually
spatially and/or temporally isolated. In odonates, interspecific competition occurs not only at …

Emergence is a critical phase in the life cycle of odonates because then they are highly
susceptible to predation and damage. Thus the ecological understanding of this …

Urothemis edwardsii is one of the most threatened dragonfly species in the Mediterranean.
Recent investigations and conservation efforts have increased the local geographic …

Semi-aquatic insects contribute to critical ecological functioning of freshwater habitats in
both the aquatic and terrestrial phase of their life. Traditional methods of studying their …

Urban rivers are very important elements of the urban landscape, but increasingly degraded
by human activities. We studied the composition and emergence patterns of odonates in …

Environments with higher complexity harbor a greater biodiversity and can directly influence
on certain behaviors of aquatic animals. Here, we tested whether habitat complexity predicts …
