The Odonata of Numidia, Northeaster Algeria Part II Seasonal ecology

This paper, a companion to Part I which treated status and distribution of Numidian Odonata, summarizes current knowledge of their seasonal ecology and identifies areas where promising research avenues exist. Annual patterns of adult occurrence and reproductive activity are used to infer life cycles, with particular reference to strategies that enable species to bridge the…

Ecology and distribution of Lindenia tetraphylla (Insecta, Odonata, Gomphidae): A review

Information (published and unpublished) on ecology, phenology, and geographical distribution of Lindenia tetraphylla is reviewed. It reaches from Sardinia (Italy; in the past also Spain) in the West, along the northern coasts of the Mediterranean, the Caspian region and the Middle East, to Kazakhstan, Kirgizia, Afghanistan, and Pakistan in the East. The southernmost record is…

Odonata Concordance amongst aquatic taxa in brazilian savanna streams

Environmental management is one of the most important activities in ecological conservation at present. Faced with various socioeconomic impacts (e.g., urbanization, agriculture, and logging), practical and effective ways to analyze and determine how biodiversity is affected by these anthropogenic activities are essential.

Environmental impacts from human activities affect the diversity of the Odonata (Insecta) in the Eastern Amazon

Land use influences the biodiversity of stream systems by changing the chemical composition of the water and the physical structure of the habitat. The present study evaluated the influence of these processes on the diversity metrics of Odonata at regional and local scales, testing the hypothesis that the two odonate suborders Anisoptera and Zygoptera will respond differently to habitat and landscape variables.
