Species shifting their ranges under climate change are a conservation dilemma. Range-shifters may be threatened by in historic range. However, range-shifters likely to generalist opportunists, which could mean they harm aspects of biodiversity new ecosystems. Therefore, we need approaches rapidly assess how integrate into the community historically resident species. The small red-eyed damselfly...

The order Odonata (Insecta) is composed of aquatic insects popularly known as dragonflies and damselflies. Members this are closely linked to the conservation status their habitats; however, Wallacean shortfall in some regions still remains high. Volta Grande do Xingu region have high endemism groups, such Actinopterygii (fish), which can be applied other groups that not yet fauna at site, Odon...

En este trabajo se estudian dos especies de gonfidos (Odonata, Anisoptera) encontradas en los yacimientos calizas litograficas del Cretacico inferior España. Una estas especies, llerdaegomphus pallerolae (Gómez), es conocida Montsec (Provincia Lleida) y ahora redescribe; la segunda, torcae, una nueva especie encontrada el yacimiento Las Hoyas Cuenca). Ambas son estudiadas comparadas con resto a...

For nearly 80 years, the non-iridescent, blue, integumentary structural colours of dragonflies and damselflies (Odonata) have been attributed to incoherent Tyndall or Rayleigh scattering. We investigated the production of the integumentary structural colours of a damselfly--the familiar bluet, Enallagma civile (Coenagrionidae)--and a dragonfly--the common green darner, Anax junius (Aeshnidae)--...
