Cladoceran communities of two lakes of Nevado de Toluca Volcano, Central Mexico, were studied. A new species of Aloninae, Alona manueli sp. nov., is described. It was previously confused with Palearctic Alona intermedia Sars, 1862, but clearly differs from it in the morphology of postabdomen, head shield and head pores, and thoracic limbs. Position of Alona manueli sp. nov. within the genus is ...

Lobesia botrana (Denis & Schiffermüller, 1775) (Lepidoptera: Tortricidae) is one of the most destructive pests of grape in the Palearctic region. The potential geographical distribution of this pest is important to agriculture security. In this study, Maxent and ArcGIS were used to project the potential geographical distribution of L. botrana in China under the current climate. The result indic...

Tephritis arnicae (Linnaeus, 1758) from Europe was the hitherto only Palearctic species of the genus Tephritis known to infest flowerheads of asteraceous plants of the tribe Senecioneae. An additional species with similar biology, Tephritis arsenii, new species, recently discovered in Iran and Armenia is described. It is very similar to T. arnicae in the shape of the aculeus and spermathecae, a...

Aim The need to forecast range shifts under future climate change has motivated an increasing interest in better understanding the role of biotic interactions driving diversity patterns. contribution shaping broad-scale species distributions is, however, still debated, partly due difficulty detecting their effects. We aim test whether spatial exclusion between potentially competing can be detec...

Abstract Biological invasions represent one of the main contemporary pressures facing freshwater ecosystems, and a better understanding invasive species potential distributions is essential to prepare for future stressors. Crustacean invaders contribute significantly global with Ponto-Caspian region being primary donor areas Palearctic. The amphipods Dikerogammarus villosus haemobaphes , popula...
