The importance of tropical mountain forests for the conservation of dragonfly biodiversity: A case from the Colombian Western Andes

Forests have been widely recognized as key habitats for odonate (dragonflies and damselflies) biodiversity, but the importance of forests for holding odonate biodiversity remains understudied in tropical mountains, one of the most diverse ecosystems on the planet. Here we describe the odonate assemblage composition along the elevation gradient in the Tatamá Mountains (Colombian Cordillera Occidental).

Dragonfly (Odonata) community structure in the Eastern Highlands Biodiversity Hotspot of Zimbabwe: potential threats of land use changes on freshwater invertebrates

We examined the diversity and potential drivers of dragonfly distribution in a biodiversity hotspot of Southern Africa (Eastern Highlands, Zimbabwe) by surveying 30 sites (13 lentic and 17 lotic habitats) located within this region. Additionally, we identified the anthropogenic factors that may threaten Odonata diversity and abundance. Our results revealed that 27 odonate species are…

Odonata biodiversity of the Argentine Chaco biome

Odonates of small temporary pools, marshes, large permanent ponds, oxbow lakes, dams, and perennial rivers were sampled in the semiarid Chaco biome of NW Argentina between September 2007 and December 2008. Information from 35 localities yielded 60 species; presence/absence information of species was recorded in a spatial-relational database. Alpha, beta, and gamma diversity and total…

New records of Odonata (Insecta) for the extreme northwest of the Brazilian Amazon

Brazil hosts a wide range of Odonata species, including many hitherto unde¬scribed ones, especially in remote and unexplored regions where logistics are difficult. The northwestern Brazilian Amazon is an example of this situation, and many locations still need to be sampled there and have their taxonomic inventories compiled.
