biodiversity in terra-firme forest streamlets in Central Amazonia: on the relative effects of neutral and niche drivers at small geographical extents.
Bionomic differences in odonates
and their influence on the efficiency of indicator species of environmental quality.
Additionally, it is unlikely that a reduction in dorsal spine number in resident freshwater threespine stickleback populations is related to Odonate
predation because Odanate naiad predators have not been detected in the Aleutians (D.
The aims of this study were to determine a correlation between water acidification and ion levels in the haemolymph and to examine the physiological response and ion change of the haemolymph of odonate
nymphs to acidic conditions in the laboratory.
The earlier emergence when in high densities may also be an evolutionary response to conspecific interactions as cannibalism, since odonate
larvae usually feed on conspecifics [13-16] or competition, since they can be aggressive towards conspecifics and even harm or kill neighboring larvae [1,16].

assemblage structure in relation to basin and aquatic habitat structure in Pantanal wetlands.
species may be good indicator species for the quality of aquatic habitats (e.g.
Over the years that site has produced interesting odonate
records including a swarm of Selysiothemis nigra, breeding Pseudagrion decorum (Feulner 2001) and breeding Anax imperator, as well as other unusual plant and animal records.
field guides are becoming common, and this book ranks among the best available.
Alternative prey influences efficacy of biocontrol agents, evident from the studies on cyclopoid copepod (26), dytiscid beetles (27,28), odonate
larvae (29), larvae of the predatory mosquito Toxorhynchites splendens (30), and heteropteran bugs (31-33).
But anyone who's fascinated by these often brightly colored, vaguely helicopter-like insects that flit through backyard gardens and hover around bodies of water will have plenty to learn and hundreds of colorful photos for identification of just about any odonate
that comes by.
