Luminescent signals can be used by animals for a number of purposes, including courtship and defense, sometimes by the same individual. However, the relative costs of producing these different behaviors are largely unknown. In the marine ostracod Photeros annecohenae, males utilize extracellular luminescence for complex courtship displays, and both males and females luminesce as a predation def...

Patchy occurrences of benthic drift algae (i.e. loose lying macroalgal mats) may increase habitat complexity on normally bare soft bottoms, but at the same time, extensive amounts of drifting algal mats are known to stress the benthic fauna. This paper presents results of the first detailed study of the fauna associated with drift algal mats in the northern Baltic Sea. In order to assess the im...

The present study concerns seasonal variations, correlation coefficient and biodiversity indices of zooplanktons during January-December, 2008 in the Harsool-Savangi dam, Aurangabad, India. A total of 25 genera were recorded of which 10 were Rotifers, 8 Cladocerons, 5 Copepods and 2 Ostracods. Present study revealed maximum percentage wise compositions of Rotifers at north site were 58.28%, Cla...

a fauna of 16 species and genera of marine ostracoda is described and illustrated for the first timefrom the mid-cretaceous of the badamouyeh mountain in kerman province. the ostracod assemblagesuggests a favorable condition during the deposition of the strata. the ostracods can also be used for thecorrelation of cenomanian age formations in many places in the middle east
