Habitat Dependent Variations in The Rate of Oxygen Consumption, Rate of Ammonia Excretion and O: N Ratio of Freshwater Bivalve, Lamellidens marginalis From Lotic and Lentic Water of Godavari River at Paithan, During Summer

Considering the site (habitat) specific variations in the metabolic activities in the freshwater bivalves, we reported here the changes in the rate of oxygen consumption, rate of ammonia excretion and O: N ratio in the freshwater bivalve mollusc, Lamellidens marginalis (Lamark) from lotic and lentic water habitats on April-May during summer season. The adult freshwater bivalves, Lamellidens mar...

Freshwater mussel assemblage structure in a regulated river in the Lower Mississippi River Alluvial Basin, USA

1. This paper documents a diverse, reproducing freshwater mussel community (20 species) in Lower Lake } an impounded, regulated portion of the Little Tallahatchie River below Sardis Dam in Panola Co., Mississippi, USA. 2. Despite being regulated and impounded, the lake has a heterogeneous array of habitats that differ markedly in mussel community attributes. Four distinct habitat types were ide...

Fish diversity along spatial gradients in the Itaipu Reservoir, Paraná, Brazil.

Local and turnover patterns of fish diversity in the Itaipu Reservoir were evaluated and related to a longitudinal or river-dam gradient (composed of riverine, transitional, and lacustrine zones) and to transversal or upstream-downstream gradients of the tributaries (composed of lotic and lentic stretches of tributaries and reservoir shores). Thirteen stations were sampled quarterly during 2 ye...

Habitat stability affects dispersal and the ability to track climate change.

Habitat persistence should influence dispersal ability, selecting for stronger dispersal in habitats of lower temporal stability. As standing (lentic) freshwater habitats are on average less persistent over time than running (lotic) habitats, lentic species should show higher dispersal abilities than lotic species. Assuming that climate is an important determinant of species distributions, we h...

Fish assemblage structure of the Ipanema River, a small lotic environment partially protected by a Conservation Unit in southeastern Brazil.

A study on the fish assemblage of the Ipanema River, a small affluent of the Tietê River basin in southeastern Brazil, was performed aiming to look for structural patterns of species diversity in small lowland lotic environments. Fish samplings were performed every two months from June 2003 to April 2004 at four sample sites located on the lower stretch of the river. Local assemblage showed to ...
