In dryland regions, increased demand for water has led to the reduction of natural aquatic habitats and threatens persisting aquatic habitats. In the Madrean Sky Islands (MSI), water demands have also resulted in the creation of novel aquatic habitats, including stock ponds. Stock ponds are important surrogate habitat for native species, yet little is known about the aquatic invertebrates utili...

We evaluate the substantial amount of information accumulated on bacterial diversity in a variety of environments and address several fundamental questions, focusing on aquatic systems but including other environments to provide a broader context. Bacterial diversity data were extracted from 225 16S rDNA libraries described in published reports, representing a variety of aquatic and non-aquatic...

We report the first occurrence of congenital scoliosis in an early Permian aquatic parareptile, Stereosternum tumidum from Paraná state, Brazil. The spine malformation is caused by a congenital hemivertebra. These observations give insight into the biomechanical aspects of underwater locomotion in an axial skeleton-compromised aquatic amniote. This is the oldest record of a hemivertebra in an a...

The systematic analysis of the health of aquatic organisms may provide an important indicator for the evaluation of the water quality of natural aquatic environments. Inadequate water quality may provoke a wide range of problems in aquatic organisms, including genetic mutations, infectious diseases, behavioral modifications, physical dysfunction (including reproduction) and deformations or dysp...

purpose: the aim of this study is to change one of the primary impairments associated with multiple sclerosis, i.e. ataxia, in which there is insufficient postural control. materials and methods: the current randomized controlled trial investigated the effects of aquatic exercise on postural control in ms ataxic patients. thirty-two patients with multiple sclerosis with a degree of ataxia indic...

Aquatic weeds pose several problems in India. The canals of Chambal commanded area in Rajasthan and Madhya Pradesh and Bhakra-Nagal in Himachal Pradesh and Punjab have been greatly slowed by the aquatic weeds. Several irrigation and hydroelectric projects in the country like Tungabhadra project in Karnataka, Nagarjuna Sagar project in Andhra Pradesh and Kakki and Idikki reservoirs in Kerala are...

Aquatic reed is an important indicator for the ecological assessment of freshwater lakes. Monitoring is essential to document its expansion or deterioration and decline. The applicability of Green-LiDAR data for the status assessment of aquatic reed beds of Bavarian freshwater lakes was investigated. The study focused on mapping diagnostic structural parameters of aquatic reed beds by exploring...

The importance of the surrounding landscape to aquatic ecosystems has been well established. Most research linking aquatic ecosystems to landscapes has focused on the one-way effect of land on water. However, to understand fully the complex interactions between aquatic and terrestrial ecosystems, aquatic ecosystems must be seen not only as receptors of human modification of the landscape, but a...
