In total 20 species of aquatic insects have been recorded from a weed infested pond. Odonata was numerically the most abundant group constituting of 54% of the total aquatic insects even though these belonged to three species. Coleoptera though constituted only 22% of aquatic insects had 10 species. Urothemis signata and Ranatra filliformes were eudominant and dominant species respectively. Hyd...

We describe a commercially-available funnel trap for sampling aquatic vertebrates. The traps can be used in heavily vegetated wetlands and can be set in water up to 60 cm deep without concern for drowning the animals. They were especially useful for capturing the aquatic salamanders Siren lacertina and Amphiuma means, which have been difficult to capture with traditional sampling methods. They ...

Detection of Salmonella in pet turtles has been the focus of extensive research, but its incidence in free living turtles is not well known. The aim of this study was to evaluate the incidence of Salmonella in terrestrial and aquatic species of chelonians inhabiting a National Park in southwestern Spain. Individuals of the terrestrial tortoise Testudo graeca (n = 16) and the aquatic turtles Emy...

There is no published report regarding Iran's aquatic hyphomycetes. In an attempt to identify species of aquatic hyphomycetes in a river in central Iran (Zayande-Roud River), conidial frequency and distribution were determined by filtration. Water samples were collected monthly from two stations 55 km apart and filtered through millipore filters (5 um pore sizes). This was carried out for seven...

Heavy metals that enter marine environment and remain in the water as well as the sediments are accumulated by aquatic organisms, thus becoming highly good indicators to monitor metal accumulation in the long run. Metals are potentially harmful to humans and most organisms at varied levels of exposure and absorption. Northern East Mediterranean Sea is a crucial region as it is an area, shared b...

Evolutionary transitions between aquatic and terrestrial environments are common in vertebrate evolution. These transitions require major changes in most physiological functions, including feeding. Emydid turtles are ancestrally aquatic, with most species naturally feeding only in water, but some terrestrial species can modulate their feeding behavior appropriately for both media. In addition, ...

An investigation on the aquatic insect community of 10 selected sites of Deepor beel, the only Ramsar site of Assam situated on the southern side of River Brahmaputra was carried out during the month of March to November, 2013. During the study period aquatic insect community was represented by 31 species belonging to 18 families of 5 orders. Record of 17 species and 8 families of the order Hem...

This study determined the relative sensitivity of five species of aquatic macrophytes and six species of algae to four commonly used herbicides (atrazine, metribuzin, alachlor, and metolachlor). Toxicity tests consisted of 96-h (duckweed and algae) or 14-d (submerged macrophytes) static exposures. The triazine herbicides (atrazine and metribuzin) were significantly more toxic to aquatic plants ...

Trait-based approaches are widely used in community ecology and invasion biology to unravel underlying mechanisms of vegetation dynamics. Although fundamental trade-offs between specific traits and invasibility are well described among terrestrial plants, little is known about their role and function in aquatic plant species. In this study, we examine the functional differences of aquatic alien...
