Abstract:

Patterns of epilithic algal and bacterial productivity were examined in a developing community on newly exposed stream bedrock for a period of 10 wk and in an undisturbed bedrock community used as a seasonal control. Physical and chemical changes were minimal over the experimental period. Bacterial colonization occurred initially and was rapidly followed by the development of a monolayer of adnate diatoms. Subsequent bacterial development coupled with maximum rates of bacterial productivity may have depended upon the algal cells for physical refugia, mucilage production, and/or other growth-pr

Abstract:

The subject of the paper is to study the effect of the different river habitat on biological diversity of microalgae in order to reveal the status of algae indicators in the evaluation of river ecosystem health. The study is conducted to compare planktonic algae and epilithic algae in Shendinghe rive (SR) and Qihe river (QR) of Danjiangkou reservoir in August 2010. The trophic status is evaluated by saprobic system. There are 193 species (varieties) belonging to 98 genera and 7 phylums of planktonic algae and 61 species (varieties) belonging to 36 genera and 3 phylums of epilithic algae in the

Abstract:

The influence of golf course operation and construction on benthic algal communities in headwater streams on the Precambrian Shield was investigated using a reference condition approach. Streams were sampled for water chemistry and epilithic benthic algae on operational golf courses, on courses under construction, and from nearby minimally impacted reference locations. Epilithic diatom community structure was different in reference streams than in operational golf course streams, the latter indicating nutrient enrichment, higher pH, and disturbance.

Abstract:

Aiming to resolve some of the problems regarding monitoring of heavy metals in rivers using Cladophora glomerata and epilithic algal communities, a year’s survey of Co, Cd, Cu, Fe, Mn, Pb and Zn has been conducted on the river Vardar, FY Republic of Macedonia. Obtained results and statistical analysis clearly point out the well documented possibility of using epilithon (basically diatom communities) as a monitoring tool, since correlation patterns for epilithon are either better or the same as those for Cladophora, while at the same time epilithon is much more reliable for monitoring, especial

Adherent epilithic microorganisms recovered from rocks submerged 10 to 20 cm in two different rivers were examined by electron microscopy and enumerated after dispersion in M-9 salts by viable plate counts.

This structured communal mode of growth was common among epilithic microbial communities of different rock types.

Abstract:

The percent cover and composition of benthic macroalgal growths and the structure of epilithic diatom communities were analyzed in 1995 at four sites in a stream flowing through a cultivated field near Kintore, Ontario, Canada. The dominant epilithic diatom taxa did not differ greatly among sites. However, a correspondence analysis of the diatoms sampled monthly between July and September separated an upstream site from those receiving agricultural runoff. Sites downstream of agricultural inputs showed an increase in the cover of Cladophora glomerata (L.) Kütz and other green algae, and in gen

Salvinia molesta D.S. Mitchell (Salviniaceae) is a damaging free-floating invasive alien macrophyte native to South America.

Development of epilithic algal communities was monitored in fast- (29 cm∙s−1) and slow-current (12 cm∙s−1) outdoor experimental stream channels for 33 d following a simulated spate.

Maximum algal abundances, which seemed to reach carrying capacity in both current environments, were lower in fast current than in slow. The percentage of live cells in diatom assemblages decreased during community development. The small, monoraphid diatom Achnanthes minutissima Kütz. dominated

Information concerning the drivers of seasonal variation in algal biomass in subtropical mountain streams is limited. To identify the drivers of biomass dynamics for epilithic algae, a 20-month study was conducted in mountain streams in Taiwan, an area characterised by different levels of riparian vegetation coverage and agricultural activity, in which a process-based model was optimally fit to field data. We found that episodic typhoon-induced floods were the major drivers shaping the seasonal variations in algal biomass. Flow-induced detachment was frequently observed in periods of higher al

Pingüinera Stream is one of the two main lotic environments of Cierva Point (Antarctic Specially Protected Area No. 134) on the Danco Coast, Antarctic Peninsula. It originates in a large snowfield, flows through a penguin rookery, moss and grass banks, discharging into Cierva Cove. During late Antarctic summer 2003, we sampled the stream at six locations along its course. Abiotic features characterize it as a clear water system, yet receiving a very high amount of PO4-P and NH4-N from the rookery. These nutrients decrease downstream mainly due to uptake by epilithic algae and oxidation of NH4+

A large number of stream-dwelling animals feed on epilithic algae and must scrape or brush off food that is firmly attached to rough stones. The mouthparts of these highly specialized alga grazers are equipped with brushes, rakes, gouges, excavators, and rasps. Because they scrub across the rough substratum, these different types of feeding apparatus all become extremely worn down after a short time. The delicate bristles of brushes, the prongs of rakes, and the fine structures of rasps abrade swiftly, and often completely disappear after having been used for removing epilithic algae from ston

Factors controlling the preference of P. vulgata for epilithic biofilm or adult algae are still not clearly established. Here, we test the h

The largest proportion were epilithic (50%), followed by epiphytes on H. wrightii (38.4%), epipsammics (8%), and epiphytes on other algae (4%). Epiphytes on H. wrightii occurred mainly associated with rhizomes, but also tendrils of H. muscif

Abstract:

An epilithic benthic algae functions as a primary producer living on rock substrates. The Autotrofic Index (AI) was measured to understand the level of water pollutions by quantifying an autotrofy organism. This research determined water quality of Pitap river based on the autotrofic level of an epilithic benthic algae and to understand the correlation between the autotrofic level and physicochemical parameters. The measurement of water quality based on Ash-Free Dry Mass (AFDM), the amount of chlorophyll-a and physicochemical parameters were taken every month with two repetitions on September

Abstract:

On Ellesmere Island, in the Canadian Arctic, dark-colored biofilms proliferate on moist surfaces, including exposed granodiorite outcrops. Transmission electron microscopy of these biofilms indicates that complex epilithic microbial communities developed, consisting of cyanobacteria and fungi symbiotically associated in a lichen, along with a consortium of free-living algae and gram-negative bacteria. The epilithic cyanobacteria and bacteria were shown to extensively precipitate phosphatic minerals, ranging from relatively large polyphosphate granules (approximately 250 nm in diameter) within

Abstract:

Phytokarst is spectacularly developed on the hard, finely crystalline dolostones of the Oligocene–Miocene Bluff Formation and to a lesser extent on the soft limestones of the Pleistocene Ironshore Formation on Grand Cayman. The black weathered surfaces, which are a reflection of an organic coating, contrast sharply with the white colour of the unaltered host rocks, which lack an organic coating. On the dolostones this organic coating is formed principally of fungal(?) sporangia and spores associated with mucilage along with lesser numbers of algae and bacteria.

Abstract:

We studied the periphyton in two small lakes acidified experimentally with either sulfuric or nitric acid. For comparison, we monitored periphyton in one previously acidified (sulfuric) lake and in two neutral lakes. Net photosynthesis declined in epilithic periphyton in the middle littoral zone (1–2 m) of both recently acidified basins in response to reduced concentrations of dissolved inorganic carbon. Dark respiration and taxonomic composition remained largely unchanged in this zone. Attached filamentous algae proliferated early [Formula: see text] in the upper littoral zone (< 1 m) of t
