The last author reported that when heavy rains appeared at the end of the dry season, the pools in the rivers with filamentous algae
and the larvae were washed away by the heavy water flow.
It is also interesting to note that the site where the prawn specimen was caught represents a highly eutrophicated water body with a high cover of opportunistic filamentous algae
(Martin et al.
At the Sven Loven Centre for Marine Sciences' Kristineberg research station on Gullmarsfjorden, researchers from the University of Gothenburg's Department of Biology and Environmental Sciences have developed miniature ecosystems in outdoor aquariums and have been investigating how future ocean warming and ocean acidification could affect the balance between eelgrass and filamentous algae
Two control mesocosms (CM) were filled with approximately 165 L of reservoir water filtered through an 80 [micro]m mesh net to remove zooplankton and most of the larger filamentous algae
The flora and fauna of this shale is dominated by the microfossil groups foraminifera, radiolaria, diatoms, and macrofossil groups like filamentous algae
, cetaceans, sirenians, pinnipeds, fish, birds, ostracod crustaceans, bivalves, gastropods, bryozoans, polychaetes, leaves, and woody plant debris (Buckeridge & Finger 2001).
and detritus were found in 98% of the catfish and represented 85% (mean percent by weight) of gut contents (Table 1).
We have indeed seen explosive growth of filamentous algae
in streams receiving both low and high phosphorus concentrations but very little in the control streams where nutrient concentrations are similar to high-quality reference streams in our region.
In general, filamentous algae
are able to give higher photosynthetic rates per unit biomass (Johansson and Snoeijs, 2002) than perennial macroalgae with a slower growth rate (King and Schramm, 1976; Wallentinus, 1984; Middelboe and Binzer, 2004; Sand-Jensen et al.
Other benthic species that were regularly found in this habitat were the filamentous algae
Cladophora glomerata, Ceramium tenuicorne, Polysiphonia fucoides, and Pilayella littoralis; the bivalves M.
grew well during this time and approximately 75% of the algal mass was removed from the petri dishes weekly with forceps.
Among those with food items (n = 149), insects were most common and occurred in 66% of fish, followed by formulated feed (60%), diatoms (40%), cladocerans (36%), rotifers (35%), filamentous algae
(32%), bryozoan statoblasts (19%), and copepods (12%; Table 1).
By grazing ephemeral filamentous algae
, periwinkles facilitate colonization of larger fleshy macroalgae, such as fucoids and Chondrus crispus (Lubchenco 1980, Lubchenco 1983, Scheibling et al.
Fountain darters, collected within these grids, were found in greatest densities in filamentous algae
But now Adey has proposed that the crucial factor is the washing of the waves over stationary plants, such as the filamentous algae
Besides, in recent years mass development of filamentous algae
has been reported in the northern Baltic Sea and such drifting algal mats may facilitate the spread of the associated invertebrate species at wide distances (Kotta et al.
