The dominance of
pennate diatoms in the fouling film is a ubiquitous observation [9] due to their ability to attach to any surface.
Pennate and centric diatoms respond differently to disturbance.
Key words:
Pennate diatom, Kallar Kahar Lake, District Chakwal, Brackish water.
(44) In contrast, for muscles such as the gastrocnemius, which are in a
pennate arrangement, very high forces are developed in the muscles.
Class 2 Bacillariophyceae (Pennales,
Pennate Diatoms)
Of the nitrogen incorporated by intertidal sedimentary biota (
pennate diatoms, harpacticoid copepods, oligochaetes), benthivorous fishes (mummichog, white sucker), and sand shrimp, 10-30% derived from planktonic diatoms, often through a delayed remineralization and re-incorporation loop.
However, a progression from centric (radially symmetrical) to
pennate (bilaterally symmetrical) forms is evident (Round and Crawford, 1984).
Development of statistical models for prediction of the neurotoxin DA levels in the

During the rainy season,
pennate diatoms and desmids from functional group P (Closterium sp.), Na (Cosmarium sp.
Pennate diatoms typical for sea ice habitat in Alaskan fast ice (Horner and Schrader, 1982; Gradinger et al., 2009b; Manes and Gradinger, 2009) were observed in 100% of all fields of view of all animals examined in May, while we observed only one single diatom cell in a total of 60 fields of view studied in three animals collected in February (Table 1).
