New records of phytoplankton for Bangladesh. 2. Cryptophyceae and Synurophyceae

Abstract

This study presents two species of Rhodomonas, four species of Chroomonas, six species of Cryptomonas and Cryptochrysis minor, Cyanomonas coeruleus, Chrysodidymus synuroideus and Mallomonas akrokomos. These species have been reported from some ponds of Mathbaria in Pirojpur and Bakerganj of Barisal district in Bangladesh.

A taxonomic account on the phytoplankton of a pond receiving textile industrial effluents

“…Phytoplankton were identified with the help of a Nikon compound microscope (Japan) at magnifications ranging from ×150 -× 1500. Desikachary (1959), Islam and Begum (1970), Prescott (1982), Huber-Pestalozzi (1983), Bold and Wynne (1985), Islam and Irfanullah (2005a, b, c) and Khondker et al (2006Khondker et al ( , 2007a were consulted for the identification of phytoplankton species. Table 1 shows annual ranges of some physicochemical variables from the studied pond.…”

“…In Bangladesh, a number of research works have been carried out on phytoplankton from a range of habitats and localities (Islam and Begum 1970, 1987, Islam and Irfanullah 2005a, b, c, 2006, Khondker et al 2007a. Phytoplankton from organically polluted ponds were worked out by Islam and Khatun (1966), Islam and Nahar (1967), and Khondker et al (1990), but there exists very little information on qualitative aspects of phytoplankton from the polluted habitats contaminated by industrial wastes.…”

New records of phytoplankton for Bangladesh: Division - Cryptophyta

“…Most of them are planktonic and commonly called cryptomonad algae. In Bangladesh, a number of studies were carried out on this phytoplankton (Islam and Khondoker, 1997;Khondoker et al, 2007;Alfasane et al, 2010;Gani et al, 2014). So far, a total of 9 genera and 19 species were reported (Ahmed et al, 2009).…”

New records of phytoplankton for Bangladesh. 6. <i>Lepocinclis</i> Perty, <i>Strombomonas</i> Defl., <i>Astasia</i> Dujardin, <i>Menoidium</i> Perty

“…The taxa were found to occur in the plankton samples collected from different pond ecosystems of Mathbaria of Pirojpur district and Bakerganj of Barisal district. New reports of phytoplankton for Bangladesh from the same locality have also been published elsewhere (Khondker et al 2006(Khondker et al , 2007a(Khondker et al , b, c, d, 2008.…”
