Periphytic algal biomass in two distinct regions of a tropical coastal lake

Acta Limnologica Brasiliensia
AIM: This study assessed the phycoperiphyton biomass in two regions submitted to different human impacts on Juara Lake, a coastal ecosystem with multiple uses, to order to test the hypothesis that the sampling sites that receive domestic sewage shows ...

Influence of substratum surface roughness on periphytic algal community structure in a shallow tropical reservoir Influência da rugosidade do substrato sobre a estrutura da comunidade de algas perifíticas em reservatório raso tropical

Acta Limnologica Brasiliensia, 2012
AIM: This study aimed to evaluate the algal periphytic community structure on substrates with differing surface roughness in early and longer-term colonization; METHODS: Periphyton was sampled after 30 days (June 24 to July 24, 2008) and 5 days (July 07 ...

Effects of climate on size structure and functioning of aquatic food webs [PDF]

, 2010
In aquatic food webs, the role of body size is notoriously strong. It is also well known that temperature has an effect on body size. For instance, Bergmann’s rule states that body size increases from warm to cold climates.

Decrease of diatom biovolume in biofilms exposed to arsenic

, 2015
La pollution par l’arsenic est un problème mondial. Les eaux (de surface et souterraines) en sont la voie principale de contamination. Nous avons mené une expérience visant à étudier les effets de ce métal sur les descripteurs fonctionnels et structurels des communautés de diatomées benthiques (Barral-Fraga et al., 2015).

Lack of correlation between in vitro and within patient measures of P. aeruginosa biofilms in cystic fibrosis

Heliyon
Current in vitro biofilm modelling of the opportunistic pathogen, Pseudomonas aeruginosa (PA) in people with cystic fibrosis (PwCF) is limited in its ability to mimic the complexities of the cystic fibrosis (CF) lung environment.

Prelimnary biovolume characterisation of zooplankton community in Omi Dam, Nigeria

, 2010
The study examined the zooplankton biomass in Omi dam to identify which specie(s) among the major ones under consideration, contributed most to the recruitment and growth of fish in the dam. Rotifera took the dominance in terms of species, followed by cladocerans and copepod respectively.

Planktonic Cyanobacteria of the tropical karstic lake Lagartos from the Yucatan Peninsula, Mexico

Revista de Biología Tropical, 2013
The tropical karstic lakes on the Mexican Caribbean Sea coast are numerous. However, there is an enormous gap of knowledge about their limnological conditions and micro-algae communities. In the present study, surface water samples were collected monthly
