Temperature Effect on Exploitation and Interference Competition among Microcystis aeruginosa, Planktothrix agardhii and, Cyclotella meneghiniana

The Scientific World Journal, 2015
We studied the effect of temperature (18 and 30°C) on growth and on the exploitation and interference competition of three species: Microcystis aeruginosa (MIJAC), Planktothrix agardhii (PAT), and Cyclotella meneghiniana (CCAP). Coculturing the organisms

Microbial synthetic biology for plant metabolite production: a strategy to reconcile human health with the realization of the UN Sustainable Development Goals

Biofuels, Bioproducts and Biorefining, Volume 17, Issue 6, Page 1485-1495, November/December 2023., 2023
Abstract Plants produce a wide range of secondary metabolites that provide an array of benefits for human health. Challenges of native host production systems such as excessive land use, large carbon footprints, long production times, and high production costs often make plant‐based production of these critical metabolites inefficient and unsustainable.

Functional diversity of experimental annual plant assemblages drives plant responses to biological soil crusts in gypsum systems

Functional Ecology, Volume 37, Issue 3, Page 488-503, March 2023., 2023
Read the free Plain Language Summary for this article on the Journal blog. Abstract Biological soil crusts (BSC) are complex biotic aggregates comprised of lichens, cyanobacteria, algae and other micro‐organism that are known to differently affect plant development along life cycle by selecting plant functional traits based on species‐specific effects.

Digitizing the coral reef: Machine learning of underwater spectral images enables dense taxonomic mapping of benthic habitats

Methods in Ecology and Evolution, Volume 14, Issue 2, Page 596-613, February 2023., 2023
Abstract Coral reefs are the most biodiverse marine ecosystems, and host a wide range of taxonomic diversity in a complex spatial community structure. Existing coral reef survey methods struggle to accurately capture the taxonomic detail within the complex spatial structure of benthic communities.

Nocturnal dissolved organic matter release by turf algae and its role in the microbialization of reefs

Functional Ecology, Volume 36, Issue 8, Page 2104-2118, August 2022., 2022
Read the free Plain Language Summary for this article on the Journal blog. Abstract The increased release of dissolved organic matter (DOM) by algae has been associated with the fast but inefficient growth of opportunistic microbial pathogens and the ongoing degradation of coral reefs.

Acute Exposure to Microcystin‐Producing Cyanobacterium Microcystis aeruginosa Alters Adult Zebrafish (Danio rerio) Swimming Performance Parameters

Journal of Toxicology, Volume 2011, Issue 1, 2011., 2011
Microcystins (MCs) are toxins produced by cyanobacteria (blue‐green algae), primarily Microcystis aeruginosa, forming water blooms worldwide. When an organism is exposed to environmental perturbations, alterations in normal behavioral patterns occur.

Comparison between biofloc technology system and aquamimicry in the cultivation of Litopenaeus vannamei in lined ponds in Southern Brazil

Boletim do Instituto de Pesca, 2023
This work compared biofloc technology and aquamimicry technologies in Litopenaeus vannamei lined ponds, using a density of 60 shrimp·m-2. The experiment lasted 120 days, with two treatments, bioflocs (TBio) and aquamimicry (TMi), and three replications ...
