Mycosporine-Like Amino Acids and Marine Toxins - The Common and the Different

open access: yesMarine Drugs, 2008
Marine microorganisms harbor a multitude of secondary metabolites. Among these are toxins of different chemical classes as well as the UV-protective mycosporinelike amino acids (MAAs).

A genome‐integrated CRISPR/Cas12a system enables efficient genetic engineering in Xenorhabdus budapestensis XBD8

open access: yesNew Plant Protection, EarlyView.
We developed a genome‐integrated CRISPR/Cas12a system for Xenorhabdus budapestensis XBD8, which enables precise deletion or replacement of DNA fragments ranging from 379 to 45,168 bp, with a success rate exceeding 90%. Application of this tool for the dynamic regulation of fabclavine‐8 biosynthesis resulted in a 1.90‐fold increase in production ...

Interplanetary frontiers: terraforming from an invasion science perspective

open access: yesOikos, EarlyView.
The pursuit of a multi‐planetary existence represents one of humanity's greatest frontiers. If applied justly, it offers an opportunity to extend its civilization's lifespan amid escalating sustainability crises on Earth. One approach increasingly gaining traction is terraforming, a hitherto theoretical ecological and evolutionary experiment revolving ...

Cyanobacteria and Macroinvertebrate Relationships in Freshwater Benthic Communities beyond Cytotoxicity

open access: yesToxins
Cyanobacteria are harmful algae that are monitored worldwide to prevent the effects of the toxins that they can produce. Most research efforts have focused on direct or indirect effects on human populations, with a view to gain easy accurate detection ...

Recreational and occupational field exposure to freshwater cyanobacteria – a review of anecdotal and case reports, epidemiological studies and the challenges for epidemiologic assessment

open access: yesEnvironmental Health, 2006
Cyanobacteria are common inhabitants of freshwater lakes and reservoirs throughout the world. Under favourable conditions, certain cyanobacteria can dominate the phytoplankton within a waterbody and form nuisance blooms.

Multitrophic alpha and beta diversity of lake plankton across Canada

open access: yesOikos, EarlyView.
Anthropogenic environmental changes impact freshwater biodiversity globally. While biodiversity assessments in freshwater environments have traditionally focused on individual groups of organisms or trophic levels, considering patterns of ‘multitrophic biodiversity' across the food web provides a more comprehensive view of anthropogenic impacts and ...

The Neuroprotective Effect of a Waste Byproduct Obtained From Pomegranate (Punica granatum)

open access: yesPhytotherapy Research, EarlyView.
The Effect of a Waste Byproduct Obtained From Pomegranate on Neurodegeneration. ABSTRACT Pomegranate is an exceptional fruit that can have several beneficial effects on human health. The peel of pomegranate, a waste product, should be recovered as it still contains valuable constituents, including phenolic compounds, minerals and fibre. The recovery of

Physiological and Metabolic Responses of Marine Mussels Exposed to Toxic Cyanobacteria Microcystis aeruginosa and Chrysosporum ovalisporum

open access: yesToxins, 2020
Toxic cyanobacterial blooms are a major contaminant in inland aquatic ecosystems. Furthermore, toxic blooms are carried downstream by rivers and waterways to estuarine and coastal ecosystems. Concerning marine and estuarine animal species, very little is

Effects of Glyphosate on the Planktonic Microbiota: An Experimental Approach

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Glyphosate is one of the most widely used herbicides in the world, including in Brazil, and its dispersion through habitats and surface waters can impact entire aquatic ecosystems. However, experimental studies evaluating the effects of pesticides on whole planktonic communities, considering attributes such as richness, density and composition—
