Synergistic growth, metabolic products, and matrix quantification in dual-species biofilms of oral pathogens [PDF]

open access: yesJournal of Applied Oral Science
Biofilms exhibit virulence traits that promote microbial protection, such as an extracellular matrix composed of exopolysaccharides (EPS), and contribute to host tissue damage via acid production.

Polyp size predicts metabolic rates across diverse tropical coral species [PDF]

open access: yesCommunications Biology
Body size is a fundamental driver of metabolism, yet it remains unclear whether colonial organisms such as corals conform to the universal ¾-power scaling law. As climate change accelerates metabolic demands, characterizing these scaling relationships is

Morphometric variability of Carabidae as an indicator of ecological restoration of revitalized habitats in the European important protected landscape area of the Danube floodplains [PDF]

open access: yesPeerJ
Revitalization measures currently represent an important tool in ecological practice for the recovery of disturbed habitats, and their effectiveness is increasingly assessed using bioindicator groups, including ground beetles (Carabidae).

Similar growth potentials of cyanobacteria and algae explain their coexistence in desert soils [PDF]

open access: yesScientific Reports
In deserts that cover one-third of the Earth’s terrain, soil cyanobacteria and algae are key carbon dioxide (CO2) fixers because few other plants can tolerate intense solar radiation, prolonged desiccation, and extreme temperature shifts.

Toxic effects of chlorpyrifos, cypermethrin and glyphosate on the non-target organism Selenastrum capricornutum (Chlorophyta)

open access: yesAnais da Academia Brasileira de Ciências, 2021
The toxic effects of the insecticides chlorpyrifos and cypermethrin, and the herbicide glyphosate on the growth, biovolume and ultrastructure of the green microalgae Selenastrum capricornutum were evaluated.

Periphytic algal biomass in two distinct regions of a tropical coastal lake Biomassa de algas perifíticas em duas regiões distintas de uma lagoa costeira tropical

open access: yesActa Limnologica Brasiliensia, 2012
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 ...

Changes in Phytoplankton Community Composition and Phytoplankton Cell Size in Response to Nitrogen Availability Depend on Temperature

open access: yesMicroorganisms, 2022
The climate-driven changes in temperature, in combination with high inputs of nutrients through anthropogenic activities, significantly affect phytoplankton communities in shallow lakes. This study aimed to assess the effect of nutrients on the community

Phytoplankton functional and morphological groups as indicators of environmental variability in a lateral channel of the Upper Paraná River floodplain

open access: yesActa Limnologica Brasiliensia, 2014
AIM: Models of phytoplankton functional classification based on functional (FGs) and morphological (MBFGs) traits can be an important tool in aquatic monitoring.

Combined use of chlorophyll a and phycocyanin fluorescence sensors for quantification and differentiation of phytoplankton: a useful approach for small surface water bodies

open access: yesActa Biologica Slovenica, 2018
Sensors based on in vivo measurements of photosynthetic pigments fluorescence enable real-time phytoplankton monitoring with high spatial and temporal resolution. A combination of chlorophyll a (CHL) and phycocyanin (PC) fluorescence sensors was used for
