Using metabarcoding and droplet digital PCR to investigate drivers of historical shifts in cyanobacteria from six contrasting lakes

Scientific Reports, 2022
The frequency and intensity of cyanobacterial blooms is increasing worldwide. Multiple factors are implicated, most of which are anthropogenic. New Zealand provides a useful location to study the impacts of human settlement on lake ecosystems.

Freshwater fish diversity information system as a basis for sustainable fishery [PDF]

, 2004
Our freshwater fish diversity is poorly studied. There is no proper documentation on freshwater fish resources of India. Due to irrational fishing practices, environmental aberrations like reduction in water volume, increased sedimentation, water ...

GIS for aquatic animal health management: a framework for tailored project development

Frontiers in Marine Science
Although Geographic Information Systems (GIS) have proved to be reliable tools for animal health management, their implementations in the aquatic animal health (AAH) domain are scarce, likely because they require expertise in GIS technologies, the ...

Seasonal variation in activity and nearshore habitat use of Lake Trout in a subarctic lake

Movement Ecology, 2023
Background In lake ecosystems, predatory fish can move and forage across both nearshore and offshore habitats. This coupling of sub-habitats, which is important in stabilizing lake food webs, has largely been assessed from a dietary perspective and has ...

Characterisation of host growth after infection with a broad-range freshwater cyanopodophage [PDF]

, 2014
Freshwater cyanophages are poorly characterised in comparison to their marine counterparts, however, the level of genetic diversity that exists in freshwater cyanophage communities is likely to exceed that found in marine environments, due to the habitat

The influence of the freshwater environment and the biological characteristics of Atlantic salmon smolts on their subsequent marine survival [PDF]

, 2012
Atlantic salmon have declined markedly in the past 20-30 years throughout their range. Much of the focus for this decline has been on increased mortality during the marine phase of the life cycle.

Can you see the algae for the slime? Temporal patterns of biofilm food quality and quantity in lowland rivers

Ecosphere, 2023
Animals must invest some portion of their metabolism to activities related to physiological maintenance and the remainder to processes related to the production of new biomass for growth and reproduction.

Glochidia ecology in wild fish populations and laboratory determination of competent host fishes for an endemic freshwater mussel of south-western Australia [PDF]

, 2012
Glochidia (parasitic larvae) of freshwater mussels generally require a fish as a host. Westralunio carteri Iredale, 1934 (Bivalvia : Hyriidae), the only freshwater mussel found in south-western Australia, was listed as Vulnerable, but recently changed to

Biomass DNA: An Emerging Building Block for Advanced Materials

Advanced Materials, EarlyView.
Biomass DNA is rapidly emerging from its traditional role as a genetic blueprint to serve as a versatile abundant, highly programmable polymeric building block. This review highlights the transformation of macroscopic bulk biomass DNA into next generation of functional materials, spanning from dynamic hydrogels, sustainable bioplastics, and high ...
