Incorporating environmental DNA metabarcoding for improved benthic biodiversity and habitat mapping

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Seafloor imagery is commonly used to collect information about the distribution of benthic organisms in order to generate habitat and biodiversity maps. Recent advances in genomics (e.g., environmental DNA; eDNA) show potential to complement video surveys for habitat mapping, but there have been few examples testing this.

Assessment of the water quality of ten Waikato lakes based on zooplankton community composition. CBER Contract Report No. 60 [PDF]

open access: yes, 2007
Zooplankton communities were documented from ten Waikato lakes from net haul samples collected in late 2006 and from species hatched from diapausing eggs in sediments collected in early 2007.

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—

Effect of large- and small- bodied zooplankton on phytoplankton in a eutrophic oxbow [PDF]

open access: yes, 2005
Macrozooplankton and microzooplankton effects on the phytoplankton were measured in situ in a eutrophic lake. Indigenous phytoplankton were incubated for 5 days in 301 mesocosms with either the macro- and microzooplankton (complete), microzooplankton ...

Nanomaterials' Multigenerational Effects by Single and Joint Exposure in Non‐mammalian Models

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Nanotoxicology has mainly focused on single‐generation studies, leaving multigenerational toxicity underexplored. Having animal welfare recently gained importance, we aimed to provide the state‐of‐the‐art of knowledge about multigenerational effects in non‐mammalian models in the case of nanomaterials (NM) single and joint exposure to other ...

Effects of environmental factors on species diversity of rotifers using biodiversity indicators and canonical correlation analysis (CCA) [PDF]

open access: yesبوم‌شناسی آبزیان, 2017
Rotifers are microscopic aquatic animals of phylum Rotifera, live in a diverse range of aquatic habitats. They are important in ecology of freshwater ecosystems by recycling nutrients and can alter trophic dynamic of planktonic communities.

Can manipulative parasites modify host‐mediated trophic effects? Experimental evidence from Schistocephalus solidus and three‐spined sticklebacks

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Parasites can alter host traits, thereby reshaping host interactions and modifying density‐ and trait‐mediated effects in trophic cascades. But despite increasing research in parasite ecology, the cascading effects of parasitism from individual hosts to population and ...

The significance of phosphorus in algae growth and the subsequent ecological response of consumers

open access: yesJournal of Freshwater Ecology, 2022
Human activities have substantially disrupted phosphorus (P) cycles in the ecosystem, affecting producers and consumers along the food chain. To assess the ecological effects of imbalanced P on producers as well as consumer reactions to changes in food ...

Sterols of the rotifer.

open access: yesNIPPON SUISAN GAKKAISHI, 1979
The sterol components of the rotifer, Brachionus plicatilis, the marine type of Chlorella, Chlorella saccharophila, and the baker's yeast, Saccharomyces cerevisie, were investigated by using combined gas-liquid chromatography and mass spectrometry. The rotifer contained 24-methylcholesta-7, 22-dienol as a major sterol (61% of total sterols), and other ...

FINE STRUCTURE OF THE CILIA OF ROTIFERS [PDF]

open access: yesThe Journal of Cell Biology, 1961
The fine structure of the coronal cilia of the rotifer Philodina citrina has been studied in detail. Specimens were fixed with OsO4 and embedded in butyl—methyl methacrylate, Epon 812, or Vestopal and sectioned with a Porter-Blum microtome. The details of structure of the rootlets, basal bodies, basal plates, and free cilia are described.
