Compostable and Recyclable Baroplastic Triblock Copolymers Enable Low‐Energy Polymer Processing

Small, EarlyView.
Baroplastic Poly(L‐lactide)‐block‐poly(ethylene glycol)‐block‐poly(L‐lactide) triblock copolymers enable ambient‐temperature processing under moderate pressure, reducing energy demand while preserving polymer integrity. The materials show rapid industrial compostability, effective chemical and physical recyclability, and compatibility with heat ...

Ecotoxicological Evaluation of Organic Sunscreens Used Worldwide, Alone and in Mixture, on Terrestrial Plants

Environmental Toxicology, EarlyView.
ABSTRACT The environmental hazards of sunscreens are discussed worldwide. However, there are few ecotoxicological studies on these compounds alone for edaphic organisms, and none for their mixtures. Avobenzone (1 and 10 ng/L), octocrylene (10 and 100 μg/L), and oxybenzone (2 and 20 μg/L), alone and in binary combinations (between the lowest and the ...

LC-MS/MS-based proteome profiling in Daphnia pulex and Daphnia longicephala: the Daphnia pulex genome database as a key for high throughput proteomics in Daphnia

BMC Genomics, 2009
Background Daphniids, commonly known as waterfleas, serve as important model systems for ecology, evolution and the environmental sciences. The sequencing and annotation of the Daphnia pulex genome both open future avenues of research on this model ...

Phenotypically Plastic Responses to Predation Risk Are Temperature Dependent [PDF]

, 2019
Predicting how organisms respond to climate change requires that we understand the temperature dependence of fitness in relevant ecological contexts (e.g., with or without predation risk).

Toxicity of Four Common Environmental Chemicals Across Caenorhabditis elegans Life Stages Supporting the One Health Concept

Environmental Toxicology, EarlyView.
ABSTRACT Pesticides and pharmaceuticals are among the most common chemical groups in waterbodies and soils, and their universal distribution raises concerns about potential adverse effects on nontarget organisms and humans. Reproductive output disruption is of particular concern, as it transposes effects from the individual to the next generations at ...

The control of indirect effects of biomanipulation [PDF]

, 1992
Results from long-term investigations on biomanipulation show that indirect effects are at least as important as direct effects are for the stability of biomanipulation.

Effects of Glyphosate on the Planktonic Microbiota: An Experimental Approach

Environmental 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—

Vitamin C Content in Daphnia sp. Enriched with L-ascorbic Acid Ethyl Cellulose at Different Enrichment Period

Jurnal Akuakultur Indonesia, 2008
Daphnia with a density of 10,000 ind./l medium were enriched with either 0.1, 0.5 or 1 g l-ascorbic acid ethyl cellulose (VC) per l culture medium. In this triplicate experiment, Daphnia were enriched with VC in a 12 litre aquaria for 0, 3, 6 or 9 h ...

Identifying invertebrate invasions using morphological and molecular analyses: North American Daphnia ‘pulex’ in New Zealand fresh waters [PDF]

, 2012
We used a DNA barcoding approach to identify specimens of the Daphnia pulex complex occurring in New Zealand lakes, documenting the establishment of non-indigenous North American Daphnia 'pulex'.
