Migration of Net Phytoplankton and Zooplankton in Mendum’s Pond, New Hampshire [PDF]

open access: yes, 2006
The study examines the vertical distribution and migratory behavior of net phytoplankton and zooplankton of Mendum’s Pond in Barrington, N.H. The cyanobacteria, Microcystis and Aphanocapsa were the dominant net phytoplankton in this lake.

Morphological and life‐history trait plasticity of two Daphnia species induced by fish kairomones

open access: yesEcology and Evolution
Daphnia can avoid predation by sensing fish kairomones and producing inducible defenses by altering the phenotype. In this study, the results showed that the morphological and life‐history strategies of two Daphnia species (Daphnia pulex and Daphnia ...

Hurdles in investigating UVB damage in the putative ancient asexual Darwinula stevensoni (Ostracoda, Crustacea) [PDF]

open access: yes, 2013
Ostracoda or mussel-shrimps are small, bivalved Crustacea. Because of their excellent fossil record and their broad variety of reproductive modes, ostracods are of great interest as a model group in ecological and evolutionary research.

Advantages of Hopping on a Zig-zag Course

open access: yes, 2004
We investigate self-moving particles which prefer to hop with a certain turning angle equally distributed to the right or left. We assume this turning angle distribution to be given by a double Gaussian distribution. Based on the model of Active Brownian

EURO-ECOLE: Assessment of the Bioavailability and Potential Ecological Effects of Copper in European Surface Waters ; subproject 4: Evaluation and improvement of the ecological relevance of laboratory generated toxicity data [PDF]

open access: yes, 2002
This report summarizes the acute and chronic toxicity of copper to algae, Daphnia and a few other freshwater species in standard laboratory test water and a wide range of natural surface waters (collected across Europe), with a wide range of pH ...

Modulation of PFOA (perfluorooctanoic acid) uptake in Daphnia (Daphnia magna) by TiO2 nanoparticles

open access: yesComparative Biochemistry and Physiology Part C: Toxicology & Pharmacology
The hydrophobic surface of plastics adsorbs hydrophobic persistent organic pollutants (POP) such as Perfluorooctanoic acid (PFOA). The potential for hydrophobic nanoparticles such as titanium dioxide (TiO2) to associate with PFOA and alter accumulation rates has not been investigated.
