Leeuwenhoek's 1677 paper, the famous ‘letter on the protozoa’, gives the first detailed description of protists and bacteria living in a range of environments. The colloquial, diaristic styleExpand
The Ecology and Palaeoecology of Diatom – Duckweed Relationships
Sediment core analyses suggested major compositional, structural and ecological changes brought about by the Lemna cycles, especially in the submerged macrophyte community and in fish-invertebrate relationships, reveal that duckweed proliferation can result in dramatic ecological changes due to a strong physical ecosystem engineering effect. Expand
History of diatom research in The Netherlands and Flanders
Diatoms were already used in geological research in the second half of the nineteenth century and enabled many twentieth century workers to do applied research for geological and ecological purposes. Expand
It was aimed to use diatoms as representatives of phytobenthos for estimating the ecological status in Upper Sakarya Basin and IDP index which shows a high correlation with total nitrogen was used for the evaluation of the biological status. Expand
Evolution: Fangtastic Venoms Underpin Parasitic Mimicry
A new study reveals the evolutionary origins of fangs and venom in the Nemophini blennies and shows that, in contrast to snakes and lizards, the fangs pre-date the venom. Expand
Mission possible: diatoms can be used to infer past duckweed (lemnoid Araceae) dominance in ponds
A new diatom-based Lemna-indicator metric is developed to help understand the implications of duckweed dominance for the long-term ecology of ponds, and to determine the potential for palaeoecological studies in ponds more generally, is developed. Expand
Genomic evidence for ameiotic evolution in the bdelloid rotifer Adineta vaga
The genome of a bdelloid rotifer, Adineta vaga, is reported and it is shown that its structure is incompatible with conventional meiosis, and abundant evidence of gene conversion is found, which may limit the accumulation of deleterious mutations in the absence of meiosis. Expand
Genetic Exchange among Bdelloid Rotifers Is More Likely Due to Horizontal Gene Transfer Than to Meiotic Sex
It is suggested that bdelloid rotifers evolve asexually but exchange DNA horizontally both within and between species. Expand
Non-overlapping Neural Networks in Hydra vulgaris
This work uses calcium imaging of genetically engineered animals to measure the activity of essentially all of its neurons, and surprisingly finds a series of functional networks that are anatomically non-overlapping and are associated with specific behaviors. Expand
Cellular multifunctionality in the muscle activity of Hydra vulgaris
The results reveal that Hydra’s epitheliomuscular tissue is a multifunctional system that can be flexibly reconfigured to generate different spatiotemporal activity patterns, enabling a structurally simple design to implement a varied behavior output. Expand
