12 protostelid (microscopic slime mold) species were found in 15 samples of aquatic and terrestrial litter taken from northeast German ponds, 90% of species (including all of the most common) being found in both types of litter. Terrestrial litter contained more protostelids (14% of cultures) than aquatic litter (12%), and the water column contained none.

When tomatoes were inoculated with the fungal endophyte Acremonium strictum, only 20% of Cotton Bollworm caterpillars survived to adulthood, compared to 54.5% on uninoculated tomatoes, although they still ate the same quantity of leaves.

Tomatoes – Lycopersicum esculentum
Cotton Bollworm – Helicoverpa armigera

In Hainich National Park, and old-growth forest in Germany, leaves in the upper canopy of eight tree species varied in size from 12.9 to 19.4 m2 per kg, were covered in 125 to 313 stomata per mm, contained 95-175mol Nitrogen per m2, and had a delta 13C value (the degree of carbon enrichment compared to inorganic matter, the more negative the higher), of -27.81 to -25.85 parts per thousand (typical of C3 photosynthesis). Sycamore, Hornbeam, Ash, and Linden saplings had a maximum CO2 assimilation rate (Amax, indicating photosynthetic rate) of 5.0 and 6.4 mumol m–2s–1. Adult Hornbeams had the lowest Amax (10.5), and Ash the highest (16.3). Lower canopy Ash also had the highest Amax (12.0, compared to 5.0-5.6).

Sycamore – Acer pseudoplatanus
Hornbeam – Carpinus betulus
Ash – Fraxinus Excelsior
Linden – Tilia platyphyllos

Fine polymer resin particles 2.4μm in diameter were stained with 7-amino-4-methylcoumarin (AMC), and Chlorella vulgaris (a single-celled alga) was labelled with fluorescein-5-isothiocyanate (FITC). The fine polymer particles were ingested by several groups (chironomids, microcrustaceans, oligochaetes and tardigrads), whereas Chlorella was only taken up by oligochaetes, and over 85% of particles ended up in the top centimetre of sediment within 14 days. In plexiglass sediment cores, <1mm dried alder leaf fine particulate organic matter (FPOM) stayed within the top 2-3cm of sediment, with finer particles deepest. 65-96% of algae settled there were attached to sand, restricting vertical transport.
