Efficient Automatic Pollen Recognition From Fossil Pollen Samples: A High-Resolution Example Record From Palaeolake Kieshofer Moor, Northeastern Germany. [PDF]
We applied the two‐stage, AI‐based TOFSI approach to test automatic pollen recognition with fossil pollen samples. The algorithm performs very well for all major pollen types and other non‐pollen object classes, suggesting that such tools have the potential to substantially increase the efficiency of pollen analysis.

Comparative Analysis of Fire and Explosion Properties of Lycopodium Powder
Lycopodium (L.) clavatum powder, due to its uniform particle size distribution and low equilibrium moisture content, is often used as a reference material and a calibration benchmark for dust combustion and dust explosion studies.

Leaf Damage is Not the Answer! Reduced Herbivore Pressure Does Not Underpin Either Downhill or Uphill Range Shifts. [PDF]
While many plant species are shifting their ranges uphill in response to climate change, a substantial portion of species have exhibited a downhill shift, opposite to the expected response under climate change. We tested the hypothesis that these counterintuitive range shifts may be driven by a reduction in enemy (herbivores and pathogens) pressure ...

Lycoplanines B-D, Three Lycopodium Alkaloids from Lycopodium complanatum
A novel C17N Lycopodium alkaloid (LA), lycoplanine B (1), containing an unusual formyl group, along with two new LAs, lycoplanines C (2) and D (3), were isolated from the whole plant of Lycopodium complanatum.

Shared body plans of lycophytes inferred from root formation of Lycopodium clavatum
Late Silurian to early Devonian lycophytes had prostrate aerial axes, while subordinate organs or subterranean axes were formed around the dichotomies of the axes. The subterranean axes are hypothesized to have evolved into root-bearing axes (rhizophores)
