The bay barnacle Amphibalanus improvisus (Darwin, 1854) in the Pleistocene of Europe? A review of Pleistocene Balanidae of northern Central Europe

Journal of Quaternary Science, Volume 39, Issue 4, Page 547-565, May 2024.
ABSTRACT The bay barnacle Amphibalanus improvisus (Darwin, 1854) has been found in Northern Germany in brackish marine sediments of the Holsteinian interglacial. Whereas the cause of the contemporary distribution of this species is anthropogenic and there is evidence that it has resulted mainly from shipping, the fossil findings demonstrate that A ...

Shoreline slope influences movements of larval lampreys over dewatered substrate

Aquaculture, Fish and Fisheries, Volume 4, Issue 1, February 2024.
Controlled laboratory study of larval lamprey movement capabilities over dewatered substrates following dewatering. Lamprey habitats, in fine sediments near stream margins, are regularly dewatered. This study helps refine guidance on best management practices to limit impacts to lampreys during dewatering events.

QUALITY FEATURES OF PARTHENOCARPIC PEARS COLLECTED FROM TREES GROWN ON DIFFERENT ROOTSTOCKS

Acta Scientiarum Polonorum: Hortorum Cultus, 2015
In countries where spring frost frequently causes damage to pear flowers, cropping is possible through natural and induced parthenocarpy. The tendency to bear parthenocarpic fruit is a genetic feature so it differs between cultivars.

Authigenic‐cemented pebbles formed during Pleisto–Holocene transgression of gently inclined coastal plains

Sedimentology, Volume 71, Issue 2, Page 486-508, February 2024.
ABSTRACT From numerous modern gently inclined coastal areas and deltas around the world carbonate‐cemented sandstone slabs and pebbles have been reported. Such sandstones collected at the coast of the German North Sea and the Mediterranean Sea (Rhône Delta) are cemented by calcite derived from the anaerobic oxidation of methane, as evidenced by ...
