High levels of seed dispersal by a declining wintering population of migratory geese
Freshwater Biology, Volume 69, Issue 12, Page 1857-1870, December 2024.Abstract Ducks are known to be important seed dispersers, but the role of geese in plant dispersal is less clear. Wintering populations of migratory geese are undergoing rapid changes in distribution and habitat use in response to climate change and changes in land use, and the implications for seed dispersal have not previously been studied.

Boreas, Volume 53, Issue 4, Page 504-524, October 2024.Biological proxy analyses, element composition, and stable isotope ratios at the Lower Palaeolithic locality of Schöningen provide evidence for repeated variations in climate, hydrology and catchment vegetation cover during MIS 9. Quantitative temperature reconstructions with the Mutual Ostracod Temperature Range method show colder winter temperatures ...

The Plant Journal, Volume 119, Issue 6, Page 2797-2815, September 2024.SUMMARY The conquest of land posed severe problems to plants which they had to cope with by adapting biosynthetic capacities. Adaptations to respond to UV irradiation, water loss, pathogen and herbivore defense, and the earth's pull were essential. Chemical compounds alleviating these problems can be synthesized by the phenylpropanoid pathway, the core

Morphological variability of oospores of Chara baueri A. Braun (Characeae)
Acta Societatis Botanicorum Poloniae, 2011 The shape and size of present-day specimens of Chara baueri are described. C. baueri is believed to have practically died out in Europe. Oospores of specimens of C. baueri collected in Kazachstan were subjected to morpholgical analysis.

Earth Surface Processes and Landforms, Volume 49, Issue 10, Page 3139-3157, August 2024.Offshore wind farm datasets record the response of low‐relief coastal landscapes to rising sea levels in the past. The maps show evidence of former terrestrial peatlands, preserved offshore, prior to being covered by the modern North Sea. Abstract Low‐relief coastal landscapes are at major risk of rising sea levels, as vertical changes in relative sea ...
