(A) Longitudinal median section through the gynoecium showing its complex internal morphology with a remaining floral apex and an empty space (asterisk) in the centre of the ovary; arrowheads indicate stigma positions; grey shaded areas indicate potential stigmatic secretion forming an extra-gynoecial compitum across neighbouring stigmas; pollen grains and hypothetical pathways of pollen tubes are given in orange; dashed orange line indicates hypothetical pathway of pollen tube reaching a stigma via growth through the extra-gynoecial compitum; dashed black line indicates area of postgenital carpel union in the centre of the ovary (symplicate region); arrows indicate area of irregular ovary closure shown in (B); placentation is axile with the seeds (green) attached in the distalmost part of the ovary.

Proglacial sediments in High Arctic glacier foreland: A case study of Werenskioldbreen, Svalbard
<p><span>The glacier environment exhibit a high sensitivity to the global climate change leading to progressive deglaciation and the exposure of previously ice-covered land. The newly exposed <a name="_Hlk165289159"></a>terrain provides a valuable opportunity to observe rapid ecosystem changes, such as the accumulation of glacial sediments, the development of soil-forming and progressive alterations in water and biogeochemical cycles. While developing hydrological and hydrogeological models for the Werenskioldbreen proglacial expanding zone, we encountered a significant problem due to insufficient data for parameterizing glacial sediments, constituting the environment for water flow and storage. These data provide detail insight into the physicochemical parameters of glacial sediments and classify them in terms of grain size distribution, hydraulic conductivity, pH, and C<sub>org</sub>, N<sub>t </sub>and P<sub>t</sub> contents. </span><span>Samples for macroscopic examination and further laboratory analysis were collected from each different proglacial sediment in the profile. Macroscopic characterisation in the field was carried out in accordance with standards <span><span>PN-EN ISO 14688-1 and PN-EN ISO 14688-2 introduced into the catalogue of Polish Standards in 2006 and are cited in PN-EN 1997-2:2009, known as Eurocode 7: Geotechnical engineering design - Part 2: Identification and investigation of soils.<br></span></span></span><span><span><span>More information on the data acquisition methodology is included in the publication (same title) or can be obtained through the contact provided.</span></span></span></p>
