Landrace cereals have become more popular among organic farmers in Europe. However, little is known about the response of landraces to environmental conditions and farmers’ management compared to modern cultivars. A co-designed field experiment, informed by Swedish farmers’ experiences of landrace cereals, was used to investigate how traits valued by organic farmers differ between four landrace and three modern varieties of spring wheat (Triticum aestivum L.) under different environmental conditions and depending on nutrient applications. The experiment was organically managed and consisted of four randomized complete blocks in four environments, comprising two sites during two consecutive years. The varieties responded similarly to fertilization. The most recent modern variety had the highest grain yield of all varieties but the lowest protein content. At low or medium initial availability of nitrogen, landraces were shown to yield similarly to modern organic varieties, give high and stable protein content, and in addition suppress weeds better and produce higher straw yields. In one experimental environment, the initial amount of soil mineral nitrogen was high, and all four landraces yielded considerably less than all modern varieties. These results show the potential for landraces to provide both food and ecosystem services under low-input organic conditions.

Abstract
Schistidium arizonense is described as a new species from the US states of Arizona, New Mexico, and Texas. It belongs to section Atrofusca, but unlike most other taxa of the section, it is not a pure calcicole and also occurs on acidic substrates. The species is characterized by a combination of usually green coloration, fusiform perichaetia, perforated and fragile peristome teeth that are usually split in the upper part, flat or narrowly recurved leaf margins, and long-decurrent perichaetial leaf hairpoints. Based on sequences of the ITS region, the taxon is closely related to S. helveticum, which is congruent with morphological similarities, including similar size, the lack of stomata, and mostly absent or short hairpoints on vegetative leaves. Schistidium arizonense is, however, most likely to be confused with the widespread and highly variable S. crassipilum, which appears to be more distantly related.

Abstract Atmospheric deposition is a critical driver of biogeochemical cycling in forest ecosystems. Among the pathways of deposition, throughfall (TF) — precipitation that has interacted with the forest canopy — plays a significant role in the input of atmospheric substances and canopy leachates to the forest floor. We investigated the influence of airborne pollen deposited in TF on its chemical composition across 60 Level II plots of the ICP Forests network in eight European countries. Based on 196 TF samples collected during the 2018 early vegetative season, we identified 53 pollen taxa, with Pinus , Picea , Fagus , and Quercus accounting for 91.4% of the total grains. Linear mixed-effects models revealed significant positive links between pollen deposition rates and TF fluxes of several ions, especially potassium (K⁺), which was explained by pollen abundance of all four main tree genera. Additionally, pollen of broadleaved taxa ( Fagus , Quercus ) influenced fluxes of the non-purgeable organic carbon (NPOC), dissolved organic nitrogen (DON), ammonium (NH 4 + ), and phosphate (PO 4 3− ). Conversely, broadleaved pollen showed a weak negative link with nitrate (NO₃⁻) fluxes, even if its interpretation requires a cautious approach, as several non-mutually exclusive pathways could explain it. Fractionation of the DOC pools highlighted a higher potential for microbial origin in broadleaves than in conifers. These findings provide the first continental-scale evidence of a link between pollen and TF water chemistry, concurrently analyzed on each water sample. This study underscores the ecological significance of pollen beyond plant reproduction and the need to consider flowering phenology and pollen release in forest deposition and nutrient assessments.
