Land-use changes and agricultural intensification have been attributed as the main anthropogenic drivers of declines in insect pollinators. Anthropogenic coastal heathlands are one of the ecosystems that have suffered the most from these intensifications, as traditional management practices have discontinued and only 10% of last century´s coastal heathlands remain. We collected data during the field season of 2022 on pollinator communities with emphasis on bumblebees, in two different habitat types: open and degenerate heathlands in an UNESCO Biosphere Reserve in Western Norway. Here, we aim to get an insight into how pollinator communities may change as more heathlands are left without active management practices like prescribed burning and livestock grazing. Species composition varied between the two habitat types. Degenerate heathlands typically had a higher abundance of some relatively common species in Norway, like B. pratorum, while the red-listed species B. muscorum was recorded exclusively in open heathlands. B. jonellus was more abundant in degenerate sites despite being known to forage on Ericaceae. This may be due to an additional floral diversity and nesting/over-wintering sites here compared to the open sites. Further research should explore potential impacts of landscape characteristics like fragmentation and land-use change on the abundance and diversity of pollinators in heathlands.

A stable supply of high-quality forage is essential for the economic sustainability of milk and meat production, the most important agricultural sectors in Norway. Successful forage production relies on selecting species, cultivars, and seed mixtures suited to the diverse agroecological conditions, which vary widely in latitude and altitude. Climate change modifies production boundaries unpredictably. Without on-farm performance data, there is a risk of recommending new varieties or seed mixtures that underperform in farmers' fields. To address this, we propose the tricot method: a participatory, large-scale, and cost-effective testing approach where farmers test new seed mixtures directly in their fields. This approach involves many farmers in conducting small, simple experiments. Each trial consists of an incomplete block with three options out of the total ten options in the trial. Farmers evaluate these options based on predetermined criteria using digital tools. These mini trials, combined with data on management, climate, and soil, are collected into the ClimMob software, which performs statistical analyses and provides feedback. When all data are aggregated, this approach can provide robust statistical results on optimal seed mixtures for various local conditions. This method also strengthens collaboration between researchers, advisors, and farmers, contributing to more sustainable and resilient agricultural practices.

Abstract
Longitudinal analysis of a patient’s screening history is fundamental to mammography interpretation. Yet existing deep learning models struggle with the irregular, continuous-time nature of screening data, where patient histories involve unevenly timed multi-view exams paired with evolving textual reports. To address this gap, we introduce Dynamo, a novel multi-modal pretraining dynamic framework for longitudinal mammography with two key innovations to model exam timelines as latent trajectories, i.e., a coarse-fine grained exam-level temporal encoder based on Neural Controlled Differential Equations (Neural CDEs) and a Temporal Visual Question Answering (TVQA) loss for query-driven masked token prediction conditioned on temporal context. We perform comprehensive evaluations on downstream tasks including risk prediction using large-scale datasets (EMBED and CSAW-CC), BI-RADS assessment, and breast density classification. Across all benchmarks, Dynamo achieves overall gains over state-of-the-art vision-only and CLIP-style models, improving both calibration and temporal reasoning. On the EMBED dataset, representative gains include 11.81% relative reduction in Risk Prediction’s Brier Score, 3.59% relative improvement in BI-RADS ϰ, and 2.39% relative improvement in BI-RADS AUC in zero-shot settings.
