<p style="font-size:var(--text-lg); color:var(--color-text-muted); line-height:1.65; margin-bottom:var(--space-5);">Grid-level density and habitat projections for moose (<em>Alces alces</em>), roe deer (<em>Capreolus capreolus</em>), and grey wolf (<em>Canis lupus</em>) across 374 Scandinavian grid cells under five IPCC Shared Socioeconomic Pathways — designed for foresters, game hunters, and wildlife managers.</p>

<p class="text-sm text-muted" style="line-height:1.7; margin-bottom: var(--space-5);">The tool couples hierarchical and stacked species distribution models — integrating climate, vegetation, and land-cover predictors — with ODE-based wolf–ungulate trophic interaction layers (Guisan & Thuiller, 2005; Chapron et al., 2016). The map slider restricts projections to 2025–2060, while per-grid time series retain the full 1999–2060 record so stakeholders can read projections against baseline variability. The application runs entirely in-browser via stlite; no install is required.</p>

<p style="font-size:var(--text-lg); color:var(--color-text-muted); line-height:1.65; margin-bottom:var(--space-5);">An in-browser decision-support tool for the black alder (<em>Alnus glutinosa</em>) — alder leaf beetle (<em>Agelastica alni</em>) — tachinid parasitoid (<em>Meigenia mutabilis</em>) — insectivorous-bird ecoepidemic system. Pick any of 41 Natura 2000 alluvial-forest sites across Europe on the interactive map and the 23 model parameters auto-calibrate from a continuously-updated literature metadatabase.</p>

<p class="text-sm text-muted" style="line-height:1.7; margin-bottom: var(--space-5);">AlderGuard couples a within-season 4-state ODE system (susceptible larvae, parasitised larvae, adult parasitoids, defoliation) with an annual Beverton-Holt discrete map for beetle reproduction, parasitoid overwinter survival, and canopy feedback. A scheduled GitHub-Actions literature agent continuously grows the parameter metadatabase from OpenAlex, Europe PMC, Semantic Scholar, and Crossref, feeding reviewed values and 95 % confidence intervals onto every slider. Companion Python (<code>pip install git+...#subdirectory=alderguard-py</code>) and R (<code>remotes::install_github</code>) packages reproduce every analysis programmatically.</p>
