Extinction Debt Paid Off: The Demise of the European Polecat (Mustela putorius) in NE Iberia

open access: yesIntegrative Zoology, EarlyView.
We studied a vanishing polecat population for a decade, until its ultimate demise, using camera trap and roadkill data, landscape descriptors and dietary and toxicological analyses.Polecat favoured farmland and avoided forests and water bodies occupied by the invasive American mink.

Ancient allopolyploidy and specific subgenomic evolution drove the radiation of poplars and willows

open access: yesNature Communications
Allopolyploidy involves the fusion of genomes from different lineages through hybridization and chromosome doubling. However, detecting early allopolyploidy events and understanding the specific subgenomic evolution that contributes to the origin of ...

Spatial Patterns of Avian Stable Isotopes Reveal Ecological Impacts of Climate and Land‐Use Change

open access: yesIntegrative Zoology, EarlyView.
Increased feather δ15N values with pasture coverage reveal an elevated baseline δ15N in grazing landscapes, while broader isotopic niches in farmland habitats reflect agricultural expansion's significant influence on resource use patterns of the avian community.

Chironomid‐based summer temperature reconstruction of the Eemian–Weichselian transition at Lichtenberg, northern Germany

open access: yesBoreas, EarlyView.
Understanding the temperature variability of past interglacial cycles is essential to predict future climates. We present a new summer temperature reconstruction, based on the subfossil chironomid record from a small palaeolake adjacent to the Middle Palaeolithic site of Lichtenberg, northern Germany. The record spans from the Saalian late glacial over

Changing climates and environments within the complex Middle to Late Pleistocene fill of an overdeepened valley at Niederweningen, Switzerland

open access: yesBoreas, EarlyView.
Glacially overdeepened valleys in the northern Alpine Foreland preserve Middle to Late Pleistocene sedimentary sequences that may serve as valuable archives for reconstructing past environmental changes in response to shifts in climate. This study presents a multidisciplinary analysis of two sediment cores from the overdeepened Wehntal Valley at ...

Terrain Synthesis and Authoring based on Iso‐Contours

open access: yesComputer Graphics Forum, EarlyView.
Abstract Digital terrains are central to realistic landscape depiction, yet authoring tools must balance perceptual realism with intuitive artistic control. We propose a compact vector‐based representation that models terrain as nested iso‐contours, inspired by geomorphology and cartography.

Biogeography of Atlantic Salmon in the Cape Breton Highlands, Canada

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT Atlantic Salmon (Salmo salar) populations have experienced significant declines in recent decades. In Canada, conservation efforts are divided into 16 designatable units (DUs) to address unique regional challenges among genetically distinct populations.

Chromosome fusions shaped karyotype evolution and evolutionary relationships in the model family Brassicaceae

open access: yesNature Communications
The ancestral crucifer karyotype and 22 conserved genomic blocks (CGBs) facilitate phylogenomic analyses in the Brassicaceae. Chromosomal rearrangements reshuffled CGBs of ancestral chromosomes during karyotype evolution.

Spatial–Temporal Heterogeneity of Wetlands in the Alpine Mountains of the Shule River Basin on the Northeastern Edge of the Qinghai–Tibet Plateau

open access: yesRemote Sensing
Alpine wetland ecosystems, as important carbon sinks and water conservation areas, possess unique ecological functions. Driven by climate change and human activities, the spatial distribution changes in alpine wetlands directly affect the ecosystems and ...
