Contrasting Patterns of Raccoon (Procyon lotor) Spatial Population Genomics Throughout a Rabies Management Area in Eastern North America

Evolutionary Applications, Journal Year: 2025, Volume and Issue: 18(5)

Published: May 1, 2025

ABSTRACT Wide‐ranging, generalist species provide both interesting and challenging opportunities for research questions focused on population structure. Their continuous distributions ability to occupy diverse habitat types can obscure genetic signals of ancestry geographic clustering. However, spatially informed approaches are notable high‐resolution identification clusters that often elude more classical clustering models. The northern raccoon ( Procyon lotor ) is a broadly distributed in North America, with populations habitats ranging from dense urban rural landscapes. Wildlife management agencies have an interest understanding ecology, given their propensity human‐wildlife conflicts zoonotic diseases.

Information regarding species' status at a regional scale is instrumental for effective conservation planning. Some regions of southwestern Europe, such as Portugal, albeit included in the Mediterranean biodiversity hotspot, lack detailed assessment distribution patterns several taxonomic groups, carnivores. Moreover, information scattered, often unreliable and biased towards some species or regions. This study aimed reviewing existing knowledge on mammalian terrestrial carnivores to analyse research trends, update checklist assess their historical current patterns.

Do alien predators pose a particular risk to duck nests in Northern Europe? Results from an artificial nest experiment

Biological Invasions, Journal Year: 2021, Volume and Issue: 23(12), P. 3795 - 3807

Abstract Several alien predator species have spread widely in Europe during the last five decades and pose a potential enhanced risk to native nesting ducks their eggs. Because predation is an important factor limiting Northern Hemisphere duck nest survival, we ask question, do increase loss ground ducks? We created 418 artificial nests low densities around inland waters Finland Denmark 2017–2019 monitored them for seven days after construction using wildlife cameras record whether visit prey on more often than species. sampled various breeding habitats from eutrophic agricultural lakes wetlands oligotrophic urban environments. The results differed between two countries, which likely reflect local population of raccoon dog ( Nyctereutes procyonoides ), species, was most common mammalian visitor all its occurrence reduced survival.

Although cautious about concluding too much visitations nests, these imply that already support abundant effective predators, whose relative frequency visitation suggest they potentially add over predators.

Abstract The raccoon is listed among the invasive alien species of EU concern requiring management actions. Projections its global distribution have been mainly based on climatic variables so far. In this study, we aim to address impact land cover (LC) in North America and Europe. First, identified LC types which observation sites are predominantly located derive preferred types. Second, used an ecological niche modelling (ENM) approach evaluate predictive power information current patterns raccoons both ranges. Raccoons seem be more often associated forested areas mixed landscapes, including cropland urban areas, but underrepresented vegetation-poor with largely coinciding order compare climate variables, conducted principal component analyses all respective variable sets (climate variables) PC that together explain 90% total variance set as predictors. Land only models resulted patchy projected habitat suitabilities showed a higher performance compared Europe, suitability seems exceed observed occurrences, could indicate further spread potential We conclude important drivers, well spatial raccoon.
