Highways associated with expansion of boreal scavengers into the alpine tundra of Fennoscandia
<p>1) Habitat fragmentation may affect species distributions through, for example, altered resource availability and shifts in species interactions. Fragmentation by roads has had negative impacts on Fennoscandian alpine ecosystems, with reduction of habitats and connectivity for alpine species. Concurrently, infrastructure development cause influx of subsidies through roadkills and litter, which may facilitate expansion of boreal scavenging species, such as the red fox (Vulpes vulpes), which may intensify negative interactions with alpine species. Hence, understanding the impact of subsidies within marginal alpine areas is imperative for successful conservation and management of particularly vulnerable alpine species.</p> <p>2) We used snow tracking and camera traps in three alpine tundra areas in Norway to investigate whether the presence of boreal scavengers were positively associated with highways during winter, and if this contrasted the pattern of a critically endangered alpine species, the Arctic fox (Vulpes lagopus). In summer, artificial nests were used to assess whether predation risk was related to proximity to highways.</p> <p>3) During winter, the occurrence of red foxes was higher close to highways and decreased with increasing distance to highways, while the arctic fox showed no discernible pattern. Red fox occurrence increased with the number of edible items of anthropogenic origin located along highways, whereas arctic fox occurrence decreased.</p> <p>4) The overall predation risk of artificial nests during summer was high (> 31.2%) and increased with proximity to the highway in the area with highest traffic volume. Synthesis and applications: Highways crossing alpine areas may attract boreal scavengers, possibly connected to increased access to subsidies of anthropogenic origin. Litter and food waste dominated available subsidies along highways in our study, and prevailing mitigating measures directed at reducing roadkill and movement restrictions may not be applicable to reduce negative effects of littering. We recommend actions focusing on informational campaigns, improved garbage disposal facilities and routines, and imposing fines for littering, to reduce negative impacts on vulnerable species. This is likely needed to achieve goals of "no impact" from the physical loss of habitats due to road development.</p>
Urban scavenging: Vertebrates display greater sensitivity to land-cover and garden vegetation cover than invertebrates
<p>1. Scavenging removes carrion or littered food waste from the environment, providing ecosystem services including nutrient cycling, reduced pathogen spread, and reduced waste management costs. These services are particularly important in urban environments, where high human population densities result in increased littered food waste. It is unclear how the magnitude of scavenging across urban-rural gradients is influenced by agent (vertebrates and invertebrates), land-cover type and patch size.</p> <p>2. We investigated scavenging provision by vertebrates and invertebrates across a gradient of urbanisation in 37 woodlands and 35 domestic gardens across Liverpool, UK. Sites were selected using random stratification across a gradient of urbanisation based on impervious surface cover. At each site, four different bait types were deployed either within vertebrate exclusion cages or exposed to vertebrates and invertebrates. The percentage dry weight loss of bait after 48 hours was used to quantify scavenging provision.</p> <p>3. Data were analysed using general linear mixed effects models (Gaussian error distribution) and a full model approach to assess 1) the relative contributions of vertebrates and invertebrates across an urban-rural gradient; 2) variation in scavenging between woodlands and gardens; 3) the effects of semi-natural vegetation cover on scavenging provision. We also consider patch size as a preliminary assessment of how fragmentation influences scavenging.</p> <p>4. Vertebrates contributed substantially more to scavenging provision than invertebrates across the urbanisation gradient. Vertebrate scavenging was substantially greater in woodlands than gardens, invertebrate scavenging was similar in both land-cover types. Scavenging increased with patch size in gardens, but not woodlands. Vertebrate scavenging increased with patch size, while invertebrate scavenging decreased. Within gardens, vertebrate scavenging increased with semi-natural vegetation cover.</p> <p>5. Scavenging-mediated ecosystem services are important in urban areas where food littering is frequent, and efforts should be made to facilitate these services. Urban woodlands and gardens both make important contributions to scavenging-mediated ecosystem services in urban areas, but woodlands' contributions are much greater. There is a need to increase the cover of semi-natural vegetation in gardens to increase their contributions, and protect and expand woodlands, especially in areas with a high demand for ecosystem services reliant on scavenging.</p>
Data - Scavenging in two mountain ecosystems: distinctive contribution of ants in grassland and non-ant invertebrates in forest
<p>Data set and analyse used in the manuscript title "Scavenging in two mountain ecosystems: distinctive contribution of ants in grassland and non-ant invertebrates in forest". In this study we <span>quantify the relative contribution of ants, non-ant invertebrates and vertebrates in scavenging nitrogen-rich (insect carcasses) and carbon-rich (seeds) baits in two contrasting mountainous habitats in Brazil (grasslands and forests). Testing the folowing predictions </span><span> (1) baits are more likely to be removed from the forest floor than grassland due to higher plant biomass in forest than in savannas <span>(Miranda et al. 2014)</span>, which could indicate a higher animal biomass in the forest. However, (2) ants would have higher relative importance in scavenging in open habitats (grasslands) than in closed (forests) because in open habitats, ants have higher activity <span>(Bucy and Breed 2006)</span>, richness <span>(Castro et al. 2020)</span>, and there are more dominant species <span>(Andersen 2019)</span>. (3) The role of ants in scavenging is not compensated for by other taxa when ants are absent. Finally, (4) the removal rates of animal-based baits on the ground are higher than seed baits in both environments, since animal resources are more limiting than plant resource in most habitats<span> (Kaspari and Yanoviak 2001, Bar-On et al. 2018)</span>.</span></p>

Directed endozoochorous dispersal by scavengers facilitate sexual reproduction in otherwise clonal plants at cadaver sites
<ol> <li>The regeneration niche of many plant species involves spatially and temporally unpredictable disturbances, called recruitment windows of opportunity. However, even species with clear dispersal adaptations such as fleshy berries may not successfully reach such elusive regeneration microsites. Ericaceous, berry-producing species in the northern hemisphere demonstrate this dispersal limitation. They are said to display a reproductive paradox owing to their lack of regeneration in apparently suitable microsites despite considerable investment in producing large quantities of berries.</li> <li>Cadavers generate vegetation-denuded and nutrient-rich disturbances termed cadaver decomposition islands. Cadavers attract facultative scavengers with considerable capacity for endozoochorous seed dispersal. We hypothesize that cadaver decomposition islands facilitate recruitment in berry-producing ericaceous species due to endozoochorous dispersal directed towards favorable microsites with low competition.</li> <li>We examined seedling establishment within a permanent, semi-regular 10 × 10 m grid across an ungulate mass die-off on the Hardangervidda plateau in southeastern Norway. Competing models regarding the relative importance of factors governing recruitment were evaluated, specifically cadaver location (elevated seed rain) and microsite conditions (competition).</li> <li>We found that cadaver decomposition islands did facilitate seedling establishment, as cadaver density was the best predictor of seedling distribution. Other important factors governing seedling establishment such as percentage cover of soil and vascular plants alone were inadequate to explain seedling establishment.</li> <li> <i>Synthesis:</i> This study provides a novel understanding of sexual reproduction in species with cryptic generative reproduction. The directed nature of endozoochorous dispersal combined with long-distance dispersal abilities of medium to large vertebrate scavengers towards cadavers allows plants to exploit the advantageous but ephemeral resource provided by cadaver decomposition islands.</li> </ol>
