Tracking individual seed fate confirms mainly antagonistic interactions between rodents and European beech

Food-hoarding granivores act as both predators and dispersers of plant seeds, resulting in facultative species interactions along a mutualism–antagonism continuum. The position this continuum is determined by the positive negative that vary with ratio between seed availability animal abundance, particularly for mast-seeding interannual variation spatial synchrony production. Empirical data on entire fate seeds up to germination influence rodents survival rare, lack consensus their Here, we quantified annual rain rodent abundance an old-growth European beech forest tracked 639 beechnuts seedling stage 84% successfully located. Over 4 study years covered range seed-to-rodent ratios, not single germinated after dispersal, illustrating predominantly antagonistic interaction beech. Therefore, our findings do support predator dispersal hypothesis partially contradict satiation hypothesis, highest number germinants intact were found situ intermediate crop, bumper crop. Our results underline necessity track germination.

Hay transfer is a nature-based and sustainable solution for restoring grassland biodiversity

Journal of Environmental Management, Год журнала: 2022, Номер 311, С. 114816 - 114816

Опубликована: Март 3, 2022

As we enter the United Nations Decade on Ecosystem Restoration, there is an increasing need for finding nature-based solutions restoration of grasslands across globe. Besides seed sowing, alternative methods that build locally available propagule sources, such as hay transfer, should also be considered and given high priority. The transfer from a donor site to serves double aim by introducing target species suppressing weeds. We tested applicability in restoring species-rich grassland former cropland Hungary, over six years post-restoration monitoring 2015 2020. sampled plant composition three sites (target state restoration) area surrounding site. found year after restoration, developed with 42 successfully established specialist had cover 45%. Most became second sixth year, but areas provided additional sources. Among eight analysed functional traits, mass transferred was best predictor establishment specialists, small-seeded advantage first restoration. Our results suggest can suitable solution local projects its potential utilized especially regions where are present sufficient quantity quality.

Anchoring grassland sustainability with a nature‐based small burrowing mammal control strategy

Journal of Animal Ecology, Год журнала: 2023, Номер 92(7), С. 1345 - 1356

Abstract Over the last 40 years, a burrowing mammal eradication policy has been prevalent on Qinghai–Tibetan Plateau (QTP). This is based similar programs in other areas and justified assumptions that mammals compete with livestock for forage contribute to grassland degradation. However, there no clear theoretical or experimental evidence supporting these assumptions. paper synthesizes ecological functioning of small natural grasslands discusses irrationality consequences sustainable grazing Past efforts have failed because increased food availability remaining rodents reduced predator populations led rapid population rebounds. Herbivores differ diet, mammals, especially plateau zokors Myospalax baileyi , different diet than livestock. In QTP meadows, induces shift towards plant communities fewer species preferred by more mammals. Thus, eradicating opposite effect, reduction vegetation. We suggest poisoning needs be reconsidered revoked as soon possible. argue incorporating density‐dependent factors such predation are essential maintaining low density. For degraded grasslands, we optimal approach decrease intensity grazing. Lower changes vegetation structure composition increases decreases abundance plants Such nature‐based management system maintains density at stable while minimizing human interventions.

Impacts of climate change and human activities on three Glires pests of the Qinghai–Tibet Plateau

Pest Management Science, Год журнала: 2024, Номер 80(10), С. 5233 - 5243

The range of Glires is influenced by human activities and climate change. However, the extent to which environmental changes have contributed this relationship remains unclear. We examined alterations in distribution driving factors Himalayan marmot, plateau pika, zokor on Qinghai-Tibet Plateau (QTP) using maximum entropy (MaxEnt) model a geographical detector (Geodetector).

Forest composition shapes seed‐rodent interactions in a gradient of broadleaves and conifers

Journal of Applied Ecology, Год журнала: 2024, Номер 61(8), С. 1944 - 1954

Abstract Non‐native tree species and mixed forests have been increasingly employed in forestry practice as a safeguard against climate change tool to foster biodiversity while providing economic benefits. Though these changes forest composition may affect animal communities ecosystem processes, they are seldom studied through plant–animal interaction perspective. Here we investigated how with varying proportions of native broadleaf ( Fagus sylvatica ) two conifers (introduced Pseudotsuga menziesii Picea abies rodents their interactions seeds. We surveyed terrestrial small mammal communities, estimated species' densities, assessed seed preference by rodents, collected data on environmental variables (understory density basal area), measured production tracked 1200 seeds 20 different plots northern Germany mast non‐mast year for . Forest influenced the between In lower proportion broadleaves, beech were harvested faster greater quantities, had diminished survival less often cached. These results agreement three other findings: (a) fate responded broadleaves irrespective conifer identity, (b) preferred nutritious over seeds, (c) higher during period when scarce (non‐mast year). Synthesis applications : This work provides evidence can without necessarily altering or population densities. Specifically, found no differences non‐native trees regarding community, seed‐rodent fate. Furthermore, provide service primarily preying upon , superior‐competitive species, thus mitigate dominance species.

Ecosystem services delivered by Brazilian mammals: spatial and taxonomic patterns and comprehensive list of species

For the 701 mammals that occur in Brazil (ca. 13% of extant worldwide), we attributed ES to each deliverer one based on their functional traits, known trophic interactions, expert knowledge, and by overlaying IUCN's distribution maps species. The term encompasses both ecosystem processes services, offering a broader perspective enables us investigate potential benefits people. We assumed species are currently listed as threatened IUCN most likely lost role. found 82% Brazilian (575 spp.) deliver at least 11 identified. Cultural services were associated with greatest number species, while carrion control, engineering, rodent control delivered fewer Although only 24% analyzed here endemic Brazil, 75% them ES. they also disproportionately risk, 57% considered have role endemic. Ecosystem service provision does not merely mirror spatial patterns mammal richness general, identified hotspots for across including its seascapes. Our comprehensive assessment provides clear overview myriad mammals, taxonomic explicit information service. Identifying mapping can contribute more effective management conservation programs focused optimizing supply conserving biodiversity.
