Anthropogenic pressures such as hunting are increasingly driving the localized functional extinctions of all or most large and medium-sized wildlife species in tropical forests, a phenomenon broadly termed defaunation. Concurrently these areas, smaller-bodied benefit from factors competitive release experience population increases. This transformation community can impact interactions ecosystem services seed dispersal seed-mediated geneflow with far reaching consequences. Evidence for negative genetic effects following defaunation is well-documented large-seeded plants that require frugivores long distance dispersal. However, how affects small-seeded (< 1.5cm diameter) plants, which dispersed by wide range body-sizes responses to anthropogenic threats, not well understood. To better understand reach defaunation’s impacts on plant communities, we investigated spatial patterns hyperabundant palm, Euterpe precatoria three sites representing distinct levels. We found significantly higher fine-scale structure among nearest-neighbor seedlings defaunated site recovering, partially relative faunally-intact site. Defaunation was associated shorter distances between adults lower adult seedling cohorts. No were detected inbreeding diversity; however, caution trends indicate influences distribution variation even inherently have broad suite agents, this could lead downstream diversity.

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%.

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 .

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.

Societal Impact Statement The conservation of pollinators is essential for sustaining the ecosystem services pollen transfer, which support crop production, biodiversity and health. While primary have been focus most efforts, subordinate or incidental largely overlooked. Animals that pass through vegetation may compensate pollination deficits in context ongoing pollinator declines. Such could potentially enhance gene flow among plants over greater distances more varied directions compared to alone. To fully benefit from these supplementary services, it preserve diverse habitats across broader landscapes spatial scales. Summary Terrestrial angiosperms primarily employ two strategies: anemophily zoophily. Anemophilous flowers produce large quantities small grains wind‐mediated transport, often inefficient. In contrast, zoophilous attract flower‐visiting insects, other invertebrates vertebrate using visual, olfactory cues, exchange rewards. However, non‐target animals, including mammals, birds arthropods, frequently visit flowering without consuming floral These visitors inadvertently transfer between plants, contributing fruit set. This phenomenon, termed “background pollination”, be particularly relevant mass‐flowering species, generalist flowers, riverine zoochorous where passage combined with static electricity, facilitates deposition. Detecting such mechanisms poses challenges traditional methods, as situ observation bagging experiments field. Emerging approaches, camera trapping examination wild‐caught animals' body surfaces, offer useful insights into interactions. Background likely complements anemophilous strategies, introducing additional complexity dynamics within plant populations.
