The primacy of endozoochory for the maintenance and expansion many woody plant populations is well known, but seed dispersal not understood most species. This especially true rare species, where small population size low fruit production can limit field- or observation-based experiments. Additionally, effect environmental heterogeneity on disperser movement rarely investigated has been shown to improve estimates spatial patterns dynamics. We used simulation experiments explore effects Lindera subcoriacea dispersal, a shrub from southeastern United States with avian-dispersed seeds. Our incorporated simulated five bird based either landscape permeability straight path rules. anticipated that permeability-based would result in greater distances effectiveness, which characterizes both quantity quality. Generally, we did find differences between However, had deposition into suitable habitat during flight (23 vs. 1%).

Abstract Forest restoration is fundamental to overcoming biodiversity crises and climate change. In tropical forests, animals can improve forest recovery as they disperse >70% of tree species. However, representing in change policies remains challenging because a quantitative assessment their contribution carbon lacking. Here we used individual-based models assess frugivore-mediated seed rain open areas along fragmentation gradient. Movements large birds were limited landscapes with <40% cover, although small continued seeds. Large seeds late-successional species higher storage potential. Their restricted movement therefore reduced potential biomass future forests by 38%. Maintaining cover >40% essential optimizing animals’ success. Active (for example, planting trees) required more fragmented achieve targets.

Natural regeneration in forest management, which relies on artificial planting, is considered a desirable alternative to reforestation. However, there are large uncertainties regarding the natural processes, such as seed production, dispersal, and seedling establishment. Among these dispersal by wind must be modeled accurately minimize risks of regeneration. This study aimed (1) review main mechanisms models, their characteristics, applications (2) suggest prospects for models increase predictability With improving computing observation systems, modeling technique has continued progress steadily from simple empirical model Eulerian-Lagrangian model. Mechanistic approaches with kernel have been widely used attempted directly incorporated into spatial models. Despite rapid development various wind-dispersal only few studies application We identified potential attributes that cause high poor simulation results scenarios: topography, pre-processing data, inherent complexities processes. can further improved incorporating abscission wind, spatiotemporally complex environments, (3) collisions canopy or ground during flight, (4) secondary long-distance predation.

Plants produce nutritious, fleshy fruits that attract various animals to facilitate seed dispersal and recruitment dynamic. Species-specific differential selection of size by multiple frugivorous disperser assemblages may affect the subsequent germination ingested seeds. However, there is little empirical evidence supporting this association. In present study, we documented conflicting pressures exerted on five carnivores a mammal-dispersed pioneer tree, date-plum persimmon (Diospyros lotus), in subtropical forest. Fecal analyses revealed these acted as primary dispersers D. lotus. We also observed sizes were selected based body mass species-specific, confirming "gape limitation" hypothesis; three small (the masked palm civet Paguma larvata, yellow-throated marten Martes flavigula, Chinese ferret-badger Melogale moschata) significantly preferred disperse smaller seeds comparison with control obtained directly from wild plants whereas largest Asiatic black bears (Ursus thibetanus) larger Seeds dispersed medium-sized hog badgers (Arctonyx albogularis) not different regarding influence gut passage germination, arboreal agents (martens, civets, bears) enhanced success terrestrial species (ferret-badgers badgers) inhibited process compared undigested These enhance heterogeneity dynamics thus increase fitness through diversification regeneration niche. Our results advance our understanding mechanisms have important implications for forest ecosystem dynamics.

Abstract Seed dispersal by frugivorous animals is a key process for plant populations and communities. When frugivores consume fruits, seeds are temporarily retained inside their guts until seed deposition. Hence, information on retention times essential to estimate seed‐dispersal distances. Although it well known that affected the body size of frugivores, there an important knowledge gap effects species traits, such as pulp content. Here, we comprehensively address whether which traits affect in birds. On one hand, conducted first set experiments assess variation among 31 dispersed single bird species, second five guild passerines. other literature review retrieving 231 interactions involving 155 55 from nine different avian orders. had negative at three levels addressed this study: larger seeds, shorter times.

ABSTRACT Individual‐based simulation has become an increasingly crucial tool for many fields of population biology. However, continuous geography is important to applications, and implementing realistic stable simulations in space presents a variety difficulties, from modeling choices computational efficiency. This paper aims be practical guide spatial simulation, helping researchers implement individual‐based avoid common pitfalls. To do this, we delve into mechanisms mating, reproduction, density‐dependent feedback, dispersal, all which may vary across the landscape, discuss how these affect dynamics, describe parameterize convenient ways (for instance, achieve desired density). We also demonstrate models using current version simulator, SLiM. additionally natural selection—in particular, genetic variation can demographic processes. Finally, provide four short vignettes: pikas that shift their range up mountain as temperatures rise; mosquitoes live rivers juveniles experience seasonally changing habitat; cane toads expand Australia, reaching 120 million individuals; monarch butterflies whose populations are regulated by explicitly modeled resource (milkweed).

Information about seed dispersal effectiveness (SDE) for plant species of conservation concern is rarely available to inform management strategies and actions. For Lindera subcoriacea (bog spicebush, Lauraceae), a rare endemic dioecious shrub the southeastern United States, we examined influence two intrinsic five extrinsic drivers on number proportion seeds either dispersed, or predated pre- post-dispersal. The dispersed characterizes quantitative component SDE, while post-dispersal predation can affect qualitative SDE. Using fruit counts, traps, removal depots over multiple years, estimated that approximately 28% L . are lost pre-dispersal predation, 69% 3% fail disperse, 65% We observed substantial variation in these three processes among individuals. also found both (plant height, crop size) (understory cover, time since last fire, conspecific fruiting neighborhood, substrate) differentially influenced processes. identified four generalist, seasonally frugivorous, avian visitors at individuals likely act as variably effective dispersers, Northern Cardinal ( Cardinalis cardinalis L.) predator. Rodent granivores were important predators. magnitude our estimates suggest that, given low fecundity , should emphasize facilitating reducing effects predation.
